without deleting your current version.
13.5. Optimising battery runtime
Rockbox offers a lot of settings that have high impact on the battery runtime of your
player. The largest power savings can be achieved through disabling unneeded hardware
components – for some of those there are settings available.
Another area of savings is avoiding or reducing CPU boosting through disabling com-
