Backlight Battery Usage!
 

Well I got bored, so I decided to see how much of a difference in the battery usage the backlight made at different settings. And this is what I came up with.


All Radios Off

Full Backlight - 71 mA
Lowest Backlight - 43 mA
Backlight Off - 22 mA


So it seems that the backlight does make a noticeable difference in the amount of battery used at one time. These tests were done using acbPowerMeter with all radios off.

lol you must of had a lot of time on your hands! but thats very interesting to know. im glad mine lasts all day though with backlight second to the highest notch and bluetooth running all day.

Backlight in any mobile device is always 50-70% of total power budget.

I always run my wince devices at the lowest possible backlight setting I can stand, maybe that's why I always get "good" battery life.

Nice to have the hard numbers tho - thanks! What's the drain one step up from lowest?
