iPhone 15 Pro Poor Battery Performance

I have had my iPhone 15 Pro for 7 months now. I am only able to achieve between 5-6 hours of active screen time despite all my efforts to use the device conservatively. This has been a consistent issue. I was able to achieve a longer active screen time on my iPhone 13 (not even the pro version) using the device in the same manner. I have paid significantly more to upgrade and get a worse battery life. I have turned off my always on display and mostly operate on the lowest screen brightness settings. My current battery health is at 92% which is deemed as normal. How is 5 hours of active screen time per 100% battery charge normal ???? (with almost every app background processing disabled)
