Just I have checked the screen shots of battery usage published here, and my own experience of usage of phone.
As the result I can conclude that the main consumer of power is the screen. It's not very genius to found this, but the significant what was found is the opportunity extend battery life due to this.
As the root was recieved, and also Sony reacts our posts with new updates, so l hope our attempts will meet result.
The main issue lies in the field of regulation of brightness of screen, even with manual regulation the lowest brightness is Very High.
During manipulation with check box of automatic brightness one can see that brightness can be set lower and in usual cases the lowest brightness is enough and in night it can be set more low.
So if somebody understands where this regulation may be adjusted, please explain it. how to do this adjustment or try yourself and share results. I think that it will extend the battery usage dramatically.

I have ongoing problems with eyestrain. Back-lit screens seem to be the issue. Have you found the SGS2 better or worse in regard to eyestrain, if this is an issue for you. I would really like the SGS2, but I may go with the Sensation if its screen may be better for me. Is max brightness on the SGS2 bearable? Reducing brightness seems to increase flicker on LED screens.
Does the job very nicely,

Regards.
Is it possible to keep SGS2 brightness at max and then use this app on top to make it appear darker? Or is Screen Filter just a replacement for the SGS2 brightness control that allows further dimming than minimum, or does it work differently?
Thanks
I havent noticed flicker on the S2's screen on normal usage unless I open up specific test patterns for flickering like this site
http://www.techmind.org/lcd/
It of course is to dimming it over min brightness for easier night reading without any sort of strain, haven't used with Max brightness as even 25% is too bright for me for normal usage and then that app with Auto brightness for night readings/browsing
Regards.

Oh. I thought maybe it worked differently since on the app description it talks about applying a "shade" over the screen.
It might work for me if it did not actually dim the LED, but "filtered" the information to be displayed so that it came out less bright. I don't know how exactly that would work, and I guess if this "software" dimming was available then manufacturers would already be using it.
I've decided to go with the HTC Sensation. I figure that the SGS2 will either be the worst or the best phone in regards to eye strain, and it's not worth the risk. Kind of bummed out since I had my heart set on the SGS2 but hey everyone keeps saying that they're both great phones.
Both phone are great but i dont seem to experience eye strain on sgs2 seems good to me...imho
Hope posting here does not violate any of XDA forums rules.
I have an idea for a while and I need your opinion about it, and therefore if anyone wants to help...
There are too many apps, solutions etc. for power saving. However, most of them create a bigger consumption problem or limit the phone experience. We also know that about 20-40% is consumed by screen brightness, especially when it is above 30%. Auto-brighness is a solution but not the optimum because in many cases it is not the desired one. Not to mention that many devs state that auto-brightness should be avoided because it could be power-consuming as well. Finally, it becomes obvious from the battery menu in settings that the line declines sharply when we have the screen turned on for a LOT OF TIME. Cpu processing does not even seem to consume as much as the screen (when not processing in full).
So, noticing that the screen can become power hungry in relation to how much time it is turned of, then the variable that adjusts the brightness could be the time.
What I mean: Most of our essential actions, like reading a message, make a call, change a song or even search something in internet take about 30 seconds to 2-3 minutes and require a relatively high brightness at any case. Other actions such as internet browsing, gaming, reading etc take more than 4 minutes up to 20 or what ever.
So, I was thinking to apply a minimum and a maximum limit in brightness. For the first actions like reading a message the brightness can start at the higher limit and stay there for as long as this short-time action takes place. For the second group of actions the brightness could start from the higher limit and after 3 or 4 minutes the brightness to start decrease at why not an exponential rate until it reaches it lower limit.
Advantages:
1)You set high and low limits so you are never dissatisfied with what the device gives you
2)Not quick and sudden brightness chances as it happens in auto-brightness.
3)Always high brightness for short-term actions
4)Great energy saving from long-term actions, like gaming
What do you thing? Is it worth give it a try? i would have tried it but I do not know how to make a script for it. Also many ideas for it and mods that I can share if you think it is worth spending some time.
Sounds alright, but the deal breaker for me would be seeing the screen slowly get darker before my eyes..

Exactly, that's the point. For example during the 2 first minutes the brightness to stay as high as the upper limit and then after the two minutes to start GRADUALLY getting darker up to the lower limit. So you can start at 80% which is pretty convenient to check the time outdoors with sun and then if you browse in internet it can start gradually getting darker until it reaches the 65%. If you could see the graph the area is significant amount of energy. If only I could make a script I would try it or at least make t happen for myself....

Well because i froze a ton of samsung and att bloatware and ive seen no improvement on my weak short battery life. I mean 4:30 hrs on battery with 3:01 screen on and im at 15%.... maybe the system is looking for the disabled apps??? I dont know..

3 hours of on screen is why your battery drained. Doubtful it's removing system apps.

I've seen really varied battery life. The screen is the number one battery drain on our phones so I use my brightness as low as I can get away with. Monitor your battery life day to day and see if screen percent battery usage even when used for 3-5 hours should start to show closer to show 20-30% of your battery usage vs the likely 50% or higher you may be seeing now. I use a third party app to lower brightness even below our normal GS3 brightness when I know I'll be surfing or using the phone an extended period of time.
Common battery conservation knowledge consists of simple things like disabling GPS, WiFi, and Bluetooth when possible. Limit or turn off sync when uneeded. Turn off led lit touch buttons if you get used to menu and back where they are. Turn off sprint network optimizer (sprint only) it seems to scan networks too often leading to too much battery discharge for me. Turn location services off if not used often certain ones not GPS effect battery too. Uninstall bloat which you did. Turn options in apps off not to sink.
Check battery usage during screen off and idle and make sure your phone is sleeping. If you have a sleep bug the phone is not shutting down cores and lowering speed while not used leading to multiple hours of battery life lost. I turn off vibrate and haptic feedback off except where I can. If your rooted take control of your cpu and when not needed clock it down yourself. If your browsing you may not need max frequency. 1ghz core or less is good to save power while just casually using the phone.
Just a rant on what I've had success with. No pic but I have had success getting 24 hours between charge with heavy use like 6+ hours screen on if I was really conservative. Most days of heavy use as long as I didn't use a giant overclock I get 9-10 hours between charge.

My favorite brightness widget for quick access and free on play store.
https:// play.google. com/store/apps/details?id=com.haxor
The great widget that's free on play store to adjust your brightness lower than current device brightness in a percent form. it can go 0-100% below your lowest brightness level or even below your highest brightness level if you prefer... as its based on your current set device brightness and is accomplished by using a screen overlay I believe. Adds a little lag when enabled but saves you the power when needed.
Remove extra space in address for Play store links. Admins hope link okay.

I might just check this out as well. The built in SGS3 brightness thingy is garbage so I have it set on max *I still get 4hours of screen on for max brightness tho haha*
Edit: Those apps are not what I thought they are.. I thought it was a different auto brightness thingy but its not that still useful I guess if you want to go crazy on battery.
3 hours screen on = good

Okay thank you kindly. I know much less than anyone here. I am new to this world and new to Android.
Those apps are not new brightness control as you have stated. ofirst one is a simple widget to change brightness from home screen so its just a shortcut. The second a screen overlay that doesn't get in the way of using apps and darkens the screen beyond minimum brightness that SG3 or any phone has. If a user does not need lower screen brightness than normal than the above apps are not going to be useful. Thank you for fixing links. I hope I can add to threads and around.
Like you I would love to see an app that creates a custom auto brIghtness function.

Thanks this looks great. that's what I was looking for in first place. Ill give it a try. That's definitely better yet.
A guy commented on app there and said useful info as follows which Ill try out myself just thought it was also interesting.
"On "automatic dynamic" mode- behaves buggy & erratic. USE: "automatic periodic" with updating at 5 sec intervals. Now works well. Set backlight zero to 10. Sample lux/% settings: 10/-55%, 100/10%, 500/35%, max/100%. Try it. Be nice if widget also showed Auto & %." -Heath
Edit: After trying the above app it easily replaces both apps I posted. Thanks jmorton10 for posting this great app.
Edit: After using all the apps. I found Lux can create lag in the touch interface and browsing etc just like the app"Screen Filter" I posted. On screen filter it causes lag when enabled and for some reason Lux also does this to my phone. Once I disabled and restarted the lag was gone again. I don't have to restart phone for Screen Filter just turning it off with a single button press fixes it. Lux has more features and actually makes a custom auto brightness profile. The free version is fairly limited but has enough to still make a fair brightness profile. Given the lag which is likely on just a few handsets is something most of us saving battery can deal with. Between all the apps I guess it depends on what you need. Lux is a top notch software but the free version is fairly limited vs the free brightness widget and screen filter but has no auto-brightness customization. The lag on Lux was not right away and was exactly like the lag in screen filter app so both must have issue in way the below normal brightness is overlayed over the screen. The paid version is likely very in depth.
Thanks for the app suggestion again.
Thanks for the input. I bought the onite 3800 mah extended battery, but im changing it for the qcell, or hyperion.

If you have an Amaze then you know that the secret to long battery life is minimizing screen brightness. Problem is the default auto-brightness levels are brighter than needed and there is no way to adjust.
I recently installed Lux which allows you to customize the auto brightness curve. This should theoretically extend battery life. I'll report what I find here on this thread.
Meanwhile one thing I noticed.... In Lux you can monitor the level reported by the phones built in light sensor. On my Amaze I get really strange readings. There are four levels: 90, 320, 640, 11000. Really? With careful shading of the sensor I was able to get a reading of 2400 once. 11000 was reported even in shade on a cloudy day.
But it seems like the sensor doesn't read light levels well at all. There isn't enough granularity and the calibration is way off.
Anyway if we can fix it or address it, that should make a real difference in the battery life of the device.

This one is pretty awesome.. "Display Brightness".. https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&hl=en
You can put a 'slider' anywhere you want and simply slide it up and down to change the brightness to the exact levels you want.
Works great an you can customize it quite a bit. :good:
It's shown in on the top in the screenshots at the link, but I always put it on the right hand side, a little higher than mid-way, and I make it translucent grey so you cant even really see it unless you're looking for it.
That's the free version, I have the Pro version and it's worth it. lol
Anyone else having problems with automatic brightness changes?
Every evening when it gets dark the brightness level goes to the lowest level, which is much to dark to read anything. Every evening I have to adjust the ''automatic'' level to halfway the level-slider, multiple times.
Do you have night mode enabled ?
I have this feature enabled from 9pm to 7am and indeed the auto brightness goes lower than normal value during this time slot .

The same is happening to me. The brightness of the screen in darker lights is too low. Every time I move the slider to upper brightness but next time I open the screen is lower again.

I might state the obvious, but the sensor is a bit high up on the device and it might be covered by your phone case, u sure it's not just a goof with an off brand cover?
The sensor is not covered. I use an original OnePlus cover.
Strange thing ... Everybody or at least majority of Oneplus Nord 2 owners had complained about automatic brightness . It's true in my case as well but now problem is solved with a 3-d party apk . Velis Auto Brightness from G.Play . Calibrating autobrightness is very accurate but the app remain active in background all the time and I didn't know how this affect battery drain . I read all OnePlus latest phones have this annoying bug and it's pitty none of latest updates solved it , worst here on XDA or OnePlus forum no one offer any solutions to calibrate automatic brightness .
Some smart guys said there is not "automatic brightness" but "adaptive brightness" so we had to learn phone AI how to adjust brightness a few days and then restart the phone . This are childish thoughts of those which are nothing to do else .
So , what do you think about this ? There are solutions to calibrate or fix this issue ?
I noticed that when the phone is on below 15% or lower and the battery saver is on ( for me it's 10%) the phone brightness goes to automatic mode and it becomes even less bright. I think it has to be a certain feature which is connected to battery saving IMO.
I'm using Velis for 3 months as well. This solves the problem. But OnePlus definitely should solve this.
Even latest update v11.3 EU, doesn't solve it. I even did a factory reset. 3 hours work to reset everything back as is was, for nothing...
Look at a possible solution (for me didn't work) :

FYI: I did this a few minutes ago. I think that may be it. Before I did this, the screen brightness did not work at all. I could slide that slider up and down and nothing ever changed on screen brightness, auto or manual. Now it works! On auto and manual!
Hopefully this is the "fix"! But disabling a feature is NOT a fix, it's a workaround. Luckily I don't need that feature

So far the screen brightness has not faded into darkness. Phone is working fine now. This is a workaround that works.

Minimum level (especially in low light) is a little bit higher , sensitivity is more accurate and transition between levels is also a little bit faster . I'm pretty sure there are some improvements , that's a fact not a feeling .
