Since 11.4.1.27 update, I had battery drain, my tablet never gone to deep spleep.
I inspected with BBS the partials wakelocks and found severals apparented to wifi and google play servives.
First I have disabled services (with application DisableService), in "Services GooglePlay" (system part) :
- All GcmReceiverService
- GcmSchedulerWakeUpService
- All Wearable services
The partials wakelock were gone, but no deep sleep...
I rebooted the device and miracle deep sleep was come back !
I reenables all services, deep sleep always here, used play store, maps etc... Oops no deep sleep anymore.
Finally I only disable GcmSchedulerWakeUpService and until now it's resolved. I don't see unvailable functionality in relation with disabling GcmSchedulerWakeUpService.
Hope it will keep going and help people in the same situation.
