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.
