Dropped my iPhone in water. Can I still charge it?

So I recently dropped my IPhone in the toilet, right after it happened I immediately took it out & played with it to see if it would work. I texted my boyfriend after the incident, & he told me to out into rice, on airplane mode, & leave it over night. But there's only one problem. My phones at 10%, & I need it charged for tomorrow. Can I charge it, or is it a bad idea? By the way, after I pulled my phone out of the toilet, I plugged it in to see if the charger still worked, & it was fine. I just need to know if I can still charge it or not.

I'm new to mac. I'm getting used to everything. I looked in my storage & it says that i have 11 gb's of music when i only have 7 on my iPhone. I have a music folder in my documents section filled with all of the music that is on my iPhone & it's around 7 gbs added up. Thoughts?

IPhone 5 screen blacked out?

So I was on my phone about two days ago when my iPhone 5 just blacked out. The only thing you could hear was Siri when you held the home button down. The problem is my power button stopped working a long time ago so resetting my phone won't help. And I don't have access to a computer either. How can I fix this issue?

Should I update the software on my iPhone 5S?

I don't know if I should. All I'm scared about is my videos or pictures not being able to be seen or heard from my phone. Or worse, deleted. The pics/vids are stored on my laptop. But still, I'd like to have it on my phone. If I choose to update, it's going to be iOS 7.1.2. Should I? Will it delete or mute videos and pictures?
