I'm in the same boat, looking for as light as possible with a much battery as possible, was banking on the 16 yet we get 9 hours instead of (an assumed) ~10-11, and 2.1/2.4kg.
Somehow the Thinkpad Extreme X1 and the new Zephyrus G16 have similar CPUs, dGPUs, a >90Whr battery and they weigh less than 2kg.
Where's most the weight going? Will I be able to buy a FW 16 and eliminate weight to achieve similar specs? Literally asking about using a "stripped down version".
If you want the lightest laptop with the longest battery life, you'd get a Mac. If you want the best bang for your buck go with a basic Ultrabook. If your willing to have a bit more weight, size and a bit less battery in exchange for repairability/customization, that's the niche framework fits well.
As a result, its beginning to resemble a paperweight.
For Linux, when following our installation guides for power optimization, power consumption with integrated graphics should be similar.
Edit: Tom's Hardware similarly reports 9 hours on Windows (with Graphics Module installed): https://www.tomshardware.com/laptops/framework-laptop-16-rev....
