Among the many changes, the new rules would require batteries in consumer devices like smartphones to be easily removable and replaceable. That's far from the case today...
Keeping your Li-Ion battery in the “goldilocks zone” (20-80%) does have an impact on the wear. Usually it’s charging the top 10-20% of the battery which has the most impact. I replaced my last battery after 4 years, at which point it had an estimated ~70% capacity remaining.
I think you’re overestimating how much that helps and underestimating how good/smart batteries and charging has got. 80% after 800 cycles is the current industry standard with some now pushing that to 1600 cycles.
I’m currently at 95% health with the phone being 3 months shy of 2 years old, no care taken just charging with a fast charger when needed. At the current rate/trend for me that’s another 4 years to end up at 70% health so 6 years total.
