I’m beginning to doubt that I really do have an OLED screen on the OQO 2+ here because the power drain test I just performed showed some relativelt poor results. I knew that OLED screens could be tweaked for power or brightness but I didn’t expect to see so much of a difference in my power-drain test results. There really isn’t any power advantage over LED in this case and with amazing LED-backlit screens like the one on the Wibrain, you wonder why they did it. Did I just hear someone say ‘marketing’? Keeping things in perspective though, these results are ‘good’ but just not as good as I expected.
The first image show power drain as measured by Vista’s ‘performance and reliability monitor’ in battery-saving power profile with the OLED brightness turned down to minimum.
This image shows the graph for the same setup but with max OLED brightness.
Be aware that I’ve got a production sample OQO+ here and again, don’t forget that in the big world of mobile computing, these results still represent amazing efficiency.
From the drain graphs above, you can calculate how long the 17wh battery will last. I’ve written a bit more about this over at MID Moves.
As always, full specs and more links available in our product database.
