Battery test on 4GB
So, I decided to see what the battery in this little devil (4 GB) would do, straight playing. I fully charged it using my after-market, wall charger. Set the volume where I ordinary listen and let it run. Started at 8:30 am. Listen sometimes — checked to be sure it was always playing. Played with it enough during the day to match probably what I would do on a long fight from Los Angeles to, let's say, Paris. (Which is the kind of thing that's important to me). It finally started blinking at 4:30 AM. Then went down at 4:45 AM. That's about 20 hours? No so bad.
