AT&T vs VZW Battery Life

i dont have the viphone yet. but I remember with my att iphone, after about a week the battery life improved drastically.
The verizon is so new, I would think the battery is not even broken in yet. I would give it a while for it to equalize before comparing. Also take into account how old the ATT battery is; it could have lost some of its charge capacity depending on its age.
I've owned many of the similar AT&T and Verizon phones in the past, RAZRs, Blackberry's and now the iPhone - in each instance, the AT&T phones or GSM phones for that matter always have better battery life. This is a known trade-off if you're going to CDMA, better network but requires more umph.
I second that. It took at least a good week before I started seeing more reliable battery levels and maximum usage time on my iPhone 4 on AT&T. Run it down and fully recharge it a couple times and take it from there.
I would like to know as well-also agree with those who say to wait a week til the battery is used a bit before comparing.
so far my VZ phone holds a charge better, but it is a little newer than my current ATT phone by probably 4 months....
Other variables include signal strength in your local area. One phone may work harder then another. How much data are you using initially. How old is your ATT iPhone vs. the new VZW iphone. Batteries perform differently as they age.
I think if the OP received a large population to his poll then perhaps some of those variables would shake out, and he can produce a mean on which we can see who's battery performs better but given the limit availability of the VZW iPhone and given that it was only available to current VZW customers shrink the available pool.
They're the same but its possible one technology (cdma vs. gsm) may be more effecient. I suspect that if there is any difference its negligible though. Any differences noticed can be explained by other factors as I noted in my earlier post.
Depends on whether you're talking 2G or 3G.
GSM added a CDMA radio type for 3G.
Moreover, it's Wideband CDMA, meaning it can pass more data, meaning it uses a higher clock rate, which in theory means it should use more battery than EVDO.

I purposely kept my AT&T iPhone 4 online and activated when I ordered my Verizon iPhone 4, just so that I could compare them and keep the best one.
I heavily rely on my iPhone throughout the day since I travel so much. Already being a customer of both carriers it's been easy to make this happen.
I find that the nature of a GSM phone (just as I had read about) is that they draw less current when not being used for data. Thus the advantage of GSM.
So far in the few days that I've had my Verizon iPhone along with my AT&T phone on the road with me, the difference is more than I anticipated. My AT&T phone (which is actually the one I was hoping to get rid of) gets about 40% longer battery life.
Yet the Verizon phone has the better antenna.
However since I've never had any issues with AT&T's phone service with my previous BlackBerry's or Samsung Blackjacks, the dropped call issues do seem to be the iPhone not AT&T's network.
And I'm not defending AT&T, frankly I don't give a rip about any carrier. Verizon is just as bad from a standpoint of cost.
So in the end, I'm still testing but it's not looking good in favor of the Verizon phone.
Understandable of course, but the mAh is the same. I cannot believe that the difference due to network technology is going to be so noticeable that it warrants this doomsday thread.
I've been playing around a lot with mine. 
And... my office is in Château d'If! I've always had crappy battery life on my phones down here. I never been with AT&T that I could compare but the d'If would likely not even permit a call.
A little less "Cut the Rope" and a little more work and I think I'll extend my battery just fine.

Let the battery condition for a week or two. The battery will need time to stabilize its charge life and for the phone to calibrate the battery meter correctly.
CMDA phones do tend to use a bit more battery power than GSM equivalents, but not that much more. Let the battery "mature" a bit, then compare. It's far too new to make a conclusion yet.
