There is a myth about multitasking in iOS, which has always been discussed among the owners of iPhone and iPad. Supposedly the app in the iOS multitasking bar all the time active and slow down, clog the memory and reduces battery life of the device. “Experts” advise to improve performance and increase battery life devices to manually delete these apps. Today the main developer of iOS, Craig Federighi, refuted such claims.
9to5Mac reader named Caleb interested in this aspect of iOS and he decided to go with him directly to Apple. And the question he directed to someone, and the head of the company Tim cook.
“Hi, Tim
How often do you close apps in the multitasking pane of iOS and do I need to do to save battery? Just want you to stop this argument!”.
Apple executives don’t often carry on a correspondence with ordinary users of Apple gadgets. Nevertheless, it happens and such responses can be considered as the official position of the company. On a reader’s question said senior Vice President of Apple’s software, Craig Federighi.
“Hello, Caleb.
I know you asked Tim, but I can put in my two cents.
No and no again,” said Federighi.
I must say that the multitasking bar iPhone and iPad contains the list of active applications, and a list of recently run programs. The OS intelligently manages tasks independently or unloading “putting a pause” the active processes.
When the user presses the Home button the active program switches to background mode. Most of the tasks using a few seconds then move to suspended state. The first technical caveat is that suspended app remains in the device memory. This is done to ensure that it can continue to work faster if the user decides to go back to him. It does not use CPU resources and battery.
It can be assumed that if the program is in memory, then it should be removed therefrom to release the resources. In fact, iOS is doing it yourself. If Windows has suspended the app and the user runs a resource-intensive SOFTWARE, such as complex three-dimensional game, iOS itself unloads from memory the program is suspended and moves it to the disabled state. In other words it will be completely erased from the RAM and started from scratch upon next launch.
