Hey just got my battery yesterday and am going to see how well it holds up I am a heavy user. Stock I only got about 3hrs out of original battery! Lets see how it goes!!
I think you'll like it. On days that I'm a heavy user I get about 8-10.
"Heavy Use" to me is the following:
Playing games
Phone calls
Texting
Emails
XDA
Wifi on all day
Brightness all the way up
4G on all day
