Apple says closing apps won't improve battery life
Apple's senior vice president of Software Engineering, Craig Federighi, says that closing apps to save battery life won't have the desired effect.
When our battery life starts dipping, one of the first steps many smartphone users take is to close unused apps that are running. But Apple says that this won't help battery life at all.
In fact, it may actually have the opposite effect. Senior vice president of Software Engineering at Apple, Craig Federighi, explained that when you close an app, the OS has a process to go through to remove it from memory, which requires a certain amount of resource utilisation.
He explained that operating systems such as iOS are advanced enough that they can simply put apps into a sleep state of sorts when they're not needed and then wake them up. Apple says, "Apps that are in a suspended state aren't actively in use, open or taking up system resources."
Well that's a few seconds that we can save each day by not shutting down apps to save battery life.
