On the 22nd of November my battery health was at 91% and 312 charges. Now on the 12th of december at 328 charges its at 90%. Is this unsual because it should go down every 50 charges.

Is this unsual (unusual) because it should go down every 50 charges.
Apple always rounds down any tenths of a percent to a whole number. So, let say that 91% was really that....91.0%.
So, the battery might have declined to 90.9%.....a drop of only .1%, but Apple will display this as 90%. So to you it looks like the battery declined 1% in a very short period of time......when it might have really only declined .1%.
You are going to drive yourself crazy if you are checking the battery settings constantly. Don't try to babysit the battery, it won't help.
Battery health degrading faster than expected
