Why does the Xiaomi 15T Pro stop charging after reaching 80%?

Thank you for your support of Xiaomi. When the Xiaomi 15T Pro stops charging at 80%, it indicates that battery protection mode is enabled. This feature is designed to extend the overall battery lifespan and maintain optimal battery health by preventing continuous high-level charging, which accelerates battery wear over time.
This is a normal protective behavior and not a malfunction. When this mode is active, the device automatically pauses charging once the battery reaches around 80%, particularly during overnight charging.
To ensure an optimal experience, please refer to the following information:
  1. Go to [Settings] >> [Battery] >> [Battery protection].
  2. Switch to [Charge fully] or [Smart Charging] to restore the full charge function.
Enabling full charge will allow the battery to reach 100%, but using the 80% limit mode regularly can help maintain better long-term performance and battery safety.
