Hello! I had a 38mm Sport watch shortly after they came out, and I returned it because I was regularly running out of battery (on top of having a lot of notifications out of sync with my iPhone). I usually used the workout mode for 45 minutes–1.5 hours every day, and often times was in reserve in the evening. Is this any better with watchOS 2? Thanks!
 
I haven't noticed any better (or worse) battery life than I had on 1.0.1.
 
Mine is about the same...42mm with 45 min workout and with watch on from 730am-midnight I end with 40-45%
 
Mine didn't seem so bad at first. Then a couple days ago it ran down to about 1 percent in 12 hours. Today I first put it on at 10 a.m. it was down to 59 at 2 p.m. At 6 p.m. it was down to 10. So I'm a little concerned now, especially since I turned off Hey Siri when I saw the 59 percent.
 
Ok my battery life was brilliant on OS 1.01. I upgraded to OS 2 on Monday and noticed no difference from OS 1.01
Unpaired my 6 Plus and bought a 6s plus yesterday. Paired my watch to it yesterday afternoon and my battery life sunk like a lead balloon at 10% per hour. Reset the watch and put it on charge and I have been wearing it for three hours this morning and used it several times for Apple Pay and emails and it's still reading 100% which if that is a true reading is amazing
 
Once I upgraded from OS2 GM to the official OS2 the battery was crap (I have a 38MM). I realized "Hey Siri" was turned on so I disabled that (with the 38MM it just sucked too much battery and I never use it). That didn't really help with battery discharge so i followed the suggestion folks had made - I re-paired my watch and let it charge to 100% and since then the battery life has actually improved - on my 38 MM three days in I'm getting slightly better battery life than I did before....I usually put on the watch at 7 am and leave it on until around 1030 - 11 pm and I still have around 30% battery left. It just depends on how many notifications I get throughout the day.
 
First full time using it today.. Off charge at 8am and with a hour walk at 23.00 it still has 21% left...
 
Been using the watch since 1st May. Before this weekend, I'd never gone below 40% battery at the end of the day (I'm not a heavy user).

Installed OS2 last Tuesday and all was still fine through to Friday. However, at the weekend the battery usage went a bit haywire. I got to 40% after 5 hours on Saturday. Yesterday I went from 100% to power reserve mode in 11 hours (first time I'd actually seen reserve mode).

Did the good old switch off and on again last night. Today I'm at 86% after 5 hours so seems back to normal for me. Very strange.
 
Sometimes my battery is fine, in 12 hours it usually goes to 70%. This morning, however, it's being drained by something. In two hours its gone 12%, whereas it usually drains at 2-3% an hour with my usage. I don't get it, it seems so temperamental. It's fine at first and then just starts draining like crazy. I reset it and will see if that helps.
