First, please refer to this question

I have almost the identical model with the same specs:

AN515-57-55R8

I'm also experiencing the same issue. Spent an hour on chat with a Nvidia tech. I sent some logs to him and his best advice was to update my drivers. Said I had the latest from the Acer website. Also told him this appears to be a simple tweak of the GPUs power state. Read below to understand what I mean.

I had used the same install with the model below this laptop which had an i5 10300H and RTX 2060. That laptop down clocked to the lowest setting when idle or no 3D apps were running. Power from the wall was 30 watts when idle.

Try this to see if your 3060 down clocks:
Open up Nvidia control panel by clicking on the icon in the system tray. There should only be 3 options. Make sure "Adjust image settings with preview" is selected. In about 5 to 10 seconds, your 3060 should down-clock to 210 MHz. If you select either of the other 2 options, your GPU will boost up to 1425MHz. On my laptop, going from idle to boost clock with no load doubles the power used by the GPU! Close NV control panel and it will stay at 1425MHz. If this happens to be the case with your laptop, then that will confirm what I said above.

If you use a certain version of Nvidia Profile Inspector, you can see the current clocks of your GPU including power states. When the GPU is at idle clock speed, the power state is P8 (lowest). When the GPU is at 1425MHz, the power state is P0 (highest). I think there are only 4 power states (P0, P3, P5, P8).

Been Googling for some time, still no answer...
I have literally the exact issue, just bought a PT516-51s on Windows 11 and the battery performance is bad, when the GPU is Idle, (inactive in the NVIDIA's notification pane) the GPU clock is at boosted clock (?) 1425Mhz and the power consumption sits around 20W~ for the GPU alone, if I open any programs that use the dGPU without put the load, the clock down to ~210Mhz and the power draw reduce to around 11W~. As soon as I close the program, the problem happened again. I think the NVIDIA Optimus thing is not working as expected.
I tried everything, update BIOS, drivers, but nothing helped.

Please let me know if you got a solution for this... I've been searching on this problem for a while, but no luck.

    Have a look at this guide “NVIDIA Optimus” of how to set NVIDIA Optimus up properly as you must have its settings wrong or you need to set this up properly.

    I've already uninstall GPU with DDU then install with clean installation. I don't think its a setting issue :(
