When it comes to extended batteries, there are a couple things I worry about. First and foremost is having more juice. That's a given, though. With the 2750mAh extended battery for the HTC ThunderBolt, you're getting nearly double the miliAmp/hours of the stock 1400mAh battery. So it's going to last longer. (Or in the case of the ThunderBolt on LTE, which sucks through a battery, you might actually get a day's use out of it.)
But the other thing -- and for a lot of us the only real concern -- is how the extended battery looks and feels on the phone.
First things first: It's bigger. Along with the battery, you get a new battery cover. And the cover has the same cutouts for the camera, dual flashes and 3.5mm as the standard battery. And it also has the same internal antenna connections, which is important, too. It's also made of the same soft-touch plastic as the stock battery cover and has the same HTC and 4G LTE markings.
As for the size, it's definitely larger, sticking out from the back of the ThunderBolt, whereas the stock battery and cover are flush. That's to be expected, of course. Funny thing is, it doesn't feel too bad in the hand. It's noticeably heavier -- about 1 ounce -- but, again, that's to be expected. But our fingers rest comfortably on the top lip. So despite the added size and weight, it's not horrible.
We'll talk actual battery life once it's broken in and properly tested. But for a good look at how it'll fit on your ThunderBolt, hit the pictures after the break. You can snag the HTC ThunderBolt extended battery in the Android Central Store for $49.95.
