[Galaxy Note II Q&A, Help & Troubleshooting] CitizenLee:
Hasn't ran for enough time to say really, but Media Scanner service suggests that the OS is constantly scanning the phone for new media. Do you have a lot of photos, mp3s, map data etc on it? If so move them off your SD for a while and see if that is the problem. I remember reading somewhere that this process can run continuously if there is a corrupt media file.

These threads may also shed some light on it for you:

However, I also notice your using Light Manager. Do you have this on Alternating mode as I believe that can prevent the phone from going into deep sleep.

I have some friends who have the note 2 (fully stock unrooted) so it seems I'm going back to the stock rom ill definitely root it but I'll miss a lot of the customization like more multi windows apps.. Etc but if that fixes my problems.. With the horrible Battery life I'm all up for it what kernel is a good combination with stock rom I might flash one.
[Galaxy Note II Q&A, Help & Troubleshooting] CitizenLee:
Going back to stock wont solve it if it's an issue with one of your apps (which I'm 99% certain it is).

Since getting my Note 2 a while back, I've tried all the main ROMs available, with all the kernels available... and I've never had that issue. It's not something I see any other custom ROM users complaining about either, so again that points to an app being to blame.

Check those threads I linked to... lots of good info that might help you.

Stock kernel is fine with stock ROMs... but as soon as you re-install all your apps don't be surprised to see you battery drain problem re-appear.

Happy to be proved wrong though!

Good luck :good:

You might be right but I'm sure it was the media thing was causing all the issues I wiped all data and installed omega and without downloading any app media was using 64% on first boot.. I'll have a rom backup if flashing the stock rom won't help then I don't know what would and then I might as well just go back to a custom ROM..

Well guys it seems I'm not going stock haha I finally found the fix...

What about a good kernel/Rom for a good battery life ? Wanam vs Omega?
[Galaxy Note II Q&A, Help & Troubleshooting] CitizenLee:
I've been using Omega ROMs for a few weeks now, swapping between RedPill, Perseus, Note2Core and NEAK kernels as and when new versions are released. All of which seem to provide great battery life so I think you should be fine with any of them to be honest. Check the info on each kernel in their respective threads to see if they have any particular features that you want / need (exFat support etc) and then just test them out. I haven't tried Wanam ROM in ages, and didn't use it long enough to judge battery life, but I expect it will be good too.

My first suggestion would be latest Omega ROM and latest RedPill kernel and then see how it goes from there ;)
[Galaxy Note II Q&A, Help & Troubleshooting] therockk:
#1. Im glad to hear your problem has been solved!

#2. You should most DEFINITELY install RedPill Ultimate Kernel and undervolt and use that screen off profile i suggested.

#3. Since you have been flashing ROM's left and right, i would try to format your SD card and then see if the problem persists! And there is no issue with WanamLite ROM, its the SD card.

---------- Post added at 12:12 PM ---------- Previous post was at 12:09 PM ----------

Ya, i was on WanamLite V2.0 last week And it has awesome battery life / performance. This week i wanted to try something new so i flashed on Omega V7.2 + RedPill Ultimate. Works awesome as you said! In reference to the kernels, i have tried all those kernels and found that RedPill was the best IMO and in my experience. With uNEAK Kernel i kept having an issue where my CPU would run at 1.6 Ghz 99% of the time. And i had constant lagging with it as well.
[Galaxy Note II Q&A, Help & Troubleshooting] Austin3161337:
I flashed Omega now and the camera SD card bug is gone.. but regarding the undervolt do i undervolt each point like (1.2 , 1.3 . 1,4 , 1.5 ghz , etc) by -50 mv?
[Galaxy Note II Q&A, Help & Troubleshooting] therockk:
Good, yes. For each clock speed minus it by 50. And than click the top right middle floppy button to save the settings (They get saved to the SD Card main drive). And than press the top right left (1st button) (The box with the checkmark) to apply the voltages. Done. You can go lower than -50 mV, but i would start with just -50 mV for now, and than slowly work your way higher.

Guys how much does media take up from your battery in % mine right now is 15... I have to open that up every time I reboot and whenever I'm downloading something it won't go to deep sleep even when I enabled the app.. i do have a warranty on my phone but I already rooted it and flashed roms etc.. Maybe because I have a lot of stuff in my sd card not really.. Really pissing me off I never had this trouble in any android phone..

[Galaxy Note II Q&A, Help & Troubleshooting] CitizenLee:
You can return the phone to a warranty acceptable state if need be, so don't worry about that.

My concern is, lets say they did give you a new one, that when you reinstall your apps and pop your SD card back in it, the same problem will appear.

With the mediascanner app, I think that's just like plugging a hole in a dam with your thumb... you need to get to the bottom of what's is casuing it in the first place. Let's try...

Did you format your SD and move data back?

How much media do you have stored on your SD Card?

Do use use any navigation apps or other apps that store large amounts of cached data? Reason I ask this is looking at those threads I linked to earlier, it appears some people were having issues with off-line map data tiles and the folders they create. These folders contain images that should not be scanned due to the .nomedia file contained within, yet sometimes it seems it doesn't work.

---------- Post added at 09:06 PM ---------- Previous post was at 09:01 PM ----------

Sounds like it might be something to do with the motion sensors being on when the screen is off, like for quick glance etc?

What kernel you on?
[Galaxy Note II Q&A, Help & Troubleshooting] Austin3161337:
Well man I did format and moved the data back

My Media shows up as using 2% under battery menu in Settings.
[Galaxy Note II Q&A, Help & Troubleshooting] CitizenLee:
Ok, now we're getting somewhere! That file sounds like it is definitely the culprit.

Pull the cable and plug it back in, then on your PC browse to the SD and right click, select properties, then see if you can uncheck Read Only.

Failing that, do you have a card reader on your PC, or any other decive that takes MicroSD (old phone, camera, usb adapter etc)?

If so see if you can move your important files off the SD that way. Then format on your PC, pop it back in the phone and format it in settings>storage too.

Another option would be to move your importatant data (exclusing songs if you have these on your PC anyway) to phones internal storage, then format the SD in PC and phone.

I'd still check for bad mp3s too, as with ~20GB there's a chance one or two might be corrupt ;)

Is still there after a reboot?

Mine is generally pretty low too.

[Galaxy Note II Q&A, Help & Troubleshooting] philby123:
Do you mean the stock kernel is better than redpill in the stock rom? Or do you mean that the stock kernel is better than any kernel on any rom ?
[Galaxy Note II Q&A, Help & Troubleshooting] interfreak:
The stock kernel is better on battery than redpill on the stock ROM.

On Wanamlite's ROM, the stock kernel is better on battery than redpill. I can't really speak for other custom ROMS.

I've flashed redpill, uneak and perseus on Wanamlite. From my own experience in terms of battery performance - uneak>stock>perseus>redpill.

My suggestion is to always run the stock kernel, and install Pimp My Rom from Google Play:

https://play.google.com/store/apps/details?id=com.androguide.pimp.my.rom

It's one of the best apps I have ever installed and allows you to customise any ROM to your liking with numerous tweaks. :)

[Galaxy Note II Q&A, Help & Troubleshooting] CitizenLee:
This is very true + not all users are equal in how they set-up and use their phone.

I generally flash custom kernels for the extra tweaks and features, rather than battery life specifically, as I don't notice much difference between them. I'm latest Perseus now and it's great so far, but so was RedPill and so was Note2Core and so was NEAK. Like I said on page 5, they're all good :)

Lots of people are happy with stock too though. That's why it's so cool that it's easy to flash and test different kernels so we can all see what works best for ourselves.

QFT.

I see all these tweaks to the phone, like, setting brightness to the lowest, turning on Power Saving, and limiting CPU 200-400mhz via SetCPU, and other things, like, switch to 2G, and turn off all the motion features. etc. etc. etc.

And all that does is each give you an extra few % on your battery.

Like OP says, relax, and enjoy the phone. Use it like it's meant to be used. Power is gonna be drained. Do what you like with it, and just enjoy the awesomeness of the Note 2.
[Galaxy Note II Q&A, Help & Troubleshooting] therockk:
Actually all that does is not just add a few % to the battery. All that does is add maybe 3-4 Hours screen on time, and 10+ standby Hours to the battery. All those things that i have suggested, they do make a huge difference. But every Android phone is different. When i do all those things, i get the results i just said. Maybe if you do them you will get better or worse. And all the things i do have not limited me from enjoying the phone at all! :p:good:. I used to be all about the battery. But as of late, i dont really pay attention to the battery anymore. If it goes down ill just plug it in.

But i must say i am very impressed with the Note 2. With all said and done, since i have owned the phone (About 2 months now) Even on stock rom or any rom + kernel, there has never been a time where i have had to plug in my phone to change during the day. The battery has always at minimum lasted me an entire day. :good: Hats off to Samsung!

To be honest with you I think there's a defect in your phone. Because on several different ROM's with several different kernels you're having the same problem. So I would try to maybe first:

A) Replace the battery. And if the problem still persists . Than:

B) Return the phone and get a replacement.

Further troubleshooting it in my opinion is a waste of time and will result in no success. Basically in the last 4 pages we have tried everything. I am on the same ROM is you: Omega v8.0. With RedPill Kernel Rev 10.0. And my battery life has even further increased. So there's nothing wrong with the ROM or kernel.
