Extreme Battery Saver

Extreme Battery Saver is a systemless Magisk module designed to extend Android battery life by strictly managing background processes and hardware power consumption. It controls CPU frequencies, limits non-essential background activity, and reduces screen power draw to maximize screen-on time.

I’ve been running this on my daily driver, and the overnight idle drain dropped to virtually zero. By throttling the CPU during light tasks and automatically freezing rogue background apps, my phone stays noticeably cooler without lagging during normal use.

Core Features

• Smart CPU limiters scale down processor speeds during simple tasks to prevent unnecessary heating.
• Freezing background junk happens automatically, ensuring your main notifications arrive while resource-heavy apps get shut down.
• Display power draw drops efficiently through an automated system-level screen dimmer.

Support & Requirements

• Supported Android: Android 8.0 and above
• Root Type: Magisk or KernelSU required

How to Install

1. Download the Extreme Battery Saver .zip file and open your Magisk or KernelSU manager.
2. Navigate to the Modules section, tap "Install from storage," and select the downloaded file.
3. Reboot your device to activate the new battery parameters.
