This phone does NOT come stock out of the box optimized for battery life but you can make some adjustments to improve it for yourself. This is something that falls on the USER if you expected 8-10 hours of battery you let yourself down by not doing enough research on this phone so please stop blaming HTC or Verizon for something that will improve if you put forth some effort and hopefully more so with software update to tweak things we can't adjust that do need mild improvements.
<em>Stop putting the blame or task or what ever you want to call it on the User!</em> It's the manufacturer's fault for not supplying a proper battery and that is that!
I contacted HTC and provided them with list of complaints about the battery life and here is their response.
Thank you for contacting HTC Technical Assistance concerning the battery for the Verizon Thunderbolt. The Thunderbolt came with the 1400 mAh battery. HTC Technical Assistance is not aware of an extended life battery for this HTC Device. There is currently not an option to change the battery that came with the device. Please feel free to research information at the websites I have provided below to obtain information on a different battery that might be available for your device.
