2020 M1 Mac Battery

[Jb25]

In around February this year i bought a brand new Macbook pro, with at the moment with only 121 cycles, the battery health capacity is at 92%. When i am reading online 500 cycles should get a mac down to 90%. I have also been checking it every few days and it seems to go down now around a percent a week.
So, is this a software issue and something that i can fix by resetting something, or is it an issue with hardware and something wrong with the computer itself.

My MacBookAir (Early 2014) has a cycle count of 359 and is at 86%.

What is your charging routine do you run the battery right down before charging or do your charge when partially drained?

I usually run battery till around 30% and then normally back up to around 95%.
