A few days ago, my iPhone’s maximum battery capacity was 2978 mAh.

Today, my iPhone’s maximum battery capacity was 3016 mAh.

Anyone have any theories?

Thermal expansion perhaps? The battery was warmer today (note the temperature difference).

Could be that it wasn't at 100% yet, like the one from the other day, and it's an estimate. ??

I agree with both of your assessments; is this (Maximum Charge) a value that the OS polls the battery to obtain, or is this a variable that the OS computes based on available data?
