At first I was really pleased with this battery. He held on average much longer than my 1.5 years old original battery.
After less than 8 weeks I have to say, however, that I am disappointed plentiful. Meanwhile, I can watch as he gets weaker and weaker. Although no apps or great background applications are running.
After less than 2 months it is clearly weaker than the old Samsung battery. Disappointing because I actually brought it to me to stay than a day away from home may have to have that my phone gives up the ghost without fear.
