iPhone’s Sensors

iPhone’s Advanced Sensors:

iPhone employs advanced built-in sensors—an accelerometer, a proximity sensor and an ambient light sensor—that automatically enhance the user experience and extend battery life. iPhone’s built-in accelerometer detects when the user has rotated the device from portrait to landscape, then automatically changes the contents of the display accordingly, with users immediately seeing the entire width of a web page, or a photo in its proper landscape aspect ratio.

iPhone’s built-in proximity sensor detects when you lift iPhone to your ear and immediately turns off the display to save power and prevent inadvertent touches until iPhone is moved away. iPhone’s built-in ambient light sensor automatically adjusts the display’s brightness to the appropriate level for the current ambient light, thereby enhancing the user experience and saving power at the same time.

I know the response is a little late, but the answer is easy… When it's dark you need less light to make the screen properly visible and the lighter it is, the more licht the display needs to keep it properly visible

theres a setting called auto lock where it automaticaly turns off after the time you select. Its on 2 minutes by default. Go to settings then general and then auto lock and select the time you want.
