Battery drain while plugged in

If I am playing an intensive game the battery will slowly discharge. I switched to a 100w charger but the issue still remains. When this happens the plug also gets really hot from trying to charge and power the system at the same time. 

the TDP also is not working correctly and I think this may be the issue. I’ve seen the wattage spike to 40w during gameplay but usually sits at 32w. The built in settings basically do nothing.

any ideas?

  • What is the game you are playing?

    If I have it, I will try to see if I can duplicate, but you need to provide more detais.

    I have a Anker pack that shows the drain.

    Even when I have the BIOS setting to "slow" the pack repots drain of 98W, I usually plug the pack if the internal batt is about 30% or so.

    After the internal Bat chanrges I see drain go to the 60, 40, 30 W etc.

    The plug will get warm, but not hot, I use a thunderbolt 4 plug rated for 130W, being U are using a brick, not sure what to make of it, are you using the "original" power brick?

  • I’ve been playing Kena Bridge of spirits and Daymare. It happens with both the stock charger and the 100W.

    I have the power go from the charger to an extension that goes to a USB 3.2 hub and I think the culprit may be the extension cable. I think it’s 60 watts so I ordered a new one. 

    I will also try changing the charge mode as I did notice it was set to low when I was looking through bios menu.

  • Ok

    I will get Kena loaded and report back

    But ... +1 on the comment made by EvryGama, I have a feeling is the USB-C extension.

    I used "trusted" brands, like Cable-Matters, Anker, JSAUX.

    I had some bad experience using generic USB cables on the Steam-Deck (which I sold on ebay for the Go)

  • One more detail I wanted to ask, have you noticed if the cable gets hot when you plug the device and battery laready is partially drained? Let's say 30% left?

    Or does it happens regardless?

    Reason for asking today as I tested I started with the battery at 65%, and it was charging very slow, but it charged a bit as I played, and it did not even get warm. But I have noticed the plug slightly warm if I have almost no juice left. I guess something to consider.

    And not sure if this is a dumb question, but seems you have a extension + Hub, does it make any difference if you hook the adapter directly without anything else?
