    Hi guys, I have no idea why this is happening. The screenshots basically say all that needs to be said. I'm on a 2013 13" i7 8gb MBA.

    Memory usage looks okay there... show us what is in the CPU tab in Activity Monitor.

    Unless you are watching a HD movie at this moment, a little over three hour projected battery life is way low.

    If you click on the "Energy" tab in Activity Monitor, it will reveal the energy impact of various apps.
    The CPU tab cannot be empty, as there are always processes running.

    I said "essentially". I'm a software engineer, I know my way around a computer, I'm just showing proof that this is an exceptional circumstance since all signs point to OK battery life, but it's still being eaten up fast.

    On a forum, it is impossible to know in advance the knowledge or experience level of other posters without prior interaction. You still haven't indicated what the CPU or Energy tabs show. "Exceptional circumstances" are relatively rare. Much more common are issues that simply require a bit of troubleshooting.

    Nothing obvious wrong there. :confused:

    Try a safe mode boot and see what that does for the battery life readings. Safe mode is a stripped down boot that bypasses all startup/login items so will eliminate those as the issue. (I see you have quite a few like Dropbox etc)

    Did this start after 10.9.3 update?

    I have the same configuration and after the update, my battery drains more quickly. No problem while sleeping, about 2% overnight, but drains rather quickly just surfing the net or syncing iphone.

    Don't cloud syncing storage services like Dropbox and Google drive kill battery life?

    Googling "dropbox macbook battery life" brings up quite a few results suggesting this.
