My iPhone 15 Pro Max now scores 200-300 lower points on Geekbench 6 on iOS 18 and 18.1 beta compared to iOS 17. Apple claims better battery life by adjusting CPU ramp up speed on iPhone 14 and 15 Pro models. But I believe that this is done specifically to show 16 models as better performers. Never seen an iPhone CPU getting a permanent nerf like this. My battery life has been as pathetic as it had been before on iOS 17. My phone battery health is still 98% with 150 cycles.
 
Apparently it's not quite a shameless move to make the 16 Pro look better. Geekerwan covered this.

iOS 18 increases the delay between when the iPhone needs more oomph and when the iPhone ramps up to full speed. It's an efficiency improvement and Geekerwan noticed their 15 Pro Max lasted about an hour longer in the battery test using iOS 18 vs iOS 17. The 15 Pros won't perform any worse overall in 99% of cases. The 1% of cases where it looks like it performs worse are in benchmarks... so what?

From what I've seen you should be celebrating. You get the same performance in almost all scenarios but with even longer battery life. Win win.
