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).

9 hours screen on or general usage ?
Screen on and mainly reading book with infrequent web surfing.

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.

Hello, that's good way but Do you setting your kernel : governor , i/o, voltage or just using default ?
And i want to ask which Kernel do you normally use in your note ? Pegasus Or interactive or hot plug or zzmove ?

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
Related
I've heard some people say they get 3 days out of their desires and others saying they get just over a day.
This thread it would be great to collect a list of people with desires and their average battery life as well as a list of apps they have installed and widgets on display and maybe the rom they are using.
Just trying to work out
I'm going to collect data and put something up tomorrow - but I noticed last night that my battery went down really quickly when my Alarm went off (using Gentle Alarm) I also confirmed this using JuicePlotter which showed the battery sharply decrease just at the same time in which my alarm was set to go off.
I also noticed that having wifi turned on didnt seem to effect battery life that much...
Yeah my battery lasts really well leaving WI-FI on too. Not sure why others have an issue with it.
My battery will last a day tops turning on from 7.30 and off again around 12am ish
During day I will use Seemic (on manual update) and use FB on net every now and then.
May occasionally go to the Market for Updates.
I only use mobile Network when I need to so I turn off and on when required.
I will play Word Up and Solitaire for 30 -40 mins a day roughly.
Battery % will vary between 65 - 45 by 6.30 pm
Today it is down to 75% at 2.10pm - although I've not played any games today so far.
I bought an X10 and returned it because the battery wouldn't last even a day despite having all kinds of task-killing crap installed.
Then I bought a Desire and had the same problem - 6, maybe 7 hours of battery.
I found a post on some obscure blog that helped me track down the culprit: there are apps that don't let the device go to sleep completely. I had two of them. And Android (at least the HTCs) have a built-in function to see exactly what those processes are:
From the dialer: *#*#INFO#*#*, choose Battery History from the menu and then Partial Wake Usage. Nothing should have more than a tiny fraction of a bar. But on mine, Grooveshark was using 99%. I uninstalled it, tried again a few hours later and saw that Mikandi was using 99%. I uninstalled that, and now I'm getting more than 24 hours of heavy use.
Some apps just don't behave.
Why would Dialer App have such a high network usage?
It shows up as using a lot of network!

Wouldn't the dialer use the network to call people when you dial?
Thanks for the "cheat code" on the hidden menu. Very interesting.
I can sometimes squeeze 2 days out of my battery. I'll only get a day and a half on this charge though because of lots of txting and facebook use.
I found this menu option in Settings > "accounts & sync" > Background Data. I turned this off and seem to get a little more battery.
Changing the brightness down a bit helps, and i'll set the screen timeout to lower as its at 1 minute now. Plus If I use friend stream instead of the facebook widget then it updates when I want to and doesnt keep active.
Least amount of battery time i've had is a day. I never turn my phone off.
I never get a full day out of mine, maybe 8-10 hours max... I have no idea how some people claim 3 days, I'm not exactly a power user!
Stock ROM (not a provider one, just generic) on T-Mobile UK network
Wi-Fi and GPS off
Widgets: Standard Flip Clock, SMS, FriendStream, Stocks (2hr update), Agenda, News (2hr Update)
Market Programmes: K9 Mail (1Hr e-mail updating), ES File Explorer, Shazam, Voice Search, Pkt Ebay, Tricorder, UK TV Guide, GBCoid
In Standby (screen off), not using web, not calling, not texting, not using apps, I lose around 10% per hour, faster if anything at all is on.
Oddly, despite the very poor (for me anyway) standby life, in call life seems really good, I made a call last night for an hour, where phone was in the orange phase when I started and still hadn't gone red at the end...

I wanted to try turning background data off but sadly the market does not work when you have this turned off (a warning pops up when you try)

True re the dialer. Was thinking network as on net use.
anyone got background data or mobile data turned off?
if so whats your battery life like?
also anyone tried with 3G on and compared to GSM ONLY?

From the dialer: *#*#INFO#*#*, choose Battery History from the menu and then Partial Wake Usage. Nothing should have more than a tiny fraction of a bar. But on mine, Grooveshark was using 99%. I uninstalled it, tried again a few hours later and saw that Mikandi was using 99%. I uninstalled that, and now I'm getting more than 24 hours of heavy use.
Some apps just don't behave.

Well the only app that have a bigger bar is Android System... Is this normal?
Settings ; About phone ; Battery ; Battery use and it will tell you when it was last unplugged and what has been using it.
4h 27m
Cell standby - 45%
Phone idle - 45%
Wifi -7%
Android system - 5%
Display - 2%
Obviously you can see from that I've hardly used it. A few texts, checking email periodically. Display brightness is on full, weather update is set to manual. Only have a few apps installed. Main one being data counter widget.
2000kb wifi
780kb cell.
Oh, and SystemPanel, tells me I have 93%.
Switch off 3g when you don't need it,this can nearly double your standby/idle time ,use a 2g-3g toggle if its a pain.
Juice defender with its plotter can give you very useful info on when your phone is using its battery the most.
On idle with 2g 1% per hour is normal, with 3g 2-4 %.
As soon as that screen goes on start thinking 15-20% per hour!
Most smart phones are the same,my x1 ,touch pro all got caned when I first got them,but a bit of experience and a few tweaks later they were doing 3-4 days.
Also flatten it and fully charge it when switched off helps too.
My battery life is pitiful too, im a pretty light user now ive had time to play with the phone for a while but battery will always need to be put on charge by around 10pm when only unplugged around 7am the same day.
I bought up the partial wake usage list and UID followed by a number is using twice the power of Android System.
Does anyone know what the UID is?
My battery life was rubbish until i updated the radio version to 32.37.00.32U_4.06.00.16_2. I am also using MCR3.1
Before my battery life would be fully discharged within 7 hours. Now i have 1day+ Not too sure as i now have a brodit car mount that charges my phone during my commute.

To update, do you need to root your device? I don't want to root mine, but I want to get the best battery life possible.

Stating the obvious, but if you don't use your phone, your battery will last a long time!
Personally I need to use my phone (otherwise why would I have bought it) so have push email running with full Exchange sync 8 till 8, FB & Twitter syncing once an hour, spend a couple of hours a day making calls, connect to WiFi using my iPass account whenever a hotspot is available and spend a lot of time dealing with emails etc.
I put my "less than a day" battery life down to the fact that my screen is on and doing stuff for much of that time.
Of course if I just leave the phone on the desk at the side of me and don't touch it all day, even with push mail and all that sync, if the screen is not turned on much, I get 2 days.
It's the screen that eats the battery. The more it is on, the shorter the time between charges.
Wow I don't understand how you people get such amazing battery life!
I am no noob anymore regarding Android and Smartphone's in general, so I understand most 'hints & tricks' in this thread. But simply for me this does not work.
Some important stuff:
- I ALWAYS have 2G on, never 3G.
- I use wifi at home and in most places I go
- I have almost everything set to 'manual' updating
Ok.
For example my last situation:
I unplugged it at 23.30 yesterday. I used it for a little bit, over wifi. Checking twitter, surfing the web, watching some video's in HTC Flash Player. I went to bed around 02.00, watched some Law & Order that's why it was so late. So before turning off the lights, I turned wifi off. The battery was around 80-85%, from what I remember.
I wake up at 12.00. The battery was still above 50%, that's for sure. I do some facebook, twitter, news, etc. All over wifi.
And now, just before 17.00, my battery was dead (while I almost typed this entire story on my Desire -.- I was pissed). So that means, about 17 hours? Which about 10 hours I slept and the phone was doing nothing, over 2G!
So yeah... and when I read all your story's about 2 days (48 hours) I am really like: WTF
Some more details:
-No live-wallpaper. Just the black 'carbon' one.
-I used to use LauncherPro beta, but battery life was just as bad. Now I am back on HTC Sense. I have some widgets, like the Calander widget, a small music widget, bookmarks widget, etc.
-I tried to find out what uses the most battery while sleeping with that code and it showed Android System. So nothing weird there.
-Again, everything set to MANUAL updating
-ONLY 2G.
-Brightness set to auto.
So really, I think it's my wifi that sucks the battery life out of my Desire. I remember when I went on a trip and was just 'listning' to music, my battery only dropped like 10 to 15% in 3 hours.
-----------
Btw, I remember that this 'some people have great battery life some people don't' story was the same with the HTC HD2. The only different thing there was that I was one of the people with the 'good' battery life. Now I am on the 'losers' team
Any help would be great!
I see lots of posts around the Interwebs complaining about battery life on smartphones (specifically Android ones, since I don't hang out on sites that are aligned with evil Apple), so I decided to consolidate my knowledge for people with Slide's to improve their battery life.
DISPLAY
This uses about 80% of the power according to battery use on auto-brightness. On a bright day I can read the screen at about 1/5 position on the brightness bar which cuts down heavily on the battery use.
There's not much else we can do to cut down on screen power usage, so moving on.
CPU
This one requires SetCPU, I strongly urge you to buy it from the Market (it's just a few bucks IIRC) and supports the AWESOME dev. If you're cheap just go download it from that link.
Once you have it you'll want to set up profiles! So click profiles, check the box next to the Sleep profile and choose 480,000/480,000 with ondemand scaler! I have no idea if it actually changes anything but the placebo effect is nice. Next back out of that and set the CPU governor to performance. What this does is clock the CPU to 600mhz constantly instead of scaling between 480mhz and 600mhz as the additional power is needed. It cuts down on choppiness while barely increasing the amount of battery required (in my experience the Slide tends to jump up to 600mhz when I'm not doing anything anyway).
Sync
Turn auto-sync off or set the sync intervals to the highest number possible (once a day I believe). It takes power and most of the time doesn't download anything important. If you really need some data just go and hit Sync Now and, well, it syncs.
Autostarts
There is this nifty little paid application in the market (costs like $1.25 or something) that you absolutely need: Autostarts
Basically applications launch when triggers are triggered, alot of these are pointless and just take up RAM and power.
These are what I have disabled:
After Startup
{Any 3rd party apps that aren't widgets}
Calendar Storage
Download Manager
Voice Dialer (unless you, yaknow, use it)
Maps
Mail
Calendar
HTC Media Uploader
My Account (unless you like the power alerts that take up power!)
Connectivity Changed
Download Manager
My Uploads
HTC Media Uploader
Genius Button
Media Mounted
My Uploads
Application Installed
Voice Dialer (wtf?)
Pico TTS (sem-wtf?)
Application Removed
Voice Dialer
Application Replaced
Maps (lolwut?)
Autokiller
There's an app called Autokiller, it changes the internal task killer's settings as to when to tell an app to shutdown (at stock settings this is almost never).
I use the moderate preset, but you may want to increase it if you never want to have to manually kill a task. Note that this method tells apps to cleanly shut down so data is saved (such as the page you are on in the Browser)
Additional Settings
In Mobile Networks set to GSM only (no 3G)
Turn GPS and WiFi off when not in use
Turn always on data off
Use a silent or vibrate alert method instead of sound alerts
Turn off your screen whenever you can
If you flashed ENG-BUILD flash the updated RADIO!!!!!!!
Protips
Do several battery cycles every 6 weeks (Charge to 100%, discharge to 0%, charge 2 hours past green LED while phone is off)
Espresso is heavy duty stuff, use a non-sense ROM for additional speed
Charging via USB takes significantly longer than charging via AV
Live Wallpapers will use lots of battery
Use wallpapers formatted at 480x320
Limit the amount of widgets you have to around 5 (unless they are from the same app, like Beautiful Widgets) they constantly refresh and do their thing in the background
I learned most of this thanks to enatefox's guide which I modified to suit the Slide, a coffee fueled mind, and general observations. If you have anything to contribute please let me know and I'll add it!
check general, few threads there on this .. it seems the development section is the hot spot around here..
an APN widget will do wonders, or even juicedefender.
i disable APN until I need it. screen is about 30% always. after everything i do i lock the screen.
on a normal days use (1-2hr phone calls, 30-50min of browsing the net, a ton of text messaging, and streaming slingbox) I'll have about 60% battery by 10pm.
great guide. thank you.
does autostart continually kill those processes? I ask because that long list of bloatware you listed is what is irritating me on my slide and even when I force kill them all they restart themselves every 5 minutes. I have taskilller set to kill them and they come back like the herp constantly.

Autostarts does not 'kill' processes, it disables them from running when certain triggers are triggered.
For example if SpywareApplicationOVER9000 runs everytime an application is installed, and you disable it in Autostarts, then it will not run when an application is uninstalled

Can you write up a quick how to for Juicedefender?
Disclaimer: Although there is very minimal risk but I am not responsible for anything happening to your device, do it at your own responsibility.
Sorry for my bad English.
Hi guys! I am using this device since a week but its battery life was pathetic even on stock rom and Engineer Version. I decided to switch to cm as it has the best battery life for all devices and I flashed OptiBean RC2 by mac20dnangel and found out the same pathetic battery life. I mostly use 2G and wifi, a few calls and texts and battery was going flat after 5-6 hrs. I checked in Settings>Battery and found out that the most battery eater was Android OS which was about 70%. So, I searched the forums and found many helpful threads (thanks to all those devs) and did following things. Now, my phone's battery can last a whole day easily and Android OS under settings>battery has come down to 7%.
First of all I turned off Location Services as the GPS service was involved in a CPU WakeLock even GPS was turned off in Settings>Location Access.
Also, the following system apps were real battery hog. So I turned them off. For doing this, go to settings>apps and click ALL tab. Tap on the app and tap disable. I disabled following apps:
1. Android Keyboard (if you use some other keyboard. i am using smart keyboard pro)
2. Apolo or Music app (if you don't use it as i am using jet audio plus)
3. DSP Manager (which was always running in the background and was a major battery hog. Many people like it but we have to live without it)
4. CM Updater
5. Exchange Services (if you don't use them)
6. Face Unlock (if you don't use your face to unlock screen)
7. Google Search (i don't use it)
8. Google Text to Speech Engine (also was a major battery hog)
9. Pico TTS (same as above)
10. Messaging (i use go sms)
11. Picasa Uploader (if u don't use it)
12. Search Applications Provider
13. Google Talk (i don't use it. don't disable if you use it)
14. Talk Back ( was a major battery hog)
15. Voice Dialer (if you don't use)
Also, always turn off wifi, bluetooth, gps, autosync, 3G/4G, auto rotate when not in use. Live wallpapers are also major battery eaters.
After that I installed Auto Killer Memory Optimizer which is free on Play Store. Open this app and tap on the wrench icon present in upper right corner. Tap advance system tweaks.Check Apply on boot and 2 min delay before applying. Check Memory Management, Battery, Sleeper, UI and Network. Now go back and check Apply Settings on Boot, Enable Advance Mode, Enable Kill on Click. Now hit back key to return to app's main screen. Tap on change and select strict or aggressive as you like. Close app and reboot.
After that I calibrated my battery. To calibrate, charge your phone to 100%. When battery indicator reached 100%, unplug and plug again after 10 sec to be sure that its 100%. Now pull and re-insert battery. Then connect your charger to be sure that it is 100% charged. Now unplug and reboot to recovery. In advance select wipe battery stats. Then reboot device. Now you can use your device but don't plug the charger or data cable and let the battery die as you normally use the device. When battery reaches 0% and device turns itself off, power on again to make sure that battery is actually dead. Now, plug in your charger and charge the battery to 100% in one shot. Once more, let it die by itself without charging the device. After battery is fully dead charge it again to 100% in one shot. After these steps battery should be calibrated perfectly.
One more thing, go to settings>developer option, uncheck Force GPU Rendering and check Kill app back button. Now you'll able to kill any application in the foreground by long pressing back softkey. Use this to kill games and other battery hogging apps when you want them to exit.
I hope after doing all these steps you'll find an improvement in battery and I believe these tips can be used in any ROM and any device.
Edit: Don't hope for battery lasting to 2 or 3 days as the massive screen used by this device consumes a lot of battery and 1830 mAh battery is just not enough for this device. Try to buy an extended battery if you want more juice.
umm, disabling auto-run on boot with something like Gemini App Manager and lowering voltages with something like SetCPU or NS Tuner probably can help too.
I posted this in another thread but I'm not sure if it was the correct place so I moved it here.
I'm having big battery drain problems with my phone, please see screenshots for more information.
On the screenshots you can see that my battery lasted 7 hours one day and then almost 5 hours the other. I'm not sure what caused that, there was no major change in my daily routines with the phone, except maybe listened to music on my bluetooth headphones for more time than usual.
Here's my setup:
My phone is the LTE version (T999L)
I don't currently have any battery management apps (except for the battery monitor app "Wakelock Detector").
Stock 4.3
Not rooted
Screen is AUTO
Sync is ON
Wifi OFF during my work hours, I only turn it ON at home (at nights, but the battery is normally drained before that).
Bluetooth ON all the time because:
- The phone it's paired with my car
- I use BT headphones when at work
- And my Smart Watch 2 all day long
Casual gaming (I don't play much during the day, maybe for 30 minutes or less daily)
Can someone help me analyze this information to see what's wrong with my phone?

My first guess would be to clear the data from any media related apps. Go into Settings > Apps > All Apps and look for any Media apps (including Downloads, Download Manager, Media Storage, any music apps you use, etc.). Then, click on them and click "Clear data".
Then reboot.
Let me know if that clears your battery drain.

Thanks a lot for your reply Bass_Man25.
OK so I tried this, I cleared data of a bunch of apps (including music players). I basically sorted the app list by size and cleared the data of the most heavy ones (more than 5MB in data), rebooted and left it charging until today, I woke up at 6:30 AM unplugged phone and now at 12:32PM my battery is at 20%, I don't see much change.
I'm thinking there must be an app causing this drain because the bluetooth can't be causing it, but I can't figure out which one.
I've been thinking of backing up my phone settings and such with Kies, factory resetting it and testing it out unless someone else has another idea.
it seems you have weak to mid-range signal most of the day. also, assuming you're Wi-Fi is not actually on the entire time, to disable the wi-fi from always scanning in Android 4.3, you have to turn off\uncheck the option in Settings > Wi-Fi > press "Menu" > Advanced > "Always allow scanning". that will help a lot

Thanks for your reply Cobra281.
I actually don't have the WiFi ON during the day, unless my signal is pretty bad so I don't think that will change anything. And what do you mean with "it seems you have weak to mid-range signal most of the day."? Does having weak to mid-range signal drain my battery?
Have you tried Better Battery Stats? You can find a link here in XDA. Install that and let your ROM run for a while. It'll show you any kernal or partial wakelocks keeping the phone awake.

change the setting as i mentioned, because the Wi-Fi location scan is running, you have to run it via: turn off\uncheck the option in Settings > Wi-Fi > press "Menu" > Advanced > "Always allow scanning".
and yes, weak signal will cause more power use, as the phone is constantly trying to find decent service.
Check this screen shot. I have kitkat 4.4.2. Had really bad battery life so I did factory reset but no improvement. I am very new to this forum. I am charging my phone 3 times a day. I have rooted this phone.
That screenshot doesn't give any helpful information. You want to give at least 4 hours with as minimal usage as possible
For better battery
1) make sure WiFi always scanning is disabled in WiFi advanced settings
2) only have auto sync enabled to what is necessary, or disable it altogether and manually sync
3) make sure Google now is disabled in its settings
Change your launcher, seems like your launcher is eating some battery too. and also turn off unncessary google services, like location, GPS etc.

Its only a minute of battery usage so I wouldn't worry about any those apps for now until they post a longer usage screenshot. You are correct about location and GPS, can't believe I forgot those
Those little tricks did amazing job. but second and third line are still bothering me. Is there any way to bring android system usage down?
Actually Every Android Phone will have usage with Android System, and OS.. So, when you get atleast 11 hrs, thats normal usage. Average is 10 hours of battery line per charge.
