bit rates and battery life

I have noticed several times that the battery seemed to drain faster than it should. A 20 minute walk while listening to an audio book seemed to drain the battery about 15-20%. Is there an impact of the bit rate to the battery load? If so what is the optimum bit rate?

Thanks

What is the bitrate of the audio book?

AFAIK, the typical bitrate of an MP3 is 128Kbps.

Hi John,

the bit rate does influence battery life insofar that the cpu may have different power consumption if the task takes more calculation power. I have no idea, how strong the bit rate does influence the power consumption in terms of battery time and such.

also, do you have the play slower feature enabled for your audio book? that might also cost more power.

The bit rate is 64Kbps. It can be set in the preferences for when a conversion is done.
