iPhone Battery Draining Fast? Settings To Check First

Guide 4b · Battery & Charging

Battery running down faster than it used to? Check your settings first. Often one app or setting is the cause.

Works on: Every iPhone on a recent iOS.

Step 1: See What's Using Battery

1. Open Settings and tap Battery.
2. Look at the list of apps. Tap an app to see how long it ran on screen and in the background.

One app uses a lot in the background? Update it, or delete and reinstall it.

Step 2: Limit Background App Refresh

1. Open Settings, tap General, then Background App Refresh.
2. Turn it off for apps that don't need to update in the background.

Step 3: Lower Brightness

Turn brightness down in Control Center, or let Auto-Brightness do it. It's in Settings > Accessibility > Display & Text Size.

Step 4: Turn On Low Power Mode

Open Settings > Battery and turn on Low Power Mode. It cuts back on background activity until you charge. You'll see the battery icon turn yellow.

Step 5: Update iOS

Open Settings > General > Software Update and install anything shown.

Step 6: Check Battery Health

If settings don't help, the battery itself may be worn. Our battery health guide shows you how to check.
