Taking those scores on GSMArena at face value is bullshit (if anyone is wondering, that's 86h and 126h on their 'endurance rating').

The S23 Ultra only gets 126h 'endurance' because it can do 40 hours of phone calls, a lot more than the iPhone. How many phone calls do you make? It has worse battery life for things you actually do on a phone.

From their data, S23 5000mah vs iPhone 15 3300mah:

- games: 8h44m vs 8h16m

- video playback: 15h47m x 18h20m

- web browsing: 10h51m x 11h43m

Comparing against the iPhone 15 Max (still a smaller battery at 4400mah) it's a lot worse.

Max is better, but non-Max is bad. Call duration metric is actually good and useful. For example new Pixel 8 and 8 Pro have crap call score. What does it mean in real life - some people say that their pixel 8 has ok autonomy but after some investigation they admit that they use it at home/work on wifi. And then people using it on a cell network, especially in the bad reception zone, report atrocious life time, due to bad modem or something in that area. So it is important metric too.

Basically optimizations of the iphones can compensate maybe a few hundreds of mAh, but not 2000, that's not possible.
