iPhone 16 Pro Max
The camera is the most energy-demanding app you have on your iPhone. The CMOS sensors use huge amounts of power, and your 16PM has 3 of them.
Low power mode does not affect the camera, or even any apps you are actually using; what it does is postpone normal processing that would otherwise happen behind the scenes, and change other settings such as making Auto-Lock 30 seconds, regardless of your choice of setting.
