I don’t think I am going to take confident proclamations about how it works from someone who thinks “voltage” translates to “how much energy is left in the battery”.
I don’t really know how this stuff works, that’s why it is my conspiracy theory instead of me just giving fun facts. But, I don’t think you know how this stuff works either.
It sounds like coulomb counting (current sensors, as you said) is often the method. Personally, I suspect there’s a decent amount of bullshit inserted into that to make it look “normal” when people are looking at how the number behaves, at the expense of accuracy. You might move your phone from cold to warm for example, and the usable energy in the battery might increase when that happens (or something) but it’s definitely not going to show your battery percent going up, even if it could detect it properly which I don’t think it can. Whether to say that means it’s “bullshit” is I guess a matter of opinion.
Phones don’t use lead acid batteries, genius. I don’t know why you think that study is relevant.
Also, your phone knows what the temperature of the battery is, and almost certainly takes that into account, although this affects the output voltage but not the amount of energy stored.
Li-ion is worse. I looked up a few different articles, I just kind of picked that one at random because I didn’t want to spend more time on it. This one is pretty succinct about it:
“This method is not suitable for some other cell chemistries like lithium-ion, which has a negligible change in its voltage throughout most of its charge/discharge cycle.”
My new conspiracy theory is that a gang of people have teamed up to try to wind me up on this particular topic in what was supposed to be a lighthearted nonsense-question to which I gave an appropriate nonsense-answer.
You’re the only one who actually did arrive at something which is pretty much the actual answer (“coulomb counting”), although you keep mucking it up by saying things like you “can get a voltage sensor” to get the energy left in the battery, or “current through the battery” when the battery is the only part current does not flow through during discharge, or by making up wild random guesses that something is “almost certainly” taken into account. Just take all that extra stuff away and stick with “the phone monitors discharge” and you’ll be pretty much right.
Hopefully we can put this whole endeavor behind us now, and go back to talking about Chipotle and chemtrails.

“This method is not suitable for some other cell chemistries like lithium-ion, which has a negligible change in its voltage throughout most of its charge/discharge cycle.”
Which is why the phone also monitors charge and discharge, or current through the battery.

It’s very clear from this exchange that you don’t know dick about electronics.
The evidence for my secondary conspiracy theory grows stronger
