I've been very happy with this phone since I got it 6 months ago. I would come home after 16 hours of nearly constant Bluetooth use with 40% left. I upgraded to the latest ota update, and still had good luck. The six hours into one day of virtually no use , I was at 50%. I did a factory reset, no improvement. a 12 your day of very minimal use had me at 20%. I checked cpu spy and seen the 1690 band in almost constant use. Check attached screenshot. I decided to downgrade firmware, but had difficulty. I settled for wiping user data and cache with the recovery menu. Reboot the phone and logged back into Google to allow my apps to return. 6 hours later the phone is at 96% with an estimated 5 days remaining.B-). Screen shot attached.

I don't know if it was just the second reset, or resets should be done with the recovery menu, but it worked.

That's why a factory reset after each update is highly recommended.

Yes, but which method? Through the device is was unsuccessful. Through the recovery menu worked much better.

Both methods should work in the same way, as far as I know

Which firmware do you have?
