I'd also like to mention that this guy's situation isn't really related to his phone. He was on trail (albeit the wrong trail) and sounds like he was panicking due to dehydration (he tried drinking his piss) meanwhile he's right beside a creek. If you're doing 18 mile hikes, bring a water filter or some other water treatment method. If you happen to find yourself in a situation without water treatment, drinking directly from a stream is usually a far better option than drinking your piss or risking dehydration. Yes, there's the risk of microbial diseases but those will generally take a while to kick in and you can hopefully get back to your car by then and go to the doctor if that happens.
