2. Slide to turn off your iPhone.

3. Wait 30 seconds, then press and hold the Side button to turn it back on.

2. Check Battery Usage by Apps

Some apps may consume more power after an update, especially if they are not optimized for the new iOS version.

Steps:

1. Go to Settings > Battery.

2. Scroll down to see Battery Usage by App.

3. Identify apps consuming excessive battery.

4. Consider updating or reinstalling these apps.

This helps you spot iPhone apps draining battery unnecessarily.

1. Open the App Store.

3. Scroll down and tap Update All.

Regular updates ensure apps run efficiently and reduce iPhone battery issues.

Background app refresh allows apps to update content even when you’re not using them. Turning it off saves battery.

Steps:

1. Go to Settings > General > Background App Refresh.

2. Tap Off or choose Wi-Fi only.

This step significantly reduces unnecessary power consumption.

5. Reduce Screen Brightness and Auto-Lock Time

Your screen is one of the biggest battery consumers. Lowering brightness and shortening auto-lock time helps.

Steps:

1. Open Settings > Display & Brightness.

2. Adjust Brightness to a lower, comfortable level.

3. Go to Settings > Display & Brightness > Auto-Lock and choose 30 Seconds or 1 Minute.

This is especially useful if your iPhone is overheating after update.

6. Enable Low Power Mode

Low Power Mode reduces background activity, mail fetch, and visual effects to extend battery life.

Steps:

1. Go to Settings > Battery.

2. Toggle Low Power Mode on.

You’ll see slower animations and temporary restrictions on apps, but your battery will last longer.

7. Reset All Settings

Sometimes incorrect settings cause battery drain. Resetting settings does not delete your data but restores default system settings.

Steps:

1. Go to Settings > General > Transfer or Reset iPhone > Reset.

2. Tap Reset All Settings.

This can fix hidden issues affecting iOS battery life without harming your photos or apps.

8. Check for iOS Updates

Apple often releases patches to fix battery-related issues. Running the latest version ensures your phone has these fixes.

1. Go to Settings > General > Software Update.

2. If an update is available, tap Download and Install.

Keeping iOS updated prevents recurring iPhone battery draining fast iOS update problems.

9. Turn Off Location Services for Non-Essential Apps

Location services can drain your battery quickly, especially if multiple apps are tracking your location.

Steps:

1. Go to Settings > Privacy > Location Services.

2. Review apps using location and set them to Never or While Using.

This reduces background activity that contributes to iPhone battery issues.

10. Perform a Factory Reset (Last Resort)

If all else fails, a factory reset can restore optimal battery performance by eliminating software conflicts. Backup your iPhone first.

Steps:

1. Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.

3. Restore your backup afterward.

This can solve persistent battery drain problems caused by a corrupted update or glitch.
