The battery was not lasting very long.
It went great, I really took my time and was very careful. It was a lot more in depth then I expected. You have to take out the motherboard, speaker system and the battery was glued down.
At first I took the top off just to see where the battery was. It was right there so I assumed that it would just pop out without issue. But it was really glued down tight. Just have patience don't rush just take your time.
