This has got to be the biggest piece of junk I've gotten from Amazon. It can't even pretend to be an oem battery because it looks nothing like the real oem, if fact it's so shoddily made that nobody even put a logo on it. I wouldn't either if my factory was turning out this garbage. It's a battery, so how bad could it be? Well, for starters, it's obviously too small and doesn't make good contact with the pins inside the phone. You move the phone at all and it powers down. So, it's kind of hard to even judge whether it's a decent battery electrically since it won't keep the phone powered reliably. (and no, the real oem battery didn't have this issue in the phone) Total junk. Avoid seller Cellular4all.I'd return this thing, except at the price it's not worth my time.
