I can’t help you understand what is true. “All day battery is true for 12 months for the average user. It degrades from there.That comment makes no sense. How does Apple building to “all day performance" year after year have anything to do with upgrading? Having all day performance means most buyers simply do not think about battery as an issue. Why would "you have more battery capacity you won’t upgrade as often?"
Most people upgrade every 3-4 years. Most people upgrade due to poor battery performance. If Apple gives you 2-3 capacity out of the box, the upgrade cycle will extend. It’s really simple. Really, really simple.
