Plugged in

Is it safe to keep the MBA charger plugged in 95% of the time?

I never found it to be a problem on my 2011 MBA. When I sold it over the summer, it still got very good battery life. Am doing the same thing with my 2013 MBA (spends most of its life connected to a big screen and keyboard). But every now and then I let it run down on to exercise the battery.

You will be fine. Just run it on battery once in a while to exercise the battery.
