I have a problem with GCM on iOS on IP 13 pro. Application even barley used drains 13-15% (1 min onscreen and two hours backgorund) battery per day with is massive - tops as 3rd app regullary.
What I've tried:
*Phone restart
*Disable location permission for GCM
*Reconnect watch
*Disabled background refresh
Anyone had similar problems maybe? it drives me crazy, really.
