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.

Hello,
I am owner of HTC P3600 from last 12 months and i used custom roms too all was working fine and before 2 days i found that whenever i leave the HTC for few hours it hangs and when i press the standby button to wake it up nothing appears on the screen and i have to reset it to start it again.
Updates:
Ok i re flash the Hard SPL, Radio and Rom and until now (in last 24 hours) it don't hangs.....
Update 2: I think the battery is the problem as the battery time is decreased from 3 days to just 1 and a half day and it freeze now while charging....
Any solution? anyone experience the same problem?
Help please with your views...............
I have a similar problem. My HTC started crashing after a rom update. However, i think it is not crashing due to software...
Well, the software is more CPU demanding, so it heats more than before. Also, i started using backlight properties set to high (i need to set to low again), which again highly heats the PDA. Finally, when charging the battery tends to get very hot. All this put together causes the CPU to overheat and crashing.
At least, from my experience, when it crashes it is always very hot.

Sounds like a radio rom problem. Try to reflash radio.
Thanks for the advice!
I will reflash the radio rom.
If it solves the problem i will update my post here so everyone else knows how to solve this kind of problem.
it helped ? reflashing the radio rom ?
lol you ****up your phone hahahahahahahha
No, it did not helped. Probably it is an hardware problem.
The pda was intensively used connected to the computer, because it was used for software developing.
I think it is broken, hehe.
Hi, ever since yesterday i been having a strange little problem; All my music files and photo/Videos are gone from my music player and gallery apps!.. I check the SD cards (both internal and external) all the content is still there except it wont load it! even when trying to access it with a different app (such as Play by AOL, Amazon MP3 player, Winamp, etc)... also when trying to switch my ringtone or notification sound it clashes! I tried rebooting the phone, downloading apps to re-scan my SD card and so far no luck...
another strange thing that stated happening yesterday also (I think it was around the same time, it sure seem like it) my phone started draining the battery really quickly. it gave me about 5 hours of life from 70% to 0%. this is waaay to quick! it usually gives me at least twice if not triple this!...
I have also notice that phone starts getting really warm when trying to load the music and gallery app...
has this happen to anyone else? or any suggestions? would really appreciate some helps... thanks...
Did rebooting help anything? I had a weird thing just the other day where all music and my ringtone were playing at really high speed. Rebooting fixed it, though I wonder what the issue was. There are programs that log cpu use by apps and things. For the battery issue I'd try one of those or go into your Battery Monitor in settings and see if you spot any apps that are eating all your battery. System Panel also works. It will keep a week long log of your cpu usage among other things.
You do anything else right before this?
Install any apps/p-roms anything like that?
Try a battery pull?
Try watchdog for a cpu monitor, it can notify you when an app is using excessive cpu.

no, rebooting didn't help. I tried it multiple times. Tried pulling the battery leaving off for a couple of hours. Nothing
OK, i tried looking at the battery manager and it said that Media was taking up 35% of it!!! I tried force closing it. And after that some of my music became playable. But still it was very sluggish.
Unfortunately I did update alot of apps the previous day. So it may be attribute to one of them... but my phone is pretty much stock. Only with side loading enable... so no custom roms.
Thanks for your feedback, ill keep trying a see what happens and of course post my results for future reference..
PS my battery drain at an astonishing rate!; from 80% to 0% in less about 3hrs...
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?
Overheating on my Galaxy S4.
I have a Galaxy S4 for about a year, I have this problem almost since I bought it, but it appears and reappears, so I let it go.
My Galaxy S4, using WhatsApp Music and the CPU temperature rises to just using these programs 45-50ºC
Using only the poweramp the instrument reaches 65c for no reason.
Using browser is hopeless, the device rises to 50-70 degrees and finally restarts or shuts down.
When I bought the unit in the first week I realized that he was heating a lot, but did not reach this temperature (50-70) normally.
I read in various forums that the normal temperature of the Galaxy S4 units were 35-56c
Recently, I downloaded a few albums of music and some pictures on my phone that day he shot and started this strange behavior, and following the same steps bellow, the problem still persists.
I already own a Galaxy Note and I have witnessed the bug "AndroidMediaScanner".
I did all the steps (exeto formatting the MicroSD, I recently formatted to exFAT SD) Until I checked the status of the reading process of media using the Android ADB, there was nothing abnormal ..
Even without the memory card, few files in SD (just applications) the problem still appears.
What do you think? It may be a hardware problem that requires replacement?
It may be the battery?
It may be the ROM • (when the OmegaROM use a series of modules Xposed)
Recently reinstalled the ROM and the problem still persists.
I read in a blog that the DS Battery Saver could be giving conflict with the manager's native battery used in the Galaxy S4, I uninstalled the program, yet the problem persists warming.
Connected to the USB temperature suddenly increases to 65c without any reason or use.
What recommend?
Sorry for the English. I used Google translator.
Maybe i attach prints.
My initial thought would be to get a new battery. Becaus it jumps so drastically when you start charging it. You could also check your battery connections. Make sure they are free from dust and corrosion.
Hey Girafa, missed u man. :/

Ever encountered moisture near my battery (cover).
I try to buy a battery when you can.
But do you have any recommendations?

You have to find the "service" that is turning in background....
If you mind it is the AndroidMediaScanner, I can say from experience ( it was killing my battery in less than 5 hours)
I stopped this issue (flaw) by cleaning one by one my Music folders and deleting those empty or having no music file in it ( that sometime comes when you clean a directory from the music player interface) .
then my phone turning back to normal temperature state.

I said in the text that has nothing wrong with MediaScanner Android. I used the Android Debug Bridge to verify this and it appears to be normal.
The application showed 10% CPU usage when the unit was starting.
I used OS Monitor app (it shows up the processes of the Linux kernel and user) in order to find some buggy process that was doing it.
I removed 4GB of external memory file and checked the Android Debug Bridge MediaScanner if the process had been stuck at some file storage.
There was no error in both stores.
I witnessed this primary failure of the Android system twice on my old Galaxy Note.
Thxz for reply.
whats the solution
So hello anybody seeing this thread and thanks for considering even reading this
so my phone now is acting crazy , this started to occur after i tried to return to the stock firmware but two things happened while installing the stock firmware
1st- i got an error copying file called "HIDDEN" error reason = size was too big so i removed it from the firmware file and installed it and it installed successfully then i restarted it to install twrp and format data from there so i wont lose my stuff on the phone and that leads to the second problem
2nd- i wasn't able to access any partition and i mean all of them [SYSTEM-DATA-CACHE] so my only solution was to change the file type and get it back to ext4 to kind of force them to be reformatted and that was successful too so i re-installed the firmware and then this problem arised
my phone's CPU usage was so high like 95% all the time and it was running on 2150mhz i think like all of the time and my battery was getting like killed in a matter of 2 hours, please have in your consideration that this was a freshly installed rom that i didn't even install any apps on it yet
so i thought maybe this firmware was bugged so i changed to NX's team s8 rom just to find out the same problem was happening again but the only difference is that when my screen is off it goes into deep sleep like normal but when i open the screen and unlock the phone the usage goes up again frome idle to 95%-100% so i thought maybe touch boost or CPU hotplug so i tried every hotplug avalaible even tried disabling them along with the touch boost but nope my 4 cores are all running and killing my battery so i thought maybe this rom too so installed linage os and RR just to find out the same problem was still there when the screen is off my phone could do like 14 hours easily on battery or more but when i open the screen it immediately goes to 95%-100% usage and my phone gets hot till like 70 degree so i changed the kernel too
so did anybody face something like this before or could at least tell me what's wrong and how can i fix it
and tell me if it could be like anything related to my phone's hardware like faulty hardware or something related to bootloader -modem etc.
please any response would be good and appreciated hope someone could help me
