Check battery level of beacons which not belongs to us Android

I can't find in documentation any "getBatteryLevel()" or smth like that , so I came here. Is there any way to check battery level of beacon which not belongs to us. For example, my friend have app which checks level of battery in beacons owned by me. App must work on android.

I would be grateful for any link with the method if it's possible.
