wifi is killing my battery

[MarisaMcAwesome]

I just got my nexus 7 for Christmas and so far I've noticed the battery life is awesome. Well today I downloaded frostwire and my battery was at like 50%. I wanted to download a song but didnt have time to make sure it downloaded correctly. A couple hours later I came back to my tablet and the battery was down to 16% and the WiFi icon at the top was indicating that it was using internet. I thought that was weird because nothing was downloading and I had only seen that icon if I was updating Facebook or something. Now its been about 5 hours and its still `downloading' something even though I've closed every app and even deleted frostwire. Is there any way to see what its trying to do and stop whatever that is??

Settings > Apps > Running. Look through the list. Also, Settings > Battery, see what is using your battery.

it says nothing is using it, but the little wifi icon on my statusbar says that it's receiving data, and i have NO idea what it's receiving. i also just tried resetting my tablet and it's still got the same problem. Whatever it's 'receiving' is completely draining my battery if my wifi is on.
