I can also confirm this one also on a HP 15s-fq4xxx series laptop I tested this on the kinetic kernel 5.19.

Kernel version went from 5.19.0-43 to 6.2.0-20. Running powertop, I see that C8 is being used with 5.19 but 6.2 does not go to a higher power saving state than C3. I tried the Ubuntu kernel from jammy ie 5.15.0-73. It also uses C8. I have also tried the 5.15.108 & 5.10.17 mainline kernels. Both of these do not go to higher power saving state than C3. All these tests have been run on the same partition ie. only the kernel version has changed. Laptop is a HP 15s-fq4011TU 11th Gen Intel with Tiger Lake Iris Xe graphics. So it seems to me: 1) Ubuntu has applied a patch to the mainline kernel that improves power saving in 5.15 and 5.19 2) This patch either hasn't been applied to 6.2 or no longer works. Could you pls let me know what other info you need or what I could look at next?
