What do we need...MORE POWER!!!!

Wow... That is quite the battery cover... It looks like a square headed android face without facial features... Maybe they should add two beedy little eyes to it.
 
Uh thanks but no thanks, Ill pass. Already getting 13-16 hours, thats enough for me.
 
I bought my EVO to use it, not to admire the looks. Plus, this new back cover looks like it will protect the camera lens very well, by keeping it above whatever surface you lay the phone on.

My only concern is the price. $70 is a lot of cash, and the stock battery isn't all that bad. I'll probably get one when it comes out, but I'll have to think about it.
 
I understand that performance is what you want....but at what price. Some things are too hideous to bother with. This is one of them.
 
It says under the extended back that its still just a concept design. But that thing is huge I wanna wait till someone gets it and see howe they like it first.
 
I've ran the Seidio 3500 battery on every phone I've owned in the last few years and will definitely get one for my Evo when I get it as well.
 
A standard size ~2000mah battery (actual tested mah, that is) to just extend the EVO to a good, full day would probably fit most users needs.

BTW battery engineers, what the hell happened to those great fuel cell phone batteries that were suppose to get a week's use per charge?!? Screw flying cars, give me my dang long lasting battery!!!
