Unfortunately, not satisfied at all. 0 Stars!

1. The battery I received did not have the Samsung logo on it. I thought about returning it but since I had a trip to make and was in a hurry, I decided to try it out.
2. The battery life after just 1 month of use is worse than the original one I had for 4 years... that says it all! I charge it at least 3 times a day and I always carry a power bank with me.
3. It heats up easily
4. My device has given me a warning twice with the new battery that the battery is depleting quickly and that I should take the phone for inspection and possible replacement. This message never appeared with the first battery that came with the phone....

I have nothing more to add.

The only positive is that I got it very cheap but in the end it doesn't matter because it's useless! That alone should have made me think twice....
