With zRAM disabled, the CPU no longer wasted cycles on unnecessary compression. The phone felt snappier, and Alex enjoyed a "buttery smooth" experience, proving that sometimes, less (virtual) RAM is actually more (performance).
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
He checked: free -h . Total RAM: 3.7GB. Used: 2.9GB. No swap.

On modern devices equipped with 8GB, 12GB, or 16GB of physical RAM, zRAM is often redundant and unnecessarily throttles peak performance. Prerequisites Before Proceeding
: If you have 6 GB of RAM or more and you’re not a heavy split-screen user, disabling ZRAM is safe and can improve raw performance.
He set permissions ( 0755 ) and added an empty module.prop : With zRAM disabled, the CPU no longer wasted
Open the app and grant it root superuser permissions when prompted. Navigate to the following directory: /data/adb/service.d/
Your device must be rooted with Magisk installed.
#!/system/bin/sh # Wait for the system to fully boot sleep 30 # Turn off swap/zRAM swapoff /dev/block/zram0 # Reset the zRAM disk size to 0 echo 1 > /sys/block/zram0/reset echo 0 > /sys/block/zram0/disksize Use code with caution. Step 3: Set Permissions Battery Life Can slightly extend battery life by
, which provide a "systemless" way to modify your device without permanently altering the system partition. Recommended Magisk Modules
If you are ready to experiment with your device's memory performance, let me know: What are you optimizing? How much physical RAM does your device have?
