I could see the benefit on a non-phone mobile device. Completely cutting power as a deep sleep without needing a lengthy boot sequence could be nice.
Unless it’s actually “just as fast” as volatile memory (including progress to the latter) and not more expensive, though, it seems like it wouldn’t justify the tradeoffs.
pRAM can actually be faster than DRAM in terms of latency. Main problems are cost, density and power consumption (to varying degrees, depending on the concrete technology)

This is where micron and Intel tried the phase change memory, optane, they could never make it cheap and fast enough to direct replace.
