Hi, I bought my MacBook Air 13” Retina 2018 almost 2 months ago, and have now a total of 22 cycles. I always let it decharge to <20% before I recharge it to 100% and then unplug it - trying to have preserve the battery life as good as possible. But after just 22 cycles I have lost almost 4 % health. Is it normal for the battery to loose a lot on the first cycles, or does this indicate a bad battery? Apple says its suppose to have 80 % left after 1000 cycles, but at this rate I will have 80 % at 100 cycles, or is this method of calculation far off? I’m soon going to have the top case replaced because of a bad Butterfly keyboard, and should I then also complain about my battery? Or is my situation normal?
Actually it’s not as bad as you may assume. I get a lot of new batteries and I’d my average for a new one is about 95%. So I would keep an eye on it for a while and see if it continues dropping at the current rate before sweating it to much.
