Help Desire battery


Android Enthusiast
took it off charge at 5:40 this morning, it's now 10:50 and my battery has dropped from 100 to 86%.
I have no syncs on going, apart from xda forum app. Wifi was off as was Bluetooth. Display is on the middle setting and my screen was on for no more than a minute when I sent about two texts.

Is this drop in normal??
