Here you go : webbrowsing 16.5 hours without fan.. Video playback 25.14h.. 156h runtime.. of an Galaxy M51.. Much more power efficient than a macbook for basic computing needs. all on battery fanless with a very small battery.

The phone as close to M1 MAx singel core performance (1500 vs 1700 geekbench, look it up).. Battery is only 12.3 Wh on the samsung, a macbook pro has... 5 times as big battery (70Wh). so yes.. it is obivous that the Note 7 is more energy efficient. thatn the Mac. just look at the references and do the calculus.
I looked up the first two of those phones and they're offbrand chunky bois (literally thicker than the thickest part of a MacBook Air) with batteries in the same size class as a MacBook Air (about 50 Wh). I doubt many people are buying these, but whatever.
Apple rates the MBA for about 15 hours web browsing, 18 hours video playback. So if you're a deliberately obtuse
@Leifi, you might try to treat this as if it's a result which proves your point.
But complaining that a laptop has worse video playback time than a phone is silly. Both have SoCs which handle all the computation required for video playback in a dedicated video decompression block which needs only a few milliwatts. For both, the main drain on the battery during video playback is the display.
And guess what? Display power is proportional to screen area. You simply cannot expect a laptop with ~4x the display area to light up to have the same battery life as a phone with roughly the same battery capacity. Not unless you expect the physically impossible, that is.
