iPhone 6 (Plus) was when it was realized that people care a lot about the camera. Folks bought iPhone 6 Plus phones they didn’t want for stabilization.
Apple prioritized camera over thickness at that point. Battery is lower on the list and is mostly addressed by CPU improvements.
IMO it’s frustrating that they are so conservative with a mature product. We waited over a decade for basic waterproofing. Apple has an incredible supply chain, but Samsung can deliver better/more diverse form factors. Example: ruggedish phones.
Apple’s focus is both amazing and frustrating to me. They had and lost an opportunity to break Microsoft clients in business.
