Hi everyone,
I just updated to JB and noticed that Media server (66% usage) has been keeping my phone awake for the entire time (4 hours). Is there any fix to this? It's running hot and draining 10% per hour (and it's been idle).
Disable it? uninstall [root]?

It's always recommended you so a factory reset after any update. That should fix it.
The thing is though, I wiped everything, installed the update using ODIN, wiped that and then flashed the Black Jellybean rom. :/
Look at whsts under media server in batt stats.
Go in app manager and clear data for each one. Reboot and give it at least 5 min to rebuild library.
Prob need to clear data for these

What version of what kernel does this issue occur on? In October, the CM10 builds had issues with media server drain that coincided with kernel commits. 3.0.46 or 47 i think had those issues.
I assume its the official JB update, not a custom rom.

Requires more than that. Media Storage usually isnt the primary culprit. See my post towards top.

I've been having this issue for a while now on Frosty. I tried what Doc mentioned earlier, but it doesn't seem to work after restarting my phone. The only way I can stop it from draining is to go into battery and stopping the process.

If that didnt help, the next step is to factory reset and reflash.
If that doesn't work then itll be something on your sdcard causing it to hang/wig out.
It may be a corrupt media file, or just something on there it thinks is media and when it attempts to load its info into library it screws up. Im just guessing at this part, but if you do a complete clean install, all thats left is your sd data.
Youd need to backup, and reformat the sdcard most likely.

This wont help in my experience. I intentionally reflashed everything last night and left my sd card out, and it still does it
I've done tons and tons of experimenting with this issue over the past 24-48 hours and I was able to come up with a solution that worked for me. I examined the external.db file which is located in /data/data/com.android.providers.media/ and noticed that it scans all files on internal SD and Micro SD right after each reboot. I had a 1.6gb titanium backup folder on the Micro SD which was taking the scanner a lot of time to get through so I copied that to the PC and deleted it from my phone.
I also got rid of a whole bunch of other unneeded files like roms that were just sitting around taking up space. So now instead of my phone running max CPU utilization for 10-15 minutes after reboot, it only does it for about 1-2 minutes and settles down.
Thats normal behavior for it. Naturally the more data you have the longer it takes to scan. 10-25mins is longer tgsn I believe it hss to be, but the issue a lot if people are having is this process will continuously run forever! Causing 10-15% power drops in less than an hour!
All I know for certain is the couple of suggestions I posted in here have worked for others ive helped in the past, the first one I mentioned seems to work most often and has worked a few times for me. Obviously they dont always work for everyone. I just wish we could figure out the exact cause!

I FOUND A FIX! Apparently, I had 300 mp3s that needed fixing so I ran a program "Mp3 Scan + Repair", fixed all my mp3s and put it back on my sd card. Also, I removed all m4as and converted them into mp3s. This was a suggestion for how to handle mediaserver issues from ICS so I was surprised it worked for JB

Awesome dude. I also read somewhere that the CFQ I/O scheduler has more of an issue w/ media scanner than others. I'm not sure how true that is, but lately I've been running 2ghz as max speed w/ SIO for I/O Scheduler & interactive governor along w/ the other things I've done and I get less than 1 minute of CPU trashing after each reboot. I will have to try that program though to see if it can get me down to zero.

I dunno man, if that isn't happening without some 'aftermarket modifications', umm, I'd swap the damn phone. That isn't normal. I never get reboots unless I am overclocking on perf gov with everything maxed out...and that's pretty much it. If you are getting reboots just sitting there or dicking around on the internet that would be more than enough reason for me to take it in and swap it out...especially if you can reproduce the it for them.
Thanks for the replies guys, to answer your questions no I'm completely stock running stock kernel and it happens whenever I'm online or some apps will trigger it. I'd hate to restore but I think it's the only way
Ive had it a couple times.
It started after uploading app from market installing it while I was deleting one at same time
device crashed reboot took place.
From that point a had a couple reboots within days Touchwiz error displaying automatically going to phone keypad no escape from it.
I ended up doing factory reset fixed it all is well
did you by chance take an SD card out if another phone and pop it into that phone? if so, back up whatever data is on it, and try formatting it (if that cures the reboots, obviously something on the sd is corrupt and not cooperating with the system... dont restore anything from that backup you took after formatting) I would then try a facotry reset if the previous doesn't work. if the factory reset doesn't cure it, I'd swap the phone.

Thanks guys, I installed all the apps I could to the sd card. In other words all the apps were in the internal memory and that seems to fix the issue.

This has been pretty much been the most frustrating update process of my 4 Android devices that I have owned.
Hoping some of the sharp people here can help me out.
Buttons Not Working - About every third or fourth time I wake my phone my physical buttons do not work. I have to put the phone to sleep and re-wake (sometimes multiple times) to get my phone's buttons to work.
Excessive Battery Drain - Yikes!!! I have uninstalled all my apps, and it is still occurring. Any other ideas to figure out what might be causing this?
Constant 3G data movement - When wi-fi is off, my phone is constantly pushing 3g data up and down....non-stop!
Excessive Phone Heat - My phone is running like a furnace.
Now, I think the last three are probably connected in some way.

I am glad I am not the only ones with these problems.
It has to be a ICS function that is causing the excessive battery drain.
I currently have no non stock apps installed.
I have noticed that the battery ran from 100% to 25% but battery drain had no slowed considerably....maybe faulty logic in how they are calculating percentages?
The one I would really like to solve is the buttons not working, as there will be lots of battery related threads as more and more people upgrade.

The malfunctioning buttons have been happening to some of us on every ROM, whether it's Gingerbread or ICS. It happens to mine on stock GB or stock I'VE.
Just so you know, you can tap the volume Roche to wake up the buttons. You don't have to cycle the screen. Tap the volume button, wait second or so and you will see the capacitive buttons blink once... That means they've reset. Sometimes you have to do it twice.

JB has been known to use more battery than ICS(At least with the port releases) I've seen upwards of 65%
If you're rooted use betterbatterystats and see exactly what is draining it. A known source of major drain (for me 10% an hour) was an unknown service in /system/bin called gsiff_daemon. It has something to do with gps, but that's besides the point. On every rom I flash, I go in and rename it to gsiff_daemon.bak this will make it so it won't run. I have done this the entire time I've had a gs3 and never once have run into an issue from disabling this service, but I have saved my battery by doing it

I have a Note II that is around three months old. The battery would last around 1.5 days with normal usage.
Then, about a week ago, I noticed that it was not even lasting a day. Often 'media' uses more battery than the screen, which I have never seen before.
Last night, I fully charged it to 100%. I woke up 7 hours later and took the screenshot below - 49%! 51% used in 7 hours standby time. This cannot be right? Surely? I have noticed something going on with my SD card, where when I unlock the phone, it "prepares" the SD card. I had not seen this before.
Also, a strange phenomenon occurs where when I delete an app, it leaves a hole/gap in it's folder. (see screenshot 2). I cannot get rid of it. Any ideas?
Having the same problem. Mine used to get almost 2 days and after the latest OTA update "Media" seems to be using a ton of power. It seems to be related to scanning the media files. When I try to force stop the app, it just restarts itself. I thought maybe it was a bad SD card, so I tried a fresh one, but the problem is still there. Any ideas if this was introduced in the update and whether or not we can stop the process. I am not rooted on stock ROM.

Download media scan root from play store. It will disable media scan and you can re enable it with just a click If you have new media files. But root is required for this app.
Alternatively if you do not have root. Try format the sd card. It might solve the problem a while but not sure why it comes back again. It s a known issue for jellybean

Nope, still on 4.1.1.
Also, Google+ is now using a fair amount of battery too, usually around 10%. Strange when I don't actually use G+...
I tried a new freshly formatted SD card and today I am at 70% after about 12 hours. This is what I was getting before the upgrade. Will keep everyone posted if it happens again. Before the new card I also noticed the system was unmounting and remounting the card frequently. I am sure this is what was causing the rescans. It was only 2 months old so perhaps the card was bad.

Hi,
I am wondering if it is normal that wifi speeds slow down after a certain time. My wifi at home can reach up to 22 Mbps down and say in a couple hours for example it would drop to 10 Mbps. Immediately I would restart my phone and it would be back up to normal speeds of 20ish Mbps. I do multiple back to back tests on speedtest.net app and my wired connections and other wireless devices are consistent.
My wifi does not disconnect and it has no problems connecting to other souces. At work i have the same wifi issues.
I have a Canadian Rogers Note 2. I am rooted and flashed to cleamrom 4.0.5, fully wiped and reset before flash with twrp. I have tried turning off power saving mode during the slow wifi transmissions and still have this issue,
I am lost as to what to do. Any advice would be appreciated.
