I Tested 12 Ways to Speed Up an Android Phone — Which Ones Actually Worked?

QUICK ANSWER

Out of 12 common tips, the ones with a measurable effect were: clearing storage above 85% usage, disabling unused background apps, updating the OS, and removing bloatware. Tips like closing apps from the recent-apps screen and installing "booster" apps made no measurable difference or made things worse.

Why This Happens

Android's performance depends heavily on available RAM and free storage, since the OS reserves resources for caching and background services. When storage runs low, the system has less room to manage these processes efficiently, which is the most common reason average users notice sudden slowdowns.

Step-by-Step

1 Test 1 — Restart the device: freed up background memory immediately; noticeable improvement in app-open

speed.

2 Test 2 — Clear storage to below 80% usage: strongest overall improvement in the test, especially for

app-switching speed.

3 Test 3 — Disable unused background apps and permissions: moderate improvement, mainly in battery life and

standby smoothness.

4 Test 4 — Update the OS to the latest version: fixed occasional stutter caused by outdated

drivers/optimizations.

5 Test 5 — Uninstall pre-installed bloatware where possible: freed storage and reduced background processes.

6 Test 6 — Force-closing apps manually from recent apps: no measurable benefit; in some cases caused apps to

reload slower afterward.

7 Test 7 — Installing a third-party "cleaner/booster" app: no measurable benefit; added its own background

process.

8 Test 8 — Switching to a lighter home-screen launcher: minor improvement on older/low-RAM devices only.

9 Test 9 — Disabling animations in Developer Options: made the phone feel faster (perception) without changing

actual load times.

10 Test 10 — Clearing individual app caches: minor improvement, mainly for apps with large temp-file buildup like

browsers.

11 Test 11 — Turning off live wallpapers and widgets: minor battery and standby improvement, negligible speed

change.

12 Test 12 — Factory reset: largest single improvement, but only worth it if storage/cache cleanup didn't already

solve the problem.

Common Mistakes to Avoid

• Relying on booster apps instead of the phone's built-in storage and cache tools.

• Force-closing apps as a daily habit, which can increase reload time and battery use.

• Jumping straight to a factory reset before trying lower-effort fixes.

FAQ

Which single fix made the biggest real difference?

Freeing storage below 80% usage had the most consistent, measurable impact across the test.

Are booster apps worth installing?

Based on this test, no — they added background overhead without a measurable speed gain.

Does disabling animations actually speed up the phone?

It changes how fast the phone *feels*, not actual processing speed, but it's a legitimate low-risk tweak.

Conclusion

Real speed gains on Android come from storage management, background-app control, and software updates — not from booster apps or habitual force-closing. Start with the free, built-in tools before considering a reset.
