HTC Thunderbolt Battery Extender. Unlike many other battery extenders, model matching with Thunderbolt HTC actually built by HTC. This is a little warm and a little frustrating as a company solution for a problem that they have to make before, but life is already known.
HTC battery failure Thunderbolt achieve the level of the famous and even blamed for delays that delay the release a phone (even though no official word has leaked about the reasons behind the delay). Whatever the case, the solution is near.
A new battery is attached to the back of the Thunderbolt and stimulate the internal battery 1400mAh to 2750mAh, which is quite a leap. Although almost double the battery capacity, unable to effectively double life because of how (and how quickly) the onboard software to use the extra juice.
This battery is a bit rough (maybe it was underestimated) and weighs a full ounce, but consider the alternatives are always looking for an outlet and you have justified the sale done.
Battery holder for about $ 50 dollars, but if you do not have the dough (or do not like the design) you have a solution to your dilemma.
Both companies have worked together to fill an induction package and loosen. Basically, if the system is in use, the battery is only by putting the phone on the pillow. This is useful for home and office, but will not be exactly optimal when you are.
However, pad and battery back combo will replace the fat of the Thunderbolt HTC dimension to curb. This unit, unfortunately, sold in two parts. You have to shell out $ 30 for rear and $ 70 for filling the street.)
Another solution is to simply buy a second battery and carry around with you, but it's a bit far, do not you think?
