Ultimate Guide to Disabling zRAM via Magisk zRAM is a Linux kernel feature that creates a compressed block device in physical RAM. While it expands usable memory by compressing background processes, it introduces continuous CPU compression overhead. This can cause micro-stutters during heavy gaming and accelerates battery drain.

For users with high-capacity devices (8GB+ of RAM), zRAM is often redundant. On these devices, the performance cost of compression outweighs the benefit of extra space. By disabling zRAM, the kernel is forced to use the "raw" RAM. This results in:

, a compressed RAM-based swap device. While designed to improve multitasking on low-memory devices, many enthusiasts choose to disable it on modern smartphones using
