One thing we want to do for the next versions of GNOME and Fedora is to improve battery performance. Your laptop may well be advertised by the manufacturer to have “up to 10 hours of battery life” or some such claim. You probably don’t get anywhere near this.
One major is to port GNOME Battery Bench to Wayland. But we strongly believe that making general improvements, new benchmarks and tests is also very important, maybe even more important than the port to Wayland. The main benefit is clear: to record and track battery and energy consumption with the ultimate goal to reduce those. With the benchmark done and the test, we will try to check and solve the issues that were found out with the new data (disabling peripherals unused, for example).
