Anybody else have a bluetooth power drain issue? Everything about Mate 9 is great, but I do have this issue with the bluetooth draining my battery. I would turn on the bluetooth to use it with my earphone. After I'm done, I would turn off the earphone and turn off bluetooth, but then I notice that my battery would drain like crazy. Only thing that helps is if I restart the phone. Any suggestions or am I doom to do a factory reset?
