Thanks for the update shockingpants. I've been following the Lenovo forums as well and am dismayed by their lack of acknowledgment of the power issues.
Just wanted to chime in on a couple of things.
1) I would perhaps try to find the most recent Dell drivers for your wi-fi card. I swapped in a DW1830 instead of the DW1560 (added an antenna) and with the latest bios update and wifi drivers, I'm getting better battery life on Windows (~6-7 hours at 40% screen brightness.) Still testing, but will update as I learn more. I can't recall exactly how I found the most recent 1830 drivers, but it took some digging through the dell support page (i.e. not just a google search).
2) In case anyone is curious, I tried implementing the linux sleep patch for the X1Y3 (https://gist.github.com/rickybrent/1dabaf78ad03c290aa97489bef7d36fb) by going through the DSDT post-patches and deleting / adding the requisite sections. Doesn't seem to have much if any impact. System sleeps, but battery drain is still significant.
I'm holding out hope that the next major update of the Bios (1.30) contains the sleep fix like it did on v 1.30 the X1C6. Seems like this "modern sleep" is not quite the advantage that Lenovo thought it would be ....
