Stephanie Wingate has posted the results of a real world battery life test on 
her web site, http://www.wingfieldaudio.com  This is the most comprehensive 
test of battery life in pocket-size audio recorders anywhere!  Thanks to 
Stephanie for her hard work.

Stephanie tested all 16 recorders that she sells. To make sure that the 
recorders would not run out of storage space before the battery expired, 
digitization was set to MP3 format at 128 kbps.

Because the Sony PCM-D50 and PCM-D1 units don't record MP3, they were set to 
capture WAV files at 16/22.05.

Results:
first place.....Sony PCM-M10...43.0 hours       
second place....Sony PCM-D50...25.5 hours       
third place......Olympus LS-11...19.2 hours

See the web page for the rest of the results

Of course the results would be different if the recorders were digitizing at 
24/96 (writing more data per second uses more power), and providing plug-in 
power to external mics.  But the rank order is unlikely to change.

Thanks to Tapers Section participant "labello" for bringing this to our 
attention.
