13.4. Firmware Loading
13.4.1. Using ROLO (Rockbox Loader)
Rockbox is able to load and start another firmware file without rebooting. You just
“play” a file with the extension
.mi4
.
This can be used to test new firmware
versions 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-
puting intense features (e.g. sound processing) or using effective audio codecs.
The
following provides a short overview of the most relevant settings and rules of thumb.
13.5.1. Display backlight
The active backlight consumes a lot of power. Therefore choose a setting that disables
the backlight after timeout (for setting
Backlight
see section
(page
)). Avoid
having the backlight enabled all the time (Activating
selectivebacklight
section
(page
) can further reduce power consumption).
