I bought this battery because the OEM one that came with the phone died completely. There's not much to say, it fit my phone perfectly and had enough juice to at least turn the phone on so I could see what calls I missed. Now that I've used if for a month or so though, I do feel like this battery drains faster than the OEM and that's kinda weird seeing as how this is a 1250mAh and the OEM one I had was 1150mAh. Overall though, I'm very pleased with this purchase and would recommend it to anyone looking to replace their phone's battery.
