This is my Battery usage Times from the new battery i got for my droid X it is a Ext. battery No. BH6X an has the new DX2 cover on the back. i condition the battery by fully charging it an then running it down to were the red led light comes on an it has been doing very good between charges. Way better than the battery it re-placed wich was also a Ext. battery.
