Editor's Overview

SaverTuner is a battery application developed by S1m, packaged as a single Android APK of version 1.1 weighing in at 1.67 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 1.67 MB, so it installs quickly even on modest connections.
  3. This build is signed by "S1m" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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: https://github.com/tytydraco/Buoy.
It adds support for Android 12+, save and restore profiles and improves the settings tiles.

Note that this app requires the WRITE_SECURE_SETTINGS permission that can be granted with EITHER a PC using ADB or root. Root is NOT required for this app, it is optional. Android 8.0+ is supported, with more features enabled on Android 10+.

Uninstalling the app will not reset the battery saver configuration. You must set the Default profile to undo all changes before uninstalling.

Features:
- 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

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.

Frequently Asked Questions

Is SaverTuner free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does SaverTuner require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is SaverTuner safe to install?
We link to the exact APK published by S1m. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update SaverTuner?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
