A mobile phone that is getting slower and slower.
The problem of mobile phone slowing down is bound to be encountered as long as the phone is used for a long time. However, today's processors are obviously not a matter of arithmetic, so where is the core of slowing down? As far as the author's experience is concerned, there are too many broken files, which are mainly the cache of picture files in various groups, video caching, thumbnails, various emojis and so on.
NAND for mobile phones is now generally UFS protocol, and eMMC has been basically eliminated.
The ROM of the mobile phone is NAND flash memory, and the protocol used is generally UFS. But in fact, you see all the press conferences PPT, there will be special publicity, high-speed your phone's UFS3.1 how fast, but this data is generally aimed at large files, continuous transmission of 1700MB/s, random read and write about 200-3000MB/s. But what about the fragmented files? No one will tell you.
Semiconductor storage depends on 4K random read and write ability.
We can see it in the same SSD. People who understand SSD will not look at the peak reading and writing speed, but will only see the reading and writing ability of 4K, but the 4K ability of UFS3.1 is not tested. When your phone's various WeChat groups are bombarded with emojis and pictures, that's when your phone slows down.
Wechat 8.0.22 special clean-up
If you look at the introduction of Wechat's upgraded features, it's almost always the same "fixed some known problems." If you use your mobile phone for the first half of a year, in the general storage space statistics, you will find that the previous Wechat version, statistics are very slow, often take a few hours, my Wechat has more than 100 GB, statistics do not work overnight.
But 8.0.22 has improved this ability, and the statistical speed has become much faster. In the past N hours, it only takes a few minutes to count it out. And the file space will be divided into three types: cache, chat history, and other data.
After cleaning up, there is only "only" more than 60 GB of Wechat.
In this, the cache can be cleaned, chat records can be cleaned according to groups or individuals, and other data can not be cleaned. The author cleaned up the chat data around 70GB this time, and many of the chat records were backed up continuously, even dating back to seven or eight years ago, an active group of more than ten GB is very normal.
These data are actually dead data. A large number of cached facial expressions, image thumbnails, video thumbnails, a variety of video files ranging from a few seconds to a minute or two. They are all dragging down the speed of mobile phones. The remaining free space on my own mobile phone has suddenly increased from a few hundred MB to 66.5GB! More space is not an intuitive feeling, intuitive feeling is that with the progress of cleaning, the speed will be significantly improved. I personally, except for the key work-related groups, after all the information of other groups has been cleaned up, the response speed of the mobile phone has become very fast!
Why use Wechat to bring it?
There is no software to clean up your phone, but why use Wechat's own software? The reason is simple, because Wechat comes with can be specifically cleaned up to each group or individual conversation. But third-party software generally belongs to "six relatives do not recognize", can only tell you how many pictures, videos account for how much, you want to delete all, this kind of rough treatment is obviously not good.
Wechat comes with tools that can clean up each chat.
Wechat upgraded to improve the statistical speed and cleaning speed, it should be that the Wechat team is also aware of this problem is a pain point troubling users, can be specially cleaned up, no longer become a drag on the entire system, even if your phone configuration is not high, as long as timely clean up the files in the chat history, it can still be often used.
