Hello guys,
ASUS Tuf F15, i7 12700H, RTX 3060. While "Plugged in" and gaming.

From my observation, the dropping of i7 12700H power consumption from 45 to 25 Watts, happens only when the battery drops from 100% to 99% while gaming when plugged in. Which causes the reduction of total power draw.

The screenshots below show the average power of CPU and GPU before and after the battery reaches 99%, you can see the battery level in the last column.
Avg clock speed of the CPU decreases as well.

This causes a performance drop in every game significantly.
The CPU Electrical design point becomes "YES" when the battery drops to 99%.

BIOS is Updated.
Drivers are updated.
Win 11 Home
Performance power plan
Basics covered.

Any way to fix this?

I just had a better look at your screenshots. It is not power limit throttling, it is EDP throttling. These two types of throttling are completely different.

In ThrottleStop, check the MMIO Lock box and set Power Limit 4 in the TPL window to a value of 0. This can help with some types of EDP throttling.

Unfortunately, these 12th Gen CPUs are locked down so there is no way to increase the IccMax value in the FIVR window. You might be out of luck fixing this broken by design laptop.

Look at the max cpu temperatures.
His screenshot shows that it is not a thermal throttling problem. It is an EDP throttling problem. This is caused by Power Limit 4 being set too low or IccMax for the core and the cache being set...

A technician cannot fix this problem. Your EDP throttling problem is by design. Laptop manufacturers have been doing stuff like this for years. By limiting the amount of current available when the battery is being charged, this allows them to spec and ship a smaller power adapter. If they can save a couple of bucks with every laptop they sell, they make money.

My desktop computer runs at full speed with zero EDP throttling, ever. There is never any legit reason for non stop EDP throttling. Asus is just trying to cover up or protect some under designed components. The EDP throttling scheme that Asus is using has your CPU running at barely half of its 45W TDP rating. That is wrong. If Asus is not willing to release a BIOS update to fix this limitation then they should be willing to refund you all of your money. Find a better laptop model from a different manufacturer so you can fully use the 12700H.

Recent MSI laptops tend to be more enthusiast friendly. No matter what you buy, you have to fully test it when you first get it home to make sure that it can run at the advertised specs.

I uninstalled the Armoury Crate software now the EDP throttling is gone.
However, without Armoury crate the GPU no longer boosts to 130 Watts, gets limited to 100 Watts.

And lost Fan control options and MUX switch as well.

LOL

Shady ASUS/ Manufacturer practices.
