[Battery] My battery dies quickly.

I'm just saying pre-GDR2 I could leave my G3 on and it lasted for a lot more than 12-16 hours.

I am pretty sure it turned off automatically whenever Wifi was available thus saving a lot of battery when at work or at home.
With this behaviour in GDR2 toggles are a must. It's a drag to micromanage your connections through the settings page.

With all that said, it's still the best phone I've had, let's hope they patch a few things with GDR3 and add tons of cool features with 8.1

Lets hope together!
