What kind of battery life? with slingplayer?

I know it's a brand new app, and probably you guys haven't tried this, but how is the battery drainage with slingplayer? I mean will most of my battery disappear with watching it for couple hours? I would assume it's pretty bad since it's doing constant downloading with data...

just wanted to know. I'm a passenger in a truck for 10 hours a day at work, and would be nice to get some tv while just sitting around lol

 

I posted this in another thread, but I ran it for an hour on wifi and it drained my phone by 30% (I had other apps running in the background, buut nothing out of the ordinary or intensive). I'd guess you can probably get 2 1/2 to 3 hours on a full charge, otherwise why not plug it into your car or laptop?
