Let's look at this realistically... You just bought this car. Also, you have a 3 year warrantee..
1) The battery has not even been used yet, you are only now STARTING to exercise the battery. There may be some fluctuation in the battery when brand new.
2) Gauges and meters are NOT precise measures of any aspect of what is measured... They are only a general indicator.
3) You are a new buyer, and are paranoid that you will find a problem!!! Relax, observe and note what is a real indicator of a problem... If your Battery % goes from 100 to 99, or 98%... Then keep an eye on it. It will never be an exact measure.
4) And when you get LEAFSPY.. Don't go crazy when the car gauges don't match EXACTLY with leafspy... THEY WILL NOT..
PS - congratulations on your new car.
