Apple has sought to put an end to the online rumour mill which suggests that disabling apps which are not in use can enhance battery performance, by affirming that no such benefits accrue.
Bearer of the bad news is Apple’s iOS chief Craig Federighi who confirmed that force closing apps made no difference to the expiry time of the battery, following an email to Tim Cook by one curious Apple user who wrote ‘do you quit your iOS multitasking apps frequently and is this necessary of battery life?’
The short answer was ‘no and no’ but this should come as no surprise as Apple has long stressed that ‘generally, there’s no need to force an app to close unless it’s unresponsive’.
Contrary to popular belief multitasking apps which appear in the background are placed in a ‘suspended state’ after a ‘short period of time’ according to Apple, after which they cease to consume any system resources.
Good mobile housekeeping does extend to disabling location services on apps where the functionality is not necessary and cutting background refresh on apps which are not in use, both of which will help your battery go the extra mile.
