Most Cellphones are using at most 11W while under load, and will often throttle below that very quickly. While I couldn’t find exact numbers on power draw for the new Pi, the new power supply for the Pi5 is 27W. That’s a significant change in power consumption at these sizes, and would explain the recommendation for active cooling. I’ll also add that there are gaming phones that do use fans either built in or as add-ons, for active cooling for sustained loads. But that’s a niche use case/market.
