After my first day at work. Keeping in mind that my office is a black hole of signal, this is awesome. My GS3 lasted about 3 hours unless I put it in airplane mode. To be able to keep my phone on is amazing. Judging by what's left, I'll be able to carry through, even if I go out after work and forget to use my car charger, or charge any at work. (Yes, I know screen on is small, but I'm working at work, so that's no biggie for me.)
Edit: I did leave wifi (no connection at work though) and bluetooth on, auto brightness.
Based on some of the other results I've been seeing, I'm wondering if you could do even better than this. Android OS is using a pretty high percentage of your battery, it seems. You may want to see if it's doing something odd. That's still a pretty big battery plunge for 13 hours. With that little usage, I'd think you'd still be well above 50%.
