How to Speed Up a Slow Android Phone
By Site Editor · Updated September 13, 2026 · 9 min read
Android phones slow down over time — storage fills up, apps multiply, and background processes pile up. These steps bring most phones back to a noticeably faster state.
1. Free up storage space
Android performance degrades when internal storage is nearly full. Go to Settings → Storage to see what is taking up space. Delete photos and videos you have already backed up, clear app caches (Settings → Apps → select an app → Storage → Clear Cache), and uninstall apps you no longer use.
2. Limit background app activity
Settings → Apps → see all apps. For apps that do not need to run in the background, tap the app → Battery → choose Restricted. This prevents them from waking the CPU unnecessarily. Social media and news apps are common background-process offenders.
3. Reduce or turn off animations
Enable Developer Options by going to Settings → About phone and tapping Build number seven times. Then go to Settings → Developer options and set Window animation scale, Transition animation scale, and Animator duration scale all to 0.5× or off. The phone will feel noticeably snappier even if no actual speed has changed.
4. Install system and app updates
Settings → System → Software update. Manufacturers regularly release patches that improve performance and fix memory leaks. Also open the Play Store → your profile icon → Manage apps and device → Update all to ensure all installed apps are current.
5. Factory reset as a last resort
If nothing else works, a factory reset returns the phone to its out-of-box state. Back up photos to Google Photos, contacts to your Google account, and note which apps you need. Then go to Settings → General management → Reset → Factory data reset. The phone will feel like new after the reset and a fresh app install.
Frequently asked questions
Does closing background apps speed up Android?
Rarely. Android manages background apps efficiently. Force-closing them can actually slow things down because apps have to fully reload next time. Focus on storage and limiting which apps run in the background instead.
How much free storage should I keep on Android?
Keep at least 10–15% of storage free. Most phones show a warning at 15% — do not wait until you reach that level.
Will a factory reset make my phone faster?
Yes, in most cases. It removes accumulated junk, corrupted caches, and poorly optimised app configurations. It is the most thorough fix but also the most disruptive.
