Hello everyone; I have a little problem, CoconutBattery shows extremely high Battery Power Usage just after the charge is completed, When I unplug the magsafe and plug it in again the value drops to reasonable values like 7-11 Watts. Here is a screenshot of the incident after last 6 charges. First of all, what does this "Battery Power Usage" mean? Is it the amount of power that my adapter takes from the wall plug? I use a 60 W adapter is it possible for the adapter to drain more power than it's design capacity? We had an unexpectedly high electric bill last month so I am a bit worried if this might be the reason.
