TWS headset new “war”, OPPO true wireless headset and AirPods, how strong?

I don’t know how long it has been since the first generation of AirPods was released? The correct answer is more than three years, and it is precisely the emergence of it, which makes true wireless headphones usher in a rapid leap. Nowadays, people have also begun to adapt to the habit of carrying wireless headphones when going out.
In 2019, Apple has launched the 2nd generation AirPods and the noise-reduction version of AirPods Pro in succession, letting people see its technology leadership in wireless headphones. However, for Android users like me, although I admire the strength of AirPods, I am still afraid that the system will be a bit unsuitable, so I finally decided to buy a wireless headset suitable for Android phones.
Coincidentally, at the end of 2019, OPPO also launched its own true wireless headset Enco Free. You know, OPPO used to be a giant in the MP3 and MP4 industries. After so many years, this product must have its uniqueness. I would say nothing and immediately placed an order after it was released.
I have to say that this headset is really good-looking, the box is very small and very suitable for carrying around. Of course, the focus is on the headset. Its overall shape is very smooth, and it will not look awkward when worn on the ear. Coupled with the clever arc transition at the bottom of the headset, it doesn’t look like a wired headset has its wires cut.
Of course, the biggest difference between OPPO Enco Free and semi-in-ear headphones like AirPods is that it has two wearing methods, divided into semi-in-ear and shallow-in-ear, and provides three sizes of ear caps. And because of the protection of soft liquid silicone, this is also a good choice for users who like in-ear headphones.
So, how is this headset different from AirPods in use? The first thing to say is the delay that I can barely feel after wearing it. With Reno 3 Pro, OPPO true wireless headphones achieve 120ms low latency, which undoubtedly surprised me.
Because AirPods can only achieve a delay of 140ms. Although it usually has little effect on listening to songs, in a game such as “Peace Elite” that requires high accuracy, this slight gap may be the enemy going up and down the stairs. Time, so obviously the delay needs to be as low as possible.
For many AirPods users, another upgrade of OPPO Enco Free is to make Apple “heart-struck”, that is, gesture interaction is more versatile, in addition to the basic tap on the headset to answer and hang up the phone, or to play music, OPPO true wireless headphones can also slide to adjust the volume, which is more convenient.
It is worth mentioning that AirPods currently only supports the wake-up of Siri, but OPPO Enco Free is compatible with other Android brand voice assistants except for Brepo’s smart assistant Breeno, so it will not have much impact on most mobile phones…
As for sound quality and endurance, OPPO Enco Free also performs quite well. Because it uses the current industry-leading ultra-dynamic speakers, it can fully restore the details and dynamic range of multiple components, which is enough to bring users professional sound performance. In terms of battery life, it can also listen to music for 5 hours from a full blood state. If you add a charging case, it can reach 25 hours, which is full of strength.
From this point of view, the strength of OPPO Enco Free can really be described as “born for smartphones”, coupled with its support for Android system, it is a pretty good choice for non-Apple users. What’s more, such a wireless headset can be bought for the price of 699 yuan. Compared to AirPods, which costs as high as 1,246 yuan, Apple users are inevitably also excited. At present, they can enjoy a discount of 30 yuan. Don’t miss it.

Global true wireless headset sound quality ranking

In the past two years, the biggest trend of Bluetooth headsets is the popularity of “truly wireless” headsets. Whether it is the popularity of Apple AirPods or major audio manufacturers, they have launched their new true wireless Bluetooth headsets. Compared with traditional Bluetooth headsets, That said, the true wireless headset removes the wire around the neck, and the two earbuds truly achieve wireless connection, providing more compact portability and lighter wearing comfort, without being tied by wires.


Under normal circumstances, call clarity, sound quality, endurance, and Bluetooth stability are the four core indicators of true wireless Bluetooth headsets. The author has also successively started several real wireless headsets in succession. The prices vary widely, and the actual experience It ’s also quite different, here is an inventory of the three best-selling Bluetooth headsets today.

First, NANK N2 true wireless Bluetooth headset

South Carolina Bluetooth headset is the latest super-hot Bluetooth sports headset, which costs about 300 yuan, but has powerful explosive power and heavy bass, equipped with a Bluetooth 5.0 chip, and innovative polymer composite diaphragm, with the Toronto Music Master million adjustments, To make the sound performance richer and more delicate, to hear the ears, and to be immersive, you won’t lose thousands of dollars in sound quality. Because of its superior cost performance, it is praised by major technology media websites as “ the best choice for cost-effective Bluetooth headphones 2019 “.

South Carolina Bluetooth headsets have spent a lot of thoughts on comfort, sound quality and endurance. In addition to first-class hardware configuration, they even established a human ear database and developed a ring-shaped fit design that conforms to Asian ear types. 25 ° flexibility Ear caps, with a very light body of the only 4g, can be worn for a long time without pain. In terms of sound quality, we invited the Canadian musician William Arnaldo to work with 20 European and American tuners for two years. For different music styles, millions of adjustments were made to create a more excellent and pure sound. This headset has super long battery life, has a 3,000 mAh charging compartment, can provide 120 hours of battery life for the headset, and the charging compartment can charge the mobile phone in reverse, you don’t have to worry about the mobile phone and Bluetooth headset running out of power!

Second, the iron triangle

If you love noise reduction! If you are voice-controlled! If you are Yan Kong! Then you must not miss it.
Advantages: 11mm moving coil. At present, there is no one in the major brands of true wireless headphones. The sound quality is very strong, the bass is good, the mid and high frequencies are excellent, the frequencies are good, and the drums are clear. Listen carefully and you can find some ordinary music. The background sound indicates that the analysis is still good, the comfort is very high after listening for a long time, and the power is 6 + 9 for a total of 15 hours of durability! The price is nearly two thousand, it is recommended that everyone can buy the iron triangle directly at an affordable price, and whoever knows the sound quality.
Third, smartisan true wireless Bluetooth headset
The true wireless Bluetooth headset uses a dual technology combination of a Bluetooth 5.0 chip and a loop ceramic antenna. In conjunction with IBRT’s ear-to-ear transmission technology, the delay and synchronization problems of the left and right ears are greatly reduced. At the same time, the left and right ears are used alternately to avoid long-term wear on one side. Discomfort.

Smart watch comes out to make Apple Watch smarter

The Apple Watch is already one of the most powerful smartwatches on the market, but a smart strap released at CES this week will go far beyond what Apple has developed. This AURA strap is a strap with its own intelligent function, which can do things like track moisture and body composition, and then wirelessly send results and statistics to the iPhone.
By using bio-impedance, the strap can perform rapid body composition analysis, which means it can measure body fat and muscle mass. It can then determine the level of hydration and calculate the risk of heart failure, a feature that the Apple Watch can provide, but with additional data, the AURA strap can provide a more accurate judgement. The AURA strap design is different from other Apple Watch straps because it uses sensors placed inside to collect information. It also uses standard Apple Watch lugs, so users can easily connect it to the watch.
According to official estimates, the AURA strap can be replaced with a battery and can last for six months. It obviously supports Apple’s HealthKit and is completely waterproof, just like the Apple Watch, so it can be worn at any time even while taking a bath. It is available in two sizes to fit different Apple Watch versions. The AURA strap takes about 20 seconds to obtain human data, and these statistics are automatically transferred to the iPhone and Apple Watch.
The strap comes in four colors, black, green, red, and gray, and is already available for pre-order for $ 99. The first batch of products is limited and delivery will begin in early April. used iPhone 6s plus

The current Apple AirPods Pro version is priced at $ 249 in the United States, for reference only. used iPhones

Answer from Intel: The computer has expanded the memory, but it still keeps saying that there is not enough memory?

News on December 30 Today Intel China answered a computer memory problem that everyone may encounter. The computer expands the memory but always prompts that the memory is insufficient? What is going on?
According to Intel, this is most likely a code error in a program that caused the computer’s memory to overflow, and previously occupied memory could not be released. Users can enter the Windows Task Manager to see which program is taking up too much memory. Uninstall or update this program to a stable version.
If you are only using one program, the system prompts that the memory is insufficient, and other programs can run normally, then the possible reason is that the program file is damaged, which causes memory problems. However, Windows does not indicate exactly that the program is damaged, so please try to remove and reinstall the program, and then run the program again. If the system no longer prompts for insufficient memory, then the original program file is indeed damaged.
In addition to the above, it may be solved in the following scenarios:
Restart the computer
If you exit the program without restarting the computer, the program may not be able to return memory resources to the system. Restart your computer to free up system resources, then run the program again or perform an interrupted task.
Too many programs open
If there are too many programs running at the same time, there is not enough memory to run other programs. At this time, for multi-document interface (MD1) programs, such as Word, Excel, etc., please close all documents except the current document and exit the currently unused program, and then you may be able to continue to be interrupted due to “out of memory” Task.
Kill virus
System infection with computer viruses is also the culprit of insufficient memory. When the system encounters an “out of memory” error, please use the latest antivirus software to kill the virus, or after removing the computer virus, the “out of memory” problem is resolved. used iPhones

Sony WI-1000XM2 experience is still the strongest neck-mounted noise reduction headset

Neck-mounted wireless noise-canceling headphones now seem to be a marginalized product.
Extremely different from head-mounted and true wireless, neck-mounted wireless noise-canceling headphones are now more placed in the entry market and become a common low-budget entry option.
However, there are still labels that insist on updating the flagship neck-mounted noise-canceling headphones.
Then, it’s still Sony.
As early as December 10th, Sony officially launched a new generation of wireless earphones WI-1000XM2. Regardless of function, specification support or configuration, the WI-1000XM2 has reached the standards of the Sony 1000X series family 3 generations. Compared with the previous generation, WI-1000XM2 also has many design optimizations. Just looking at the book performance, it is indeed the strongest neck-mounted wireless noise reduction currently configured.
In this experience, we not only have to see what kind of user experience the WI-1000XM2 can achieve in this configuration but also take the Sony 1000X family as an example to discuss but do also we need a flagship neckband? Wireless noise-canceling headphones.
Soft structure, lightweight
Regardless of the packaging or the main body of the headset, the first impression that WI-1000XM2 gives me after getting started is-small and light.
Compared with WI-1000X’s old-fashioned packaging, the WI-1000XM2’s box is really much less. In addition to a small storage box of the same color, there are only six sets of replacement earplugs and different rubber plugs for the memory foam box Three groups. The charging cable for the headset, the dual 3.5mm aircraft adapter, and the 3.5mm audio cable are all stored in the carton under the rubber plug.
As mentioned in the previous release report, the WI-1000XM2 switched to a soft collar similar to the WI-C600N, which can be folded and put into this small storage box when the user stores it. There is also a piece of cardboard with instructions in the box. Users can put other accessories according to the instructions so that they are not afraid of being lost or forgotten when they are used.
▲ Inside WI-1000XM2, outside WI-1000X
Compared with the original WI-1000X, the soft structure WI-1000XM2 can be deformed when pressed by external forces, reducing the chance of damage to the fuselage. In addition, the soft structure can also fit the neck and clothes through deformation when worn, reducing the foreign body sensation when worn.
▲ Inside WI-1000XM2, outside WI-1000X
With the weight reduced from 71g to 58g, the comfort of the WI-1000XM2 has also been significantly improved.
Although the soft collar can improve the wearing, there is still a lot of room for improvement in the overall experience.
First of all, the WI-1000XM2 headphone cable is still relatively short, just enough to maintain normal wearing. However, because the wire is maintained in a state that is just long enough, the wire has no extra length to be fixed around the ear, and the excessive shaking of the wire will cause a more obvious stethoscope effect during use.
▲ Actually, it ’s okay to go back forcibly and bring stability, but it ’s just weird.
In addition, this time Sony moved the buttons for collar playback and noise reduction control to the headset line.
With the addition of the ‘by-wire’ structure, the effect of the stethoscope effect caused by the wire shake will be even greater. Especially in the pure noise-reduction state without music, the effect will be more obvious. If you are used to the experience of wearing true wireless noise-canceling headphones, this ‘disadvantage’ of WI-1000XM2 may make you crazy.
Compared with the collar, the shape design of the headset has not changed much, mainly the details.
Although the new headphones use Sony ’s dual-microphone noise reduction design commonly used in third-generation products, the size of the headphones has not changed much but is more compact than the old ones. Thanks to the changes in materials, the WI-1000XM2 headphones are also a lot lighter. With the newly added inclined earphone design, the wearing stability of the WI-1000XM2 headphones has also been improved.
But many times because of the length of the wire, the advantages of the slanted design and lightweight headset body have been offset. If Sony can lengthen the cable, or go crazy, an MMCX wireless module can create an ear-hook structure, which can reduce the impact of the stethoscope effect and improve stability. It is also a very convenient solution.
Except for the name, the rest are all three-generation configurations
Ai Farner has emphasized in previous reports that the WI-1000XM2 is equipped with the third generation configuration of the 1000X family. The core of the family’s third-generation configuration change is from this QN1.
When the WH-1000XM3 was released, Sony introduced the HD noise reduction processor QN1. QN1 replaces the ‘S-MASTER HX + Noise Reduction Control Chip’ solution used on WH-1000XM2 and WI-1000X. One chip is directly responsible for the two tasks of noise reduction and audio processing. When the chip was released, Sony also said:
With the WH-1000XM3 after QN1, the noise reduction effect is increased by 4 times. In addition, the audio processing capability has also been improved. Now it can handle 32-bit lossless audio, whether it is sound or noise reduction, it has made greater progress than the original.
Later, Sony also introduced QN1e on the true wireless noise-canceling headphones WF-1000XM3. QN1e can be understood as a QN1 specially developed for low power consumption requirements, with the same noise reduction and improvement effect, but the upper limit of audio processing will be reduced from 32bit lossless to 24bit lossless. But this effect is not large, and it is actually enough for WF-1000XM3 that does not need LDAC.
Originally, we thought QN1e would be launched on WI-1000XM2. However, Sony this time frantically plugged the QN1 directly onto the WI-1000XM2, giving it the same flagship configuration as the WH-1000XM3.
Thanks to the investment of QN1 and LDAC encoding support, WI-1000XM2 can also support Hi-Res Audio playback in wireless mode. Sony also changed the WI-1000XM2 wired audio output port to a 3.5mm interface this time. When the headset is restored to the wired mode, the sound does not need to be processed by the headset, and the AUX cable of the 3.5mm interface also has a lot of options, even if the cable is lost, it is easy to make up.
In addition to the core QN1, the WI-1000XM2 is also equipped with SENSE ENGINE technology and air pressure adjustment function, which can adjust the noise reduction effect by detecting changes in the current environment through a mobile phone. With Sony ’s Headphones Connect app, 20 levels of noise reduction can be adjusted. With the support of air pressure adjustment, users can reduce the effect of air pressure by using noise-canceling headphones on the aircraft.
In terms of audio technology, WI-1000XM2 also uses DSEE HX digital audio. Even in the case of smart devices that do not support high-specification codings such as LDAC or aptX HD, users can open DSEE HX in Headphone Connect to compensate for the sound. Although it doesn’t work for everyone and every song, sometimes the compensation is good.
In terms of battery life, the WI-1000XM2, like the WI-1000X, supports 10 hours of battery life. This time, the WI-1000XM2 also supports the fast charge mode of ‘charging for 10 minutes and playing for 80 minutes’. This performance result is also enough for daily use, but if you encounter long-distance flights, the pressure is still a bit high. If QN1e is replaced in the WI-1000XM2 and LDAC is also supported, you can also eat Hi-Res Audio in wireless mode, which can also reduce power consumption and improve battery life.
Now, it’s more like Sony made a trade-off for performance and specifications.
But anyway, WI-1000XM2 is now the most powerful Sony neck-mounted headset available. Whether it is noise reduction or audio processing, it is also on top of Sony’s own. If you are particularly sensitive to the specifications and configuration of the cable, then WI-1000XM2 will still make you feel value for money.
If the name can keep up, that’s even better.
Noise reduction is more natural
After the configuration is improved, the WI-1000XM2 has also improved in terms of noise reduction and hearing.
In addition to the technical blessing of QN1, this time Sony also added a dual feedback microphone structure similar to WF-1000XM3 to the WI-1000XM2. In addition to receiving external noise information, it can also receive feedback sounds in the ear, which can improve noise reduction. The amount of information received by the chip, thereby improving the noise reduction effect.
In fact, the noise reduction of the WI-1000XM2 is stronger than that of the WI-1000X. The presence of noise reduction effect is stronger, and the noise floor control will be better than WI-1000X. These are perceptual improvements.
In addition, the output of the ‘Ambient Sound’ mode of the WI-1000XM2 will be more natural than that of the WI-1000X. The ‘digital taste’ brought by the expansion of the human voice is reduced. While amplifying the surrounding environment, the microphone’s radio reception The effect is less obvious. Here, you can feel the efforts of Sony in processing algorithms.
In addition, I also briefly compared AirPods Pro in the experience. When both are fully worn, the presence of the WI-1000XM2 noise reduction mode will also be slightly stronger than that of the AirPods Pro. However, it is still a bit of a hassle to make the WI-1000XM2 completely suitable for wearing, and many adjustments need to be made when wearing it.
If possible, I still hope it can use the same length of wire as the first generation, and then pull the buttons back into the collar, so that it will be more stable when worn.
WI-1000XM2’s noise reduction has indeed improved, you can feel these improvements. But compared with the difference between WH-1000XM2 to WH-1000XM3, the evolution of WI-1000XM2 is actually not so obvious.
However, some users who have already experienced WI-1000XM2 said that the noise reduction effect of WI-1000XM2 is actually close to WH-1000XM3, but from our experience, WI-1000XM2 does not seem to have such an effect.
This may also be related to the earliest ‘Engineering Edition’ we got. Earlier versions did not make adjustments to the software, the performance may not be at its original level, and the experience may be different. Or Sony will also improve the noise reduction performance at this stage through firmware updates.
Sound quality is more prominent?
In terms of headset configuration, the WI-1000XM2 uses a combination of one circle and one iron, and the parameter specifications are the same as the WI-1000X.
But unlike the WI-1000X, the WI-1000XM2 places the WI-1000X on the moving iron unit below the moving coil and moves it to the front of the moving coil. Sony has such a treatment, it is estimated that it is also related to the design of the headset. The volume of the WI-1000XM2 is smaller than that of the WI-1000X. It is also normal to adjust the internal structure of the headset.
However, the sound performance of the WI-1000XM2 has also changed a lot after the sound guiding structure of the headphones has changed. Coupled with the changes in the sound processing capabilities of QN1, the sound of WI-1000XM2 is indeed more prominent than that of WI-1000X:
▲ (Artist: Ayasa | Album: “ANISONG COVER NIGHT Vol.2” | Connection and equipment: NW-ZX300A (LDAC) | Specifications: 24bit 96kHz Hi-Res | Noise reduction mode: Noise reduction on)
▲ (Singer: Chen Jian’an | Album: “Original” | Connection and Equipment: NW-ZX300A (LDAC) | Specifications: 24bit 96kHz Hi-Res | Noise Reduction Mode: Noise Reduction On)
The first feeling of WI-1000XM2 just getting started is that the low frequency is much more prominent than before. The drumbeat has improved a lot, and the fullness of the sound has also increased. The overall vocal feel will be thicker than the WI-1000X, and the adaptability to pop music will be stronger than the WI-1000X.
The performance of the vocals is also good. Although there is a little bit forward, the overall sound does not matter. The stability of the human voice is also good, and users can still clearly sing in a fixed position, and there will be no obvious looseness. These are actually Sony’s advantages, and the WI-1000XM2 can also inherit this advantage.
The processing of the details is actually good, and some parts of the restoration will be better than the WI-1000X. However, the overall sound of this WI-1000XM2 in our hands will still be a bit rough, and the resolution will not be brought out, and the sound will still sound a little muddy.
This is believed to be an individual problem. The previous WI-1000X will not have this problem after long-term use. It is estimated that the engineering version of the firmware has not been adjusted.
Still the strongest, but do we really need it?
Overall, the WI-1000XM2 is also a neck-mounted wireless noise-canceling headset with very good configuration and experience.
After using the same configuration as the WH-1000XM3, the WI-1000XM2 has achieved a comprehensive improvement in noise reduction and audio performance. The body is also lighter than before and storage is simpler. For:
I don’t want to hang my headphones often
Afraid that true wireless is easy to lose
I want better connectivity, sound quality, and configuration standards, but I do n’t want to wear a headset

For users with these needs, WI-1000XM2 is an option worth considering.
In addition, Sony will adjust the price after the distribution of goods and sales are stable. The price of 2499 yuan is the same as the previous generation. If you encounter the price reductions of various shopping festivals in 2020, there is still a possibility that you can shout out the real fragrance.
Yes, the WI-1000XM2 is really strong, but do we really need it?
Those who pursue specifications and the ultimate noise reduction effect may more often choose a wireless noise reduction headset. The head-mounted type has more space and can accommodate larger size units and batteries. There are fewer trade-offs and restrictions on power consumption and performance than the neck-mounted type, and the endurance performance can be better than the thin-necked body.
If the pursuit of convenience, the advantages of true wireless will be more obvious than the neck-hanging type. Without the restrictions of wires and collars, there will be fewer restrictions on the wearing of truly wireless earphones, and the wearing experience will be better than the neck-hanging type that may have a “stethoscope effect”.
Although there is still some instability in transmission, as the chip manufacturers continue to optimize their solutions, the stability of true wireless headphones is stable. If you want to buy used iPhones, there are used iPhone 6s plus, used iPhone 7, used iPhone 8 plus on sale in Energyitshop!

5G mobile chip “war” starts MediaTek Teana 800 layout mid-to-high-end

On the eve of the release of OPPO Reno3, MediaTek held a communication meeting to share with guests the current situation of 5G chips and the plan and layout of MediaTek in the 5G era.
At the event, MediaTek announced that in addition to the previously released Teana 1000 flagship 5G SoC, a new 5G chip, Teana 800, will be announced early next year to jointly form the Teana product line.
The Teana 800 series is mainly aimed at mid-to-high-end smartphones and directly targets the Qualcomm Snapdragon 765 SoC. According to the plan, this chip will be released in the first quarter of 2020, and the second quarter of next year will see the launch of terminal phones equipped with Teana 800.
MediaTek announces Teana 800 series chip
Teana 800 layout mid-to-high-end
For details of this chip, MediaTek did not disclose too much. If it follows the previous routine, Teana 800 will be exposed, warmed up next year, and then released. Now MediaTek has given it a preview in advance.
The fierce competition for mobile chips in the 5G era is evident.
Earlier, Huawei launched the first integrated 5G SoC, the Kirin 990 5G, and it will soon be commercially available to mobile phone terminals; Qualcomm launched the two mobile platforms Snapdragon 865 and Snapdragon 765 at the Snapdragon Technology Summit at a stretch, with flagship and mid-to-high-end 5G mobile platform; Samsung has also come up with its own 5G SoC, and reached a cooperation with Vivo to export. This series of actions made MediaTek have to be more active on the 5G battlefield.
In fact, the Teana 800 has long been included in MediaTek’s plan, but this time it was just an appearance. Before the Teana 800, we also saw another Teana product, namely the Teana 1000L on the OPPO Reno3. From the information exposed earlier, the Teana 1000L has been adjusted on the basis of the previously released Teana 1000, more in line with the positioning of Reno3 mid-to-high-end mobile phones.
Dr. Li Yanji, Assistant Associate, MediaTek Wireless Communications Division
Regarding this Teana 1000L, Dr. Li Yanji, associate director of MediaTek Wireless Communications Division, said that it is not a custom product of MediaTek and OPPO, but just adjusted according to user needs to make it more consistent with the product positioning of terminal manufacturers. From this point of view, the Teana 1000L is more like the current MediaTek to complement mid-to-high-end mobile phones. In the future, the Teana 800 will continue to assume the task of downward expansion.
Positioning flagship Teana 1000
Speaking of the Teana 1000 SoC, MediaTek positioned it as the flagship 5G chip, which not only integrates the 5G baseband but also supports WiFi 6 and 5G dual-card dual standby. According to the official announcement of 510,000 AnTuTu running points stable 5G Flagship chip echelon. MediaTek has always emphasized the advantages of 5G integration solutions-better power consumption experience and saving mobile phone design space.
MediaTek believes that integrated 5G chips are an inevitable trend in the future, and Qualcomm may have their own considerations for not doing so. However, Dr. Li Yanji made an interesting point: can a chip without 5G baseband be considered a 5G SoC? He believes that the Snapdragon 865 chip with the Snapdragon X55 baseband can be called a 5G mobile platform, but as far as the Snapdragon 865 is called a 5G chip, it will feel uncomfortable. Because there is no 5G in the Snapdragon 865.
Regarding Apple’s lack of integrated chips in the 4G era, Dr. Li Yanji gave his personal opinion. As we all know, Apple does not have its own baseband chip. In the past, it has cooperated with Intel and Qualcomm. If it wants to do integrated SoC, it needs two assistants. In the future, if Apple has its own baseband, the chances of moving towards integration will be great.
Teana 1000 is very competitive in parameter configuration
As a 5G SoC, the Teana 1000 only supports 5G networks in the Sub-6GHz band and does not support millimeter waves. MediaTek believes that at this point in time, Sub-6GHz is the absolute mainstream. According to the official data of MediaTek, there are currently 56 operators supporting 5G in the world, of which only three are using millimeter waves, and these three also support Sub-6GHz. The millimeter-wave technology MediaTek also has reserves. In the future, the use of millimeter waves will be determined according to the network of the operator.
As for the issue that the Teana 1000 ISP only supports 80 million pixels, MediaTek’s explanation is that the current camera experience is not necessarily proportional to the number of pixels. At least for now, the difference between 100 million pixels and 64 million pixels is not large, or even better. MediaTek believes that at this point in time 80 million pixels are sufficient, and it will definitely advance in this area in the future to support higher pixels.
The battle for 5G chips has just begun
In fact, from the perspective of various parameters, MediaTek Teana 1000 is a very competitive 5G SoC. Although AnTuTu runs 510,000 points less than 560,000 points of Snapdragon 865, MediaTek believes that Teana 1000 and Snapdragon 865 are the only chips in the market with more than 500,000 points. The performance is not much difference between the two It is more important to see if high performance can control the fever.
After the performance and configuration have reached a new level, MediaTek has finally come up with its “flagship core” in the 5G era. However, they also face a problem on how to get rid of the inherent impression in the past and accept a new MediaTek technology.
Although the Teana 1000 series chip is positioned as the flagship, it debuted on mid-to-high-end mobile phones. Although the performance has the opportunity to suppress the opponent’s mid-to-high-end products, in the end, he failed to prove his strength in the flagship field at a stretch. In this regard, Li Yanji believes that, of course, high-end can highlight the brand strength, but after all, flagship users are limited. From another perspective, more users will use it on mid-to-high-end products and experience its benefits.
For MediaTek, the “war” of 5G chips for smartphones has just begun. Whether 5G can be used to win market share and word of mouth depends on the final performance of Teana.

More than Snapdragon 865 Meizu 17 exposure: all support 5G

Meizu 17 will officially debut in Q1 next year.
On December 26, Meizu employee @ 石 见 -Zoro Weibo said that I suggest you wait for 5G mobile phones. Some netizens left a message, whether Meizu 17 still has a 4G version, and the answer is “I don’t know, but the previous interviews of the bosses were AII IN 5G”.
According to the official information, Meizu 17 will be equipped with the Qualcomm Snapdragon 865 flagship platform, which is the first batch of Snapdragon 865 models listed in the world, supporting SA and NSA dual-mode 5G, and is Meizu ’s first 5G mobile phone.
Except for the Snapdragon 865, details about Meizu 17 are temporarily unknown. The most concerned about the screen is part of Meizu. Since the 16th series released last year, Meizu has always adopted a full-screen design with symmetrical top and bottom, no bangs and no digging. It is unknown whether this design will continue to be used.
Of course, Meizu 17 may also consider using a digging screen solution. The current small-aperture digging screen technology has matured, and the front camera can be embedded in the status bar to achieve a perfect visual balance.
All in all, as another new work created by Meizu Technology founder Huang Zhang, Meizu 17 is worth looking forward to.  used iPhone 6s plus

iPhone to do a full screen, but know how difficult it is to have a full screen phone

Yesterday I was swiped by a message on Weibo. This news is not new, even something we will talk about almost every year-iPhone is going to use a full screen, and it is still ‘official real hammer’.
This can startle me. After all, the iPhone has removed the bangs, but everyone is looking forward to it. I quickly went to the cover page of the Apple Support Twitter homepage mentioned in the news to find the truth.
At first glance, the two women’s iPhones in the photos do seem to use a screen without bangs, which seems to be a full-screen iPhone.
But just when I thought the full-screen iPhone really was coming, I magnified the picture and took a look. In fact, both iPhones in the photo had bangs, but the reflections and black background put the bangs in hiding.
Enlarge the picture 100%, you can actually see that there are bangs.
The iPhone can achieve a truly comprehensive screen, which is a great thing from an aesthetic point of view. From the user’s point of view, a phone with a full front screen can bring us a visual impact. But from a technical point of view, building a true full-screen phone is not something that can be built.
Especially on devices that have a tight internal space like a cell phone.
▲ Samsung Galaxy Note Edge is the originator of curved screen phones Picture from AndroidPit
Mobile phone manufacturers can always capture the consumer’s mentality, so they are not trying to make a true full screen on the mobile phone. Looking back, the manufacturer even went crazy to cover the screen with the entire front of the phone.
If it weren’t for the drilling screen, the current mobile phone may have various forms such as a flip cover and a slide cover.
▲ Huawei Mate30 and Mate30 Pro
To say that the originator of full-screen mobile phones, I have to mention the “visual full-screen” mobile phones based on Samsung Galaxy Note Edge. This group of products will reduce the width of the two sides of the screen by bending the screen, and visually make the sides of the screen close to the design without BM black edges and borders.
This design can be seen on some flagship mobile phones so far, and it has also been upgraded to a waterfall screen with greater curvature, replacing physical interaction with screen interaction.
Last year, there was a wave of slider revival in the mobile phone circle. Xiaomi, Glory, and Lenovo each launched their own slider phones, placing the screen “simple and rude” on the upper layer, reaching a screen ratio of 93% (currently the limit of mainstream bar phones) Screen ratio is 91%).
In addition, there is a mechanical platform to separate the camera from the screen while maintaining the bar shape. Like the previous Vivo NEX and OPPO Find, they are all outstanding mechanical structures. Later dual-screen mobile phones brought the manufacturer’s pursuit of screen ratio to the extreme, and its purpose was to make more room for the front of the mobile phone.
▲ vivo NEX
From a morphological point of view, the manufacturer’s pursuit of a full-screen can be called crazy, but after an in-depth analysis, there is a technical compromise behind every design. Although manufacturers are moving towards the goal of true full-screen, they must not ignore the several openings near the screen-sensors.
In fact, while expanding the proportion of the screen, manufacturers have been trying to hide the sensors of the handset and light distance under the screen, trying to minimize the openings on the front of the phone, so the two tasks of expanding the screen and hiding the sensors are in sync. ongoing.
However, the addition of functions such as face recognition, gesture recognition, and so on, has led to more and more mobile phone sensors, which makes the screen-to-body ratio contrary to mobile phone functions.
When the Google Pixel 4 first came out, some people thought that this phone was a “big forehead”, but they ignored the 8 sensors on the top of the screen. In addition to the handset, camera, light distance and other parts, these 8 sensors are also used for motion detection The Soli radar and the recognition of the dot matrix projector, which makes the Pixel 4 has a sensitive motion recognition system.
Even if the radar and infrared sensors are removed, at least three openings for the handset, light distance sensor, and camera are needed above the screen.
Of course, mobile phone manufacturers have not moved the sensors to other places, so that at least three sides of the screen have a fringe design that does not affect the look and feel. Xiaomi MIX ’s sensors are a good example. However, this design that subverts the traditional use of logic was finally replaced by the slider of Xiaomi MIX 3. The reason may be that the slider is more in line with the design requirements of the full screen, but even so, the slider design was only scratched by several manufacturers in the end. A gust of wind.
In fact, whether it is a slider or a lift design, these are just temporary solutions introduced by the manufacturer to ‘reduce’ the sensor space. More complex body structures increase not only the manufacturing cost of the mobile phone, but also occupy a large amount of money. Interior space and tightness. Although manufacturers can give data of hundreds of thousands of openings and closings when advertising, in fact, everyone’s habits and scenarios are different, and the mechanical structure is naturally not as strong and durable as the traditional straight bar.
Would you give up the body because of the bigger screen?
▲ OPPO Find X specially designed electric lifting platform
Therefore, at present, the mainstream candy bar mobile phone to increase the proportion of the screen is mainly implemented in three ways: waterdrop screen, drilling screen, bangs screen. The first two are by leaving a space for the camera lens and hiding the sensor on the screen. The bottom or bezel realizes a full-screen design, even reducing the number of sensors; Liu Haiping is still the current method to take into account both functions and screen ratio. The only problem is that it needs to occupy a certain display space.
▲ Vivo NEX uses under-screen photosensitive + micro-slit infrared design
So in the final analysis, whether a mobile phone can achieve a true full-screen is actually not only a question of mobile phone manufacturers and screen suppliers but also whether sensor technology can achieve accurate under-screen sensing. From the current point of view, the OLED-based under-screen handset, light, and infrared sensors can already be hidden in the screen and side seams, but the under-screen camera is still a hurdle for manufacturers to go through.
At this month’s Future Technology Conference, OPPO exhibited the first prototype machine designed with an under-screen camera. With the help of the screen-dense pixel small hole perspective principle, the camera can shoot through an OLED screen.
▲ OPPO under-screen camera design patent
▲ Optimized before and after contrast shooting under the screen
However, ‘photographing under the screen’ is not solved by launching a set of patents. From the proofs released by OPPO, it can be seen that the original film of the under-screen camera performs generally in terms of color and sharpness compared with ordinary front shots, and requires post-optimization to To achieve the performance of the ordinary front camera.
In fact, it also invisibly tests the manufacturer’s ability to adjust the camera hardware and camera system. In addition, CMOS components specially designed for under-screen shooting may be needed.
Of course, in addition to the OPPO family, Xiaomi, Vivo, and Huawei also have patents for the under-screen camera, which are generally achieved by customizing the screen material and the characteristics of the material transmission. Therefore, we can see that the design of full screen and shooting under the screen will definitely be the future development direction of mobile phones, but under the current technical conditions, these concepts still have many technical problems that need to be overcome by mobile phone manufacturers in conjunction with screen and camera suppliers It takes at least 1-2 years from the research and development to the investment of ‘true full-screen’ mobile phones on the market.
So the “full-screen iPhone” at the moment is actually more of a self-heal, not to mention the official “real hammer”. If you want to buy used iPhones, there are used iPhone 6s plus, used iPhone 7, used iPhone 8 plus on sale in Energyitshop!
