Disabling ZRAM on a rooted Android device using Magisk is a powerful tweak for users who prioritize raw CPU performance over aggressive background app retention. The best method depends on your technical comfort level:
Leaving zRAM enabled on a high-spec device can introduce unnecessary bottlenecks:
ZRAM is a feature of the Linux kernel (which powers Android) that creates a compressed block device inside your RAM. When your system runs out of physical memory, it compresses old or less-used pages and stores them in this ZRAM space instead of writing them to the slower internal storage (swap file).
ZRAM creates a compressed block device in RAM that functions as swap space. When the system runs low on memory, it moves inactive pages into this compressed area, effectively increasing usable RAM at the cost of CPU cycles required for compression and decompression. disable zram magisk
zRAM is a standard feature in modern Android devices that acts as a compressed swap space inside your device's Random Access Memory (RAM). When your system memory fills up, Android compresses background apps and moves them into this designated zRAM block rather than closing them entirely.
: If your phone already features 12GB or 16GB of high-speed LPDDR5X RAM, you are highly unlikely to exhaust your physical memory. On these devices, zRAM introduces unnecessary processing latency with zero practical benefit. Why Use Magisk to Disable zRAM?
The terminal returns an empty output or shows no lines containing /dev/block/zram0 . Disabling ZRAM on a rooted Android device using
The processor no longer cycles through compression algorithms.
How to Disable zRAM via Magisk: A Complete Guide for Android Power Users
To disable zram using Magisk, you'll need to: ZRAM creates a compressed block device in RAM
The processor constantly spends cycles compressing and decompressing background data, which can cause micro-stutters.
If your device feels unstable or apps crash too frequently after disabling ZRAM, your device likely relies heavily on it due to low physical RAM ( /data/adb/service.d to revert the changes.
