I bought a MacBook Pro 2020 and in 6months, it dropped to 88% percent in design capacity with only 42 cycles. I rarely use my Mac and it worries me, is it normal or should I go check with apple support. I have even turn on optimised battery charging and manage battery longevity. Thank you for time:)

Apple says that your battery should last for at least 1000 cycles and maintain at least 80% of its original capacity. However I have used Coconut Battery on several laptops and on one, a 2010 Macbook Air, the capacity actually INCREASED after initially showing a decrease that seemed alarming. It is presently at about 85% but had been as low as 80%. My conclusion is that utilities like Coconut Battery (and Apple's own About This Mac => System Report = Power) are not especially precise and have some "noise" in them. If your battery reduces to less than 80% prematurely while under warranty (or extended warranty), I believe Apple will replace the battery for you.
