> they're reducing the peak demand on the batteries to avoid spontaneous shutdown when the aged battery can't handle the load.

It doesn't seem to help my gf had an iPhone 5 that started dying on peak demand but only after it got upgraded to new ios (i guess 8.0).

We replaced it (it had bad battery from the start and apple had a program for replacing those). After few years on new battery it started doing the same thing again. I replaced the battery and it stopped. But I know what I can expect in two years or so. Maybe I should stock on iPhone 5 batteries? Do they age less if they are unused?

All batteries wear out after a few years of use.

I understand lasting shorter on charge but shutting down when I turn on the camera while on 40% is uniquely apple experience.

I've seen the same shutdown problem on multiple different Android devices with degraded batteries.

I must have been lucky then.

nope.
