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
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.
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 Backlight see section
having the backlight enabled all the time (Activating selectivebacklight section
(page 67) 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 see
section
8.4
(page 66)). 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
