My iphone 5s got wet. When would be a good time to plug into the charger?

So, i went to the beach with my brand new iphone 5s (just got almost 3 weeks ago) and it had a lifeproof case on it but somehow it didn't work and got water inside the case causing my iphone to get wet. It started glitching and colored lines appeared on the screen. I turned it off immediately and let it sit out in the sun all day while i was at the beach. As soon as i go home i put in rice and checked on it the next morning. It works totally fine but there's moisture damage behind the screen. I read something online to fix that but it requires plugging your iphone into the charger… I'm really scared to plug it in to the charger though because i know that it breaks the phone if its still wet. So do you think its still wet and i shouldnt plug it in or what? I don't know what to do.

Have you put it in a bag of dry (uncooked) rice overnight? That usually absorbs all the extra moisture.
