I'm not seeing any of these bugs either. I am however getting terrible battery life compared to 5.0. The top battery drainers listed are google play services and android os.
I did not have spotify installed on the tablet. I fixed it by doing a factory reset via the bootloader. Seems to be okay now.
A cache wipe definitely solved my google services issue... That and deleting Fit
For those of you having problems with Google Play Services, try updating to the latest version just released today 7.3.26. Make sure you download the correct vers...
I am having the same issue with Moto x pure edition running 5.1, insane amounts of drain while the phone is idle. about 10% an hour. I'm hoping someone finds a solution
I did a cache wipe and uninstalled fit. still getting crappy battery life. loosing about 10% per hour with medium use. I used to be still at 45% by the end of the day, now i'm hitting that mid afternoon.
