Thank you for your support of Xiaomi products, and sorry for the trouble caused to you. The POCO F7 Pro is equipped with a 6000mAh ultra-large battery, so the charging time will be extended. The phone can only be turned on when the battery voltage meets the conditions. After the battery is out of power, at least 10 minutes of charging is required to activate the screen before the icon appears.
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.
