> what answer you’re looking for here
It was a rhetorical question, yet a Jobs' fanboi couldn't resist, see the neighbouring comment.
> each system is different
Except in that part it's pretty much the same. Or your battery, even discharged, can keep up with a full load from a CPU, GPU, WiFi and GPS modules eating amps, or it couldn't even when it's fresh.
If at 3V your battery couldn't power the system then you shouldn't show 3V as 30%, you should show it as 0% and adjust %/V curve accordingly.
It's simple, it's about momentary load in amps, but "only some iPhone 6S models manufactured in September and October 2015 had suffered from a battery manufacturing defect" yet millions of iPhones were slowed down ~~totally not beacuse Apple needed to sell the next iPhone~~.
And as an anecdote - even after the years of abuse, the last time I used my XT910 it was literally showing 10% when I enabled the radio so I could receive a SMS from my bank on it. I really expected it to just shutdown (because enabling radio means data too, so all that bullshit rushed to update their things and using data => more power draw) and for me to be stranded in a remote city without money. But not only it did survive that, it kept chugging for another 4 hours, with radio disabled, ofc. *shrug_emoji*
> Or what is your point?
What people would eagerly drink any Koolaid what would make them feel entitled or standing out. Which most Apple fanbois vehemently deny.
NB: there are people who just use iPhones/Macs/whatever and don't engage in defending 'their favourite brand', of course they aren't fanbois.
