Why are batteries in phones always measured in mAh instead of Wh like for example notebooks?

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. 🚗
