None of the system monitor apps I download show process CPU usage. I have some rogue app or process ramping up CPU frequency for no apparent reason, heating up my phone and killing my battery.
This wasn't happening prior to rooting and installing a custom kernel, but I can't exactly blame those items as the cause, and I'm not using any weird apps either... so really confused as to why this is happening.

Hello,
I find things very funny on my phone let me describe. This happens on both opendesire 4.0.25 and defrost 4.9 . I am downloading defrost 4.7 now to see if the problem solves. This is it, my phone clock speed is always at 998MHZ and the CPU usage is always at 100% . I realised that is why my phone always got hot and the battery drains fast. I hope someone could give me a solution, or is it the new kernal that is giving the problems?
Thank you.
On Defrost you can try a different kernel directly from the Defrost setup.
I am now using HAVS 1113and the phone works great and the battery life has increased significally
Thank you for your reply
but that is not the problem. This is, my CPU usage is always at 100% (checked with many apps) also the CPU setting is ondemand which means my usage being at 100%, makes the clockspeed always at 998. The process that took up 76% of the CPU was named android.process.media or something like that. Anyone knows what it means and what I am supposed to do now? How am I to disable the process and what process is that? How can I disable it?
Thank you and I'm hoping for more replys its quite upsetting to have your processor running high all the time
Sounds like a background app is stopping the Desire going into a sleep state...you might have to reset the phone and add 1 app at a time to see what it is...
install Android System Info on your Desire and take a look at the tasks list.
There press the menu button to sort the list by CPU load.
The total CPU load should be around 10%, which gets consumed by the Android System Info process itself, and a small amount by Android System Info.
Hi guys,
My phone is constantly "awake" despite rarely even turning on the screen.
Would you know what could be causing this?
I'm currently running Caulkins rom and whatever kernel it came with.
My battery life is ~15 hours so I dont think it's affecting my battery too much.
Either way, is there an app that can tell me whats causing the drain?
First of all, to see if your CPU is sleeping properly when the screen is off, download CPU spy… it is an app that gives you total time the CPU has spent in each scaling frequency available.
Then download watchdog, this app tells you which programs are polling the CPU for usage.
Then download “better battery stats”.. this app tells you if there are wakelocks.
With those 3 apps running at the same time, you will find out any abnormalities in your system caused by applications.
Side note – disregard info that either of the apps report about each other (obviously)
All of a sudden my CPU is running at 100% non-stop. Using Trickster-Mod I can see this and my phone is extremely hot and my battery drains in about an hour.
I used better battery stats, CPU Monitor, GSAM... all show normal battery usage, no apps or processes using more CPU or battery than normal. I'm at a loss, anyone have any ideas?
Thanks,
Justin
Chances are it's a rogue app. Process of elimination, remove anything you've recently installed.

What if anything have you changed using Trickster? I'd maybe uninstall that and clear cache/Dalvic and do a couple reboots and see if it's still acting up.
Of course there's the Factory Data Reset option too.

Thanks for the help guys. I tried tracking down an app but I hadn't installed anything recently, just some updates, I froze all of the possible offenders with Titanium Backup and still had the problem. I hadn't made any changes to Trickster in a long time but I tried that and it didn't make a difference either.
So... I ended up backing up everything with Titanium Backup and installing SkyDragon ROM... that fixed the problem.
Thanks again for taking the time to try and help.
Hey guys, need some help. I have an AT&T H810 rooted 10o. My little cores seem to be running full out at 1440mhz even though my governor is set to Interactive. This is causing it to heat up incredible, to 70c+, and is draining the battery quickly. It seems to have only started occurring in the last few days! I can run it in powersave governor which fixes it to 384mhz, and it fixes the problem, but I don't understand why it is running at full speed under interactive now. The big cores do NOT have this problem AT ALL.
I've removed any apps I installed during that time, cleared my phones cache, cleared the memory, I have tried running it in airplane mode, I've looked into what apps were running and it seems to be very few. Turned location off. I've tried freezing the play services because I have been getting a very intermittent force close. I have also tried to disable all xposed modules, and used avg to scan for any malware. Possibly init.d? Possibly the new xposed v79? I'm at a loss as to what is causing this!
Does anyone have any other ideas as to what could be happening?
There's always the good old factory reset if everything else fails.
Just asking the obvious but there is no offending wakelocks or anything that sticks out in the battery usage stats?

Battery usage Android OS is highest at 33, followed by screen at 16%.
Wakelocks, I seem to have them under control with amplify, and I don't see any new ones.
Question about factory reset, I am not near a pc for the next few days, will it cause any problems with xposed or my rooted system image, and basically what can I expect with it? I came from a M8 where with custom recovery I was pretty fearless with being to wipe and refresh, can't do that here.
Noticed that disabling 2 of the little cores with kernel auditor really helps with the heat buildup of the phone with not much slowdown

Doesn't solve why it's running at full speed, but I'll keep that in mind.

Personally I never done a factory reset myself yet so i cannot comment.
For the most part it does look like you have something to work with seeing Android OS is taking up the most battery. The hard part is tracking down which process. I'm not the best at this so maybe someone else can chime in. Try taking a look at your currently running processes and see if there's anything odd
Well, after a few factory resets which did not affect xposed, I was able to resolve it to where the cores now return to 384mhz idle. It was something that was installed, and it took 3 or 4 resets after restoring my app backups, and I'm still not sure which app was the culprit. I'm possibly wondering if it was the Amplify module
Sorry for bumping this. I just suffered from this problem and it seems for me it was antutu. For some reasons it was running the background keeping the 4 small cores at 1,2-1,4 cuz constantly. I stopped it and now it's back to normal. Just wondering why it started itself in the first place.

I even broke my phone with App Ops trying to figure it out, disabling wake permissions for most apps which caused FC's and even reboots. I have since restored all permissions but I still get FC's whenever I leave an app or switch out of it. Not sure if it's really crashing, but I get a FC message every time. So much so that Substratum turned off its theming for Files because it "crashed" after every screenshot was successfully uploaded to this post. Btw I just removed CrossBreed Lite and it seems to have helped. So far no reboots doing the same stuff that caused reboots! Not sure why it caused problems though. I used it for a few days with no issues.
Anyway, back to my battery woes. 30-40% kernel system usage. Why is this happening? Even Snapchat which is abusing wake locks is nothing compared to kernel system.
I'm running the latest build of AIM 8.1 with EX Kernel. I have just visited the other thread about tweaking governer values to optimize battery life so I'll report back with results although I doubt that's relevant to my battery drain.
I've Googled quite a bit on the subject and it seems that each case is different. Usually caused by a certain bug, although a lot of people say it's "normal" which I strongly disagree with.
Update: optimizing the CPU has definitely made an improvement, but the kernel battery drain still exists.
Could it really be pick up to wake and wifi search behind the drain? Isn't this phone supposed to have a sensor hub that allegedly allows for all sensors to constantly be on while using minimal power? I never noticed this drain on any other phone with both of these features on.
Anyway, I disabled pick up to wake and I'll start trying to remember to turn off wifi when not in use.
I think you're trying too hard and running a bunch of stuff. The kernal usage looks about right. I wouldn't run Gsam and BBS at the same time. They can fight each other. What makes you think there's a problem? Nothing jumps out at me.

I also can't see anything out of the ordinary, except this one picture where it shows the phone being active while dozing. I don't know how to understand that because I don't use that app, maybe I'm reading it wrong. What does Android's built-in battery monitor show? Is it dozing properly while screen is off? What is your average SOT? Is your mobile signal strong? I'm also using AIM 8.1+EX combination with satisfying results. Is your radio up to date?
maybe Wakelock Detektor or Greenify can help you.
And if you currently have things crashing all the time, start with a factory reset. Much easier to diagnose the cause when the apps aren't doing random stuff.
