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. Thread reply - more options

If you have an iPhone, however, you can set up a handy shortcut that will turn on a red filter, which is much more gentle on the eyes and helps preserve dark-adapted vision.

FujiiWhen you first turn off your bedroom light or step outside on a dark winter's night, you'll notice you can barely see anything. But after about 30 minutes you'll be able to see objects much more clearly. This is because your eyes acclimatise to darkness over time. Returning to a light-filled room, shining a white torch or looking at a bright smartphone screen can ruin your dark-adapted vision, meaning you will have to wait for your eyes to re-adapt to the darkness.

Step outside one clear, dark night and look up at the stars. Now wait 30 minutes and look again. You should be able to see many more stars than you could at first. If you're observing in a dark location and need to see where you are going or choose a different eyepiece, read a star-chart, reference book or consult a planisphere, a red light torch will help preserve your night vision.
