    Updated my GT-N7000 from 4.0.4 to Official JB 4.1.2. Got the official N7000XXLSZ ROM (Germany) from samfirmware.com, flashed it using Odin since its still not available via KIES here in the UAE. My observations:
    PROS
    1. UI improved as compared to ICS. Smooth. Faster response
    2. Got all features of Note 2 except airview.
    CONS
    1. Although the unit gets into deep sleep, battery drain is significantly faster than ICS.
    2. The heat build up on the unit is considerably higher than that of ICS.
    3. Just playing with the UI takes significant battery drain.
    I dont know if this is just some bug with the new release or hardware incompatibility. I will test some official ROMS and see if there are considerable changes may it be good or bad. For other folks out there who tried the upgrdade, keep us posted on the developments. As of this writing, sadly i’m downgrading back to ICS 4.0.4

    You can check partial wakelocks to find the exact cause.

    I am having the same problem with my samsung galaxy note GT-N7000 since i have updated it to official version JellyBean 4.1.2. The processing of my phone has got very slow and the battery drain is at the rate of 3.7% per hour as per BBS data. There are many partial kernel problems. I’ll try sending u the file here. Please help and respond through email is possible.

    Thanks.

    If it happened just after JB update, you can try factory reset first. Of course, you need backup your data first.

    Hello everyone, been quite a long while since my last post. Finally i solved the battery drain and heating issue on my n7000. I tested several jb roms for the n7000 and now im using the the jb rom from the Philippines (GLB). I find that this rom has fewer bloatware than its european counterparts, so im happy to say that im sticking with this one. No issues here by the way, battery life is good, heating is normal (esp. when u play graphic intensive games like Real Racing 3). Just dont forget to reset your phone after flashing with Odin (as mentioned by Mod 🙂 ) and you will be ok. Happy flashing people! I would be interested to hear about your stories. Goodluck 🙂

    1). Disable unnecessary widgets.
    2. limit background process to 3 (Settings–Developer options)

    Thanks for Quick response !!

    I set it to no background process for now . Let me observe the behavior for next two days . With that I have also uninstalled unnecessary software .

    One another thing that I observed is that whenever I open the mobile data I used to get few notification for some applications randomly . It seems that some of the application are keep on checking the updated . Can we disable that ?

    You probably should leave the background process at least one. Otherwise, some apps may not work properly.

    Yes, you can disable the notification for individual apps in JB. In Application manager, tap the app, you can uncheck “show notifications” (behind force stop). Then confirm.

    Alternatively, when you get the notification, long press the notification, the “app info” should pop out, and you can then un-check the show notifications.
