    Whenever I play a game on a laptop it seems to be draining the battery even though it's plugged into the AC. Is this normal for current laptops?

    Yeah it can happen with some units. The PC pulls power faster then the battery can re-charge especially when your gaming.

    Details of laptop and also take a photo of the power brick for us?
    As said above, the power brick may be too small for the load.

    Most gaming laptops can have two types of power bricks a smaller/lighter one for general use/charging and a much bigger/heavier one that outputs more watts for gaming.

    ASUS ROG Strix Scar 2 with an i7 8750H and a 1070.

    It looks like it came with a 230W power brick.

    Funnily enough I think it is the IC or the OS driver for the battery monitor that's causing my main issue where, with the battery connected, the GPU would downclock to 900-1000MHz when the GPU load was at 99%.

    As soon as I disconnect the battery to force it to run off AC only the issue disappeared.

    My assumption is that AC overrides battery when AC is plugged in.

    the model number is ADP-230GB B so I am assuming it's a 230W PSU.

    Is it draining from 100 to 90'ish?
    Even when not playing games, I've seen a plugged in laptop battery being drained, and after some research it was something to do with battery management from Windows.

    I did have a old gaming laptop where the power draw was bigger than what the power brick could manage, so it would be supplemented by the battery. But with your 230w power brick, that shouldn't be the case. If you need to check though, just check the voltage and amps supplied (should be written somewhere on the power brick).

    It drops to about the mid-90s when I play Siege but when I was trying out metro exodus it drained so much that it caused the laptop to shut down because of low battery.

    I'll take a photo when I can.

    EDIT: I also have a kill-a-watt to measure the wattage draw from the wall.
