With the voltage optimisation on CPU+GT+SA, and the SATA replacement in place, I'm now getting 8h (avg consumption 1000mA) on regular usage, using full brightness and QHD. Pushing some optimisation further (down to 800mA consumption) I'm seeing 10h, see the attached.
There are a few other UEFI tweaks I'm testimga to the moment which force GenX mode on all PCIe devices and ASPM on NVMe. If these are fully stable they'll probably get a further 5-7% battery saving.
I've left touchscreen enabled but tbh macOS doesn't benefit from it (it actually hinders it), and I'm not that ecstatic on seeing fingerprints on the display under Windows. Besides using proper keyboard shortcuts has always been faster, at least for me. YMMV...
That said if you're not rushed I would hold out for the new XPS 13 with coffee lake and quad core, the benchmarks look v encouraging...
