Last week, my friend spent 5 minutes furiously swiping up to close every app on her iPhone before heading to a concert. She swore this ritual would keep her battery alive long enough to capture the encore. But does closing apps actually save battery? Letās dive in.
The Big Myth: Does Closing Apps Save Battery?
Modern smartphones (iOS and Android) use sophisticated operating systems that manage background apps efficiently. When you switch to another app, the OS suspends the inactive oneāmeaning it stops using most power. Closing an app completely forces it to reload from scratch next time you open it, which uses more battery than just leaving it suspended. So that 5-minute swipe fest? Itās actually counterproductive.
Closing Apps vs. Leaving Them: A Quick Comparison
Letās break down the differences between these two common actions:
| Action | Battery Impact | Convenience |
|---|---|---|
| Closing all background apps | Higher (reloading uses extra power) | Lower (you have to reopen apps from scratch) |
| Leaving apps in background | Lower (OS suspends non-active apps) | Higher (apps open instantly when needed) |
Two More Battery Myths to Stop Believing
Myth 1: Charging overnight damages your battery
Older nickel-cadmium batteries suffered from "memory effect," but modern lithium-ion batteries donāt. Your phone stops charging once it hits 100%, so leaving it plugged in overnight wonāt harm it. In fact, some manufacturers recommend keeping your battery between 20-80% for long-term health, but overnight charging isnāt a problem.
Myth 2: Turning off Wi-Fi is better than airplane mode
Airplane mode disables all wireless radios (Wi-Fi, cellular, Bluetooth) at once, which saves more battery than turning off just Wi-Fi. If youāre in an area with no signal, airplane mode prevents your phone from constantly searching for a networkāanother big battery drain.
A Classic Wisdom to Remember
"Fix what is broken, but donāt fix what isnāt." ā Unknown (common tech wisdom)
This applies perfectly here. Instead of wasting time closing apps (which isnāt broken), focus on fixing actual battery drains like high screen brightness or unused location services.
FAQ: What Actually Drains My Battery the Most?
Q: Iām always running out of battery by midday. What are the biggest culprits?
A: The top three are:
1. Screen brightness: Keep it on auto-brightness to adjust to light conditions.
2. Location services: Turn off for apps that donāt need it (like games or social media).
3. Background app refresh: Limit this to essential apps (like email or navigation).
Final Tips for Longer Battery Life
Instead of closing apps, try these practical steps:
- Use battery saver mode when your battery drops below 20%
- Turn off Bluetooth and NFC when not in use
- Update your OS regularly (manufacturers fix battery bugs in updates)
- Avoid extreme temperatures (hot or cold) which drain battery faster
Next time you reach for your phone to close apps, remember: your OS is smarter than you think. Save your time and your battery by focusing on the things that actually matter.
