Samsung recently released a software update (N7100XXDLL7) to the Galaxy Note II and this update is reported to suffer from battery drain.
*Owners of the Galaxy Note II who installed the new software update reported us about the battery drain issue.
We of SamMobile have also tested the new firmware and we can confirm that the new update indeed drains the battery much faster than previous firmwares.
The new software update (N7100XXDLL7) fixes the infamous Exynos vulnerability,”Sudden Death” issue and resetcode bug but brings battery drain.
*Samsung itself did not give any comment on this issue*yet, we expect a new update based on Android 4.1.2 before the newer Android version 4.2.1 / 4.2.2 firmwares.
If you have the same problem with your Galaxy Note II please let us know in the comments!

Re: [official] [n7100xxdlk7] battery drain thread
I ended up reverting back to 4.1.1 because of wifi issues and battery drain. It seems like Samsung pulled the 4.1.2 update because OTA no longer finds it. Maybe that's an indication that they're working on it, fingers crossed.

I have battery issues. Drives me crazy. But still much better battery life than my other devices. haha.
Re: [official] [n7100xxdlk7] battery drain thread
I cannot revert back because I am one of those unlucky bastards that used to have the SDS bug.
I also encounter battery drain and honestly it's annoying. Hopefully they'll fix for it soon.

Did they really pulled off the 4.1.2 update?
Good to know. This update was really bad. I had to do a wipe data/factory reset because even the vertical scroll was laggy.
And the battery is a lot worse.
Yes its true. I have also been having the same issue. D scrolling problem along with quite a lot of battery drain. Just bought my device a week or two back. Worked flawlessly in the first few days but with the latest update has reduced the battery life quite a lot. Hope Samsung resolves it soon.

Been having the same weird battery drain issues. My battery's charging rate has gone down to 10% per hour whereas it was more than double that earlier.
Now am in a dilemma as to whether go back to 4.1.1 or wait for samsung to fix their mess

I have no Issues after a hard reset.

Previous the hard reset was a plethora of bugs also free space began to decrease with no reason until the system was close to unusable. Then I decided to do the hard reset, after that now works very stable and battery easy last all day.

Does your wifi stop responding after phone goes into sleep? Maybe we have different hardware because mine would do that.

Damn, so that's what's going on. I've been going crazy at why my standby time went from 0.8% / hour to 1.6-6% / hour after the update. The drain is certainly noticeable and I hope this gets fixed soon.
is the DLL3 better than DLL7 as mine seems rock solid battery got the WanamLite running on mine
Dunno between 4.1.1 and 4.1.2 but I found ll7 better than ll5 for battery life.
I had huge idle battery drain after OTA update to 4.1.2 - about 2-3% every hour. I was loosing almost 20% battery over night with everything turned off. I did a factory reset and it seems back to normal now. It's probably a bit worse then 4.1.1 but I'm still getting 2-3 days with moderate use. Now it's draining 2% over whole night instead of 2% every hour.
I think I found out why my phone drain is so bad. It doesn't go to sleep.
I noticed this since yesterday. I woke up did a restart.. and look! It still doesn't go to sleep!

I too had the battery drain and no deep sleep, sine I have installed the note2core kernel (version 2.4 i think) and oc'd to 1.8ghz and the phone lasts days. No real need for the oc but it is stable and I have encountered no problems.

Hi Guys,
I am on the Three network in UK. I recently updated my to JB and immediately noticed that the battery performance has deteriorated. I used to get nearly two full days with a 2 - 2.5 hours of screen time, 1 hour talktime and 1 hour music and little maps with GPS. I can merely a day now with the same usage. I would like to mention that the standby time was brilliant on the last update I received on ICS. Is anyone facing the same issue. I am thinking of of doing a full factory reset. Not sure if that will solve the problem. The battery graph shows that something keeps the phone awake
Sent from my GT-I9300 using xda app-developers app
I flashed the french version last night and I literally only got my S3 yesterday too and I can't really comment on the battery life compared to ICS but the battery life is way better than on my Xperia Play... Anyway I intend on trying out CM10 soon.
for me the other way around
ICS used to eat battery faster.
everything depende on how you setup and how you use your phone. it's not as simple as ICS > JB or JB > ICS
All the leaks I used, including the Polish Rom, had rubbish battery. H3G is working fine. Even better than ICS (or about the same).

Yep getting similar battery as that screen shot... Seems to be a lot of wake locks also I have realised even with data turned off it still drains battery as if it was on... On ics with data off I would lose like 2% over night bit with jb data off I lose 10±% battery easily over night... Hoping this is fixed soon... I though jb is suppose to be more efficient than ics?

I know how to disable Google Now, but how to disable S-Voice on a stock (unrooted) ROM other than simply "not using it"?
Like an earlier poster, I used to get huge battery life with ICS by turning data off overnight etc, however now with JB it seems to drain much quicker.
I'm only sync'ing the minimal essential things as before, pretty much exactly the same settings, so disappointed in the battery life.
I made a point of doing a full wipe both before and after the update to be sure of starting "with a clean slate".
Some people have said that battery life should improve after a few days. Why should that be? Is it busy housekeeping its flash memory or something?
Did you try Settings->Application Manager->All->S-Voice->Disable?
Works for me.
I'm the same. Ics was much battery. I have turned everything off, disabled everything unsynced everything and batteryvstill draining at 3-4% per hour, whats the point of a smart phone if you can't use it! My battery drains pretty much the same whether the screen is on or off!
I found battery life in JB to be poor IF my wifi was connected - with wifi off or just disconnected battery life seemed to be similar to ICS. I use wifi a lot though, so for the moment I've gone back to ICS... wifi range and performance seemed to be lower in JB too for what it's worth.
Im loosing 2% overnight using foxxhound

I get roughly 10-15% more juice out of JB with identical apps and settings.
My battery life is a lot worse on stock unrooted UK BTU JB aswell ... didnt even get 10 hrs out of it yesterday ... doing a full wipe and restore just now but its taking hours to put my apps back on ..
Didnt take this long to restore a iphone or is something wrong here ...My back up is only about 300mb and its been about 3-4 hours and still just at 50% complete ...
To be honest, that looks alright to me. 17 hours with network on all the time? And look at those wakes while the screen is off.

If you guys having some battery issue or drain battery. I suggest you need to change your battery. Its not a firmware anymore. Because i also experienced this i purchased new batt then no more drain issue already.
Sent from my GT-I9100 using Tapatalk 2
Mine has notiably decreased. I solved a lot of it by freezing crap loads of apps and making a lot of adjustments with the autostarts app. One notable differace that I didn't expect was a few non-system files with 'test' in the name that was appearing under "Media" in the battery usage part of settings. I still have faster drain than normal and am not convinced I'll stay with this build just yet or not; it will take some days of testing. One good thing I noticed was that with a poor signal after being off of wifi for a big chunk of today, it didn't drain any slower than when I had a good signal.
The above said, though, about my battery life, I was previously also using autostarts with a heavy set of disables and had Dorminix with some severe tweaks. I actually stayed on AOKP as a result of better control over what ran actively (back button to kill maps for example) as the decisive thing over being on 4.04 prior to this release. Even on 4.0.4 I got worse battery life than the AOKP build that had the Earth and Moon aligned for my particular handset. Glad to have the Samsung camera back for the time being. Maps seems to draw WAY less than on the AOKP builds on Samsung as well, including this update.

It seems like a coincidence for a number of people to all have more battery drain, due to a dated battery, when they all go to a new ROM. Some people have issues, some people don't. It seems to me that its more a device specific thing than a mass placebo effect resulting from an update. I could be wrong though, since I'm partially making the assertion based partially off of my own handset and battery.
Battery not Charging
i have updated to JB 4.1.2, 2 days back but i am facing a strange problem. My battery is not charging more than 67% even charging for more than 5 hours. its becoming HOT and after 67% its not charging more .. it is OK on all other Stock and Custom ROMS.
Battery Life, in my case, is considerably better than under 4.0.4, and it's not even comparable to CM9 or CM10 that always died very fast on me.
for me its even better, i got 18 hours of battery and still 38 pacent left... 40 to 50 messages, 30 min of wify etc
I still got 23 hours, the lastest ICS version last for 27 hours and 17 minutes
So it's the battery is it?
"Stable" ROM to a test release and it's the worn out battery, which was fine on the previous "stable" ROM, that's causing the piss poor battery run-down?

So far battery has been on par with the last update, which means there is still a drain. One thing I have noticed into do a few battery pulls or restarts every time you update so I did my second and it was funny, my battery life pre restart was 95 and post start up was 97. Right now it's at 96. So I'll give it a few days before I report back on battery life. But performance wise is just great. Same as before. Snappy and good.

Oh! ok.. i thought my battery was going crazy coz my note2 showed battery at 77% pre & 79% post restart . I'm on latest stock XXDMB2 (India) rom.
Another funny thing i have discovered is that if i charge the phone for a prolonged duration (i.e continue charging for about an hour after the battery is 100%) then the battery life improves significantly. It gives me as good battery backup as it was on 4.1.1. Charged it full 1 day 17 hrs back and with very light use 78% battery still remaining :victory:. With same settings and similar use it would otherwise be less than 68% remaining. Checked this twice and found the battery backup to be good if i charge it for some time beyond 100% charge. See screenshots below.

Just got this (DMB2, was on DLL4)) on Vodafone UK. Too early to have seen any differences yet though!
Hi guys,
A couple of weeks ago, Note II informed me of an upgrade. I did a bit of googling and found out it was to fix some exonys bug. Seemed pretty important so I did the upgrade post haste.
At first the battery life was atrocious (like a 50% drop). The same thing happened with my old iPhone 4 but everything reverted to normal within a week. So, I though maybe things are new and Android will fix itself up after some time.
How wrong was I ? LOL. My phone gives me just a day's worth of battery life. Earlier it was a solid two days. Which was why I justified carrying this brick of a phone. It is pretty ridiculous to see the battery drop by 30% at times in three or four hours (despite zero use).
Any suggestions to improve or remove the pathetic firmware upgrade.
1. Use the nova launcer
2. Auto brightness with the slider dragged to 1/3rd
3. 3G always on
4. The battery screen shows screen taking 70% of the battery! I have the auto off timer set to 15s the minimum.
Any suggestions guys? I am frustrated with this phone post the update. Thinking of switching back to the iPhone as atleast it gave me a day's pf juice in a much pocketable format.:crying:

Honestly you can't do anything. In American english, you can't do nothing!
Turn 3G off, when you don't need it. Keep brightness at as low as possible.
That's all. 4.1.2 drains juice faster than 4.1.1, it's the truth, doesn't really matter if someone agrees or not.
You could go back to 4.1.1 ROM you know and depend on your luck for that Exynos issue. Otherwise give up on great battery backup and stay with 4.1.2, like I'm doing. Nowadays I don't even monitor how much battery backup/screen on time I'm getting, on 4.1.1 it was the opposite story however.
Hey, so should I just resign myself to a gimped battery? What really hurts is how awesome the battery was before.

Download better battery stats to make sure there is no wake lock. I will advise despite my best efforts the battery life has plummeted when upgrading to 4.1.2. Stick to 4.1.1 for battery life. It still lasts much longer than an average handset saying that

After updating to 4.1.2 my battery runs down about 20% quicker overall I would say. 70% for your screen seems severe. Mine is always set to 50% auto and takes between 30 to 35% of the battery usage.

If you go back to 4.1.1.... Stock even....you'll have the same battery issue.
After about 2 weeks of having the 4.1.2 (the second update I received) on DBT my battery life one day just magically got better! I had been having terrible battery life (like 1 days worth) for 3 months, and now I get home every day from work with 50-70% battery. I charge it every night, regardless of the %. But it just magically got better. I'd say give it a go for a week or 2, and see if it helps. I don't know what happened with mine, but it looks like the software just "settled in" because I didn't install ANYTHING new, and in fact, I hadn't even uninstalled anything! It just got better after using it. Do a few battery pulls / restarts, too.
I went back to 4.1.2 last night and right now I'm at 50% charge, 17 hours standby time and 5 hours of screen time... I'd say my battery issue is fixed.. for now lol
I also must say that after a week or so of using 4.1.2 battery went much better overnight. I automatically turn on airplane mode during night, and on 4.1.1 I had like 1-2% drain overnight from full charge. After updrage to 4.1.2 it jumped to 10-20% !!! Now, it is down to like 4%, which is not that bad. Still have to see how it behaves during the day, I think it is not any better. Well, at least that standby drain is (much) better....

This is windows os right? Things not going fine, reinstall from scratch,!

After trying for several months Android 4.1.2 official, I decided to go back to version 4.0.4 is the cause of the battery that doubles in the case of ICS, the aesthetic advantages Jelly Bean does not cover the disadvantages in battery life.

Do I need to cheat?
And do you know the counter will reset when you unplug?

I don't want to go argue about the definition of "cheating", nor will I tell you that you are wrong about the counter resetting (though I'm almost sure you are) but you definitely DID recharge (and don't try to deny it because the proof is IN your screenshot )
Great thread

Is a fact that the battery lasts half that Jelly Bean with ICS, Samsung has not yet solved the problem...

I had battery drain problem with 4.1.2, my phone would last only some 30h. Now I flashed XWLSJ and I only had to charge after 3 days 15h (still had 7%) and this is in par with what I was getting with 4.0.3. My friend who flashed XWLSJ confirmed huge battery life improvement too.

that's fairly odd. apparently they are XWLSD and XWLSJ are the same, apart of some csc changes...

4.1.2 is not so draining battery…at least i slimmed Svoice and google map(i don't need these),turn off weather widget and lockscreen weather can use over 5 days…personnally google map has a unit that always at backstage and often wake the phone…but the weather is most draining battery!only off the lockscreen weather can enlarge your battery over 25%…widget is same…so i usually on the weather only when i want to know how the weather is…
sorry for my poor english…
loving this thread....... i carry a small nuclear power pack in my pocket (My sex life is over but it glows in the dark now ) And i get 12.2 million years battery life out of mine. (Its that old my dad had it first )
really anything in the order of 10+ hours (ish) depending on if you use your phone or look at it lovingly on your desk is more than reasonable.
Be happy xda'ers
I know this probably isn't the best place to ask this, but my other half's S2 has just been updated to stock 4.1.2 and she is getting horrendous battery drain.
The phone is fully stock (never been rooted, no custom recovery etc), is there anyway she can downgrade back to 4.0.4 without losing all of her apps & personal data?
I don't really have any experience with Samsung phones, I am a Nexus user so I do have a usable knowledge of Android & hacking.
Thanks in Advance

I have to agree with the battery difference on JB..
On average I get around 3 hours screen on time, on ICS I get around 4.5.
No shocker as it's pretty much in the beta stages.
Definitely switching to ICS, until a final 4.1.2 is released.
