To be fair, audiobooks are also very low bitrate files. With higher bitrate/quailty music files, I’m sure more battery willl be used.  That said, it is an encouraging sign.

I guess it all depends on the audiobook bitrate, as well as the bitrate that one uses on other files.  In the end, though, indeed encouraging, where the battery is rated at 25 hours by the manufacturer and a first report ostensibly confirms better than that, in regular play use.  I’m sure that others will do their own testing and reporting, in all kinds of use.
