New reports state that closing the apps on our iPhones don’t save battery and can, in fact, drain your battery faster.
Technology specialist John Gruber has published a lengthy post about why force closing your opened applications actually uses more battery.
In the post, he wrote: “Not only does force quitting your apps not help, it actually hurts. Your battery life will be worse and it will take much longer to switch apps if you force quit apps in the background.”
The reason, John states, is that the smart people who make iPhones have designed the Apple iOS to be energy saving.
So, when you switch amongst apps without closing it, your phone will ‘freeze’ the closed app and while it is in this suspended position, it will use barely any power until you reopen it!
This is seconded by an official Apple report, which tells users when they should force close applications: “When you double-click the Home button, your recently used apps appear. The apps aren’t open, but they’re in standby mode to help you navigate and multitask. You should force an app to close only when it’s unresponsive.”
