Hi, I have had this MacBook Air M1 for a little over a month, and after only 14 cycles maximum capacity dropped by 2%. I was also trying to keep it between 20-80%. I don't know if this is a problem with this MacBook or with all MacBooks. Or is this normal? I have had my iPhone Pro Max 14 for 4 months and my battery capacity is 99%, which I use and charge every day so this seems way too fast.

That Mac's battery condition is normal. There is nothing wrong with it.
I was also trying to keep it between 20-80%.
You don't need to concern yourself with that kind of minutia, and it won't help anyway.
Battery capacity will fluctuate over short periods of time. They start at 100% capacity and will not increase from there, nor will they ever return to 100%. That Mac battery's maximum charge capacity of 98% may increase, and it may decrease, although the long term trend measured over a period of years is down.
