12.4. Firmware Loading
12.4.1. Using ROLO (Rockbox Loader)
Rockbox is able to load and start another firmware file without rebooting. You just
“play” a file with the extension
.gigabeat
. This can be used to test new firmware
versions without deleting your current version.
12.5. 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.
12.5.1. Display backlight
The active backlight consumes a lot of power. Therefore choose a setting that disables
the backlight after timeout (for setting

having the backlight enabled all the time (Activating

section
(page
) can further reduce power consumption).
12.5.2. Display power-off
Shutting down the display and the display controller saves a reasonable amount of power.
Choose a setting that will put the display to sleep after timeout (for setting
Sleep

section
(page
)). Avoid to have the display enabled all the time – even, if the
display is transflective and is readable without backlight. Depending on your player
it might be significantly more efficient to re-enable the display and its backlight for a
glimpse a few times per hour than to keep the display enabled.
12.5.3. Anti-Skip Buffer
Having a large anti-skip buffer tends to use more power, and may reduce your battery
life. It is recommended to always use the lowest possible setting that allows correct and
