I'm in need of a new battery, I'm only getting 4 hours of moderate use off the one I have now. I bought my OG Droid off a friend of mine's girlfriend, and I'm pretty sure it's the original battery that came with it. I was thinking it was the ROM, but after several changes I really see the same amount of discharge for each. So what do you guys suggest for this broke college grad? Like the mah and what not? I'm not exactly sure what to look for in a battery.
