Good to see you Trophy, and really glad you're enjoying your 5
I really don't understand what the issue was with the Gnex. I got one for my Father-in-law, it's on Sprint, and he doesn't have any issues. I rooted and rom'd it the instant I got it home, but still seems strange. Maybe it's the newer JB kernel, IDK?
The LTEvo gets 20-30 hours for me regularly, but I don't pound it either.
In the end what works for you is what's best my man. Also remember:
Don't be a stranger my man.
