  1. Upshot: display tech dominates battery life by Anonymous Coward · · Score: 5, Interesting

    They show that power usage is:
    0.5 Watts at idle with the display disconnected
    1.75 Watts at idle with display at min brightness
    4.25 Watts at idle with display at max brightness

    They estimate that the A4 CPU uses 0.5 to 0.8 Watts when browsing the web over WiFi.

    Conclusion, FTA:

    Until display technologies make big moves downward in power consumption the consumer experience of battery life may be driven as much or more by the LED drivers, opto-mechanical design of the back-lighting, display settings and wireless connectivity employed versus the CPU itself.
