About a week ago, I dropped my iPod touch into a puddle of water accidentally. I let it be for about 2 days, and when I came back, it was working. But I've noticed that the battery life has dropped significantly (maybe 1.5 hours). Is there anything I can do besides changing my settings, or is there a place that I can buy a new battery? Also, my wi-fi no longer works. When I go to settings, it's a gray icon, and it can no longer be pressed, and it says No Wi-Fi. Is there any way to fix these? Thank you.
