IMO bot that important practically - SiC batteries, active cooling, bypass charging etc - if one really cares about sustained performance (gaming etc), PRC has phones segments big on mitigating thermal throttling. Exclude benchmark drama, golden samples, retail units still vastly outperform passively cooled phones with "better" silicon on long sessions. Otherwise there aren't many usage case where power consumption matters between that can't be trivially made up by slightly better or larger battery and/or passive cooling.
