Been noticing high cpu usage from android.process.media
I'm wondering if it has anything to do with the Wanam Xposed sdcard rw fix and the note 4. During the time the process is high if I UNMOUNT my sd card my cpu usage corrects itself. Gonna try disabling the fix and seeing if it still does it.
Anyone else experiencing this?

Don'y know if anyone observed this or not:
My N1 with a2sd enabled consumes more power than without. This shouldn't come as a surprise to anyone as need to access SD requires additional power.
Anyone observed similar pattern with a2sd?
What does it have to do with app2sd?
That just points out what applications you can move to the sd-card.
You can do that without app2sd too...
Mod edit: Let's keep it friendly here, guys.
LOL I have not notice but I have notice a crazy lag to load icon stored on the sd card maybe I need a better class. I been doing ok on battery so far down clocking to 700mhz and flashing it to MIUI but I wouldn't doubt my app2sd drains battery since is probably always scanning to free cache.
Let's keep it friendly in here, guys.
Personally I haven't noticed any battery drain with the Froyo / Gingerbread Apps 2 SD / Apps 2 USB Storage. While that's a little different than the Apps 2 EXT, but I would imagine them both to not use much power at all. Both internal memory and USB storage use NAND flash memory, and it would be reasonable to assume that they use similar amounts of power.
Spx2000, you could have some issue in your particular installation. Perhaps try wiping cache and Dalvik cache and/or do a full wipe and reinstall your ROM.
I think there is a problem with App2SD that seems to have started with an update a few weeks back. In fact, until I started reading the comments here, I had no idea that it might be the cause. My Nexus One has had extremely slow performance and a slow battery constantly for the last month or so. It all started at once. It was around the same time as the 2.2.2 upgrade, but I swore it started a little earlier. Today I went and turned off the option to check downloaded apps in Apps2SD and it seems that my Nexus is back to its old form. Something must be wrong with the App2SD feature that scans downloads. It doesn't show up as the App2SD process slowing down the phone, but you see system load from processes such as init. If you have the problem, I recommend turning off the App2SD option which checks downloads to see if that eliminates the problem.
it is true that if I use the app in SDCard consume more battery?
I've rebooted the Tab a few times, but in OS Monitor, the "Download" process is running all time time using at least 30% processor!
What's the deal; anyone know? I'm unrooted and running the latest Tw update.
Thanks!
Ended up being MediaServer running. I stopped in in Manage Applications->Running. I stopped it and my CPU went to normal levels. My home screen responses got alot better too.
I vaguely remember this issue on my Samsung Fascinate too.... MediaServer always got hung up on some type of sync'ing.
I'm having the same issue. So what is actually causing this? Any way to disable the mediaserver all together? It seems to keep re-starting itself eventually.
I haven't found a way. It doesn't affect battery life as far as I can see, but it lags my Netflix if its running because its already sapping up 50%+ CPU.
Yeah, I've noticed that the tab gets laggy when it's running, and it speeds up a lot when I kill it in OS Monitor. That's my main reason for wanting it closed. It doesn't seem to affect battery life while the screen is off, but when the screen is on (such as reading an ebook) it absolutely reduces battery life. I just tried freezing it in Titanium Backup but it resulted in all the gapps (such as Gmail) crashing and refusing to open after rebooting.
I also noticed that on some boots, it's DRM Protected Storage Content rather than Download Manager. I just froze that instead and haven't noticed any issues from it yet, but I won't know for sure until rebooting.
I'm having a very similar issue, though it's process.android.media that is causing the problems. I have to manually kill the Media Storage service several times per day. It's quite annoying.

This Media application is what calls the Download Manager service. Killing this app also kills the service that's using alot of CPU processing.
I've noticed that I get a lot of errors in logcat pertaining to the sdcard. They are usually right around the time that a media process starts up, but I have hundreds of them throughout the log:
E/Environment( 1250): getExternalStorageState/mnt/sdcard
E/Environment( 1695): getExternalStorageState/mnt/sdcard
See attached screenshot.
It appears something is wrong with reading the sdcard, and I'm guessing this is maybe causing the media process to hang eating all the cpu?
I have a i9505 and I updated to android 4.4 and I have an issue with high CPU usage, I may have had the issue on 4.2 too but I am not sure.
Occasionally I notice high CPU usage and my battery life is quickly starts falling. I see two android.process.acore using a lot of CPU and I cannot kill them. When I look at them they are both com.android.process.userdictionary and seem to refuse any attempt to end the process. The only apps I had used since booting the phone was whatsapp , gosms and email app (only to view and not reply to any emails)
I have not loaded any new applications and I cannot see what has called the userdictionary process and why it keeps coming up and using high CPU.
A reboot of the device solves the issue, but it will recur again at some point.
Help?
OK so this is getting worse now.I have had t reboot the device several times today to get rid of these acore issues.
pls can someone help?

I'm having this problem with my NoteII LTE (GT-N7105)
Trying to find a solution - but no luck thus far.
Did you solve the issue? krtccd is always on top with up to 40% CPU usage on my Samsung Galaxy S4

I have the same problem and I don't know the exact reason why this happens, but it is due to a mess in the swap activity of the phone. If you have a rooted phone with a kernel that let you enable or disable zram (like googy max) so try to disable it.
I think that some memory leak or some app put the memory in a bad state screwing up the swap process.
The problem should be temporary stopped if, during the high cpu activity of the krtccd process, you make a "close all" from the multi tasking manager of your phone (accessible holding the home button).
I know it is a late reply, but this could be useful if someone search the forum for a solution.
mannybiker, many thanks for your reply!

could you recommend some app that detects processes with a high swapping activity?

No vak, unfortunately I have not found any app that could show me the zram used per single processes. I kept the same rom with the same config for 9 months and never experienced any problem with krtccd, then suddenly it started to happen so I think this could be related to some update the phone has made to some of my apps. The only thing I could imagine to do is a debugging period making a titanium backup of all the apps, uninstall them all, verify that the problem is solved and start restoring them periodically one after the other seeing what happen, but for the moment I have just completely removed the zram from my kernel option. It is still a controversial feature that increase available memory but also cpu and then battery consumption.
I am not a Linux expert and I have not tested this on Android, but on Linux you can try to discover the swap usage per process with something like that:
Code:
for file in /proc/*/status ; do awk '/VmSwap|Name/{printf $2 " " $3}END{ print ""}' $file; done | sort -k 2 -n -r | less
HI all,
I seem to be running into random, occasional bouts of battery drain on my phone (i9500). I was on ozscan rom earlier and now switched to prism barebone. Whenever my battery starts to suddenly drain, I notice that the process 'kblockd' is eating up the cpu. I've tried looking around to find a root cause to no avail.
Now, if I understand correctly, kblockd is responsible for disk IO? could this be an issue with my external/internal memory?
can anyone help me pinpoint the issue? I will try to capture a logcat when this happens again. A reboot always solves the problem generally. I will try pulling out my external sdcard the next time it happens
Thanks.
When i woke up today trying to turn off my alarm, i noticed that the phone is choppy and lagging heavily which is very unusual. Initially i thought some apps are updating but this lagging never stopped. So i used the system monitor in FKupdater to check if the cpu is running high, but instead i found out that the disk i/o is constantly running at full. I did some findings and currently there is no per-app disk usage monitor so i don't know what app is causing this. My phone is almost unusable now, can anyone help me with this?
My Nexus 4 is running on older version of ParanoidAndroid which is 3.69.
Android version 4.2.2, and latest franco kernel.
