More control. More battery. More comfort.
Lumos is fully customizable automatic backlight level changer developed as a complete replacement for stock HTC auto-backlight service. A wide range of HTC branded devices is supported starting from HTC Diamond/Touch Pro up to the current WM flagship HD2.
Lumos focuses on minimal CPU usage, maximum battery saving, low memory footprint while maintaining maximum backlight change smoothness and responsiveness. Lumos combines the best from all available auto-backlight solutions and adds many extras for your tweaking needs
Features:
- simple and clean installation and uninstalation
- extremely low CPU usage when working, 0.05-0.3% on polling
- NO battery and CPU overhead (drainage) unless you actively use your device's display
- low memory profile considering all the options
- simple and reliable configuration GUI with easy step-by-step calibration process
- many options that let you change every aspect of how your backlight works
- program exceptions to set different backlight for any application
- relative excaptions allow you to amplify/attenuate the automatic backlight for specific applications
- ability to force display ALWAYS ON for certain application
- integrated tool to detect all active application names, leave it running in the background and it will log all application names you use
- configuration failsafe. No matter what you do, Lumos won't crash, just tell you what is wrong and use defaults.
- supports vast majority of HTC branded devices since HTC Diamond
- many supported languages
Just install the CAB, start LumosWizard from programs or soft reset and you're all set!
- Lumos always installs to the device (no matter what you chose)
- Installer will create auto-start entry (Lumos will start after a soft-reset)
- Installer will create a shortcut to LumosWizard in your programs
- should any problem arise after first installation, try to soft-reset your device before consulting our FAQ below
Program installs to \Program Files\Lumos\
Lumos.exe = starts/stops auto backlight service, accepts commandline switches
LumosWizard.exe = graphical tool to configure all aspects of Lumos
settings.txt = configuration file is not included in the package, it will be automatically generated by LumosWizard after successful calibration, you can edit it manually in your PC or by using LumosWizard, text edits in device are probably no longer possible because of unicode encoding.
LumosStarter.exe = (re)starts Lumos service without any visual feedback (used for startup after soft-reset and for special issues)
TROUBLESHOOTING:
You can take these simple steps to troubleshoot any problem, perform both steps and if your device reacts differently than described try fixes marked ">" one by one starting from the top. Please restart your device before you start, your problem might fix itself.
1) Run LumosWizard, start Calibration and proceed to second step (max sensor), Lumos should report positive values as you move the device near to light source.
> move the damn finger! xD
> another application exclusively locked the sensor, try to disable other apps using light sensor
> sensor drivers or sensor SDK is missing, try if different application like G-Light works, report the problem if it does, update your ROM if it doesn't
> your sensor may be defective, try some 100% compatible ROM like Energy just in case and consider RMA if unsuccessful
2) Run LumosWizard, start Calibration and proceed to third step (minimum and maximum backlight setting). The backlight should actually change as a preview when you move the slider.
> check if windows built-in auto backlight is disabled in power settings
> another application may be forcing the backlight level, try to soft reset and disable other apps that can change backlight level or manage backlight in user profiles
> original HTC backlight utility DLLs may be missing in certain early WM6.5 ROMs, try to install BacklightHotfix.CAB attached to this post and reboot. If it just won't work, try another program like G-light, if you're still out of luck, try to contact your ROM chef about this.

FAQ:
What exactly is the calibration for, backlight is still the same after calibration?
The calibration ensures Lumos can detect the detection range of your light sensor properly and lets you set minimum and maximum possible backlight easily.
It has 4 steps:
1) Minimum value the sensor can read (probably 0 on all devices)
2) Maximum value the sensor can read (expect this to be something around 1400), you need to use a light bulb tor this step.
3) Minimum brightness you want. Lumos will calculate everything with minimum value reported by your device, but it will not let the backlight go below this value. (like if you want to have backlight 2 in shade because 1 is too dark for you)
4) Maximum brightness you want. Lumos will calculate everything with maximum value reported by your device, but it will not let the backlight go above this value. (You may notice that backlight level 7 and 10 is a little difference and can be both read in direct light, however if you limit the maximum to only 7 here, you will save a lot of battery)
5) After you are done with the calibration, you can review your setting on the settings tab and click 'Apply+Save' to exit LumosWizard and actually start Lumos service. There is no auto-backlight while the configuration Wizard is open, it defaults at level 6!
How program exceptions work?
- Switch to the Windows tab and start for example TomTom, leave TT and click it's name in the window list, then specify the backlight you want for this app and tap Add.
- If you disable "Exc. for active window only" on settings tab, you need to specify exact window name and exception will be triggered even for inactive application (minimized for example).
- If you activate "Exc. for active window only" on settings tab, you only need to specify part of the window name in exception settings (useful in case part of the window name changes). If the window name is "AdobeReader - document.pdf", only add exception "AdobeReader -". Be aware enabling this option increases CPU requirements of Lumos by about 20% (means roughly 0.06% total for slow diamonds).
Note that you will probably need to enable "Exc. for active window only" on settings tab for exceptions to work on WM6.5.
How to set a program exception step by step?
1. run lumos wizard
2. switch to the tab "windows" (the last one) and let the wizard run in background
3. run your program(s) you want to add
4. close the program(s)
5. switch back to lumos wizard -- voila, all the window names you visited are there!
6. tap the program name you want in the window list, it will switch you to the "exceptions" tab and fill the form for you
7. set the backlight level you want (1-10) and tap add to exceptions
What is a Relative Exception?
- relative exception does not force one specific level but rather amplifies and attenuates normal auto-backlight behaviour for the application in question.
Consider this scenario:
Code:
- my allowed backlight ranges in levels 2-7
- I want to use a navigation app in car and it is kind of difficult to see on sunlight, shades in car would read for level 3 or 4 and that is not bright enough
- I can either create an exception and force backlight all the way to 7, but that might not be optimal on battery
- therefore I create a Relative Exception of +2
- for the navigation application if the backlight would normally be set to 3 by Lumos, it will be amplified by two to 5. What would normally be level 6 will get amplified to 7, since that is my maximum level.
- You can also use negative values in Relative Exception to decrease the backlight for certain app by certain amount to save battery for example.
How backlight modes work?
- Backlight modes are individual equations used to determine proper backlight level from current sensor value.
- Linear - this mode is equally sensitive in dark and light environment.
- Root - this mode is more sensitive in dark environment and is best suitable for human eye and therefore default.
- Quadratic - this mode is more sensitive in light environment.
- Custom - this mode features customizable graph, you can draw a graph yourself with stylus or click on the blue area under each level number to input border sensor value manually.
Levels outside your min-max boundaries are hidden.
- Note that using custom mode do not affect CPU requirements in any way.
Commandline switches?
- There are 4 switches that can be used
"+" will increase backlight by one
"-" will decrease backlight by one
"s" will run normal Lumos operation without restart prompt after +/- tasks are completed
"q" will quit Lumos after +/- tasks are completed
Example to increase backlight by 3 and disable automatic:
Code:
"...iles/Lumos.exe" +++q
My *insert a game using G-sensor* is lagging strangely, can I fix it?
- guys from HTC thought it would be a cool idea to tie all sensors together in a framework, unfortunatelly it appears that when one program locks a sensor for read, other sensors may get locked as well on some devices. There is only one solution that will de-lag such game - not to use the sensor while it runs.
- Create a non-relative exception for the game in question and your lag should go away.
Backlight is not changing at all, it's the same all the time?
1) go to Start - Settings - System tab - Power - Backlight tab and DISABLE the 'Auto adjust backlight' feature.
2) close the configuration Wizard with "Save+Apply" button, auto-backlight service is disabled when you are configuring Lumos or when there is no configuration specified.
Program won't start at all?
You NEED .NET 3.5 Compact Framework Redistributable. It is faster and more stable and offers more stuff for developers than the 2.0 you probably have. It is rumored it may even make your device work faster (or at least .NET based apps).
Download it HERE (only about 3MB on device, don't be scared by the installer size as it contains support for more processors)

NOTES:
Please disregard the hacks from previous versions and always set your sensor minimum and maximum to real values (0-xxxx)! Some sensors might have different minimum than 0 - this is a hardware defect and you need to use the defected value for Lumos to work correctly.

To admit it, I haven't installed it yet, but I'm tempted. Just one question which might also be of interest for others:
What's the advantage of your app compared with G-Light?
And not to forget:
Thank you for your work! I still find it amazing that many xda-devs are building programs for free just for a "thank you" by the community.

Well I tried G-Light and LevelSight but will only compare it to G-Light as LevelSight does things a bit differently IMO. I set G light to 3s polling interval to make the comparsion accurate. I don't like to put dirt on someone elses app, G-Light is a fine piece of software and I encourage the developer to implement some of my ideas to match mine and make it even better
- G-Light can behave competely unpredictably, it pumps up the backlight when you're in shade (this is because of the luminosity spikes)
- Lumos eliminates any spikes by the 4-read interpolation keeping your backlight more comfortable and smooth
- Lumos uses a tolerance which further prevents the backlight to unexpectedly changing (and causing a CPU spike)
-G-light rarely reaches below 1% of CPU usage (1-7%usage is common) which can drain your battery as a side effect
- Lumos rarely crosses above 0.5% CPU usage on default settings (0.05-3% usage is common) (NOTE: this will even improve in future versions)
- in G-Light You cannot change how fast the luminance values are read from sensors, they are read on change = further battery drain. You can only change how often to set backlight
- In Lumos you can set sensor read interval and backlight change in its multiplies to save CPU and power while retaining smoothness.
- Memory usage: GLightRunner 595.43KB , Lumos 311.53KB (but this will get a bit more later)
- No noticable memory leak in either applicaiton
- G-Light has a frontend app to set up
- Lumos has none yet but you can change the configuration file
- Neither Lumos nor GLightRunner can be completely shut down without using task manager (Lumos will once it has frontend GUI).
- G-Light can exclude applications
- Lumos can't yet
-G-Light settings is pretty much still limited compared to Lumos
To sum up it's definitely worth trying

Thank you for your long and precise answer, You definitely convinced me!
I'll try it right away!

Lumos v02
Lumos Version 02 has been released, all the changes are logged as (!) in the bug tracker above.
Default settings response time is shorten to 2s, while CPU usage is pretty much the same as v01 with 3s refresh.
Memory usage: 339.53KB
CPU usage: 0.05-0.25% on scan, 3.15% on backlight change
Power consumption is 2mA better than v01
If you want to achieve more sensitivity of backlight transition without CPU overhead, set tolerance to 0 (CPU usage bug is fixed now).
Configuration file is now idiot-proof, program will tell you what is wrong on syntax/logical error
EDIT: 02b contains one more bugfix, the auto backlight range cap finally works 100%
Enjoy

Quick question; does you app let the backlight go to 0% in full darkness, like LevelSight?

Yes it in fact goes to 1 (backlight disable) as lowest on default. You may want to increase it to 2 in the config file if it's too dark for you.
The point of this app is YOU set how it should behave, there are virtually no limitations unless you enter a complete nonsense to the config. And even then the program should just notify you about the incorrect settings and not crash, so don't worry and edit!
The program needs to be restarted in order to apply new settings. Either kill it via process/task manager or soft reset if you don't have one. Note that this acts like a program, it won't start again automatically if you kill it or soft reset. And also it won't store anything in your registry or enywhere else on the device, so it's perfectly safe to "just try". I will make a manager app later that will let you setup and control this underlying process.
But FIRST we need to make sure the service is bug free and does everything we need before I even start building the front-end app
Also you may share your custom settings you find best with me and if it's performing well I can select that one as default for future.

Thank you Niker! V2 is working great for me. Only one thing:
The lightlevel changes linear as you've explained and that's basically working fine (and much more smoothly than G-Light for example). But it tends to get to dark. I've now changed the minimum setting to "3" to get the average backlight-level I prefer. BUT: I like to read late at night in bed and it would than be nice to have the backlight at level "1". So would it be possible to exclude light level 1 & 2 from the linear alignment and to only use those levels if it's "really dark"?

PS
Just to give you a bit more information about my personal preferences and what I want to achieve:
I actually like the default HTC auto-backlight. It more tends to bright than to dark backlight and it's making the level changes very smoothly so you almost don't notice them.
The only thing i don't like about it is that the minimum level is hardcoded to level 3 which is too bright for me when I read in bed with no additional light in the room.
Of course those are my personal preferences and that of course doesn't necessarily mean that your app is meant to handle that way!

Well I have an idea, I wonder if .NET CF 3.5 supports external scripting as the PC version does. Basically that might allow you to replace the backlight algoritm without compiling the program yourself. You could quite easily make exceptions binded to really low lumen values or time of day with just 2-3 lines of code.
EDIT: I fear this is not possible, System.CodeDom.Compiler is awfully stripped down, I would have to make up my own scripting language for this to work and that would be very difficult.
But I think I can add this as a setting to the configuration file.
DIM_TO_MINIMUM_BELOW = 0
- disabled (default)
DIM_TO_MINIMUM_BELOW = 25
- below 25/750 lumens
very simple and I think this would do about what you want
Expect this in the new version.

Thank you mate, I really appreciate it!

Thanks for your suggestions.
Lumos v02c is out, it contains your 2 desired options (for backlight 1 and 2 separately). You will however be disappointed by the sensitivity of raphael sensor, it reports 0 like all the time.
This change theoretically lets you set lumen values for the 2 lowest values manually and once the sensor reads larger values, the MIN/MAX_BACKLIGHT kicks in. It's possible to have 4-8 auto and dim to 1 or 2 on low light, so you can kinda simulate the behaviour of LevelSight if you want to.
Oh and as the cherry on top I disabled tolerance by default, for more smoothness, the impact on CPU and battery should be minimal < 0.05%
The next version should include a tool to easily restart Lumos to apply settings, it will be needed for the graphical user interface later.
Enjoy

Major version released:
Lumos v03
- all bugs connected with dynamic backlight should be fixed now
- changing settings.txt is even safer (program should never crash, just tell you where is problem and use defaults)
- includes LumosKiller.exe that can start/restart/shutdown Lumos easily
In case no bugs are found until friday, I will start building GUI.

Could you integrate special brightness normally only used when starting the camera? You'd probably need to debug the camera application to find out about the special ICOTLs for that. I did that with my Magician back in the days.

Program-specific exceptions will be added after the GUI is done, I still need to figure out how to list running windows by name. If you have any experience with this using C# or C++ I'd be happy if you PM me, but I guess uncle google knows how to do this, just refuses to share it with me right now

Uz to testujem, zatial to vali krasne a v pohode ;-)
I just wrote that I'm currently testing it, no problems so far.
Thank you and please keep up the good work ;-)

Great application Nik3r!!
i like so much, because don´t touch my registry, It´s light,and also have minimal resources consumption
But, i need your help with the configuration file,
i have htc diamond, and the battery of this device drain fast
how can set the settings to obtain best battery duration?
Thanks a lot!!

You can increase the polling interval, enable some tolerance and lower the maximum brightness.
Try to make these changes:
MIN_BACKLIGHT = 1
MAX_BACKLIGHT = 6
POLLING_INTERVAL = 1500
EXTRA_POLLS_BEFORE_SET = 1
BACKLIGHT_TOLERANCE = 1
set minimum backlight to whatever is reasonably visible in shade
.. this will set your polling interval to 1,5s and make your brightness change every 3s instead of 2. The tolerance prevents brightness changess less than 2 units. It's the brightness change that eats most CPU (up to 3% spike) and thus battery and the tolerance makes sure it's not changing until a larger change is required.
And make sure you killed the old v01/02x version or soft reset before using 03 because older versions can't be killed by LumosKiller and two of them running may ruin your battery.
... hmm by the way I wonder why I didn't call it "Nox" instead of LumosKiller (any similarity with HP books is completely unintentional )
Good luck

Thanks for your quick and detailed reply!! i did those changes you suggest,
I´m really fan of your app!!

2 methods for turning off softkeys, if doesn't work on your device try the other one, and if both doesn't work please contact me.

Wow. I love the concept.
I didn't have a chance to check out the whole video (youtube was acting up), but does this have the ability to automatically dim the screen to a specified level based on what application I have open? For example, could I set it to automatically dim my screen to the lowest setting when I have my bank app open?
That would probably make this worthwhile.

this is nice.,thanks ^_^ i will purchased this..

wow great idea, you are the best

Version 1.2 is out:
Added Tasker/Locale plugin !

thanks alot for posting, keep it up, you're doing great!

I just purchased the app. I like it, especially for the Tasker integration.
I was using the other 'Screen Filter' app for a while but it was
having full brightness flicker issues when I would have Tasker change
the filter % from one value to another. This was incredibly annoying.
I do have a MAJOR request though that I believe would help me truly
appreciate my purchase. The primary reason I use these filters is to
attempt to black out my AMOLED screen.....unfortunately, your Total
Screen Filter app maxes the filter at 94.12%. This is a huge problem
for me. Furthermore, your competitor (Screen Filter by haxor industry)
allows for dimming the screen even further then your app (they allow
for 2% filter....which is what you call 98% in your app....almost
pitch black).
I'm an optical engineer and work in extreme dark rooms alot. Sometimes NO VISIBLE LIGHT can be on in these rooms
while experiments are running...sometimes a very small amount is
acceptable.
So my DESPERATE plea for a feature request:
Allow for users to push the filter further beyond 94.12%....ideally a
full 100% black out. Because honestly, 94.12% is not enough at all for
my purposes. At least allow for a 98% filter so you can be equivalent
to your competitor's capabilities (which is a free app I might add).
I can understand your concerns with allowing this ability (people
unknowingly blacking out their screens). So maybe making it a
non-default ability would work perfectly. I use these filters with
Tasker and have it setup so I can easily remove the screen blackout
under particular conditions. Please help me out here. This ability
would really make me happy.

full 100% black out. Because honestly, 94.12% is not enough at all for
my purposes. At least allow for a 98% filter so you can be equivalent
to your competitor's capabilities (which is a free app I might add).
I can understand your concerns with allowing this ability (people
unknowingly blacking out their screens). So maybe making it a
non-default ability would work perfectly. I use these filters with
Tasker and have it setup so I can easily remove the screen blackout
under particular conditions. Please help me out here. This ability
would really make me happy.

Note 4 Battery life improvement

Powersaving / extend battery life
On rooted and non-rooted Note 4 devices.
There are quite a few battery saving tools on the playstore market. However, most of these tools only use what your device can already do by itself. Besides that, it is one more app that can and will consume power so the overall effect of these apps is very limited.
Here is a lot of stuff you can do by yourself to save power and increase battery life. Although most forum users will already have some knowledge on the way your phone works I will begin this post with the most obvious tips on power saving.
Obviously, the list below is a list of possibilities, and not a list of stuff you should do immediately while reading this post. Just look carefully which functions you really use which you don’t. Every option can save a little bit of battery, but together they make quite a difference.
I am quite a heavy user and at this point my phone can do 1,5 to 2 full days without a charge.
General:
1 Turn your GPS of if you are not using it
2 Turn your Wifi of when not using it
3 Turn your Bluetooth of when… (you get the idea)
4 Same goes for NFC
System settings:
Display and wallpaper:
Use auto brightness and set it to your liking. There 10 different levels of auto brightness. I have found that level 2 or 3 is not only sufficient but friendlier to my eyes.
If you really want to get most out of your battery, it’s possible to have a completely black wallpaper image. Black doesn’t take any power so this will save you a lot during a full day of work. I always have one black wallpaper in my preferred wallpaper list.
Smart stay. With smart stay on, the device will stay on while looking at it. Now you can reduce the screen time out mode to 15 seconds. Actually works pretty well and saves a lot of power.
Activate auto adjust screen tone.
Turn daydream off.
Turn led indicator off.
Touch key light duration on “always off” or 1,5 seconds.
Increase touch sensitivity off.
Lockscreen:
It really helps if your lock screen just has a black wallpaper.
Unless you really need to, don’t make your screen lock too complicated. The fingerprint scanner seems pretty cool but really isn’t. It often takes several swipes to get it to work and that takes power as well.
Personally I use non at home and a simple pattern outside. I use the tasker app to automate this but I will talk some more about specific apps after the general settings.
Multiwindow:
Although the multi-window function is one of the things that makes the Note series the king of Phablets, a lot of users hardly ever use these functions. If you are one of these users, turn this function off. The hone keeps checking which apps you can or can’t use in this function evertime you open an app, or open your recent apps. This takes power and CPU.
Even if you are a multi window user, the 2 listed options:
Open in split screen view & pop up view shortcut aren’t used by many. If you don’t use them, turn them off.
S pen:
Same thing here, look at the options You really use during the day.
I do find Air command a very useful function and personally I always keep it on. If you don’t use it, you know what to do by now.
Under Air view there are the following options to turn off if not used by you:
Information preview / Preview info, extend text, or enlarge pictures hovering over them
Icon Labels / View the labels of icon by hovering over them
List scrolling / Scroll up or down by holding the pen over the edge of the screen
Link preview / Hovering over a link will show you a preview of the page
Air menu / Hover the pen over the action or attach button to add content or contacts
Motions and gestures:
Again. Turn everything off that you are not using.
Direct call / By bringing the phone to your ear it will call the contact on the screen
Smart alert / Device will vibrate when you pick it up to notify you about missed calls and messages
Mute/pause / I don’t think this option will affect your battery life
Palm swipe to capture / I have no idea who thought this would be a good option to add. Turn it off if you agree.
Cloud:
I have rooted and installed ROMS and apps on many phones of friends. What seems odd to me is that most people have at least 3 cloud storage spaces were the automatically store all their pictures. Some them even had 4 or 5 without realizing.
1 Samsung account,
2 Picasa / google,
3 Dropbox.
One of these will do just fine. You can have more but just don’t let them auto-upload your camera pics. If every picture you take has to upload to 3 or more different cloud spaces, your device will be working more than it should have to.
Backup data:
Same story. Pick one. Stick to it. Don’t have 3 backup accounts.
Accessibility:
Vision and hearing / Turn off unless you need them
Dexterity and interaction :
• Assistant menu / Off
• Air wake up / Off
• Press and hold delay / 0.5 seconds
• Interaction control / Off
Direct access / Off
Answering / ending calls / Look at what suits you best. Picking up quickly will save battery over the phone ringing longer.
Powersaving:
Whats in a name ha? The powersaving mode can be adjusted which means you can get to saave power in the way you find most efficient.
The options are:
1 Restrict background data.
• This option limits the stuff you can do on your phone rather drastically. Dowloading content, viewing multi media and sending messages. Personally I never use this as this makes my phone just as useless as a phone with an empty battery 
2 Restrict performance, which has 4 sub options:
• 1 CPU performance / This machine has enough power to do pretty much everything with this option on except for some high performance games perhaps.
• 2 Screen output / Usefull to have turned on when in need of extra battery life.
• 3 Turn off touch key light / Usefull to do when needing power.
• 4 Turn of GPS / Which I already only turn on when needed.
3 Grayscale Mode
• This option doesn’t affect your performance but just makes you entire phone black and white. This grayscale mode saves a lot of power and you will still be able to do all the work stuff like browsing, mailing, texting, etc…
Ultra power saving mode:
In this mode your phone can last for several days but its use is very limited. You can browse the web, call and text but that’s pretty much it.
I think this would come in very handy if the end off the world has come, all power is gone, and you want to be the very last person to send a text 
Just kidding. If this is what gets you home on a few percent of power, it comes in very handy.
Look at the standby time when you turn it on. It’s amazing how long a phone can last in this mode.
Widget use:
Widgets can save or cost you power. There are very useful widgets that give you quick access to wifi, GPS, Bluetooth and other power saving stuff on your home screen. Besides easy access you will become more awre of the fact that you have a lot of stuff on that really doesn’t need to ben on at the moment.
Other widgets can cost you lots of power and data. This mainly depends on the amount of data the widget has to download and the refresh interval. For example: If you have a Facebook widget on one of your home screens that refreshes every 15 minutes, that means it will go and download new content from facebook every 15 minutes. This costs you data (when not on Wifi), but also battery life.
So look carefully at the widgets you use before installing them on your homescreens if you want your battery to last.
Launchers and home screens:
By organizing your favorite and most used applications you will be able to open them faster and so it will shorten your screen on time.
Personally, I think you should be able to open every app within 2 seconds. If you have many apps, and the only way to open them is scrolling to several pages of app drawer, your doing something wrong.
The beauty of Android is the fact that it is the most customizable system out there so use it! Combine widgets, apps, shortcuts, and folders until you have everything within reach.
When using TouchWizz launcher, it really helps to turn of Briefing on your home screen. This makes the phone slower and it costs battery life and data usage.
Many Samsung users have come to terms with the fact that TouchWizz will never be the best launcher out there (And that’s the understatement of the [email protected]&1ng century).
That’s why most heavy users will install a third party launcher as a home screen replacement. The one most used is probably Nova Launcher.
Playstore link:
https://play.google.com/store/apps/details?id=com.teslacoilsw.launcher
Youtube tutorial:
https://www.youtube.com/watch?v=sO52dfFm40o
I have found after installing this launcher and setting it up, my battery life increased with 7-9% on a full days use. At this point I haven’t figured out if this is only because I navigate more efficiently, or that there are other reasons aswel.
The benefit of a third party launcher is more customization for your home screens and app drawer (such as making categories is the app drawer and such). But also to have gesture control, for example: Have apps open when swipning up or down, with one or multiple finger, double tap, home button and so on.
This gives you much easier and faster acces to your most used apps.
Other usefull apps for powersaving:
Tasker is an app that lets you automate tasks on your phone. For example letting your phone detect when you are at home, and automatically turn on wifi, turn of GPS and your lockscreen pattern.
Tasker does not have to let GPS run for these task and can also turn everything around when you leave home. The amount options on tasker is pretty much unlimited and these automated tasks can save a lot of power thus increasing battery-life .
Playstore link:
https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm
Youtube tutorial(s):
https://www.youtube.com/watch?v=EzY9te12UI0&list=PLjV3HijScGMynGvjJrvNNd5Q9pPy255dL
Tasker is not an easy to use in 2 minutes app. It will take some time and effort to really get into it, but beside winning a lot of battery life, it will let you automate pretty much anything you can think of.
Rooted users:
For rooted users there are many more options to save power and increase battery life.
I am just going to mention a couple:
• Limiting your CPU frequency. Your note 4 has a surplus of power and you will never need it all unless you play high performance games. You can limit the frequency completely, or make profiles that change the frequency as your battery level decreases. Personally I use the app SetCPU to do this.
Playstore link:
https://play.google.com/store/apps/details?id=com.mhuang.overclocking
• Freezing or uninstalling bloatware. A lot of stuff on your android phone you will never use. I always use Chrome as my browser so I won’t keep the original browser Samsung gave me on my phone. This goes for many apps. I use 2 applications to freeze and/or uninstall apps from my phone to free up memory, RAM and save battery life:
SD Maid (also limited functions for non rooted users)
https://play.google.com/store/apps/details?id=eu.thedarken.sdm
Titanium Backup (also the best backup app I have found sofar)
https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup
Both these apps let you freeze and uninstall bloatware. Be carefull though! Do not just start deleting everything that doesn’t look familiar, or you will get in trouble.
Freeze apps first and see if ervything keeps working. Then make sure you do a Nandroid backup within TWRP or CWM recovery before definitely uninstalling apps.
There are several lists available on the web which show what can possibly be frozen and/or deleted. This is one I found quite useful:
http://www.reddit.com/r/galaxynote4/comments/2pgiib/the_ultimate_list_of_removablefreezable_bloatware/
Custom ROMs:
There are many custom ROMs that are more friendly for your battery then the stock firmware. However, if you are new to rooting and installing custom ROMS please be carefull and watch the tutorials before you start flashing away.
A good site to begin is:

Thanks man.
I have the CPU set on 1728 MHz without any lag or problems even with multitasking. Only when playing games I push it up to the max.
At this moment I use 2 ROMs:
Alliance V2.2: This one is most customizable and you'll keep all the touchwizz functions. (I do recommend a third party launcher like NOVA or Action Launcher 3 to get rid of the lag TW still has).
CM12 official: This is more friendly to your battery, but you'll have to install CM Spen addon and Note buddy or Spen control to get some Spen functions working. The latest nightlies hardly have any bugs (I haven't experienced any).

I don't really play games so I am alright with 1728
I was actually wondering how does CM works with S Pen thank you for the info I will definitely try both of them

Can you explain how to change the auto brightness level? All I see is the "auto" checkbox and that's it. No way to adjust the auto brightness level. I can adjust the brightness manually though, but that isn't "auto".

When pulling down your notifications, you'll see a slider and a checbox as you can see see in thee pic below. (It might look different becausse I'm running Alliancerom).
If the checkbox is ticked, you can adjust the slider for different levels of autobrightness. Without the checkbox ticked, you change the screen brightness directly.

I'm on stock and with Auto checked, it becomes unchecked when you adjust the slider. Thus, adjusting the slider only forces it into manual brightness.
Edit: and I'm on the n910a

Didn't know that. Did not spend much time on stock. Sorry....

Nothing like that happens on the snapdragon one. And i can bet it shouldn't happen on Exynos as well. This feature has been the same for years, and has worked very well; there is no reason to change it on any variant now.
Recheck that your rom is not messed up.

My firmware is via ATT OTA, so it isn't messed up. I can't even flash anything since the n910a isn't rootable. The way my brightness slider is now is also how it was on Kitkat, and all ATT models are like mine.
It's just that when you mentioned the different auto brightness levels, I thought that maybe there was something I was overlooking in my settings. Apparently not, since your type of autobrightness was apparently adjusted by ATT.

Yup, must be ATT setup, although it makes much more sense the default android way.
Wonder why they decided to change it

My battery life on my note 4 is truly awful and I genuinely have no idea what's doing it, without fail it'll die like half way through the day when I only really use it for reddit and WhatsApp, I've heard by a lot of people that snapchat is really bad for battery. Whenever I look at these battery apps they never seem to tell me though, my screen on time is always atrocious and everyone else is getting like 6 hours, I use alxedandr rom btw, I also get lags here and there and I have no idea why can anyone help

Most people are having problems with Google Play services drain. It's causing poor battery life because it's stopping the phone from deep sleeping. Sign out of Google Play in the accounts page in settings, then reboot the phone and sign back in again. Uncheck all the items you don't want to sync for Google.

I'm on lollipop and did a cache wipe straight after installing AND uninstalled the Facebook app. I've got 40% remaining after 12.5 hours. Boc3 seems to be really stable.

If you are having problems with battery drain I suggest you go to settings>application manager>running and kill tasks from there.
I am getting exceptional battery life on my Exynos

just quickly, is there any way to like reset the battery life physically?
ie in the old days, we would often let the battery run flat out, and recharge fully and run flat out a couple times.
and it'll basically give you the best longest battery life after doing this.

I think I just discovered a fix after updating to 5.0, I am running stock just for the info, all I did was boot into recovery and wipe cashe partition about 3-4 times and that seemed to have worked very well battery life is back to normal. Can someone who has this problem confirm?

What was your previous battery usage like for heavy, moderate and low usage?

It was strangely very bad after I updated to stock 5.0, I would lose about 2% every 15min I mean very bad to the point that I was about to do a factory reset.

KK only
For those who cannot identify the battery drain source from the battery setting, disable your alarm clock. The stock alarm clock is causing a huge drain, and it hides itself in the Android System. Not even wake detector could detect it. I did a search, but couldn't find anyone talking about it. My SOT drops by an hour with the alarm clock on.

Themes / Apps / Mods Notification LED workaround with Always on Display

Hi Friends,
Notification LED has always been a must have for me, since it allows a very quick / non intrusive / non disturbing / ... way to be notified.
But this kind of feature has became very rare, and actually almost absent from 99% of the recent phones.
The main workarounds around there are leveraging AMOLED, by displaying a kind of LED (icon, point, notch circle, ...) above the lockscreen.
This is very nice, but has major caveats : the phone is never allowed to go into deep sleep, leading to huge battery drain.
I've tested plenty of these, and they are all logically plagued with that very drawback.
Using AoD could be a solution, since native AoD is hardware optimized and doesn't cause huge battery drain.
But there is another drawback, at least on my Realme 8 with UI 11 : AoD displays at least the clock, and is always moving to prevent screen burn.
This is cool, but render very difficult to quickly see if there is any notification pending ...
So the best solution would be to only activate AoD when there is a pending notification.
There is many tuto available here and there to do that with any task automation app, but all are pointing "System.aod_mode" setting.
If you have tested this solution, you should have seen that this setting does nothing on Realme phones (at least 8).
After some digging, I've found the correct setting : Secure.Setting_AodSwitchEnable (1 = ON / 0 = OFF)
You may have to make some tweaking to grant your app the right permissions to write it, but it eventually works.

Is not there any free app that do that? mimics an blinking LED with some notification arrives?
that is very usefull even if we have the "allways on" option enabled..
Best Regards,
LPC
