Is there a problem with Apple's mobile phone camera taking pictures for an hour?

Apple's mobile phone camera has problems taking pictures for an hour. IPhone 13pm time-lapse photography takes about an hour, but time-lapse photography consumes a lot of power. During the first 10 minute of iPhone's delayed shooting, two images are recorded every second, but if the recording time exceeds 10 minute, the frame rate will be doubled to record one image every second, and the original redundant images will be deleted.
