20 - 30 minutos
My former battery needed to be charged everyday
The repair went well. It took like 30mins. The description to remove the cliped connector (number 3, i think) wasn't enough, I had to check on a youtube video to be sure. But the new battery doesn't seem to be lasting as long as the original one...
The suction cup is a must have! It really takes some strenght to get the screen out.
