Disable Zram Magisk Patched

This post shows two safe methods to disable zram on Android devices with Magisk installed: (A) a Magisk module that disables zram at boot, and (B) a one-line init.d-style script injected via Magisk. Use method A if you want an easy reversible option; use B for minimal changes.

For a permanent solution that survives reboots, create a custom boot script managed by Magisk.

Before disabling it, it is important to understand what it does. acts as a swap space in physical RAM, which is compressed on the fly.

Open the Magisk app, navigate to , and delete or toggle off the zRAM disabler module.

There are three reliable ways to disable ZRAM using Magisk. Choose the one that best fits your technical comfort level. disable zram magisk

Long-press the disable_zram.sh file in your root file manager and open its .

This handles the information shown in the Magisk app. Open a text editor and fill it with:

Inside, a simple post-fs-data.sh script:

#!/system/bin/sh # Script to disable zRAM systemlessly via Magisk # Give the kernel time to initialize zRAM before disabling it sleep 20 # Turn off swap space on zRAM device 0 swapoff /dev/block/zram0 # Reset the zRAM disk to clear allocated memory echo 1 > /sys/block/zram0/reset Use code with caution. Save the file. This post shows two safe methods to disable

#MAGISK

if [ -e "$ZRAM_DEV" ]; then # Disable the swap process on zram0 swapoff $ZRAM_DEV

Create service.sh (executes in background during boot):

Without zRAM, the system may aggressively kill background apps (OOM kills) once physical RAM is full. Battery Life Can slightly extend battery life by reducing CPU load. Hardware Health Before disabling it, it is important to understand

For high-end devices with , zRAM is often unnecessary. Disabling it frees up CPU cycles and uses raw, uncompressed physical RAM for optimum performance.

Higher CPU utilization during memory swapping translates directly to increased power consumption.

This feature functions as a "systemless" override. Instead of modifying files directly, Magisk injects a script that runs at post-fs-data mode to swap off the zRAM device. Core Implementation Logic

If you have a rooted device with , disabling ZRAM is a precise and reversible process. This article will walk you through everything you need to know about ZRAM, why you might want to disable it, and step-by-step methods to turn it off using Magisk modules, terminal commands, or custom scripts.
