Verizon hasn’t officially announced date of launch of new HTC Droid Incredible 4G, but HTC launched 2 extended batteries for that 4G  smartphone. The first extended battery has 2,150 mAh and costs $35, second one is a cover battery for the  HTC Droid 4G phone and price of that battery is $20. We recommend this battery to all users that are planning to buy HTC Droid 4G, because its battery has only 1,700 mAh, and if you are planning to use 4G LTE you will really need extended battery because extended batteries will certainly provide you few extra hours of battery life. Both batteries are available on the HTCpedia, retailer of HTC accessories.
