issues with phone

That rapid drop usually means the battery needs recalibrating, or it might be reaching the end of its lifespan. You can try wiping the cache partition or checking your battery health in the Samsung Members app.

We apologize for the inconvenience you are experiencing with your device's battery percentage dropping rapidly once it reaches 15%, even after reconnecting and disconnecting the charger.
To help identify the cause, we recommend trying the following steps:

1. Restart your device and check whether the issue persists.
2. Navigate to Settings > Device Care > Battery and review the battery usage details.
3. Check for available software updates through Settings > Software update > Download and install.
4. Update all installed applications through Galaxy Store and Google Play Store.
5. Open Samsung Members > Support > Phone Diagnostics > Battery Status to check the battery condition.
6. If the issue persists, we recommend visiting your nearest authorized Samsung Service Center for further battery inspection and assistance.
