Intel Core i7-10510U not going deeper than C3 state

I have this CPU model

CPU: Intel Core i7-10510U (1.80/4.90 GHz, 4 core/8 thread, 8 MB L3, 15 W).

GPUs: Intel UHD Graphics 620 + NVidia GeForce GTX 1650 Max-Q 4 GB GDDR5.

Since the battery discharge time is drastically lower than just a few months ago, I tried to check with powertop if something was wrong. I noticed that the section Pkg(HW) does not go deeper than C3.

On the other hand, the section Core(HW) reports that all the cores spend most of their time in C7 state.

How can I diagnose the problem?

EDIT:
I additionally report some figures from powertop

The battery reports a discharge rate of 16.9 W
The energy consumed was 350 J

Hi,

Could you install netdata?
I am yet to figure out about the C States, but will get there.

It looks something like this from the web, you will need to create a dashboard. Each dashboard will have a histogram of almost everything, so you will not be stuck with 1 dimension of data.
