There is a lot more to battery life than how much we pace, it has to do with the extra features we use and the safety margins. The length of time left on the battery is just an estimate and it will vary from check up to check up. It doesn't mean it has exactly 6 years left, it means at the current usage and settings it would have 6 years left. They often start them with very high safety margins which use up battery life faster, then they gradually fine tune the settings. So, it may last 6, it may last 10. I don't pay much attention until it gets down to the last year.
