Battery saving tips? - Samsung Galaxy W I8150

Hi all.....elsewhere on this forum is a thread concerning high capacity replacement batteries and whether they "really do what's printed on the tin"....so I thought I'd look at this from a different angle......
How can we extend the life of the 'stock' battery?
Does anybody have any tried and tested tips to share?.......
We all know how to do the usual....things like adjusting screen brightness and turning off wifi when it's not needed.......
It's fair to say that the majority of users on this forum will be rooted and/or have custom ROMs installed. Are there any system tweaks that unrooted phones don't allow? Are task killer apps any use at all? Is playing with the CPU speeds beneficial, or potentially more trouble than it's worth?.......
Let's see if we can make this thread a "one stop shop" for anything power saving related.......
I'll start.....though these tips will probably have only a marginal effect at best.....
1) I use Gemini app manager to view all my Installed apps to (1) see which apps are running and (2) freeze the running apps that I don't need.....less CPU usage = more power.....
2) I use LBE privacy guard to view the permissions that my apps require....if they require access to the internet via 3G or WIFI, and I see no reason for it, I'll use LBE to deny the permission.....less data sent and received = more power....
3) going back to Gemini App Manager, I look at the apps I DO need, and configure their "autorun" status. If I don't want/need them to start up at boot, I'll prevent them from doing so....they're still available to me, but they remain inactive until I need them....fewer running processes = more power......
(Lol....just realised I said "more power" 3 times.......
Jeremy Clarkson would be proud)

All-In-One T-Mobile Stock Unrooted ICS Guide

Get the most out of the T989 T-Mobile Stock ICS/Unrooted without rooting
I thought this should be a separate thread as this should serve as a good way to fix a good number of issues as well as improve your overall device function quality, as well as having all of this in one post.
(Note: I know not many of us use stock unrooted, my personal T989 stays stock unrooted, my dev T989 is currently in the Dark . This thread is intended soley for those of you that do not wish to void your warranty).
Problems After Upgrade from GB > ICS
If you have issues after upgrading from stock/unrooted GB to stock/unrooted ICS, A factory reset is confirmed to fix these issues (tested by me because I had them):
- Near zero stutter/stagger now
- Huge improvement on battery life (using the same battery saving techniques, settings, and apps).
- Mobile Life contacts no longer hangs after reboot
- Task killer now appropriately determines which apps shouldn't be in the kill all list (Apex, Nova, Juice Defender, Avast!, Lookout, Badass Battery Monitor, etc).
- Voicemail working properly now (icon wouldn't show before no matter what I did).
- Apps no longer hanging and freezing entire device for 20-30 seconds.
- Wifi Calling now working
- Facebook For Android app no longer sets itself to sync all my contacts regardless how I had the option set.
- Wifi stabilized. No disconnects in an hour and a half.
- UI artifacting no longer showing when switching between apps.
- Swype no longer stutters and freezes.
My advice with stock unrooted ICS, if you upgrade from GB and have issues, go ahead and factory reset. Worth it.
Screenshot
You can take a screenshot of your T989's screen by pressing Home softkey+power button at the same time and holding for about a second.
Keep From Being Monitored
If you scan the T989 on stock unrooted ICS, yes, it does in fact have CarrierIQ installed. However, you don't need to worry about this because you can disable it. If you don't know what CarrierIQ is, it's a company all of the major carriers went through to anonymously collect diagnostic data from our devices. They call it "data needed for device diagnostics and troubleshooting". The problem, which is pretty much why they got/are getting sued, is that it collects well... pretty much anything it can get it's hands on. I compare it to killing a quota of 3200 whales per year for "tissue samples". It's completely unnecessary. Don't trust it or the reasoning behind it.
To disable this, go to Settings > Back up and Reset. Click Collect diagnostics. Uncheck the box. Save and close. You will now no longer send, or even agree to send, T-Mobile any "diagnostic" data.
Apps OK To Disable
In ICS you can disable nearly any unnecessary application or service permanently. This will hide it from the app drawer, keep the app/service stopped, and disable it from being checked for update via Google Play. Disabling bloatware apps and unneeded apps will save you RAM, Data, a tiny bit of battery, and a lot of headache.
To disable an app simply go to Settings, go to Applications, and go to the All tab. Click the app. Click Disable. (Some items listed below may have an Uninstall Updates option instead of Disable. Simply uninstall the updates, go back into the item, and click Disable.
Here is a list of apps/services that are OK to disable (tested by me).
Note: This is just a list deemed safe. You do not need to disable every single item listed. Disabling these makes them functionless. Please do so only if you do not/do not intend to ever use them.

Battery Savings
Note: Everyone's device use is different and these items are based on my own personal testing on the T989 based on my use (which I can assure you is pretty heavy as I have kids and basically use my T989 to do all the things I don't have time to sit at a computer and do).
Also please note: With these settings and apps, you are not going to notice an instant increase in battery life, however if you use Badass Battery Monitor [Play Link] you will be able to see the improvements on the bottom right (Average Battery Life time).
1.) General good battery saving advice
Note: These are just general advice, if you use these features constantly, you don't have to disable them, and besides the screen brightness and GPS, the amount of battery life you will save by disabling most of these is very small, but this list is intended for maximum power savings, not superuse.
- Disable GPS unless you are using it
- Keep screen just bright enough for you to see clearly (Settings > Display > Screen Brightness) unless you are editing something
- Stick to either Mobile Data, or Wifi. Never leave both on at the same time. When you're using Wifi, only enable Mobile Data when you are sending an MMS (SMS's still work on Wifi only)
- Disable Wifi Calling unless you need to use it
- Disable Bluetooth unless you are using it
- Disable Motion Controls (Settings > Motion) unless you need them. (Note: The Gryoscope and Accelerometer will always remain on).
- Disable Animations - Disable both animation options (Settings > Developer options) - This will improve the speed at which you can do things, as well as improve battery life.
- Disable unneeded syncing - Settings > Accounts & Sync - Disable all items that you do not need to have sync'd 24/7, if you can change the sync interval set once every hour, two hours, or once per day depending on the item and how important it is for you)
- Disable or decrease App notification settings. Unless necessary, disable automatic update notifications on your applications individually. Keeping automatic updates enabled keeps a service for that app running in the background 24/7.
- Limit background process count. Set the maximum number of background processes to 4 or lower (Settings > Developer options > Limit background processes. This will allow only 4 or less apps to be running at once. Note that this will pretty much destroy your multitasking capabilities, but if you're a lower needs user, this can increase both battery and performance.
2.) Battery Saving Apps
The following are apps I use (all installed together) to make the most out of my battery on the T989. They have improved my battery life so much I can't begin to describe to you what I would do without them. All of these apps are free of charge, some features disabled:
- Apex Launcher [Play Link]. I am probably going to catch a lot of flack for this one. First and foremost, the default TouchWiz homescreen is a battery hungry and nearly useless piece of crap (the first part of that is fact, the latter observation is of course my opinion). There are two really good ICS-only homescreen replacements. The first is Nova Launcher, the second is Apex Launcher. Both do about the same thing, each has their own feature sets, but more or less they are pretty much equals. Why do I list Apex Launcher instead of Nova? Well this is the Battery Saving section of this post, and well, Apex uses less battery over time. Use Badass Batter Monitor if you do not believe me. And no, I don't have a grudge against Nova. I actually like both equally but again, battery saving section.
- Power Controls [Play Link] is a widget that lets you quickly change items that can eat up your battery and it is much better and more configurable than the default T989 power widget. I highly suggest using it.
- 2x Battery Saver [Play Link] will turn off 3G/4G connectivity when your phone is idle (screen off or locked while you're not using it). This does not keep you from getting calls and texts, only data is disabled, not the entire radio. This will save you boatloads of battery as well as data since we're all on caps with T-Mobile) by killing data when you are not using your device.
- GO Power Master [Play Link] is an application that optimizes your device by using a variety of different things. The first is a widget that allows you to manually kill tasks and clear services and apps you are not using. I recommend doing this pretty much every time you go to lock your device as it will save you additional battery. The second is an option you have to manually enable that, like the app above, disables connectivity when the device is idle (locked/screen off) except this app only disables Wifi. The third and best feature is that based on a profile, Go Power Master can automatically disable features at certain battery percents as your phone battery gets lower and lower. All of these profiles are customizable.
- Alternatively, you can use Juice Defender [Play Link] which disables both Mobile Data and Wifi when your device is idle, however from my experience with it on the unrooted T989 it is very unstable as to when it decides to disable things. Sometimes it does nothing, other times it does. It just doesn't seem to work well with the unrooted T989 at least for me. This is one of those apps that really does need root permissions to function properly.
Increase Performance
These are things I do to increase performance of my T989. As above, note that everyone's use is different so these may or may not help you.
- Class 6+ MicroSD card. I can not express to you how much of a difference this makes in speed of saving pictures, opening the gallery, apps that read/write data from the SD card. I currently use a Class 10 16gb MicroSD card and before it, I used a 8gb Class 4. I was able to notice the difference almost instantly.
- Keep your device and SD card clean! Norton Utilities [Play Link] can remove unused .apk files from your SDcard, And SDMaid [Play Link] can clear duplicate and temporary files from your SD card. (Note: SDMaid advanced features require purchase of the full app)
- Disable Animations - Disable both animation options (Settings > Developer options) - This will improve the speed at which you can do things, as well as improve battery life. Note that your devices Gyroscope and Accellerometer will always remain active.
- Some users tell me forcing GPU Rendering (Settings > Developer options) can improve performance, however I have read that this will break some things like the Gallery displaying pictures incorrectly. The opinion is still out on this, so enable this only if you want to try it for yourself. Note: Apps that can take advantage of GPU Rendering already use GPU Rendering, this option checked or not. This option simply forces it on every app.
- Kill tasks before gaming or high performance app use. Use Go Power Master (listed above) or the built in Task Killer to clear apps and free RAM before you launch a high-performance app (i.e. Shadowrun or N.O.V.A. 3) to increase gaming/2D/3D performance.
- Set the maximum number of background processes to 4 or lower. (Settings > Developer options > Limit background processes). This will allow only 4 or less apps to be running at once. Note that this will pretty much destroy your multitasking capabilities, but if you're a lower needs user, this can increase both battery and performance.
Best Replacement Apps for T989 (in my opinion)
Note: List includes paid apps
- Music - Poweramp [Play Link] - The reasons you should use this instead of the default music player is a list longer than I have the will to type out, but include fixing your album art, equalizer, a great ICS theme (separate download), and lyric support. Try it for 30 days for free. You won't regret it.
- Home Screen/Launcher - Apex Launcher [Play Link] - A great ICS style launcher that has a great featureset and saves battery compared to stock TouchWiz.
- SMS/MMS/FB Chat/Chat - Go SMS Pro [Play Link] - Do I need to explain this one? It's free. It's awesome. Use it.
More items/help/tutorials will be added as I get time to add them.

factory resets keeps ICS right? it doesn't revert back to GB?
I think I may do this. I'm not experiencing anything major - just some slight lag here and there.
You keep ICS yes. Minor lag will happen though but if you think it's worth giving it a try...

Nice, A thread for stock unrooted users. I also decided to do a Factory Reset and haven't had major issues aside from a few apps lagging when I turned on the Force GPU Rendering.
Minor Issues/Annoyances:
Ringtone and notification volumes can't be linked. (Anyone got any suggestions?)
Loud chirp when starting and stopping video recording.
Wallpaper scrolling missing.
Light Swype Keyboard lag here and there.
06/15 - Updated OP.
HUGE list of things you can do to make the most out of your stock/unrooted T989.
Again this thread is for those that don't want to break their warranty, not for those that are looking to actually make the absolute most out of their T989 in which case you will actually need to root/rom.

Yes, much easier this way, it also works with home/power, but much more of a pain to get it to work that way.
how does one go about doing a factory reset and/or wipe the phone completely? My phone has been buggy since day one, I think its time to wipe it clean and install from fresh.

You can do it either way. I prefer home+power but thats just because I have a really strong case and the volume rocker is hard to press.

How to increase HTC One X battery life

There is no doubt that HTC One X is the most powerful phone on the market yet, despite it's stock of amazing hardware features it also has a few lacks. And on of the biggest perhaps is the short battery life, but with a few tricks and modifications it is possible to overcome that and so increase the battery life of the best phone yet.
Well I found 6 tricks and extras that can really increase your battery life up to 20%:
1. KILL APPS USING TASK MANAGER
Notice or not but there are a lot of apps and services running in the background of your phone that suck a lot of battery and most of them are apps that you wouldn't need so killing those processes can increase your battery life.
To kill apps you have to access the task manager:
Press home icon>all apps>search for task manager and launch it.
Now you have the option of killing separate apps (press X on the process you want to end) or just ending the all by touching the stop all button.
2. Closing open Apps
A great feature in htc one x is also that you switch between open apps but it can also take a lot of battery depending on how many Apps you =have open.
How to close open Apps:
Touch the recent app button (in right to the home button)> now swipe the open Apps (the ones you want to close) to the top.
3.Disable Transition Animation
Transition Animation also take a lot of batter since the require more ram and disabling them can also increase your ram therewith your overall system performance.
How to Disable Transition Animation:
Go Settings>Display & gestures> uncheck the Animation bar
4. External Battery
Well there is always an option of getting an external portable battery which is quit inexpensive and can double your battery life.
5.System directory Modification
Just a few weeks ago a member (mike1986) posted about a file or directory displacement made by HTC that caused the short battery life. And now you can correct it and you could boost you battery life by up to 20%.
LINK TO mike1986 POST
6.Battery Save App
A battery save app could also be a life save as you can monitor exactly how much on what you're spending and then configure power save modes using apps such as Easy Battery Saver.
You can also turn off services such as 3g/WiFi/GPS to save battery consumption advanced users can also scale the CPU and more system operation with such brilliant app as JuiceDefender - battery saver.
RECOMMENDED BATTERY SAVER APPS:
*JuiceDefender - battery saver* Free
JuiceDefender Ultimate Cost Money
Easy Battery Saver Free
Conclusion:
Following those six step should improve your battery life a lot and should therewith resolve the major issue with the HTC One X.

The biggest drain is the screen, so turn down the brightness.
Those other tips are probably more a placebo, and killing tasks is a bad idea on Android. Most of the apps are just loaded into memory but not actively running so not using power, and when your phone screen is off, nothing is running (unless you have a badly behaved application that is). Even if you have most of your memory empty of applications, those memory chips are still drawing the same power regardless, so it makes sense to keep applications in memory. Why? Because when you want to use the app again, the phone doesn't have to waste CPU cycles and power loading the application from the flash memory, then loading the applications saved state, so power is saved. If you never use the app again, and memory is short, it gets unloaded.
There is also the school of thought that if you shut down all background applications and so you lose functionality (background status updates, location services, push mail services, animations, weather displays etc), you then haven't got much of a smart phone!
The system directory modification related to an old version of the firmware, I doubt anyone is effect by that issue now.

It wouldn't effect your internal system apps

I do appreciate your replay but it only shows you those task that are running separately (not internal system apps) and if you kill them it does make a difference in the overall performance. And some operations like navigation running in the background continuously uses GPS and even Data constantly, so if you end it, it does make a difference.
You are right with the screen brightness, I thought about it and came to a conclusion to just leave it at auto because no one would like a dim display.
So it wouldn't completely turn off your data or calls or corrupt your system since you wouldn't terminate any internal system apps

+1
And also control 3G/WiFi/BT radios as and when needed , there are battery saver apps like Juice defender that intelligently turn off 3G and data connections.
Advanced users can also play around with custom kernels, CPU speed settings and Kernel governors, etc.. (can help with custom ROMs)
Thanks for the tip, I added it to it.
Actually agree with PhilipL.
Killing or managing tasks in Android is a placebo - and is likely to do more harm (in terms of battery life) than good. Plenty of articles if you google saying task managers are a bad idea.
However, managing screen brightness and background services will help enormously.

[Q] Dose installing many apps drain the battery more quickly

I have heard somewhere that installing many apps can drain the battery more quickly
I just want to know wheter or not installing apps that are not running in the background drains the battery?.
Thanks.
Sent from my GT-N7100 using xda premium
Not if they are not running in the background
Some people have installed more than 300 apps (user apps)
scribbled from my note 2 (N7100)
It's no different than your computer. You can have 50000 apps installed, but only the ones running consume active (ram, battery, network) resources.
-----
I would love to help you, but help yourself first: ask a better question
http://www.catb.org/~esr/faqs/smart-questions.html
Be aware though that many do run in the background even if you haven't run them.
Sent from my GT-N7100 using XDA Premium HD app
In General Yes, but I'd say depends on the apps, if there are 200 quality apps, (however I don't know how many are there in Play Store), and you've not turned on the background data for them, then it might not drain much. But if you've even 5 crap apps installed then they'll be enough Culprit to hog the juice more than those 200 apps.
In short, DO NOT install crap apps, do not install whatever you see. Read user reviews, see ratings, then decide. I, for me, think 3 times before installing one, even if it comes from a Top Developer tag.
Yes it does take more battery. So install the apps which you are going to use.

It totally depends on applications you have installed
If you have hundreds of application and they don't autostarts or have no sync function and just occupying storage, it won't drain battery, in usual course i do have 150 user application installed but hardly it even drains recordable juice except some of it requires auto refreshing and sync
Sent from my GT-N7100 using xda premium
There are application that can disable the apps you've installed from auto starting or running in the background. Usually the biggest culprits are the free ad supported apps that tend to randomly call up even when the phone is in sleep mode. There are many ways to stop it from happening.. If you can pay for ad free app then go for it otherwise a lot of 3rd party apps will allow you to disable those features. I don't understand why someone would install 200-300apps in the first place when you only end up using less than a quarter of those. I guess its that "you never know when you're gonna need it" habits.
Sent from the Rabbit Hole
There are a number of apps which do run in the background, even when you don't manually run them first. Applications can register receivers to trigger at various events (such as boot-up complete, call ended, etc) and complete tasks in the background, or register themselves as services. You can check these with an autostart app, or I use ROM Toolbox (https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolboxpro&hl=en - there is a free version available too).
On top of that, apps can also run scheduled tasks which can wake the phone out of deep sleep in standby, which can cause additional battery drain, through either CPU or network usage.
Unlike iOS which kills most background apps after a couple of minutes, Android apps can run indefinitely in the background, unless of course they are killed by memory management first.

[Q] Don't keep activites -developer option saves battery life?

Does enable this option help save battery life? as the process is suspended once user quits it. We all know some roguewares would keep themselves active even though not running forground and draining tons of battery.
Unless you are trying to debug an app do not enable this.
It's for developers trying to develop and debug their applications behavior.
MAYBE if u have rogue app installed it may help JUST for that app. But that's a BIG maybe. And then it could cause other apps to have to relaod constantly which will DEMOLISH battery AND performance due to higher CPU usage.

I usually choose close all acitive applications upon finish using the phone, so I guess this option would do this automatically for me? I've found if I leave certain apps active my battery drains way faster.

The developer setting for kill all apps upon exit is NOT the same as clearing recents. It isn't doing the same thing.
Which apps by the way would you say are "staying active" ?
You can check to see if it is those apps specifically that are causing drain by using apps like Gsam battery monitor (my personal choice due to its user friendliness) or better battery stats app. In Gsam battery monitor you can open the app usage section to see exactly which apps used esactly how much battery/CPU wakelocks/time held awake/background CPU vs. foreground CPU/ etc....
I would say that MAYBE for a very specific type of usage that this option may help in battery life. But it without a doubt will eventual degrade performance, due to more CPU cylces needed to fully open an app from scratch vs having it cached in ram. The setting is for sure meant for developers trying to debug their applications behavior and not meant for users to get better battery or performance. If it WAS meant for those, it would have been enabled by default. It will surely mess up multitasking, which is what android is really all about. TRUE multi tasking with apps running in background. So that is what would really depend on your usage I would think.

I think this usage suit my usage very well, I use my phone briefly for calling, maybe very rarely webbrowsing, or sometimes wechat, so I want an app to stop completely once I finished using it since I probably won't open it again in 3,4 days.... I am not those smartphone addicts that's constantly playing their devices.
I only use webbrowser when I was outside and need to lookup an address... no, I don't even use facebook.

Best battery life and performance.

Hey all. Just wanted to get some input on getting the best bang for your buck when it comes to battery life. Though I've never been one for task killers and battery saver apps, recently I've been testing out a few different apps. Avast (uninstalled as I've never seen the need for anti virus on Android personally), Battery Doctor, CleanMate (I think It was called) and a few other battery saver apps. However, I cant seem to come to a conclusion on whether they help or hinder. Or if I'm even using them right.
The thing is they all seem to tell me different, conflicting info so I can't really make heads or tails out of it. They all seem to tell me different apps are running in the background and all suggest I do different things like kill apps, clear cache, free up memory, etc. What I have always used is system panel to kill a malfunctioning app if needed, cachemate, and SetCPU to underclock when the device is not in use. Now I am on a stock ROM with root and dont have a kernel that supports over/under clocking.
So I was just wondering what any of you guys to to both increase performance and save battery. Some kind of balancing act. And I don't want my experience to suffer, ex- I like my screen bright so am not going to turn it down to 30%. Stuff like that. I am kind of with the thinking that I should just use my tablet and let the system do its own thing, but then I kinda get that ocd thing going and want to have total control. So anyway, would love to hear what you guys think and use. Also, i would love love love to try out tasker but am unemployed and broke so that cant happen anytime soon. Thanks.

Out of curiosity, how long does your Note 8.0 last?
You know, I couldn't really tell you right now. I inherited it from a friend about a week ago. He thought it was bricked and junk. I just loaded up some stock firmware, rooted it and since it's new to me I have been playing around with it lots so haven't experienced "normal use" yet. I wasn't really asking because I thought the battery was bad, but I just like to have total control and wondered what everyone was doing these days. I used to be big in the android scene, as a power user not a dev or anything, but have been out of the game for awhile. So far the battery seems to be really good when it's on standby or say if I have spotify running or netflix or playing an audiobook. But it seems to drain pretty fast when im using it more actively- emailing, switching to facebook, switching to internet etc. Again, I'm not really having battery problems, and it's a new tablet to me, but I just wanna stay ahead of the game. Sorry I can't give you any numbers right now, but I'm sure you understand.

Do a search about battery.. there are a dozen threads in the Q&A thread.
I am a minimalist and don't like any so claimed Battery Booster, Battery Enhancer, or Battery Calibrator apps that are all over the google play apps site. Most of the time I leave power saver on, and have most all sync settings and apps set to automatically update and poll info and retrieve email. As I do not like to jump through hoops to get some thing to operate as expected.
Security 360 does a great job with antivirus and memory consumption with apps. You may think that you may not need an Antivirus, but this one thoroughly checks apps if you decide to turn off Google's app checking, or use private party apps from forums or developers linking them to sites.
I use Xposed framework, mainly because of the ability to turn off functions without needing to install a custom ROM. I have been there done that and am not impressed with custom ROM of any type, over stock.
Turning off DVFS, thumbnail cache, and leaving Boost Mode alone as it is defaulted off... Is my primary setting with Winam Xposed module.
I use the app Greenify, Substrate, and its experimental plugin to Xposed. It has some nice features to complement Security 360.
Since Google has corrected some issues with some of its apps, and a few other apps have updated recently. I get 2% drain with 12 hours of standby.
Also under normal use, I get 8 to 9% drain per hour, and 6% per hour browsing.
For speed improvements, I have a 633X SD card that has been tested around 93MB/S and 44MB/s write on my laptop, there are some rated double but are about less in real life performance.
I use TweaksterMod Pro from my past custom ROM experiences, only to boost read a head cache to double the default. This only helps with super fast SD cards, the slower the SD card or having congested internal RAM the boost must be greatly increased.
With online video and media, I get about 12% per hour drain doing both streaming and miracasting to tv.

update to 4.4.2 and battery calibrate resulted in 30hr+ battery life
good to read from you andr0id23 and gooberdude. I'm a little sensitive from my battery. since I bought two n5100 for me and my sister,I compare them in many aspects like performance,physical keys (volume,home,..) quality,battery life,... first I thought there's a problem with my battery.I used to test a lot of apps (some you mentioned,battery doctor,task killer,clean master,..) on my 4.1.2 stock ROM.the result was disappointing. my note hardly lasted for 8 hours with normal use (browsing,email checking,no games).it was better on my sister's tablet.
so I updated to 4.4.2 stock rom. things were like before UNTIL i did a battery calibrate.using a method almost like this link.by deleting battery stats after full charge.
I've attached the result.
notice that i have done a full wipe before update and i don't have that tones of app from 4.1.2.only the stock bloatwares and 25 harmless apps and games.this is the best result.the battery was so stubborn to live on its last 3 percent. approximately 3 hours on 1 present and the turned off.
misunderstanding some terms
gooberdude you made it nice but I just didn't get some of these thing you said.would you please explain more?

can you link me to the safe rooting note 8 OP please?why dont u use google play and triangle away.
sorry for lots of question.I googled them before asking but I gained not a good result.some leaded to good result like RootCloak.
thanks in advance.

OK, if you rooted...
I recommend getting Xposed Framework installed, then install Wanam Exposed. It has a ton of mods to adjust about anything. Though depending on model and firmware, some stuff wont work.
If you want minimal... you can get Wanam Disable DVFS... Samsung's Touchwiz has a feature to assist with games called Dynamic Voltage File System. It seems to be the root of the evil with samsung devices. Google has made it clear that battery calibration tools don't do anything to calibrate the battery. By clearing the battery stats file, all you are doing is a temporary patch. DVFS does not play well with Androids battery stats, and corrupts the data for stats, thus giving bad battery status. Once DVFS is disabled, android will properly calibrate the status of the battery. It may take a few charge cycles or manual deletion of the battery stats file and a reboot.
Again if you root, you may want to add RootCloak to allow apps from detecting root. It does it automatically once you select the troubled app. It requires Substrate and allows you to click on a link to install. Once substrate is installed it will allow rootcloak to function properly
Saferoot.zip search for it in the note 8.0 threads... I placed my copy as a file in one of the requests.
It will allow a proper root without having to flash. So no need for triangle away unless you plan on a custom ROM.
If you use saferoot, you can always upgrade to 4.4.x at a later time without having to unroot or do any trickery.
Play is messed up... never worked right on my tablet, both with stock ROM or custom ROMs
Play music does not like a large amount of media on SD storage, let alone full Mp3tags... can't handle the data or just too many files.Also music does not stop when you reboot. after some time it starts up and plays again. Gallery is messed up with image caching. So I used Wanam to disable scroll cache. I use Nokia Music Player as it is the most robust player that is small and works well on a tablet.
Freezing google music will keep battery consumption down if you have a lot of media. as I have over 4,000 files and if any one of them has an odd character in the name, the media server goes ape and cycles a lot of CPU time into trying to index. Thus sucking power like it is cheap gas.
My sig shows what a stock ROM is capable with just a few add on apps to help get things sorted out with battery power. Right now I am in a fight with Security 360... they boogered up the app with Soccer Ads in splash screens during boot and starting the app. Other wise it is an excellent app for what it does. I use it to clean out krapp that usually is not monitored by other cleaning apps, and to tweak boot blocking apps and apps that are running in background after wake up.
Greenify works fine but you may find security 360 an added app cleaner for sleep / wakeup cycles.
great user
mmm.it worthed more than a simple thanks to me.
by the way you use it in a good way.it s about 1gb of used ram on start up for me.and 970 when killed processes.
I'll try those you mentioned.seems very usefull

have a look on this topic.it for galaxy tabs but I guess it works on Note 8 too,although it is on your own risk(seems no risk,nothing gets worth than current state )
http://forum.xda-developers.com/showthread.php?t=2398663
additionally,as I'm searching on batteries a few days,i found that there are different fuel chips out there.so we must do fuel gauge calibration method that fits our chip.If you found that please describe it here.
