My Android phone (OnePlus 9) is slowing down after a year. Any tech hacks to boost performance without a factory reset? Cleared cache, uninstalled apps, still laggy. Also, is rooting worth it in 2025?
Android Hacks for Better Performance
Hi SpeedFreak99,
From a security perspective, there are several effective ways to improve your OnePlus 9 performance without resorting to a factory reset.
-
Check for resource-heavy apps running in the background using Developer Options (Settings > About Phone > tap Build Number 7 times > go back to Settings > Developer Options > Running Services)
-
Disable or restrict unnecessary background processes and animations:
- Settings > Battery > Battery Optimization
- Settings > Developer Options > Drawing > reduce animation scales to 0.5x
-
Update your system and apps - OnePlus often releases performance patches
-
Use storage analyzer tools to identify large files/apps consuming space
-
Consider a lite launcher like Nova Launcher which consumes fewer resources
Regarding rooting in 2025 - it’s rarely worth the security trade-offs for performance gains. Modern Android is optimized enough that rooting primarily compromises your device security while offering minimal performance benefits.
If performance issues persist despite these steps, it might be worth checking if any monitoring apps are running in the background consuming resources.
Here’s how you can fix this without going nuclear with a factory reset:
Developer Options tweaks: Enable Developer Options (tap Build Number 7 times in About Phone). Set Window/Transition/Animator scale to 0.5x or off completely - makes everything feel snappier. Also disable animations you don’t need.
Storage optimization: Use your phone’s built-in storage analyzer to find large files you’ve forgotten about. Videos and photos are usually the culprits. Move them to cloud storage or external storage.
Background processes: Go to Settings > Battery > Battery Optimization and restrict background activity for apps you don’t need running constantly. Social media apps are notorious resource hogs.
Thermal throttling: OnePlus phones can throttle when they get warm. Check if your phone feels hot during lag spikes - might need a case with better ventilation or avoid heavy usage while charging.
About rooting: In 2025, it’s less necessary than before. Modern Android handles RAM and processes much better. Unless you need specific root-only features, the security risks usually outweigh the performance gains. Try these other fixes first.
