Lower RAM Usage in Realme C3 for Smooth Gaming & Multitasking

Device: Realme C3 (RMX2020)
Type: Magisk Module (Systemless)
Version: 1.0

This Magisk module helps reduce overall RAM usage by optimizing Android's heap configuration — specifically by adjusting heapstartsize, heapgrowthlimit, and heapsize.

What is a Heap and Why It Matters

In Android, the heap is a section of memory allocated to apps for storing runtime data such as objects, variables, and resources.

  • heapstartsize: This defines the initial memory allocated to an app when it starts. A lower value helps reduce RAM usage at launch, which is helpful for lightweight apps.
  • heapgrowthlimit: This limits how much the heap is allowed to grow. Tuning this helps prevent apps from consuming too much memory over time.
  • heapsize: This sets the maximum heap size an app can use. Keeping this controlled ensures better memory distribution across multiple apps.

By modifying these values, the module improves memory management, leading to smoother multitasking and less lag during gaming — especially on devices like the Realme C3 that have limited RAM.

What Does "Systemless" Mean?

Systemless means that the module modifies the behavior of your device without altering the system partition. Instead, it uses Magisk’s overlay system to apply changes during boot. This keeps the system intact, making it easier to pass SafetyNet, revert changes, or update your device safely.

Compatibility Notes

  • Device: Only tested on Realme C3 (RMX2020)
  • Android Version: Optimized for Android 10 and 11
    (May work on other versions, but not guaranteed)
  • Root Required: Yes (Magisk must be installed)
  • Magisk Version: Recommended Magisk v21.0+

Disclaimer

  • Use at your own risk. This module modifies memory management behavior, which may not be suitable for all users or devices.

  • Do not flash this module on unsupported devices to avoid potential issues.
