AMD knocked it out of the park with its Ryzen series of mobile CPUs, but there's no question that its discrete mobile GPUs have been falling behind. The Radeon RX 7900M rights the ship by being just as powerful as the mobile RTX 4080 fur hundreds of dollars less.

      Consumption when idling on desktop is not optimized which may contribute to the very short battery life. We’re sometimes able to measure a consumption level as high as 101 W even when on the Balanced power profile with no active applications running. Consumption on standby mode would also be very high at 25 W when it should be closer to just 1 or 2 watts.

      The model does not support charging via USB-C unlike on most other modern gaming laptops and so you’re essentially tethered to the ginormous 330 W AC adapter when traveling.

      Idle average was reported as 55wats, granted that’s with the crazy issues above - however minimum idle was reported at 30wats, not great…

          Laptop CPUs typically target around 1W idle. 5W is more typical for the entire system. That results in around 11h battery life.
