Since last week I am seeing substantial battery drain on my Xperia M2 and the power management 'app' says that it is almost all (82%) due to bluetooth.It does not say what is requesting the bluetooth. I cannot yet identify the cause, so cannot say that GC is causing it but GC Mobile Android looks like it got updated last week and is my heaviest user of BlueTooth (to my Fenix 3 and VSHR) - is anyone else suffering from serious battery drain since about the end of January?
