any S3 user carry second battery like me?

I don't know whether I am the only one need to recharge the S3 battery everyday. It is a great phone since I have got it couple of months and it still runs pretty smooth, but when I use data on my it heavily---webs, FB,texting,youtube and other streaming videos, and some games, power darins fast surprisingly. I think most of smartphones today are about same battery issue. For me, extra batteries are my must have phone stuff…my current one(6000mah) got from mpj at a decent price weeks ago works good.without need for recharge everyday.

No else around me owns S3, so I wander if other user also carry a second one?
