HTC Desire Battery Calibration
Update: You may want to read this (Specially the bump charging part) before you move forward. My HTC Desire's charge would drop to 93%, 91% or 90% very quickly after removing from the AC charger. I came to this post on xda-developers.com that help me fixed the problem. http://forum.xda-developers.com/showpost.php?p=7690163&postcount=1 Basically all you have to do is: Charge your phone until the notification led is green. Disconnect the charger. Power off the phone. Reconnect the charger. Charge until the notification led is green. Disconnect the charger. Power on the phone. Power off the phone again, once its powered on completely. Reconnect the charger until the notification led is green. Disconnect the charger power it on and use it.
