    Since installing watchOS 3.1 yesterday, I'm seeing significantly improved battery life on my Series 2. It's been off the charger for almost 14 hours and it's only down to 79%. Normally, at this point in the day, it would be anywhere between 50 to 55%. Needless to say, I'm very satisfied with 3.1 thus far. Anyone else seeing similar results?

    Yep! My S2 SS off charger for about 13 hours and at exactly 79%. :)

    Yes - this is a dramatic improvement to the Watch. MacRumors should have one of their editors provide an updated battery stress test. It's an opportunity for them to scoop the rest of the tech media, nearly all of whom reviewed S2 with 3.0 and concluded that battery life was unfortunately similar to S0 (there were a few notable exceptions, such as a recent update from 9to5mac that I linked below).

    My own usage reflects an increase from around 24 hours battery life on 3.0 to well over 30 hours now, depending on watch face/complications, length and type of workout, music playback, etc. It's such a dramatic improvement with 3.1 that I would expect Apple to eventually change the language on its battery page, which currently describes having reached their 18 hour rating based on "pre release" software.

    This is good to hear. Through the forums, a lot of members have mentioned how their Series 2 has struggled with battery life. Sounds like 3.1 has addressed some of these issues.

    My launch-day 2015 Series 0 Apple Watch is at 72% right now, after mild use. Been off the charger since 9am, and it's 9:45pm. I've not noticed any battery life difference from 3.0.

    S2 42mm here and after 3.1 update battery life has improved a lot. I did have a decent battery life also with 3.0, but the difference is huge. I haven't made any other changes.

    After 3 hours my series 1 is 98%, huge battery life.
    In the past that happened a couple of times when I rebooted the Watch, then battery life went back to normal so I'll have to wait a couple of day to see if there is a real improvement.

    Yes, I've noticed also! After about 15 hours off the charger, I was only at 74%. Apps also load faster then previous OS.

    I'm at 27 hours off charge right now, had a 5K run early yesterday then a 5K walk last night plus all the regular stuff and I'm at 57%. But to be honest I was getting great battery life on 3.0 so it's hard to tell if it's better or not.

    With my 42mm AW2 and 3.1 I'm at 66% of battery after about 25 hours, (I admit, very light usage today) but yes it has improved a lot for me.
    Not that 3.0 was poor, I could do always 1 day with it but this is better.

    I'm curious if there is any difference in battery between 38 and 42 mm. I read that the 42 has bigger battery but I could not find any review / comparison between them

    I can confirm that my 42mm S1 has very significantly improved battery life with watchOS 3.1. After waking up with a full charge and now over 8 hours into the day (30 minute workout included), my watch is still at 90%. I would estimate that while running watchOS 3.0 with a very similar day, I would be at 60% or a little less typically. Also, two nights ago I wore it while sleeping and the battery only dropped less than 10% during 7 hours of sleep. I think I will try going for 2 days and 1 night in between on 1 charge now to see if it can survive and record my heart rate while I sleep every other night.

    VERY happy at the unexpected battery life gains with watchOS 3.1 !!!

    Anyone think Apple improved battery life in 3.1 to roll out Sleep tracking activity soon?

    I wouldn't be surprised if there is an internal debate over priority of the following features: Sleep Tracking, Cellular, and Always On Display. From these forums I've noticed that some users find one of the above features to be a game changer while others consider the same feature to be completely non-essential. Hopefully Apple will add all three of these features as soon as possible. :)

    Let's see how battery life is after a couple of days usage. As I recall, a number of folks have noted in the past that a reboot tends to provide a temporary(?) improvement.

    -Jeff

    p.s. my day one data point is that after 9-1/2 hours, there is 85% battery left.

    That's a possibility.
    Last night since Watch was 60% I wore it to track sleep and this morning I woke up with 40%, a quick charge and I'm ready for a full day of usage (starting from 70%).
    I have to say that I felt uncomfortable wearing the Watch in bed, so sleep tracking is not something I'm going to do with the Watch in the future.

    Well, I ended yesterday with 70% and kept wearing thru the night and woke up with 60%. The potentially BIG catch is that after my workout yesterday morning, the watch stopped automatically taking regular heart rate readings. So I went all day without a single heart rate test, which usually run every 8 minutes or less.

    Is anybody noticing this potential bug with watchOS 3.1?

    I was kind of thinking that as well.
    If the longer battery life is confirmed and they have decent sleep tracking, it could actually make me want the watch.

    Top tip for sleep trackers. Turn on airplane mode when you go to bed.

    I just started sleeping with my Apple Watch (sorry, had to go there:D). I have airplane mode on and raise to wake turned off. Only used 10% of my battery life overnight!

    Off charger since 730am. It's almost 9 now and I had an hour work out at the gym that I tracked, it's at 70%. Usually, I take people claiming better battery life with a grain of salt as it's usually just from the repairing of the watch to the phone. I think this is the real deal though.
