SaverTuner, an open-source Android app, enhances battery life by utilizing Android's system power profiles and CPU controls without aggressive tactics.
Functionality and Features
Unlike typical battery apps, SaverTuner optimizes battery use through tailored profiles that modify system behaviors. Users can choose from profiles like Light to Extreme optimization, with each profile detailing changes such as data saving, launch boost, and display adjustments. The app reduces overnight standby drain significantly—from 8-12% to 5-6%.
- Requires no rooting, but ADB permission is needed.
- Profiles adjust brightness, control app standby, and limit service checks.
- SaverTuner stops unnecessary sensors and manages Always-On Display.
SaverTuner offers ease of use by automatically stepping aside after configuration, ensuring minimal system impact.
Setup and Usage
No root access is required for SaverTuner, but users must enable WRITE_SECURE_SETTINGS through ADB. This is done by:
- Enabling Developer Options and USB debugging.
- Connecting the phone to a PC.
- Executing: adb shell pm grant --user 0 s1m.savertuner android.permission.WRITE_SECURE_SETTINGS
After setup, the app operates silently, with profiles maintaining system efficiency.
When removing SaverTuner, users should manually revert to default settings to ensure smooth battery performance.
