Have burners if you want, but realize that with vanilla Android or Apple iOS on those devices, they will suck up a lot of data about surrounding devices, Bluetooth devices, and wifi networks. This can be probabalistically matched to your real identity even if you use VPNs and you aren’t using any known accounts on the burners. As for GPS data, that’s even worse.
Its probably best to have at least one “normie” phone you do boring stuff on, a Graphene enabled phone for sensitive-but-not-illegal daily driving, and anything spicier than that should be a burner in a Faraday bag, which you cycle and destroy/discard regularly.
GrapheneOS is about as close as you will get.
