SaverTuner

SaverTuner

Extension to the built-in Android Battery Saver

Description

Android's built-in battery saver can be set quite finely. However, it is not configurable out of the box. SaverTuner allows you to take advantage of this built-in battery saver. You can now set different profiles that save the battery more or less aggressively. From a daily optimization that does not affect performance to an extreme optimization that saves power as much as possible.

This application is based on Buoy. It adds support for Android 12+, save and restore profiles and improves the settings tiles.

Features

It uses hidden Android settings to specify custom behavior for the built in battery saver. Features include the following toggles:

Advertising to other apps that low power mode is enabled

Android's data saver for metered WiFi or mobile data connections

The built-in dark mode

Launch boost to accelerate app starts

Vibration

Showing window and activity animations

Allowing apps to use the SoundTrigger HAL

Deferring full device backups for later

Deferring app setting backups for later

Using the built-in web firewall to protect against possibly malicious sites

Changing the location access mode restrictions for apps

Reducing the max brightness of the panel

Forcing all apps into standby mode

Forcing all apps to not check data in the background

Disabling unnecessary sensors

Using the Always-On-Display

Putting the device into deep sleep as soon as the screen turns off

Sticky Low Power

It also enables something called "sticky" low power mode. Usually, when the device is plugged in and unplugged, the low power mode is then disabled. However, sticky mode re-applies low power mode afterwards to continue saving battery.

Disclaimers
