I’m still getting used to leaving apps open in the background. I know iOS is very good at freezing things in the background, but are there any situations where you should force close an app instead of leaving it sleeping in the background? My wife is constantly shutting everything on her X, while I’ve been leaving all of my apps running. Battery life seems good, I’m just curious more than anything. On Android if you open your phone and then power the screen off, the phone doesn’t sleep(doze) right away. Will an iPhone immediately go to “sleep” as soon as you power off the screen, or does the processor work in the background for a short time like on Android? Android has an app called “force doze” that you can use to force your phone to sleep immediately after shutting the screen off.
