Last week, my friend Sarah showed me her phone screenâshe was furiously swiping up to close every app after using it, her thumb moving like a metronome. âItâs the only way to keep my battery from dying by noon,â she said, squinting at her 32% charge. Iâve heard this habit from almost everyone I know, but is it actually doing any good?
The Truth About Closing Apps
Modern smartphones (iOS and Android) are designed to manage apps in the background efficiently. When you switch away from an app, it doesnât keep running full-tiltâit goes into a low-power âsleepâ state. Closing it completely means the next time you open it, your phone has to reload all its data from scratch, which uses more battery than just letting it stay in sleep mode.
Letâs compare the two actions side by side:
| Action | Battery Impact | Time Spent | Performance Effect |
|---|---|---|---|
| Closing apps manually | Higher (reloading uses energy) | A lot (swiping through apps) | Reload lag when reopening |
| Letting OS manage apps | Lower (sleep mode uses minimal power) | None | Smooth, instant access |
2 Key Myths Debunked
Myth 1: Closing apps extends battery life
This is the biggest myth of all. For most apps, staying in background sleep uses almost no battery. Closing and reopening them forces your phone to do extra workâloading images, data, and settingsâ which drains more power than leaving them alone. Sarah tested this: she stopped closing apps for a day, and her battery lasted an extra 90 minutes. She was shocked.
Myth 2: Background app refresh drains battery heavily
Background app refresh (the feature that updates apps while youâre not using them) gets a bad rap, but itâs not a major battery hog. Most apps only refresh a few times an hour, using tiny amounts of power. The exceptions are apps like navigation or live sports trackersâthose do use more, but you can turn off refresh for individual apps if needed.
âEfficiency is doing things right; effectiveness is doing the right things.â â Peter Drucker
This quote hits home here: closing apps is efficient at making you feel productive, but itâs not effective at saving battery. The right thing to do is let your phone manage apps on its own.
Q&A: What Actually Saves Battery?
Q: If closing apps doesnât help, what can I do to make my battery last longer?
A: Focus on the big battery drains:
- Lower your screen brightness (itâs the top battery user for most phones).
- Turn off location services for apps you donât use (like weather apps that donât need real-time location).
- Use dark mode (OLED screens use less power for black pixels).
- Update your OSâmanufacturers often fix battery bugs in updates.
Next time you find yourself swiping to close apps, remember: your phone knows what itâs doing. Save your thumb the effort and let it handle the background work.
