    I don't know what possessed me to do this yesterday, but I decided to test the battery in my Moto X and see what the battery life difference was between the dimmest setting and the brightest setting for the display.

    Fairly simple setup: For each run, Cell radio was on, WiFi was on, Location Services was on. No other apps actively running. The phone was charged to 100% each time. I streamed the same 12-hour YouTube video each time, running it continuously until the battery died. First run was Brightness @ 100%, Second run was Brightness at... as low as it goes on this phone.

    Results
    Brightness at 100% - 5 hrs, 0 minutes.
    Brightness at 0% - 6 hrs, 11 minutes

    I was a little surprised by this. I kind of expected the difference to be greater than the 25% additional screen-on time that I got. I thought it would be in the neighborhood of 40%. Is this considered a normal result? Does it have something to do with AMOLED technology (do pixels that are "on" consume battery life regardless of brightness?)

    Don't know if anyone's gonna read this since the phone is now more than 2 years old, and this page has been pushed into the "Other phones" category, but here it is. Anyone else recall doing an experiment like this and seeing similar results?
