This starts to be so confusing that I'll stick with 10.52 beta. It works fine and is having Galileo support and no battery drain.
Can you clarify what you mean by 'no battery drain'? Are you talking about the 3rd party watch faces killing that battery?
Also ... turned off auto-update.
Thanks
Yes. I don't know about 10.0 sw but in 9.2 there was the issue about 3rd party watchfaces draining the battery. Now when having 10.52 beta, battery goes down less than ~0.26%/hour with 3rd party watchface (also showing heartrate) which means more than 2 weeks usage without charging. Of course activities will shorten the time.
