Anyone using an extended battery? I noticed a Mugen powered battery (1600mAh) that's the same size as the stock battery for the Fascinate but has 100mAh more power. Anyone use or recommend this one, or maybe any other larger batteries that don't require a huge backing for the phone?

Could it be because I flashed a new rom on it?
