I charged my controllers for 15 hours and the charger + controller were still warm..
That means that the controller thinks the battery need to be charged even though it's fully charged. (my guess, the firmware update have some kind of missmatch to the sensor that reads battery status)
Meaning that if you having the charger on for more then fully charge time you will wear out the capacity of the battery.
Meaning you will not be able to play for longer period of time because of low capacity.
HTC will need to open up for replacement batteries in one year or so :)
