You need to assert a wake lock to prevent the cpu from going to sleep using PhoneWakeState.

But according of Erel quote "Once your process is killed the wake lock is released. You can call Service.StartForeground to prevent it from being killed."
We haven't to use it

A foreground service will prevent the OS from killing your app.
A wake lock will (try to) prevent the device from going to sleep.

@Erel : IMHO, a collection of a few statements like those will be able to reduce forum's recurring questions. I mean, a short list of "updated best practices" were only short sentences like "do it this way" will find place. That will suffice to a great part of developers. Then each sentence could refer to a more thorough explanation.
ps: I know that often it doesn't exist a single optimal way to solve a problem but here I am referring to sentences like "prefer maps to lists, never use ExitApplication etc", anything useful to avoid errors or problems to inexperienced new users (and experts alike..eheeh).

(and experts alike..eheeh)

In fact, I use ExitApplication. (Well, I am "Expert" just according to the text under my avatar )

... and now I'm going to look for what IMHO means
