Here's a good video for everyone to check out that's thinking about getting the Bionic... YouTube - Motorola DROID Bionic Hands-On. Pay attention to the battery level while watching, I can't be sure but it seems to drop while watching the demo. Also, listen to the demonstrators comments on the Bionic's battery life, not to promising. I will say that Motorola phones always seem to have really good alternative battery options available for us to purchase. Whatever the case, I do not expect the Bionic to have good battery life on the stock battery. If HTC or Verizon brings out a decent alternative battery that doesn't ruin the look of the phone the Thunderbolt would be a good deal. Just something else to consider.
The battery looks pretty steady in that video. The only time it changes is when he hits the Skype app, and that must have been a pre-rendered demo because the notification bar changes to what looks like a Sense skin!
