Please try this, charge your phone completely and when you see the 100% on the screen unplug the phone, now look at your precentage ? Does it drop to 98 ? Mine did and when i plug the phone back in it read 100... Could this be a bug or a issue with the charging wire or issue with the phone ?
 
How bright do you have your screen? A full 100% charge will never last very long when the power demand is high, like if your screen brightness is at full and/or you have blue tooth enabled.
 
I've had the same problem since before the update. Still happens currently. Even after it drops restart the phone. It should go back up to 100% and drain at a normal pace.
 
Thats a miscalibration of the battery, if it matters that much to you let it run down entirely, to the point where it no longer stays on. Then wait a few hours then charge it fully, I'd been having this "bug" for a long time now and that always fixes it.
