  • •Step 4: You can verify it is active by checking for the yellow battery icon in the status bar.
  • •Step 5: If it doesn't work, ensure your iOS is updated by going to Settings > General > Software Update.

For iOS 15 and later

In iOS 15 and later, Low Power Mode can also be accessed from the Control Center.
  • •Swipe down from the top-right corner of the screen to open Control Center.
  • •Tap the battery icon to enable Low Power Mode.

For iOS 14

In iOS 14, Low Power Mode is only accessible through the Settings app.
  • •Follow the steps mentioned above to enable Low Power Mode.

Method 2: Adjust Screen Brightness

Lowering your screen brightness can significantly reduce battery consumption. This method is useful in bright environments or when you want to conserve battery life.
  • •Step 1: Open the Settings app.
  • •Step 2: Tap on 'Display & Brightness'.
  • •Step 3: Adjust the brightness slider to a lower level.
  • •Step 4: To verify, observe the screen brightness change immediately.
  • •Step 5: If the brightness does not change, check for any accessibility settings that may override this adjustment.

Troubleshooting Common Issues

If you encounter issues while trying to extend your iPhone's battery life, consider the following solutions:
  • •Error: Battery not lasting as expected - Solution: Check for apps using excessive battery by going to Settings > Battery and reviewing the battery usage statistics.
  • •Issue: Low Power Mode not activating - Fix: Ensure your iOS is up to date and restart your device if necessary.

Advanced Tips & Shortcuts

For power users looking to maximize battery life, consider the following tips:
