Posted same at Reddit but got mixed responses. I did a full charge few days ago, and when I turn on Model 3, it shows 493 KM, in percentage view it shows 100%. Today I charged to 85%, it shows percentage correct, but only 413 KM. Does Tesla consider my driving consumption while calculate the remaining mile age? Or my battery starting degrades only one month old. I know my Nissan Leaf was calculating the remaining miles according to my driving consumption previous day. I am in Canada, so I uses KM instead of Miles . Sorry.
