    Hi guys, I just want to confirm your suspicions. Battery life went down from almost two days to barely one day. It happened after the new Anniversary update.

    Has anyone tried the 14393.82 cumulative update that is in the Release Preview ring to see if it fixes the battery drain?

    As previously stated in this thread, my Band 2's battery life became was really bad (about 14 hours) since I upgraded my 640 XL to the Redstone builds on Insider about 2 months ago. I wasn't sure of the correlation because that is about the same time that I had to get a warranty replacement because of a loose connection in the wrist strap where it would suddenly die with a full battery. At first, I thought the refurbished replacement unit had a bad battery until I received a second replacement (new in box from a retail store) and had the same problem with short battery life.

    After spending the last week before the official Anniversary Update release with a brand new Lumia 950 on the 10586.x builds, I saw my Band 2's battery life return to about 30 hours. That is about what I got with watch mode (rotate on), using sleep mode at night, and tracking a 30 minute to hour run workout with GPS.

    I installed the Anniversary Update on August 9, and currently running 14393.67. I haven't had any battery issue with the Band since the official update was released. When on the Insider program, I would have about 40% battery left after a 9 hour work day. Since the official Anniversary Update, I've had about 72% battery after work with the same usage.

    That makes me wonder if there is a different version of the Microsoft Health app that is being pushed to Insiders that handles refreshing differently.

    I'm on the official release of the AU (14393.67) as well on a L950XL now, and still massive battery drain. So it's not necessarily a difference in apps.

    Yes I have, and no it doesn't fix it. I've been testing & giving feedback on this issue since it first showed up in earlier 143xx builds, and 14393.82 hasn't fixed it.

    See also https://www.reddit.com/r/MicrosoftBa..._10_au/d6b0kvp where I go into more detail.

    So I just read that AT&T has started the push of the Anniversary Update. Does anybody know how to prevent it from being installed?

    Is it possible that the issue is lingering from previous builds that were installed on your phone? Since my Lumia 950 was practically brand new when the Anniversary Update was released, I went ahead and performed a master reset after the upgrade for a clean installation.

    Ideally, a reset shouldn't be required after an upgrade, but that has become my common practice with a major OS change over the past year.

    I have a Lumia 950 that I bought in June. I have never installed any insider builds on it. Yesterday I upgraded it to the AU. Today, I found out my band's battery had drained after more or less 14 hours of use. This is dramatically less than what I had the days and weeks before.

    It is high time for Microsoft to a) acknowledge this issue and b) provide a solution for it.

    And no, I will NOT do a hard reset of my phone only to find out it did not change anything.
    I can understand this may be needed from time to time if you're running insider builds, but it should not be required for phones with production builds only.

    Just saw the article about build 14393.103 entering Release Preview, with this item in the changelog as well:

    Improved battery life of wearable devices (such as the Microsoft Band) while Bluetooth is connected and idle.
    Hopefully that should fix at least one huuuuuge issue, even if it doesn't fix the live tile of the MS Health app.

    I was coming here to update the thread with this information as well. Since I no longer want to enroll my main phone in the Insider program, does anyone know the average time between when a build hits the release ring and when it is made available to the general public?

    Usually not too long. A week, maybe two I believe.

    Curious how long we on the production update schedule will have to wait? My Band 2 doesn't last all day now.

    Since 14393.103 I noticed I didn't have to worry about the band battery as much anymore. Probably back to threshold levels. They specifically mentioned band2 bluetooth on the release notes and they came through on it.

    Lumia 550. Windows 10 version 14393.67. Had to factory reset my phone last week. Before reset, Band 2 would get 48-50 hours, but after reset, Band 2 battery life has been cut to less than 24 hours. Has MSFT acknowledged the issue with the latest Windows 10 version?

    Mentioned in post #36 of this thread - Microsoft acknowledged the issue with build 14393.103 released to the Slow and Release Insider rings about 3 weeks ago, but you have the latest build available to non-Insiders.

    Improved battery life of wearable devices (such as the Microsoft Band) while Bluetooth is connected and idle.

    Should be fixed now for non-Insiders as well if you update to 14393.189.

    Yes, 14393.189 has solved this problem. I confirm!!! Unfortunately Weather tile, SMS typing and voice commands still do not work with Windows 10 Mobile and MS Band 2.

    My Band's battery life was cut down to a day after the anniversary update. I suspected that the Band and my Lumia 950 were communicating more frequently, but it didn't seem to have a meaningful impact on notifications. It was the Health app update last Thursday that seems to finally fix Bluetooth functionality, but the excessive battery drain seemed to persist.

    I now have the Band paired with my iPhone 7 and battery life is back up to 2 days. Notifications also work more reliably than they ever did on the 950. Except, of course, for the aforementioned update on the last day I was using that phone.
