Responding to many users complaining that iPhone battery life is getting shorter and shorter, Apple officials responded that sliding off applications may shorten iPhone battery life.
According to Apple’s official statement, sliding up and closing the iPhone application may make the App take longer to reload, and users can slide up and close the application when the application becomes unresponsive.
Apple said: “When the application that the user is using appears, the previously opened application will be frozen and in standby mode to help users perform multi-tasking without taking up additional resources on the device.”
In fact, as early as 2016, foreign media sent an e-mail inquiry to Cook about this issue. Although there was no direct response, Craig Federighi, then the senior vice president of Apple Software, gave a negative answer, saying frequent killings The background will not help the device’s battery life.
In Apple’s official technical support document, they have stated that “killing the background”, that is, forcibly closing the app, is only recommended to operate when the app is not responding. “When apps you ’ve used recently appear (multitasking pages), they ’re not open, they ’re in standby mode to assist you with browsing and multitasking. You should only force an app when it ’s not responding Close it, “Apple wrote in the technical support documentation.
With regard to the above problems, some professionals have stated that the applications in the background of the iPhone are actually frozen. This can limit the operations they can perform in the background and release the RAM being used.
Professionals point out that forcibly exiting an app is not only useless, it actually makes the experience worse. If the user forcibly quits the application in the background, it will have a negative impact on battery life, and it will take longer to switch applications
If users are concerned about applications running in the background of the iPhone, Apple recommends that users check the background running permissions of these applications in the “iPhone Settings”.
It is worth mentioning that Apple finally stated that if the background is frequently killed, it will lead to a new round of “hot startup” when the application is re-opened. In addition to extending the startup time, it will also occupy additional memory , Which increases battery drain and makes the device slower.
