Real-life battery tests: Sony HD5, iPod photo 4G, iAudio X5
The test is pretty simple. Charge it up, leave for 48 hours, then play back my test MP3 library which has a wide range of songs, the lowest being 128Kbits and the highest being 320. All effects off, all EQ off. The volume is adjusted to slightly louder than I would normally listen to on a pair of Sony MDR-V700DJ headphones. I also simulate some fiddling by ‘using’ (i.e. navigating without changing playback order) the player for about 10 seconds at a time for 10 times throughout the testing period. The backlight is enabled for at least 10 seconds after key presses on all players.
Sony’s HD5 gave up after 21 hours (instead of the advertised 40), while both the X5 and the iPod lasted for 14.5 hours (the former’s battery is supposed to last for 14 hours, while the latter should give you juice for up to 15 hours, according to the company’s statements).
Of interest is the fact that the HD5 gets into sleep mode quickly, so no potential battery drain issues here. That’s in contrast to Apple’s player that wakes up fast.
