Is my 12 volt dying? Or other range issue?

So one night my 90 percent range on my SR+ dropped from 205-207 miles to 198-200 and now it feels like my range is getting used up slightly faster than usual. I have seen that both of these can be symptoms of a dying 12 volt. My phone key has also been really intermittent, although I don't know that that is related as it seems to mainly happen on my iphone 12 minis and not the regular 12. Is this the 12 volt or am I having a different problem with my range here. Thanks.

Your Tesla is likely not deep sleeping. Can be sentry mod, cold weather. 12v battery is charged from main battery and can use 400wh. 12v charging is P1. This my main source of basic consumption on my SR+. Have your 12v checked at a local garage it takes 1min.
