Easily go 15 hours with 2 or 3 hours of online streaming, hour or so of social networking, same with you tube vids(HD stream), hour or so actually using the phone......to make a phone call. Imagine that! Also the galaxy s III, galaxy note 2 are also long lasting phones. Android has finally become a mature OS with 4.0(ICS) and it's only going to get better as phone manufactures get with the program with installing large batteries in their phones.
