Hi everyone! My note 2 battery is driving me insane. I have been using my note 2 for like 2 months. And I had been following the recharging cycle where you only charge the battery when it reaches 5% or less and remove from socket when it reaches 100%. This method has been working real well for me. I used to get really good battery life. I would recharge it to 100 and remove from socket and keep it there. I might only start working with it after 2 hrs of idle time a nd the battery percentage would be like 98 which is pretty normal. But two days back when I had to go out I found my battery level at 24 % and since I had no other choice I had to recharge it for 10 mins. That's when the problem started. After coming back home the battery had pretty decent juice left in it and I left it idle. After an hour or two when I checked the phone it had already switched off. I was in shock and tried to switch it on but it didn't work. So I thought of charging it to 100. After almost 3 hrs it was fully charged but since I don't work on my phone so late in the night, I removed it from socket, switched it on and left it there idle. And when I woke up after 5 hrs it had only 69% juice left in my battery. I checked my running apps and there were none. I had my data connection stopped. And still only 69? Thats kinda weird right? Is it because I recharged it before getting to 5 %. Is there a way I can remove the battery cycle cache or something. Please help.
Take a screen shot of the battery usage and screen time.
That's horrible and nowhere near acceptable. Use GSam/Better battery status to see what's draining your battery. It's highly likely that it's some rogue app doing it for ya. Or else it might be faulty battery too, if that's not the case.

To find out,it is better to root ur phone. Then install better battery stats,and see whats draining your battery. You cant install bbs on unrooted phone.

I won't recommend GSam at all, just found that it drains my battery itself.
No, BBS doesn't require root for many functions, but still rooting would be even better though.

- Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Unzip the attached Odin3-vX.X.zip file
- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)
- NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.
New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!
You may now optionally want to install and run Triangle Away to reset the flash counter.

battery drain
Hi guys I have a very unusual problem. My note 2 is already rooted within a week after I brought it. I have tried different roms n never changed my modem. It’s DLK7 from the beginning. And also I have tired different kernels but still I have the same problem.
Sorry let me come to the issue.
That’s my battery drains very quick if I am not connected to internet. Wearied isn’t it. I know. If I am connected to internet by data or wifi from night to till morning I have only 3% to 5% drain (screen is off coz me n my note 2 is sleeping). If I am not connected to internet the drain is about 40% to 50, 60% some times more.
When I checked I noticed that play store or some times facebook massager is using the battery this much. Once when I was in a very busy situation my note 2 is getting hot near the rear camera and my battery is draining very fast.
I googled it but I didn’t get a proper answer.
I think when I am not connected to internet facebook massager or play store is trying to sync with the internet with out realizing that there is no internet. It is causing the cpu over use and not letting the phone to go to sleep.
Can any one help in this matter?
The only way I have found is to set a task killer kills this apps repeatedly or stop them from syncing. Both will reduce the battery drain but it will make this apps useless.
Please help…………………….
There's really no need to let it drain down to < 20% before charging. If anything, that would be causing more harm than doing shallow charge/discharge cycles.
Source:
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Use the app greenify, and apply it to Facebook. Play store shouldn't be causing this, but clear its data to be sure.
If this doesn't help, you should install better battery stats, to further diagnose any wakelocks that might be causing this.

If you don't use an app, disable it from settings---->applications. Apps like Google music tend to autostart and slow the device and reduce the juice
Hi guys
Now I am using moon rom v10 n same time I updated my modem to latest DMG1 which comes with the rom and it seems that my problem is solved. Still under testing but yesterday I switch of all my internet and I have only 3-4% drain I don’t see any problem as I said still under testing. I will come back with more results.
As i900frenchaddict said I have noticed the new map is showed in the battery usage screen and it show 21% of usage but it didn’t drain from my battery but it’s there and I checked to force close it but it’s already stopped, but again it’s there showing its using 20-35% usage from yesterday.
Don’t know what’s going on. I hope its jest showing their n not draining my battery.
I hope this will help others.
Press thank if this helped anyone.

To remove this unusual Google Map usage since last update, I realized that freezing it using Titanium Backup (and reboot) was not enough, the app kept on being displayed at a good place in my battery usage. But freezing it + non allowing Google's localization services stopped the problem.
Just I regularly use Maps, so now each time I have to re-eanble localization service, then use Titanium to unfreeze it.....

For the past 3 days my battery is dropping at an incredibly fast rate. Even if its idle it will drop about 20 % every half hour with little to no use. I rooted my phone and am now running fresh with kings kernel but no change. I an even dropping in airplane mode. What can it be? I left it at 90% connected to wifi with the sync off and when I woke up 6 hours later it was at 20%. Any solutions?
Sounds like mine, just turning on the screen drops the batter 1-2%.
Hit menu and click on settings. From there, go to About Phone and then to Battery. Note the awake time and turn the screen off for thirty seconds or so. Turn the screen back on and check the awake time again. If it's not within five to ten seconds of the time you noted before you turned the screen off, something is keeping your phone awake, which does a number on the battery.
square parts or system panel might give a better idea of what specifically is draining your battery, or preventing it from sleeping correctly.
It seems fine, about 15 seconds difference. The weird thing is this only started happening about 3 days ago, I rooted yesterday, and its still doing it.
Go for what Fachadick said. Download and install Spare Parts from the Android Market. Go to Battery History and click on the dropdown box where it says "other usage" and click on "partial wake usage". If anything is taking up one of those bars, that's your problem.
If there's nothing notable there, it could be damn near any of your applications. When you root, you lose settings for you apps (depending on how you rooted), so your autosyncs could be going crazy. Might wanna check those.

What he said Rooting won't fix battery issues. Rooting and installing a new ROM is just like reinstalling your OS. It can fix things or not depending on how it is configured. Likewise it won't fix your phone if hardware is bad.
does it drop steadily or just the first 5-10% or so? There is a well documented issue where the trickle charge stops at 100% and then shuts off so the phone actually drains a bit before it kicks in again. When you first unplug it, the reading may drop quickly until it reaches the real level.
Likewise depending on what you have installed and how it is set up, there may be something keeping your phone from sleeping. Check for partial wake use like the previous poster said and that will tell you what process/application is keeping your phone awake and draining battery.
i had this same problem about the battery before i rooted my phone. after i rooted it i got overclock widget and i get through the day with so much more battery left. i make sure my battery is full right before i go to bed, i put it on airplane mode and go to bed wake up around 7 a.m.(my battery is always at 98 when i get up in the morning so 2% in about 8 hrs) and i get home around 8:30 and my battery is at 48%. and no i dont leave it lying around with the screen off. i constantly go on, text, internet etc.
hope it works for you too!
your friend.

Mail is showing with more fill-in than any other program, when I click on it, I get the details. Can someone help?

It doesn't appear (to me anyway) that you're having any issues with partial wake time. You may have a runaway app draining your battery and cpu - system panel is invaluable for hunting those down. It will show you each running process with exacly how much cpu it's used. It gets even better and gives evenmore detail if you let it monitor your system over time.

to be honest, I'm not sure - I don't remember what kind of detail it gives you in the free version, but the app is so useful to monitor cpu and battery, as well as for hunting down rougue apps, I would recommend the paid version as a "required" app for all rooters.
when you load it up, the default screen is essentially a taskkiller - but more importantly, you can go into settings and have it show ALL processes, and if you select one of the apps or processes from that main screen, it tells you when it was started, how much cpu it used, how much memory its used, and at least in the paid version, a historical graph of cpu usage - so you can see exactly when it used the cpu over the past 2 hours, 8 hours, 1 day, 3 days, or over the past week.

Bluetooth is off, 4g is off (when's cincinnati going live already!??! Just the heart of downtown and the mall)
Wifi is off, and I've been turning off gps now, but i always used to leave it on and made it through the day.
"Cell Standby" is next with 8%, everything else below that.
I kill everything with task manager now and it doesn't seem to help at all.
It is not possible to exaggerate how fast the battery is being drained. It drops by 1-2% each 45 seconds or so. I've done the Charge-for-8-hours-turn-off-charge-trickle-charge-unplug-trickle-charge-unplug-etc thing last night and no help. This is with no widgets installed, no live wallpaper, no music, when for months i can make it through the day with a little pandora, bluetooth while driving, a game or two, internet, maps, and several other apps throughout the day. I've stopped everything but messaging and phone calls and it still drains just as fast.
PLEASE HELP!
I don't know if this applies to anyone in this thread, but after installing a new rom sometimes I forget that the Gtalk/Gchat app resets itself to automatically sign in, and drains the battery while running in the background.
Changing it to not run automatically helps out for me, although I feel that I may have gotten slightly better battery life out of the rooted stock rom than running the King kernel I'm using right now. At least in terms of percentage drop. I never really reset my battery stats or recalibrate after installing a new rom, don't know how much that has an effect on the readings.
This is turning into a deal breaker
Its not latitude, off. Not ANYTHING as it still happens with everything off and all apps killed in task manager.
No background, no live wallpaper (even though i used to have one all day). No music (even though i used to have pandora on a couple hours a day). screen brightness is always low (even though i used to leave it above medium, and would turn it up to high to watch video or a game, and still made it most of the day before).
The phone's battery use thing swears its "Android System" thats taking by far the most, not even cell standby got larger when i unplugged it in the basement where there's no service.
i've turned off everything i could think of, no apps 'auto update' and i've put all syncing and updating and stuff to manual or off that i could find.
I don't think its a faulty battery because it is ridiculously noticeable that something has changed in that ANDROID SYSTEM is now a power hog. Why and what do to?????

Have you pulled the battery lately? Give that a shot.
Hi all fellow forum members! It was about time to retire my old Galaxy S2, and i decided to buy a S4 Mini. About the same size, better specs and everything. But i dont like the battery life at all. I dont think its normal for my battery to discharge 20% over 8 hours at night. Does anyone have the same problem? I have been trying different approaches. I installed Snapdragon BatteryGuru, put the phone on power saving mode all the time, even switched 3G off, although without 3G there seems to be an improvement, but I'll let you know how's that going. So my concern is that i might have a faulty device.. or software.. idk.. when i had crazy discharge syndrome on my S2 i just changed the kernel and/or the ROM. Any advice or opinions on the battery life of the S4 mini will be welcomed and appreciated!
I don't have too many battery problems, I guess. My phone has been off the charger for around 10 hours - and the battery has dropped to 85% - which I think it OK. I've sent some text messages, checked e-mails, used WhatsApp and had a few phone calls, not exceeding 10 minutes in total. Oh, and the GPS is on 24/7 for now, but I've just got the phone rooted, so this will not be the case any longer. The phone says it still have some 7½ hours left - which wouldn't be enough for an "all nighter" tonight.
I have disables many of the push notifications, which might be the reason why I think it's a fair battery life so far. I used to have the SGS2 as well, which lasted around the same as this phone I reckon. The biggest hog is the Google Services/Framework that takaroundes up 25% of the battery usage at the moment.
I have though of having getting an extra battery for this phone, as it's always nice to have one charged.
My I9195 uses about 3% during night (7 hours, 3G data and wifi off). Try to use an app to see wakelocks used on your device, e.g. Wakelock Detector or Better Battery Stats - they might provide you with some hints to apps that keep your mini from deep sleep, which can cause the battery drain.
Sent from my GT-I9195 using Tapatalk 4 Beta
If it's an I9195, can you try to disable NFC and see if it improves?
My biggest drain is the screen. The device lasts about as long as my friend's S2 (we were playing a coop game together) and then surfed the net over 3G for a while.
We both scrambled to look for a nearby charging socket at almost the same time
Thanks for your replies guys! I will try those apps and report back. Wakelock already found one of my apps that has awaken the phone 1200 times.. shieeeeeeeet.. hopefully now that I have disabled it things will go better..
Hi all! I have found the source of my battery drain. It's Google location services. Turns out it's a common problem on android 4.2.2. I tutned off Google location an I my phone drained 2% over 8 hours. Sync, wifi and 3g were also turned on. There is a fix over at the nexus 4 forums, but it requires root and I don't know if it will work on our galaxies. If you have root, google nip wakelock fix, try it and report back.
I had battery problems on my s4. Turns out it was the SD card. Removed it and battery improved. In the end I had to change it for a new one.

Which one did you use? Sandisk 32GB?
I got an S4 mini for my gf with that card and it has terrible battery life.
The battery drained from 100% at 7 in the morning to 15% at 5 in the afternoon...
That's surely not normal...
Edit:
I noticed that the "media" service took up almost as much cpu time and power as (active for 1,5 hours) as the mobile connection.
I suspect, that some corrupt media files or whatever kept the service alive, which tried to scan the DCIM folder over and over again.
I checked the SD Card which was full of almost 5GB of old pictures pictures which for some reason couldn't be deleted because of "unknown errors".
So I took the SD Card out and put it in a card reader, to back up the files. Then I deleted the files, put the card back and formated the card.
Then I copied only some of the new pictures back into the DCIM folder... I'll see tomorrow if that helped.
Battery Drain
Hi iconata,
Can you let me know how to "disable" Google location services, which you observed as the source of battery drain? I believe I have disabled it but the battery drain issue still persists.
And FYI - the following is the message I wrote to Samsung and am waiting for their test to validate the result of my S4 Mini. Based on what Samsung told me, the Safe Mode calls out same phone settings as Factory Default, but it seems the following test cases did reveal different resutls from what Samsung told me...
Message to Samsung
-----------------------------------
Hi,
Thanks for advising to check battery under Safe Mode. The following is the 3 test cases I have done but I still have BIG battery drain issue with my S4 Mini.
All the test cases were performed under same conditions:
1. 3G on
2. Power Save Mode on
3. Standby for 8 hours overnight, from 12:00am ~ 8:00am
Test Case-1: All the extra apps installed
- Battery drain: 3% per hour (as I already reported)
Test Case-2: Safe Mode; long press volume-down key, with Safe Mode shown at lower-left corner on desktop
- Battery drain: 0.7% per hour
Test Case-3: Factory default settings; reset to Factory Default setting; all the data were deleted and no extra apps were installed; the phone was back to the original Factory default setting
- Battery drain: 2.9% per hour
Test Case-1 and Test Case-3 almost came with same battery drain issue at same drop rate, so those extra apps installed for Test Case-1 shouldn’t have contributed to this battery drain issue so significantly. However, looks like Safe Mode and Factory Default were very different, although you thought the conditions of the 2 should be same.
I still have battery drain issue even after rolling back to Factory Default Settings, and I cannot live with Safe Mode. Please help.

Hi iconata,
Can you let me know how to "disable" Google location services, which you observed as the source of battery drain? I believe I have disabled it but the battery drain issue still persists.
And FYI - the following is the message I wrote to Samsung and am waiting for their test to validate the result of my S4 Mini. Based on what Samsung told me, the Safe Mode calls out same phone settings as Factory Default, but it seems the following test cases did reveal different resutls from what Samsung told me...
Message to Samsung
-----------------------------------
Hi,
Thanks for advising to check battery under Safe Mode. The following is the 3 test cases I have done but I still have BIG battery drain issue with my S4 Mini.
All the test cases were performed under same conditions:
1. 3G on
2. Power Save Mode on
3. Standby for 8 hours overnight, from 12:00am ~ 8:00am
Test Case-1: All the extra apps installed
- Battery drain: 3% per hour (as I already reported)
Test Case-2: Safe Mode; long press volume-down key, with Safe Mode shown at lower-left corner on desktop
- Battery drain: 0.7% per hour
Test Case-3: Factory default settings; reset to Factory Default setting; all the data were deleted and no extra apps were installed; the phone was back to the original Factory default setting
- Battery drain: 2.9% per hour
Test Case-1 and Test Case-3 almost came with same battery drain issue at same drop rate, so those extra apps installed for Test Case-1 shouldn’t have contributed to this battery drain issue so significantly.

Hi pudin! You can turn off Google location services from maps app. Go to settings->google location settings and uncheck allow Google to use your location. And to further improve that you can turn gps off, and turn it on when you need to. Yesterday I decided to root my phone because greenify was asking for root permission and everybody was putting the good word for that app. Turns out it's a total croc... you can hibernate downloaded apps, but you can't do the same with pre installed. 0 use. Further more I started to receive an annoying notification that my phone's security has been compromised and it needs to reboot. Got angry, downloaded an official firmware from sammobile, preinstalled, turned google location services off and got this pretty decent battery life. Screenies are below, feel free to post your thoughts. Please note that I keep BaterryGuru and PowerSave on at all time.
Battery drain
Thanks for prompt feedback iconata! Now I can confirm the Google location services have been disabled on my S4 Mini. Also, I don't enable GPS unless I need it so those battery consumption numbers were tested without GPS running in the background. I got the call from Ssmaung tonight telling me my phone consumes more power than what they tested, so I'll return it to Samsung for further diagnostic tomorrow. Will keep you posted if any update.
BTW, I'm not that kind of guy brave enough to root my phone like you guys...
im having 3% battery drain over night
using 2 sims.
wifi off

ill repeat the test today from 100% battery and see
battery drain during standby
Hi,
Checked the image you posted and it looks like you were still doing something such as making calls and playing game over night. Your 3% power consumption per hour is similar to mine, but in my case Cell Standby and Device Idle are the 2 major items consuming the power the most over night, when the phone really enters the standby mode. Try to have your phone enter the standby mode without doing anything over night and check if the result is still the same.
strange thing... my battery was showing 16% left.. and went dead..

New FW update that improves battery drain
In coincidence I got notified of a FW update just yesterday night, one day before I sent my phone into Service, and it did improve battery drain significantly, from 3% to just 1% per hour over night after I checked the phone this morning. You guys may want to check the update as well, and I'll test my phone again tonight.

Which firmware?
I flashed the pre-rooted MG4 (over the stock MG4) yesterday, wiped the phone and froze all the samsung bloatware stuff.
That thing is still draining about 4-6% per hour while just lying around untouched. The phone is in power saving mode.
new test factory reset, all bloatware removed, just whatsapp is installed
screens
http://db.tt/nZFb2QKa
I still have 1.7% battery drain per hour I think is still bad
GMS arena seems to be the only site mentioning that issue:
Unfortunately the higher than average battery drain in stand-by mode prevented the Samsung Galaxy S4 mini from getting an impressive overall endurance rating. Even so it did more than well and if Samsung improves the stand-by time with future firmware updates, it might be one of the longest-lasting smartphones on the market.

After the 10.4.1.B.0.101 firmware update my battery has been draining extremely quickly. Today it went from 100% to 25% in 6 hours with the device in airplane mode. When I look at the battery usage in Settings it says that Google Play Services used 63% of the battery. I Googled this and I saw that there was an battery drain issue with Play Services that was fixed with ver 4.1. Well, I have ver 4.2. The other high item in battery usage is labeled Media using 27%. I did not use the phone for anything, it sat idle in airplane mode.
I'm also getting random vibrations. Sometimes when I'm holding the phone it will give a quick vibration notification. I don't know where that is coming from.
I initially did the OTA with the device rooted that resulted in some severe problems. So, I unrooted and reflashed it with SEUSS. So, that should have totally wiped the device and put a fresh image on it. I have no other problems other than this extreme battery drain.
Anybody have any clues? Anybody else seeing this?

Install better battery stats and look at what's consuming your battery?
I used my phone pretty heavily today and still have 11% left... I plugged it in about 2 hours ago long enough to grab some pictures off of it...
I'm unsure why Google services went nuts... oh and I had my screen on full brightness for an hour or more while working on a project outdoors in bright sunlight...

Download tegra overclock from google play link https://play.google.com/store/apps/details?id=com.tegraoverclock&hl=en
you must be rooted, then underclock to the minimum frequency of your cell in tegra overclock, then minimize your cells screens brightness, it will increase yours ncell battery backup much much higher than before ! hit like if i had helped you, as i am new in xda and want to become senior member !
Huh this is not a battery drain issue.
Wipe the batterystats.bin and charge again to 100% without disconnecting the phone. Use it and voilà. (You can use Battery Calibration from NéMa in the Play store)
This will calibrate your battery. I suggest you do it after ant ROM flash or OTA update.
Root required to wipe stats.
Wow, I thought I had this problem licked but it resurfaced again today. Since my first complaint I factory reset the phone and reinstalled everything again. I have been running fine for days since then. But, then today.... same problems. With the phone in airplane mode most of the time I get the following:
I think I figured out the problem. I have a 64GB Micro SD that I had pretty full with music. I've used it without problems for at least 6 months in my Xperia before the update. After the update I noticed an extreme battery drain and it reported that "Media" was using an unusually high amount of resources. So, I removed the card and now I get phenomenal battery life using Stamina. If I don't actively use the device it will only drain less than 1%/hour. Not bad under heavy use also.
I've been out of town since all this started and I haven't had a chance to reformat my MicroSD. I am hoping that if I reformat and slowly add back in some media that it might not reoccur.
I disabled Google crap (plus, maps, play services, magazines, books, movie studio, sync adapters for contacts, calendar, Chrome browser etc). Both me and my wife get approx 5 hrs of screen time (1day + from 100% to 15%) with moderate usage, (WiFi always on, 3g/WCDMA preferred, no sync). It's Google services that run in the background, cause wakelocks and drain battery.

I did the same .. .101 killed my battery, downgraded to .569 and now things are well again. Strange.
My battery life is pretty amazing with 101
5h50m with screen on, 6% left.
When get discharged, the time was 6h05m, i tryed to print, but the cell power off lol
sorry my bad english.
.
Was skeptical about the N5100 battery life since it only have 4600mAH battery.
Now that I have bought it, it seems my worries are confirmed.
I'm running stock rom, only rooted it without other modification.
Installed and have greenify running. Not using any sim card, only using it on WiFi.
Playing a video using MX Player, drained up about 20% of battery for a 45min video. That's rather heavy imo.
Normal browsing and reading forums eats up about 4% per 6min of use.
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old.
Btw the above test were with Power Saving mode(CPU and Screen) and screen brightness was at 25%~30%. Currently on 4.2.2.
And does using the S Pen eats up significantly more battery?
Thanks in advance for the feedback.

Do a search on battery and charging by me, in the Q&A threads. I won't repeat myself here, but I go into how to correct drain issues. Many developers will push their apps for calibration. The real trick is discovering what is doing the drain. I have seen for myself how one app can do a lot of damage with media. Normally I get 12% per hour on battery usage while Miracasting Netflix to my tv, and about 10% on normal usage with WIFI always on. I have MXplayer and a bunch of apps as well running so I am not going to get the same power savings as with a cleaned up stock ROM without any apps, what would the point of having a tablet if that is the case???? I guess peeps like to show off when it comes to numbers. I like to show off when it comes to usability and function without all the apps get in the way.
my battery stats
I'm running CivZ-FLEX-BEAM-REV3.6.2 ROM.
Installed and have greenify running. Not using any sim card, only using it on WiFi, even off the WiFi before I off the screen.
Even use underclock to 1.2Ghz cuz only used for normal browsing, nothing intense that require more power.
Here's my battery stats:
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old, now 9 or 10 months already.
Now considering should I replace the battery or just get a powerbank to help.

From what the graphs show... it looks like the battery could be going bad, as there has some that say Samsung is aware of bad batteries in some units. You could contact them, but you will need to un-root if sending to Samsung for repair.
Since you are rooted, I suggest installing xposed framework and install Wanam DVFS Disabler for Xposed. It is a standalone utility from the complete Wanam xposed app. Once installed make sure both xposed is functional, and the app in xposed is enabled. These apps act as a separate process from the OS. So installing them requires user interaction for activation and updating, along with a reboot most of the time.
Once they are running... it is best to turn off the tablet for 1 minute and then plug in the USB charger and wait til it is showing 100%. Then turn on the tablet. You can unplug the USB power cable and wait 1 minute, then plug it in. Take note if the charge takes less than a minute to get to 100%. If it takes a minute or more... you will need a stop watch, as it should take about 15 to 20 seconds to go to fully charged, unless you have music or media running at the time. If it does charge quick, you can then disconnect and do another days worth of use and check your stats. Hopefully disabling DVFS will cure your issue if it is not battery related.
As for unrooting, make sure you do a clean uninstall, and have any apps that require root uninstalled. If running triangle away uninstall that as well. You may have to check within the apps settings to make sure you uninstall properly, as to uninstall from play store or the system may not properly remove the app.
Updated Battery Stats
this is my updated battery stats, now I'm suspecting it maybe due to calibration problem?
My screen on time is now 2 hrs 45 mins, and for the last 45 mins it has been running on that last 1% of battery(but with screen dimmed, as brightness is automatically dimmed and can't be adjusted when below 5%).
Even until now the device haven't auto shut down due to run out of battery yet even though been running 45mins SOT for that 1%.
Calibration problem? I've tried calibrating using calibration apps, which I charged to 100% then press calibrate, but didn't help.

Sudden drop of more than 3% at any level after doing the DVFS disable and properly charging can be one of two things.
A bad battery, or bad charging cable. Yep, I have had two bad Samsung cables, one did exactly what is happening with you, and the other did a melt down at the USB connection on my tablet. If you have a good cable from a Blackberry or a Sony/Ericson device, you can try that. I have moved over to Sony Xperia cables, as they are pretty well built and longer.
If another cable does not solve your issues, I suggest unrooting and cleaning up rooted apps before having Samsung service your tablet. It very well could be a bad battery.
thanks for the reply, I think I'll just resort to sending it back to Samsung to fix it.
Now I have made a nandroid backup already, then I flashed stock firmware, so my device is now unrooted and on stock firmware, however my flashcount is still there, and now I can't run triangle away cuz my device is unrooted already.
If I were to root it, it'll flash custom recovery again then it won't be on stock firmware anymore.

Your unroot sequence was done out of order.
Set USB debug
Root stock rom with saferoot.zip
Install triangle away
perform clear of counters
Verify after clearing in about device that custom is not set.
If so make sure triangle away is set to clear and perform clearing.
Remove triangle away
Remove SuperSU through the settings, clear for reinstall.
To make sure everything is proper... do a factory reset.
Once those steps are done, your tablet should be stock and able to perform OTA or Kies updates, without any issues with counter and root.
I just got the 4.4.2 KitKat update and now my battery life sucks!
My tablet was at 99% when I went to be last night and DID NOT USE it at all today, except when I tried to turn it on to read before bed time, the tablet shut off on its own because the battery went down to 1%!
Does anyone else have really poort battery life on their Samsung Galaxy Note 10.1 2014 Edition after getting the 4.4.2 KitKat update?
Is there anything we can do about this?
I loved my tablet before I accepted this stupid update! Grrrrr!
Better take a look at battery status on settings
Can U take a screenshot at morning to see what's happening and share with us?

FYI, I just got this tablet yesterday and it comes with KitKat. Spend sometime turning off some bloatware from the Application Manager. No root yet for Wifi without KNOX tripping, so I can't disable any other apps. Played around with the tablet a little bit and the battery life is not good.
Stats:
- Wifi Always ON even during sleep
- GPS is ON
- BT off
- Samsung crap-features OFF (Smart Stay, Smart Scroll, etc.)
12 hours 42 minutes total time since charged

But mine comes with 4.4.2 out of the box. It was not upgraded.
I have very bad battery life since I updated to kk. Talked to Samsung and they told me it was the battery. Send it to repairs and 2 weeks later I got it. It still got the same horrible battery life. Just 3h and 40 min of use.
If you wanna give this a try.....
[back-story]
When I received the US version of KK it too trashed my battery life and i don't know why but it does not benefit my tablet....
[/back-story]
The Spain, and now Mexico versions of the KK software work much better.
http://forum.xda-developers.com/showthread.php?t=2719750
It's easily updatable via Odin, all languages are included, you do not need to be rooted, and it will not trip the Knox software counter.
Plenty of instructions around here if you stumble.... Good luck.

That means I have to reconfigure my tablet again.
Stupid Samsung! Just when I thought they got their **** straight.
Yeah you may have to put a little effort into this lol. Actually you can install right on top of it and you probably won't lose much but I would recommend a hard reset anyway to start fresh....

I hard reset my tablet (remember, it's brand new), which already have 4.4.2. Configured Google account, disabled bloatware, turned off GPS, turned ON Wifi and installed Zinio for a test.
Left the tablet overnight, use it very slightly. Check out the battery drain caused by Android OS... It's definitely some sort of bloatware or 4.4.2...
I am having the same issues, was going to start a thread but will wait post here then to have some collected place to talk about possible solutions... IF AN IPAD HAD A STYLUS..... I like to be able to play around with all sorts of things but I wish there were two streams of android a stable working one and an experimental one.... sometimes it seems that even though its version 4.4 its still beta!
Note the 4.30 hour long screen time to deplete my battery from 100% to 15%... yes i know the stylus takes some toll but THAT is not acceptable.
Style of usage:
- used Papyrus for note taking
- had calculator open in floating window
- had screen brightness to 20%
- GPS off, Google Now off, little bit of music playing for about 2hours (headphones)
I noticed that my battery stats are not resetting!
I plug in the charger for a little bit and then unplug it but battery stats didn't reset?
This is so frustrating. I thought after giving the new rom some time to "settle" battery life still sucks!

Give this a try, some may not be applicable to you. I'm on 4.4 and right now I have 1day21hr and 4 1/2hrs on screen time and still have 35% battery left.

Give this a try, some may not be applicable to you. I'm on 4.4 and right now I have 1day21hr and 4 1/2hrs on screen time and still have 35% battery left.

I believe problems are less in standby time but more in screen on time. Standby barely uses any power (in my experience, except once where exchange service sucked it dry within a night) but screen on time causes much of the battery to be exhausted. your values however aren't very satifying as well if you say you had 4,5h of screen time (idk what you did then, playing games might be more energy exhausting) it shouldn't be that low. However its still better than my 4,5h and 8h total to go down to 18-10%

I don't think so. See my Screenshot. I left my device on its own and Android OS is keeping the device awake. And NO, it's not caused by installed apps,
I believe that's related to the new stock kernel.. are you on a stock rom? You can try a linaro's based kernel and post results...

Yep, stock. I actually have not rooted the tablet and using it out of the box. I reset this thing so many times and same issue.

I flashed Xluco and will give an update once I can tell if it helped or not. on stock it drained about 20% per hour no good for a tab with no hard use on it...

And 4 of Samsung "bloatware" are right there, including that stupid AllShare Cast!!
Hmm....., I turned off these 2 and now I don't get too much "Android OS" awake now:
- Picasa Uploader
- Sapamonitor
In 9 hours, I have 4 hours of screen on time but only only 1.5 hours of Android OS.
