[Q] Certain app questions?

I'm looking for an app that helps kinda show off the S-pen for the Note 3 whether it's games or features. I also am looking for an app that helps stop all services or apps that aren't necessary to run the device when I turn the screen off. Something just to save battery ya know?

All the apps that feature the S Pen come preinstalled, I haven't found any games that will show it off or really benefit from its use however that doesn't mean there isn't one. There are similar non-Samsung note taking apps that have handwriting mode which allows you to use the S Pen but nothing really special other than MindBoard.
As for battery Greenify is a great app management app. With root and Xposed framework you can greenify system apps. Basically this is a hibernating app that allows you to hibernate apps at command or automatically with various settings based on your needs. The free version doesn't require root or Xposed, and the paid version is only a dollar or two. I would recommend this over a task manager/killer because it works around Android's behavior of restarting apps that get force closed.

[Guide] How to Keep Android System Drain Minimal - Battery Life Boost

Good Day all,
I have benefitted greatly from Google and XDA. So I thought I would provide a consolidated way of saving our battery's grace from Android System demonic drain.
I am running Euphoria with Furnace, and I had loads of Gapps installed.
I tried multiple attempts over a 3 days period and did many researches back and forth. And it came down to these few main culprits:
1. Android Location Services
2. Google Play Services
3. Qualcomm Location Services
4. Google Now Launcher
5. Unwanted Sync
Tools I have used to assist in this matter.
1. Disable Service - here
2. Greenify
3. Privacy Guard (should be in built in most custom roms)
4. Titanium Backup
Basically the highest causing drain came from Google Play Services and Qualcomm Location Services. These items persistently wakes the phone up and runs on the background. Using greenify on there further cause issues as greenify tries to hibernate these services over and over again, making this a self-made draining routine.
I followed this thread on Google Play Services drain fix and used the Privacy Guard to perform those tricks. I ran through ALL Google Related Apps and as long as "Keep Awake", "Wake up" or "Auto Start" is enabled, I disabled them. I also look through apps I suspect were waking phone up by looking at the last activation of those events (Keep Awake, Wake Up, Auto Start).
Next I followed this thread on Guide to disable google play internal services using Disable Service app. I also took the opportunity to look at both 3rd party apps and system apps to see if there are services that could be disabled. I disabled Apex Notifier as I realize I didn't needed its service.
Then the next sneaky culprit was the Qualcomm Location Services. Even though I froze them with Titanium Backup, they persist in the system. So making a backup of them, I uninstalled them completely. Hasn't caused me any issue with GPS or Maps. They are namely, com.qualcomm.location and com.qualcomm.services.location. Both appeared as LocationServices 1.0 on Titanium Backup.
I went ahead to Greenify many Google Apps, namely Google App, Google Play Store, Google Services Framework, Google+. I also Greenify many apps that Greenify suggested would slow system down or appear to run in the background which I have no use for.
Lastly I uninstalled Google Now Launcher as it was persistently coming up as alternative home launcher even though I froze it. And I also went through settings of apps to make sure sync were turn off. I only kept Calender and Contacts and Gmail Sync on.
Now I have reduced Android System from 34% to 2% and increased my SOT from 2++ hours to 4++ hours at least. Not an out of earth SOT, but I believe that's decent.
Hope I helped and I wish you all the best in your endeavour to reduce Android System Drain. Cheers.

Thanks bro
Will try and give feedback asap

Suscribed, Rated, and Thanked.
I didn't had time to do any research on this, and this thread appeared on the right time.
Thanks

It should be found in settings page, "Privacy".

I know that this guide is meant for CM based ROMs but I said to myself "ehh, what the hell" and I tried it on my Cloudy 2.2 and the results were horrible. Had to fully charge my device twice in order to go through 22 hours and a total of 2h of screen on time which consisted mostly of browsing and messaging. Wakelock Detector told me that the device was mostly asleep and everything was normal in the Batter Usage menu. Usually I get around 18-20h on a full charge with 2,5-3h SoT. Maybe the locations tweeks were not liked by my Tasker app and caused a huge battery drain, although it didn't appear that much as a wakelock trigger.
I am wondering if the problem was caused by Tasker or the stock ROM itself, but badly I do not have the time now to tweak around and I am reverting back to my previous configuration.

Try using GSam battery monitor to find out the real culprit. I used that to boil down to the final two irritants - Qualcomm LocationServices.

Really enjoying the app.

Nexus 6P Utility Apps?

I just received my Nexus 6P and absolutely love it.
I am wondering if any of you have had good experiences with any utility/tool apps for this device. Apps such as Greenify, CM Cleaner, etc. are a couple I've heard of and was curious if these are helpful or not.
Thanks!

I don't use any utility apps so my response is probably not what you're looking for. There's not really a need for Greenify anymore since Marshmallow introduced Doze unless you want Aggressive Doze mode found in Greenify -- which is again unnecessary if you're using Android N Developer Preview which features an aggressive Doze mode.
Not sure too much on CM Cleaner, but if I had to use one I'd probably use CCleaner since I use it frequently on the PC and it works really well. If you choose to not use a cleaner, someone on here or Reddit reported clearing your cache every-so-often from Settings > Storage & USB > Cached data is useful and may even improve battery life.

Synapse - for use with AK kernel.
Naptime and Servicely by Franco are both nice apps.
Recently by chainfire helps keep recent apps section from being over crowded and adds some extra features.
Then you have the more common stuff you likely already use like "better battery stats", "adaway", " afwall+",.... Not sure about greenify on Marshmallow, I believe the Doze feature built into android does something similar to all apps, but do not quote me on that as I don't really know how how they work, just greenify put apps to sleep and then google calls it doze which is just another word for sleep.

+1 to the not necessary argument.

Get viper4android to improve your audio. Ex Kernel Manager is also pretty awesome. Otherwise explore and see what fits your needs!

You definitely don't need anything like CM Cleaner, those things are total rubbish, they use more resources than they claim to save. Doze is pretty good at getting the device to sleep when it isn't in use, but some people still use Greenify. I use BetterBatteryStats to monitor to power consumption, f.lux to automatically adjust screen temp at night, Faster GPS to aid in getting a quick GPS lock, and Flashfire for flashing certain things when I absolutely need to on the go.

I use All in One Toolbox to control the myriad of aggressive apps that feel they should launch/run everything i start my phone.

Thanks for the replies guys!
I plan on rooting the 6P today, and I have had experience with such apps as SetCPU, Rom Toolbox, etc. But that has probably been about 2 years ago.
What are the go-to root apps for stock android (not sure I'm ready for ROMs yet)?

1. Flashfire, very powerful tool for flashing things (especially useful for taking OTAs when rooted).
2. Ampere Measures current going in while charging, (pretty useful when my fast charger broke).
3. Naptime , improves standby time immensely (Doze on screen off).
4. Faster GPS, much faster GPS lock as I dont really like leaving location on all the time.
5. BetterBatteryStats, huge info on power consumption.
6. F.lux, (Changes colour temperature based on location and sunsets, warmer colours after sunset, less obtrusive to the eyes.
7. Adaway, gets rid of ads ... yay
8. Viper4Android, best EQ and FX processor available.

Ho to get your battery life back.

Dear OP2 friends,
HUGE DISCLAIMER:
Below setup works for MY use and needs. If you are like me it will work for you too, if not go find information somewhere else and don't complain "I cannot get the same results" or things like that. It takes common sense and experience to achieve and understand below info. If you don't have common sense, I pity you, if you don't have experience it's OK. If you are polite and follow the XDA rules I don't mind answering your well structured questions, and maybe others don't mind too, there are a lot more experienced people on XDA than me.
If your question is related to any of the apps/threads mentioned below, please go to that (app) thread, that's why I have put the info right there, one click away.
battery life is something we all want to be endless, well we can't have that, but at least we can improve it from a certain point.
This is what I have been doing for the past weeks and the results are incredible, that's why I decided to share them.
First of all sharing this information is ambiguous because it's somewhat device and user dependent especially how people use it and what apps are installed.
I know that but I believe with the right approach you can get the same results as me, hopefully even better, on the OP2 and possibly other device as well.
I have 148 apps installed at the moment and sometimes even more than 200. If you control your apps properly there is no limit to the amount of apps installed related to battery life.
There are numerous threads on improving battery life out there already so please check out those threads first.
Extreme battery threads:
https://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
https://forum.xda-developers.com/android/general/guide-0-0-hour-idle-battery-drain-stock-t2973588
You can also post your BBS logs there, please don't do that in this thread as I will not investigate them.
Most useful info is already out there so I would appreciate it to go look there first before cluttering this thread. If not I will close this thread.
Let's get started:
improving battery life on Android is (unfortunately) always a combination of things, there is no 1-push button (yet).
In this case I use the following:
- privacy guard (baked in almost any Nougat ROM)
- custom kernel (I use Boeffla: original thread here, I use the Linaro version from ZaneZam)
- Greenify (original thread here)
- Wakelock blocker (built in ROM) + WakeBlock app (optional, original thread here)
- Alarm Blocker (built in ROM)
- Doze apps
- BetterBatteryStats (for finding your excessive wakelocks, thread here)
Obviously you have to be rooted to implement all of this.
The ROM of my choice is RR unofficial.
I like it because of the functionality and features but I believe any ROM with the above features should be able to achieve the same results.
Speaking of results, below screenshots are from my last cycle before writing this thread. One charge got me almost through 3 full days (66 hours).
I fully charged in the afternoon, got through the evening and the first night, then got through the full second day and night, then got through another full day and night and charged only again in the next morning.
If your still following, those are 66 hours of straight juice...
EXPLANATION: There is ALWAYS a tradeoff between SOT (screen on time) and how long your battery will last in one cycle. On my below cycle you can see that I have "only" 4 hours of SOT but almost 3 days of battery life. That is light usage.
If I would use my phone more (more SOT) the battery life cycle would have been significantly shorter. If you complain to me that you "only" have 24hrs of battery life but you show me a SOT of 7-8 hours, I would consider that great battery life! It's all relative...
I have never used one battery cycle from 100% to 0% in one go so I don't know the max SOT I would get with my setup. I would guess around 6.5-9 hours depending on the activity (gaming <=> ebook reading, mobile data <=> wifi, ...). It's all relative...
The screenshots in the bottom of the post might bring clarity for you.
See the following posts for more explanation.
Thanks to:
@nicesoni_ash
@Lord Boeffla
@ZaneZam

@ssrij @The Peterle

Privacy Guard:
*setting things up wrong without thinking straight can delay notifications or not execute certain tasks*
I enable this for all user apps because I don't want any app keeping the system awake. I even have this enabled for some system apps like:
Calendar storage
Google play services
Google play store
Google app
cLock
I mostly disable all locations (if it's not a location dependent app), keep awake, run in background and even start at boot (if the app doesn't need to start on boot) toggles.
Again, use your common sense to figure out if a app needs to run on boot (for example, youtube doesn't need to run on boot, tasker does for starting up along with the system boot).
obviously some system apps need to run in the background for example cLock or calendar storage otherwise your weather and calendar will not update...
You can also configure all the apps on a gradual basis. You let the privacy guard as is on clean install an if you see excessive wakelocks from a certain app, you start blocking it one by one.

Custom kernel:
I use Boeffla config app with always the latest version of his kernel compiled by ZaneZam (Linaro 6 version).
The latest as of the time writing this thread is LOS14.1-beta14 in combination with config app 2.4.34.
I use profile IMPULSE TUNED V3.0, no lags, good performance and crazy battery life.
Screenshots of my minor changes, the rest is identical to the stock IMPULSE TUNED V3.0 profile.

Greenify:
*setting things up wrong without thinking straight can delay notifications or not execute certain tasks*
I Greenify a lot of apps, as much as I can basically, even system apps.
I cannot give too much advice on this part so please go to the Greenify thread to ask related questions. For me it's mostly a hit and miss and right now my config is a big hit.
If you want to know if you can Greenify a particular app you can ask me.
Configuration below in screenshots.

Wakelock Blocker (+ WakeBlock app):
*setting things up wrong without thinking straight can delay notifications or not execute certain tasks*
I personally think this feature is essential in getting good battery life so I'm glad it's integrated in the ROM of my choice (since we don't have xposed yet).
In combination with the WakeBlock app it basically works like Amplify on Xposed, but ROM integrated.
This part is the hardest to explain because it's different for most users. On the screenshots below you can find most of my blocked wakelocks (without losing functionality).
The procedure to block wakelocks is the same as all the other parts explained above and below:
Let your system run for some hours/days (essential!).
After that, trough BBS you can find your excessive wakelocks and through wakelock blocker you can block them completely. If you don't want to completely block the wakelocks you can use the WakeBlock app to put a timer like in Amplify for Xposed, for example I want wakelock x to run every 9999 milliseconds....

Alarm blocker:
*setting things up wrong without thinking straight can delay notifications or not execute certain tasks*
Another essential feature for keeping your device under control.
I block a lot of alarms (without losing functionality) so get ready...

Doze apps:
I use Force Doze from the Playstore to put my device in Doze mode as soon as the screen goes off.
Naptime is an alternative but I find it to generate too many wakelocks (sometimes up to 19 per hour).
I might change this app once in a while if there are better alternatives that come up.
Anyway Force Doze will work for now.

reserved. will add some advices.

Lesser wakelocks means not necessarily lesser drain, good example is definitely the very first lines from this Thread of an old friend from galaxy s3 lte times, he implemented microG on his device and achieved lesser wakelocks but no significant impact on his battery life(see here), what I want to point out is that this equation (more wakelocks - more battery drain) isn't so simple unfortunately, even if true for most of the time, regarding to franco's naptime, I personally made very good experience with this app in combination with his custom kernel, I think especially in this combination it's absolutely recommended..
Furthermore some inspiration about battery life a wonderful guide with plenty of useful information, the absolute majority is generally valid, so don't get confused by the i9305 tag...

Good point Sam, that's why I always say check BBS first if it's actually a wakelock, then treat it properly (disable or time-lapse it).

Guide for hunting down wakelocks and battery drain (No Root)

I've posted this guide on reddit already, but thought it might be useful here as well. A lot of users promote intense usage of package disablers to reduce battery drain, but this is not required to such an insane extend.
---
After experimenting with my S8 for 2-3 months now, I've collected some data and constructed some basic idea on how to fight wakelocks without having to root your device. I'll try to lay down everything here under a few categories.
First of all, I'll say that I tried using my S8 with a package disabler with hundreds of apps and services disabled, and also tried using it with no package disabler at all. I did not see a significant difference. It's too hard to determine if there is one, but I have to note that disabling TOO MUCH can actually hurt your battery usage.
Finally, I settled on using the device with a disabler again, only this time I disabled things strategically after some investigation with battery stats measurement and wakelock detection.
The apps I used were:
BK Package Disabler + BK Plugin
Better Battery Stats or GSam
These are paid apps, but I am happy with what they can do. BK can be replaced with another disabler (as long as it gives you control over individual package services) and BBS can be replaced with GSam Battery Stats, which is free.
General tips on using these apps:
BBS will require your device to have USB debugging enabled, so that you can connect the phone to your PC and unlock the permission manually. You need an ADB command prompt to do that, and you need to give it the following permission with the following command (read more here).
Code:
adb -d shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS
You can use BBS if you do not restart your phone while testing. If you do, it will wipe stats and likely not activate for another few hours, or until you charge again.
You should be using BBS to observe Deep Sleep percentage in the Summary tab (which should be above 95% when the phone is left in idle mode for hours), and Partial Wakelocks to find individual wakelocks that come from apps. Kernel wakelocks are hardly ever something you can do anything about and shouldn't be observed too much, no point in that unless you are rooted. The highest kernel wakelocks should be the ones related to your screen-on time - they are easy to point out as their awake time equals your screen on time.
BK Package disabler, or any other disabler for that matter, WILL require admin privileges to work on your device, so keep that in mind.
BK Package disabler should be used in tandem with BBS, only once you have found wakelocks and/or managed to understand which service is the actual cause. I will give examples below.
---
So, let's start.
Google Play Services battery drain
This one really sucks and it seems to plague any Android device at some point. Most often than not, this problem will occur after you do a system update without doing a factory reset. Last time it occurred on my S8 was right after I did the AQI7 update, after having very good idle drain previous to updating.
What to do in this case?
Log out of your Google account(s).
Enroll for Google Play Services BETA. To enroll, scroll down on this page and find the beta button OR Find Play services in your App list, and do "Uninstall updates", then update it right after that.
Turn off your phone and then boot it in recovery mode (Hold volume up + bixby key, then also hold power button) and select Wipe Cache - This will erase Dalvik cache.
Reboot the phone and delete system cache from the Storage settings
Log back into your Google account(s).
Charge your device and then observe idle drain overnight, or over a few hours.
If this process does not help your problem at all, you might have to do a factory reset to cure the services issue, or the problem might be related to something else, like a google service from some particular app. Use BBS to investigate wakelocks as you check your idle drain.
If this process helps you, but you see the issue again in future without changing anything, try going to the Developer Settings, look for active processes, and find Google Play services. Open them and then hit 'STOP' for each of their sub-services. Don't worry, they will restart on their own. After doing this, you might reboot your phone as well. Last time this little chore helped me out and the drain went away.
---
General Wakelocks
It's normal to get wakelocks even on a perfect system, but BBS will show exact percentages on each of them. Normal wakelocks usually show 0-1% of awake time for a session. If you start seeing numbers like 3%, 7% , 9%, or more, on some specific wakelock, then there is definitely a problem.
Wakelock battery drain will usually appear in your Android System/OS drain stats, so it's impossible to determine without an app.
The most common wakelocks for me are:
- *net_scheduler* wakelock - this one can be related to your WiFi connection. In order to fix it you should have access to the router's settings, and that is not always possible. If you do have access, you can try changing the Wi-Fi channel (choose channel based on Channel Width, for example 40Hz width on 2.4GHz network could use channel 11), and Beacon Interval (set the interval to the highest possible). I found this helped in my case. This wakelock can also be related to google play services - check the previous part of the post on how to possibly resolve the GPS issue. Also, the wakelock can appear under the icons of other apps, when there is little you can do to track down exactly why it happens.
- *com.google.android.gms.measurement* wakelock - this is a VERY common one in my case, and BBS usually shows it comes from Google Services, but always has a specific app icon next to it. In order to resolve this wakelock I had to do the following:
Open my package disabler and go through each app that might be using background data, or the app that is shown next to that wakelock, and then open their lists of individual services. I searched for:
1. AppMeasurementService
2. AppMeasurementJobService
3. Firebase... any service starting with Firebase in its name
These services are related to apps collecting some usage statistics on how you use them and sending them back somewhere, probably the app vendors. You do not need them for any app to be functional, and many apps don't have them. For some reason they can keep your device awake for long periods of time. I disabled them on ALL apps I could find them in and it seemed to resolve a lot of wakelocks after investigating the next following days. This process was probably one of the things that helped me the most with hunting down daily wakelocks as the drain is very stable for me now. For example, today I came back from work with 20 hours of phone usage since charge, almost 1h of SoT and 75% battery left. Other days, I have come back from home with 10 hours of usage, 1.5h of SoT and ~60%. I've seen a lot of improvement lately after doing all of the suggested things and keeping Google services at bay in parallel to that.
---
Bluetooth wakelock
This one was the most inexplicable to me. I never use Bluetooth, or turn it ON for any reason at all. I could not understand why the wakelock occurs.
Ultimately, my solution was to completely disable the Bluetooth System package and all services in it through the BK disabler.
I know this solution doesn't sound good to anyone, but at the same time it might be useful if you also do not use BT at all.
I plan to buy BT headphones in the near future and will be re-enabling this, and at that point I will start observing the behavior of the package once again and maybe turn it on/off at will if the wakelock re-appears too often.
---
Other wakelocks
The general rule here still applies. First, you record your usage with BBS. Then you note down which wakelocks appear on top, and google them as best as you can. Search is your friend here, as the wakelocks are endless and it is impossible for me to list them all and give solutions for even a small percentage of them. Sometimes you might get lucky and find an easy fix. In other times, there will be no easy explanation, or no explanation at all. Such is the nature of Android.
In some cases the wakelocks might be specific services that you can disable for specific apps. In other cases, they will be too general and it will be unclear why they occur. For example, I sometimes get *net_scheduler* wakelock with the Viber app, that can last for 20-30 minutes at random times, and still have not found a way to resolve that, other than uninstalling Viber completely (which is not a bad idea but sadly some of my contacts insist on using that crap. Telegram is your friend).

General Tips:
Use an AMOLED black theme. System theme from Samsung Themes (!) and individual app themes / status bar from Substratum. Do not use overlays for the system UNLESS you do not use samsung themes. I found out that Samsung themes do a better job at painting all system apps black, while some substratum overlays miss a few things. It will also be a LOT less painful to update overlays as you uninstall all of them and re-install them, because using Samsung for the system means less packages from Substratum to be installed. REMEMBER to always uninstall system overlays and statusbar overlays (ALL overlays if you want to be super safe) before doing a system update! Otherwise you can soft-brick your device.
Use auto-brightness and make sure to make it as low as you are comfortable with in rooms that you stay often in (like your own room, your office room, etc). Smart auto-brightness will remember you preference and you will hardly ever use more brightness than you need.
Turn off notifications for any apps that are not essential to you. In fact, I have turned off everything except Gmail, because I have a habit of checking my phone very often and do not miss out on anything, while notifications have become a bit annoying to me anyway.
Put almost all of your apps to 'Always Sleeping' in the device optimization app.
Do NOT always sleep apps that you need to be awake, like your Messaging app, Home Launcher, utility stuff like Navbar Apps, Keyboard. Put those in the 'Unmonitored' category instead.
DE-OPTIMIZE your fingerprint scanner from battery optimization settings if you are having issues with waking up the device with it. It is optimized by default if I remember correctly.
If you are feeling BRAVE, you can do your own investigation for each app that you use often to look for any services that might look like Analytics services. Experiment at your own risk, but generally such services are always a benefit to turn OFF for both battery and privacy reasons.
---
Overall, that's it. If I remember something, I will update the thread. Hopefully this can help someone.
In my personal results, I've managed to achieve a 0.3% idle drain per hour with Wi-Fi active during a test of 12 hours of standby. As visible in the screenshot, the Wi-Fi signal is not even perfect.
Here is an example of idle drain with about 1h 10m of SoT at the time it was taken.

The "Service Disabler" functionality has been removed from the latest app version due to Google Play policies.
Fortunately we can find the previous apk version in the developers website.

hey thanks a ton for this article! My battery is horrible...REALLY. 2 h ost...I've just completed the first part. please explaind better what do you mean with "sign out from Google accounts" step by step. and in my case BBS was not adb enabled...I was not able to see wakelocks. the command explained here https://alexus.org/howto/better-battery-stats-no-root/amp (the google play store version) granted permissions for me. maybe you want to update the guide! I'll let you know how it goes.
cheers

@brokich
Could you please point us exactly to what are the main apps with AppMeasurement and Firebase services?
Until now I have found only the Google play store app.
Thanks for your great guide.

Thanks for the guide. Starting to debug battery issues. Meanwhile tried setting up the black theme. What do you mean by installing only Samsung theme? Do you mean a specific theme made by Samsung electronics or any black theme from Samsung theme market?

Here are the correct adb commands to BBS, as shown in the app in first start:
adb -d shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS
adb -d shell pm grant com.asksven.betterbatterystats android.permission.DUMP
adb -d shell pm grant com.asksven.betterbatterystats android.permission.PACKAGE_USAGE_STATS
