Xiaomi mobile phones are optimizing the application startup speed, how can it not be turned on

First of all, you must be clear about why your phone does not turn on. There are two kinds of problems with the phone not turning on: hardware or software, and system.

If there is an external force, such as being dropped, pressed, flooded, overheated, etc., it must be a hardware problem. If you have some software, delete some system files, or can't boot after flashing, this is generally a software or system problem. Understand the problem** problem and solve it.

There are two situations in which the phone does not turn on, and the solutions are as follows. The phone turns on but doesn't turn on properly: This is the most common condition where the phone won't turn on.

When the phone is turned on, there is a vibration and sound, but the screen is dark; After the mobile phone is turned on, it has been stuck in the logo interface and cannot enter the operation interface; There is also the fact that the mobile phone can enter the normal interface but there is no response when you click on anything, etc., which is the most common manifestation of abnormal boot. First things first: check your phone's battery.

The reaction when the phone is turned on proves that the battery is still working, and in addition to the aging of the battery and water ingress, the battery problem can be ruled out. If the battery is aging, you can try it with the same type of battery, and if it can be turned on normally, then replace it with a battery; If it is water, turn on the device when the water has not yet dried, it will cause a short circuit in the battery, and the phone will only run for a while, and the battery will be damaged due to a short circuit, you can wait for a day or two for the phone to completely dry and change the battery. And then:

Check your phone screen. The screen fails under the destruction of external forces, especially some mobile phones themselves are soldered, which is particularly prone to the screen"Fake does not turn on"。Although only a slight fall, but the mobile phone screen is no longer responsive due to the disconnection of the line, at this time you can tap the phone, a few more shots, if the mobile phone screen will flash from time to time, this proves that the mobile phone is only a certain line of problems, you can disassemble the machine after finding the disconnected solder joint to re-weld, or go to the repair point for repair.

Especially when the phone vibrates and sounds normally when it is turned on, but the screen does not respond. This is especially the case for consideration. Again:

Check if you can enter the recovery, consider flashing. Both of the above are hardware problems, but the phone can't be turned on completely normally, because there are many software or system problems. If the phone is just stuck in the logo screen or can not be operated when booted into the interface, then check whether the phone can enter recovery, press and hold the power button + volume down key, if the phone enters the following screen, and can move the cursor by moving the volume + and - keys of the mobile phone, then the mobile phone can be solved by flashing.
