Why does the POCO X7 Pro not turn on when it is plugged into the charger?

Sorry for the trouble! The function of turning on the phone immediately after plugging into a charger when the phone is turned off is a zero-power-on function. It requires two prerequisites:
1. The phone must be charged to 1% or less before it is turned off and the battery cannot be in a dead state. Otherwise, the phone will enter the shutdown charging option when plugged into a charger after it is turned off;
2. Zero-power-on has different performances for different chargers. It is recommended to use the official standard fast charger to achieve zero-power-on function when the phone is turned off with less than 1% power;
3. If the phone has been turned off for a long time (such as a newly purchased phone), the phone battery can be in an out-of-power state. At this time, you need to charge the phone more often to turn it on.
