Is it possible to reduce power consumption of the display? I already set brightness to minimum. Power Profiler shows that the display is using about 75% of total power consumption when phone is idle with wlan on.
450mW Display
600mW Total
If it is possible to reduce display power to 300mW the battery should last 33% longer.
I see only a small difference with low brightness or full brightness. (450mw low, 600mW high). No difference if Screen is white or Black. Maybe a bug in Power Profiler?
Try to set a dark background. AMOLED display only consumes power on dots that really on.

yeah,i got a better battery performance when i changed to black wallpapers

how much diffrence between Auto backlight&manual in battery consuming
is there any experience ???
nobody knows?
One week ago, I changed the option for backlight to 5 min instead of normal 30sec. I even changed the backlight on while making calls (tweak cabfile). I don't notice any more batteryconsumption. This is a overall experience.
I think more brightness on the display will be more battery consuming than backlight settings.

Thanks! I think you are right
What ever option you choose that cuts Electricity flow saves Batts.
So yes turning the screen all the way down when only doing calls and at night helps a lot!
Note also that the auto-dim function doesn't ever dim the light right down (no matter how dark it gets) - the lowest it reaches is equivalent to the manual brightness level 3.

So I just got Tasker and I've been playing around with the light sensor and I've noticed something strange. If I set the display brightness is below 12% (12% is the lowest brightness setting in display settings), the light sensor stops working. Has anyone else noticed this?
It would be nice to be able to set the display brightness to 0% to save battery and still be able to use the light sensor. I'm running Perception 10.1 with glitterballs OC/UV kernel.
(I'm using Extended Controls to set and see the brightness %)

The lowest I could go is 8% using brightness level widget. If I am not wrong, 0% would be screen off. U could use "screen filter" app to further reduce brightness at night so it does not strain eyes. This lets u go as dark as u want, even upto literally where u cannot see anything on screen.
Hey guys
Recently just got a optimus black and started playing games more, before i had a HTC dream and Magic was able to get 2 days of battery but atm, I'm getting like 4 hours battery playing **** what are the best settings on nova to get the most battery.

+ are there any apps that really help?, using juice defender just with the balanced setting any advanced settings that improve this?
Mainly 2 things consume battery:
a) CPU ~ 15%
b) Screen ~ 80%
For a) you can decrease it by using a good governor for battery, ex: InteractiveX.
For b) it's a matter of having it on the lowest possible brightness you can handle. *
* For example, automatic brightness indoors (low) != minimum brightness, it actually consumes twice the power. Twice.

Thanks for the reply, yeah don't really change brightness so i will do that from now on, also auto uv and underclocking i am going to have a play around with.
Our SoC is already underclocked with SmartReflex.
Further UV won't do much difference.
Oh to easy then.
I bought this phone bcoz of LG advertisment :"NOVA Display automatically adjusts its brightness sensing the amount of light needed, and saves 50% energy under regular settings." (compared to regular LCD). What is the selling point for tat? LG Optimus Black eating battery damn horrible. We like LG Optimus Black including the super-bright NOVA display (LG so proud of it), then why should i need to adjust the bright to lower to save my battery? What's the point???
The point is:
- If you want the brightest screen, and to use a lot the phone with the screen on, it will drain your battery a lot.
Regards.
With CM it's possible to calibrate the auto-brightness values.
I'll try to come up with a good configuration.
hello. today I saw that after playing and the screen is blackened . I always bring the manual and the maximum brightness . happens you know ?
Maybe your low battery mode was on...
As far as the device gets warmer, the screen dims automatically to prevent overheating.
I've noticed the LED brightness varies. I like my brightness to the max. I did notice one day that once the Power Saving is enabled, the LED gets dimmer. I have the Power Saving feature to turn on only when it reaches 20%. Anyways, most of the time I barely hit that mark before I charge it up again. I notice that sometimes I will have a very bright LED notification and other times it's not as bright. Is there any way to force it to be bright all the times (except when Power Saving kicks in of course)? Auto brightness on the screen is off by the way. Not sure if that would affect the LED brightness but it's off.
I am pretty sure the notification LED is also controlled by screen brightness. That way you don't get blinded at night by it. Also just so you know with auto turned off, even at full brightness you will have issues in sunlight. If you set it to auto, in sunlight you will get about 30% more brightness then you would just set at max.

I could understand that if the auto brightness was enabled, but it's not and the LED brightness fluctuates.
