I can't really roll back my 950XL to 8.1
After getting my new Lumia 950 this week and not enrolling it in the Insider program, I went 24 hours from Saturday to Sunday, including a 30 minute GPS run and sleep tracking, and still had 34% battery left when I finally plugged it in to recharge.
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.
Has anyone tried the 14393.82 cumulative update that is in the Release Preview ring to see if it fixes the battery drain?
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.

Improved battery life of wearable devices (such as the Microsoft Band) while Bluetooth is connected and idle.
Just saw the article about build 14393.103 entering Release Preview, with this item in the changelog as well:
Hopefully that should fix at least one huuuuuge issue, even if it doesn't fix the live tile of the MS Health app.
i can confirm my band2 battery lasts about 2 days again after the .109 update. pretty happy with that now!
