Battery drain at idle after Cyan and 8.1 tag team

turn off location, wifi sense, stop using cortana, change email settings, set its frequency to anything except "based on..."

I had this after updating to 8.1 but I found my email would be constantly syncing and was draining my battery in 4 hours. I did soft reset to stop It from syncing then deleted the account then re installed and everything went back to normal and i now get over a days life again. Hope this helps

I did a hard reset back to factory defaults after ensuring I had everything backed up and I I can say that it solved my issue of severe battery drain. After the Cyan update, I was only getting 6 hours of battery with no use and only 3-4 hours with normal use. Now I am back to lasting a full day and sometimes with battery to spare

I think this is worth a check for those with issues. I am not having any problems since cyan myself but I have heard of this fixing battery drain issues.

I have 3 push email accounts, wifi, Bluetooth and LTE turned on. Cortana pinned to the start screen and several apps allowed to run in the background. I easily get over 24 hours per charge. More like 36.
