Slow-mo camera FPS drop in iphone pro models

FPS rate of slow mo camera in iPhone 14 pro drops gradually and reaches to 185 fps from 240 fps until the next restart.

Initially after restart if you will record video and check description of recorded video it will be around 240 fps but with time like around a week without restart of iphone if you will again record slowmo video and check its fps it will drop around 180 fps with the 240 fps slow mo recording mode.

I complained about it on apple support but they don’t consider it as a problem. They assume it as normal behaviour of camera due to varying light and brightness, even when i shown them before & after fps drop of recorded video with same high brightness recorded video they were not ready to accept.

I read a-lot of blogs and every one with pro model of iphones are facing the same problem but still apple doesn’t care.

I don’t know why apple is ignoring this issue.

Do anyone have any solution?
