Quick answer: To speed up a slow phone, restart it, update the system and apps, free storage, remove unused apps, limit background apps and animations, and test in safe mode to find a bad app. Avoid “booster” apps. If it stays slow, the battery or storage may be failing. Junaid Telecom, Chiniot: WhatsApp 0345 7599995.
First, what kind of slow is it?
- Slow all day, every day: often full storage, an old phone with new heavy apps or a failing battery.
- Slow only after some hours: a runaway app or heat.
- Slow after an update: the phone may still be optimising.
- Slow only in one app: problem with that app, not the phone.
- Hangs, freezes and reboots: may be hardware.
10 safe tips, in order
1. Restart the phone
It clears temporary glitches and stuck processes. Make it a weekly habit. This is the cheapest fix and often the best one.
2. Check free storage
When storage is nearly full, phones slow down because the system cannot work properly. Follow our guide to free up storage. Aim for 10 to 15 percent free.
3. Update the system and apps
Updates carry bug fixes and performance improvements. Use Wi-Fi, keep the battery charged and take a backup first. If the phone gets no more updates, be careful about installing the newest heavy apps.
4. Remove or disable apps you don’t use
Uninstall old games, duplicate apps and ones you installed for a single occasion. For built-in apps that can’t be removed, disable them or stop background activity.
5. Limit background activity and auto-start
Apps that start with the phone or refresh in the background use memory and processing. In Settings > Apps or Battery, restrict those you rarely open. But don’t restrict messaging apps you need for alerts.
6. Reduce animations (Android)
If you enable Developer options (tap the build number several times in About phone), you can set window animation, transition animation and animator duration scales to 0.5x or off. The phone feels quicker even though the hardware is unchanged. Only change these three settings.
7. Use lighter app versions
For older phones, lite versions of social apps and browsers run more smoothly. Also reduce widgets and live wallpapers.
8. Clear the cache of heavy apps
Clear the cache of your browser and heavy social apps if they act up. Avoid “Clear data” unless you are ready to log in again and lose local settings.
9. Test in safe mode
Safe mode disables third-party apps. The method differs by phone, but typically involves pressing and holding the power-off option and confirming. If the phone is fast in safe mode, one of your apps is the cause. Remove recently installed apps one at a time.
10. Factory reset as a last resort
If it is still slow after everything and you can’t find the cause, a reset can help, since it clears accumulated junk. Back up everything first and note your account passwords. After the reset, install only the apps you need, and check performance before restoring everything. A reset will not fix a hardware fault.
What to avoid
| Don’t | Why |
|---|---|
| RAM boosters and “cleaners” | Mostly ineffective, often loaded with ads |
| Random “speed up” files from unknown sources | Security risk |
| Rooting or flashing unknown firmware to chase speed | Can void warranty, risk data and security |
| Closing all apps repeatedly | Forces reloads and uses more power |
| Ignoring a swollen or hot phone | Safety issue, see our swollen-battery post |
When the cause is hardware
Software tips cannot fix:
- A worn battery. Some phones slow down when the battery can’t supply power during peaks. See when to replace your battery.
- A failing storage chip. The phone freezes when saving or opening files, apps crash and the storage reading looks odd.
- Overheating. A phone that throttles from heat feels slow. See our heating guide.
- Water or drop damage that left a board fault.
A technician can check the battery and storage condition. Ask for the rate on WhatsApp, because it depends on the model and the fault.
Is it time to upgrade?
If your phone no longer receives updates, struggles with basic apps even after a clean reset and the battery and repair costs would be high, a newer phone may be sensible. Junaid Telecom also sells mobile phones; WhatsApp to ask what is available.
