Wow 30% battery drain when using sleep tracking seems very excessive, I charge my Series 3 right before bed and it only looses around 5% overnight. Granted I am not currently sleep tracking as of yet, but I'm sure others who currently use 3rd party apps to track sleep don't loose 30% overnight either, I'm pretty sure 10% is the ballpark figure I've seen people reporting. You'd have thought since its 1st party built directly into the OS it would be better optimised, lets hope its just an early beta issue and it get improved before public release.
Also does anybody know if this sleep tracking will be on the Series 3 or is it one of the newer watches only?
