Many owners of iPhone and iPad used to save the device battery, manually closing everything in the multitasking drawer app. Earlier, representatives of Apple, debunked the myth that this way you can prolong the battery life. The habit of close application to improve the autonomy of gadgets, as it turns out, may even be counterproductive.
According to its users, such actions help to increase the battery life without recharging, and to rid it of glitches and slowdown. However, the developer Hiroshi Lockheimer convinced that it is not only pointless, but in some cases leads to additional expenditure of charge.
Twitter user David Pearce asked Lockheimer whether closing apps in the multitasking drawer “just useless” or it may worsen the situation. To this he replied:
“It really can adversely affect battery life on one condition: you kill the task, and the system again decides to handle it”.
Most of the applications that are displayed in the panel multitasking iOS, either automatically “frozen” in the memory of the device, or completely unloaded, so they have no effect on the battery life. But if the user decided to re-apply to involuntary offloaded task, the re-opening of “from scratch” will cause additional CPU usage and faster battery drain. On Apple’s official website indicates that the closure application is necessary only in individual cases, when, for example, the program crashes or works incorrectly.
Earlier question about how it is appropriate to close apps in the multitasking drawer, asked Tim cook. And although Apple has not responded to the email user, he did a senior Apple’s Vice President of software Craig Federighi. “No and no again”, – said the chief developer of iOS and thanked the owner of the iPhone for the commitment of the company.
