Last week, my friend Sarah was panicking because her phone battery hit 15% halfway through the day. She furiously swiped up to close every app in her recent list, muttering about background apps draining power. I had to stop herāwhat she was doing wasnāt helping. In fact, it might have made things worse.
The truth about closing apps and battery life
Modern smartphones (iOS and Android) are designed to manage background apps efficiently. When you switch apps, the OS puts the old one into a low-power sleep mode. Closing it manually forces the app to restart from scratch later, which uses more battery than letting it sleep. Think of it like turning off your TV every time you leave the room vs. putting it on standbyārestarting takes more energy.
Closing vs. not closing: A quick comparison
Hereās how different actions affect your battery:
| Action | Battery Impact | Time Spent |
|---|---|---|
| Closing all background apps | Minimal to negative (restarting uses more power) | 1-2 minutes (swiping through lists) |
| Letting apps sleep in background | Low (OS optimizes power use) | 0 minutes (automatic) |
| Closing a frozen/misbehaving app | Positive (stops abnormal drain) | 10-15 seconds (single app) |
Debunking 2 common battery myths
Myth 1: Closing apps extends battery life
As we explained, restarting apps uses more energy than letting them sleep. A 2016 study by Google found that closing apps on Android had no significant impact on battery lifeāsometimes it even reduced it. The OS is smarter than you think at managing power.
Myth 2: All background apps drain battery
Most apps in the background donāt use much power. They might check for updates once in a while, but thatās negligible. The real culprits are apps that run constant processes: navigation (GPS), streaming (music/video), or apps that use your camera/microphone in the background. You can check which apps are draining your battery in your phoneās settings.
āEfficiency is doing things right; effectiveness is doing the right things.ā ā Peter Drucker
Druckerās quote hits home here. Closing apps is efficient at making you feel like youāre saving battery, but itās not effective. Instead, focus on actions that actually move the needleālike lowering screen brightness or turning off location services when you donāt need them.
Q&A: When should I close apps?
Q: Is there any time I should close apps manually?
A: Yes! If an app is frozen, crashing, or using an unusual amount of battery (check your battery usage stats). Closing it will stop the abnormal drain and let you restart it fresh.
Practical battery-saving tips that actually work
- Lower your screen brightness (itās the biggest battery drain for most phones).
- Turn off location services for apps that donāt need it (like social media).
- Use battery saver mode when your battery is below 20%.
- Update your appsādevelopers often fix battery-draining bugs.
Next time youāre tempted to close all your apps, remember: your phone knows what itās doing. Save your time and let the OS handle background apps. Your battery (and your sanity) will thank you.
