    Let me preface this with a disclaimer: I had updated my Apple Watch Sport to WatchOS 2 GM before it went public (and before that "breaking bug" was found by Apple).

    I had checked my Apple Watch for updates yesterday and noticed WatchOS 2 officially launched. I placed it on the charger, updated overnight and went to work the next day (TODAY)

    Usually, the watch lasts my whole work day. Today I was not so lucky...

    By 10AM, it's usually at 98-99% Today it was 90%. Weird
    By 12PM, it's usually at 90-95% Today it was 50%. A bit troubling.
    By 1:20PM, it's usually at 80-85%. Today it was 10%?!

    I was perplexed. I NEVER had this bad battery life using the WatchOS 2 GM, or even with 1.0.1. Yet when I updated to the official release, the next day during minor use, battery life dropped LIKE A ROCK.

    WTF happened here? I at least have AppleCare for my watch.

    We'll see tomorrow when I go back to work, same conditions, to see if it's not a fluke.

    Try unpairing/repairing?

    Give it some time.
    Mine has seen big improvement for battery life. It just used 5% over 2.5 hrs giving it nearly 2-day battery at this rate. I understand that the power draining rate may change during the day, but this is at least a 20-30% improvement over the past battery life is OS1.

    That's what I did, and now my battery life is back to normal. Been off the charger for over 7 hours and I'm at 76%. Yesterday, I was in power reserve after 4 hours off the charger.

    Ya as others are saying un-pair/re-pair... I had the exact problem you're describing but it was back on the same GM version you're talking about. Ever since i re-paired, the battery life has been the best I've seen in 4 months of ownership.

    I have the same issue. I typically could push 3 days with no charge, but by the time I got home from work it was completely dead (first time EVER) after a full charge last night. Will try unpair/repair when it gets off time out in the other room.

    Yep, same battery problem this morning, Unpairing/paring seemed to fix the problem.

    Are you guys re-pairing from a back up, or from scratch?

    Apparently unpairing/repairing is the new "restore in itunes" of the Apple watch. It fixes so many issues.

    Unpair/Repair worked for me as well.

    Before: 6% Drain per hour = 17hr life
    After: 2% Drain per hour = 50hr life

    Watch is also more responsive now, less UI lag.

    Unpair/Repair worked for me as well, instead of 10% at 1:20 PM, I was at 76 at 3:00. Guess the issue is now fixed. Thanks for the many people who suggested it.
