iPhone camera quality does not worsen over time; the camera sensor improves. All sensors become more sensitive and produce higher-quality images over time.  Some people might think that time will affect a camera's image quality, but it doesn't. An iPhone camera's quality does not depend on the amount of time used. Cameras are the same, regardless of whether they are five years old or fifty years old. However, some factors can damage a camera. These factors can include the lens, the sensor, or the glass protector. If any of these parts are damaged, the camera will begin to show its flaws.
