Both of these depend on the climate primarily, and to probably to a lesser degree charging habits and mileage. And then there are calendar losses (over time).
viewtopic.php?p=545757#p545757 is in a hot climate and lost 4 bars already on his '15. I bet there are those with '15s in the mild Pacific NW who are still at all 12 bars with well above 30K miles.
You can see at viewtopic.php?p=520738#p520738 a pointer to a guy in the PNW who lost his first bar on a '13 (lizard battery didn't exist yet) in July 2017 at 92.7K miles. You can also see my info vs. a guy in Phoenix with the same build month as me. My 5/2013 built Leaf at 63K miles in a hotter part of the SF Bay Area still has 11 bars and SOH is fluctuating between 82.xx and 84.xx% now.
There is no known published "expected" bar loss rate. Nissan I'm sure has some data but hasn't provided any. And, as I said, depends on the above factors and we can only guess based upon notes that we have. And, it also depends on the revision/version of battery.
