Greetings!
My M1 MacBook Air is at 80% battery health,
and I need a new battery before my AppleCare ends so I can hand it down in perfect condition and battery as well so it lasts a long time for the next person.
According to the BatteryBDC folder, it literally was SO CLOSE to reaching 79, but the battery health decided to go up.

Any ideas on how I can get my MacBook to 79?
I tried an app that stresses your CPU for no reason, along with auto clicking in Roblox, and that did not work... all it did was go up...
Looking forward to any responses,
Sincerely Will.
I had this problem a few months back. I'm running a 2020 Intel MacBook Pro and my 3 year AppleCare was down to the last few weeks. Using Coconut Battery, it showed that my battery health was constantly moving between 79.4% to 83%. Very annoying.
What I did was to run the Mac on battery, and then constantly run Handbrake and convert the same six .mov Quicktime files to mp4 until I drained the battery to below 10%, often going to 5% or lower. Then I recharge it back up, and do the Handbrake conversions again. Rinse and repeat. I did this on and off for maybe 3 weeks leading up to the end of AppleCare coverage, and I got in maybe 80-90 battery cycles during that time.
I made an appointment and took it to an Apple Store (this is in Shanghai, China where I lived at the time) on the evening of the last day the AppleCare coverage was valid. Before I went, Coconut Battery showed the battery was just below 80%, at maybe 79.8% or something like that. When I got to the Apple Store and was waiting my turn to talk to the Genius, Coconut Battery showed the battery was above 80% again. I just felt so deflated. But I was already there, so I went through the process.
The Genius came, checked it out with their gear and software, and eventually he came back and told me the battery was at like 81% or something like that, so it doens't qualify under their rules for the battery replacement. However, he added that he feels the battery could go under 80% at any time soon, perhaps as soon as tomorrow right after the coverage expires. He doesn't want that to happen, so he said he would apply for his manager's permission to allow him to replace the battery anyways, which might take a few days due to parts availability or the waiting list, etc. I thanked him.
He came back later and said his manager gave him permission to do so, and he said since the coverage ends tonight, they can't put my Mac in the queue to replace the battery in a few days, due to whatever Apple policies. Therefore, as an added bonus for me, they prioritized replacing the battery (which he said also includes replacing the whole top half of the MacBook Pro as they're soldered together) and I can pick it up tomorrow morning.
That is exactly what happened: I got a text message the next morning that it was ready for pick-up, and the whole top half of the MacBook Pro was replaced as the keyboard looked new when I got it back.
Whether what I did would work for you, I don't know, but that's my story.
