Why is my iphone 5 dying so fast

When i first got the iphone 5 2 weeks ago, it took a long time for it to die. It would last about 2 days. When i charge it i wait for it to die completely before plugging it in. Now it can't even last a full day… What is wrong with my phone? After i plug it in it will only last about 4 hours. I'm really upset because it used to last 2 days and now it won't last longer then 4 hours. WHAT's WRONG!

Food Damage on iphone 5 speaker?

So basically i accidentally got icing on the speaker at the bottom of my iphone 5. I got all the icing out and used this method i found on google which was use peroxide and water to remove it on the inside, however right after i got the icing out and before i did the peroxide and water thing the speaker was really faint and distorted, i can still hear however, its extremely faint. Is there a way to fix this? It works fine with the headphones plugged in but when someone calls me or i misplace my phone i won't be able to hear it. I really don't wanna pay 600 bucks for a replacement. Is there a way I can fix this problem at home? Also i'm only 16 so i don't know much about how to fix this help please.
