Power Saver Pro is an open-source Magisk module designed to extend Android battery life without touching core system files. It adjusts background task limits, tunes CPU frequencies, and enforces aggressive deep sleep states to stop idle battery drain directly at the root level.

After flashing this module on a custom ROM, my standby battery drain dropped from around 8% overnight to barely 2%. The device enters deep sleep almost immediately when locked, without causing noticeable delays in messaging app notifications.

Core Features

Aggressive Doze: Forces the phone into deep sleep seconds after turning off the screen.
Governor tuning: Automatically lowers CPU clock speeds during basic tasks like reading or texting.
Wakelock blocking stops rogue background services and telemetry from waking up the processor.
Memory cleaner: Periodically trims cached background data to keep RAM free and reduce power draw.

Support & Requirements

Android Version: Android 9.0 (Pie) to Android 15
Root Manager: Magisk v24.0+, KernelSU, or APatch

How to Install

Download the latest Power Saver Pro .zip file to your internal storage.
