One of the biggest issues we saw with the Verizon ThunderBolt was the impact LTE could have on battery life: turn on the mobile hotspot functionality, for instance, and you could expect your smartphone to be drained within just a few hours. Verizon's new ThunderBolt Inductive Battery Cover isn't going to add any extra mAh to the handset, but it should make topping it up a little easier.
The replacement battery cover popped up on Verizon's site recently, priced at $39.99. The "buy now" button doesn't actually do anything at present - just take you back to the homescreen - but we're guessing that will change in the near future.
Technical details are scant, so it's not entirely clear which method of inductive charging HTC and Verizon have picked.
