Recently, XDA found that Google added a piece of code related to memory and multitasking optimization for the Android 13 kernel, mainly related to MGLRU (Multi-Generational Least Recently Used), that is, the multi-page recycling strategy, which is reported to greatly improve the situation that small memory mobile phones frequently kill the background.
Xiao Lei learned that Google has introduced this strategy in Chrome OS, which can effectively improve the situation that small memory devices are multitasking when running, due to high CPU occupation, the system accidentally kills background applications. According to Google tests, CPU usage was reduced by 40% with the help of the MGLRU strategy. In addition, a background manslaughter is reduced by 85% at 75% memory usage and 18% by render latency at 50% memory usage.
Kill the background for Android mobile phone users, it is normal, in the process of daily use, we often leave a lot of Apps in the background, such as the most commonly used QQ, WeChat, etc., to leave the application in the background, the purpose is to be able to quickly open it when it is needed, without a long cold start.
Generally speaking, the memory is relatively small mobile phones, the background residency ability is relatively poor, the user just hung in the background of the application, may not be long by the system "killed", so in the eyes of consumers, the larger the running memory of the smart phone, the better to use, or the more durable, and manufacturers often at the press conference will be the mobile phone application retention as a publicity point.
Nowadays, the running memory of the Android camp has also been further upgraded, and the low-end models have achieved 8GB starting, and some game phones are even equipped with 18GB. Unfortunately, even if it is a 12GB storage Android phone, the background residency capacity may not be as good as the 6GB iPhone, Xiao Lei believes that the background management strategy of iOS is very good, the large game hanging in the background on the same day, after two days can also do hot start.
Many netizens said that this is a unique "fake background" mechanism of iOS, no matter what, Xiao Lei hopes that the Android system can also improve the efficiency of running memory, do not let large memory become a decoration. As for the domestic custom ROM, it may not necessarily copy the kernel code of Android 13, but changes such as Google are also beneficial to manufacturers to optimize the background strategy, and consumers do not need to blindly pursue large memory mobile phones.
There is less than a month to go before the Google I/O conference, not surprisingly Google will announce the latest Android 13 system at the conference, and enter the beta testing stage, Xiaomi, OPPO, etc. also have the opportunity to become the first to eat the new system of the manufacturers.
