Definition & How It Works
A RAM booster (or memory cleaner) is a tool—found in System Monitor and CPU Monitor—that frees RAM by closing background apps and cached processes you are not using.
What RAM boosting actually does
- It triggers Android to reclaim memory from idle background apps.
- The system then has more headroom for the app you are actively using.
Real benefits and limits
On modern Android, the OS already manages memory intelligently, so a booster will not magically speed up everything. Its genuine value is targeted: when a heavy game or editor stutters, clearing background apps can free the RAM it needs. Think of it as a manual tidy-up, not a permanent performance fix—and avoid “auto-clean” tools that kill apps you actually want running.
