25 Fixes for iOS 18 Battery Drain
Every fix here targets a real reason for iOS 18 battery drain. If one does not help, skip ahead to the next. Stick with it and your device should last longer between charges.
1. Check Battery Health
Open Settings, tap Battery, then Battery Health. If the capacity is below 80 percent, the battery’s probably worn out. No fix will work well if the battery itself is too old. [Insert Screenshot]
2. Monitor Battery Usage
While in Settings > Battery, check which apps are using the most battery. If you see something unexpected, try deleting or limiting those apps. This shows where power is going, so you know what needs fixing. [Insert Screenshot]
3. Restart Your Device
After updates, tiny bugs can run in the background. Hold down the power and volume buttons, slide to turn off, and power back on. This simple step often clears out glitches that make battery drain worse.
4. Update All Apps
Old apps do not always work well with new iOS. Open the App Store, tap your profile, and choose Update All. This ensures every app is tuned for iOS 18, which can cut down on battery drain.
5. Enable Low Power Mode
Go to Settings > Battery and switch on Low Power Mode. This pauses some background tasks and limits things like mail fetch and downloads, giving you more hours from your battery instantly.
6. Turn Off Background App Refresh
Settings > General > Background App Refresh. Set it to Off, or just Wi-Fi. Apps can’t update quietly in the background, which saves power.
7. Limit Location Services
Settings > Privacy > Location Services. Pick “While Using App” or “Never” for apps that do not truly need your location. Fewer apps tracking you means more battery leftover. [Insert Screenshot]
8. Disable Unused Widgets
Hold any widget, tap Remove. Widgets like Weather or Maps update often, which can drain battery faster than you think.
9. Dim the Screen & Use Auto-Brightness
Settings > Display & Brightness. Lower the brightness or turn on Auto-Brightness. Brighter screens use more power, especially in sunlight.
10. Use Dark Mode
Settings > Display & Brightness > Appearance. Dark Mode usually uses less power, especially on devices with OLED screens.
11. Shorten Auto-Lock Time
Go to Settings > Display & Brightness > Auto-Lock. Set it to 30 seconds or a minute. Your screen will turn off faster when you are not using it.
12. Turn Off Raise to Wake
Settings > Display & Brightness > Raise to Wake. Turning this off means your screen does not turn on from every bump or move.
13. Disable Always-On Display (if available)
Settings > Display & Brightness. Always-On Display keeps some screen pixels active. If your iPhone supports this, turn it off for extra battery savings.
14. Turn Off Haptic Keyboard Feedback
Settings > Sounds & Haptics > Keyboard Feedback. Haptics make your phone vibrate each time you type. It feels nice, but it uses extra battery.
15. Disable Unnecessary Notifications
Settings > Notifications. Turn off alerts for apps that are not important to you. Fewer notifications mean less power wasted.
16. Stop Sending Analytics to Apple
Settings > Privacy > Analytics & Improvements. Turn off “Share iPhone Analytics.” When your phone sends less data, it saves energy.
17. Turn Off Apple Advertising
Settings > Privacy > Apple Advertising. Personalized ads use more resources. Turning it off gives a small boost to battery life.
18. Disable Automatic App Updates
Settings > App Store. Turn off App Updates. Update apps manually when you’re plugged in. This stops unwanted background activity.
19. Turn Off Sound Recognition
Settings > Accessibility > Sound Recognition. This feature keeps the microphone listening, which can drain battery even if you never use it.
20. Limit Siri Features
Settings > Siri & Search. Turn off “Listen for Hey Siri” and unnecessary Siri Suggestions. Siri is handy, but some options are power-hungry.
21. Reduce Motion and Animation
Settings > Accessibility > Motion > Reduce Motion. Fancy transitions are cool, but less animation means less work for your device, saving power.
22. Use Airplane Mode in Poor Signal Areas
If your phone struggles to find a signal, switch to Airplane Mode. When signal is weak, your device uses extra battery searching for service.
23. Reset All Settings (if issues persist)
Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This does not erase your data, but it resets system quirks from the update.
24. Use Only MFi-Certified Chargers
Always use Apple or MFi-certified chargers. Cheaper options can cause battery problems or slow down charging. Safe charging protects your device.
25. Don’t Let Your iPhone Overheat
Heat is a battery killer. Keep your phone out of hot cars and direct sun. High temperatures can cause lasting damage and faster battery drain.
