Though this battery is startlingly inexpensive (and therefore probably still worth the price, just barely), mine doesn't hold much of a charge. I charged it at least 24 hours (and maybe more like 36) when I first got it, but still I don't think it gives more than an hour of talk time. Also, it's hard to gauge how much charge is left, because (unlike my original battery) the first two or three bars on the indicator disappear far more quickly than the fourth.
