Last week, my friend Sarah spent 10 minutes every hour closing all her smartphone appsâInstagram, WhatsApp, even the weather appâconvinced it was the only way to keep her battery alive till evening. She was shocked when I told her she might be doing more harm than good. Is closing apps really the battery saver we think it is?
The Truth About Closing Apps
Modern smartphones (iOS 14+ and Android 10+) are designed to manage apps efficiently. When you switch away from an app, the operating system (OS) suspends itâmeaning it stops using most power but stays in memory for quick access. Closing an app completely forces it to restart from scratch next time you open it, which uses more battery than letting it stay suspended.
For example, if you close your email app and reopen it an hour later, the app has to reload all your messages and reconnect to the server. Thatâs more energy-intensive than just waking it up from suspension.
3 Common Battery Myths Debunked
Letâs break down three persistent myths and their realities:
| Myth | Reality | Impact on Battery |
|---|---|---|
| Closing apps saves battery | Modern OS suspends inactive apps; restarting uses more power | Negative (wastes battery) |
| Background app refresh drains battery | It uses minimal power; disabling may break notifications | Minimal (keep on for essential apps) |
| High brightness is the only screen drain | Auto-brightness adapts to light; dark mode on OLED saves 30%+ power | Partial (brightness matters, but dark mode helps) |
A Word on Efficiency
âEfficiency is doing better what is already being done.â â Peter Drucker
Druckerâs quote perfectly applies here. Smartphone OS are built to optimize battery usage automatically. Our manual attempts to âfixâ things (like closing apps) often disrupt that efficiency. Think of it like turning off your fridge every time youâre not using itâyes, it saves power in the short term, but restarting it uses more energy than leaving it on.
Practical Battery-Saving Tips
Instead of closing apps, try these simple tricks:
- Lower your screen timeout (set it to 30 seconds instead of 2 minutes).
- Use dark mode on OLED screens (it turns off individual pixels, saving power).
- Turn off location services for apps you donât need (like games).
- Update your appsâdevelopers often fix battery-draining bugs.
FAQ: Should I Ever Close Apps?
Q: If closing apps doesnât save battery, when should I do it?
A: Only if an app is frozen, crashing, or using excessive power in the background. You can check which apps are draining battery in your phoneâs settings (look for âBattery Usageâ or similar). For normal, well-behaved apps, let the OS handle them.
Next time you reach for that app switcher to close everything, remember: your phone knows better than you think. Save your time (and battery) for things that matter.
