I'm pretty satisfied with mines, it's not as bad as every made it out to be. The battery doesn't drain as much as people complain about. I mostly have 50% by close of business when I get home at 5. So pretty much I don't run out of juice.
Happy with 50% + or - at the end of the day and that is with wrist raise on
Totally happy with my battery life. Though I panicked this morning (9AM) when I saw the battery at 90% (took it off the charger this morning at 6AM with 99%). So, I unpaired my watch and re-paired it and it dropped to 84%.
I think I'm just being paranoid...
how long was the gap before the drop? it takes me 50% for about 9 hrs, so that's roughly 5.5% per hour, or .09% per minute haha.
If by gap you mean the time spent unpairing and pairing, then about 11-16 minutes...give or take a few minutes.
EDIT: It has dropped 6% in the past hour and a half. Someone please tell me I'm just being paranoid...
