There is a tool called powertop in the standard Fedora repos: run it from a terminal as root. There is a tab (you get to it with the right arrow) called tunables, which makes suggestions for saving power. Don’t accept these suggestions blindly: it wants “Autosuspend for USB device Microsoft Wheel Mouse Optical®” on my desktop, which turns the mouse off. I find this less than useful. Powertop knows how to implement most of its suggestions itself, or you can run powertop --html to output a file called PowerTOP.html, which gives you the command lines to run. You should note that most of these command lines will only affect the current session: you may want to change /etc/sysctl.conf (for example) to make the results permanent. However, you should also note that powertop suggests echo 'auto' > '/sys/bus/usb/devices/1-1.2/power/control' to put the mouse into autosuspend mode. There’s no guarantee that the mouse will remain at that address (because USB is like that: devices can come and go, and that affects which device number they get), and you could end up autosuspending something you didn’t mean to autosuspend, like a disk. It also loves to suggest increasing the VM writeback timeout. This means that stuff you think you’ve written to disk may take longer to actually get there. With a working battery, the main thing you have to worry about there is kernel crashes (if you save something, then the kernel crashes, you might not have your saved work on disk). None of this is Fedora-specific, by the way.
