Hey sorry for bringing up old discussions. I just recently upgraded to an HTC Thunderbolt (since this was the only free phone that looked good) but i am very happy with my decision. I am really loving this phone. Before I got the phone, i read reviews about how the battery life on this phone sucked and i do agree so I purchased the Rezound battery. I heard it improved the usage time of the phone but there is one concern that i have. Sorry if this may be a dumb question but i really don't want to mess up my phone. Can I charge my rezound battery when it's inside my HTC Thunderbolt or would it best to get a separate wall charger for the phone? I also bought this charger for the rezound battery in case http://www.amazon.com/Battery-Deskt...ncredible/dp/B0054U58OY/ref=pd_bxgy_cps_img_b I read that it is compatible with rezound battery but i guess i want a good confirmation with you guys to hear that I am able to charge the rezound battery while it's connected to my phone. Thanks everyone who is able to help.
