my cpu frequency is stuck at 1.79 gghz and this is why my phone is lagging and heating and draining battery .
is there any way to check what is spiking the cpu so much ?
i checked in cpu process app and it says system server is taking the cpu .
And in my battery stats the android system is at the top.
I have done factory reset 4 times still the same issue.
Help appreciated .
Thanks
This issue gets temporarily solved by restarting the phone but after a few hours its still the same.

After reading a lot of battery drain threads on this Samsung Galaxy I9003 subforum i have a doubt:
The recommended solution is to install a clean android 2.3.4 rom?
In my case the phone came with froyo and after a couple of months i decide to upgrade up to 2.3.5... anyway, about one week the phone starts to constantly heat up on stand by mode without 3g or wifi activated and off course the battery starts to drain :S on battery stats i can see the bigger consume (about 62%) is related to stand by mode :S
I try :
battery calibration
factory reset
wipe
reflash 2.3.5
flash 2.3.6
But sadly the problem persist :S
Todayi installed CPU spy and i got a big surprise when i saw the stats of CPU speed, most of the time turns to 1000mhz , like i said the phone it's ond stand by mode with no 3g, wifi connections activated :S
Also i rooted the phone and installed setCPU to limit the max speed up to 300mhz, with that i can see the phone doesnt heat that much (compared when it runs at constantly 1000mhz) but still works at constant 300mhz whatever i do...
I really hope that the solution is to reflash 2.3.4 (or maybe lower?) firmware
Thanks for share all your knowledge and help people like me
If that the case then its an APP. You surely have an app that avoids your phone to go to sleep.
Thanks for your attention and time, i hav running setCPU (at barely 300mhz) and now the CPU temp is always at 32°C also i installed Watchdog lite and doesnt show any program doing an excesive CPU usage :S
Really i have no more ideas of what to look at
Yesterday at night i was reading a lot of drain battery related post (all the threads i found basically) and do the following:
Enter to CWM recovery menu > Advanced > Wipe dalvik
Also i select the ondemand settings for setCPU
Now the phone it's all the time on stable 36°C but sadly my battery still is drained (probably on deep sleep) Most of the time the processor is only at 300mhz and looking the battery stats android system and screen use an average precent (42% for display 23% for android system)
From a full charge (over a powered off phone) after 4 hours the battery has only 40% of ramaining charge and the phone it's on deep sleep (this phone today it's used only for make and receive calls, so no internet connection is activated)
No other people are facing this issue?
Hello,
just installed CPU-Z from the app store which shows a constant 30-40% CPU usage. killed all tasks with task manager, but still doesn't change.
Is this normal or anyone else experiencing it?
Running Stock HTC Android 4.0.4
Cheers
Mine is running at about 10-30 %.
One S (S4), Stock rom 4.1.1 (Lastest)
Do you have any problems with your phone?
Something to think about: your CPU will adjust its frequency depending on the load for energy management. For example: if your doing nothing you could be running at single-core 128MHz. So maybe it shows 30%, but it could very well be 30% of 128MHz(in short).
So those percentages do not necessary mean your phone has a problem.
My battery life is aweful. I can get around 2-2,5 hours of screen on time during a day...battery seems okay though. might have to do a factory reset or flash some custom rom.
Does anyone tell me why my phone runs at the highest frequency?
Even with all apps closed and even after restarting it. Also the WiFi consumes battery when its turned off.

Starting a month and half ago my LG Nexus 5 would get hot near the camera (Where the CPU is) and drain the battery unusually fast, even without an active app opened, now I can not keep it on outside because of the drain and even if it stays connected to a charger, it slowly builds a charge because of the drain.
I recently changed the battery and the problem continues to persist.
This started happening around when I went over all the settings in the phone and apps, I fear I might of turned on something that is causing it in the background but I can not figure out the exact problem.
Please help.

Check the frequencies of the cpu, sometimes the minimum value gets stuck to a higher than needed frequency.
You can do so by using Kernel Auditor (root) or CPU-Z. Obviously if they're higher you'll need to set them lower, 300 MHz is the normal minimum freq. If that is not the case then install Gsam Battery Monitor and enable extra stats, you should be able to figure something out with that one app.

thank you, it was the outlook app going rouge
Hello to all of xda-dev users. I got problem with my Galaxy s6 Active smartphone. One day it's just start overheating and draining batery very fast, just about 1% per minute or two. I have search many threads over many forums for solution and didn:t find it so i ask here, maybe someone will help me.
What i have noticed that overheating is caused by processor (sensor exynos-therm) while battery stay cool. I have did a factory reset few tmes but it didn't help. I have flash a new rom from this forum, upgrading from android 6.0 to 7.0 but it also didn't resolve the problem. I have no ideas what to do and where to search to find reason of overheating. While device is running, all monitoring software shows minimal activity and processor usage, anyway the processor seems to overheat up to 80C (almost 180F). Please don't say it is normal cause it didn't work that way before that malfunction. I hope someone will help, thanks!
To start...
Run the monitoring software as root? Reading the CPU usage of processes might be restricted without it?
CPU clock is lower with thermal throttling and doesn't look like heavy usage?
GPU?
Persists with wifi off?
Check for wakelocks/CPU background time, and it's the process at the top?
