I have AT&T LTE version on rooted 4.1.2 with Greenify and I'm about the same, 5 hours of screen time with data off. It's not great battery life, but not sure that I can do much to improve it.
so do you think thats normal battery life but some say to get 8 hours surfing web on wifi

My device is new and I've tried breaking in the battery. Rooted it and froze any potential battery killing apps. Use it on low screen brightness. Getting 5-6 hours screen time. I have to believe that its normal, but I can't say 100% for sure.
I believe the Note 8 with LTE tends to drain battery faster because of radio feature. I have a Verizon Galaxy 7.7 that also drains battery faster than the non-LTE version.
My Galaxy Note 8 (non-LTE) gives about 9 hours with wifi on and 40% brightness. However the tablet is non-rooted (if that matters).

Yes, data over a cell network uses more power than over WiFi.

There is no such thing as "breaking in the battery" for this type of battery. Li ion batteries do not need to be conditioned like the old NiCad type batteries.
All I would recommend on a new device, is to calibrate the battery meter on the phone itself: charge to full, leave it on the charger to ensure any top-off charge is achieved (maybe 30 min or more after "full" is indicated). Than drain to 10 or 20%. This sets the "high" and "low" flags for the battery meter, so the meter is more accurate. But it doesn't change your actual battery life (just like fiddling with a car's gas gauge doesn't mean there is magically more gas in the tank).
After calibrating the meter, the best thing for battery life on a Li ion battery, is frequent short charges, as opposed to full discharge cycles.
Same Issue
Same problem here. I have 9 month old Note 8.0 wifi only. Battery life has always been atrocious. Drains 1% every 1-2 minutes of basic use By basic use, I mean internet browsing, 20% screen brightness, no other apps open, all major tasks killed. This is absolutely pathetic for a $400 tablet. If I play any sort of game, such as Candy Crush, we're talking 1% every minute. I've never gotten through an entire movie.
I finally got so fed up that I sent it in to Samsung for service. I haven't gotten it back yet, but I received an email back saying the repair was a "software upgrade." I find that hard to believe. I will post again with the results after I get the device back. My satisfaction with the Note 8 is a 1 out of 10. I wish I would have gotten an Ipad mini or Google Nexus.
I find it unusual that some of you guys have abysmal battery life. On my Note 8 I get amazing battery life, with average to heavy usage I don't have to charge it for a couple days.
I also only got it a couple weeks ago; maybe Samsung changed something inside the Note 8 since the release earlier this year?
I have a Note 8.0 WIFI that was made as an early release US model.
Like any Phone... Apps, GPS, WIFI, SD card, and Screen brightness all are factors in power drain.
I try to stay away from apps that have ads built in. Even small tickler or banner ads can cause battery drain and privacy issues.
Even though you may not see the GPS indicator being active, apps will poll GPS time to time.
In testing some apps, I found that most banking apps are too taxing on my device. Believe it or not Paypal, and Chase are real buggers to your privacy and consume more than what their apps are worth.
Bone stock with no SD card, the device consumed a lot of battery power between the first few power cycles.
I figured there must be a lot of services running in background to optimize and finish configuration of the OS.
Once that settled charging and running on battery smoothed out.
I am able to get 10% drain per hour on normal operation. WIFI always enabled, SD card installed, and lots n lots of apps installed as well.
Just surfing with power saving enabled, LEDs on, Eye watch activated, SD card installed, GPS enabled, and brightness on auto at +3, I can get about 5% battery drain every 40 to 45 minutes.
As for videos using internal speakers, I get 10% drain every 25 minutes... As the display brightness increases and speakers are at 3 with full Viper optimization.
To me being the slimmest and lightest 8 inch device, it gets pretty good battery time. One thing to note, if you feel the left side getting warm... it means you consuming power and to expect the battery to be consumed much faster.

Hi,
I have N5100 too bought from indiatimes.
Here is what I did to get better battery life out of my note 8.0
1) Go to Settings -> Developer options - > use 2 background processes
2) Do not put Auto brightness, Set the brightness to 20% it will be still be good enough
3) backup and reset - > uncheck everything
4) Google account - > put sync on first in the notification bar and then go to your google accounts and uncheck everything, then disable the "auto sync" from the notification bar
5) Sound - haptic feedback off , vibration , move everything to minimum ..
6) GPS - off , use only when required
7) Developers options - > unknown sources (check only when you need , otherwise uncheck it ) , verify apps - uncheck it
8) Open Google maps, go to settings , uncheck the location services
9) go to youtube app - go to settings - uncheck anything that has syncing options
10) Screen time out 30 seconds
11) Since you said you mentioned that you are using Greenify . I am assuming you are rooted. So you can greenify almost all apps except the launcher and the ones which you use frequently.
12) you can use Rom tool box pro or root cleaner to freeze ( maps , google contact sync, bookmark sync, yahoo finance, hangouts (if you dont use ) , kies , talkback, chrome, google play music , google + , alarm , drm , samsung account , samsung push , samsung print , weather widget, sns, fw upgrade , yahoo news
13) use system control pro app where you can set the governor to pegausq min 200 Mhz, and max 1600 Mhz
14) Go to settings - more settings - Mobile networks - use GSM mode , dont use both WCDMA/GSM
15) Go to google play - > settings - > uncheck auto update apps and also notifications ,,
16) Go to all the google apps and check for any settings that use frequent checking.
17) Use UC browser it is really good for browsing and many options.
18) When charging the Note 8.0 charge it from 0 to 100 in one stretch and dont connect to charger unless it drops below 3%. If it is getting switched off by itself no problem.
19) Go to settings - > Date and Time - > Uncheck everything
20) Go to Settings - > S pen - > Check the option - > Disabling pen detection when pen is attached can extend battery life.
Clear everything in memory in RAM before you leave the note idle.
Before you can do all this. It is better you install the right firmware.
For me XCMH2 gave good battery life. Now X note build. Below is the link to that thread.
http://forum.xda-developers.com/showthread.php?t=2345299
Wipe data , wipe cache , wipe dalvic cache , do it two times in that order.
then you flash the X note build and go through all those steps.
If you do it right I am sure you will not have many wakelocks and you will get better screen on time than 5 hours.
when I did all this the highest I got was 9 hours 26 minutes (7 days).. few months. On an average I was getting 8 and half hours..screen on time with 6 days battery life .. Max standy I got was 15 days battery life with 7 and half screen on .time ..
Your note has to sleep when you are not using. then you can get good standby time and also good screen on time.
) Note 8.0 is really an awesome device. Enjoy!

Woah! That is way too many things to adjust... Get greenify app, and startup manager app... and be done with it. I get 8% an hour and 12% an hour with miracast movies to my tv. Having sync on... to go and do sync settings manually is a time consumer... just turn off sync at the quick buttons. Make sure blue tooth and Sat are off. Brightness is manual setup to be be bright enough to give good detail and whites on movies. I leave it alone so it is never an issue on adjusting for most lighting conditions.
I added a simple tool to give wifi data speeds... so I can see how often high rates of data are downloaded. Most of the time small packets of data are always being sent for network discovery and authorization, along with apps like email and what not.

Gosh, I have been posting bits here and there, and nobody cares until now. HA!
OK, I will do a simple rundown.
OEM or stock firmware only.
Saferoot
Xposed framework
Wanam Xposed
Startup Manager for Xposed
Greenify Plus for Xposed.
Geenify
Security 360 Antivirus (Very robust app for its size, like having 5 apps in one)
Trickster Mod Pro
RootCloak and Substrate (Non-Xposed version)
Now that I have the main components listed, what to do.
Turn off in Application Manager... Will require swiping all the way to All.
Google Play Music - If updated you will need to uninstall before turning off.
Google Contacts Sync
Briefing
Clock (digital)
Favorite Apps
Flipboard
World Clock
Yahoo! Finance
Yahoo! News
In Greenify, tap on menu. I have added an Xposed module to make all apps have a three dot or line menu, so you may not see the menu without it, as I have no clue to what any app looks like without the xposed module running. There should be an option to create a shortcut. It will place an automated greenify all launcher. It will greenify any app that can be put to sleep. In settings you can do experimental options to greenify.
Both greenify and security 360 have a sleep or end function, they work together at eliminating apps from running in background and memory starvation.
If you find an app that is always running after boot up that you may not be able to manage in either app, Startup Manager in Xposed may offer a startup disable for the app, though not all apps are covered in the list. It is fairly simple just tap on the app and once it is highlighted it will not start during startup.
Security 360 will allow further actions, though it has an easier interface than greenify. You can add both user apps and system apps to the ignore list or remove them as well.
I would be very careful on removing system apps from the default list.
With all that set I keep everything setup automated... email, wifi, and syncing.
Though I keep my google account setup to not do much but sync calender for syncing Samsung calender simultaneously.
Once you kill all the google automation in your online google account... you may remove Google +, as I never liked it and don't use it, the options on your tablet will be in effect, so make sure what settings you have on your tablet are what you want before making online changes.
I left Samsung account active so I can get automated updates. With everything else pretty much running nicely without any glitches.
I have my powersaver setup with everything enabled, and no automatic dimming. Pretty much like the previous poster I commented on. 20% is more than enough for my viewing conditions.
With my settings the way they are, I use the tablet without thinking of turning this or that on unless I am using miracast or file sharing.
PS... I have GPS on for apps that require it. Even though it is enabled, it is off until I start an app that needs GPS location info. It seems only 4 apps that I use pull from GPS. Google Maps, HD widgets,YP, and a Navi app. I have disabled internet location settings, as they are unimportant. Knowing which apps will pull location info during use makes it easier to control location than expecting games and browsers tell me what they are doing.

Glad to know your battery life improved and you can try for even better screen on time and also in terms of days. I have put up some screen shots for your reference in the attachment. Please check.
I forgot few tips there
Converting Google play services,
Google Bookmark Sync,
Google Contact Sync,
Google Calendar sync
Google Chrome
to user app (they are system apps)
but not to worry, you can convert them to user apps.
what you can do is
1) Uninstall Google play services and Google chrome that came installed with the firmware
2) Install Google play services and Google chrome from aptoide.apk app , convert it to user app (in case if it is showing in system app)
How to convert Google play services to to user app?
If you have ROM toolbox pro latest version 5.9.5 or 6.0.3 you can open app manager in that , then just do a single click you will have bunch of options, swipe your screen to right then you will see more options where you can see below there will be option , convert to user app
3) Xposed frame work (latest version)
4) download and install call recording mod (if you need, its worth)
5) download and install greenify and check the option in xposed frame work (activate it)
6) Install Android firewall
once you convert all of those system apps to user apps, freeze them.
Google play services - dont freeze. freeze the rest ..
Max battery life achieved on my Note in terms of days was 15 days but i lost the screenshot , my second highest was 11days and odd..
Note:- I don't use power saving, flight mode , no battery doctor , no wake lock detector.. I use ONLY greenify with Xposed framework and I freeze the battery sapping apps.
Before turning off the screen, I make sure I have closed all apps from recent apps and then clear some ram from task manager just to ensure there are no wakelocks.
So far it worked out wonders and my battery life is excellent and very happy with my Note 8.0 after 11 months of usage.
Battery drain is 1% or may be 2% in 10 hours standby .. and that helps in prolonging battery longevity over 4 days , 7 days , 10days or even 15 days.. If you have battery drain overnight then your Note will come for 1 or 2 days but by curbing the battery drain over night you can get it running for 4 to 7 days easily with excellent screen on time.
I am currently on firmware X-Note 5.1 4.2.2 and use my Note for watching Videos, Songs, games, reading Flipboard, Google play stand, S-Note, PDF reader , editor ,
I got screen on time of 11hrs 12min in 4days 20h..., previous highest screen on time was 11hr 6m, and before that 9hrs 26min (stock firmware)
XDA developers is great forum, after going through lot of posts by developers these are the tips that worked wonders. converting system apps to user app was something I found out from other developers in XDA , i was hesitant at first but when I did it eventually I was extremely satisfied and you can see the results.
I hope you can get ever better results..
the fastest my note 8 drainning only in 30 minutes screen on
Drainning very fast ... with 100% brightness and disable power saving mode

Bad battery life
Hi all,
I'm running several apps that should run all the time (AdGuard, Network Speed Meter) or for a long time (speed trap warner,...) but OxygenOS kills them after a certain period. Some of them restart automatically, some don't. Of course all of these apps are 'not battery optimized'. Is there any chance to prevent OxygenOS from killing them?
Are there custom ROMs that can overcome this problen?
I'm on the latest OxygenOS Pie Beta, but the behavior was similar on Android O...
Thanks a lot,
W
Did you try locking the app via recents menu?
Thank for the info, didn't know that.
Unfortunately it doesn't help, Adguard and the network monitor don't appear in recents. The speed trap warner automatically starts and stops when I'm in the car, i don't want to open recents manually every time.

This is not changing anything,e ven with disable battery disabled, even with adaptative battery disabled.
I have the same problem. I have not found any solution whatsoever. This is really frustrating. I've made sure apps aren't optimized. Advanced optimization is disabled. Developer options background limit is at standard. I've pinned the apps in recent apps and it still happens. Apps get killed all the time.
For example,
1. I use Google Fit to start tracking a run. Within 10 minutes of tracking, the app is closed and workout not tracked. Its not even like i touched the phone and opened other apps during this.
2. I have VoIP account setup in the default dialer. Calls come through only 50% of the time cause the dialer is closed.
3. YouTube Music, constantly gets closed if i simply pause the music. Within 2 minutes, the app is closed.
4. Trying to transfer 15GB of files through Explorer app from phone to file server, never succeeds if i don't watch the app and keep the screen on.
5. Plex gets closed and therefore my photos don't auto backup with the phone is plugged in.
This is absolutely ridiculous! Why the hell a phone with 8GB of RAM is killing apps is beyond me!
Custom ROM on the same phone, like Lineage OS, no issues. Can have optimization on, battery manager on and all. In fact, battery life is better on custom when its not killing the apps! Seems to be the only solution until OOS can stop killing apps so aggressively.

Hi all,
I seem to get this issue with pretty much every single Android Device I've owned in the last 8 years, particularly Samsung ones, and that's the good old "Android System" battery drain.
I have tried everything over the years, except rooting the device, but nothing has ever worked as a permanent fix.
I have tried:
- resetting device
- clearing cache
- restarting phone
- Shutting down background tasks
- Low battery usage location settings
- Deleting apps
- a million other things
But one way or another, Android System will eventually make its way back to the top of my battery usage stats.
I've come to the conclusion that it's the OS itself that's badly coded which causes this.
Has anyone, anyone, ever figured out a way to get on top of Android System battery drain?

I'm not sure this effects that, but while setting up phone from a factory reset etc, do you Uncheck the fields that pop up such as analytics, wifi scanning (even while off) and all the other ones ?
I uncheck all the crap i can. It's possible if you leave those checked that could be the culprit a bunch of services running in bckgrd....
Just a guess....but if you say this has happened on all your androids....maybe this is why.

Yep I un-ckeck all of those fields. Makes zero difference overall (I have tried both ways).

That sucks, could it be due to social media apps syncing constantly? Sorry I'm out of ideas....

Ibreak, maybe the problem is caused by apps sending reports and analytics via google services, samsung related stuff always sends analytics, even if you do not facebook, the damned thing is always lurking and consuming resources, google app and chrome also are resources-hoarders, I use ccswe to disable all useless firebase, crash, analytics, ad listeners, campaign trackers, components and some boot listeners within many apps

Hi all,
I seem to get this issue with pretty much every single Android Device I've owned in the last 8 years, particularly Samsung ones, and that's the good old "Android System" battery drain.
I have tried everything over the years, except rooting the device, but nothing has ever worked as a permanent fix.
I have tried:
- resetting device
- clearing cache
- restarting phone
- Shutting down background tasks
- Low battery usage location settings
- Deleting apps
- a million other things
But one way or another, Android System will eventually make its way back to the top of my battery usage stats.
I've come to the conclusion that it's the OS itself that's badly coded which causes this.
Has anyone, anyone, ever figured out a way to get on top of Android System battery drain?

Enable Developer option
then go Settings» Developer options» running services
Here you should see a bunch of services running. A number of them should fall under Android System, close all related to Android System (it is ok to do so)
Then under Google Play services close all (well two of those services are persistent so they will auto start back in a couple seconds, lockscreeen service and Google location service), nothing you can do about this other than to disable Google play services which would then cause a lot of apps to cry like pandora, samsung internet browser, play store, YouTube etc.
Then go settings» apps» 3 dots at upper-right hand corner» show system apps» android system» battery» disable background activity
On each restart Android system background activity will be automatically enabled so just disable it on each restart.
The thing is it could be a number of apps or services that is causing the issue through Android system but a good indicator of which app might be causing your issue is to check Android system memory which is right below background activity, there it should show which app is accessing the memory through it the most. Disable that app or clean its cache/data.

Thanks lennie,
How do I check this?

It's in the same place you'd find background activity, but instead of going to battery, go to memory.
settings» apps» 3 dots at upper-right hand corner» show system apps» android system» memory
At the top above average memory usage you should see the app.
I would recommend using a package disabler (ccswe from the play store or package disabler pro from their website)
You can disable a lot of things but DO NOT disable
boot agent (could lock your phone in bootloop)
Android system (could hand your phone on boot up)
One UI (unless you have a different launcher installed and enabled)
IMS is important too
There's one more I can't remember right now, but you get the idea.
If you're not too sure if something can get disabled with no harsh side effects then just post the question
settings» apps» 3 dots at upper-right hand corner» show system apps» android system» mobile data
Shows a list of all the apps that have access to the network through Android system, disable the the ones you're sure you're not using or will use. That should shorten the list of potential battery drainer.
Thanks again.
It just shows an app called "face" under Android System memory. I assume that's for face unlock.
Be careful with disabling OneUI, because it will also disable the task manager and you'll got a really ugly one instead.

Yeah that's for face unlock. I used to use it but since the fingerprint scanner update it has been working really well with my screen protector so I don't really need it anymore so I have it disabled.
If you don't use face.
How i use my phone to maximize my battery is simple. Things I don't use or need I keep them disabled, some I simply disable until I need them like the play store or galaxy store etc. Every other day or so I would check those apps to see if there is an update I might want to install.

I only use the fingerprint sensor, but it's still shows (only) Face there. Any idea?
There's really no fix to Android System drain, it's especially worse when you're on mobile data.
Is there a way to prevent an app from ever being killed? I have 2 examples:
1) Fitbit app (background sync service, specifically) - when this stops running, some features on my watch quit working until I launch the app and sync manually.
2) Battery monitor app - I've tried AccuBattery (my preferred app), GSam, and BBS, but they all get killed and restart, and therefore give inaccurate information. BBS doesn't die as often as the others, but I don't like it as well. All 3 have persistent notifications, so I can tell when they last restarted.
I've set Battery Optimization to "Don't Optimize" for all of these. I've tried turning off all 3 of the settings under Advanced Optimization (probably unnecessary, no noticeable difference). I've also Locked each of these from recent apps. Are there any other settings I'm missing that could prevent an app from being killed? Possibly something new to Android 11? Fitbit and AccuBattery worked fine on my previous OP7P with Android 10.

I have try to to go to developer mode and go to standby application. go inside and set the app you want to always on to active and remember still set battery to don't Optimize and locked the app. Do not click the clear all button.

Interesting, I haven't seen that before. Thanks for introducing me to something new. All of the apps in question are currently grayed out and say Exempted, so they shouldn't ever be put into standby.
Disable all power management*, Android does fine without it. Address any remaining power hogs individually on a case by case basis.
Power management will cause erratic behavior and can even increase battery usage even after its lame "adjustment" period.
To check if it is fully disabled go to Developer options>Standby apps, all buckets should show to be in their active state (and can't be manually assigned), if not power management is enabled.
Make sure allow background usage isn't disabled on the apps you want to run.
*yeah turn all those optimizing toggles OFF.
Only fast charging should be toggled on if you use it.

How does one disable all power management? I don't see any sort of global switch for that. Turning it off entirely seems drastic, but I agree that power management is generally more trouble than it's worth.
I did verify that the apps in question are allowed to run in the background and use unlimited data.

It seems like you're setting up right. Check the Stand by apps status.
When you first load Accubattery it gives an option to disable task killing in settings, Pro version.
Uninstalling then reinstalling it sometimes works for me; clearing its data does not. I was getting the same error message until I just reinstalled it
Just don't take Accubattery too seriously... it's useful up to a point.
I'm on Pie. Google really screwed up 10 and especially 11... so yeah it could something new as Google insists on changing things even if they're already nearly perfect
If that fails check with Accubattery for guidance with 11. They are responsive to emails.
They may also be punching out an update.
