iPhone Battery Draining Fast? 10 Fixes That Work
Few things are more frustrating than watching your iPhone battery percentage drop rapidly. Before buying a new phone or battery, try these proven fixes.
1. Check Battery Health
Lithium-ion batteries degrade over time.
-
Go to Settings > Battery > Battery Health & Charging.
-
If Maximum Capacity is below 80%, consider a battery replacement.
2. Identify Battery-Draining Apps
Some apps consume far more power than others.
-
Go to Settings > Battery.
-
Scroll down to see battery usage by app.
-
Uninstall or limit background activity for high-drain apps.
3. Disable Background App Refresh
Many apps refresh content even when you're not using them.
-
Go to Settings > General > Background App Refresh.
-
Turn it off completely or disable it for specific apps.
4. Reduce Screen Brightness and Auto-Lock
The display is one of the biggest battery drains.
-
Swipe down from top-right to adjust brightness.
-
Go to Settings > Display & Brightness > Auto-Lock and set to 1-2 minutes.
5. Turn Off Push Mail
Fetching emails constantly consumes power.
-
Go to Settings > Mail > Accounts > Fetch New Data (on iOS 18 and later: Settings > Apps > Mail > Mail Accounts > Fetch New Data).
-
Set to "Hourly" or "Manually" instead of "Push."
6. Disable Location Services for Unnecessary Apps
GPS tracking is a major battery drain.
-
Go to Settings > Privacy & Security > Location Services.
-
Change apps from "Always" to "While Using" or "Never."
7. Turn Off Haptic Keyboard Feedback
Apple notes that keyboard haptics can affect battery life.
-
Go to Settings > Sounds & Haptics > Keyboard Feedback.
-
Turn off "Haptic."
8. Enable Low Power Mode
This feature reduces background activity and performance to extend battery.
-
Go to Settings > Battery > Low Power Mode.
-
Or add it to Control Center for quick access.
9. Disable 5G When Not Needed
5G consumes more power than LTE or Wi-Fi.
-
Go to Settings > Cellular > Cellular Data Options > Voice & Data.
-
Select "5G Auto" or "LTE" instead of "5G On."
10. Update to the Latest iOS
Apple regularly releases updates that fix battery-draining bugs.
-
Go to Settings > General > Software Update.
-
Install any available updates.
Why Drain Is Worse Right After an Update or a New iPhone
After a major iOS update, or when you set up a new iPhone from a backup, the phone re-indexes photos, messages and files and re-downloads apps in the background. Battery life is often worse for the first day or two. Keep it on Wi-Fi and charging overnight, and judge battery life after that.
Check What Is Using the Battery in the Background
In Settings > Battery, the app list can show both screen time and background activity for each app (tap the list to switch views, depending on your iOS version). An app with a lot of background activity you didn't expect is a good candidate for turning off its Background App Refresh or location access.
Other Settings That Help
-
Always On display (iPhone Pro models from iPhone 14 Pro onward): Settings > Display & Brightness > Always On Display. Turning it off saves some power.
-
Weak signal: in areas with poor mobile signal the phone works harder to stay connected. Use Wi-Fi where you can, or Airplane mode with Wi-Fi on in places with no signal.
-
Restart the iPhone if one app or process seems stuck and the phone feels warm while idle.
When the Battery Needs Replacing
Apple says its batteries are designed to keep up to 80% of their original capacity after a set number of full charge cycles (500 for older models, 1,000 for iPhone 15 and later), under ideal conditions. If Battery Health shows a Service message, or the phone shuts down unexpectedly at a decent percentage, get the battery replaced by Apple or an authorised service provider. Avoid cheap unbranded batteries.
Fast battery drain is often caused by background app activity, location services, or an aging battery. Start with Battery Health and app usage data, then apply the fixes that address your specific problem areas. Using an Android phone instead? See battery draining fast on Android.
Frequently Asked Questions (FAQ)
Why is my iPhone battery draining so fast all of a sudden?
Common causes are a recent iOS update still finishing background work, one app misbehaving, poor mobile signal, or an aging battery. Check Settings > Battery for the app list and Battery Health.
When should I replace my iPhone battery?
When Battery Health shows a Service message, Maximum Capacity is around or below 80%, or the phone shuts down unexpectedly. Use Apple or an authorised service provider.
Does Low Power Mode hurt my iPhone?
No. It only reduces background activity and some visual effects while it is on. It turns off automatically when the battery is charged enough.
Does closing apps save battery on iPhone?
Generally no. Apple doesn't recommend force-closing apps to save battery; only close an app that is frozen or misbehaving.
