Macbook Pro 2017 13" Touchbar - Battery Suddenly dies
My Macbook's battery suddenly died, it was plugged in the whole time, and while I was using it, it went blank, and when I restarted it, the battery percentage was 1%, after leaving it plugged in, the percentage jumped from 1 to 6 and then to 20% straightaway.
My battery cycle count is only 189, but the full charge capacity has weirdly gone down to only 3100 MAh.
What do you think the problem is? Do I need a battery replacement?
