Hi, I have heard that WMA uses more battery power in MP3 players (I have a Sony E465) and I was wondering does that only apply to DRM WMAs? or does 'regular' WMA files use as much power? or more power than Mp3?
Thanks in advance

Power used often depends on the bit rate. IF you believe M$oft ads, you will use half the bit rate in WMA for equivalent quality. Big "if." As Saratoga said, best way is to try it. play a song on repeat from full charge to dry with each format. If your player has a hard drive then consider a longer playlist so disk caching won't just keep the drive from spinning up on the repeats. To give you an idea of variability there are some benchmarks on rockbox.org, but I'm SURE no DRM format is included. |
