Can an iPhone 12 Pro possibly survive in 5m / 16ft deep lake-water for 24 hours?

So yesterday night I dropped my new phone in a lake... We couldn't go after it at the time because it was too deep and too dark. I want to hire a diver if there is any chance that my phone is still working by now, but it's hard for me to figure out how (un)likely that actually is. I know the specifications say 30 Minutes in 2m deep water but I can imagine that the actual ability of the phone to stay underwater could be much better in some cases.
