Why doesn't Apple have to clean up the background?

Apple's official suggestion is that unless the application is unresponsive, it should be deleted in the background, otherwise there is no need to slide out, which is not only useless, but also very harmful to the battery. Prior to this, Apple's senior vice president of software engineering also replied to the user's email, saying that quitting the application would not save power for the device.

In other words, completely closing an application from the multitasking interface and then restarting it will take up more system resources and power consumption than waking up the application again.
