Another aspect of Apple processor updates is increased battery performance per unit of work.
Battery in SE 2 compared to 3 is 11% larger (1821 mAh to 2018 mAh) but advertised "video playback" duration is 15% larger (13 h to 15h). This is unlike the comparison of SE 1 to 2 in which an 18% larger battery (1624 mAh to 1821 mAh) was entirely eaten by screen, etc. for no improved playback duration.
