    no?

    because it’s a physics problem. how do you have the same power level as a desktop while only having a fraction of cooling capacity?

    tldr; you don’t. one or the other, son.

    not to mention how are they implementing this? dell is fucking incompetent. the dGPU (any) is going to be inefficient as fuck and this is a laptop…so is there an iGPU for use on battery or are we good with 1hr runtimes?

      The culprit is the 7945hx, due to it being chiplet, the iodie is basically a separate processor that can’t be turned off.

      USB-C probably can’t provide the necessary wattage.

      As for the battery life, I have no idea. I have a Lenovo Legion all-AMD and it’s been quite good. The successor to mine apparently can last up to 9 hours for non-gaming workloads. It sounds to me like Dell messed something up here in a big way.

      Eh its the CPU. It’s well known by now the 7945HX is a desktop class chip. It doesn’t have any mobile specific optimizations.

      Am quite confident something like 7940HS combined with the same 7900M will have much better battery life.

      Other RDNA3 based laptops that has 7040HS class CPU paired with them have class leading battery life.
