That's weird. My xqbc62-v notification LED is dim and has a narrow viewing angle. I can only see it at night.
I think there are multiple hardware revisions of this phone. My first phone was purple and crashed constantly. I returned it and bought a new one later. It's purple, but so dark that it looks back except under direct sun.
I see what you mean now. The BC62 notification LED used to track ambient light and it was always relatively dim. Starting with the Android 12 update, it's max brightness all the time. It's annoying at night.
What I have found to work is completely unscientific but works every time for me. I use a cable so not sure if it will do the same for wireless. After I plug it in I too notice that the LED is too bright. So I wait a minute or more and unlock the phone with my fingerprint (while the charging cable is still plugged in) and then double tap the screen to relock the phone. I use Nova Prime as my launcher which allows me to double tap to lock. Usually doing this makes the LED dim down considerably. Sometimes I have to do it 2 or 3 times but it always ends up working. YMMV
