Hi!
At the beggining - I'm sorry if you won't understand something. English isn't my main language, I still learn.
In some smartphones with AMOLED screen (such as Samsung Galaxy S4) black pixel = turned off pixel.
I've always been irritated because of the fact that our batteries aren't too great, but phone producers still produce their phones with hiper-resolution, which practically we cannot even see.
I have invented something, that later I turned to real app.
I call it Pixel Battery Saver, because it displays some kind of totally black mesh on the screen (you can change its density), so at least half of the pixels (or more) are turned off (so the screen consumes less energy!), while you are still able to read anything on your screen.
If you still don't understand, just take a look at the screenshots.

I've already created this app.
You may download and test it for free,
but if you really appreciate my work - I would be grateful for every donation (every single dollar would be helpful).
Let me know if you found any annoying bug or misspelling. This is my very first app - I still learn
FAQ:
What do I need this for?
- Imagine this situation - your battery level is really low, but you have to search for something important on the Internet. Making the brightness lower often isn't enough. That's when you would need my app - to turn off some count of pixels.
There are lots of apps that dim the screen...?
- This app works different. It doesn't overlay your screen with transparent image (but there is such option in premium version if you need it too). It overlays your screen with totally black screen, which makes some count of pixels off, to prevent them from consuming battery.
Do I really need AMOLED screen?
- The best results you can get right with AMOLED screen, where black pixel means turned off pixel. However, even in other type screens black pixels are saving some battery, so it's just worth to check.
In battery stats I can see that this app consumes a lot of energy. Why?
- Don't look at the stats, look at the real battery consumption. Probably, Android Battery Stats app "thinks", that this app display an image on the screen all the time, because of what it shows an information about consuming energy. In fact, this app turns OFF the pixels (in AMOLED screens with this function), so it SAVES that energy, not consumes.
When the mesh is on, I am unable to install apps (Install button is disabled). WTH?
- That's because of the Android Security. In premium version of Pixel Battery Saver I added an option to bypass this protection. In this free version you can simply turn off the app (by clicking "Turn off" button in Settings window) before installing any app and then turn on it again.
Density of the mesh that I recommend is "High".

There are a couple of issues with the concept as you've outlined it.
1) Turning off 50% of the screen you make small text unreadable. Even in your example the not so tiny temperature values are illegible.
2) While this would definitely conserve power in terms of physically lighting the screen, it might not be by as much as you'd think. The screen has multiple power sucking components. The first is the light producing LED's. Turning half of them off saves half the power. Simple math
. But the GPU that processes the screen imaging still runs at full speed even if the screen is blank. While the LED pixels aren't working, the GPU is still working to render a black image. So turning off half the pixels doesn't reduce the power draw required to run the entire display to 50% in total.
3) The app that overlays the black mesh will require the GPU to work overtime. It's got to render the image that's supposed to be in the screen plus it's got to render the black mesh over the native image. That could potentially use up more energy rendering the black than the black saves by not lighting the pixels.
4) The already built in option is to just turn the screen brightness down 50%. It accomplishes the same goal, requires no additional image rendering, and preserves the original image design without loss.

1) Why do you think so? As you can see on my image, it doesn't make the text unreadable (if the "mesh" is pixel-by-pixel)
2) Right, but everyone know that black-layout apps are muc better for our battery than colorful or white, right because black screen isn't that "hungry" of power
3) Ok, but there are lots of apps that creates a full-screen black (transparent) overlay to make the screen more "shade" (dim?) to save the power. It works, even thou all the thing you described in #3
4) Oh, right, but when my energy power is really low, I turn the screen brightness to the lowest level, but it still consumes a LOT of energy.
Anyway! This discussion isn't even important, maybe we should just CHECK if this may work, or if not?
But, as I said, I am just asking someone to create a simple app like this.
Thanks anyway for reply.
Really? No one?

it's not worth in my opinion, while rendering half of the screen black would help save some battery, the saving wouldn't be so great, yes the screen is what burns the most battery on android but, its not just having it on, its having the phone out of deep sleep, having the touch sensor activated and registering touches, etc, not to mention it would just kill the great viewing experience that the phone offers.

Though when we are using our phones it has to render the whole screen anyway, so I think rendering a half of it would be better?
I am not thinking about this app making our screen always on. I just mean to display this mesh when we are using our phones and the battery level is low.
And, of course, it would kill the viewing experience, but when your battery level is 5% and you have to do some important research on the internet - you don't care about the viewing experience.
If you think turning the pixels on is not the thing that consumes the most of the battery, then turn the brightness to the highest level and then to the lowest and see how much it consumes... (changing the brightness doesn't change anything with the touch sensor and other thing you described though)
I thought my idea is really simple to develop for any Android developer and to see if it really works...
I think that if you do some comprehensive tests, you could bring some attention.
Create one image with this pattern, put on your phone and open it with any image viewer, put the bright on max. Let it run for some time.... Measure how much battery was sucked.... Test again with the same image, but without the pattern, do some statistics with the results.
Are you rooted? You could invert screen color or make it grayscale.
That's exactly what I was thinking about. I will do this tomorrow.
I'll post my quick opinion. It really depends on how the phone handles the screen, but my experience is from my old Galaxy S2 with NoLED running over night. I think NoLED program was essentially accomplishing what you are proposing (i.e. rest of screen is "off" or black) and on portion of the screen is on for the LED to hop around. However, even though the screen was black the screen was still draining at a quite high rate (~6%/hr on average). The screen needs to be "off" not just black in order to save more power.
But having stated the above, I am looking forward to your test results to compare and determine if it can save more battery.

Thanks for your opinion, but the screen in s2 is way different than on s4. The screen in s2 doesn't turn off the black pixels. The one in s4 does.
II am looking forward to do this test tomorrow
I think this would be like a filter app, such as the found in Play Store.
Exactly. I was talking about it but I forgot the name. I next hour I will do some tests.
Ok, thread can be closed - I've created this app by my own. I mean, I used many of tutorials and examples, and finally got it. Thanks anyway.
Could you share your findings?
This would be pretty hard, as I have read dozens of sites and forums to understand everything. There wasn't any quick or simple solution.
Did it work and save as much battery as you expected?

I still do not know, I have to test it multiple times to be sure.
Ok. I think it really works, but I'm still not sure. Give me few days to share the alpha version of my app (I just want to add some extra functions).
By the way, does anyone know where should I look for a list of phones with screens like in S4? I mean where the black pixel means it's off.

Since the initial release on Aug 2010 as the first one click instant access app and its super unique always available design , Smart Taskbar has became the origin of several similar one click instant access app in Android Market today. Today, after more than 6 month of beta testing, I am proud to announce that Smart Taskbar is finally going to V1.0.0 stage. V1.0.0 is more stable, faster, more feature packed and also more visually appealing than its previous - beta testing product.
Smart Taskbar is a - super launcher, task switcher, an app organizer, shortcut manager, and widget viewer that you can quickly call up on any window by swipe the edge of screen or by clicking a transparent trigger icon on screen. In most cases, you can complete app launching in 2 finger clicks (1st swipe, and 2nd click on app icon to launch). Possibly the fastest way to quickly launch or switch between applications.
If you want to use your phone one handed with complete touch screen experience, you find Android takes too many steps to complete one simple job, or you want to get a faster way to get things organized, get Smart Taskbar to make your like easier.
Smart Taskbar comes with following features
(1) 5 speedy launch spots for 2 steps quick launch
(2) App organizer function built in
(3) Task switch
(4) super speedy launcher
(5) Software home button (To prevent H/W home button from tear and wear)
(6) True multitask experience!
(7) Able to build your own custom action to launch
Reason why to use Smart Taskbar:
(1) Free up your home screen for more widgets instead of app shortcuts
(2) A better way to organize app in to groups
(3) Need a super fast way to launch your app
(4) Missing the multi tasking in Palm Pre
(5) Don't want to press hardware button too frequently

Get Smart Taskbar by searching 'Smart Taskbar' in Android Market.
great app
thanks for posting this good app, it is so greate and useful that i use it every time when i use my phone.
i like the quick luanch function most, hereever i am, it is easy and quick to switch to another app.
also i can organized all my apps by different lables. then i can catch it easily by related lable.
of cource it goes smooth on my phone and till now, i have not found any defect to remove it.
my pleasure to share it with everyone.
Nice app. Uses a good amount of cpu tho and the visuals could use a bit of polish but definitely effective. Looking forward to see it develop.
Hi,
CPU usage if Smart taskbar should be no different than regualr Android app. You are seeing high CPU occupation because you do a lot of scroll in app list. Try yourself and scroll grid list in other app such as gallery and you will see similar CPU usage.
Since getting my Legend over 4 months ago I've been looking for something like this.
This seems to fit the bill, I will be sure to check it out! Just hope the CPU related comments are as per the OP's response ^.
EDIT: Oops, not what I thought it was. I thought this would 'pin' certain apps to the notification area for quick access.
Yes, you are correct the scrolling taxes cpu on any app so that is fair enough. I would like to see widgets integrated somehow similar to the way power strip does and I would use this exclusively for sure.
I am really happy with the app. Works great and has let me clan up my home screen. Much better then I thought it would be.

It is truly a personal preference question. But notification doesn't show up in full screen app. In this case, u can't access to quick launcher. In addition, u need to (1) expand notification bar, (2) click on notification item, (3) click on the item u wish to launch. It is 3 steps. Anyway, just like i said, it is pure personal preference question. Hope you can find it useful eventually.
Wow, works great and is just great!! This is definitly a Must-have app!
I was hoping to give this app a try, but the developer decided to pull it of most non english markets see http://kiumiu.wordpress.com/2010/08/27/closing-most-non-english-user-on-market/
Can anyone give me an apk so I can give it a try?

Looks like it would work great - but DOES NOT scale, if you've changed your LCD density. The click button to slide it out shows in the middle of the screen!
If the scaling issue gets resolved, it would be fantastic. In the meantime, it's very difficult to use it if you've changed the LCD density.
EDIT: Found it using an american ID on market-enabler, looks like its still in some of the english ones.

That's what I was hoping for too...
I like this overall, but I do think it has a few weaknesses.
First, app scrolling is very slow, I'm used to fast scrolling in my device whether it's LauncherPro or Touchwiz. I'd be willing to deal with cached icons or anything else for a short term fix. (Korean Galaxy S, SHW-m110s)
Second, while in the app I can't use my home button, which means, if I want to use home button to get home I can't. It also means I lose access to QuickDesk while in your app.
Overall, I'd recommend this, especially to those who don't use something like QD. Still, this has a more complete experience than QD so that's a definite plus over it, but QD has a real speed advantage as well as it's where I put power control widget for it's easy access within apps. I could see using this heavily with faster speed, even still due it's customizations that I haven't yet utlized it's probably better than I've already stated. Thanks for the good work, Dev, looking forward to more!

Same here. I can hit the 'open' button, but if I press the settings icon...it goes to the 'how to use' screen with the blue hand on it. The only thing I can do from there is open the dock...which works...but I would really like to access the settings menu. I am keeping the .apk, but have uninstalled as of now for failure to access settings.

I initially had the same problem. I think you have to click "dismiss", then after that, access settings from within the main screen of the app (it might've been from hitting the menu button, but I don't think that was my method, though they probably do the same). There are only 2 settings in the "settings" menu though. Other settings/customizations will be found within the app itself, such as pinning most common favorite apps to your easy to launch area.
I'll edit if the developer corrects me on anything, I only played around with it for about 15 minutes.
Like I said, I basically like the app, however, I encountered a big problem with it in the past 12 hours since my original post. My "Android OS" usage shot through the roof when I was asleep. I'm a guy who, at least when at home and definitely when asleep, doesn't use 3G, so I leave it off. Also, I don't use sync, so my Android OS is typically very low 2-4% and I get insane standby time in my Galaxy S, 1-2% drain in a typical night. Last night, I probably drained at least 30% but I think closer to 40%. Something is going on with the app that doesn't let my phone stay in standby mode.
Then this morning, I was very tired, so perhaps I slept through my smart alarm (it's somewhat quiet, though not very, and it'd only be the 2nd time and the first time the speaker was blocked). I was surprised when I was woken up by a backup alarm on my phone, so most functionality definitely remained. But then, 15 minutes later, my last resort alarm didn't go off, and I was monitoring the phone a bit to make sure it would. Right after it was supposed to another (very stable app, not to be named) force closed for maybe the 2nd time in it's life on me (no update in at least a week). Right after that, my power button wouldn't function to turn my screen off, it still brought up options to do things like Airplane mode, power off, etc, but touch to turn screen off doesn't work (and I leave my timer off).
I think updated I'll really like this app, plenty of potential here, but I have to uninstall. Thanks though.

Hi,
I am developing on Galaxy too. Your phone lock up issue is basically caused by smart Alarm. when it happens, Smart Alarm doesn't make any sound, CPU usage of Smart alarm goes to 60-80%. At same time, my phone gets so hot like 40-50 'c. I am very sure this will happen to you even after uninstalling Smart Taskbar. Not using Smart Alarm is the only way to solve it. I am not sure is it fixed in later firmware release. In addition, my app doesn't use any wake lock. Therefore it doesn't block your phone from going to standby.
For battery life issue, I have used SystemPanel to monitor one week CPU time usage of my app, basically it uses less than 0.1% overall. Therefore, should have very very small battery drain.
For slow scroll, I do use cached app list. Launcher Pro is simply too great. Nothing can compare to its super smooth scrolling so far. But I think my app performs on par with standard launcher
By the way, are u using Galaxy S or the old 7500 Galaxy?

Hello,
I am not sure is it a bug but plz make sure you click the dismiss button. I think a reboot can solve it if pressing dismiss can't fix it.
Update: While GalacticNight is still available for older devices, if you have a newer device it probably won't work. But if you have Android 4.4 or higher, my new Color Changer app may work for you and will do everything GalacticNight did (but alas at a higher software level). I am therefore discontinuing work on GalacticNight.
Edited: Now in Google Play.
Galactic Night, now in the 0.99rc2 version, provides red, green or sepia (or blue if you really want!) night modes for rooted OLED Galaxy S2, S3 and Note 1 devices (not tested on Galaxy 7.7 but might work). You can invert the screen colors (so you can browse in white on black, or green on black, or red on black). There is also an Outdoor mode which washes out the colors but might improve legibility outdoors.
I like reading ebooks in green on black when in the dark.
As of my present knowledge, various pre-release versions of this have been tested on:
Galaxy S2: Gingerbread and ICS
Galaxy S3: ICS
Galaxy Note: JB
It should work on ICS on the Note as well, but I don't have any reports. GN works by adjusting the mDNIe profile. If you have some Samsung device I haven't heard of which has a Screen Mode setting in the Display settings that includes Dynamic/Normal/Movie options (and maybe others), there is a chance that this will work for you.
My benchmarking has not shown any statistically significant impact on graphics rendering speed.
Use at your own risk. If a mode screws up the screen display, you should be able to get back to normal by pressing "Standard" or rebooting, but I offer no guarantees.
Several users have asked for customizable settings. These could easily be provided, and could adjust for screen color tint and so on, but I haven't implemented them yet. I might in fact leave those for a Pro version.
You might be curious how the nightmode differs from that in ChainFire3D. ChainFire3D's nightmode works by dropping channels. E.g., in red mode, it simply drops the green and blue channels. This means that things on screen that were in pure green or pure blue get changed to black. Galactic Night uses a different color adjustment which is equivalent to this algorithm: first convert the RGB color on the screen to a luminosity, and then use the luminosity to set the night mode color. Thus, in red mode, pure white will go to maximum brightness red, but red, green and blue will go to different shades of red. This preserves a lot of the legibility.
There is also an odd "No blue" mode which converts RGB images to RG images, so white goes to yellow, blue goes to a dark yellow, etc. I've heard that blue light makes it harder to fall asleep, so it might help with falling asleep if you switch your phone to "No blue" mode for an hour before going to bed, if you can tolerate how ugly it looks.
Here is a photo of GN in action. It is not possible to take a screenshot of it in action, because the color changing is done between framebuffer and display, so the framebuffer that the screenshot accesses will not reflect the color changes.
I've already posted about this in a few device-specific forums, but now it's ready for wider dissemination.

Let me add that the green mode should nicely help save batteries. Using just the green subpixels should use about 1/3 of the power, and yet maintain a lot of visibility because our eyes are very sensitive to green light.
Users report that on ICS there is a 1/2 second flash of the regular colors when you turn the screen on. In 0.99rc3 I implemented a red-and-black logo overlay that should cover up most of that flash (it doesn't cover up the status bar, alas). I can imagine it would be really annoying to be in the dark and get a flash of white light even for half a second.
Reports would be appreciated.
If the logo annoys, you can turn it off in GN's settings.
Great app. Works well. Having no trouble with the logo for screen on.
I'm not sure how difficult this would be to implement, but it would be useful to have a tasker plugin so that red mode could be activated when you run certain apps or at specific times of day.
Keep up the good work.

The description for the app "Filter your screen" specifically says that you should avoid monochromatic filters which are not grayscale, in order to avoid some kind of burn-in, and thus a permanent tint on our (AM)OLED screens. Do you know anything about this?
I'd love to use the red or green filter, but I'm not sure I dare to, at least not for any significant amount of time.

I'd love to use the red or green filter, but I'm not sure I dare to, at least not for any significant amount of time.

I must say I haven't thought of that. That's an issue. But it's no more an issue than if you heavily use an app that uses a single color. Or if you heavily use an app that has a single bright display element in one place.
It's going to be more an issue if your background is all white, and then it turns, say, all green, and then the green subpixels burn out faster than the red and blue. But if you use green+invert with that, then you will have a lot fewer green pixels, most of them being black.
Moreover, I assume the issue will be mitigated to some degree if you set low screen intensity, and most of us will do that at night. Just use my ScreenDim app at night and use a combination of the two sliders to set a very low brightness. (Or use ScreenFilter or something else like that.) However, this does mean that we probably don't want to use a monochromatic screen all the time during the day, unless, well, we want to use it all the time and hence the tint will irrelevant.
If the burnin does a uniform tint across the screen (which may not be the case), then we can eventually correct for it with a custom color profile.
Or you can alternate between red/green/blue modes on a regular basis.

Great app. Works well. Having no trouble with the logo for screen on.
I'm not sure how difficult this would be to implement, but it would be useful to have a tasker plugin so that red mode could be activated when you run certain apps or at specific times of day.

It would be easy to add Tasker support at the same time as I add launcher shortcuts.
I just posted 0.99rc4. New mode: Mono sepia. The standard sepia mode just changes white to sepia. Mono sepia changes white to sepia, and makes everything monochrome.
I've discovered a great use for the mono sepia and BW modes. The Kindle app screws up subpixel rendering (just as it is screwed up on the Kindle Fire), resulting in colored shadows around letters in some orientations (portrait on my S2, but this may differ). All the single-tone modes (sepia, BW, green, red and blue) will change the subpixel antialiasing to grayscale antialiasing, which to my eyes significantly improves appearance. (Subpixel antialiasing is wonderful--but mainly when done right.)
I just uploaded 1.00.
It's now in Google Play. Free, no ads (other than a link to my other apps). I am planning a pro version that will allow (a) automatic activation on boot (with some sort of safety mechanism in case you put in some bad settings like black on black--maybe if you boot with the device upside down or something like that it won't start on boot?); (b) custom modes.
just read the article on your app, and was wondering what you need to make this work on the Galaxy Nexus if it doesn't already work on it?

As far as I know, the Nexus doesn't support mdnie settings. Does it have display settings with dynamic, standard and movie modes?

This app is EXACTLY what I was looking for...except I have a Nexus S 4G
Any way it might get supported? Or is the display tech too different from the GS series?
Great App! i always found the darkes possible darkness too bright for night use.
is this only for stock roms or also AOSP built ones like Cyanogenmod?
Unsupported Device
App not working on Samsung Infuse 4g ( SGH-I997 ). It says Unsupported device or not rooted(it's rooted).

Hi!
At the beggining - I'm sorry if you won't understand something. English isn't my main language, I still learn.
In some smartphones with AMOLED screen (such as Samsung Galaxy S4) black pixel = turned off pixel.
I've always been irritated because of the fact that our batteries aren't too great, but phone producers still produce their phones with hiper-resolution, which practically we cannot even see.
I have invented something, that later I turned to real app.

I call it Pixel Battery Saver, because it displays some kind of totally black mesh on the screen (you can change its density), so at least half of the pixels (or more) are turned off (so the screen consumes less energy!), while you are still able to read anything on your screen.
If you still don't understand, just take a look at the screenshots.
I've already created this app.
You may download and test it for free,
but if you really appreciate my work - I would be grateful for every donation (every single dollar would be helpful).
Let me know if you found any annoying bug or misspelling. This is my very first app - I still learn
Density of the mesh that I recommend is "High".

Hey guys, I did a little testing (and I mean little) and here's what I found out.
So I got the screen at maximum brightness and left the screen on with a screenshot I made of the playstore, for about half an hour and then I launched the pixel saver and let that for about half an hour as well. Here's my results. (the battery percentage is directly android's battery)
time-percentage (w/o app)
1:50 - 53%
2:02 - 51%
2:11 - 48%
2:21 - 45%
that would be roughly 8% of the battery in 31 mins.
then with the app on maximum mesh setting
2:22 - 45%
2:31 - 44%
2:43 - 42%
2:51 - 41%
3:01 - 39%
so that would be 6% in 41 mins.
if we were to take just half an hour of both runs (w/ & w/o the app), in about 30 mins, the screen would drain 8%, respectively 4% (with app), so that's basically double the battery, or half the drain. Again, this is a "rough" test, a quick test, just to get a glimpse of how good this app is.
Here's the screenshot: *url * dropbox.com/s/tczkg3u5y4y8sni/max%20payne.png?dl=0 *url*
and pixelated: *url* dropbox.com/s/2fu7qf1ez2w90d1/max%20pixel.png?dl=0 *url*
if you zoom in the pixelated one you can actually see the pixels (I think those are real pixels, I don't know for sure, lol ) and the 2 pixel gap between them.

Similar to guky667's post about battery usage, I did my own quick run and here's the summary. What is surprising for me was that Medium density vs Highest density draw ~same battery life. I might do a second round of testing to confirm the mesh density and battery drain.
--- RESULTS ---
Common Assumptions
-Phone in airplane mode
-Screen = Max Brightness
-Screen has Whatsapp chat as the static image (black bg, colorful boxes, bottom grey typing bar, top green/gray bar for contact)
Case 1 = NO FILTER
7:50 = 62%
8:20 = 55%
7% in 30 min OR 14% in 60 min
Case 2 = Gray filter from GS5 UPSM
8:20 = 54%
8:50 = 49%
6% in 30 min OR 12% in 60 min
Case 3 = Pixel Mode (Medium = Usable still, sharpness is gone around edges)
8:50 = 48%
9:20 = 44%
4% in 30 min OR 8% in 60 min
Case 4 = Pixel Mode (Highest = Very pixelated)
9:21 = 44%
9:51 = 40%
4% in 30 min OR 8% in 60 min
--- END of RESULTS ---
--- Retested results ---
Case 3 = Pixel Mode (Medium = Usable still, sharpness is gone around edges)
19:09 = 63%

FAQ in post #3.
Changelog in post #2.
Download version 1.3.1 for free:
Always use the latest version with fixed bugs and new options.
[CHANGELOG]
v2.0 (coming as far as it's possible - see below):
- new option to automatically start service at specific battery level
- hidden notification icon
- option to detect package installer to prevent its bug (stops mesh activity when you're installing new app and starts it again when it's done)
- new option to dim the screen (useful at night)
- select between two navigation bar overlay modes: fully black and mesh
- probably less memory usage due to better optimalization
- tabbed app UI
- small fixes
- totally no ads
and in the future - things from "TODO" (see at the bottom of this post)
Here's the current status of premium version:
The premium app is ready, but still in beta (some bugs may happen) BUT...
I want this premium version to be paid (not much ofc!) - and making it possible is quite hard in my country (or even impossible in this case...), so I'm talking to my friend from Holland - he can help me with that (by creating the company in Holland, which is necessary to sell the apps). The problem is - we both don't know Holland's language.
Is there anyone from Holland who could help and that I could speak in English with?
I'd love to publish the premium app as far as everything about the company is done.
v1.3.1:
- new option to add the mesh to the navigation bar
- small optimalization
v1.2.1:
- fixed doubled mesh after reboot (black screen)
- fixed unnecessary scrolling to the bottom ad
v1.2:
- quickly show/hide the mesh with notification action
- Ads. Sorry =)
v1.1.1:
- shortcut to the donation page
v1.1:
- new option to automatically start service on boot
- small bugfixes
[TO DO]
- Widget
[KNOWN BUGS]
- I can't install any app (unable to tap Install button)
> This bug is fixed in version 2.0 (added new option to prevent this) - see above
FAQ:
What do I need this for?
- Imagine this situation - your battery level is really low, but you have to search for something important on the Internet. Making the brightness lower often isn't enough. That's when you would need my app - to turn off some count of pixels.
There are lots of apps that dim the screen...?
- This app works different. It doesn't overlay your screen with transparent image (but there is such option in premium version if you need it too). It overlays your screen with totally black screen, which makes some count of pixels off, to prevent them from consuming battery.
Do I really need AMOLED screen?
- The best results you can get right with AMOLED screen, where black pixel means turned off pixel. However, even in other type screens black pixels are saving some battery, so it's just worth to check.
In battery stats I can see that this app consumes a lot of energy. Why?
- Don't look at the stats, look at the real battery consumption. Probably, Android Battery Stats app "thinks", that this app display an image on the screen all the time, because of what it shows an information about consuming energy. In fact, this app turns OFF the pixels (in AMOLED screens with this function), so it SAVES that energy, not consumes.
When the mesh is on, I am unable to install apps (Install button is disabled). What to do?
- That's because of the Android Security. In premium version of Pixel Battery Saver I added an option to bypass this protection. In this free version you can simply turn off the app (by clicking "Turn off" button in Settings window) before installing any app and then turn on it again.
Where's the premium version?
- I will post it to Google Play in some not long time Please see the post #2
May I know the amount of battery saving actually realised by you.
It's hard to specify how much it saved, because there's no option to check it. I just feel that my battery is handling more hours, which is obvious when some pixels are off.
Touch screen doesn't work properly when the service is active(moto g), and some times it make random touches on screen (observed on moto g and galaxy nexus), I couldn't make a screen shot for the random touches as it stopped after a restart on both of my devices but here is a screen shot of how it effect the touch screen on my moto G (developer option "show touches" and "pointer location" was turned on)

Will it help with phones with Super-LCD screens too???
@ahmed.gubara - that's pretty weird. Maybe that's because of non-amoled screen. Don't really know, I have never experienced this and you're probably the first! Maybe try with lower level of the mesh?
@jonytestXD - thanks. As I wrote in FAQ, I know about this and I will fix it someday.
@projektileSAM - I am not able to test my app on every smartphone, so you tell me
thanks guys for using!
App is working with no problems on Samsung Galaxy K Zoom. Not sure when I'd use it since I can only put up with it when I don't need to see detail i.e. simple puzzle games.
@-SAIUN- glad to hear it.
Maybe you should try with the Low or Medium level of the mesh.
And there is really a benefit on battery consumption gaugeable?
Did you measure it, like runtime with and without the app? How much energy does the app use?
See post #5

I will be more than happy yo test it...but you also don't have exact way of knowing, acc to #5, but I will need some parameters or something to post results
Nice work
what are the premium features? are they any?
Of course there are some, but the premium app isn't released yet.
For now what have I done:
- start on specific battery level
- install package detection (fix for disabled "Install" button when installing new apps)
- also Dim the screen (make it more dark)
- no adds
I just have to make sure everything works fine, battery is not draining etc. I don't want to publish not-tested app
New version 1.3.1 is available on Google Play.
Changelog:
- new option to add the mesh to the navigation bar
- small optimalization
I have LG G2 and app is working, when i set lowest i see changes. Will test when i get little % of battery. Tnx
I can't press 'trust this application' on a VPN dialog and 'Install' on an app install screen. Any fix for that? (When I disable this app it works again)
EDIT: Please jump to post 4 for updated test results . Come back to this post for why this thread
There are umpteen threads on battery saving tips / methods and a few on AMOLED screens and battery savings. So why a new thread, could be the Question
Because
1.Battery saving means are meaningful if backed by numbers, else it’s subjective
2.Tests below were done on N7100, but given the popularity of AMOLED (two dozen and counting per Wikipedia), across cell phones and tabs, this may be interest to battery freaks and hence posting in general section rather than N7100 threads
3.Provide a replicable methodology of testing on your AMOLED device (rooted) both manually and automated. There are threads on XDA as well that suggest testing methodology but have not come up with easy testing methods and automating it unless I missed
I am NOT a qualified guy to understand the technical details of testing screen power nor of the methods/ apps used. There is enough material on the net to show how complex it is and savings using using dark screens vary from 18 to 41 %. IMHO, the jury is out and appears to be taking a long break
All I have done is put together various pieces to show a way of testing it and come up with results that are indicative and demonstrate trend lines.
Also the apps chosen for testing is not be misconstrued as canvassing for them.
There may be better ways of doing this test using other apps or better testing ways, which you are welcome to share here.
Test Device Configuration
GT-N7100 (t03g), ROM- Deep Impact (Morph variant) (Kitkat) by @Sammy_052
Kernel Agni- 3.0.101-India-v4.4.2-OC-INTL-STOCK_HYBRID-KitKat
Apps Used for testing
3C Tool Box Pro: Has a nice feature showing screen consumption in mAh (though on devices like mine which don’t have a current sensor, it is derived from battery drain percentage). Plus, it has the advantage of modules that can be accessed and test automated. Immense thanks to @3c , developer, who helped a ton
Darker : Screen Filter that was thoughtfully provided in the ROM. Free version allows darkening up to 50% as used for test
Stay Alive : To keep the screen alive for two hours (being the test duration), since the maximum screen time out is limited to 10 minutes in KitKat. 3C Toolbox offers a way of choosing apps , which keep screen on, as long as apps are kept in foreground. For some reason, this did not work with Nova Launcher as chosen app, hence the need for a different app. There are many free apps on Play Store with similar functionality and may be used after testing that they do not impact 3C
MacroDroid : To automate the test process. This is by @UndeadCretin and is a great tool to automate without a steep learning curve. The aim of click starting the test and getting results in mail box has been achieved (barring manual intervention in the first minute of starting the test) . The macro used for this is posted on the app thread. This macro can be easily tweaked and battery bugs can have a field day trying things like Live wall paper, under volting/over volting and altering CPU / GPU frequencies to see impact on power
Broad test Methodology (details later in thread)
Screen power usage was tested in 3 cases. Cell was kept in airplane mode to get cleaner results (optional) and Stay Alive used to keep the screen on for two hours ( targeting to get a drop of 10% battery level) for each test.
Case 1: Bright wall paper
Case 2: Bright wall paper with screen filter
Case 3: Solid black wall paper
Results of Testing ( files attached )
Case 1: Bright wall paper: Screen consumption is 195 mAh
Case 2: Bright wall paper with screen filter: Screen consumption is 189 mAh
Case 3: Solid black wall paper: Screen consumption is 172 mAh
Conclusions
1. Using a solid black wall paper as compared to bright wall paper shows 11 % savings.
2.Using a screen filter on bright wall paper shows very little savings 3% . Was surprised at this result and repeated the test and the results were practically same. This disputes the accepted belief that screen filters save power but is savings as low as this?
Internet reports savings from 18% to 40% by using black screen as compared to 11 % above, am guessing are due to a bunch of reasons, like testing methods, screen size, age of device, device to device variations, ROM, kernel settings, GPU/CPU voltage and frequency to name a few at device level .At next level, is the apps used, usage pattern of phone, algorithms used for dimming the phone and many more.
Testing as above is not real life. To carry out real life testing, ideally one would need to replicate activites for a fixed duration like calling, texting, browsing, watching stored video, on line music / video. I have not come across any app or way of doing this and would be happy to give it a shot, if someone can suggest a simple way
Detailed Test Instructions - To provide consistent testing environment and get clean results
1.Disable scheduled running of apps during the test and Greenify
2.Set the wall paper which you want to test and ensure sufficient battery
3.Run Stay Alive and use the second icon (red one) in the notification bar
4.Run Darker at your preferred settings for tests with screen filter
5.3C settings ( Thanks to @3c )
a)Settings>Recorder>Continuous recording enabled
b)Settings>Recorder>Time frame and Rate- depending on how long (maximum) you want to test and how frequently you want data to be updated, choose appropriate option . I used 12 hours, 10 minutes
c)Settings>Battery>Monitoring> mA retrieval method (if your device is listed choose, For Samsung devices, on enhanced estimated or estimated on the other side is pretty stable and the same for all devices, but often slower to update.
d)Settings>Battery>Monitoring>Estimate, use estimates drain, or if your device has a current sensor and reliably works choose use current sensor
6.Create shortcuts on home screen for battery statistics module of 3C using 3C widget
7.Start the test and go to markers tab and set the marker. You can create markers from the action bar or from history tab long pressing a record. Markers shows average consumption, be it mA or %/h (tap the value to switch). Min/max shows the range for the % or mV. Remember to show full history (not just % changes) by long-pressing the options and tapping “full history”.
8.Time the test and take screen shot of markers results
9.Repeat test for different cases
Looking forward to your views
Nice
Wow, this is a totally put together review. AmoLED screens save a lot of power on black, unlike LCD backed by light from LED where the entire screen needs to be on at all times when the screen is displaying anything. LED screens do not have a back light to support them in producing light. The individual pixels themselves produce the light. Hence if part of the screen is black, it means that, that part of the screen is off.
I had thought this through when making the rom in the first place and hence was the need in keeping all the elements either complete black or white. But samsung as a company decided to go away from this beautifying and practical aspect and the later phones have begun shipping with rather different set of colors.

Thanks for your view. It is fitting that you as ROM developer, included this aspect in your ROM and that is what triggered me thinking.
The test above is representative of a small portion of SOT, maybe around 10%. Real life usage is what needs to be measured and am searching for an app that can run fair amount of real life use cases. Only Antutu does something similar but requires user intervention to run. Ideal is auto play so that it can be automated through MacroDroid. Your thoughts around this are welcome
Sent from my GT-N7100 using XDA Free mobile app
Updated test results
So, i was stuck for long to do real life testing and it is done now !!!
A few major changes from the previous set up
1. ROM changed to wesam.othman v8 by @wesamothman
2. Better Battery Statistics (BBS) used in place of 3C Tool Box mainly because of ease of setting up and being more popular, eliminating process described in OP. But IMO, 3C Tool Box is far more versatile and powerful in studying battery usage
3. Most importantly, discovered Battery HD app (free) by Small Tech (https://play.google.com/store/apps/details?id=ch.smalltech.battery.free&hl=en). Very hand app and well designed. This app has on line calibration features using wifi browsing, streamning music and video. I wanted to extract these modules and incorporate in the macrodroid macro (part aim of this test is automation as mentioned in OP). Requested the developers and amazingly, they jumped in to help and created separate links for each of these modules so that i could call them in the macro to execute without any manual intervention. Extremely thankful to Santiago and Vadim of the team who made it possible :good:. Without their help, automation of this test could not have been possible. Thanks again !!!
Coming to the test , real life usage to the extent possible has been simulated except for gaming, calling , texts and social media apps. Test consits of 30 minutes of browsing, 15 minutes each of streaming music and video. Screen was kept on during the test duration and darker (screen filter) when used was set to 50%. Pics attached
Results
Case 1: Bright wall paper- Batterydrain was 10 %
Case 2: Bright wall paper with screen filter - Batterydrain was 9%
Case 3: Solid black wall paper - Batterydrain was 8%
So, this may be interpreted as- if you get 5 hours SOT for instance using a bright wall paper , you would have drained 50% of battery. But with using a screen filter on the bright wall paper, after 5 hours you would have used only 45% and the extra 5 % (over usage not using screen filter) would give you additonal 30 minutes of SOT !!!
And if you were using a solid balck wall paper instead, that would have given you an additional hour , making it 6 hours of SOT !!! ( Of course, this is assuming same usage and linear battery drain)
So, it is your choice, you can test it yourself
Happy battery life...cheers
OLED displays gets burn-in almost exclusively in places where there are a lot of elements that stay completely white all the time. Most notoriously, status bar and navbar. For some people who text a lot, I have seen burn-in for the call and video call buttons, as well as individual keyboard letters.
My question is, is there an app, or a theming engine to be precise, that would allow the user to set a time interval, during which those high persistence elements of the picture could be dimmed over time? For example, user unlocks the phone and starts typing a message - navbar, statusbar, keyboard letters are all 100% white. They remain white, then after 60 seconds they start to dim, and after 120 seconds they are at 30% brightness. So when you're having long texting sessions, keys would be dim enough so you can make them out, but since they are not leaving your muscle memory you can type just as well as if it was at 100% brightness - but you save a lot of energy and thus substantially reduce the potential for burn-in. And if you're outdoors and can't make out what the time is after those 180 seconds, you gently pull down the notification bar and it resets to 100%. Something like that.
I can't be the first person to think of this. Moreover, I think AOSP devs realized this at around version 9 and dropped the overall brightness of the status/navbar to 80%, but it remains like that the whole time. What I am proposing would be infinitely more efficient. Anyone here knows something that's able to do that?
Avoid use in direct sunlight. Seconds not minutes if you do. Use manual brightness control and keep below 50%. Typically I comfortable use 30-40% indoors. Excessive brightness prematurely kills AMOLED displays needlessly. Excessive heat with the display on ie again direct sunlight should be avoided.
Use dark mode. The red pixels are longest live, blue the shortest; heavy blue or white usage will degrade the display the fastest.
Use icon packs and layouts that support pixel conservation. Rotate widgets and icons periodically.
This heavily use N10+ has over 8k hours on its display. There is no detectable fading, failed pixels, color inaccuracies, nothing; it remains perfect. It's a mirror image next to my new N10+ with less then 50 hours on it.
AMOLED displays can be very long lived. Everything on this homepage gets rotated slightly from time to time, even the page number icons ie 3 instead of 2.

OLED displays gets burn-in almost exclusively in places where there are a lot of elements that stay completely white all the time. Most notoriously, status bar and navbar. For some people who text a lot, I have seen burn-in for the call and video call buttons, as well as individual keyboard letters.
My question is, is there an app, or a theming engine to be precise, that would allow the user to set a time interval, during which those high persistence elements of the picture could be dimmed over time? For example, user unlocks the phone and starts typing a message - navbar, statusbar, keyboard letters are all 100% white. They remain white, then after 60 seconds they start to dim, and after 120 seconds they are at 30% brightness. So when you're having long texting sessions, keys would be dim enough so you can make them out, but since they are not leaving your muscle memory you can type just as well as if it was at 100% brightness - but you save a lot of energy and thus substantially reduce the potential for burn-in. And if you're outdoors and can't make out what the time is after those 180 seconds, you gently pull down the notification bar and it resets to 100%. Something like that.

I think you could look into immersive mode, It has many different names Another option talk in developer forums fr your phone , otherwise its hidden somwhere in your settings

Is there a way to prevent burn in when using the phone in a bright environment? My job requires a bright environment.

No other than the mods I already mentioned. AMOLEDs have a finite lifespan that's proportionately shorter or longer dependant on brightness level. The brightest stars burn the fastest...
All you can do in that case is use at minimum needed viewing brightness and try to use in shaded areas.
Maybe use a work phone so you don't burn up your personal phone.
I am under the impression that none of you even read what I asked in full. I asked a very precise question regarding a particular way to mitigate burn in, nothing on HOW to to mitigate it, as I hinted in the name of this thread.
1. "Avoid use in direct sunlight." Excuse me? Phones are meant to be used outdoors, and they have been since the birth of the idea of a mobile phone.
2. I don't have a Samsung phone. What I meant was something more universal, like a Magisk module, or a root theme engine.
3. With due respect sir, everything you mentioned is more of a paranoid hassle than an automated instant-fix. What I proposed, on the other hand, is.

Welcome to the planet. The more you run it in direct sunlight the higher the risks including outright failure. That sound better?
This isn't a backlight LCD* or a LED display. OLEDs are less robust than LEDs.
Due respect my mass... prudence isn't paranoia.
8+k hours here and no detectable damage of any kind.
* direct sunlight can fry LCDs too.

Dude, nobody sets their phones to sunbathe for no reason. If the situation requires me, I'm using it the open sun. That hasn't damaged any OLED screen I used in the past 10 years. You ain't gonna convince anyone to rearrange widgets every week giving a meteor strike argument, especially with that attitude. Now please, are we over useless internet forum fights? I'm not negating any technical point you made, and what you did is certainly a way to deal with the issue, but it is objectively not practical for 99% of users.
