The Xiaomi Pad 7 Pro limits its charging to 80% due to the charging protection function, which is designed to preserve the long-term health of the battery. Charging to 100% regularly can cause increased wear on the battery over time, reducing its lifespan. By limiting the charge to 80%, this function helps mitigate this effect, maintaining battery health for a longer period.
If you prefer to charge your device fully, you can turn off the charging protection by referring to the steps:
1. Open the [Settings] APP on your device;
2. Scroll down and tap [Battery];
3. Select [Battery protection];
4. Turn off [Limited charging].
