is this good battery life for a laptop with ulv processor?

[Batman1121]

I have a Asus x555l laptop with i5 4210u processor so I was expecting battery life to be good but even on lowest brightness and power saving mode on, I get a little over 3 hrs of continuous web surfing(watching videos mostly).
When watching movies (without wifi on) i get 4.5-5hr.I don't game on battery but i expect it would last maybe an hour.
Are these numbers good enough?
The laptop uses 2Cells 37 Whrs Polymer Battery.Is this what is mostly used in such laptops?
Thanks

That's really good battery life for that laptop. My companies Dell laptops with the same processor average about 2.5 hours of surfing / meeting times.
