Apple regains the top of global mobile phone sales, iPhone 13 sell good in China

After a lapse of one year, Apple once again returned to the top of the global mobile phone sales, and Xiaomi ranked third.


According to data from Canalys, Apple accounted for 22% of global smartphone shipments in the fourth quarter of 2021, a slight increase of 1% year-on-year, due to supply chain and epidemic factors. On average, for every five mobile phones shipped, one is an iPhone. Samsung ranked second with a market share of 20%, a year-on-year increase of 3%; Xiaomi maintained its third position with a 12% share, and OPPO and vivo ranked among the top five with 9% and 8% shares respectively.

Some analysts attributed Apple’s return to the top 1 global mobile phone market share after three quarters to the excellent sales performance of the iPhone 13, especially in Greater China. “The iPhone’s popularity in the Chinese market has surprised many, and the aggressive pricing of its flagship device maintains a strong value proposition,” said Canalys analyst Sanyam Chaurasia.


Nanfang + reporter was informed that before this, Apple has been ranked as the top 1 smartphone shipment in China for 6 consecutive weeks, and the strong performance of the Chinese market has also helped Apple become the smartphone manufacturer with the most shipments in the world in Q4 2021. Xiaomi Group executives also stated on the conference call in the third quarter of 2021 that Xiaomi’s domestic market share declined in the third quarter, which was directly related to the “strong performance of the iPhone 13.”

In addition to the mobile phone business, Apple is also the fastest-growing computer brand in 2021. According to statistics, in 2021, the global PC shipments will exceed 341 million units, of which Apple computer shipments will rank fourth, Lenovo first, HP second, and Dell third.

Samsung’s 4nm process is said to be inferior

It is said that Samsung Electronics’ wafer foundry process technology is not as good as others, and the problem of overheating of the processor cannot be solved for a long time. “All have the problem of high temperature and high energy consumption.

Qualcomm to stay with Samsung for Snapdragon 895, may switch to TSMC's 4nm  tech for 895+ : rumor - PhoneArena

BusinessKorea and The Korea Times reported that the 3D mark test conducted by Phoenix New Media showed that the Motorola Edge X30 smartphone equipped with Qualcomm Snapdragon 8 Gen 1 had a serious heat problem, up to 58 degrees Celsius. The processor overheats, causing the smartphone to drain power rapidly.

Not only the Snapdragon 8, but also Samsung’s self-produced Exynos 2200 processor, has also experienced performance and yield disputes. Samsung originally planned to hold the Exynos 2200 conference on January 11, but it was postponed temporarily. The outside world suspected that the yield rate was too low and the chip quality could not meet the standard, forcing Samsung to change its schedule. Samsung moved to reveal the Exynos 2200 on January 18, but did not announce the performance improvement of the CPU and GPU compared to the previous generation, nor the number of clocks per core.

Industry insiders said there was a problem with Samsung’s 4nm process that allowed the Exynos 2200 to overheat. Well-known whistleblower Ice Universe revealed that Samsung originally expected the Exynos 2200 clock to reach 1.9 GHz, but the overheating caused the clock to drop to 1.29 GHz.

Some analysts say Samsung’s process is to blame for the underperformance of Qualcomm and Samsung’s processors; the iPhone’s A-series processors are manufactured by TSMC.

However, some people defend Samsung, claiming that the processor’s overheating and poor performance are not only affected by the process, but also need to consider issues such as IC design, components, and smartphone performance.

Last year, Samsung invested 40 trillion won (about 33.55 billion U.S. dollars) in semiconductor fields such as memory, foundry and equipment, said Lee Seung-woo, an analyst at Eugene Investment and Securities. But this year, TSMC is preparing to drop 50 trillion won in wafer foundry. In view of the huge investment required for foundry, from the current business structure, it seems that Samsung is difficult to catch up with TSMC in the field of foundry.

Samsung Galaxy S22 series model exposed

As time goes on, the exact release date of the Samsung Galaxy S22 series of smartphones has been subject to several rounds of speculation. The latest news points to this point in time on February 9. However, some overseas bloggers recently released the hands-on video of the three models of the Galaxy S22 series, which is the first to let netizens know about the rear lens module, screen design details and color matching.

Overseas video bloggers are the first to get started with the Galaxy S22 Ultra model. It can be seen that the number and arrangement of the rear lens modules are almost similar to the previous generation S21 Ultra, but this time, the metal frame like the S21 Ultra has been cancelled to make the visual The feeling (especially the black shell version) is more harmonious and unobtrusive.

Although it is the S22 Ultra model, it can be seen that the stylus position is suspected to be designed at the bottom right corner of the fuselage. In this way, the “essence” of the Samsung Note series will be “inherited” by the S series, which may further prove that Samsung will From 2022, the dual flagship (Note/S) product layout will be integrated into one flagship product series.

From the details of the fuselage screen, it can be seen that this time the S22 Ultra will use a micro-curved screen design, which is believed to bring a better screen experience.

The relevant hardware parameters of the S22 Ultra are almost the same as the previously exposed information, except that the 1TB storage version and the model using the Exynos 2200 version will be postponed after the S22 series is launched.

The parameters of the S22 Ultra rear lens module are also similar to the previous speculation.

Finally, the video blogger also briefly explained the three models of the Samsung S22 series. From the above comparison chart, we can see that the appearance of the S22 Ultra is more angular, and with the addition of a stylus, it is indeed almost the same as its own Note 20 Ultra.

It has to be mentioned that according to the forecast of research institutions in the ranking of global smartphone shipments in Q4 in 2021, Apple has surpassed Samsung to become the champion with a market share of 23.2% due to the excellent record of the iPhone 13 series, while OPPO and Xiaomi are ranked after Samsung. The market share is more than 10%. Therefore, if Samsung does not win more attention through the upcoming flagship S series, then perhaps in 2022 Samsung can continue to rely on its own cost-effective A series to win a certain market, but whether it can keep the second world ranking in the future is also very important. Hard to predict.

Some news of Huawei Mate50 leaks out, all 4G and 5G versions are available

It is now 2022, and it has been more than a year since the Huawei Mate 40 series was released on October 22, 2020. Due to well-known reasons, the 5G version of the Huawei Mate 40 series is hard to find. Currently, on the official website of Huawei Mall, the Huawei Mate 40 series machines are all in the state of “not for sale.” Will this continue? The answer is no, because the successor to the Huawei Mate 40 series, the Huawei Mate 50 series, is coming.

There are more and more news about the Huawei Mate 50 series. According to the analysis of Zhang Guobin, CEO of Electronic Innovation Network, the Huawei Mate 50 series will support 5G and use the 14nm production line of domestic RF chips to completely get rid of the blockade restrictions; the Kirin 9000 chip is still used, but it is The last generation, and continues the Kirin + Qualcomm dual version; if the domestic self-developed 5G RF chip triggers the force majeure factor again, the Qualcomm version of the Huawei Mate 50 series will not support 5G.

Three recent blog posts by digital bloggers respectively revealed the release time, some image information and chip information of Huawei Mate 50 series.

The blogger also released a picture of the back of the small-screen version of the Huawei Mate 50 series. The back is still similar to the design of the Huawei Mate 40 series. According to the blogger, the engineering machine has Kirin 9000 chip and Snapdragon 8 Gen1, which further confirms the speculation of Kirin/Qualcomm dual version. Judging from the rear image module of the exposure map, the camera in the middle is most likely a black and white camera used to enhance the image quality, but the position of the flash has not been found.

The Huawei Mate 50 series is also expected to be equipped with HarmonyOS 3.0. In the dynamic responses of social network users, the current developer preview version of HarmonyOS 3.0Beta1 only provides demonstration and pre-adaptation functions, and will not be open to developers for update use. The developer version of Beta2 will open developer updates to improve system capabilities and software and hardware adaptation, and it is expected to start user internal testing in April.

Apple iPhone 14 has a total of 4 models, the price was leaked in advance

The iPhone 13 series released by Apple in 2021 will truly make consumers feel the beauty of 13.

It is precisely based on the “high cost performance” of the iPhone 13 series that has promoted the surge in sales of the iPhone 13 series. And Apple also took advantage of the high sales of the iPhone 13 series to win a number of sales champions in one fell swoop.

For many consumers, although the price of the iPhone 13 series is very good, they are still very interested in Apple’s new flagship iPhone 14 in the fall of 2022. There are even many people in the industry who advocate: don’t rush to get the iPhone 13 series, because the upcoming iPhone 14 series is better.

However, judging from the recent exposure of related digital bloggers and technology media for the iPhone 14 series, in addition to the fact that the iPhone 14 series is about to cancel the design of bangs and use a pill punch screen, which has attracted the attention of consumers, The price of the leaked iPhone 14 series was also heavily discussed.

It is reported that Apple’s upcoming fall new iPhone 14 series in 2022 will be divided into 4 models. As far as the price is concerned, the iPhone 14 series will increase the price of the whole series. Among them, the price of the highest version of the emperor will exceed one hundred and one hundred US dollars.

There is no doubt that this price of the iPhone 14 series is quite unfriendly to a group of “waiting parties”.

On January 12, the media reported that the price of the iPhone 14 series will be increased by around $100. Among them, the base iPhone 14 is priced at $799, and the high-end iPhone 14 Pro Max starts at $1,199.

From this point of view, the price of the top version of the iPhone 14 Pro Max exceeds $1100, which is completely reasonable.

In fact, looking at various exposures about the iPhone 14 series on the Internet, Apple chose to increase the price of the entire iPhone 14 series, which is also expected by consumers.

In terms of appearance design, the iPhone 14 series will cancel the bangs design that has remained unchanged for Apple’s iPhone for thousands of years, and instead use pills to hollow out the screen. Display industry analyst Ross Young revealed that the iPhone 14 Pro uses a centered double hollow screen design, in which the Face ID lattice module is placed in the round hole, and the front camera and the Face ID infrared lens are placed in the pill opening.

Although from the perspective of visual effects, the dual-hole design of the iPhone 14 Pro is not aesthetically pleasing, but it improves the screen-to-body ratio of the phone to a certain extent and is more practical.

It is worth mentioning that in addition to the upgrade of the appearance design, the imaging system of the iPhone 14 series will also achieve certain breakthroughs. Trend Force, a research institute, revealed that the iPhone 14 Pro will replace the previous 12-megapixel wide-angle lens with a 48-megapixel lens, while supporting 8K video recording. In addition, the author learned that in order to further improve the user experience of consumers, Apple will also solve the problem of less light entering through “pixel binning”.

In terms of performance configuration, in order to further widen the gap between different products, the upcoming Phone 14 series will also be different in terms of processors. As far as I know, the basic iPhone 14 and iPhone 14 Max may continue to use the A15 processor; while the high-end versions of the iPhone 14 Pro Max and iPhone 14 Pro Max use the A16 processor, Apple’s strongest chip.

For the upcoming iPhone 14 series, which upgrade are you looking forward to more?

Should Android 12, iOS 15 be updated? 3 major points of mobile phone system update, the key is in hand

We know that mobile phones are composed of two parts: hardware and software. With the continuous advancement of technology, while the hardware specifications are constantly improving, the software has also ushered in a major upgrade. Among them, the one that attracts the most attention is the system part. Whether it is iOS or android, the system is constantly “evolving”, so the system push update notification is actually a normal thing.

However, although it is not difficult to upgrade the mobile phone system, the system itself is very complicated. Many times, a little uncertainty can lead to big usage problems. This also makes many users worried. So if you want to update the system of the mobile phone, let’s take a look and you will know.

  1. Problems that may occur after the mobile phone system is updated
    Today, with the increasing number of system functions, the system is also becoming larger and larger. The most direct impact of continuous system updates is that it will take up more storage space.

In fact, the system update of the mobile phone is no different from the installation of the APP. Both need to download the installation package to the local, and then restart the installation. The system firmware itself is a very large file, which will only be larger after decompression, and will occupy a large part of the ROM space.

This is not the end, the mobile phone system is a program that is always running. This means that it will also take up part of the memory space. Therefore, when the mobile phone memory and flash memory are fixed, the system will become larger and larger, which will squeeze more mobile phone space. Coupled with the running of other programs, it is not surprising that the phone freezes.

In addition, the increasing system functions will bring some other problems, such as fast power consumption, software incompatibility and so on. The former is mostly related to system optimization. After the new system is installed, the CPU and system algorithms will be continuously optimized in the background. As a result, the mobile phone will naturally have the problem of increased power consumption. Therefore, many times we will find that the power failure of the mobile phone after the major version update is the most serious, and it usually takes a period of use to stabilize.

As for software incompatibility, it is actually rare, but it does exist. It also often occurs after a major version of the system is updated, and some APPs may have problems such as being unusable and crashing. They are basically related to the software development side. They have not kept up with the development rhythm of new systems, resulting in incompatibility between software systems. You can first confirm whether the APP itself needs to be updated to match the new system.

Of course, the occurrence of these risks is always linked to “probability”. All we can do is to minimize these risks. Therefore, whether to update the mobile phone system frequently depends on the specific situation!

  1. It is not recommended to update frequently if the performance is too low or old mobile phones
    Generally speaking, mobile phone manufacturers update the system, in addition to fixing security loopholes and some bugs, the main job is to add new functions to the mobile phone. The “price” is that the demand for hardware performance will also increase, which is naturally nothing for flagships with “excessive performance”, but it is different for old mobile phones.
12 Fresh Ideas to Repurpose Your Old Android Devices

Thinking about our own purchase experience, the new mobile phone just bought, even if it is a thousand yuan cheap phone, is often very smooth. However, with the continuous update of the system version and the loss of hardware, the old models will become more and more stuck due to insufficient hardware performance. This is especially true for mid-to-low-end mobile phones that have been used for 2-3 years.

Undoubtedly, with the continuous updating of the system, the emerging new functions are gradually increasing the load on the hardware. For friends who use old mobile phones, if there is no urgent need for upgrades, such as patching security holes and patching bugs, Or maybe there are new features that really appeal to you, and it’s better not to update.

Correspondingly, if your mobile phone has strong performance, or is a new mobile phone, there is nothing to worry about. It is generally recommended to update. It is easy to adapt to the new mobile phone, it is unlikely to have serious bugs, and the experience will be improved.

  1. The large version should be updated as “prudently” as possible, and the small version can be updated “frequently”
    Of course, in addition to depending on the situation of the mobile phone, we can also start with the large version and the small version for the system itself. Generally speaking, for some older mobile phones, when updating the system, try to update the large version of the system with caution, and the small version can be updated relatively “diligently”.
A History Of Android Versions: Since Initial Release To Till Date

The so-called major version means that there will be a qualitative change in the system update, including functional improvement, which may involve all aspects of experience. Such as daily interaction, animation, function expansion, etc. These updates are generally not just small changes, but changes to the bottom layer of the system. And most of them are adapted and upgraded for some new models. Even if the old models support the new system, the user experience must be incomparable with the new mobile phones.

Therefore, for such a large version of the update, it is recommended that you be cautious. Don’t update right away. You can wait and see and pay attention to other users’ feedback on this. After waiting for a while to make sure there are no problems with this major version update, update the phone again.

iPhone battery | 4 tips to extend life and battery life

The market share of the iPhone has been quite impressive. Anyone who is using an iPhone must also know that the “battery health” can be seen on the phone. If the battery is too worn out, replace the battery. Otherwise, there will be a dilemma of insufficient battery life and shutting down at once. Recently, some netizens asked in the Facebook community, how much does the battery wear out before it needs to be replaced?

iPhone 7电池更换- iFixit Repair Guide

How often should the iPhone battery be replaced? Experts revealed that the “health level” is less than the battery and the battery will die quickly. A netizen posted on the Facebook community that his iPhone 11 has been used for one year and eight months, and the battery health remains at 80%.

As soon as the post came out, netizens left messages to share the usage status “I have 75% left on 11 in two years…”, “7+ has used 4 years of health remaining 78%, and it is obvious that it is easy to burn the machine after running to replace the battery in the auxiliary factory. The power consumption also feels a bit fast, and I regret the whole thing”, “The i8 is currently 85%, and it can last for a while.”

Judging from the comments of netizens, most of the people have used it for a year before the battery health began to decline significantly. Apple’s official website battery health replacement guide also points out that after an iPhone battery is charged 500 to 800 times, the battery life may drop to 80%. As long as it is close to or below 80%, you will find that the iPhone has abnormal power consumption, and the battery should be replaced at this time.

In addition, Apple’s official website also detailed that there are 4 tips to “maximize” battery life and life:

  1. Update the software to the latest version: Software updates also improve energy-saving technologies.
  2. Avoid extreme ambient temperature: 16°C ~ 22°C is the ideal temperature range, avoid exposing the device to an environment above 35°C, otherwise it may cause permanent damage to the battery.
  3. Remove some sheaths before charging: charging in the protective sheath may cause the device to overheat and affect the battery’s capacity.
  4. When storing for a long time, the battery should have half the charge. If you plan to store the unit for more than six months, it is best to keep it at 50% charge. A full charge may shorten battery life, and a full discharge may render it impossible to recharge later.
