Got it. I just tried it and it went up from 65% to 67%. Unfortunately for me, with v. v. minimal use it's already down to 64% in 3-4mins of reading up on this code...
OK, got it. I'll try the same. Are you using any battery calibration/tool apps as well? (I'm not, but just wondering..)
did you just typed the code in the dial pad and then left the screen after? Or did you click on "quick" button at the bottom as well?
For those with battery issues, did you guys ever booted into safemode? Safemode seems to be a way to reset Android to default, and meanwhile allows you to compare if it may be app related causing the drain.
To get into safe mode, power off device, turn on the device, and then repeatly keep hitting the volume down key continiously. If it is successful once you boot into android, bottom left will say safe mode.
