While the other comments are correct to point out that majority of mobile workloads are rush to completion, many users (especially in China) still do a lot of heavy gaming on their phones. This is exactly why the newer SoCs are so interesting- that they can deliver more performance for the same power consumption. (Directly increasing run time and decreasing heating)

I think most children prefer to play on phones these days. Mobile gaming is huge. To the point where game loops on high-end games are optimized around thermal throttling.
