I don't understand why Microsoft doesn't give the option of AMD processors that have better performance in both CPU and iGPU. It is clear that the competition has taken away many sales, such as the ROG Flow Z13 (2025) GZ302, a truly crazy ultrabook that no one has yet surpassed.

"a similarly equipped Zenbook S14 nearly achieved these runtimes during our tests using a 72 Wh battery."

Except that your battery tests are BS.
During your Zenbook test, you measure 6.2W average.
With a 72Wh it gives 11.6 hours... of IDLE, so doing nothing.

How can websurfing gives 14 hours, so higher runtime than idle ?
And websurfing with max brightness gives 10 hours.

Other reviewers on the Internet have much much less.
