[Q] Galaxy Note 2 Battery Drain - Galaxy Note II Q&A, Help & Troubleshooting

Recently my Galaxy Note 2 has started giving me battery trouble. Till about 10 days ago it used to give me approximately 18-20 hrs battery life on moderate use. Now for some reason i get only 8-9 hrs max without any usage. It just shows a high usage of media and the phone never goes to sleep mode. After reading a few threads i tried the following:
> I removed the external sd card and wiped it.
Result: The phone was back to normal without the external sd card. As soon as i put it back. It kept rescanning for no reason. Even though there was nothing on it. I know for a fact that the sd card isnt spoilt or even non compatible, as it was working fine for so many months. It works fine on my other phones too.
I'm attaching the log file of Better battery stats app as i was told it would be useful in answering my query. Could someone please solve this problem for me. Thanks in advance.

Media scan bug is pretty common on jelly bean. Unfortunately the only fix I have been using is using mediascan root from play store. If you are rooted then download media scan root.
Only side effect is that if you have a new media file.. You need to re enable it. But all it takes is just a click and a reboot.
Check it out and I'm sure itll fix the media scan bug.

You have a corrupted file in your sd card probably.

It might be a corrupt MP3 on the card. Happened to me, even though the music played OK. I ran MP3 validator (Windows app) and it fixed it.

Note II 16GB, stock ROM, not rooted.
I had exactly the same problem - overnight my battery life dropped from 2 days to less than 12 hrs. Mounting the SD card on my pc a msg popped up that the card was corrupt, I ran the scan and fix, put the card back in the phone and it's working perfectly again. I was very surprised but not unhappy.
This is the second card, the first (Kingston 32GB) was killed after just 8 months, 4 months later the replacement card was corrupted. All the other Kingston cards I've bought for myself and my family work perfectly, some are many years old. Could it be a Samsung problem? After using SD cards in Windows phones for the last 10 years and finding them very reliable, having one card irreparably damaged and another corrupted on the same phone in 12 months makes me wonder if it's more than a coincidence.

I've been having the media server drain for about 3 weeks now. I've used mp3 checker and removed any bad mp3s I've also tried Drketans media scanner disabler and still have the drain. It's about 10% if my battery per day and about 2 1/2 hours phone awake. Anyone any ideas?

[Q] sd card battery drain

SDcard show up under battery, surprising since there is no sd card in a galaxy nexus..
Anybody know what's going wrong or how to stop the battery drain ??
I've had this exact same issue! It happened at the same time as my other issue of app sizes continuing to climb upwards and the phone getting laggier in this thread:
http://forum.xda-developers.com/showthread.php?t=1715363
I just resorted to a factory reset, which resolved the problem. Sorry I can't be of much help, as I still have no idea what the issue is, but it was definitely taking a noticeable toll on my battery life.

I would be concerned of what you have installed on your device, that it is calling itself sdcard.
Nexus internal sdcard is mostly named just sdcard, but this is first time i see it in battery stats. Maybe it's some bad app? Maybe you should uninstall apps one by one and see if it's go away.

Nexus does not have an internal sdcard and symlinks cannot use battery so I would say its an app.

I mean that 16gb internal storage which is called sdcard in most apps. And i know that it can't be in battery stats, that's why i said it's an app.
Same problem, a solution without having to do a factory reset?
Anyone come up with a solution here?
So I'm guessing the lack of responses in this thread (and this one http://forum.xda-developers.com/showthread.php?t=1792361&highlight=sdcard+battery) means no one has any idea why SDcard usage would be so high?
Maybe it is not the amount of power that sd card uses, it is amount of power that the phone uses to read the sd card. If you did lots of things that needs reading from sd card, battery show that kind of information. Some program with wrong commands may couse this

Thats what I figured but there shouldnt be anything thats accessing it, especially overnight in sleep mode, the SDcard has more CPU usage time than any other app, by a landslide.
Have you looked at your running apps? (Settings>Apps>Running)
Maybe you can find out what app may be running called "sdcard".
Sounds a bit fishy. While there is no physically removable SD card, the phones internal memory is partitioned so you have some space which is recognized as the 'sdcard'.
In any case I've never seen anything like that in my battery drain, and even if there was, it definitely shouldn't be draining those amounts while the phone is idle..

I've gone through them but can't seem to figure out whats going on...i've also run logcat but that hasnt turned up any useful info either.
And when you press on sdcard under the battery usage, what screen shows up? Does it say it's an app? Could you provide a screen shot?

Here are screenshots from my battery usage, after clicking on the app, and my build info. I've got the same thing and its completely eating my battery life. This was within 1 hour of use.
This just started happening to my galaxy nexus -- no idea why?
GSAM Battery Monitor shows System (sdcard) running at 17% and its really affecting battery life, I can actually watch the number drain by the minute.
I am not looking to do a factory reset again and I am running Bugless Beast 4.1.1 rom and have been for about 2 months now and never had this problem, anyone have any idea what could cause this?
Just started happening to me today. I just installed lookout so I hope that is the problem. Just uninstalled it to see if that was the culprit.
I'm 100% certain Google Music is causing mine.
Mine always says sdcard and media are the processes running that are eating my battery.
I can reboot and fix the issue, temporarily, but as soon as I play Google Music it starts back. I'm going to clear data and cache (for Google Music only). Now that I think about it this has been happening since Google Music's last update ~1 month ago.
I'm running the latest Trinity kernel and RasBeanJelly, but this happened while on Bugless Beast as well, so it's not a kernel/ROM issue either.

Maybe media scanning process.
if your is rooted , download this
http://play.google.com/store/apps/details?id=com.addz.mediascannerroot&feature=search_result
you can disable the media scanner in this app, see if this media process usage decrease or even disappear.
IF your phone doesn't have root
download this version

Battery died sounds reset to default?

So last night my battery was depleted to 0%. When I charged it and turned back on all my sounds, ring tones and notification sounds reset to default. Is this because I keep my tones on the external sd?

Maybe.
Could be when battery got low enough, it turned off SD card as a way to save energy. That would have defaulted to local ringtones.
Or maybe something just got corrupted.
Our phones can get sometimes VERY flaky when battery is under 5% (in my experience).
Who really knows though. The important question is... does it work now?
Yep seems to be fine now. I agree it probably stopped the sd reader when battery died. Just checking to see if anyone else experienced this.

[Q] HELP!! Battery Probelm Note 2

There was an update that came out around 2 months ago which messed my battery up for my note 2.
Then another update came out about a week later to fix the problems in the first update.
Now Google+ even when uninstalled is eating 42% of my battery and it only lasts around 8/9 hours.
Ive killed all the apps, WIFI, Bluetooth, GPS everything is off but only managers to stay on for around 8/9 hours.
The battery itself is fine the phone is not that old.
Should i root?
has anyone else had this problem and how did you resolve it?
A common reason to root is to better manage the apps on your phone. Yes definetely root using drketan's thread. Next steps would be to install Greenify app that hibernates anything you the user has not explicitly clicked. Then install Wakelock detector (or do it 1st) to see what is still misbehaving and deal to it.
Basically, root allows you multiple measures to control your phone. But realise you're best served by reading as much information as time permits. XDA is so full of stuff, the difficulty is commiting time to dig i up and digest it! Good luck.

I was facing same problem as yours, g+ was killing my battery, surprised when I solved my problem, ext sd card was the problem, u can try to remove sd card for one day & observe before going for root.

[Q] Memory card getting formatted or corrupted every week

Hi guys,
I have been using almost all custom roms for redmi 1s. It's quite frustrating that for every week the memory card is getting corrupted or formatted and I see a message that "memory card is not inserted". I try to remove the battery and remove SD card and put it back then the memory shows it's empty. Even it happens for internal storage when I connect to my windows PC. It happened thrice. Soon after I stopped connecting to PC. Please help me in fixing this issue.
Thanks in advance.

Have you checked the memory card on a computer? It sounds like a faulty or fake card!

Thank you for your reply @david_inuk .
Yes, it was working fine in PC. Yesterday it stopped working completely. I'm buying strontium nitro 32 GB suggest me any good memory cards (32 GB + promising speed + promising warranty) .
Small query, is there any chances that due to over heat memory card fails or gets flashed because for me almost in every custom rom mobile is getting heated upto 75 degC
While charging.
And the same was happening with internal storage as well. Where do I'm going wrong?
mobile never gets heated upto 75 while charging on any rom, maybe you are using it while charging so never use mobile when its charging, and about card i think its a card problem try any other card, and tell what happens.
Yes, i was been testing with 8 GB memory card its working fine. The problem was in MC thank you so much @nishant12819...
Yes my mobile CPU is getting heated upto 72+ degree C..... Even if it is not on charging. Almost with all custom rom. Im using atleast 50apps and battery backup is also not good 4 or less hours of screen time(with greenify and ds battery saver).. Suggest me if any tips... with wakelock detector im blocking some of the wakelocks but eventhough its same. On GPS and Google maps while travelling around 50Kms it lasted 3hours
