Fortunately, some light has been shed on the issue by a leak straight from Verizon's inventory. From what the rumor suggests, the HTC ThunderBolt will probably get an optional beefier battery with nearly double the capacity of the stock one. Spending $50 on one of them might turn out to be a good idea if the LTE radio turns out to drain more juice than one would expect. Another potentially useful accessory may be a multimedia dock, which will also have the capability of charging an additional battery besides the one inside of the HTC ThunderBolt. Speaking of charging and batteries, a special battery cover is expected to retail around $40 and will allow your smartphone to charge wirelessly though it isn't exactly clear how much more you will have to spend on a compatible charging station.
The rest of the accessories, holsters and cases for the HTC ThunderBolt, are not really that special. However, to us it seems like Verizon is making sure we have plenty of options to choose from when it comes to charging the HTC ThunderBolt. Could this be a hint regarding the smartphone's battery performance?
