Re: HTC Evo 4G 3500mAh Extended Battery + Cover $12.99 AMAZON
I have this battery (using it for a couple of months), and it works better than stock. If I leave it on 3G, and use it a lot, I still have plenty of juice left by bed time. Not so much if I use 4G, and leave the 4G radio on. I'm using CM7 final. But for the price, it can't be beat. I'm happy with my purchase.
