Any improvements in battery life over 2002?

The Spb benchmark suite includes a battery test if anyone's willing to try:

Not exactly a benchmark, but I took my Axim on a trip the other day. In the evening I used it for about an hour, and the next day I played MP3's for approx. 3,5 hours. When I came home the battery meter showed 52%. Not bad I think.
