Same issue here, I took my computer to a store ( not Apple ) to get the battery replaced ( and I guess they probably got the new battery from iFixit ). Noticed this issue and immediately thought he installed some knock-off battery. I took the computer again, picked it up and I was told there were no issue anymore and that they re-replaced the battery. Still the same problem, what should I do? Honestly I don’t think they’re gonna fix it. They’ll probably find some excuse. I’m thinking of taking it to Apple Store and ask for a refund. Any advice? I waisted 2 weeks over this thing already.
