That doesn't help either, but even for non-native stuff, the Haswells are about on par with Cortex-A15s (if Chromebooks are any indication) - and the Cortex-A15s are pretty much non-starters in the "small device" category, which is why Qualcomm's Krait architecture has become so dominant even in devices that are wifi-only. (See Nexus 7 2013 version)
Dual Cortex-A7s seem to be the "go-to" for wearables nowadays, providing similar performance (at greatly reduced power consumption) compared to the dual Cortex-A9s of the OMAP4. There are very few dual-A7 solutions out there, so the go-to seems to be to disable two of the four cores of a Snapdragon 400 (quad-A7). Nearly every Android Wear device except the Moto 360 is using a "crippled" Snap400, and the Moto360 keeps getting slammed for battery life due to being an older OMAP3. (One of its updates greatly improved that, but the "crippled" S400s still win as even on the same manufacturing process, Cortex-A7 is much more efficient than A9, and the A9 is more efficient than the A8 in an OMAP3. Add to that the S400s being on a 28nm manufacturing process instead of, if I recall correctly, 45nm for OMAP3/OMAP4.)
