2. Wipe Cache Partition
After an update, a damaged cache may result in excessive battery consumption. One secure method to fix this without erasing sensitive information is to wipe the cache partition.
How to Wipe Cache Partition:
- Turn off your Galaxy device.
- Connect it to a computer via USB.
- Hold Power + Volume Up until the Samsung logo appears.
- Use the volume buttons to highlight “Wipe cache partition” and press Power.
- Confirm and reboot.
3. Update All Apps
Older apps might not be One UI 7 compatible. To guarantee compatibility and effectiveness, update every app from the Google Play Store and Galaxy Store.
4. Check Battery and Location Settings
- To find out which apps use the most power, navigate to Settings > Battery & Device Care > Battery.
- Limit background activity for apps that use a lot of resources.
- For apps that do not require continuous access, check location permissions and turn off “Allow all the time.”
5. Use One UI 7 Battery Protection Features
One UI 7 introduces new battery protection tools:
- Adaptive Mode: Limits charging to 80% overnight, topping up before you wake.
- Maximum Mode: Set a custom maximum charge (80%, 85%, 90%, 95%) to extend battery lifespan.
- Auto Dim Screen: Automatically dims the display when battery drops below 5%.
Access these in Settings > Battery > Battery Protection and Settings > Display > Auto Dim Screen.
6. Factory Reset as a Last Resort
If other solutions fail, a factory reset can resolve persistent battery drain. Back up your data before proceeding.
