Automatically change power modes>

Still reasonably new to Fedora/Linux so apologies if this is an easy fix or I’ve missed something.

After distro hopping on my desktop pc for the past 6 months have settled with fedora and decided to install it on my laptop as well. All going fine but am having some trouble with power modes/power management profiles on the laptop. I’ve turned on automatic power saver for when battery power is low and that’s working as expected. I believe the battery threshold for this is in etc/upower/upower.conf and have that set to 15%?

However, if I switch to AC or charge the laptop for a period the power profile doesn’t automatically switch back to the previous profile and I have to change it manually. Is that expected behaviour or is there a way to set it so that if I’m on AC power or the battery reaches a certain threshold it swaps to the performance or balanced profile?

Ideally I was hoping to set so its something along the the lines of the performance profile by default when on AC and then balanced when on battery and greater then 15% battery life but not sure if that sort of fine tuning is possible?

I’m using an older Dell XPS model and have some battery saving settings turned on in bios so not sure if that’s causing problems either? Have had a look around the forum and can see there have been some issues with not being able to change power states but that doesn’t seem to be the problem here as I can change them manually.

I use TLP and it does what you want. You can tweaks everything with it. TLP is well-known to customize you profiles, automatically switching profiles. It is way better than ppd or tuned-ppd. If you want to try it, first learn more of it to not conflict with your system. Believe me or not, you will understand, not only does it control your cpu governor like ppd, it controls every single hardware, switches between AC and BAT easily. But you need to remove other tools like ppd or tuned-ppt not to conflict with tlp
Here is my config, tlp-stat:
