I would say on average, 3 to 4 hour's a day.
I charge my Note 2 before I go to bed. When I wake up my battery is at about 92% give or take a couple percent.
I check my email, texts, ect. Then it's all very light use during the day. Once I'm home I check my Pulse feeds, TapaTalk PM's or forums in subscribed to. I check out Google+ for a while. Then maybe surf the net.
On a day off, I'll be on my Note 2 either much more taking pictures or video if I'm out. Maybe send some texts and make a call. Or I'll chill at home and play a game for a while.. I'm on Wifi at home so I'll get about 20 hours of light to medium use, a total of about 5 hours of display time.
My Note 2 hardly ever sits for two days rarely used.
I'm always using Google Now, checking for events nearby. I'm pretty much always on my Note 2 when I'm not on my PC. If I'm not working or out with friends. And as I said when I'm out with friend's. I take some pictures or video's.
I run my Note 2 hard. It's great because my friends and family have Samsung devices as well so S-Beam can really come in handy.
