sansa e260v2 battery benchmarking

[OkoSanto]

I noticed the unrealistic remaining battery lifetime estimate on my sansa e200v2, and I found this (http://forums.rockbox.org/index.php?topic=23915.0) thread explaining that this is simply to say that the feature hasn't been implemented yet.

Should I provide a battery benchmark, or aren't they needed anymore? (There are already 4 benchmarks on the wiki page)

I added runtime estimation a while back:
