Re: Does the expandable battery fit the double case made by incip
You can use the standard battery cover instead of the extended and get it looking a little bit better. There is still a slight gap, but not as big as with the extended cover. Barely noticeable and you still get the benefit of a little more juice. I am not one for big bulky extended batteries, so I have never purchased one before.The thunderbolt I had before went from a brick to well, a bigger brick.
Case aside, I think the phone feels much better with the extended battery and cover. Its a lot better to hold and is more evenly balanced.
IMO, for the price and the little if any downsides, I don't see why you wouldn't go for it even if it is a minute difference in run time.
