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

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

    increased maximum charge a few days later.png
    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. ??

    It could also be that some of these apps aren't very good at calibration.

    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?
