I've seen in the general section that the auto-brightness feature of Z2 is very controversial. I'm of those who find that the screen is a little too dim even with auto-brightness set at its max. Hoping that this will be fixed in a future firmware.
I've tested Lux Auto Brightness and it works very fine as a replacement as the built-in stock autobrightness. It is quite reactive and the brightness can be easily calibrated.
It is not free though.
I agree, LUX works far better than the default system function.
However it needs some tweak to be perfect; as sometime it chooses to dim the screen a little too much

Yes, a profile must be created and edited. This is the profile I've created:
Lux / Brightness
0 / 50%
35 / 70%
1000 / 100%
+ log interpolation (default)
+ 5% Jitter percentage
+ brightness variation speed: normal
It's fine for me
Wow that's brighter than me
My configuration is a bit overkill though :
0 -35%
10 30%
20 35%
35 40%
45 50%
60 60%
700 75%
1400 75%
10000 80%
13000 100%

Yes, this is why I found that the stock autobrightness was to dim even set at its max.
I've modified my profile a little, stretching it from 50% to 100%, it's better like that.
For those of you who already have Tasker, this can be quite easily done using Tasker as well. For me, I set on auto-brightness but with slider to the max. This suits me for most occasions, except when it's really dark, in which case I find it too bright. So for me I just have 2 simple profiles on screen unlock if the light reading is less than 5, set brightness to 0, otherwise set brightness to 255.

What's the LUX values you are using?
Sent from my D6503 using Tapatalk
The Lux are on the left of the percentage, however I changed my settings. I like it brighter
0 // -35%
2 // 20%
10 // 50%
60 // 60%
800 // 80%
10000 // 100%
I don't know why but I can't get the setting right. The screen is either way bright or too low. Now I reverted by to the default values. [emoji26]

Thanks for this. Just got mine yesterday and noticed the brightness issue right away. Gonna give this a try.

Tried LUX and it works quite good for me, but it overrides the setting to keep the screen alive while you hold the phone in your Hand.
Has anyone noticed that too?

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.

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.
---------- Post added at 11:28 AM ---------- Previous post was at 11:21 AM ----------
+ 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.
I heard that auto brightness consumes more battery
But its also something exclusive to our phone comparing to the s3 mini
So, do you guys think its worth using??
No, if you want to save battery. Btw, I don't think you need to open a thread for question like this..
For a long time I used autobrightness, but now it seems to be better if I change turn the screen brighter when I need, or if the sun shines so bright, any other time my brightness is on minimum.
What i do is:
Brightness- lowest most of the time
outdoor- auto when i want
Btw, for dialling no.s quickly i used a tasker profile (when i launch phone/messaging b/w 8am-6pm it sets auto brightness on)

For those who don't know , tasker is an app which is used to automate your phone. (It uses an"if this then that" logic.
Search Google play for tasker.
Such a setting is called a profile.

I always have brightness at 100 and still a good battery life

Auto brightness is constantly using the sensors to gauge the brightness levels so is no good for battery life.
Use it only when needed like outside in sunlight.
Indoors minimum brightness is fine and is much better on battery.

Sensor should be shutdown when screen is turn off and active only when screen is active. The easiest way would be check interrupts in kernel
Code:
cat /proc/interrupts|grep sensor_name
. If it generate a lot of interrupts when screen if off it may cause battery eating, but then is fault in driver.
I turn off auto brightness first thing. It never goes dim enough when in a dark room or bright enough in daylight. I also see battery saved when I manually control it. Been doing this with all phones I have had... just sayin'

Yes i know its only when screen on.
Would be a bit pointless with screen off
Sent from my brain
I searched and found no real answer. My question is does it use more battery life to have adaptive brightness on which allows my screen backlight to dim way more on default. I've read and been told leaving it off is best however with it off my screen can only din to what appears to be about 25 percent. Does the service running to adjust the brightness use more battery then just leaving it at its lowest with adaptive brightness off?
Sent from my Nexus 6 using Tapatalk
The problem for battery drainage with adaptive setup is when the brightness gets cranked up to high in a well lit surrounding even though at times its unnecessary. With it off you can simply apply a brightness percentage that is okay for you in most conditions like when you're mostly in the same office for hours.

Does anyone use this phone on full brightness and if so what is the battery life like? just curious because i'm thinking about using it on 100%
Thanks
Dude I'm sure using it at 100% brightness will kill your retina before it kills your battery.
Seriously though, I think they made some changes to the brightness setting in one of the more recent firmwares, because it shines with the intensity of a thousand suns now at 100%, compared to what I remember it's like originally. I used to set it at 50% brightness, now it's at 25% or so but with the same perceived luminosity level (non-scientific of course).
Do you really need it at 100% constantly?
