Disable Location Services

One of the biggest causes of battery drain in iOS is location services. Apps that constantly access your location in the background can significantly reduce battery life.

To check which apps are using your location, go to Settings > Privacy > Location Services. Review the list of apps and turn off location access for any apps that don’t need to know your location. Social media apps, shopping apps, and other non-essential services are common culprits.

You can also toggle location services off completely when you’re not using them. The Location Services menu has overall toggles for disabling location access while using the device and disabling it entirely. Both options will improve battery efficiency.

How to Turn Off Background App Refresh

Background App Refresh is an iOS feature that allows apps to refresh their content and data in the background when you’re not using them. It’s convenient, but also taxing on the battery.

Disabling Background App Refresh can have a significant impact on battery life. Go to Settings > General > Background App Refresh and toggle it off. You can also go into each individual app’s menu and disable Background App Refresh just for specific apps.

This will prevent apps from using up battery in the background when you’re not actively using the app. Check back in a day or two to see if it improves battery efficiency.

How to Reduce Screen Brightness

The iPhone’s display is one of the most power-hungry components. The brighter you set the screen, the more battery it uses.

Go to Settings > Display & Brightness and drag the brightness slider to the left to reduce the screen brightness. Lowering it even 20-30% can extend your battery life. Auto-Brightness can also help optimize the screen based on ambient light.

You can also set the Auto-Lock time to 1 or 2 minutes. A shorter timeout will turn the screen off sooner when you’re not using the phone. Go to Settings > Display & Brightness > Auto-Lock to adjust this.

Finally, try using Dark Mode. The darker color palette requires less power to display on OLED iPhone screens. Go to Settings > Display & Brightness > Dark to enable it.

How to Force Close All Apps

Apps that run uncontrolled in the background can gradually drain your battery. Force closing apps you aren’t using can help optimize battery efficiency.

To force close apps on iPhone X or later, swipe up from the bottom of the screen and pause in the middle. Swipe right or left to scroll through open apps, then swipe up on any apps you want to close. This ensures apps aren’t continuing to run in the background when not needed.

You can also double click the Home button on older iPhones to show open apps, then swipe up on each app to close it. Make sure to re-open apps as you need them to avoid losing any unsaved progress.

How to Update to the Latest iOS Version

Apple will often release subsequent iOS updates with bug fixes and performance improvements shortly after a major release like iOS 17.3.1.

Go to Settings > General > Software Update to check for any new iOS updates. Installing the latest available version could resolve excessive battery drain issues introduced in the previous update.

Be sure to read the release notes for any new updates to understand what’s changed. Updates with fixes specifically targeted at battery life, performance, or optimizations will be your best bet.

How to Reset All Settings

If you’ve tried other troubleshooting steps without success, resetting all settings on your iPhone may help resolve software-related battery drain issues.

Go to Settings > General > Reset > Reset All Settings. This will restore default settings on the iPhone without deleting your data. Make sure to reconfigure any customized settings you had previously changed after resetting.

Resetting settings can eliminate any problematic settings that may be causing battery life problems, without needing to fully erase the device. Check if battery life improves over the next 1-2 days.

How to Erase and Restore iPhone

The nuclear option to fix battery problems is to completely erase and restore your iPhone software using a computer. This will install a fresh copy of the latest iOS version, removing any bugs that may be causing battery drain issues.

Before erasing, make sure to backup your iPhone either locally or to iCloud. Then connect the iPhone to a computer and initiate a restore in iTunes or Finder. The iPhone will be wiped and iOS will be reinstalled from scratch.

When the restore is complete, you can choose to restore from your backup, or set up the iPhone as new if you suspect your backup file may contain software glitches affecting the battery. Monitor battery performance over the next few charge cycles.

Contact Apple Support

If you still experience rapid battery drain after trying all other troubleshooting steps, the issue may require further investigation by Apple. Contact Apple support via phone, online chat, or book a Genius Bar appointment at an Apple Store.

Provide them with details on when the battery drain started, steps attempted already, and any other observations that could aid in diagnosing the problem. They may suggest further software troubleshooting steps, or determine that the iPhone requires servicing if there is a hardware issue.

Getting help directly from Apple Support can pinpoint stubborn battery drain problems that standard user tips are unable to resolve. They can check diagnostic logs from your iPhone and match your usage patterns against expected battery performance.
