My question is if this amounts to 1/6 the battery life.
I personally don't care for gfx intensive mobile games, i would rather OEM's focus on efficiency rather then raw power. But thats just my 2 cents.

There are some decent options for low power; the new A7 is basically a lower power/multicore A8 (found in SGS1 gen devices). But anything close to 1/6 is not happening, unless you get an E-ink display, possibly.
Obviously when it comes to battery life there are a million and one different factors, but considering a mobile devices usefulness is directly related to its ability to run(have battery) you would think this would be a more focused area. I mean i know most people are happy with a full days charge but i dont think it would be outlandish to say that the majority of phones limp in one 1 days use. Battery life has decreased over the years not increased.
My comment of "1/6 the battery usage" was more to if it has 6x the power does it use 6x the energy?
If you take the cutting edge gaming, then it would seem that you will get less playing time on the go with the tegra4 than the tegra3; there is no way that at full-tilt they use close to the same power.. but it can't be 6x either[2] But there seems to be a growing rift between the 'mobile' games and the cutting edge 3d ones.. perhaps we will see more 'low power/graphics' options available for OTG playing?
1. and we are really 'there' with chips like (quad core A15) tegra 4; the dual core A15s in the chromebook are already matching DC atoms.
2. you do have to wonder; how many watts can you pack into a smartphone without burning someone's hands off-- so there is a limit, and it can't be too far from today's devices! Having said that, tegra4 may well be tablet targeted anyway? or feature lower clocks in a phone; we don't really know much about it yet.
EDIT: also, i really don't think we will see much from the OEMs on this front, unless it becomes an in thing at some point. It is hard to successfully push anything that doesn't have a well understood metric to it (like screen resolution, cores, clock speed) The issue is really one for the SOC guys (samsung, nvidia, qualcomm etc) and CPU designers (ARM, qualcomm, apple); we may see some movement if apple makes good progress and starts to use the fact heavily in marketing. Just look at the razr max; not efficiency exactly-- but battery life. And that didn't have much of an impact.
As did the Tegra 3.
Android breaks down battery use stats for each part of the phone; it really depends on what you are doing. But for the normal phone use; a bit of web browsing, simple apps etc, the screen dominates power consumption (say 70%).
