So I was about to do a benchmark with system monitor open and when antutu started, only 2 cores would turn on. I exited out, and began going through settings, power save was off, I have no cpu apps and I'm not rooted. I decided to reboot and opened system monitor and all four cores were on and active. Any idea what might have happened?

Perhaps it entered into some power saving mode that we don't know about? (Other than the one in the quick toggles)
What was the battery percentage at?
75%. Temperature was normal and two cores were allowed to go to 2.3 so I don't think it's throttling. I have developer options enabled, but nothing changed (it was just to check out the options)

My Note can be laggy in random situation and I am trying to figure out the cause of it. Some of the RANDOM lagginess happened in the following situation:
1). Turn ON from sleep mode --> open built in Browser --> hit "Back" button to quit Browser, Note lag for about 2-3 seconds before the operation is completed.
2). From Home Screen --> click on "Application" to bring TouchWiz app list --> click on a "Folder" --> Note lag for 2-3 seconds before opening the folder
3). Open an application (ANY application) --> click "Back" to go to the previous app screen --> Note lag for 2-3 seconds before the operation is completed.
So you see, in some cases, the Note is really fast and in other case, really laggy.
I use WatchDog to monitor CPU usage to alert me when ANY processes (system or user-apps) is using more than 40% CPU. Watchdog alert me that these 2 CPU is using MORE than 40% of CPU every 5 seconds, especially when the device is on sleep.
- suspend --> average 48% cpu time
- events/0 --> average 46% cpu time
NOTE: The average above was done over the span of 4 hours
What is "events/0"? More over, why would these 2 processes use almost 50% of my CPU time every 5 seconds?
If the above process using 50% of CPU is "NORMAL", what would cause the lagginess? Do you guys experience these also?
2-3 seconds seems extensive. I have never used Watchdog - perhaps it is causing the lagginess if it is checking processes aggressively.
Could be ROM/Kernel combination also as well as governor settings. Perhaps change your governor to performance and see if that gets rid of the problem (will drain your battery quicker) or ondemand. If problem persists try a different ROM/Kernel combination - some are laggier than others depending on your phone.

Watchdog is a CPU monitoring process application and the reason I installed it is because the lag issue before I install Watchdog.
I use stock ROM, so I don't have governor app in it.
Very unusual for stock ROM to be that laggy. What other applications have you installed recently? Would try to uninstall them and see if lagginess disappears.

@lanwarrior:
Whatever is happening is a direct result of something that you have done/installed/setup..
I have stock rom/root and my results are that in test cases #1 & #3 above where you see 2-3 secs, i see ~0.1-0.2secs
I assume you are setting up constant test conditions, ie
task manager>active>close active apps
task manager>ram>clear memory
settings>apps>running services>stopping all non critical services

I do use ZDBox, an app that close active apps when the screen is off.
I haven't install anything that results in significant system changes. As a matter of fact, I create a list of apps that run in the background so I know what they are.
It seems that many of you don't have that problem, so I'll go back and start uninstalling unnecessary apps and see what happen.
Hi,
Brand new One and HTC user and loving it! I've been trying out the power saver function to help a charge last longer (which I would say so far definitely helps). When it says "conserve CPU usage" has anyone been able to monitor the clock or core activity with this turned on? I'd be interested to see what the trade off actually is...
Sorry I don't know how to access this info yet.
When "Power Saver" is enabled, benchmark apps (like Quadrant Standard) would report the CPU as running at 1134 MHz with 4 cores. Disable power saver & CPU returns to 1728 MHz.

Ah ok, that makes sense then given that I don't notice a huge drop in performance unless I ask it to do something serious. But the battery savings are awesome.
Thanks very much!
Hi guys,
I have noticed on my one that the first CPU core always sits active about 1/3 usage in idle.
If I touch the screen the 4th core becomes active but not 2 or 3.
If this was a single core phone the phone would go flat quickly with constant CPU use, is it an issue with the one and it's 4 cores?
I do not know what is using the CPU time but I would like to get it to use as least amount of CPU where possible, phone never lasts a day.
This is measured in System Panel and Usemon.
I'm on 1.29.980.2 and not rooted.
Cheers
102 views and no comments or suggestions?
No one checked their own Phone to see if it is normal for one core to be very active all the time?
I don't have a second or third One to check if it is normal behaviour.
If I am doing nothing, not running any app or the such the CPU should be minimal CPU use, just idle time..
Thanks
it is absolutely normal that one core is always active with around 30% of usage. if you start to scroll, the device needs a second core, the 4th one, but these two cores have enough power if you're only scrolling. there is no need for the cores 2 & 3, so they are "inactive" to save battery life.
this is absolutely normal
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
EDIT 2: I made a backup for my phone's data through TWRP (Recovery) and then factory reset through TWRP (as my phone's factory reset button in the settings was not functioning). All was good as soon as it booted, took awhile, but it booted. I then restored the backup and bam. The problem was solved. It may have been a problem with the system, but the Logs had shown nothing and nothing would report the mass amount of CPU usage. So a simple factory reset was all I needed.
I'm not sure what I did to make my phone mad.
I'm currently Rooted and S-ON. I'm using ElementalX as my custom kernal and the OS is stock. It started happening when I received my phone back from a repair store as my charge port was short-circuited (overloaded the port). The System would respond incredibly slowly and die quickly (100% to 85% in less then 15 minutes). I went into CPU-Z and noticed that my CPU was at a constant 100% Usage running at 384 MHz. Now, my device runs at a constant 60%-100% at 2.04 GHz (Overclocked by 200 MHz). It does throttle between 1-2 GHz but never goes below 1 GHz for more than 3 seconds.
I checked every app I could and every app reported 100% CPU usage but that NO APP was recorded using CPU above 3% AT ALL.
A thing to note is that in order to (guessing) replace the charge port, they had to remove the bottom speaker. In this case, they destroyed the bottom speaker which does not work anymore. It only makes a *CLICK* sound every half-second. What's weird is that CPU usage increases by 30-50% when the device tries playing sound through the speakers. I'm pretty sure CPU usage increases when playing music to the speakers but not by that much? Anyway, I want to keep resetting the device as a last resort since I need to backup my photos and videos but I can't since the CPU is being hogged and can not turn on MTP.
Please help me!
EDIT 1: A quick check at CatLog makes me certain that the device is unable to "read mount points" when connected to a USB port. Any ideas?
did you check your govenor setting? make sure it is "ondemand" or something else, not "performance"

I tried putting it on Performance thinking that the extra juice will keep up but alas it completely froze my device, in some cases crashing it and causing it to restart. It is set to OnDemand right now.

performance is just for bench marking, not good for daily use. Ondemand will raises your clock speed in heavy task, and lower it when not needed to save battery
You're talking to a tech geek too. Anyway, any ideas on how to find out what's using all that CPU?
I've given up.. I'm going to just back up the Data through TWRP and restore it later. Please delete/lock this thread.
