Galaxy Note II software update (N7100XXDLL7) brings battery drain

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!

Some quotes from Galaxy Note II owners: 
- yes. Before update – 7,5 hours of screen work, now – 6,5 – 7 hours.
- absolutely its very noticeable
- Not really, around 5-10% worse battery, but nothing massive.
- I think battery drains fastly than 4.1.1 update. But now Exynos Xploit is solved.
- before update screen time on 8h Now : 6h30
- not battery drain but 4.1.1 was way better than latest firmwares
- yep battery now only lasts max of 24hrs , used to get 36+ , MediaScannerService seems to be the culprit

    Of course 4.1.2 update affects the battery life, no questions asked! I got 9 hours screen on on 4.1.1 at least 5-6 times, but since updating to 4.1.2 only once I got 8 hours.
    I also hate the new sick slim looking clock, the bold one in 4.1.1 was much better looking.
    Samsung should fix this with an update.

    i got 32 hours of battery. maybe battery is draining because of you guys syncing a lot of emails? facebook sync is on? i don’t know, i turn off most sync like facebook and twitter and battery is quite good, 32 hours with 3 hours of screen on.

    So should we revert back to 4.1.1 or stay with battery drain. because this is the update with exynos exploit fix or should we risk by flashing a 4.1.1 which may cause sudden death. any ideas?

    @irfan12: No you shouldn’t revert back to 4.1.1. 4.1.2 fixed the Exynos SD bug, which is much more dangerous than battery backup.
    @q.p- Around 10-15%. But if you get the update, you should do it.

    @ifran12 I’m getting 6-7 hours of screen on time, with 24 to 26 hours in total. 3G always on, auto-brightness at 50%, and lots of syncing (fb, twitter, g+, gmail, a POP3 mail account, pulse news etc.)
    With half an hour of heavy games (like nfs most wanted), screen on time goes down to 5.5 hours.
    I’m pretty satisfied with my battery life, actually.

    @hellraiser thanks, I believe I will update as soon as I get it. I don’t want to miss the “sudden death” fix. and battery life would still be more than enough for me with a 10-15% decrease ;)

    But I do have another bug, I am not sure if that’s only me or you guys are the same?

    I’m on Malaysia 4.1.2 firmware and whenever I change the “NFC toggle” icon into the notification setting toggles, after sometime, the NFC toggle icon disappeared…
    Can anyone else test this and let me know if it’s a general issue or just me?

    Thanks!

    I do highly advice anyone update his phone to 4.1.2 to do “Factory Reset” from the phone itself, and the battery life will dramatically change to a better performance.

    I did not notice any difference. Someone have mentioned here that factory reset improves battery life. I regularly factory reset my phone after flashing. Maybe that is the reason.

    I also feeling the same problem of battery drain on my note 2. One week before I updated it. How I noticed that my device battery is draining quickly then before. I give change at night. It will take 4 to 5 hrs to be fully charge in switch off mode from 15 to 100%. I used to switch on my data before update and battery goes to whole day till 11 o’clock. Now I have to change it in office. Will Samsung fix this problem?

    to get a maximum backup
    do give a full recharge cycle to ur device (when battery goes below 20% to 100% without interruption)
    use the charger provided with the device (2A) instead of ur other galaxy devices (0.7A)
    shut off ur device while charging it takes only 2-2.5 hours if u shut it off

    please give ur feedback after doing this

    My Galaxy Note 2 on tmobile has been a wonderful device since day one of purchase. Battery life was extremely excellent i would run this device for 18 hrs with 9 to 11hrs of on screen time i mean heavy heavy use. Now I have to charge my device much more often at least twice in 18hrs which makes me back off on my usage. I also notice it gets hot now when used for long periods of time definitely not good. Samsung better do something about this problem and fast. I will be hitting up their twitrer/facebook/goggle plus pages until they do.

    Does this only happen with N7100XXDLL7? I didn’t update, as 4.1.2 it’s not available yet in my country.

    I see that version named N7100XXDMA6 being released now to other countries. Does this version causes battery drain?

    I was an iPhone guy before, but switched to the Note 2 mainly because of the great battery life. Now the battery life sucks. I can’t go the whole day without recharging as opposed to going a day and a half on a single charge.

    What happened? Will there be a quick change? Don’t you realize that battery life is the number 1 factor on going with a phone?

    Very disappointed and kicking myself for upgrading to 4.1.2

    Is there anyway to go back to 4.1.1?

    Really a huge difference in battery life. Use that had before been almost 40h to 24h maximum. And to call Samsung support they just suggest we make a factory reset. Although not quite believe that I would solve, now wait a reload to see if there was improvement. In my case also notication other problems like the blue LED flashing without notice. Small “gagging” on the screen. And even a crash TouchWiz. Wait for new update.

    I received my update on 3/26/2013. I believe it was for my 3h LTE service. I was so excited that I had the LTE service in my area only to be let down. I battery my battery life for it. I did a factory reset thinking it was an app I downloaded. Nope still drained almost to 20% by 5 pm. However I am confident Samsung will fix the problem, or T-Mobile.
