Even though I did full charges and discharges for the first week or so to condition it, this battery does not seem to give me as long a life as the original battery. Also, witht he old battery, I get 20 minutes talk time once the phone indicates a low battery condition. With this battery, I get about 3 minutes warning, if that. For $4, I guess I can't complain, but I expected a little more.Update. After about 4 months, the battery completely died. I wanted to knock this down to 1 star, but they would not allow it. Be smart, buy the extra life bubble battery and cover.Unless you like to throw your money into the trash can, AVOID at all costs.
