just wondering what people think about this - im finding whenever I open my email the screen flashes bright for half a second and then dims down. anyone know why this is? is it design? a glitch? power surge? is the brightness limited to save power? (if so where is the diagnostic setting to change it ?)
it does it even on full brightness.
just seems a little weird is all!
That's because of the Amoled-screen.
When displaying a bright white background, the power consumption of the AMOLED-screen goes through the roof. Therefore, whenever a large white area is detected, the screen brightness is automatically decreased.
It's not just in the EMail-application but always when the background is white.
Hi peoples
Does anybody know of a way of reducing the backlight brightness below the stock settings?
I've tried various screen filters, such haxor Screen Filter, but these apps are rubbish IMO. All they do is apply a grey transparency filter over the screen, they don't actually reduce the backlight brightness The result is a trick, the screen looks darker but it's really only because the white pixels are made grey. The problem with this approach is that it messes up the contrast and colors, and gives a washed out look.
I like to sometimes use my N10 in a pitch black room, which needs a very dark screen. My old Galaxy Tab 8.9 was good for this, because the backlight was able to go much darker than the N10. The thing is, I know the N10 hardware is capable of having a darker backlight because if you don't touch the tablet for a few minutes, the screen first goes dim before it turns off.
I would like to be able to manually activate the very dim screen setting, or better still, have a lower brightness range available in the brightness settings.

[size="5]Power Consumption[/size][/color][/b] [b][size="5"]&[/size] [size="5] Battery Saving[/size].
Hii XDA members & moto g users this thread contains everything u need to know about the battery consumption of ur android phone & how to save it ..because it can add some precious hours or minutes when u run out of battery
Most android users must be very curious to know about the power consumption parameters of their Android phone.
How much Power does each component or a Android service consumes ??
This Guide provides full power consumption distributed and well explained...
This might allow you to save some precious minutes of your Android Smartphone Battery.
DISPLAY: Average - 370mW.
Full white background, 1% brightness - 450mW.
Full white background, 100% brightness - 960mW.
So roughly every percentage of brightness increased accounts to additional 5.2mW.
NOTE :- (Amoled Screen) Now we know why using dark wallpapers and reducing brightness is so important than undervolting.
Virtual Hardware Keys - 40mW
Led lamp next to camera - 1.3W
Camera - 700mW
Bluetooth - 110 to 180mW
GPS - 110 to 180mW
2G to 3G switching - 800mW for 8 seconds. (This is no h/w component, but we should know)
CPU -
1.2 Ghz full load, 100% brightness - 3.8W+
1.2 Ghz average - 3.2W
Deep Sleep - 200mW during suspend state opposed & at deep sleep 8mW without BLN.
Wifi download - 1.51W
2G download - 1.598W
2G upload - 853mW
3G download - 2.403W
3G upload - 3.136W (Stay away from uploading your videos to youtube via 3G)
Press Thanks :thumbup: If I Helped U
This is awesome guide thanks op for great information you shared
It's surprising that there isn't much difference between 2g and 3g download.
Also, could you tell us what's the battery consumption when using black wallpapers, especially on non AMOLED screens?

Battery consumption using a Black Wallpaper is as same as using a White colored wallpaper on ur Non Amoled display.
But different brightness levels can make a difference on ur battery life. U may reduce battery usage by reducing the brightness on Non Amoled displays as on low brightness the intensity at which it emits light from light source (LED) will be low, so that will SAVE ur smartphones battery & completely opposite at full brightness as the light source emits light at higher intensity, that increases the battery usage.
Using Black Wallpaper on a Non Amoled display does not count to save battery. In Amoled display each pixel backlits itself when its needed.
So there is difference to some extent when u see a Black wallpaper set on a Non Amoled phone & a Amoled phone.
Black color on Amoled displays are Tru Black as compared to LCD displays which doesn't look tru black.
In LCD displays there is a LED bulb behind the display panel which spreads the light across the screen so even if u use a black wallpaper it will not decrease the battery usage ..it will continue to consume same amount of battery as the LED bulb has to generate a black colored pixel by keeping the LED constantly switched on.
But in Amoled displays when u set a black wallpaper the Black part of the wallpaper is not required be lit up (individual pixels have their own light source) & it would look the same as when u turn off the screen.
Ex ... If u set a wallpaper which is divided equally into two parts the upper part is full black & the lower part is full white.
Now on
1) AMOLED :- only the lower part with white color will be active as the Black color part does not need to be lit up by any source because its Tru Black as each individual pixel has its own light source. Hence it save battery
2) NON AMOLED :- here the entire screen will be lit up as the light source is behid the panel and it has to continuously keep on emmiting light to make the white part visible.
So u may notice when u switch off ur moto g when the phone is about to shutdown a black screen appears just for a fraction of seconds & then completely turns off, thats an example of Non Amoled display because ..here even a black pixel needs to be generated by the LED behind the display. Which does not reduce battery consumption.
But black pixel need not to be generated on Amoled as its is can stay off & only display the essential colorful parts which saves battery.

Wow! Thanks for such a detailed explanation man. I knew the basics of the AMOLED display but you really explained it well.
Oh and so it really doesn't matter much right, if one doesn't change to 2g at all?
Because the battery drain is almost the same? So all we felt was placebo?

The battery drain on 2G & 3G depends on the frequency of the band that is being used at that moment. But battery consumption is probably more on 3G as it operates on higher frequency bands & switching from 2G to 3G also consumes some amount of battery as the band is reset to default & scaled to a higher band after a 3G network is found by the signal reception counter. 3G consume more battery overall.
Please check the 3G download - power consumption i have updated it.
It was a typing error
Last night, I went to use my night clock app with my new LG v20. On my Note 7, the screen was totally 100% black except for the numbers.
On the v20, the entire screen was stil lit - faint, but clearly still lit up in a light light grey.
Is this just how an LCD screen works, or is there something I have to do in order to get the rest of the screen to go off.
(Note, this includes the 2nd screen which was also lit - and I had the brightness at 0%).

BTW, this may need to be a separate thread - on my phone I notice that the auto-brightness tends to be too dark. Any way I can adjust it to be brighter when in auto mode, or should I just go to manual ?

Try turning off second screen and see what your results are.. Second screen has a seperate black light that slightly bleeds out to the rest of the screen. It was horrible on the V10 but much improved on the 20..

The night clock app has the option to turn off the notification, which also turns off the 2nd screen.
...oops. It did, until I followed your suggestion in the other thread about the more setting to enable time/date when in full screen or notification bar hidden. I'll have to get into the habit of turning *off* the more setting at night.
(Either way, doesn't help with the slight gray background color. I can probably just get used to it as long as I'm not damaging the screen by having it slightly on all night. I need to google if LCD screens have burn in problems I guess.)

Maybe I should just start pm'ing you all my questions

Use comfort view on low or medium. Will help lower the ~9000K color temp some and help blacks a hair. Faint glow is typical on LCDs. Higher quality LCDs and higher quality led's can help. Lg skimped here. Sucks they didn't even give us color modes to pick from. The colors are waaay off. But using comfort view dims the blue pixels and helps considerably.

That's just how LCD works, they need CCFL or LED back light to lit up the screen, it's not possible for it to be completely black while turned on. With AMOLED the individual pixels can turn off itself which is why the black are blacker on them. OLED screens also have very high refresh rates which eliminates flickering, this is good for people who are concerned with eyes health.
Lcd doesn't get burn in, but it can get ghost image retention. It was f***ing horrible by the end of my V10 usage.. Never had the problem on the G2 3 or 4. Just the V10, even after factory resetting.

Had the same issue my V10, that is my biggest V20 concern. . My v10 was not even a year old.
I get the engineering and cost reasoning, but not sure I like the lcd screens.
i recently bought a used s7 edge. the cellphone's display is damaged buf overall it works fine. except for a few issues mainly related to light sensor according to my understanding.
1: the display flickers when auto brightness turned off or when brightness is set to anything less than maximum
workaround: i installed screen filter app to control the brightness
2: the screen goes to green screen of death when device is put to sleep
workaround : turn AOD to always on and never Turn it off
3: the display goes to green death screen during call and wont get normal unless call is ended and screen is locked and turned on..
4 : at AOD ,the screen flickers at night time or in a dark place but gets back normal in bright light..
info i need : i thought what if it was possible to change the android framework values for the light sensor so that no matter whatever the light of the surrounding may be.. the device will always think it's in bright light.
for example if the settings for current values are
high 5000 medium 2000 low 600
then i change it to
high 1000 medium 500 low 25
so that the device will always think its in full bright area..
can anyone help me in achieving this goal? thanks
