The thing is, batteries are measured in Ah, and not Wh. That’s because their voltage changes all the time, and is mostly the same for the same kind of chemistry, and also because for most of their uses, the current is the actually useful information.
Phones are just using the standard metric. It’s laptops that are weird.
They both tell the same story, but one requires extra information you don’t have. You don’t say that the latest i3 pulls 6 Amps, you say it pulls 65 Watts. Also the voltage does change as the battery discharges, that’s why you use the nominal voltage of the pack. mAh is also not a current

We aren’t using joules because…?
At least we’re not talking about cars because…
I wouldn’t be able to stop. 🚗
