I’m a little over 2.5 yrs on a Sony Xperia 5 III, I use the 80% limit feature but not as good about keeping above 20%; and avoid fast chargers for overnight charges.
I don’t have hard accubattery numbers but still works fine, I end most days pretty low for last year probably but never with range anxiety. No need/desire to increase my limit to 90% or 100% for extra use time yet
It technically forbids insurance companies from denying coverage to people with pre-existing conditions, but clearly they just realized they can take our money then deny services instead.
Also it threw a bone to the insurance companies by fining anyone not covered by insurance - incentivising new customers to just pay for insurance instead.
So tbh it was indeed a flop imo
