What is Xtreme Battery Saver?

Xtreme Battery Saver (XtremeBS) is a Magisk/KernelSU module designed for rooted Android devices. It provides aggressive battery optimization by controlling CPU cores, apps, WiFi, Doze mode, and more. With proper configuration, it can extend battery life up to five times longer than stock settings.

Requirements

A rooted Android device (Magisk or KernelSU confirmed compatible; APatch likely works).
Basic knowledge of editing configuration files.
Willingness to test and fine-tune settings.
Backup of your device before applying changes.

Features

App Management: Kill, suspend, or reprioritize apps using allowlists and denylists.
CPU Optimization: Put CPU cores into powersave mode or disable high-power cores.
System Tweaks: Force light/deep Doze, disable WiFi, enable low RAM mode, manage Google Mobile Services.
Event-Driven Control: Apply settings based on triggers like boot, charging, screen off, or low power.
Web UI & Commands: Configure via web interface or XBSctl commands.
Safety Features: Safe mode recovery and sanity checks to prevent crashes.

Why Use Xtreme Battery Saver?

Unlike standard battery saver apps, XtremeBS works at the system level, giving you deeper control over how your device consumes power. This means:

Longer screen-on time.
Improved standby efficiency.
Customizable profiles for different usage scenarios.

Download

You can download the latest release from the official GitHub repository.

It is also available via the Magisk Modules Alt Repo (MMRL).

Installation

Ensure your device is rooted with Magisk or KernelSU.
Download the module ZIP file.
Open Magisk Manager > Modules > Install from storage.
Select the downloaded ZIP.
Reboot your device.

How to Use

After installation, a default config file is created at /data/local/tmp/XtremeBS/XtremeBS.conf.
Edit the config manually or use the web UI (http://127.0.0.1:8081).
Reload the config with XBSctl reload or reboot.
Start with basic tweaks (like app management) before moving to aggressive options.
