Assuming your movements are tracked by other methods (surveillance cameras and facial recognition, purchase records, etc) the absence of your phone when you would otherwise normally have it is a data point, too.
There is no time that I would normally have my phone other than when I am at home; the data point that I provide would be the rare times I take my phone out of the house and most of that time it is off, I only turn it on if I actually need it. My phone is turned off a fair amount which also means I do not have internet since I get my internet through my phone's hotspot, it is nice to be able to disconnect from the world so simply, just turn off my phone. If this was the norm, location data would have far less value and possibly not be worth the expense. Phone addiction seems the real issue here.
My purchasing data is not much better, two purchases so far this year other than my three monthly bills and groceries once or twice a week where I also get cash for my other expenses. I don't do this out of concern about being tracked, just how I live my life. Sometimes I leave my phone off for a week, nothing bad happens, at least nothing that having my phone on would have prevented.
