Mobile devices are used in a bursty fashion, if you want to run an SoC flat out for five minutes you're not really using it as intended. If you want to use your iPhone for multiple hour calculations, toss it in a quart of icewater and stick it in the fridge...make use of that IP68 rating :)

You still have to "pay" for that heat when the phase changes back and it gets really hot, so the better it works at absorbing heat the worse off you are for prolonged use beyond that point. Plus it costs weight and volume, which is precious in mobile devices.
