It’s no secret that part of the delay of the Verizon HTC Thunderbolt release was do to the challenging battery life of the handset on the 4G/LTE network. In SlashGear’s review today, that was never more obvious when solely relying on 4G for average use, the Thunderbolt red barred after less than 3 hours. And even though coupling 4G with WiFi the battery life becomes comparable with other HTC 4G options, clearly something needs to be done. HTC is addressing battery life concerns by announcing they will be selling an optional extended life battery in the near future.

“We want customers who are power users, that are going to have the hotspot on all day, to just go,” said Pat Bucci, Verizon’s director of accessory products.

The new battery, which will cost $49.99, nearly doubles it’s mille amp hours from 1400 mAh to 2750 mAh. But that extra boost comes at a cost because it will add another ounce to an already hefty 6.23 oz handset. And the Thunderbolt will also have to deal with being thicker as the larger battery means a new backing that will come with the battery. There is no word if that new backing will also eliminate the hefty metal kickstand that is built in.

In addition to the new extended battery, Verizon will also be offering a charging dock for $59.99 that can charge both the phone and a backup standard or extended battery in concert. A second standard battery will run about $30. Another option takes advantage of the Thunderbolt being the first Verizon phone that supports wireless charging. The optional Qi-compatible back and charging pad will set users back $29 for the Qi back and another $70 for the charging pad. Geez, that’s a lot of money to address an obvious battery life flaw.
