My phone kept draining every 2 hours and the back of the phone would get will hot. The top app that was using the battery was Exchange Services. I kept recharging my phone like crazy and its already time consuming. I even had to delete my 2 corporate accounts like its almost useless to have phone like this.
To make sure that everything was cleared out, I powered off and powered on my phone. Then I re-added the 2 accounts. That stopped the battery drain and the over heating. Also Exchange Services had dropped completely off the list of top apps using the battery.
I would like to know if you also have the same problem as mine. I don't know but I have this Point of Sale system application in my nexus. But the problem is I dont know how to remove it..
