To put it simply, it is developer-friendly, but not device-friendly (it may secretly occupy traffic and power ).
For users, if you have enough bandwidth and are not sensitive to fever, you will enjoy a better application experience.

Since iOS 4, the app can continue running for a short period of time (10 minutes) after it is returned to the background ).

IOS 5 started with another type: download newspapers and magazines.
Then iOS 7 can download various things and capture them regularly.

Here are three new things:

Note the following:When an application is awakened by the above three types of wake-up, it is only given several seconds to process updates.

To sum up, I predict that the standby time of the next-generation iPhone will decrease and the actual available time will decrease, but the official nominal usage time will not change.
