What is the function of charging suspension protection on the Xiaomi 15 Ultra Photography Kit?

The function of charging suspension protection means when the battery level of the phone is higher than 80%, and the battery level will not increase (displaying the charging icon), the phone will consume the power of the photography kit as the priority, keep the phone power not changing, and extend the battery life.
Note:
1. With a massive 2000mAh (typ) battery, the grip can also be used as a power bank, allowing you to shoot for longer. It also supports charging your smartphone without removing the grip;
2. By default, the photography grip can charge the phone when the phone’s battery is under 20% and can be customized in settings.
