My Note 3 battery was totally dead bcz I dropped it into water, by accident. So I did some research and compare, ordered a replacement from mpj. Received it a week later but this battery, which suppose to be an extended one, is not an improvement---not lasting even one full day. Upon hearing about my experience, they sent me a new battery to exchange for the first one. Waited another week, and thankfully the new one works wonderfully and holds a charge as it should.
