My phone was not acting very smart. My battery needed charging during a half day of use. I was puzzled and even contacted AT&T and found that an OEM battery from them would cost $40.00. I figured my phone was old and I would upgrade. Then I decided to check Amazon for an OEM comparison. I found a battery for $5.99. I paid the small freight charge ($2.99). After installing the battery and fully charging it, I now have a phone that can run for at least 2 days of normal use without a charge. It is amazing how good and inexspensive this battery is and the best part it is an OEM.
