Here's something you can do if you really do want to save some juice. Download and install http://www.vijay555.com/?Releases:VJEschaton - map the displayoff link to a hard button (I use the ie button) - then you can just hit that hard button while you're in a call, and hey presto your screen is off. Not just the backlight, but the whole screen. Hit the power button to bring the screen back on. |
Schettj,
Good advice, although your current number is a lot higher than I measured with acbPM a month ago. Here were the basic numbers, with nothing else running, radios off:
(BL Level/mA) - 0/38, 1/54, 2/57, 5/66, 10/81.
Basically, the lowest backlight level (which I find suitable for most indoor conditions) draws around 15 mA, and the draw increases by around 3 mA per step up to the maximum Backlight draw of around 45 mA. (I subtracted out the 38 mA baseline in these summary figures).
By the way, no extra software is needed - when you are in a call, pushing the power button on top of the phone turns off the screen while you continue to talk.
