I reset my phone over the weekend to see if it would improve, which as far as it shutting down around 20-30% I don't know yet. However, it is now randomly doing a reboot about once per day & my bluetooth connection issues has returned. After the December 2016 update, my bluetooth radio either wouldn't turn on, devices wouldn't connect, or they would be connected but with no audio output; this would require a reboot of the phone to get it to stop but I'd have to do this several times per day. So now this issue is back. I'm ditching this phone later this month, and not sure if I'll return to Motorola.
