Well got irritated in the end, so had my N900 play 1 Hour video, then jut keeping the display on until i saw 3.3V
It really felt like it was never going to die!!!!!

Runtime as you can see in the graph was 32hours+, at very high load it should still be able to do at least 10hours, and when i say very high load i mean an average load of 85% approx over the 10hours.

But here's the graph, and you can see in the end i just kicked it's a*s
Also included a zip with the jpg for full detail (no downsize....)

Also notice the charge rate before full battery.
Right now it is charging with 2.5A and in just 10minuts it has charged up 416mAh or 30% of a normal 1320mAh battery


EDIT: this info will be added to post #2 also
