Google has had offline maps for years now. I always keep my local area updated, and whenever I go to a new place a download the map for it first. I've had out of date directions on my phone, but I've haven't had an issue with out of signal since offline maps became a thing. I do not recall ever having drained my cell battery completely. And I have a car charger. There are reasons to keep paper maps around, but lack of signal and running out of battery aren't on the list.
