I had a 2023 ASUS Zephyrus G14 (AMD 6800 + 6900HD dGPU) and I took a battery hit, but not near what you saw. Somewhere closer to 20-25%.
It’s bigger problem was it was far too eager to trigger the dGPU, especially with accelerated graphics in browsers and the like. So I ended up running it in integrated only mode, unless I wanted to play games.
