I have exactly the same issue and would be interested in any information to explain this.
Do you have power saving enabled? If so it will automatically reduce the brightness if battery goes low.
Glad I'm not only one
Nope not got power save on or any app which could change settings very strange would like to get to the bottom of it
The only thing i can think is maybe you dragged your finger across the status bar and manually changed the brightness setting.
I have noticed if the battery charge is below 15% the adjust brightness is greyed out in the settings and the brightness is set to the lowest level whether you have the power saving set or not, and if you force the brightness up using the power bar widget , when you phone goes to sleep and wakes up your brightness is back to the lowest setting, but as soon as you charge your phone , the brightness returns to normal.
+1 on TinderBox's comment if the battery is low (not sure how low but my test was under 7%) regardless of settings the brightness keeps getting turned down. When watching video or locking the screen etc.
Hey there,
I recently tried out the new Cyanogenmod 9.1 for Xperia Mini. I was impressed about some of the functions/improvements, especially the unbelievable bright display! Unfortunately the battery drain was not acceptable for me so I had to switch back to the standard ROM. So my question is has anybody an idea how we could increase the max brightness of the standard ROM? I mean it must be adjustable otherwise Cyanogenmod would not be able to give a much brighter display ... Any suggestions/ideas?
Thanks in advance!

Either use the ultrabrigthness mod from themes and apps section or download from playstore xperia autobrightness disable, then you can control screen brightness with toggles.
Btw, CM9 drains waaay less battery that stock, increasing screen brightness is what affects it the most..
Thanks man,
could you give me a link to the mod, couldnt find it ...
BtW, under cyanogenmod my battery drained over night like hell, so it obviously had nothing to do with the screen!
Thorsten
Here, push this file to system/etc directory with adb
https://dl.dropbox.com/u/44281412/hw_config.sh
Did you check the battery usage to see what drained the battery? CM cannot have higher battery consumption than stock, that's a fact, probably an app went haywire or something wasn't installed correctly.
will it have any significant battery drain if auto brighness is disabled??
Turning off auto brightness actually increases your battery since it's not using the light meter on your phone and constantly processing to change your brightness based on the light you are getting.
Hello Guys!!
Have anybody missed AUTO BRIGHTNESS feature in L9 because lack of Ambient Light Sensor,
If yes, the don't worry. I have an easy solution for Auto Brightness, Yes you can use Auto Brightness on LG Optimus L9:victory:
NO ROOT REQUIRED
Download and install These two app from following links:-
Lux Auto Brightness
Tasker
After Installing these apps follow these steps:-
Lux Auto Brightness:-
Go to Lux settings
Tap on Sample Collection
Tap on Select light reading source
Select Camera
Then get back to main settings menu
Tap on Mopdify linked samples
Tap on Luma TAB
Tap on ADD, set brightness (yello bar) to 4% Luma value to 1 and press ADD
Add 3 more links with these values= 35%-70|100%-80|50%-120|
Exit Lux
Tasker:
Open Tasker, tap on Plus Gign(+) on main screen
Tap on Event
Select Display in Event Category
Select Display On in Display Event
A blank screen will appear, do nothing just press BACK Button
TAP on New Task +
Enter Name to task or just tap on tick
A blank screen will Appear, tap on Plus Sign (+)
Select Plugin from action category
Select Lux Plug-in
Tap on Edit Button
Scroll Down and Tick in front of Refresh Backlight brightness? Under Force
Press Done, then press back and back again
Exit Tasker
Thats all work to do, now your dvice have Auto Brightness feature:silly:
To test, just press power button and lock the screen and then cover front camera with finger and press power button again, screen will Light up wait 1-2 seconds, Screen brightness will reduce, remove finger, lock unlock screen and brightness will resume to normal.
I have tested this for full day on my L9 and got no any battery drainage.
You can modify Linked Samples Values to your comfort zone for batter sample values you can also search other XDA forums.
Guys try it and let me know how you feel
if you got any issue please post, I'll try to solve it (Coz m also new to TASKER & LUX so may be it will take little bit time to Solve:fingers-crossed
EDIT: You can uncheck "Presistent notification" in general settings of Lux Auto Brightness, If you think it is draining your phone's battery. This will also disable the annoying Lux icon from notification.
HIT THANKS IF I DESERVE IT
Another mod we miss in our L9 just got fixed.
thanks for sharing
i'll try it as soon as i can and report back.
Is this battery hungry workaround ? Two apps must run in background so they must eat battery .
Is it possible to have a refresh .. for example every 10 minutes camera will check light to set brightness?
Found it's in lux settings!

No, I have tested this yesterday for full day and haven't noticed any battery drainage coz of these apps. According to me, besides draining battery this MOD should save battery by adjusting it according to Ambient Light.

Yes Mr.Brown, you can set automatic refresh in general settings, but I'll never suggest you use automatic mode, it could drain your phones battery.
Do not use lux with easyeyez it will slow down your phone too much

Yes bleuwavem you are absolutely right, that's why I am using tasker to initiate refresh process on display on. If you use lux individually then it will slow down your phone and drain the battery. In my tutorial actually lux is not running in background (if it is running you can kill it). Tasker plug in triggers it to refresh the brightness. Coz i have used it for hole day and currently using, I have not face any issues with device performance. If anyone body faced any issue can post here i'll try to solve it.

How to set min brightness 40% in LUX ? How works those luma settings ?

in which condition you want set your brightness 40%. Like if you want to set brightness 40% in normal day light then, when you are in normal day light, go to Lux, tap on modify linked samples, tap on Luma. Here you will see Current Value: with some digits showing. Now here hold your phone in normal light and click on "tap to refresh". it will say reading for a second and then it will show you a value, mine was 118. Note that value. Now tap on add at the bottom. In "Add custom link" box, drag and adjust brightness (Yellow Bar) to 40% and in Luma enter value you have noted. then tap on Add. thats all, now your normal daylight brightness is 40%.
Try it:highfive:
My device works just wake mod only....i do not understand why need tasker app, works without
Noob Question: Why does a lux value of 120 set a brightness of 50% in the tutorial? I've set it to 100% for now till you reply.
Great solution OP! Also, why do we need tasker to force display brightness when there is a setting for adjust brightness on wake in the lux settings? Is it because it doesn't adjust it sometimes?
---------- Post added at 11:01 AM ---------- Previous post was at 10:55 AM ----------
I've also noticed that direct sunlight throws the lux reading off....(lux value becomes lower in direct sunlight than in shade in the same area)

Yes bleuwave your right, I used Tasker for two reasons, first as you mentioned Lux's auto brightness Don't works some tims, so tasker force it to adjust. Second reason is this that using tasker you no need to keep lux app running in background, coz if we keep it running in backgroung it will slow down phone performance and drain it's battery. Using tasker you will never miss auto adjustment

i have set 50% Brightness with value of 120, coz 120 is normal day light reading, so in normal day light 50% brightness is good enough to see the screen. 50% brightness is also no drain battery.
Yes this behave of lux also amazed me. it shows light reading value 80 in direct sunlight, in shade it shows 120. But the settings i have done, are working like charm even in sunlight also. as per my observation reason of low reading value in direct sunlight may be auto brightness setting of front camera ....What do you think about this..
Thank you very much....now my phone has auto brightness

Hmm ... it is strange today Lux Auto stoped - it just don't work . And I must say that combo of those to programs eats battery ,maybe for the reason I have not stock kernel ?
5% per hour vs 2.4% per hour with out them running .

Yes sebx its strange, Stock kernel may be an issue for this. I will suggest you to change some settings in Lux, keep every thing disabled in Lux settings, because Tasker is enough capable to run its services automatically and keeping everything disable in lux will reduce battery consumption also, so change setting and try it again.
Dear Canvas HD Experts:
Anyone noticed Automatic Brightness issue in 4.2.1 even in earlier versions? I noticed brightness is up and down very frequently which is very annoying. Even if I hold the phone in a same outside brightness brightness is going up and down
Appreciate if anyone come-up with a solution for the same.

It is a known bug. Can not do anything about it. Just uncheck auto brightness option and you are fine

I am not having this kind of problem however I have noticed that when my phone's battery is 10% left my screen brightness turns up to full on automatic brightness mode so I have to disable it whenever this happens.. other than that no issues at all with auto brightness feature.

I think something wrong with the firmware itself.
Hello smart people! I just got the phone yesterday, super excited about the custom roms! My question the scrren keeps dimming while im using the device. It not only just dims but it acts like it tries to go to sleep, While im using it! It wont Reconize any touch, till i kinda wake it up. It does this multiple times a day. My brightness is set to auto, figured it might help with the battery drain, but other than that i'm not sure what setting I ticked to get it todo this.
BTW: I'm not rooted, nothing weird on this device, just apps

Auto brightness will definitely help with battery drain, but probably not in the way you're thinking. Pretty sure turning off auto brightness will help with the fading, but we'll need more info as far as diagnosing your lack of responsiveness to touch.
What (if any) case do you use/do you have a screen protector of some sort? Is it when you are outside in the freezing weather that you notice a lack of sensitivity in your touchscreen? Do you have any "battery saving" apps that you're currently running?
I didn't think about the battery saving apps causing this
Do you have Paypal installed? If so, uninstall it
Auto birghtness on LG phones is terrible. Try installing Lux Auto Brightness on the store, it's a lot better. Also, you can set your screen off time in the settings higher, it's probably set to stock of 30 seconds
Lux is what I use.
