Hello there.
New user, first post. I've searched if there was anything related but found nothing. If I missed something, moderators can merge or whatever.
Well, it seems you can see the Defy's current charging indicator with the phone turned off, *without* pressing the volume buttons.
Here's how:
1. Make sure the screen is clean (no crust, oil etc);
2. If you're using a screen cover, it might be best to remove it;
3. Charge your Defy with it switched off;
4. In a place with preferably sunlight, look at the screen from the side, at a 45 degree angle and adjust. If you look carefully, you can see the battery indicator!
The catch: Even when charging with the Defy switched off, the screen is partially on, albeit very dim indeed.
Maybe someone could take a screenshot?
Have fun.

isnt the charging status just shown on the screen anyway?

When the Defy is off and charging, no. Press the volume buttons for the charging status to appear in all its glory.
Whether a feature or a defect, perhaps this is configurable somehow.
Examples:
1. Adjust (with the phone on) the screen dimness for when the phone is off and charging, so one could see from a distance how much is done;
2. Screen indicates when charging is complete (flashing for instance).
There *might* be a slight decrease in the charging time if the screen is completely turned off, but I don't think it would be noticeable.

I was thinking that since the OLED screen does not use any backlight, lighting up a few pixels just to form a little led blinking would not tax too much the battery.
I don't know, however, whether waking-up the phone entails significant increase in battery usage. A middle solution would be to wake it every 2 minutes for 10 seconds in order to display the notification and the let it sleep again.
What do you think?
Sounds good good but im not to sure about that... there was another post about having the illuminating back button flash, maybe both menu and back buttons.. alternating between each one with a speed setting?
i love the idea, but the screen is 'off' for a reason...
first of all i don't know if oled screens can 'burn' (meaning the pixels are still showing when they are suppost to be 'off', because they have been 'on' to long)
Also, if it means the chips that control the screen have to be active instead of inactive, your battery drain may be kinda big....
I don't know that OLED would have burn-in (that's more a CRT thing), but they might well burn out - they do have a finite lifespan.
But you're probably right, it would likely mean that the phone couldn't completely go to sleep.

well, in such a case we could rotate randomly the pixels to be lit up (as in real old time screensavers).
With regard to out of sleep battery consumption you have a point. Maybe we could just wake it up for a few seconds and then have it sleep again. In any case if we assume that the major battery draw is the typically screen, then such an arrangement might prove to be acceptable - at least in some cases.
Why not use the backlight on the menu and back button? They shouldn't use too much power or get burned?

Yes - I agree this is a very good alternative - yet I do not know how bright these leds are.
Nevertheless, I noticed that the screen is able to display a big animated icon of the battery charging even when the phone is off! (I just received it and I put it in the charger). Thus, I assume there is some kind of control of what the display shows without having to wake-up the system (at least the whole of it).
If this is the case, we could have some led like notification even when the android is in sleep!!
what you say is not necessarily true.. that icon is when the phone is off. which does not translate to being able to display something on a sleeping phone when it is on.. two totaly different issues ..

True. I will check whether it is displayed when the phone is on sleep (still off and charging). It implies, however, that the screen can be controlled (also?) independently of the OS.
(all in all the touch buttons respond / light up when touched though the phone is off and charging).
Go guys!
I'm waiting this modification to buy this phone!

Up !
Very funny topic one year later !
NoLED, BLN ...
The community is very powerfull !
Thank you all
Guys, just search NoLed on market and it's already made ^^. However, following neldar thread on BLN, NoLed use about 10% more battery per hour than off screen. BLN which is found in most of the kernel ( Except damianGTO one ) use about 1% more battery per hour and turn on the backlight of the touch key. Hope this will help you
I'm no developer so i have really no idea if this would work.
But, as this mobile is a AMOLED screen, each pixels are lighted up and so not much battery is drained on a black screen.
What if we could somehow make something when a new sms has not been read and screen turns of, a black screen like this appears
Is something like this possible?
pic example, could even be smaller or just 1 blinking pixel.

I think to display a message on screen the machine would need to be awake, so it would be using more power than with an led notification (afaik the device can normally go to sleep then).
Your idea would still save power over just showing the lock screen though because you are right that using fewer pixels would proportionally reduce power usage of the screen.
I guess the hardest part would be making the device appear off - It would need to ignore screen and button touches (except power).
I hope someone can confirm if this is a bug or not!
Whenever I turn off my screen, and then on again it takes a second for the screen to auto-adjust the brightness up or down. (depending on the light-situation!)
Isn't the light sensor supposed to know what brightness to be at even when the screen is shut off? It's as if it first detects the light-situation when I turn on the screen. Could someone please try (in either a very dark or light room) try shut off screen, then back on and check if the brightness has stayed the same or if it first adjusts it when you've turned it on?
Why would it monitor the light when the display is off? Seems like a waste of power to me.
I doubt its a bug. More like a powersaving feature.
That's normal AFAIK.
The light sensor turns of when the screen goes off, to save a few milliamps I presume.
To my knowledge this is normal, its how mine operates as well.
Sent from my Desire HD using XDA App
It's like that on mine too. I think that all sensors are turned off when the screen is off to save battery.
[SOLVED] Bug in Auto-Brightness?
Alright, thanks for the replies. Just didn't notice it till now and it sort of bothered me.
So I can't seem to figure out why the Soft Touch Button are on, or mostly not on on the One X.
In a dark room they are not usually on, run some app or open something on the phone and they seem to activate.
Anyone else getting this??
They should activate/deactivate depending on the amount of surrounding light.
Tested it myself, with a flashlight on the phone the lights went of. When I removed the flashlight and back in the dark, the lights turned on.
Yes, I got the same result as Foggy79. I just want to know if I can turn if off manually?
Probably not (maybe with a custom ROM, but I doubt that)
I wanna know how to turn them off. When watching a video in the dark.... they stay on, when they should turn off when video is being played full screen.

Use this Rom :
http://forum.xda-developers.com/showthread.php?t=1625816
With PKMN Tweaks integrated in this rom, you can control soft key led back light :
* Always on
* Always off
* Turn on when the dim light, turn off when strong light

would rather not go flashing roms to get this.
And how would the tweak help? either it's always on, always off or the last option which would keep the lights on under dim conditions.
What they need to do is add a timeout. like on the Galaxy series phones. 2 seconds or 7 seconds. then it shuts off, when you touch the screen it turns on again.
It's just bad designing and/or programming.

That'sa great idea, which I can't believe I didn't think of. I have been having the opposite problem: the soft key lights always stay on. However, when I held up the phone to a bright light, they turned off. So, they are working.
Still, it takes a really bright light to achieve this; I wish I could fine tune the behavior. I tried an app that stated it would control the keys but it did not work (and my phone is not rooted).
I also see in ancola66's post that the custom ROM allows automatic dimming only in "strong light," so apparently the behavior I am seeing is normal. I wish it would take less strong light to activate dimming/off as my lights never seem to go off, as I stated.
Thanks for these informative posts.
Reading in bed with Aldiko
It mostly annoys me when I'm reading in bed with Aldiko. Aldiko is a great reading app that lets you adjust the lights the phone emits to the lowest possible, so I can read in the dark without disturbing my wife.
However, on this phone I have the keys glaring in my eyes, way brighter than the letters of my book.
I wish I could switch them off somehow.
I thought the soft lights will only turn on when phone is in dark place? Correct me if I'm wrong.

Exactly.. That sucks when lying in bed reading next to your beloved.. It should only light when touching the screen like the s3..I don't need those lights when I sit and read a book or something

There are ways to disable them. Mostly(maybe a must) if you are ROOTED.
Apps that ppl said that were able to shut them off were screenfilter or how its called. Search through the forums here.
Or you can edit the framework-res file to disable them on sense roms. If Interested I will search it from here somewhere.
Or for CM check my signature (there are 2 lines, not the one about the UV...)
They annoy me too. I recently began watching some videos in bed (streaming from desktop) because I temporarily gave away my laptop. They are very bright in the dark, I wish there was an option to turn them off permanently (yes, I know it's possible with custom ROMs, but I'm still not ready to root yet).
Also, the display is still too bright for my taste - lowest brightness should be lower. Although it's pretty good compared to other screens. In my opinion, the lowest brightness is also very important, just as max. brightness.
My wife cracked her Redmi 7 screen so I ordered a replacement screen+digitizer+frame from a reputable seller on AliExpress. I followed a guide to the letter and made sure not to damage anything while disassembling, and the re-assembly with the new screen went smoothly.
When I power on the phone the Xiaomi logo comes up nice and bright, but it then auto-dims in the usual way as it loads the system except it dims to an extreme level. I mean it dims so much I can only see what's on the screen if I go into a dark room/closet. When the system loads I can navigate menus normally (as long as I'm in a dark room) but changing the brightness setting has no effect. Turning on/off auto brightness does nothing either.
It doesn't seem like there's anything wrong with the LCD, because if I reboot to bootloader it sits there with the Fastboot logo and picture at full brightness until I turn it off. I took the phone apart again to check if there was anything obstructing the light sensor and I can't see anything wrong with it.
Has anyone seen this before?
Thanks
