iPhone 12 Pro Max constant blinking red light

I just want to know if this is normal. I can see a red light on the left side of the notch blinking all the time, I notice it more so in the dark. Is that normal to constantly be doing that? I also feel like my battery is draining a lot faster than my iPhone 11 Pro Max did! Thanks for the help.

iPhone 12 Pro Max, iOS 14

You are rare in that you can evidently see IR light. Most humans cannot see it, but yes, it is normal for it to blink. I can't see it. No one I know can see it.


The IR sensor however is very low energy and would not be cause for a battery drain faster. The IR light is constantly on. It is what your phone uses for Face ID.
