After dropping my iphone in the water the audio is messed up

So i dropped my iphone 4s in the water only the bottom part (speakers and usb port) for merely a second i towel dried it and blow dried the bottom as fast as i could the usb port is fine but the speakers are driving me crazy. Sometimes it won't play audio at all and when i try to change volume the volume thing won't display. But sometimes it works for 3 second then stops for 10 seconds then starts for a second again. Its like that for music, youtube videos, and texting. But when i go to settings the place you adjust the ringtone volume it works. Oh and its the same thing with headphones the audio stops and starts again. Please SAVE ME FROM THE MISERY OF LIVING WITHOUT MUSIC.

Iphone 5 battery won't charge?

About 2 weeks ago my iphone battery acted up. I use to plug it in, and instantly charges. From that day its gotten worse. I have to wiggle it to get it to charge, to holding it in very hardly to get it too charge. Too now holding it in hard for a couple of mintues till the phone gets the charge. And I have to set the phone in an upright positition "standing up" so there's force from the cord touching the floor to apply pressure to get it too charge? But after fighting for mintues to get to this point, I can go back within 10min and itll get the charge right away but only with pressure itll take it. After a few hours go by, its back to fighting until my iphone gets the connection again. What's up? I can't figure it out.

also. I have used a friends iphone charger cord and wall plug "that's brand new got his a week ago" to see if it was my cord and plug. His had the same effect, I still have to fight with it to get the charge. So its not my cord and plug, it has to be the phone. I have restarted several times to reset it. Moved charger locations. All to no aveil?
