I replaced the battery of my macbook pro 15" mid 2015 with a replacement from ifixit after it gave a recommendation to replace it and the battery life was terrible. No other issues with it. The macbook did it perfect for a few days and I was able to recharge it fully about 3 to 5 times. Suddenly I have power issues with the following symptoms: won’t boot when on batteryon charger it will startup, but after login it will restart when bar hits around 30%I managed once to somehow get in a few days later. Battery was charged to full and I tried again. No adapter. There was no error message about the battery, everything acted normally.Next day, same problems again. The thing which keeps popping in my head is that the voltage on the replacement battery was lower then the original battery. But the labeling of the battery said it was exactly for my model. Any idea what I could do?
Hi My advise would be to plug the old battery back in and see if the issue persists If it goes away try cleaning the board and battery contacts with isopropyl alcohol If the issue still persists contact ifixit there support team is amazing and will give you some of the best support out there Thanks:)
