In 2022, in addition to the fermenting of the metaverse, NFT and virtual currency issues, the specifications of smartphones are more mature than ten years ago, and some functions that were originally only available on high-end mobile phones are now distributed to mid-range and even entry-level mobile phones. can have. “Freedom Times” takes stock of 4 key points of mobile phone selection in 2022, so that readers can avoid outdated specifications when buying a phone this year, and buy a new phone that can really last a long time!

➤How to choose a processor: Qualcomm 6 series, 7 series, 8 series look at it this way
The Snapdragon series launched by the US mobile phone chip maker Qualcomm is the processor chosen by many Android mobile phone brands. For example, Samsung’s Galaxy S22 series launched in February this year uses Qualcomm’s top-level processor Snapdragon 8 Gen 1.

However, just like the variety of Intel processors, there are also many models of the Snapdragon series, but generally, the 6 series processors named “Snapdragon 6XX”, such as Snapdragon 695, 690, etc., are mid-level positioning chips, and The “Snapdragon 7XX” series is mid-to-high-end; “Snapdragon 8XX”, such as the Snapdragon 865, 888, and the chips whose naming convention was fine-tuned at the end of last year and changed to 8 Gen 1 are top-grade chips. Mobile phones using this type of chip are originally The factory price is mostly above NT$20,000, which is also a high-end flagship.

Generally speaking, there are generally two basic indicators of current mobile phone processors, including CPU processing performance and GPU graphics performance. The former is closely related to the performance in general daily operations, while the latter is extremely important for image processing such as mobile games. In terms of the three series of Snapdragon, the 8 series still has an absolute advantage in both. Compared with the 7 series and 6 series, it has a clear lead, and the GPU gap is the largest; and if the 7 series chooses the top version, such as Snapdragon 780G, the total performance is about the same as that of the 8 series three years ago, and the chip of the 6 series is about the level of the 8 series six years ago.

It should be noted that since there are no revolutionary new applications in mobile phones recently, the performance of mobile phones has been improved year by year. In recent years, there has been a phenomenon of excessive CPU performance. If you only have daily Internet access needs, most Qualcomm chips should be able to meet the requirements, but if you have plans to play games or simply edit pictures or cut small videos, it is best to give priority to buying mobile phones equipped with 8 series Qualcomm chips. For the money, you can also consider last year’s 8-series chips, such as the Snapdragon 888, which are still a bit more efficient than the current 7-series and 6-series.

➤How to buy memory? 2022 must buy at least 6GB + 128GB
In addition to the processor, memory size and storage space are also very important, which directly determine the rate at which new apps and new web pages are opened. A large enough memory can also execute multiple applications at the same time, avoiding frequent “killing the background” by the system. , it is particularly critical for Android phones with larger memory access; with larger capacity, users can also store more photos, or temporary archives of important apps such as LINE.

At present, although many mid-level or entry-level models still use 4GB memory and 64GB storage space, as 6GB memory and 128GB models have been distributed to some Android models that cost 7,000 yuan, users are also Time to steer clear of the 4GB RAM or 64GB storage models. Many tests also show that in 2022, if you want to use a mobile phone stably, you must have at least 6GB of memory, and if you want to use it smoothly, 8GB is the basic threshold.
Apple, which is relatively conservative in terms of storage space, will also increase the base capacity of the new iPhone 13 from 64GB to 128GB in 2021. Although the new devices, the ninth-generation iPad, iPad mini and iPad Air still start from 64GB, but Apple also reminded users to consider a larger 256GB space on the official website purchase page, which shows that 64GB will consume more system performance in 2022. In recent years, it is only at the level of “good enough”. For users who want to use their mobile phones for a longer time, it is best to choose a model with a larger capacity.

➤Does the screen frame rate matter? 90 / 120Hz will become mainstream
Although high frame rate is still a relatively exclusive feature of mid-to-high-end mobile phones before 2021, many mid-range and even basic mobile phones from many brands have begun to adopt this specification, such as Samsung’s entry-level phones Galaxy M32, A22, showing high frame rate It is a relatively mature specification. It is recommended that users should try to choose a model with a mechanism above 90Hz when purchasing a machine.
Through the higher, rather than traditional 60Hz frame rate, users will have a better sense of smoothness when viewing mobile apps and swiping. The difference can reach the level of “can’t go back”, but at the same time, it may also make the mobile phone more power-hungry . Some manufacturers, such as Samsung and Apple, use the form of “adaptive” to reduce power consumption. For example, 120Hz is only turned on when the user swipes, and only 10hHz is used for static images. However, this function is still exclusive to flagship mobile phones. Said that if you are concerned about power consumption, the system will also provide options for users to set, only using the traditional 60Hz.

However, compared to the Apple products that the Android camp is keen to adopt and sell well in Taiwan, 120Hz high frame rate is currently only available on the iPhone 13 Pro series and iPad Pro series, and has not been delegated to the basic iPhone 13. Become one of the very few high-end phones without 120Hz. This also implies that Apple is very likely to make the new iPhone fully have a high frame rate in 2022.

➤The adoption of intermediate machines is also expanding! IP67 / 68 waterproof and dustproof can not be missed
“Waterproof and dustproof” has been exclusive to flagship mobile phones in most stages of the development history of smartphones. In the early days, it was even the main feature of high-end mobile phones of certain brands such as Sony. There are mid-range phones like Samsung’s Galaxy A52, or Sony’s Xperia 10 III. According to the international protection level specification, IP67 means that it is completely dustproof and can be immersed in static water at a depth of 1 meter, while IP68 can be placed deeper (according to the manufacturer’s specification). In principle, it can cope with most small accidents in life, such as overturning Water glasses, but not recommended for water activities.

The Korean media “The Elec” also predicts that in 2022, Samsung will start to more generally use IP67 / 68 waterproof and dustproof design in mid-range models, so as to improve the competitiveness of its mid-range models against Chinese manufacturers, even low-end models. Models are also expected to be adopted. Although the current IP67 / 68 models are not yet popular with 90 / 120Hz high frame rate, but with the expansion of the smartphone leading Samsung, it is expected to become a more popular specification in 2022. It is recommended that users should not miss it when they start. .
