Android System taking up 80% CPU

[Guest womble_sanfran]

I am on the stock ROM and my phone has gone laggy, it seems that the Android System is taking up at least 80% CPU. How can I work out which part of Android System is the culprit. I have tried terminal commands like ps and top and they just say it is the android system but I want to know which part of it!

I had this same issue a few months back and it turned out I had replied to a text which came from an invalid number and my phone was constantly trying to send it and failing, when I deleted the text the phone started running quickly again.

And yes I have tried turning it off and on again! :D

Thanks

Here is an extract of what I get when doing 'top':

User 12%, System 87%, IOW 0%, IRQ 0%

User 41 + Nice 0 + Sys 277 + Idle 0 + IOW 0 + IRQ 0 + SIRQ 0 = 318

PID CPU% S #THR VSS RSS PCY UID Name

1190 93% S 54 251752K 49732K fg system system_server

i had a similar thing where android system was making the phone laggy. I managed to track mine down to media service under the android system and then finally found out that if I had any AAC PLUS MP4 files on my memory card the phone became laggy, even if I NEVER tried to play them. I re-encoded these to AAC and all was fine.

Have you tried unmounting your SD card to see if that helps ?

How did you track it down to media service under the android system? Did you use an app to tell you that?

I will try the unmounting trick.

The phone appears to have fixed itself now, I still have no idea what caused it.thanks for the system panel tip, it seems like a great app.

It may be the same problem others have had. Try:-

This has happened to me again. I have tried 'top' and it says that system is taking all the CPU, I tried covering the light sensor and it didnt help, I tried numerous reboots, I tried dismounting my SD card. Also system panel just says it is 'system' using the CPU so it doesnt help much at all.

Is there anyway to find out which part of system is using the CPU?
