If your iPhone 8 Plus is suddenly burning through battery after a recent iOS update—or even just in day-to-day use—you’re not alone. Battery drain is one of the most common iPhone complaints and often traces back to settings, apps, or software bugs. The good news? You can take control of it with a few practical tweaks.
1. Adjust These Key Settings to Save Battery Life
🔅 Lower the Screen Brightness
- Go to Settings > Display & Brightness
- Enable Auto-Brightness or manually drag the slider down
🌅 Turn Off Raise to Wake
- Go to Settings > Display & Brightness
- Toggle Raise to Wake OFF
📡 Disable Background App Refresh
- Go to Settings > General > Background App Refresh
- Select Off or Wi-Fi only
📍 Limit Location Services
- Go to Settings > Privacy > Location Services
- Set most apps to While Using or Never
🕵️♀️ Turn Off Motion & Dynamic Effects
- Go to Settings > Accessibility > Motion
- Enable Reduce Motion
- Go to Settings > Wallpaper and avoid dynamic wallpapers
2. Switch to Low Power Mode
This feature disables nonessential features when battery is low:
- Go to Settings > Battery
- Toggle Low Power Mode ON
Your battery icon turns yellow when active. It pauses email fetch, background app refresh, visual effects, and more to save juice.
3. Check Battery Usage Stats
- Go to Settings > Battery
- Review which apps are using the most power
- Delete or restrict background activity for apps like Facebook, Snapchat, or mail clients that use excess power
4. Disable Wireless Features When Not in Use
🛑 Turn off Wi-Fi, Bluetooth, and Mobile Data
- Swipe up to access Control Center
- Turn off anything you don’t need
📡 Prefer Wi-Fi Over LTE – it’s more power-efficient.
5. Restore iOS or Roll Back a Bad Update
If the battery drain started after an iOS update:
✅ Try a Restore via iTunes
- Backup your iPhone
- Connect to a computer and choose Restore iPhone in iTunes
🛠 Try Recovery Mode Restore or DFU Mode
- For stubborn battery bugs, use DFU mode to clean install iOS
- Visit your troubleshooting portal for DFU mode instructions if needed
6. Wait 24–48 Hours After Updating
Battery life often suffers briefly after an iOS update as the system reindexes files and background tasks complete. Give it 1–2 days before deciding it’s a long-term issue.
