Is it? The article lists 2015 as the year where things improved a lot, 2017 is well past that. The numbers are low and even that's inflated due to recalls.

I've seen >>10 year old laptops where the battery is still good enough to go from charger to charger. Just go to ebay and check out 2009 MacBooks. That's ~15 years now.

I don't think this is unrealistic if you can live with the heavier degradation.
