    Has anyone else experienced system choppiness when the battery gets below 5% on the late 2013 13" rMBP? Scrolling seems to stutter a lot more in my web browser. I also notice that SystemUIServer starts taking a lot more CPU % than it normally does. Is this normal? The moment I connect the power adapter to the laptop it returns to normal. :confused:

    It's probably throttling heavily in order to last as long as possible so you can save your work and whatnot.

    It happened to me last night!
    I was playing trine and as soon as my computer went to 5% the game became unplayable, connected it to the power a voila everything was smooth again!

    Maybe some kind of throttling going on to save battery!

    At 5% it's advisable that you either start recharging or stop any task at hand. As to why the performance becomes choppy at that point, it's both academic and redundant.
