I was with one of my ex's, at the hot-tub.
Spur of a moment thing. Jumped in still wearing my bermuda's and I had my old Samsung cell-phone in it.
Was in there about a half hour before I realized, oops, phone in pants. Needless to say it was the last thing on my mind and I didn't even notice it till I chucked the bermuda's onto the side and heard that nasty "clunk" of an expensive phone crying for help.
So, fast forward to a few hours later, I have the whole phone pulled apart at my place, except the screen and keypad, sitting under a light, drying. Left it there for a good bit.
A day and a half later, I tried it out, no dice. No juice.
A day after that I figured, hey, I have a spare battery, let me try that. Popped it in and the bloody thing WORKED
So, battery == dead. Phone == WINNAR !!! And I used it for almost a year afterwards with no ill-effects. It even kept all the data I had stored safe
