One thing about phone battery cooling is that the outer surface area to volume ratio is much greater making it cool much better without the need for external cooling.

My iPhone XR has a 2.94 Ah battery. When it came out a Model 3 long range had a 230 Ah battery.

Amp-hours are kind of a funny way to compare a single cell pile to a multi-cell battery. Watt-hours would seem to be a better metric. Same thing with current vs power.
The 2.94Ah iPhone cell has a nominal voltage of around 3.6V. So that's almost 10.6Wh.
The Model 3 Long Range battery is around 79,000Wh, or 7,464 times bigger.
