iPhone Battery Draining Fast in 2025? 12 Proven Fixes to Improve Battery Life
If your iPhone battery is draining fast, you’re not alone. Millions of iPhone users reported major battery drops in 2025 due to new background features, AI-powered apps, and higher refresh rates. While modern iPhones are powerful, the increased performance leads to faster battery consumption — especially on devices with older batteries.
Many users report their iPhone battery draining fast, especially after recent iOS updates and heavy background activity.
The good news? You can fix most battery drain issues without replacing your iPhone. In this guide, you’ll learn 12 proven fixes to extend your battery life and prevent rapid draining throughout the day.
1. Check Why Your iPhone Battery Is Draining Fast
Go to Settings → Battery and look at:
- Apps using the most power
- Background activity
- Screen on vs screen off usage
- Battery health percentage
If you see certain apps consuming 20–40% alone, they are the main cause behind your iPhone battery draining fast.
2. Turn Off Background App Refresh
Many apps refresh content constantly.
Fix:
Settings → General → Background App Refresh → Turn off for unnecessary apps.
This instantly reduces battery drain by 10–20%.
3. Enable Low Power Mode
Low Power Mode limits background activity, mail fetch, 5G usage, and visual effects.
One of the biggest reasons for an iPhone battery draining fast is constant background refresh from social media and messaging apps.
Fix:
Settings → Battery → Low Power Mode (ON)
Use it throughout the day for maximum battery savings.
4. Reduce Screen Brightness
Your display consumes the most energy.
Fix:
Swipe down → Lower brightness
Or enable Auto-Brightness under Accessibility.
Keep your screen below 50% whenever possible.
5. Turn Off 5G When Signal Is Weak
5G uses more power when your signal is unstable.
If your iPhone battery is draining fast, lowering screen brightness and disabling unnecessary location services can help immediately.
Fix:
Settings → Cellular → Voice & Data → LTE
Switching from 5G to LTE can reduce battery drain significantly.
6. Disable Unnecessary Location Services
Apps don’t need to track your location all day.
Fix:
Settings → Privacy → Location Services
Set most apps to While Using instead of Always.
7. Limit Notifications
Every notification wakes up your screen.
Fix:
Settings → Notifications → Turn off for apps you don’t need.
This alone helps greatly if your iPhone battery is draining fast even in idle state.
8. Update iOS to the Latest Version
Apple patches battery issues often.
Fix:
Settings → General → Software Update
Install the latest version.
Some iOS updates dramatically improve battery performance.
9. Clear Safari and App Cache
Heavy cache files slow down performance and increase battery usage.
Fix:
Safari → Clear History and Website Data
Apps → Offload unused apps
Reinstall apps with excessive storage
10. Restart Your iPhone Regularly
Restarting clears system bugs that cause overheating and battery drain.
A simple reboot every 2 days helps refresh your system.
11. Reduce Heat Exposure
If your phone overheats, your battery drains faster.
Avoid:
- Leaving your phone in the sun
- Charging while gaming
- Using thick cases during heavy tasks
Heat directly damages battery health over time.
12. Reset All Settings (Last Resort)
This won’t delete your data, only system settings.
Fix:
Settings → General → Transfer or Reset iPhone → Reset All Settings
This fixes many hidden issues causing iPhone battery draining fast on iOS 17+.
When Should You Replace Your Battery?
Check Battery Health under Settings → Battery.
If it’s:
- 85–90%: mild degradation
- 80–85%: noticeable drain
- Below 80%: replace battery recommended
Apple considers 80% the official “degraded” threshold.
