What exactly manages in the power saving mode ?
what is the analyzing image ?
I wonder the same thing :/...
I unchecked it.
Also wondering about this, anyone care to enlighten us ?
umm this would be a guess, but I'd imagine, that due to the fact AMoled's use more power when showing a white images, is there a chance this setting uses some kind of algorithm to see how much of the screen is white and adjusts the birghtmess or colour to reduce the strain on the battery.
So if you are showing a white background it would tweak the brightness down a little, or maybe even depending on the colour, if some colours use more neegry than others, it might throttle them back slightly to conserve battery.

Yea i have no clue what this thing does. I'd also like to know though.
I'm almost affraid it'll consume more battery, don't know why.

Is there a software for making the flashlite turn on without using the camERA ON.
It is really useful if you dont want the camera to drain the precious battery... especially if you need it for hours...
I dont remember it, but I think I've seen it before somewhere in the net...

Well, when using the camera app, it's not the sensor itself, but the maxed out backlight and the flashlight LED that eat most of the battery. So turning on just the LED won't buy you too much battery life in my opinion. Besides, i don't know if using a wizard as a flashlight "for hours" is a good idea - that thing is a high power LED, and they tend to heat up during prolonged use. Since it doesn't have any heatsink or even a big PCB to help dissipate the heat, it wold probably get damaged after half an hour of using it at max brightness. It would probably last longer at lower brightness - like when the camera app is turned on (the camera app enables full brightness only for a second when taking a picture), but using it for long periods of time even in that mode isn't a very good idea.
I think you'll be better off buying one of those small keychain LED flashlights, of a bit bigger flashlight using a 1W power LED if you need something brighter. It will be much cheaper than replacing a burned down LED in the phone.
And for short term emergency use - starting the camera app isn't that much of a problem after all.
Using your flash as a flashlight is a surefire way to burn it out. It's a high output LED, and isn't made to be run constantly. You can definitely do this trick, Vijay555 has created a widget that lets you toggle it on and off, but even he warns you of the consequences.

But it's not possible to dim it with this app, the camera program dimms the LED until you actually make a picture.

Actually the flash led is bright but the backlight maxed out with a white screen puts out more light. It still runs down the battery quickly but you are not pushing anything the phone isn't designed to do. I created a mortscript that combines two apps I found on these forums. One maxes out the backlight and the other displays a solid white screen. You can pick other colors too. here is the link http://forum.xda-developers.com/show...4&postcount=24 I use it all the time when I'm under a desk plugging cables into a computer and need a light.

THATS VERY TRUE BUT IM NOT GOING TO USE IT FOR A HALF HOUR!...
its just that i want to show of my phone to other people...
and probably use it at night or so
thxks for the link..!
I wonder if somebody can give a solution of automatic backlight adjusting.
I think as a phone Athena need to be bright enough to use outdoor as well as in house. But it is a pity that the screen looks poor outdoor if the environment is already light.
My idea is to check the brightness via its built-in camera and adjust the backlight setting automatically. But it is again a pity that I am not able to develop on WM...
Can anybody give a solution? I would appreciate very much!!!
I have this feature on my Dell D620 notebook (dim sensor) and can tell, it's not significantly useful - at least I can see no difference, since the display itself is too dark for regular outdoor use.
Regarding your solution: I think the permanent camera-use would consume quite some power, wouldn't it? So the costs would be a faster leeching of the battery while the benefits are to automate a rather simple backlight-slider changing...
Any good? Camera+program vs. eye+hand?

Hello will_990,
I totally disagree with you. Form view points of benfit and battery.
I agree with you that the display itself is too dark. It is dark even if I manually turn it to max when I stay in sunlight. But won't software help a little bit? For me at least this will enable me to dail. Then the question is how to make a dail faster.
I do not see any clue it will drain larger power. If I move from a light place to a dark place, then the reduced backlight can then save some power. In addition, the camera does not have to stay on and keep acquiring brightness all the time. The use case could be:
1. User activate on screen.
2. Due to the event camera is on and light is acquired.
3. Software caculate brightness and suitable backlight.
4. The program set backlight and switch off the camera.
You have to check if a while of camera-on consumes more or lighting backlight high does. Assume that P1 is camera power and P2 is backlight power. t1 is calculation time and t3 is manual adjust delay. t2 is the duration you use it then. I expect
(P1+P2)*t1<(P2-P2')*t2.
Certainly, you can use your finger energy to adjust and thus save battery. Then P1=0 but P2*t3 is existing yet. Especially, in case you hold a device already dark, you have difficulty to find the slider so t3 becomes a consuming factor. I expect optimally even
(P1+P2)*t1<P2*t3.
I still looking for solutions...
Your opinion is well founded, however, in my opinion it is lacking at a certain point: I simply don't think that (P1+P2)*t1<P2*t3 could ever become true, unless you'd spend a really long time in changing the slider - or calculation time (and therefor CPU power consumption) would be set rather low...
I have to admit, though, that I don't know the variables' true values, therefor I can't verify or falsify your equations.
Anyway, it would certainly be interesting to test it, google is somewhat lacking on this topic.
Suppose a Case
The later equation deduces to
P1/P2 < t3/t1 - 1.
The battery is 2200mAh. I assume it lasts 3 hours with simple taping operation. So I suppose then 733mA is drawing normally without camera. Suppose the camera(the upper camera) boost the current double, addition 733mA, and calculation time is 10 seconds, and if you spend more than 20 seconds on handling the setting, you make it true.
Nevertheless I have to say, the number is just my estimation.
Even if the later one is false the feature is still attractive.
Looking for somebody to go on with this idea...
Could anybody to go on with this idea?
Well, when battery going to die on the G1, the light flashes red. Which all it does is take up the little battery you have left. Any way to turn it off or an app that maybe can?

That LED takes up very little battery power if any. Trust me, if you're that low on battery power, then you have more issues to worry about than an led being on. That thing probably draws like 1/10 of a watt.
Aside from whatever power it draws, I'd like to be able to turn off the low power light because it overrides other notification lights. It doesn't let me know anything aside from the fact that the power is low.. It'd be nice if they could rotate or something.

Now that makes more sense as I have had the issue as well when I charge my phone while sleeping.
I asked the dev of Missed Call awhile ago if you could change the color of the charging and low battery. He said he couldn't because there is no change in something, I think no change in the HEX code or whatever.
Maybe he could try again, I would ask him since he was able to change the colors for everything else.

I really like the auto brightness feature, but it's consistently too bright for my taste.
Is there a mod or tweak out there that will allow me to lower/adjust my automatic brightness levels to save some battery life?
(Currently running Blackhole 3.0 / DL09, will go to Blackhole 4.0 once it's out tomorrow)
anybody have any ideas
Unless you know how to modify the kernel source (which I believe is written in C, correct me if I'm wrong devs) or modify some file that is the delegate for the ambient light sensor, you're SOL buddy.
Its probably hardwired into the kernel, would be my guess.
Hmmm, I thought automatic meant automatic. My bad. J/K

Yes, automatically too bright in most situations. Yet not bright enough in sunlight.
I almost need to cover the light sensor some to fool it.
This is where Samsung fumbles. Their software is poor. Whomever is writing the code, set the light sensor to brightness conversion wrong. At least on DL30 they fixed one mess up. On the original rom, when you plugged in external power, the brightness would go to a fixxed level. If you were outside in a car and plug in power, it would dim the display. Indoors at night, plug in power, and it would BRIGHTEN the display. What's up with that.

Whats wrong with manually changing it? It doesnt even take 5 seconds to change the level.

What's the purpose of having a light sensor if it never works?
Often when I pop my phone open to do a specific task, '5 seconds' is about as long as it would have taken to do that whole task. And it's just annoying to unlock the screen, begin to attempt doing something, and then notice 'oh hey, the screen is basically unseeable!' and have to interrupt whatever you're doing. Or, even worse, when you're going from place to place and go through areas that are lighter and darker, forcing you to keep interrupting your work.

You guys nailed it. The screen is far brighter than I need while indoors at the office, but step outside and it just doesn't keep up with the bright Colorado sun (I can adjust it manually to a level that can be seen in sunlight just fine).
I could spend 5 secs adjusting the backlight each time the light environment changes, but why not spend 30 min optimizing the auto brightness levels and then never have to worry about it...
I know with my Moto Droid, someone had made a code that altered a particular file to change the lowest brightness level, but I have yet to see that for the Fascinate. It's a shame since the Fascinate's screen is so much nicer, but not set up optimally.
I know some dev's had also integrated the ability to change the auto brightness levels within custom ROMs for the Moto Droid. That'd be a great feature on the Fascinate!

That is to peoples own preference. I use auto most of the time and its fine. Doesn't work would indicate it doesn't change the brightness at all.
You can't expect it to auto sense it to every persons liking. Also does power control change it so you can see the screen, cause that doesn't take '5 seconds'

Try Screen Filter - its in the app store. With screen filter applied I keep my phone set to auto and screen filter reduces that more - in my case 50% more.
Well in the DL30 rom you don't have to go to the settings menu to change the brightness, just press and hold on the notification bar and then slide left and right to change the brightness.

Ill check that out. Thanks!
Good afternoon,
I do not know if it is something normal or it is a real problem that requires technical support. The case is that I have the mobile without automatic brightness, and when I set the brightness to very low levels, when unlocking the terminal, when you turn on the lock screen with the wallpapers, it appears as a slight flicker of the screen, thousandths of a second, almost imperceptible if you do not stare. Something like when you start to light a light bulb until you get to have light at all, but with a very slight flicker.
It is not an extreme flicker that completely turns off the screen or any of that, it may even be the operation of the brightness sensors (which happens to be strange because the automatic brightness is off), but I worry that it may have more problems in the future. Also I have noticed that having the brightness to the maximum of half of this problem does not occur, only with low brightness. There is also no blinking once unlocked using the phone itself, everything works perfectly. It is as if the lock screen was automatically adjusted when unlocked.
Should I contact technical support or just foolishness of mine?
Regards and thank you very much in advance.
PD: I have EMUI 4.0, NXT L29 with b192
Maybe you can upload a video so we know what ur talking about.
I think I've actually noticed something like what you're describing in my device. In summary, ever so slight flicker of brightness when display is on low/lowest level with automatic level off. I assumed it was normal

I also think it's normal. It's like an automatic contrast adjustment to accommodate the eye to the screen. I think it's a matter of the IPS NEO screen.
Does anyone else have this?
