iPhone 7 survives two day 30-foot submergence, text at depth alerts diver

iPhone 7 survives two day 30-foot submergence, text at depth alerts diver
I just don't see how it's possible that the iPhone could pick up a usable cellular signal at 30 below the surface in sea water. The signal attenuation at high frequencies like GSM in salt water is significant. For the phone to talk back to the tower would require a lot more power than the battery life indicated. I suspect that the notification was from something other than a recent message.
This highly technical paper agrees with what I know (and I'm a EE):

Researchers find loophole that extends USB Restricted Mode's hour-long timer

Leaving a device for more than an hour and then plugging it in does not activate charging. This is an all-Apple environment. iPhone 6 plugged into a 27” Cinema Display with an Apple Lighting cable, plugged into a 2009 Mac Pro. Only after it’s unlocked does the charging *ping* sound and the battery icon turn green. -

Do these benchmarks generally get submitted by accident, or are they purposely seeded for some marketing reason? -
Microsoft's next Surface product might be just pocket-sized
