If the notification bar shows that the Smart Charging Protection is enabled, it means the charging stops when the battery level reaches the set threshold for protection. This is to prevent frequent charging cycles and protect the battery. Charging will automatically resume when the battery drops below a certain level.
For your reference, here are some information about Charging protection:
1. Regular charging:
You can go to [Security] >> tap [Battery] >> go to [Battery protection] >> choose [Regular charging] which always charges up to 100%;
2. Optimized charging:
Adjust charging based on usage scenarios;
3. Battery protection:
To extend battery life, the device will stop charging when battery level reaches 80%.
