Why does Xiaomi's mobile phone become fast in power consumption and serious in fever after upgrading to 10.4.2.0?

First of all, Xiaomi's mobile phone has a serious fever, which is a common problem, especially when charging. Because of the charging of Xiaomi, Qualcomm's scheme is used. Qualcomm's solution does not support low-voltage fast charging, so it will be very hot to charge the mobile phone, and it is impossible to play games while charging. Another is the processing chip of Xiaomi mobile phone. Except for Qualcomm 855, almost all chips with the wavelength of 10 nm have high power consumption. The charging scheme is also relatively backward. This common problem may be solved next year, and some new mobile phones will follow Huawei's footsteps and use 7-nanometer chips.

Hello, I also use Xiaomi mobile phone. Let me talk about my power saving skills, hoping to help you.

First, manually turn off the message push and automatic update of all software. Only some commonly used softwares are pushed, such as QQ, WeChat, Weibo and so on. The advantage of this is that the background does not receive push messages and send them to you. Some infrequently used software will always push you some news that you won't read almost every day. When you turn this off, your mobile phone will be quiet and the information will not disappear. But every time you open the software, it will be displayed in the message on the software page. Can save a lot of traffic and electricity. (Believe me, this setting is very important)

Two: Turn off Bluetooth and GPS, and turn them on when using.

Three: use it when you are used for habitual charging, and don't wait for the red battery to run out. Don't always worry about the impact of total charging on battery life. If the battery is exhausted, charging will do more harm to the battery.

Four: In Xiaomi's own cloud service, turn off the option that does not need to be backed up. If you don't need cloud backup, you can turn it off completely. I just set the address book as a cloud backup and turn off everything else in the album, because I can manually operate these things at any time if I need to back it up. If I turn on automatic backup, it will consume electricity and traffic.

Five: The fewer turn-on functions, the faster the mobile phone and the more power-saving. For example, I unlock, fingerprint and face lock, I only use one, and I don't need to unlock with my fingerprint.

Six: the screen brightness is adjusted to 65%-75% for daily use, and it feels just right. Playing games without explanation, brightness 100%, especially stimulating the battlefield.

Seven: Regarding the dual card problem, if there is a backup machine, try to stand by with a single card. In the case of dual cards, the secondary card or the primary card should close the flow of one card as much as possible. In the case of dual card and dual 4G, the power consumption is still obvious.

Eight: Because many people habitually press the button to return to the main interface of the mobile phone after using an application, it will be faster and more convenient to enter the application next time, but you should know that more and more application backgrounds will always run, which will greatly reduce the battery life of the mobile phone. Operating Steps: Menu key-Call up background running program-Close.

Nine: Try to choose the officially recommended theme or the default theme. Select static wallpaper. Because many third-party topics are not good at actually optimizing compatibility. Dynamic wallpaper also consumes power.

Ten: It is forbidden to start the application by itself. I believe everyone knows that some applications always start automatically and consume a lot of power. You can find the self-starting application in the "security center"-"authorization management" in Xiaomi's mobile phone, and you can shut it down by yourself as needed. I basically banned it, leaving only one WeChat.

Eleven: downgrade to MlUl9.

I have sorted out eleven kinds of small methods, hoping to adopt them.

Xiaomi mobile phone battery is too small.

It should be a system optimization problem. Miui has always had many bugs. It is recommended to wait for the next version to optimize, or brush back to the previous version yourself.

This is a problem of system optimization, and generally there is no need to upgrade the system.

It is suggested to use 360 mobile guards for optimization, shut down background processes and start software to reduce power consumption.
