I can't speak about the Exynos, but Yesterday I was on the phone for an hour and I only went down about 6%. That's a marked improvement over my SGSII running CM9

I think you need to wait a week before making judgement calls like this.

#1 - From all of the screenshots I've seen, it's cellular standby which is chewing the most power. I'm sure someone will get to the bottom of this.
#2 - These phones are all probably on their first battery cycle. I know mine was. In a week, we should have a better idea of what's going on.

There really isn't a science to the "Battery Cycle" or breakin period. Really it's "New Device Syndrome," you have a new device, you use it more than you normally would. Turning the screen on to check something, everything. As you get used to the device you settle into your normal usage pattern (not a device usage pattern) and you get your optimal battery life.

I'd say the battery is pretty decent. Of course if you run the camera or cpu intensive apps and light up the screen on max, it'll drain faster. Yesterday after a full charge and a full day at work I had about 60% (8 AM to 6PM). Keep in mind that I just got the phone and kept turning it on aimlessly to look for apps and play around with different social apps and the browser.

There is no doubt that's a large portion of the change/difference in battery life, but with most battery technology (lithium ion, lithium polymer, etc) there is something to be gained from completing a learning cycle or two to get realistic discharge/charge boundries, so that your percentage accurately reflects the actual battery state.

Here's today's battery capture. I've disabled power saving for cpu/gpu, the other two options are on, screen is set to auto. I used the screen about an hour today, but drove ~2 hours with Slacker Radio playing and streaming via BT. GPS is on, BT is on, WiFi is on. There's about 4 hours of not being in WiFi coverage reflected by this.

I did a 2.5 hour trip with wifi (there's a lot of wifi from my cable company around here), blue tooth connected playing music, SVoice to control the phone, and Google gps navigation running, 20% of the battery, I didn't have the screen on all the time.

Looks like the cell standby bug is present on the AT&T version. That sucks. Cell standby should generally take up less than 10% battery. See attached.

Are you in an LTE area? I have LTE everywhere I go. Just because you don't have an issue with your phone doesn't mean there isn't a problem that affects others. I'm not intentionally making cellular standby 30% of my usage (or more), I assure you. If you're not in an LTE area, maybe that accounts for it - if you are in an LTE area, then something is odd.
