On smartphones, is there a difference between waterproof and water-resistant?

Well... it depends. Casual language versus technical standards talk.
Some people argue "water-resistant" is more like "splash-proof" - i.e. a quick accidental dunk in the sink or a heavy shower won't kill your device while a swim with it cross-channel is out of the question.

The technical standard used, afaik, is referring to Ingress Protection (thus the IP-rating...).
A dude over on Livemint explains it here

Cheers, I've actually learnt something today. I was never sure how IP ratings worked, now I know.

Basically, you can leave your S5 in the dust behind your sofa all week, but you can only leave it in the bath for half an hour (side note: I wonder how soap/shampoo would impact on the nano-coating?).

Exactly. Solvents, soaps, combined with heat from bath water or a running shower?
Or, leave the device in a hot car, then on your beach towel in the sun... sizzle. And whooosh, you take it into the ocean. A 30 degree temperature difference. Plus salt. I don't think this is for 'life'.

Exactly. It offers protection if you, for example, drop your phone in the toilet or in the washing up bowl, but it's nothing more than accidental immersion protection, in reality.

If you want a waterproof phone, you need one of those JCB phones, or something similar.
