You’re all primarily focusing on the battery.
I’ll always remember my iPhone 4. I’d recently had it replaced as the battery was lasting only a few hours. A while later, I updated to the new iOS back in 2014, and the phone became so frustratingly slow.
Every App was slow to load and the keyboard lag was unbearable. I moved to Android shortly after and never looked back. Apple definitely slowed down my phone so I’d need to upgrade!
I do have an iPad 9 now on iPad OS 17, and I haven’t noticed any battery issues or slowdowns compared with 15 and 16.
