Does swiping up to force close apps on your smartphone save battery life?

No, it actually uses more battery to load them from scratch the next time.

  1. Yes, it stops them from running
  2. No, it uses more battery later ✔
  3. Yes, it clears the phone memory

Why: Smartphones freeze apps in the background so they use zero power. Force closing them means the phone has to work hard to reboot the app later.

Huh, didn't know that: You only need to force close an app if it is completely frozen and not responding.

The dad joke
Why did the app go to the doctor? It kept crashing.
