I run TG Pro to monitor my processor temps, mainly to alert me to processes that are consuming too much CPU. One thing that I've noticed so far with the Air M5 vs the Air M4 is that the processors are running cooler. My displayed "Highest" and "Average" temps are generally about 10-15 degrees F cooler. I would have to imagine that's helping with battery life even though the M5 isn't rated for longer battery life. I thought that was interesting and figured I'd pass it along.
