99% sure that this will increase your battery life

There are numerous threads about getting better battery life involving different settings, turning on and off stuff manually and battery calibration etc etc but noone that really helped as much as what ive discovered now.
Me and my spouse has the same phone but we dont have the same operator. I have Telia which has the best coverage in this area while she has Telenor which is worse in general coverage making the phone work harder in the net + really bad when it comes to 3G coverage and thus having slow data connection.
Therefore we have very different standby time on our phones and ive tried to tweak it with different kernels, modems and different flashes but nothing that really helped.
So I made a thread to gather some info from various people but it hasnt growed that much yet (http://forum.xda-developers.com/showthread.php?t=989266). 2nd post from "theduckking" showed that he was using an app called "tasker" which cost ~4euro (well worth the money if you have low battery time)
Now ive just started using it but I already have 69hours of standby and 27% left of battery and ive never had that amount of battery standby for a really long time! This is getting close to an old fashioned Nokia 3310 standby
My spouse isnt getting as much obvisually as she has worse coverage which drains more battery but she has gone from barely a day to 2 days standby with 10% battery left ~30hours and this is with the following method.
Note. Both our phones have the same configuration, its only the operator which is the difference
Rom: Darky 9.3 Final
Modem: JPY (its the one coming from the darky 9.3 flash)
Kernel: DamianGTO 1.1 Gold

Now two things that have made the battery last longer is first underclocking it to 800MHz and undervolt -100mV in CWM (this will only make a minor difference albeit noticeble)
And the grand thing that will really up your battery is the app called "TASKER".
Ive only setup two rules and that is to turn off mobile data and wifi when screen is off and turn them back on when screen is on. You can customize it further if you like but im just gonna show how to setup the basics.
After you have downloaded it, fire it up and press "new" and then just press "ok" select "event" and "display off", press "done"
Now press the "+" and "net" then "mobile data", make sure "Off" is selected and then press "Done".
Press "+" again and "net", "Wifi Net" check that it is saying "Disconnect" and press "Done" and press "Done" again to get back to the main menu of "Tasker"
Next rule so press "New" and "ok" again, then "event" and "Display" and select "Display On". Press "Done" and then press the "+" followed by "Net" and "Mobile Data", make sure the checkbox says "On" and press "Done" and you are set. Press home button to apply the settings and you should now have "Tasker" in the top row.
Now this fix will maybe not suit everyone but if you value battery time more than anything then its absolutely for you.
What will happen is that all data traffic will be completely turned off when the phones screen is off and the impact of this is
You wont recieve instant (push) gmail until you unlock your screen
Google talk will not let others see you online/busy when screen is off
If you are making calendar updates from google calendar online, the calendar updates wont appear until you unlock your screen
Probably other stuff that havent crossed my mind

Some screenies from the battery status page in settings.
Sorry about the dark image, I raised the contrast and brightness manually afterwards to make it somewhat readable (I forgot to disable the "screen filter" which I enable at nights when reading )

pretty interesting.. will give it a try..

Hardcore made a thread on how to conserve battery life by disabling hsdpa. You can search for it. It has helped me a lot.

I'm using "superpower" from the market and I will install tasker to see if there is new options

If you use Tasker just for Wi-Fi and data turn - off when screen is off you better use (IMHO) SuperPower app. You also better untick auto retrieve option in MMS settings or you will not receive MMS anymore with this settings.

yay I'm famous... or at least useful
I have my connection Tasks attached to this post. you just have to import them and set up rules when to execute them. I have one that starts the OffOnScreenLock task when the screen is locked, one that calls the reconnect task when the screen is unlocked and one that does call reconnect every 45min
View attachment connectionTasks.zip
experiment with it^^
EDIT:
I also set tasker up to enable and disable GPS automatically (when maps or navigation start it enables GPS, on close it disables it again)
It's fun to play around^^

I using Super Power long time too (although i have 3000 mAh battery ), and i have battry life about 4-5 days on normal using, and 2-3 days by heavy using SGS.
I ask, after your testing, if you can make comparision battery life, using Super Power and Tasker, wich is better ?
Thank you in advance

Same here. Using Super Power some months ago, but now I'm curious about Tasker.
Wonder if it's better thar Super Power. Anyone can confirm that?

I just took a small look at super power. I found nothing you can't do with (except the 2g/3g toggling but I did not try that) tasker. The difference is, that you have to set up your own tasks and functions and rules. you can also create widgets and use variables to alter the way your own task works. If you have some programming skills you will probably love it, otherwise it's lots of potential left unused. (like loops, if/else statements)
You can read up on it over at lifehacker.com

I agree of course. Then again if you are a developer might as well completely roll your own
Tasker is nice if you know how to use it. Doesn't do all the things SuperPower can do, but can do a lot of thing (though less on 2.3, I think ? Not sure).
Gotta decide what's your own cup of tea. Apps like SuperPower (and Juice Defender, and a number of others ones) try to make your life easier, while with apps like Tasker (and the right plugins, of course) you can make your own rules. It's often more difficult than it sounds, though!

[Android 2.2+][11.11.2011][v1.3] CF.lumen (for Chainfire 3D)

THIS APP AND THREAD HAVE BEEN REPLACED BY THIS ONE HERE: http://forum.xda-developers.com/showthread.php?t=2711912
CF.lumen changes the colors of your Android device's display based on the position of the sun. With the default settings, your display will get a warmer tint (lower color temperature) when the sun is down, to look more like indoor lighting and less like the sun, which causes less strain on your eyes and doesn't keep you awake as much.
This is an addon for Chainfire3D, you need to have both Chainfire3D and Chainfire3D Pro installed to be able to use CF.lumen
With the default settings, blue tints will be reduced in brightness when the sun goes down. This reduces how much looking at the screen keeps your brain awake later at night. If you have sleeping problems, you should definitely be using this. Do yourself a favor and install similar software ("f.lux") on your PC as well - it fixed my sleeping cycle.
There is also a full-on sleep mode that runs on a pre-set schedule. By default it shows the entire screen in red, so as to not destroy your night vision when you look at it.
When you want the screen to look normal for a bit (for example for gaming or looking at pictures) simply tap the notification in the notification tray to disable CF.lumen until the next time you turn on the screen.
Additionally, it can also use the light sensor to automagically switch to sleep mode when it is fully dark. HOWEVER, you should be aware that most devices do not have a sensitive enough light sensor to detect the difference between house light and darkness, so this function may not work very well on your device.
Last but not least, a function is also provided to turn off the screen based on proximity sensor activity.

I did have it enabled for about 3 hours before realising that. After that I turned it off. So this probably means it was the sensor services?

Works pretty well, except for that when it's enabled, it seems to somehow turn off the fade screen transition in CM7 when you hit the home key. The screen still correctly shrinks, but once it shrinks it just waits for a split second, then disappears. Normally it shrinks and fades at the same time. This isn't a big deal really but I figured I'd post it here in case I'm not the only one.

Still thinking about how to best do that. In the newer Android versions (Gingerbread and up) you actually HAVE to have that icon to make sure Android doesn't constantly kill the background service.
Alternatives are for example to restart the service on a timer, I think I'll build that in at some point.

CF.lumen updated to v1.2
Changelog:
- "Sleep in the dark" now checks for proximity as well as light levels
- "Bright light" mode added, switches to Day mode in bright light even when in Sundown or Night mode
- "Notification Mode" settings added. Can remove notification. WARNING: Doing so may lead to CF.lumen being shut down by Android at random times.

Can you add the option for the bright light mode to switch to night sundown mode instead of day mode? I'm also seeing 7-8% CPU usage with the proximity sensor enabled. I like the idea of this feature for battery savings (example, putting the phone in my pocket and having the screen turn off immediately) so if there is any way to tweak the battery consumption it would be great! Would you be able to have the icon displayed change to reflect the mode it's in? For example a sun for daytime, moon for sunset mode, etc.?
One last thing, noticed that the Sleep filter setting does not get saved with version 1.1. It says Unknown even after you have selected a filter.

v1.3
Minor bugfix release v1.3:
- Minor crash fixes
- Current color filter display no longer says "Unknown"
- CPU usage reduced
- Power usage reduced

[HOW-TO][NEWBIE GUIDE] Optimize & proper set up your Galaxy S6 Edge (stock firmware)

[HOW-TO][NEWBIE GUIDE] Optimize & proper set up your Galaxy S6 Edge (stock firmware)
As I've read across this forum and on several specific threads related to usage, battery life and so on, as well as discussing with some of my friends having a S6 or S6 Edge, I realized that most of the people don't really know how to properly set up their phones or how to use them efficiently.
OK, I get it, this is a fancy phone, not every owner is a developer or tech guy so it might be that many choose it based on the looks and don't really know how to optimize it...then they start complaining about different things like lag or battery drain not knowing that most of the problems are caused by miss-usage or improper setup. Of course there are bugs too, nothing is perfect. Of course there are many firmwares available and some are market or carrier dependent so some features or settings might be missing from some of them or even work differently.
What I will try here is to provide some guidelines and tips for setting up various things on the phone in order to maximize it's battery life and for a better usage. I will also make some recommendations based on my experience, tests and usage that might not apply to everyone. Use common sense and logic to apply similar settings in your particular case. Don't come screaming that you made that or that and now something is not working.
And YES, I know there are similar guides like this posted over the Internet and I'll probably make similar recommendations here too but I couldn't find such a guide here on XDA that is particular to this phone (if there is a better one than you might as well ignore mine).
All these things I'll describe below are applicable to any STOCK, NON-ROOTED 5.1.1 firmware and won't break warranty or your phone.
Now that was a long (and maybe unneeded introduction) but I thought to write this for everyone...let's start.
Model No.: SM-G925F
Android: 5.1.1 r2 (LMY47X)
Baseband: G925FXXU2QOI7
Kernel: 3.10.61-5672012
Build date: Fri Sept 4 2015
Carrier: Orange RO
DISPLAY
First I would like to say some words about the display. We have a great display, high resolution and it is most likely the biggest battery drain factor. There are two major things about it that you should keep in mind and will help you to get a better battery:
1. It's AMOLED...that means that the black pixels on it will consume no power because are not lit. Studies showed that even if not completely black, AMOLED displays use less energy if the displayed picture is darker compared to a lighter one.
2. The brightness level. Most people use it on "auto" or high level settings and this will be a major drain factor.
You can drastically lower the battery drain caused by your screen by selecting as much as possible dark (black) backgrounds and/or themes. There are some nice ones available in the Theme Store (my favorite is the Dalkomm Coffee Theme), that make most screens and menus dark/black. Also choosing a dark wallpaper for lockscreen/homescreens will help.
Don't use screen brightness at maximum...never. You don't need that in 99% of the cases. Also you won't probably need the automatic setting either since most of the people are spending most of the time indoors (either at work or home). A low manual setting will be fine most of the time, I have it set up at about 20% and only need a brighter one when going out. At that time I just tap on "auto" and it'll increase based on ambient light level. So you don't even need to tweak it alot every time. Find a low manual setting that's fine for your eyes and just tap on "auto" when you go out in sunlight.
CONNECTIVITY
Another battery drain factor is your multiple connection/radios features. In most cases you use just several: Mobile Data, WiFi, GPS/location and BT (when applicable). That means you should turn off all the others you don't use...NFC or BT (when not connected to a headset or car-kit or not listening to music). I don't listen to music and don't have a BT headset so I mostly not using BT (just when I'm in my car) and almost never use NFC so I have both disabled and I enable them only when needed via the Quick Settings.
WiFi
WiFi should also be properly setup otherwise it'll have impact on battery. It was incorrectly assumed or considered that keeping WiFi on all the time will drain battery faster. That was proven in different tests that's not true and in fact keeping WiFi on all the time won't make a big difference and in some cases was even better than to turn it off/on. I think is something similar with the car engines that suck more fuel when started that when running at idle. The major power drain is not when WiFi is running while is not connected to any network, but when the WiFi radio is powered up. When is on and not connected, it's going into a lower power state so the battery consumption is negligible.
I had a case with one of my friends that had WiFi setup to turn off when display was off...wrong choice, he got about 30% battery drain overnight because instead of having it connected to his home WiFi, the phone was using his 4G/LTE connection to make all the background sync/updates. That was eating his battery and also his data plan. After setting WiFi to "always" his overnight drain lowered to as little as 2-3%.
In some regions/carriers there are 2 other settings that were proven to help battery life: WiFi calling and VoLTE. I don't have either of them but based on different articles and what people say, they surely help with that so don't forget to turn them off if you don't use these features.
You might also want to try turning off "Always allows scanning" and "Smart network switch". I have the second turned off but I keep on the first one. Basically the first option tell the Location service to use WiFi for locating the device even if WiFi is switched off (by the on/off switch) so that means the radio is active. Second option should make you switch faster from WiFi to mobile data in case the WiFi signal is not strong enough or fluctuating. In my country there are plenty of WiFi hot-spots and they have mostly good connections so I don't use this feature.
GPS
Well here the opinions are split but I am currently having it ON all the time and Location Service is set to "high accuracy". I personally haven't noticed such a major difference with or without it so I preferred to let it on as it is used by many apps or services. You can try to set Location to "wifi and cell only" but don't think that will bring you a major benefit.
RUNNING APPS/PROCESSES
Well this is an important one. I've initially started to turn off/disable/uninstall everything I don't need or use. This can be done mostly from the Settings - Applications - Application Manager or if you want to go further, you can install Package Disabler Pro from PlayStore, about which I'll detail later.
Now why we should do that? There are lots of apps, processes and background services running on our devices that take care about all the things we do on the device. The problem is that ALL are using resources: processor time, memory, space and so on. In the end these are translated for a user in LAG or battery drain. Of course we cannot kill everything and I learned long time ago that installing Task or memory managers on Android it's the worst thing you can do. Android it's smart enough to take care better about it's resources and processes (at least to a certain point) and keep killing a certain process won't give you more battery life but will eat more of it in the end,
What I wanted to say is you shouldn't start disabling, killing or blocking everything cause you might end up with an unstable or not properly working phone (case in which only a factory reset might help). First of all look at the ALL tab in Application Manager and try to identify what you don't need or use. For example I'm certainly not using some things like: music, books, news feeds, Samsung's keyboard (I use SwiftKey), the TouchWiz launcher (I use Nova), health services or whatever, S-Voice, S-Health, S-Finder, I don't have any smartwatches so I don't use any Gear processes, fancy device wake-up functions (like wave gestures) or animated wallpapers either.
So after all considerations above, you decided that you can safely disable some apps/processes. All good but you'll quickly learn that some of them cannot be disabled via Application Manager (the "disable" button is grayed out). Now what? Well here comes handy that Package Disabler Pro that I've told you about in the beginning. That app is able to disable ANY apps/processes on your phone, including those that are protected and cannot be disabled via the normal way (and yes it can do that without being rooted). The downside of it is that you must be careful what you choose to disable not to have something that is needed for the normal functionality or the apps you're currently using. The app has also a backup/restore function (via an xml file) for saving the list with apps you have disabled and easily import them back after a factory reset for ex. I've added to this thread my list of disabled apps as it is exported by the application (just unzip and copy the file on the root of your internal memory and it can then be imported in the Package Disabler app)
Another important thing is WHAT apps you're using. I know that socializing and social networking are some of today's most trendy things but keep in mind that some of the apps used for that are not so well made. An example could be the Facebook app/messenger which are reported to drain alot of battery. RSS feeds, news feeds, multiple weather apps or widgets, all contribute to battery drain and lag. Don't install several apps/widgets for the same purpose (like several calendar apps or weather apps). Each will take resources and won't have an added value. Want to use another weather app/widget than the one coming with the phone? Fine, install it...but don't forget to uninstall/disable the built in one or others that do the same thing. Same goes for keyboard for ex; I use SwiftKey for years and got used with it. For me it's better than any keyboard that Samsung might put on the device, therefore I've disabled the standard Samsung keyboard. I also don't like TouchWiz launcher and use Nova that offers me much more flexibility so...I've disabled both the "easy" and "regular" TouchWiz launchers. I went to the point that I've even disabled the different embedded font types, you have 5 of them and I doubt someone uses more than one at a time.
So as you all can see it's not only a matter of setup but also a matter of usage. When you have a device you have to use it properly otherwise it'll not perform as you expect. Imagine a car that has a manufacturer fuel consumption value of 5.5 liters/100 Km....that's under certain conditions not on ANY type of driving. Fly with 200+ km/hr on a highway and I'll guarantee you won't have 5.5 liters/100 km consumption. That doesn't mean the manufacturer has lied or mislead you. Same goes with a phone, if you don't know how to use it and optimize it, you'll have a bad experience.
I work in the IT industry for years and I mostly laugh when I hear someone advising somebody to reinstall the operating system to solve a problem. Same goes for "factory reset" for a phone. Yes, this method works some times but that won't solve the root cause of an issues if you're using it the same way. After several days it'll perform as bad as before and you'll just say that "factory reset" did nothing. Of course it didn't...YOU have to do something different, not the phone.
Now I apologize for the long post and I do hope that at least some will learn to better manage their devices and to understand what they're doing not just running certain commands or procedures blind. Both S6 and S6e are great devices but we should learn how to properly use them in order to benefit the most from them...otherwise we just come here asking for help or mumbling about what crap devices they are.

Thank you, I will check to see if I get an improvement on the standby battery drain.

Your part about not setting the screen to Auto is flawed. You mention that we are mostly indoors, and you don't need a brighter screen for that. Auto mode also knows that and sets the brightness lower. It already does automatically what you do manually.

Tnx. And yes....keeping screen at 20% brightness and just switching to auto when in outdoors works great for the battery life.

Not quite, I've tested it. If you're on "auto" and use a lower setting on the slidebar, in a dark room the screen is too dark, you'll have to turn off "auto" and the manual brighteness set on the same level will be much higher than on auto.
Now if you have such good eyes and you're able to use "auto" in all cases with the slider at 20% that's good for you...unfortunately I am not so that's why I use it as I've described. The point is that "auto" mode consumes MORE battery regardless of how it's set, than a lower 'manual' mode. So I preffer to have it like this than to use auto all the time.

Thanks for the awesome guide. I'll start disabling some useless processes and see how my battery life is working. Anyway without much editing the battery of S6Edge is pretty good. I can use it a whole day and still 19% remaining. As a comparison I wasn't able to do it with my S3 having to recharge it 2 or even 3 times at day.
Again, thanks for the guide!

How can I prevent my J5 screen from dimming ???

Hi all,
I know this is an old question, but all my googling thru online forums led to nothing conclusive yet, other than non-working suggestions or using apps. But having to live with this dimming thing is bothering and exhausting !!! Simply said, there aren't any useful settings. Max display timeout in my phone is 10 minutes but, no matter which value I pick, after some seconds my display gets dimmed. And the developer option "stay awake" serves no purposes aswell... it just prevents the screen from going to sleep completely when under charge, but still dims after few seconds of inactivity. Is there any trick to finally turn this infamous auto-dimming off ?? IF I CAN, I would like to achieve this result WITHOUT using any apps, if possible. Oh my J5 is rooted of course, I can even tamper with system scripts or variables, if u instruct me on how to do.
Thanks !

On my J5 screen never gets dimmed unless the display is turning off due the timeout.
There are apps which can dim the screen, including apps which "save battery". Maybe you have a kind of this app which does this?
Your screen turn off after 10 minutes or after the screen gets dimmed?

It seems a very common and complained issue between Android users from what I read here and there, so more a wanted feature by the original developers than a rom bug... not sure if u are referring to Android version, it is 5.1.1 Kernel id 3.10.49-787809.
No of course I haven't any energy saver apps installed or such things.
All system energy saving options are disabled already.
My phone dims the screen after abt 10 seconds, no matter how long I set the timeout

Decrease Brightness more and more Tip popularity: ultra Works: how not!
You'll understand this more when you'll read the next 2 tips! Decrease your screen's brightness and install an app to go even further. Also, enable auto brightness at minimum. It's ok saving power but it isn't if this means having a black screen

Black Themes Tip popularity: high Works: of course
This device features an AMOLED display.
If you didn't know, this technology gives you true black by shutting down the pixels on your screen!
Given this, you're actually saving power when your device is displaying pure black

Grayscale Display Tip popularity: medium Works: possibly
By setting your device in grayscale mode you're removing colors (wow) and since our device still features that AMOLED technology you're more likely to save power because of darker colors forcing pixels to be almost black.
Don't think you're really shutting down the RGB leds! In fact you're lighting up them all, but with decreased brightness. This won't work well if you use apps with bright/white themes!
It could also save power because of the less data to process(not confirmed)

Disable Always On Display Tip popularity: medium Works: yes Explained by: Nikx97
You can't use AOD for long. That's true and Samsung knew why (other than marketing purposes) when our community asked louly for having it on our device.
Behind that, our display is different from the one mounted on s7.
What's different then?
Our display requires the cpu to be awake everytime, updating the screen or not, because there's no memory this display could use to just keep showing an image. From s7 and later, there's this memory that gets updated by the cpu every minute.
This surely ends up with a huge drain

Enable UPSM if you really need it Tip popularity: medium Works: of course
If your phone isn't rooted (I'd ask why are you even here) it will set up for you a black theme and set your device in grayscale mode, while decreasing brightness and disabling most apps. Then is up to you disabling wifi, bluetooth and setting it in airplane mode. I'd rather shut down my phone directly in this particular case

Don't play intensive games Tip popularity: Ultra Works: overkill
If you're not playing games your CPU will be grateful to you and your battery too. There's not much to be explained.
Of course you can still play games. Just try to prefer simple ones instead of PUBG Fortnite Asphalt 9 The Sims Minecraft Gta Online etc

Set up your CPU governors Tip popularity: suggested only by developers Works: Overkill if set properly
First of all for this you'll probably need a good kernel. Not necessarily a battery kernel, a fairly customizable one would fit nicely (If you're using an S7 Edge battery and you're on Android 7.0, feel free to try my kernel, ask for LKernel here).
Here are the best settings from what I've tried so far (I'm going to explain also why)
You'll need to set (perhaps with the aid of Kernel Adiutor or MTweaks) POWERSAVE governor for LITTLE and CONSERVATIVE for BIG.
The aim of this is to force LITTLE to work more than BIG, because it uses less power and it is enough for off screen processes and whatsapp, telegram and also some games (such as 1010 or sudoku or 2048). If you want to go further with this configuration limit your frequencies: the lowest you can to 600/800mhz for LITTLE and the lowest to 1800mhz for BIG.
With this configuration, when LITTLE can't handle some tasks BIG comes in rescue and solves the problem.
Lazily but it does his work and, of course, use less power.
It is advisable going further with kernel adiutor's settings to save more battery. I'm probably going to post my settings file later
