10 Tips to Fix Fast Battery Drain Issue on iPhone 15/15 Pro

Is your iPhone 15 series draining its battery faster than you’d like? If so, you’re not alone. While the new¬† devices offer incredible features, heavy usage and certain settings can lead to battery drain issues. In this guide, we’ll explore some practical solutions to help you optimize your iPhone 15, iPhone 15 Plus, iPhone 15 Pro, or iPhone 15 Pro Max’s battery life, ensuring you can enjoy your device throughout the day without constantly searching for an outlet.

How to Fix Fast Battery Drain Issues on iPhone 15 Series

1. Check Battery Usage

Begin by identifying which apps are consuming the most battery power. Go to Settings > Battery, and you’ll see a list of apps and their battery usage. If you notice a particular app draining the battery excessively, consider using it less or adjusting its settings.

2. Update iOS

Ensure your iPhone is running the latest iOS version. Apple frequently releases updates that include battery optimization improvements and bug fixes. Go to Settings > General > Software Update to check for and install updates.

3. Manage Background App Refresh

Background App Refresh can significantly impact battery life. Navigate to Settings > General > Background App Refresh and disable it for apps that don’t require constant updates. This prevents apps from consuming power when not in use.

4. Reduce Screen Brightness

High screen brightness can be a major battery drain. Lower your screen brightness by swiping down from the top-right corner to access Control Center. Adjust it to a comfortable level to conserve battery.

5. Enable Low Power Mode

When your battery is running low, enable Low Power Mode through Settings > Battery. This mode reduces performance and minimizes background processes, extending battery life. Consider using it when you need your iPhone to last longer.

6. Manage Location Services

Apps that use location services can drain your battery. Review which apps have location access in Settings > Privacy > Location Services, and disable it for apps that don’t need it.

7. Check for Background Processes

Make sure no apps are running in the background by swiping up from the bottom on your device and swiping away unnecessary apps in the app switcher.

8. Reduce Unnecessary Push Notifications

Push notifications from apps can trigger background processes and drain your battery. Review your notification settings in Settings > Notifications and disable notifications for apps that you don’t need immediate alerts from. This can help reduce battery drain.

9. Manage Widgets and Widgets Suggestions

Widgets can provide useful information but can also use up battery life if overused. Remove unnecessary widgets by swiping right to your Today View, scrolling down, and selecting “Edit.” Remove widgets you don’t frequently use.

10. Reset Settings

If you’ve tried everything and still face battery drain issues, consider resetting all settings to their defaults. This won’t erase your data but can resolve any misconfigured settings causing the problem. Find this option in Settings > General > Transfer or Reset iPhone > Reset.


By implementing these tips, you can significantly improve your iPhone 15 series’ battery life. A combination of managing app usage, optimizing settings, and staying up to date with iOS updates will help ensure you enjoy longer-lasting battery life on your iPhone.
