CPU usage never goes below 30%, why?
- I'm pulling my hair out trying to figure out why my CPU usage is so high. I'm losing about 10% battery every 20 minutes so I can never be too far away from an outlet. The phone constantly stutters, especially when scrolling through anything.
I downloaded a usage monitor app but it isn't helping at all. Apparently the CPU hogging app is hidden! See for yourself:
Exchanged my S III for a new one but it also has the same problem. I've uninstalled all unnecessary apps and removed every widget from my home screens but that didn't fix the problem. Even after a fresh reboot the CPU still hovers around 10-20%, with constant spikes into the 50s.
I'm new to Android but this doesn't seem normal at all. Help!
EDIT: Here's a list of the few apps I've installed. Lookout claims they're all safe:

Try checking the CPU usage of system processes with your usage monitor app or with an app like Watchdog or System Tuner.
For more info try Googling the Internet for "kworker load"funkylogik likes this.10-24-2012 05:19 PMLike 1 - Watchdog is giving me the same results as Usage Timelines: system processes using almost 0 CPU, but user processes always hovering around 30-40%. Then when I look at the list of running processes, the numbers don't add up to the usage I'm actually getting. Your Google suggestion didn't help much.10-24-2012 05:42 PMLike 0

- I can tell you that if you used "Advanced Task Manager", you could auto close Dropbox because that doesnt have to be constantly running in the background, so thats 6% off right there
And what is "Security Storage"?
Your WiFi calling (The icon with the blue telephone on ur notification bar) could also be taking some CPU, do u need that running all the time?funkylogik likes this.10-24-2012 06:11 PMLike 1 - again you have more patience than me bro
suppose it could help some other users in future.

What do you see if you do a "top' in a terminal emulator?
-Load a terminal emulator app
-Enter "top -m 5 -n 1" without the quotes to display the top 5 processes one time. You should see information including the percent usage, fg or bg (foreground/background), the app user ID or "system", and the process name
something like:
User 10%, System 4%, IOW 1%, IRQ 0%
User 57 + Nice 4 + Sys 26 + Idle 515 + IOW 7 + IRQ 0 + SIRQ 0 = 609
PID PR CPU% S #THR VSS RSS PCY UID Name
378 0 6% S 84 382000K 50824K fg system system_server
28426 0 1% S 16 281080K 31244K bg app_202 com.mobidia.android.mdm:remote

Very strange.

As you can see, those top five add up to 27% CPU usage alone. Whatever this "system_server" is appears to be the culprit (well, that and "Security Storage"). So now what?
And yes, I am appreciative of the help you guys are giving me; SΛMSUNG & T-Mobile's solution are to exchange the phone, but like I said I've already done that! THANK YOU x1000 for your suggestions.funkylogik likes this.10-24-2012 07:05 PMLike 1 - It's odd that top shows only 13% being used by User, not 44%. Top and the monitor apps should all be showing the same data provided by the kernel.
Of the 13% app_166 (the terminal emulator) was using 5% in the foreground which is reasonable, and LiveClock was using 5% in the background which sounds kinda high but shouldn't be a problem.
Have you powered the phone all the way off and back on?
High data usage may be what's draining your battery. An app like "My Data Manager" should show what is going on with data usage (in My Data Manager check "My Data Apps" on the second screen).Psythik likes this.10-24-2012 08:39 PMLike 1 - Or you can go into Data Usage in the Settings on your phone and see a timeline graph of data usage and totals for each app. Click on an app to see its timeline and a breakdown of foreground and background.10-24-2012 09:43 PMLike 0
- Ah, the classic "have you tried turning it off and on again" line. Takes me back to my I.T. support days.
I've decided to test your theory by taking it easy on the web browsing and app downloading for a little bit; CPU usage has gone down to a more reasonable 3-8% but I'll have to do some more tests to make sure the two are actually correlated. Looks like I'm gonna have to invest in a high capacity battery. This one looks like a good choice save for the fact that it's gonna turn my phone into a fatass and thus my case won't fit anymore. Hopefully someone will make a 4000+ mAh battery that doesn't increase the thickness of the phone.
Well thanks for the help, people. I guess I'll just have to get used to owning a phone that doesn't hold a charge for an entire day.10-24-2012 10:12 PMLike 0 - In the past my phones would overheat and I'd find the CPU pegged high over 90%. The culprit was always the stock Android browser, even if I wasn't using the browser. I switched to using the Maxthon browser and never again have had a high CPU usage problem. But web browsing with Maxthon still heats my phone and drains my battery.
Have you considered using one of those external battery booster packs?10-24-2012 11:16 PMLike 0 - That 'Security storage' process is very puzzling - is your phone encrypted? Or do you have encryption enabled for your SDCard?
I hate to suggest a factory reset, but it may be worthwhile doing that and then checking your CPU usage before loading a bunch of stuff. Then just monitor your stats as you load applications - it's something that you've loaded or enabled because this isn't the default behaviour of this device.
Edit: BTW, the next time you need to list the applications you have installed you may want to consider https://forums.androidcentral.com/e?...token=RcmmRn3Q - it's much more straightforward than a bunch of screenshots.

I gave Chrome a try and it was the same story. Opera Mobile was nice but too outdated. Finally I gave Firefox a try and it's been smooth sailing ever since. Funny how FF and Chrome have switched roles in terms of performance compared to their PC counterparts!
Lookout was contributing a great amount too. I'll have to find another device recovery solution. Anybody have a suggestion?
Still have no idea what the security_storage thing was about but it doesn't seem to be an issue anymore. I'd love to use encryption but I like my pattern unlock too much.10-25-2012 05:14 PMLike 0 - Android Lost is pretty good and uses no battery mate

- OWybPPgOGeek MomFor the future, I suggest using Elixir2 for looking at CPU issues. It has a "top" screen built in and you can add a little CPU meter to the task bar to keep an eye on things. It does a ton of other stuff too. I find it invaluable to seeing what's actually going on.Life-Is-Good and Psythik like this.10-26-2012 07:53 AMLike 2
- I am having similar issues. I have a Droid RAZR on ICS, using Chrome. I also have Watchdog lite. I get 40 or 50 alerts indicating that G+ is overusing the CPU. If I kill G+ it starts back up in seconds. Any suggestions?12-11-2012 09:42 PMLike 0

I tried that and it worked (ie CPU alerts from watchdog stopped). I've not checked if they have fixed it yet.12-12-2012 12:40 PMLike 0 - I'm pulling my hair out trying to figure out why my CPU usage is so high.
