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
.iaudio
.
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 computing 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

see section

)). Avoid to
have the backlight enabled all the time.
12.5.2. 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
continuous playback (see section
7.5
(page
56
)).
12.5.3. Replaygain
Replaygain is a post processing that equalises the playback volume of audio files to
the same perceived loudness. This post processing applies a factor to each single PCM
