Why is the POCO X7 Pro unable to power on after the battery is low?

The POCO X7 Pro is equipped with a 6000mAh ultra-large battery, so the charging time will be extended. Sorry for the inconvenience caused to you! The battery management system needs to detect a sufficient voltage before it allows the phone to turn on. After the battery is low, it takes about 10 minutes to activate the screen before the icon will appear, and the battery voltage must meet the conditions before it can be turned on.
If this happens frequently, it can be a good idea to avoid letting your battery drain completely. It's better for the overall health of the battery and ensures your phone stays functional when you need it.
