I've searched for an answer to this but I can't seem to find anything. When my GSII gets below 15% or 10% (can't remember which) it starts locking out functions like the ability to take pictures or video, and most annoying adjust screen brightness. I know this has been a problem on other devices, but does anyone have a fix or an idea of a fix for the GSII?
I'd much rather have the control to do what I want with my device than be forced to this power saving mode...which seems insane considering there is already a settings menu for a power saver mode.
I've heard this is fixed in the KE7 firmware upgrade. Not sure though
I had a topic abouth this too. It is just REALLY stupid!!!
You can say you only have 85 % of battery life, because after that, you are not in control of your phone...
If I want to watch browser info on the highest brightness with my last 15% i think I should be able too... And if I want to take a picture with the same 15% that should be possible too.
This is so stupid, does Samsung think we are kids?? If I want to save battery for something else, i will use power save mode.

Go to the VRTweaks thread in dev forum
I've got an app that lets you replace these stupid restrictions in apps with my modded versions that don't do this.
As a bonus, you can listen to music while using camera too

I'm liking what you've done so far, but it's really the removal of brightness control that's getting to me, and it doesn't look like you've approached that problem yet. I'm fairly ignorant - do you know if that's something that can be dealt with through the sorts of tweaks you're doing or is it something more complicated?

Hmmm... I thought your issue was the low battery and using the camera?
Anyway, I can look at the brightness issue, if you can let me know what appears when it happens?
It seems to me that you CAN control these settings from the power saving menu? Is that not correct?

The biggest thing for me is not being able to control screen brightness once the phone decides it's battery is low, and to a lesser extent taking photos (it will play videos at any battery level though, which looked like one of the issues you fixed with your tweaks oddly enough).
I can't remember if it's 10% or 15% remaining, but at one of those points the phone warns of low battery and automatically dims the screen to 0%, among other changes. The brightness can sometimes be forced back up, but it's only temporary, reseting itself after a few seconds or after a screen lock. The power saving menu I don't understand the purpose of at all, because I have that turned off and these things still happen. If I turn it on and set the screen brightness to a higher level, it does what I mentioned above. It's as if there are 2 power saving modes that aren't cooperating.
Is that clearer?
Hi guys just wanted to say my galaxy s2 is officially busted. Its still in working order do not get me wrong but something wrong with the hardware i think because i have flashed so many roms and stock roms to try and resolve the problem and i cant. My display is always sky high in battery usage and i cant get it down to save the life of it. Got everything on the lowest that is brightness settings and still nothing. Spoken to samsung and they say its not suppose to be like that and that display always high and as high as 60% is not right.
What can i do please cause i love the phone and it really pisses me off that it gets drained so bloody quickly? Shall i just sell it and get an HTC sensation instead or shall i send it to Samsung and be patient for ten days without my phone

Id say just wait for the new phone, the galaxy s II obliterates the Sensation. This coming from a person who's owned both devices.
About your display problem, sounds pretty weird never heard of an issue like that before.

What is your average display "Time on" on "Battery usage" when you're almost running out of battery?
How quickly does it drain? Don't you have warranty to get it replaced if it's actually faulty? I can't really decide if that's the case from your non-sense post.

My display is high as well with android Os in second most of the time and its normal, cause I use the phone a lot so obviously the screen will be high.
I get around 13-17 hours heavy usage so am happy I dont think its anything to do with rom flashing unless you get lower then 10 hours battery life
sorry i should of made it more clearer. Once i charge my handset as soon as i start using it you can see the percentage drop rapidily. i go into the battery usage and the display is at its highest and draining the battery. And that is with brightness to low settings. If i do not use the phone it can last me for a whole day and a half. But im to scared to use it for browsing and thats over wifi cause i know it will not last me to long...i know the handset is a battery drainer but come on the display should not be as high as it is..and with the warranty i have put the stock rom back so can they find out still that i had my handset rooted if i was to send it in

If you get two hours with screen on, than that's normal and not a hardware failure. Use white backgrounds as little as possible.
Apparently they could, I believe they some kind of count record of the amount of roms you have flashed and the only way to reset is by using a 'JIG' if you search the forums should be able to find more info on the 'JIG'

Looks like SAMOLED+ consume most power on SGS2. I thought it's normal. Just know mine also having the same problem.
Sucks to be the guy who receives all these problems. I suggest, you just get a refund, as you should be ashamed of yourself if you sell a defective SGS2.
If you like the sensation, get it. It's also good, as I usually borrow it from my sister when we feel like exchanging phones for a few days. Sensation's default battery life is a little worse than the SGS2, as I only get 18hrs-1d 4hrs in the Sensation(still not rooted/default ROM) against the 1d - 1d 10hrs of the SGS2(Leomar ROM + Ninphe 2.2/undervolted).
My sister just got those chichitec 1900mAh batteries, and she said battery life on the Sensation improved(Only her word, as we have yet to exchange phones again this weekend). Now, all it needs is an undervolt + good ROM and the Sensation's battery should last a longer if not the same than the SGS2. Though you'll surely miss the SAmoled+ quality if you compare it with the SLCD of the Sensation, hope HTC improve on this department, they should have used IPS instead of SLCD.
A little tip if your getting the Sensation, is to thoroughly check its touchscreen sensitivity. My Sensation, is a little buggy sometimes, sense lagging/resetting + weird touch sensitivity. Though, I think it should be fix by flashing a good ROM + Kernel. Good Luck.

what is your display percentage and how can you manage to get so many hours out of it? any tips? i will be posting screen shots tomorrow for you guys to see what im talking about
If you have been using the phone the screen will always be #1 on the list, as its the part that needs the most power.
The phone will get about 6-8h of screen on time total before the battery is flat, but it will depends on mobile coverage (weak coverage will drain faster), if you are using heavy data, wifi usage (will be better than using mobile data on a weak signal or if you are pushing a lot of data round).
Generally radios will eat up the juice.
Also games will hurt.
You can use CPUspy to see what states the CPU is in, and if its going to deep sleep.
Also in settings > about phone > battery use, you want the awake and screen on lines to match up as much as you can.
(Music will keep the phone awake while the screen is off, and so will downloading stuff etc)

The truth is, that what you report as a problem, is not a problem, it is simply a fact. SAMOLED displays drain batteries like hell. Mine does exactly the same. Like you, I was starting to think that my unit was somewhat faulty, but soon fund out that it was not. In fact, the truth is that the galaxy s2, if left on with the acreen at normal brghtness, fully drains its battery in a matter of 5 hours or so. It is due mainly to the display draining something like 0.8 Watts, alone.
People saying they get almost 2 days use simply tell bullocks, because there's no way of actually using this phone and getting more than about 15 hours autonomy from its battery.

Samsung support/RMA process has worked very well for me. Third phone already. Maybe ask them to replace yours?
I'm still confused over there. You're just talking without making any sense at all. The only thing I've got from all this is that you're complaining about display being the highest on the battery drain list. That means nothing. Or not much at least. Those values need to give a total of 100%, so if you're using your phone, and display is the highest, your phone is working really good, and you don't have the AOS bug. Which means your device is not faulty, you just don't understand the battery statistics screen. Pardon me if I understood your problem wrong, but if I didn't, just carry on with your life, your phone has no problems at all. I get around 1.5 days with medium usage, and I think that's normal for a phone like this.

You are not being rude at all. I have flashed yesterday batistas new rom and using jeffrey speedfrey kernel and i have fully charged the phone and calibrated it as well. I am going to let it die down and recharge it again to the max and see how it goes after that as well. My point of this though is as below on the screenshot. The display is always in that percentage and that is what has me worried. I have checked on other posts and the most that they get is 35 to 50%. I have the lowest brightness settings and it still that high..That is why i am asking if there is something wrong with my phone. I am getting good battery life so far just with medium usage and having wifi on since i have charged it but the display is what worries me. If someone could help me with these pointers as well i would appreciate it:
Does underclocking with Setcpu help battery life even more?
And what do you guys think of the screenshot?
i know this sounds silly but how does someone close a thread once they opened it i have a few i want to close..
Thanks again to everyone for you help..
It has dropped to 76% after 10 hours and a couple hours of screen usage. I don't think that there is a problem.

Hi there fellas using s3 like me its been 2days since i've bought this beast and i really wanted to know if using smart stay and keeping bln on does affect the battery much or not, as i couldn't come up to the conclusion yet. So what do you guys think who have owned this phone for some time now??
Smart stay affects battery consumption.
Well it affects battery file but not to the point that it drains the battery. Plus its a very useful feature
Some, but negligible affect on overall battery life.
Sent from my GT-I9300T using xda premium
whats "bln"?
Back Light Notification a thing of the past with S3... think op is thinking of notification led...
I guess i'll have to agree with you guys because i kept it on for a day and off the other, there wasn't any noticable difference
Yes and no, if you constants get text messages / notifications then the BLN might have an effect on battery, same as if you stare at the screen for a long time the Smart stay might have an effect but in general compared to other apps,etc i wouldn't think it's what one would deem to be a big problem.
It's hard to tell since I've only had the phone since for 2 days and have been using it constantly, but I think it may be a light load on the battery. I had one instance already where it think it was wake-locking the phone. (seen using betterbatterystats)
I will report back later after I have investigated a little further. It may not even be worth it to me...I'm pretty well trained in turning off my screen immediately after I use it, I don't let it time out on its own.
OK here is the official SGS2 I777 Battery saving thread. I don't mean to be a culprit and post "another battery saving thread", but I am. So get over it. This thread is meant to maintain the battery savings threads, all in one place. INCLUDING: Battery savings tips, philosophies, and other methods of efficiently managing the charge that your battery witholds. Since I searched through basically all of the 17 pages in both the I777 and regular SG2 to collect all this. NOTE: THIS THREAD IS NOT MEANT TO ADDRESS BATTERY DRAIN PROBLEMS OR ANYTHING OF THE LIKE. DO NOT POST YOUR PROBLEMS HERE. This is simply a collection of what I found to be the most essential threads and information regarding efficient use of battery charge and battery savings. I'll update this every few months, or as I see fit. I don't see things changing much since the way a battery works, and our android os will be relatively similar over the years.
I realize that people looking for this information could just go through all the threads like any other xda troll would be the first to point out, but I also recognize the noob community for this phone (I was once there myself) and would like to be helpful in providing it all in one place to prevent others from wasting their time, whether deserving or not

THE TWO THINGS THAT KILL YOUR BATTERY THE MOST:
Super AMOLED Screen: Now it's all apparent to us at this point that android screens (S-amoled's) kill very large amounts of battery. You will save copious amounts of battery if you do not use your screen as much, hence why half of the people posting their battery stats have screen on like once an hour for half a second. They basically don't use their phones.
Data/Radio: Ever notice that when you put your phone on airplane mode before you go to bed, when you wake up it's only gone down by about 1%? That's because you're not getting any service, and have no data coming in. Believe it or not, the phones hardware is pretty efficient. CPU's don't use very much idle power at all, and I expect that to stay the same, even with quad-core processors coming out. It's mostly the over air things (and screen ) that kill our battery. Data itself uses a **** ton of battery. On a daily basis (And I've tried just about all the roms; CM7,CM9, MIUI (GB and ICS), SammyTW ones, etc.) I use a considerable amount of data. I try to have my data on most of the day since I get facebook notifiations and send/receive MMS's, but on the days where I have it off for a couple hours I start to notice, damn, my battery is still pretty high
EDIT: Using Edge/2G saves a lot of battery if you're someone who needs data on most of the day. I recently switched to instead of intermitedly turning data on and off, just having Edge on all day (for notifications) and then switching to 3G when I needed to browse or use maps, etc. Idle usage of Edge vs. 3G is probably around 40% less battery consumption (my opinion), it works really well for me.
PHILOSOPHIES:
If you want to compare your own battery life with others to get a better idea about things, check out this thread:

Juice Defender + others: I am a fan of this application. I used to use it for the first couple months I had the phone and it made a significant difference (mostly because of data deactivation). It makes 20-35% difference in savings from having not micro-managed anything yourself to then using the app. There are other variations of JD, GreenPower, Battery Booster, etc.

Underclocking and Overclocking: These are ways of tweaking your CPU usage. Underclocking is known for when you limit the maximum frequency, your CPU can clock to. So in laymans terms, what that transaltes to is your 1.2 GHz (1200 MHz) processor, can be changed to a 0.8 GHz (800 MHz) processor, if you were to underclock it to 800 Mhz. This is helpful to some almost completely dependant on your usage.
More elaborate, drawn out explanation: While your phone is idling, or sitting with the screen off, it is sitting at 200 MHz (lowest default - if you go lower than that your phone can become unstable [screen not turn on, etc.]), so underclocking won't help you improve battery usage much if you just keep your phone off most of the day. Undervolting would help more with that. if you however, find that you play lots of games, or mindless swipe across homescreens all day confused, or perhaps photo editing apps, or other things that use the maximum cpu frequency; then you will find that having your phone underclocked to 800 MHz, forces your cpu to work less during those heavy maintence situations, but in turn, prevents heavy battery drain. What this translates to in daily use: If you play angry birds, your phone's cpu might be jumping up to 1200 MHz (depends on your kernel settings - usually it's set to ondemand, in which case it will do so) during those swipes when the bird flys across the screen. However, that is not a very cpu intensive action, so if you were underclocked to 800 MHz, you probably wouldn't see any difference (lag, stutters) in your game play. However, if you were playing a 3D defense game, or esentially any other 3D game which requires you to scroll around the map, or has many many things on the screen at once (beyond fruit ninja and angry birds), then you would notice a difference in performance due to underclocking. I mention all of this because underclocking will be most effective during those situations, but it can also be the most hindering, in those same situations. All depends on how you're using your phone and what you're trying to achieve, while maintaining a certain level of quality.
Overclocking works the opposite, if you are trying to reach a certain level of performance (you just downloaded a new 3D MMO dungeon defense game and your phone is jittering and laggy during gameplay), beyond your default 200-1200 MHz clocked cpu, you may overclock up to 1600 MHz (some devs don't like you doing it - because it is essentially quite harmful for your cpu if used for a longer period of time), also depending on the kernel (again, devs created them) you may not be able to overclock, but on the majority you can.
To Underclock you will need an app called SetCpu (or equivalent) in order to change your over-underclock rate, as well as the scaling of your kernel (ondemand, performance [max frequency, all the time], conservative, etc.), also some roms have clocking options built in (such as AOKP).

AMOLEDs are supposed to be more energy efficient than LCDs I thought. That being said, I think one problem might be that many users of the former tend to keep their screens very bright because they are such a beauty to look at. I get what I think is good battery life by adjusting the brightness of my screen down when on battery only and by fine-tuning auto brightness settings.
One of the nice things about the S-AMOLED screen is that when it shows blacks, it's not using pixels. Pixels are actually turned off for the blacks. You can get further battery saving by using darker themes and inverted apps. Of course, that's not to everyone's liking. Me, I tend to like darker, tending towards minimalist screens as opposed to bright, busy ones, so it's a win for me.

First, in reading my paragraph I was speaking of JD's helpfulness in relation to not micro-managing (turning off data, etc.) anything yourself. In this case JD helps a lot....
Second, I didn't bash any part of our AMOLED screens, but they use a lot of battery...idk anything about how they compare to other screens, and idc...that has nothing to do with my post. We all have I777's, and that's the way it is, so I'm not too concerned of other screens.
I will say, that in light of reading most of your comments (which are found everywhere) , evidently, that you do at least make a good point, most of the time.

Yes data drains battery. If you are rooted (I hope you are since you are reading this on xda), you should get Droidwall. It's a firewall for your phone which limits certain apps to use network data, wifi data, or neither. Useful if you are also a little bit paranoid :silly:.
Another amazing app I also use is called llama. It is similar to tasker but it's free. This app allows me to set profiles and actions based on location (antenna mast instead of GPS to save battery) and other triggers. Not sure how ICS manages BT and Wifi scanning but those things use to drain my battery under GB so I got into a habit of toggling them on/off. Llama can do it automatically for me because I am lazy or sometimes I forget to.
I think any phone screen can be a big battery drainer if left on long and are set really bright. I have a habit of hitting the power button after I am done using it as opposed to just letting it shut off by itself.

They are more efficient than LCD's, and I made no notion to say they weren't. I simply said that they were one of the two main culprits of battery drain. I'm not saying our phones suck cus they have AMOLED screens, it's actually awesome. I'm just saying, like any other phone, having the screen on lot is going to kill your battery.
Yeah on stock (rooted after a month) I used to use auto-brightness most of the time, and sammy's auto seems a little brighter than necessary by default (so I'd keep it on 40% some days). But after switching around to different rooms (before I started tweaking auto-brightness) having brightness at what I'd actually consider an adequate level, versus a little bit brighter makes a huge difference. When the screen looks just a little too dull in all situations it really takes away from the experience hah
Also, I know black pixels are technically off on AMOLEDS, but I've noticed on many occasion when using in a room with no light on at night (pitch black, essentially) that when rebooting and hitting the yellow triangle screen (mostly black) you can see the black area of the screen. It's not completely black. It's definitely a very real looking black, but it still looks like there's a backlight behind the screen. Is that the case? Can anyone confirm?

. . .idk anything about how they compare to other screens, and idc...that has nothing to do with my post.

While it may not have anything to do with your post, per se, I think it's a good idea for people to be educated about our screens since many *are* coming from the LCD world and some of the rules they're used to don't apply. And some of those rules very definitely have an effect on battery life, like the rendering of blacks that I mentioned above.

They are more efficient than LCD's, and I made no notion to say they weren't. I simply said that they were one of the two main culprits of battery drain. I'm not saying our phones suck cus they have AMOLED screens, it's actually awesome. I'm just saying, like any other phone, having the screen on lot is going to kill your battery.
Yeah on stock (rooted after a month) I used to use auto-brightness most of the time, and sammy's auto seems a little brighter than necessary by default (so I'd keep it on 40% some days).

That is the case with LED screens. In a mostly black scene, the individual pixels for the black area are not lit, however there is still a backlight lighting the screen itself which you may see bleed through. This is of course assuming the phone LED works at least somewhat similarly to a TV.

Yes I agree with you on that. It is more the manner of criticism which he spoke it that I am not favorable of, not necessarily the information which he shared. Which is why I wrote what I did at the end of my comment.

Ahem....let me try to get his thread back on track.
I agree wih your comments vanillacracker. On a gb rom if I disable auto sync it helps me a lot wih battery life because he signal is really awful at my work. So I guess if the signal is bad it tries to sync amd keeps doing it for a long time whih really drains the battery. Disabling background data helps even more but I like to get my emails so I do not.
Sammy based roms are the best wih auto brightness quickness. Aosp roms are always slow to react. I hate when I step outside and the screen takes for ever to adjust. But the sammy based roms also have high default brightness as you mentioned.
Ps: do not feed the trolls. Just report them.

I will agree with you on most of your points and yes you are correct about the signal, the worse your signal is the more it affects the battery. Also, tasks aokp has the option now to change the reaction speed so if you like aosp but hate the reaction speed that is an option.
How exactly was I trolling? I know you're referring to me, I made a criticism of two points out of the entire thing and he tells me I'm a troll and that I need to take an anti depressant. What exactly did I do wrong?

Ohh alright that makes a lot of sense then. Thanks a lot, that was really helpful for me! Yeah cus in the completely black screen sometimes I can see the little splotches that look like it's where the backlight is squished against the screen or something. I noticed the marks are in a different spot on my current I777 than they were on my old one (replaced cus power button stopped working). Yeah it would make sense that AMOLED's came around the same time LED's started getting more popular in TVs too (few years ago), pretty baller technology for a phone! I'm loving it haha

Way to come back with a personal attack, it's been proven in many cases that JD does not help and if anything hurts battery life. I used to use it and now I don't with no hit on battery. I'm not depressed thank you very much. I reported you for that one. I wasn't saying anything bad or personal but you had to go ahead and do it.

I disagree with you that Juice defender does not improve battery life. I am aware that obviously running an app in the background (Juice defender in this case) uses battery. But if the app is disabling your data (data uses battery..more than the juice defender app uses) then it's not possible for it to not increase battery.....just logic there. Anyway I'm sure there's been reports that say it does and does not increase battery, it's been obvious to me that it does, and it's logical to assume it does (if you know what I'm addressing) too. So I'll say to each their own. I do not wish to argue about things anymore, I will not edit my thread to your liking, you may simply dismiss that tip if you'd like.
I do not care about a report, I'm sure most people see the way I act and understand my reasoning. I probably overreacted a bit to your initial response , I've edited my accords. :cyclops:
BTW, VC, thanks for the compilation. Hopefully it will prove useful to folks!

Dude.....no offense but your first post was pretty disrespectful....hence my comment. However your quoted post was very useful. I believe in one thing...you give respect you get respect.
Now...getting back to the topic....good point about tasks rom....I did try it out but frankly speaking it is still not at par with sammy base roms wih regards to auto brightness. It does rock otherwise.
I am currently on ktoonsezs MIUI port (love that guy. No homo)....and m pretty happy with the auto brightness

If the only thing which is holding you from using aokp is the auto brightness, there is a flashable zip in the fluxxi thread which gives great settings.

OLED screens do not have a backlight. That is one of the things that make them much more power efficient than LCD. The pixels themselves in an OLED display generate light.
Does removing bloatware drain battery?

No.. helps battery life just freeze your the boat in your app settings.

disabling bloat helps keep less apps using cpu resources therefore less battery drain be careful on wat u freeze though

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..
Sent from my SAMSUNG-SGH-I747 using xda premium
3 hours of on screen is why your battery drained. Doubtful it's removing system apps.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
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.

Fixed the links for you. Once you get 10 post you can link don't just spam for post tho.. at least attempt to add to the thread when you do those 5 other post.
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.
