My friend Lisa swipes up on her phone every 30 minutes like it’s a ritual. She closes every app in the background, convinced it’s the secret to keeping her battery alive until dinner. But by 5 PM, her screen still dims, and she’s scrambling for a charger. Is she wasting her time?
The big myth: Closing apps saves battery
Let’s get straight to it: For most modern phones (iOS or Android), closing background apps does not save battery. Operating systems are designed to suspend inactive apps—meaning they stop using power once you switch away. Closing an app forces it to restart from scratch next time you open it, which actually uses more battery than leaving it in the background.
To make this clear, here’s a quick comparison:
| Action | Battery Impact | Performance Impact | Time Spent |
|---|---|---|---|
| Closing background apps | Minimal to negative (restarting uses power) | Slower app reopening | 1-5 mins daily (cumulative) |
| Leaving apps in background | Low (OS suspends inactive apps) | Faster app switching | Zero |
2 more myths to stop believing
Myth 1: Charging overnight damages your battery
Remember when we were told to unplug phones before bed? Those days are gone. Modern lithium-ion batteries have built-in circuits that stop charging once they hit 100%. Leaving your phone plugged in overnight won’t overcharge it or shorten its lifespan.
Myth 2: Using your phone while charging is dangerous
Unless you’re using a faulty charger or cable, this is false. Phones are designed to handle charging and usage at the same time. The only risk? Your phone might get a little warmer, but that’s normal.
“Efficiency is doing better what is already being done.” — Peter Drucker
Drucker’s words ring true here. Closing apps is an inefficient task that doesn’t help your battery. Instead of wasting time swiping, focus on actions that actually make a difference.
Q: So what does save battery life?
A: Here are three proven ways:
- Lower your screen brightness (it’s the biggest battery drain).
- Turn off location services for apps you don’t need (like games).
- Use dark mode (OLED screens use less power for black pixels).
Next time you catch yourself swiping up to close apps, take a breath. Your phone knows what it’s doing. And if Lisa reads this? She’ll probably save 10 minutes a day—time better spent on things that matter.
