The conditions for powering on and lighting up the screen:
1. The room temperature is 25℃(ambient temperature) ;
2. Use the original charger and charging cable to ensure that the device receives the proper voltage and current for an efficient startup.
Here are several factors that cause this problem:
1. When the phone's battery is at zero percent, especially after being in a long-duration low-power shutdown, the battery experiences low voltage;
2. Low battery voltage caused by scenarios such as triggering the low-temperature extended standby mode can affect the normal operation of this function.
The phone will eventually power up once enough charge is available.
