I came to say this, the battery life in this beta version is dramatic, at least in my series 7. Tonight, in 7 hours it has spent 26%. Also if I put it to charge, it seems to me that it charges faster than it should. I think that's why it didn't come out at the same time as the rest of the betas, maybe there are problems in the charging system, because for example, I don't have apps on the watch that can drain the battery. also, yesterday I turned it off with 100% and connected to the charger off and when it started, it had 91%, something is wrong.I realize it's pretty quick turnaround regarding an opinion on this latest beta, but besides what initially scared the heck out of me being fixed, I'm seeing a bunch of improvements. Generally speaking, battery life is poor to abysmal during the Watch betas, and I've been getting excellent battery life. Charged up to 100% yesterday around 4pm, wore it to bed and woke up with 57% battery this morning. I set it on the charger just now to top it off and roughly 10-15 min later I'm back to 100%. I've also had issues with my S7 Watch not remembering my wireless SSID here at home, and if it does, it keeps that 'Private' setting enabled which then triggers my Xfinity app to let me know a 'NEW' devices has connected.. I wish they'd just give us an option to turn that off all together. But, anyway, it's remembering my SSID and that I had Private turned off..
It seems to me a serious error, I would not be surprised if they launch something this week to mitigate it. I have already sent the feed, to see if they solve it quickly, because two weeks with the clock like this, it will be the death of the battery, I will do more cycles than in the previous 6 months. I have also restored it twice, I don't know if continuing to restore the clock will help me in any way.
