Is the iPhone cleaning process useless? Sometimes it really saves electricity

In the middle of last year, the news that Apple officially confirmed that cleaning the iPhone background was useless spread all over the digital corners. However, the fact is not as confident as Apple's reply. Sometimes the cleaning process can really save power.

Once upon a time, I would double click the Home button of the iPhone every night before going to bed to clean up every application process in the multitasking interface. However, since Craig Federighi, who is responsible for software development at Apple, confidently said that such behavior would not save power last year, he has stopped doing so himself. At that time, Apple even said: "Many people think that applications will run in the background and consume power, so cleaning them is the best choice, but in fact, the action of clearing applications may consume more power. Modern smart phones have enough cache, so after the deployment of applications by hand, they will automatically pause in the background, and they will not consume power at all. On the contrary, frequent shutdown and restart of applications will drag down your battery. "

However, in the subsequent long-term use without cleaning process operation, the author suddenly found that his iPhone occasionally turned off automatically when he woke up, just like the Android phone. After checking the battery consumption, he found that some applications still worked hard at high load in the late night until the iPhone turned off automatically.

If you use Apple's "disdainful" cleaning process method to terminate all running applications before going to bed, you will not wake up with no power on your phone.

So, which apps will seriously affect the energy consumption of the iPhone? The author found that the "culprit" is a large number of data backup applications (such as XX cloud disk, XX steward). Once the user has enabled data synchronization by default, a large number of photo data will be automatically backed up, and this part of the work can always be done in the background.

In fact, the backup of large amounts of data must be a high energy consuming task in Apple's eyes, because Apple's official backup task can only be performed when users are connected to the power supply and Wi Fi network. Third party applications with similar functions above do not require power connection at all.

The author also learned from the developers that for iOS system, there has always been a way to make applications run in the background for a long time. Although there are restrictions on such application behavior in iOS11, there are still ways to achieve it. Therefore, if you don't want to encounter the embarrassment of power failure, occasionally cleaning up the process is actually effective.
