Over at The Verge Ashley Carman asks, Should you force close your apps?
No. No. No.
It drives me crazy when I see people do what Carman describes (and I see a lot of people do it):
I force close my apps all the time. I double click the home button on my iPhone 6S and close out of every app I’ve used, even in the past 20 minutes. It’s a terrible habit, but it makes me feel good.
I wrote about this over 4 years ago and what I wrote remains true: swiping up to kill background apps kills your battery life because it forces iOS to relaunch apps, versus merely ‘waking them up’ from their suspended background state.
What I discovered on my new iPhone X running iOS 11.2 is that Apple has made it a bit harder to close apps.
Now when you bring up the app switcher swiping up on an app card simply brings you back to your Home screen. In order to close apps, you have to bring up the app switcher and then long-press on any app card. This causes red close icons to appear in the corners of all the app cards. Now you can swipe up on app cards to close them.
But you don’t need to, so leave them the fuck alone.
