Hi all, I bought a 2016 gold MacBook last February, and the battery life is now around 90% with 66 cycles. I am wondering if this is normal, because it seems kind of rapid to me. I uploaded pictures. I'm considering taking it in as the X key is no longer functioning at 100% (a sad, common issue with these keyboards), and I want to know if I should ask them to check the battery or replace it. Thanks!
