pretty crappy battery life at the moment... but as OriginsOfLewis said, its a test version so i wouldnt expect too much... i have been using JuiceDefender Pro to keep the phone alive for at least most of the day... but without that it would survive half for maybe less than half a day...
my battery drains so faaaaaaaaaaaast :/
i will hope that fix it when release the final version
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.

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?

superaosp from [email protected] stock kernel or redstars depends but cm7 and stock OTA gave me better battery than 2.2/2.1
I'm running stock 2.3.3 and battery life is by far the best over various android versions.
2.3.3 has some weird bug where every once in a while the system gets into a weird drain state like it doesnt go into deep sleep correctly. i just got hit with this last night. it does happen all the time, most of the time on 2.3.3 battery life is excellent. i will lose 6% over 8 hours. but when that awake bug DOES kick in, battery drops like yours did.
you just have to reboot and check it again, the bug likely will clear itself and you wont see it again, for a while.

My N1 on 2.3.3 goes completely dead after 12hrs. I found the solution when doing a Google search. It's to go to Wifi Settings, Advanced, Wi-Fi sleep policy, and change it to Never. You'd think that would reduce battery life, but for some reason now my phone's battery life is very significantly improved. Now it's only down to about 30% after 19hrs when I put it on the charger.
It appears that 2.3.4 will address battery issues in Gingerbread.

I dont think its Gingerbread, ive used both stock and CM7 on my N1 and i was having good bat life on N1 stock gingerbread about 5-6 hours with heavy use, and with CM7 official rom i get 7-8 hours heavy use and up to 19 hours on days i barely use the phone, and on standby i can confirm 8 hours (while im asleep) it drains 6% by the time i wake up of course i do have it personalized and settings applied for bat savings.
I haven't encountered this bug with CM 7.0.3 (based on 2.3.3) but I found it very useful to let the phone just drain the battery completely once in a while (once in a few weeks) and than fully charge it.
After doing that, I can go through two days with regular usage of the device
I'm on CM 7.0.3, 2.3.3 and I'm only getting 13-15 hrs if I'm lucky. Wifi and bluetooth are off only syncing gmail and google contacts. I barely even touch my phone at work for 8 hrs and the battery life sucks.
Another weird thing is that once it gets to 15% left it just automatically dies and shuts down...very frustrating, I'm on the latest pershoot kernel too, the phone was given to me for free last month and it was originally purchased in Feb '10 so I just figure the battery is old and worn out.

No. Your battery is not aged, it just needs re-calibration.
One simple way is to re-calibrate your battery is to charge it when the phone is off or charge using a desktop charher, and you have to over-charge a bit - just leave the battery connecting to power source for an additional 1 hour or more, when the charging process has been completed.
This works every time for me.
Keep in mind that from time to time the battery may need to be re-calibrated again for peak performance.

Please post your battery life experience in here. I am doing this because if Samsung does come here from time to time, let us show them how many users experience poor battery life with the JB rom. Also, let us ignore wipes or full resets since people may receive this update via OTA or Kies and they should not have to do a full wipe or reset to get a good battery life.
No doubt it is better.

I've tried litterally every JB leak so far inckuding the official ones.
I got sick of having bad battery life on all of them, no matter if I wiped etc.
So two weeks ago I put the very first stock rom on my phone (dated may!), and let it run auto updates from my carrier.
It ended up on LH3 and the battery life is night and day better. I'm getting over 24 hours easy now with what I consider to be decent use -phone calls, lots of facebook, whatsapp, browsing and at least 90 mins of mp3 playback each day. I leave wifi, 3g and BT one the whole time and it always gets over 24 hours.
Today though I flashed the newest UK Hutchison 3G official JB as it's my carrier. I'm going to see how this goes but I'm not expecting it to keep up with ICS. I'll be very happy if it does though.
It was terrible on JB for me (less than 24 hours of moderate use).
I disabled google now and installed juice defender and I get at least 2 days and maybe 3 if lighter use.
Swedish ROM is by far the best in battery life.

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

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).

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.

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.

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!

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.

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.
Any word on when samsung would release a good update?

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

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:

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....

I get about 4.5 hours on average, and was getting about 5.5 before the update.

I hear that a factory reset helps in some cases.

I decided to dirty flash 4.1.2 and it worked great for me. We'll see how it goes after a week or so of use though
A thanks is always appreciated if I helped you.
Edit: After 50% battery drain in 8 hours of light/moderate use on wifi I'm going back to 4.1.1... I see no benefit of using 4.1.2.... The reason I bought my note 2 was to have a battery that will last me all day and this isn't cutting it.
Thank you MobileOdin for making this easy!!!
This is windows os right? Things not going fine, reinstall from scratch,!
