I don't dispute that, but that does not explain the observations that a fully-charged, reduced-capacity battery performs poorly on a standard benchmark test versus a new battery.

It's not just smoothing out a peak demand. It's reducing the peak performance all of the time, and that is unique to iPhone.

You're assuming the issue is only changing capacity vs age. Internal impedance increases with age as well. A full battery that can't source its energy in a timely manner might as well be empty.

That's not entirely accurate. They observed that with a fully charged battery it performed as expected. The CPU wasn't throttled until the battery was depleted.

That's not my experience. Unless depleted means 95% charged and 87% capacity compared to original spec.

Mine runs at 50% CPU speed under those circumstances. I wouldn't call that "performing as expected."
