The below requirements for IP ratings are very loosey goosey
I mean, even their weasel words imply that the device should continue to operate...at some point...
"In general, if any water has entered, it shall not be sufficient to interfere with the correct operation of the equipment or impair safety"
The weasel is they say the charge ports etc are 'drain holes' and once the device 'drains' the device should be fine. Except the 'draining' in my case took a week...in silica gel because you essentially have to wait for it to evaporate as the unit is practically sealed...just not sealed enough to stop the water getting IN...
Meanwhile, my Fujifilm XP90 camera, apparently slightly lower IPX8 rated, has successfully filmed underwater, in lazy rivers, for multiple years, with not a single issue, and never had to get with the silica gel.
YMMV
Yeah...but I'd advise NOT going for a dip with that new $1500 phone....
