A few weeks back I took a look at my battery health on Coconut battery. My Mac has only been 18 weeks old and the health percentage was stunningly low at 89%! I've searched inside out the internet and found no way to repair my battery health. So ever since then I have taken two methods hoping that I can regain the lost battery health: Shutdown my mac regularly instead of put to sleep and only charge my mac when the battery percentage is lower than 20% Over a few weeks time the health has bounced back to 94%!! But I still have a question, is this temporary or permanent? p.s. for some reason the coconut battery log isn't orded in date, sorry.
