Two more ways to save battery (if solutions can be found)

[snovvman]

1) I don't use the device in landscape much and would like to be able to shut off the g-sensor/accelerometer when it's not needed (since it is drawing power and active all the time when the phone is on).

I came across this:
HKEY_LOCAL_MACHINE\Software\HTC\HTCSensor\GSensor\ DeviceAvailability

I simply don't know if, by making the sensor unavailable, it would stop the power draw from the sensor, or does it simply make the sensor's output unavailable to the applications. It would be interesting to know the results if someone actually tests this.

2) The light sensor's screen brightness adjustment is limited. It does not (for me) dim the screen enough when indoors or when the ambient light is low. If it can dim the screen more, there is a marginal amount of battery that can be saved. I noticed that, using the light sensor, the minimum draw is around 90 mAh. With manual control of the backlight and turning it lower, the minimum draw is around 60 mAh.

I see a few registry settings related to the light sensor (under HKCU\Control Panel\Backlight) and wonder if there is a setting that can change the bias of the sensor to increase its adjustment range, especially toward the dimmer range...

Clearly, though, having the light sensor "poll" all the time takes power too...

Your input is appreciated.

i lowered the gsensor poll but woul d love to turn it off completely...ysing advancedvconfig i was able to turn off the light sensor...ill keep digging and maybe between the two of us we can figure it out as gsensor also draws ram too

i cant believe you are worried about ram juggs...

ram actually relates to power...the less available ram the more draw on the processor the more draw on the battery

ok so after changing both device avail to 0 and it disabled the sensors entirely hopefully this will help with battey im currently at 84% ill report back at 430 and let you know how its dropped...then ill turn them back on till 830 and report the drop

Thanks. I didn't know Gsensor also takes RAM.

I wonder, if by disabling the reg value above, will it reduce the amount of RAM consumed after reset? That might give us a clue whether the sensor is active at all. I will find an accurate RAM reporting tool and give it a try.

I also made a post over at the Vogue forum, asking about the Touch's backlight adjust application. The app gives four steps of brightness but does not quite have the appropriate gradients for Diamond. I'm wondering if the four steps can be altered to different values.

before changing reg attributes ram usage was 45% after the change and a soft rest 35% ram usage

You could just as easily increase the polling interval to a rediculous number, but either way, those two features will offer minimal to no battery savings.

UMM??? WHAT???????!!!!!

More RAM in use = more running processes = more CPU use = more battery drain. That's it.

Going to shut mine off too, I never use it anyway
