    I've had the band 2 for approx 6 months now. The battery life could get me through a little over a day in the beginning. Now, I can't even get through half a day and it is dead. I turn off the bluetooth and it still has crappy battery life.

    Anybody else having this issue?

    FWIW - I did originally have a L1520, but I got a Gs7 edge when they came out.

    I switch from a Band 1 to a Band 2 right after the Hiking update came out.

    I don't have any previous Band 2 experience to compare to, but it does seem to drain quicker overnight, when in sleep tracking mode than the v1 did.

    I have noticed that my band rarely lasts a day now. I charge it every night while I sleep, and it used to always make it. Now, I almost always get the "battery low needs charging" notification sometime between 6pm and 9pm. Occasionally, it will make it. I have the clock set to turn on when I turn my wrist, which is a change for me. Before, I had it set to always on and it still lasted the entire day.

    Mine seems ok but I only turn on BT when I want to sync data, which is once every few days. Watch mode is off.

    For what it's worth, the battery life on my Android phone and the Band 2 went down after the last update. I went into the app and noticed that it was set to sync every 15 minutes. I don't even recall that option being available in the past but it was there now and was syncing every 15 minutes. The sync now seems to take longer so I'm sure it was constantly draining battery.

    I switched my sync to every 4 hours instead and things went back to normal. I don't need it to sync that often anyway so I'd rather have battery life vs. up to the minute data on my phone/Microsoft Health Dashboard.

    Hope that helps someone else!

    Well, My second Band 2 just died. Yes battery has been awful pretty much since I got it (3 months ago), 30 hrs at beginning, and for like the past months it was lucky to get 24 hrs.

    This second Band 2 died by slowly tearing at both sides of the clasp. First one I owned three months and that one died in the same manner. This one also lasted 3 months.

    My Band history:
    Band 1- Oct '14 - Summer 15. Clasp Broke completely off. Great battery life though- nearly 40 hrs. Warranty Replaced
    Band 1- Summer 15-December '15. Stopped working one day completely. Battery was okay- 36ish hours. Warranty Replaced.
    Band 1- December 15- Sold new in box on ebay to help pay for Band 2.
    Band 2- December 15-March '16. Started with great battery, matching my Band 1's. But after about 6 weeks it went to S***. 24 hrs was hard to come by plus the rubber clasp was tearing. Warranty replaced.
    Band 2- March '16-Today(June '16)- Battery started okay (30ish hrs), quickly fell to 20-24 hrs.

    So I'm off to local MS store, where I'm sure they'll once again make me ship it and have me wait weeks for replacement.

    I like the software and the features, so I'll probably buy Band 3. But the choice of battery supplier and the material selection for this product was a huge miss. At least they have the decency to honor standard 1 year warranty.
    I like to make fun of how useless my gf's apple watch is for health but at least it looks like new after 6 months of use, meanwhile here I am heading to get my third Band 2.

    Nice catch on that! I hadn't noticed that new setting either. Heck, you can always sync on demand if you need it, 4 hours is fine.

    This in the android version, don't know about WP or IOS: In the preferences section, right at the bottom, you'll find 'Sync Settings'.

    Mine was set on 10mins, but this didn't seem to affect the battery much as I hadn't noticed a difference.

    I charge mine while I read in bed before I set the sleep tracking, and while a wash in the morning.

    I have now set mine to 1hour though, I don't need it that up to date and the sync seems to start when the health app is opened anyway.

    I just wanted to share, I have Win10 phone, recent purchaser of the Band 2. Thanks for the tips so far. I just wanted to add something that I am going to try. The sync referred to on WP might be under Background Apps and the option to turn off background on the Health app might help. I am still able to manually sync when I go into the app. I will let you know if any improvement.

    I'm thinking disabling the background on the Health app might disable all your notifications on the Band, though I'm not sure.

    (of course, does it really matter if the notifications hardly ever work anyway...)

    I have the lumia 950xl. What I have noticed is that most of the time, I am able to receive notifications. The rare times that I am able to reply back using the text message function on my band 2 (and when cortana is able to connect to my phone), my batter life on my band rapidly drains and my band 2 screen gets warm.

    When the text message function and corana does not work (stuck on the connecting screen), my batter life is more normal (24-32 hours a charge)

    Anyone else notice this?
