I didn't see if this was mentioned, but I recently purchased the HTC Rezound for my wife and ordered another battery from VZW for $19.99, I put that battery in my Thunderbolt and it works great. Even with daily usage from medium to heavy, getting at least 14-20 hours of battery life. Iam running a rooted Tbolt and I'm using Skyraider rom and it is great. The phone should have been released with this battery. I have used the bigger extended battery and hated the extra size. Sure it is easy to hold in the hand, but that is just the trade off for having better phone life.
If you love your Tbolt and can't get an upgrade soon, order this battery. You will not be disappointed.
