My old battery in my macbook pro late 2012 was not holding a charge very well anymore so I bought a new battery. At night when I put it to sleep, it loses at least 10-12%. It goes from 100% and when I wake it up in the AM, it's down to 89%. Is this normal?? I talked with Apple and they said I need to buy a battery from them. The battery I bought is for this computer, brand new. This is what the old battery was doing so that's why I bought a new one. But doing the same thing. I just don't believe that I need to spend a lot of money buying from them. Maybe it's true?? I don't know.
