Apple: Turning off apps running in the background on iPhone is useless, it only wastes battery life

Turning off applications running in the background on iPhone will help free up memory, processing power, save battery and make the device run "smoother". This is a misconception that many people have.

According to Apple's information about closing apps running in the background, it clearly states that "you should only close the app if it is unresponsive." The reason is that Apple has long designed iOS to ensure that background applications hardly use the iPhone's RAM or CPU.

Technically, frequently closing apps in the multitasking window can have a worse impact than just letting them run in the background on the iPhone. That's because these applications, when running in the background, will "freeze", not really affecting the battery or performance of the device. The image that users see when swiping up from the bottom of the home screen is just a visual indicator that they have recently opened and are ready to resume when needed.

In fact, the first launch of most applications requires a short burst of performance to load and collect their data, so closing applications and then having to reopen them later often consumes more battery. is to just leave them in the background. This is similar to turning the air conditioner on/off continuously will consume more electricity than just leaving it running.

An application frozen on the multitasking screen will consume less power, except for applications that play music or use GPS. As for social networking applications, they still have to run to push notifications to you, so turning them off is meaningless.
