    1- If i just keep the external HDDD plugged in all the time..(not use it,just keep plugged in), does my macbook air use more battery than otherwise?

    2- I use a thunderbolt to ethernet connector..I turn off wifi because i use wired internet using this connector.does macbook air use more battery because it uses a thunderbolt and ethernet..when compared to no thunderbolt and just WIFI ?

    3- If i keep the earphone plugged in and not use out, does macbook air use more battery than otherwise?

    thank you, trying to educate myself :)

    Yes, because your external drive draws power from your MBA and hence it'll take a small hit on your battery life.

    I think the difference would be negligible.
