But the problem is that the iPhones seems to last a day only when they are new-ish and there is no safety buffer down the road. If it is fine on release day it will not be fine after 2 years if there additional capacity build in.

Yes, that's a perfectly valid point - if they made it last 150% of a day on release they could ensure it lasts 100% of a day after two years without having to throttle the hardware.

I'm all for that - I do want all the power of the hardware and a full days charge, for the whole lifetime of the phone.

Unfortunately it's very much in the sellers interest to not do this. If they make it last 100% of a dayt on release they can instead make it cheaper/lighter/more powerful, AND if they throttle or make it behave worse some other way after 2 years, they also make it obsolete at just the right point in time.
