Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.

I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).

Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)

Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Yeah, I am used to android taking a bit to settle in. After my note 3 updated, it seems like it took a month to get back to my "normal". I hope the tablet does too, just frustrating in the mean time
[Galaxy Note 10.1 (2014 Edition) General] Sequitor2000:
Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.
[Galaxy Note 10.1 (2014 Edition) General] graewulf1:
I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.
[Galaxy Note 10.1 (2014 Edition) General] Elim:
Then not everyone would then mention that it is not change or improved (in stand-by).

No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.
[Galaxy Note 10.1 (2014 Edition) General] BarryH_GEG:
4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.
[Galaxy Note 10.1 (2014 Edition) General] rushless:
I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.

The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.
[Galaxy Note 10.1 (2014 Edition) General] gramps50:
You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.

My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

The update did not kill my battery. Did you come from a rom?
[Galaxy Note 10.1 (2014 Edition) General] jimaginet:
Agree and disagree!

I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.

So I say kk is good or better then jellybean

I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!

I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.

If it's a bad app I can find it. It worked flawlessly before the upgrade.

Im not sure. I haven't been using it much so I can't say for certain if it did.

If you don't mind the time then I would suggest you do the same, and leave it stock for awhile and see.
[Galaxy Note 10.1 (2014 Edition) General] rushless:
With battery life issues (noticed on Shield, S4 & S5 too), the external card write restriction and emulator lag, Kitkat is an avoid for me. Happily using 4.2 and 4.3 on my four Android devices.
[Galaxy Note 10.1 (2014 Edition) General] mjrshark:
recommended to factory reset after major update, it may fix battery and some FC/bugged apps , you may give it try, it may work for you and if ya did , tell us result.still didnt get update , i own lte version and its look like it will take while :(

My note 2 and note 3 battery is better

and about external card write restriction there is mode to fix it as it was in 4.3 if ya rooted
[Galaxy Note 10.1 (2014 Edition) General] Itchiee:
Still early but the Spain version seems to have better battery life for me. Over 2 hours screen time via 20% battery watching movies, playing games and surfing the web. Not sure whats wrong with the US version... Hope they update it, but im glad we have other stock options.
[Galaxy Note 10.1 (2014 Edition) General] BarryH_GEG:
My N3's battery life improved about 20% on 4.4.
[Galaxy Note 10.1 (2014 Edition) General] godzebu:
Try factory reset.

I updated to 4.4.2 without factory reset and experienced underwhelming battery and overall performance. And after doing factory reset, my tablet is like a new device altogether!

Excellent battery life and zero lag (without turning any apps off, and leaving everything 100% stock).

Even Knox works flawlessly while changing back and forth between profiles (which showed severe lag before factory reset).

I hope it helps
[Galaxy Note 10.1 (2014 Edition) General] utvol10:
Had the same issue--did a full wipe and reflashed everything and the battery seems to be about 30% better (give or take). I'm pairing it up with JuiceDefender and all my battery woes are finally gone!

My P601 battery is much better on Kitkat.

On ICS my battery drain 2% every hour on 3G and WiFi without using (on night)

On KK battery drain 1% per hour on 3G with music player using earphone (7 hour play music).

My Note 10 2014 keep doing the same thing, it goes well to 50% battery life then quickly goes down to 5% and then reboot to come back with 26% battery life. It all started after the 4.4 update. I hate it!
[Galaxy Note 10.1 (2014 Edition) General] Sequitor2000:
I had a similar problem after the update. However, the accuracy of my battery indicator has improved over time, especially after driving it below 5 % several times and then fully charging it. In one case I kept restarting it and running it down until it stopped showing an increase after the restart. The indicator is now accurate until 30% or lower.
[Galaxy Note 10.1 (2014 Edition) General] BarryH_GEG:
I had a ton of battery issues after updating including failure to charge overnight the first two nights. That was accompanied by huge battery drain. The former fixed itself and I had to delete and re-add my Exchange accounts to fix the latter. After a week everything's stable. My battery life isn't as good as it should be but I'll wait for the ROM for my region to come out before wiping and rebuilding my N10.1-14. It's something everyone should do after an update as major as this.
[Galaxy Note 10.1 (2014 Edition) General] kessomatt:
So after multiple factory resets I still have the battery issue. Charge to 100% only to drop down to 20% within an hour or sometimes even minutes. Then back up after a reboot. Can anyone tell me the most efficient way to get this to Samsung? I tried initiating a service request on their website for the sleep of death (which fixed itself somehow) and I got a broken English response saying I might need service and to reply if I did. Well I never heard from them again after I replied.
[Galaxy Note 10.1 (2014 Edition) General] jjdevega:
I was having superb battery life prior to 4.4.2 and was enjoying the ability to play my game's like MC4 and COC while plugged into the charger as it charges my tab. Unfortunately now I am unable to do this since it no longer charges while I play my games. It had started to drain and it's very sad. I use Cool tool to keep track of the battery temp and it's gone as high as 107°F! I haven't tried a factory reset yet but seems like others that have done this have seen no improvement. I'm kinda stuck. Unsure of how to remedy this.

---------- Post added at 07:40 PM ---------- Previous post was at 07:40 PM ----------

Any improvement since the update?

Update: Figured out a way! I realized that the reason for the battery drain and over heating was due to my tablet running constantly at 1900MHz smh! So I switched on "Power Save mode." Bam! Stopped the CPU from constantly running at 1900MHz and tops it at 1400MHz instead. Thus eliminating the overheating problem and extending my battery life as it was back then:) Even while playing games. only climbs to 1400MHz. CHEERS!

EDIT: Still drains:(

EDIT2: Now its charging properly even while playing games. I'm totally confused now lol

Staying on 4.3 since no desire to root and want to keep sd writes. If 5.0 does not change this I will remain on 4.3. Happy with 4.3 so no need to rock the boat.

I finally ended up replacing the original cable for an after market 6ft cable and it actually solved my battery draining while in use issue. It also has made charge time back to normal as well around 4 to 5 hours. Finally done with this issue:D

I did have a severe drain issue on my s5 only to learn there was a program constantly accessing my microSD card and keeping my phone awake.

In that scenario I formatted both the phone and the card and its been great ever since.
[Galaxy Note 10.1 (2014 Edition) General] drag80:
I recently updated to kitkat and do not at all feel any change in battery life. I think it all depends on on which version of firmware you are using. There are so many different roms available may be some have bugs or something. I feel no adverse effects of kitkat.
[Galaxy Note 10.1 (2014 Edition) General] xdauserr:
Installing 28000mAh batt:System ignores actual voltage, when estimating charge level.

Check low and high voltages on your battery

You can do this with many software from Android play store

My high voltage (100%) is 4.315 and low was 3.6 or 3.4 (not quite sure because now I'm testing new battery)

It seems like operating system does not estimate charge level from the battery voltage

It is rather done from power consumed from the battery

High voltage is always 4.315 because of constant current / constant voltage charge algorithm

But if you start your new firmware from a low charge, operating system can underworlt and damage your battery

Hello guys,

a silly question but can I upgrade my tablet to 4.4.2 Spain STOCK version without tripping the knox? I'm on 4.3 stock -Belgian model. We have been waiting and waiting and waiting but it doesnt seem that Samsung is ever going to upgrade the rest of the N2014 p-600 tablets. Some were lucky and received the upgrade and some like the Belgium, Netherlands, UK not... :(
[Galaxy Note 10.1 (2014 Edition) General] Itchiee:
Yes, and most are multi language so that shouldn't be an issue either.

You'll trip knox messing with the bootloader doing a root or installing custom recovery.
[Galaxy Note 10.1 (2014 Edition) General] saied7:
Thanks for the response. Can you send the link or the guide of how to upgrade properly? My guess is I have to do it through Odin right?

And is the Spain version still the best at this moment or are there newer updates for p600?
[Galaxy Note 10.1 (2014 Edition) General] Geordie Affy:
KitKat has made my Battery life better and at the same time worse. I'll explain...

Before KitKat on standby it used to drop 1-2% per 12hrs, For the last 2 days it has dropped 3% per 12hrs.

Now heres the amazing bit. Before KitKat my tablet would drop 10% per hour of screen time, however with KitKat after a full charge I'm now sitting 66% battery with 4hrs of screen time.

So overall I'm pretty happy with the results so far...btw I use the tablet exactly the same every day and pre-kitkat I never got more than an hour from 10% battery loss, so it seems overall KitKat update is doing my tablet well.

I hope it stay like that.

[Galaxy Note 10.1 (2014 Edition) General] Geordie Affy:
My battery seems to have finally settled since update (no idea why it needs time), it now no longer even drops a single % in a 12hour period. The other day I unplugged it after being fully charged and it was still 100% after 16hours which is awesome.

Also the usage percentage drop has also settled and I get about an extra 1hr from a full charge than I did before KitKat. So overall happy with the update minus a few app crashes which I'm hoping a factory reset will fix.

Bought my Note 10.1 2014 about two weeks ago. Right of the box upgraded to Kitkat and like everyone else battery life drained extremely fast. However, as soon as flashed the Hyperdrive KK rom things got better. Ran with that for about a week then flashed over to the Aroma Galaxy Tab S rom and battery life has been great during usage and stand by lasts days if I don't touch it at all.

I was a bit worried at first but I'm happy and very satisfied with my purchase now.

XDA roms are much better than stock roms on tablets in my opinion.

[Galaxy Note 10.1 (2014 Edition) General] truecolors123:
Thanks for this thread and everyone's inputs, I've learned that the US firmware did shorten my P600 battery life to a maximum of 6hrs screen time, with GPS off and power saving on. After flashing the UK firmware stock, it now reaches 9hrs of screen time with heavy use (mostly youtube & web surfing). The standby drop in battery is also significant less, and it should get better when the software sets in as some users reported. Right now I'm happy with the tablet with GPS and Wifi turned on 24/7.

The best part is when I flash UK stock fw via Odin 3.09 and didn't do a factory reset later, every personal apps, data and settings are kept intact so I didn't have to set my tablet up again. Some would suggest a factory reset right after flashing stock fw to be sure, but I'm happy where I'm at now, I won't ask for more. Hope you all will find the same or better experience.

I can't speak for the 3G version P601 but you can find the firmwares from all countries here http://samsung-updates.com/device/?id=SM-P601. Hover the mouse over the region abbreviation to know which country it's from.

Also, be aware that each region may have different regulation on wireless bands. So for example after flashing the UK firmware on my US p600, I can't detect the 5ghz wifi channels from 149 and above, but those below would be fine. Just wanna point out because some people think the fw messes up their wifi.
