Closing iPhone Apps Doesn’t Save Battery-Here’s Why

If you regularly swipe away apps from your iPhone’s multitasking screen to save battery, you might be wasting your time.

Many iPhone users believe that closing background apps improves performance and extends battery life. However, Apple’s iOS is designed to manage inactive apps automatically, and repeatedly force-closing them doesn’t necessarily save power.

In fact, constantly closing and reopening apps can sometimes use more energy than simply leaving them alone.

Here’s why you should stop swiping away every app—and what actually helps improve iPhone battery life.

10 Annoying iOS 27 Settings and How to Fix Them

1. Why Closing iPhone Apps Doesn’t Save Battery

When you switch away from an app, iOS typically allows it to run briefly before suspending it.

Suspended apps generally aren’t actively using your iPhone’s processor. Instead, iOS keeps their state available so you can return to them quickly.

Force-closing an app removes it from the app switcher, but that doesn’t mean you’ve stopped a battery-draining process.

When you reopen it, your iPhone may need to load the app and its data again.

Apple recommends closing an app primarily when it becomes unresponsive, not as a routine battery-saving technique.

2. Check Which Apps Actually Drain Your Battery

Instead of closing everything, identify which apps consume the most power.

1. Open Settings.

2. Tap Battery.

3. Review battery usage by app.

4. Check for unusual background activity.

If an app uses excessive battery, consider updating it, changing its permissions or limiting its background activity.

3. Turn On Low Power Mode

One of the easiest ways to extend battery life is to enable Low Power Mode.

Go to Settings → Battery and enable Low Power Mode. On some iPhone models and iOS versions, you’ll find it under Power Mode.

This reduces certain background activities, visual effects and automatic processes to conserve energy.

It’s particularly useful when you’re traveling or can’t charge your iPhone for several hours.

4. Limit Unnecessary Background App Refresh

Some apps can fetch new content while you’re not using them.

To manage this, open Settings → General → Background App Refresh.

You can turn the feature off for individual apps that don’t need frequent updates or disable it more broadly. Keep in mind that some apps may take longer to show fresh content afterward. 

5. Reduce Screen Brightness and Check Battery Health

Your display can be a significant source of battery consumption, especially at high brightness.

Lower brightness when comfortable and enable Auto-Brightness under Settings → Accessibility → Display & Text Size.

Also visit Settings → Battery → Battery Health (the exact menu varies by model) to check your battery’s condition. If maximum capacity has declined significantly, changing software settings may provide only limited improvement.

When Should You Actually Force-Close an App?

There are legitimate reasons to swipe an app away, such as when it freezes, stops responding or behaves incorrectly.

But there’s no need to clear your entire app switcher every day. Apple explicitly states that quitting unused apps doesn’t prolong battery life.

Final Verdict

Stop force-closing every iPhone app to save battery. iOS already manages suspended apps efficiently.

For better battery life, focus on the settings that actually matter: Low Power Mode, screen brightness, background activity and battery health.

These small changes are more useful than repeatedly swiping away apps.
