GPS LocationListener and phone sleeping

I've created service which has LocationListener in it. In order to keep service running the service is set as foreground. I have some questions about phone power management and sleeping in that circumstances:

1. Will phone go to sleep while such service is running?
2. How can I save power in this stuati开发者_如何学Goon?

If you don't want the service to sleep then you can keep the device awake.

Snippet:

private PowerManager.WakeLock wakeLock; //member variable

somewhere in your service class:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "some_tag");

When you're done running then you can do:

wakeLock.release();

Yes.

How about a background Service that periodically gets launched using AlarmManager and goes back to sleep after persisting coordinates to a database or file?
