So, when I put my Early 2013 on power-charge Coconut shows roughly 80.8% but when I run on battery with Logic Pro X and Saffari - it jumped all over the place as low as 40% to 78%. My cycle count is around 630 and whilst on battery it can turn off at 30% to 50% (randomly or when under load). Would this count as a fault or replacement?
I did have the service battery error message about a month ago and I spoke to Apple Support who jumped onto my machine remotely and confirmed it, but I didn't chase it up at the store.
