    What do you do then? Open Activity Monitor and select All Processes and then sort by CPU to show you the process(es) eating your battery life.

    Just did that. It was pretty ordinary. iTunes and Chrome ~5% each, finder 8% and Messages 5%.

    Make sure you're looking at "All Processes" and not "My Processes". There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.

    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

    Plus when on battery power turn down your monitor brightness. This will extend your battery life.

    Thanks. "Locum" was taking up a lot of power . I think it is the trash emptying process.

    That and the calendar app "Fantastical"

    It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the Apple Notebook Battery FAQ.
