They really can't make Exynos chips work huh. This effort is probably useless because the biggest issue in having an inneficient chip is not the heat, its that it will eat through the battery much faster than it should. I had a phone with a snapdragon 888 (manufactured by samsung foundry) and the thing barely lasted 3h30-4h on a full charge. After 2 years I got fed up and got an S23, with a smaller battery than my Zenfone 8 and I got basically more than double the battery life (8h-9h of screen on time with the same usage). Better cooling wont solve this. The heat is tolerable because unless the user is playing an intensive game, the phone is never truly hot, its just warmer than it should be for rendering a website.
