Apps Draining iPhone Battery: How to Stop It

Guide 10-38254 · Updated · Step by step

If your iPhone battery is dying faster than it should, a few energy-hungry apps are likely the cause. You can stop the drain by checking Battery usage in Settings, turning off Background App Refresh for the worst offenders, and adjusting location and notification settings. This guide explains how to find the culprits and fix them for good.

Why Some Apps Drain Your Battery

Every app uses power, but some use far more than others. The main culprits are apps that keep running in the background, constantly refresh data, or use power-hungry features like GPS, high screen brightness, or heavy graphics. Social media apps, navigation apps, and games are common offenders because they rely on network connections and sensors. Even apps you don’t open often can drain battery if they refresh in the background or send frequent location updates.

How to Find Which Apps Use the Most Battery

Your iPhone tracks battery usage by app. Go to Settings > Battery and tap the last 24 hours or last 10 days. You’ll see a list of apps with their usage percentage. The list shows both “On Screen” and “Background” activity. Apps with high background activity are the ones draining your battery when you’re not using them. Tap an app to see more details, like how long it was active and whether it used location services.

Quick Fixes to Stop Battery Drain

Once you’ve identified the problem apps, try these steps in order:

  • Turn off Background App Refresh for that app: Go to Settings > General > Background App Refresh and toggle off the app. This stops it from updating content in the background.
  • Check Location Services: Go to Settings > Privacy & Security > Location Services. For each app, set to “While Using” instead of “Always.” Apps like weather and maps only need location when open.
  • Reduce Notifications: Go to Settings > Notifications, select the app, and turn off notifications if they’re not essential. Each notification wakes your screen and can trigger background activity.
  • Close the app from the App Switcher if you’re not using it. Swipe up from the bottom and swipe away the app card. This forces it to stop running.
  • Update the app: Check the App Store for updates. Developers often fix bugs that cause battery drain.

When to Delete the App

If an app still drains your battery after trying the fixes, consider deleting it. Some apps are simply poorly optimized. If you need the app, try reinstalling it—this can clear corrupted data. For apps you rarely use, deleting them is the best way to stop the drain. You can always reinstall later.

Other Battery-Saving Settings That Help

Beyond individual app settings, these system-wide changes reduce battery drain:

  • Low Power Mode: Turn it on from Settings > Battery or Control Center. It reduces background activity and performance.
  • Reduce Screen Brightness: Lower the brightness or turn on Auto-Brightness in Settings > Accessibility > Display & Text Size.
  • Turn off Push Mail: If you use email, set it to fetch manually instead of push.
  • Disable unnecessary widgets: Widgets update in the background. Remove ones you don’t use.

Common Myths About Battery Drain

Many people think that closing all apps from the App Switcher saves battery. In reality, reopening an app uses more power than leaving it paused in the background. Also, using Wi-Fi instead of cellular data generally saves battery, but a weak Wi-Fi signal can drain more because the phone boosts its antenna. Finally, charging overnight is safe—modern iPhones stop charging at 100% and trickle charge as needed.

Frequently Asked Questions

How do I know if an app is draining my battery?

Check Settings > Battery. The list shows which apps use the most power. If an app has high background activity, it’s likely draining your battery.

Should I turn off Background App Refresh for all apps?

No, that would break features like email syncing and weather updates. Turn it off only for apps that you don’t need to update in the background.

Does dark mode save battery?

On iPhones with OLED screens (iPhone X and later), dark mode can save a little battery because black pixels are turned off. On older LCD screens, there’s no difference.

Why does my battery drain fast even with low usage?

It could be due to poor cellular signal, old battery health, or an app that’s stuck in a loop. Check Battery Health in Settings > Battery > Battery Health. If it’s below 80%, consider replacing the battery.

Can a VPN app drain battery?

Yes, VPNs encrypt and route all your traffic, which uses extra power. If you don’t need it, turn it off.

Is it okay to use battery-saving apps?

Most battery-saving apps don’t actually help—they just close apps or change settings you can adjust yourself. They can also run in the background and use more power. It’s better to use the built-in settings.
