x10 uses ondemand cpu scaling 245 - 998 mhz stock, do not use setcpu

just wanted to let everyone know this, as there are still plenty of threads out there that suggest setcpu, and it's a waste of time

Thanks dan, where you been stranger?

so what does it mean? it's doing what setcpu does? what about battery and temperature profiles? what if i want to force the cpu to use a lower clock speed to conserve battery?

I never understood SetCPU myself. The CPU is only used when required, so creating all these settings likely does nothing.
I'd consider it for overclocking, if that was possible.

I was also informed that our phones should do this anyway but I was suspicious of how well it does, being on 1.6 and butchered by SE after all.. it made a good deal of difference before the update.
Trying it without the update now and we'll see how it goes. Completely removed it and power cycled. Will bump in a few days with my results.

I found android got extremely laggy on 1.6 with setcpu. and I use a temp/cpu widget to keep tabs on stock behavior, my cpu sits at 245 most of the time, except when I'm using the phone

What widget do you use?
I took a quick look on the Market and AppBrain, and couldn't find anything to track/plot CPU clock to see what the phone's doing while in standby.
I do use SystemPanel, but it doesn't plot CPU clock over time, only usage.

Try advanced task manager it shows cpu speed...

I'm not looking for a way to see the speed. SystemPanel will do that. I'm looking for a plot that shows the cpu speed over time, so I can see how and when it changes.

Try Usage Timelines Free or seepu++ (not free and dev seems to have abandoned it)
Edit: sorry I see you want clock speed not usage. I have yet to find an app for that as well.

so what is SetCPU doing then? draining the battery? or is it affecting the charging process?
and what about the app CoolS? its almost the same thing as SetCPU but the only thing you can do is slow the CPU down

You can use SetCPU to:
1. Overclock (but not on X10)
2. Underclock (you know you go somewhere for 2 days and forgot the charger at home)
3. Make profiles to lower CPU freq when temp is too high
For day by day use, i'm ok with android's ondemand scaling.

use android hackers apk. thereu can see theCPU over time...

i use setcpu to underclock my X10 to 5xx mhz when the screen is off.
my batt usage is better, from 3-5% per hour to below 2%.

I've been using overclock widget to keep it to 998mhz to see if it would make a difference in quadrant. Recently i uninstalled it and i still get about the same benchmark score.

What is the processor temp safe range?

(Title)
I ask because I used SetCPU to overclock in CM7 to 787 (806 locks my phone up), and I want to be sure the temp stays okay.

i'm not sure about an actual temperature range, but i would say anything that doesn't burn your hand when you hold it is acceptable. what build of cm7 are you using? i've been running set cpu set at 806 with nightly builds from a week ago up to today (13-19) with no issues.

Running build 18. 806 has always locked my phone up, even on CM6

But afaik, the temp the phone gives you is the battery temp, not the cpu temp, so it could be much higher than the reported number...
Anyway, 42° is moreless the line temp for me.

Huh. Didn't know that. Thanks for the info.
My battery got to around 46C while charging.

Well, if it's just charging you can create a setcpu profile that it lowers the mhz when doing so, so it doesnt heat up too much. At any rate, supposedly every good device should work fine under 50°C, if it's charging without overclock and you still get 46° then it should be safe.

If you can't measure it, you can't manage it. Try loading the "Perfect System Monitor" app from the Market. It will give you CPU temp data. I wouldn't worry about anything under ~50* C.

[Q] is there a cpu temp monitor?

I have Setcpu for it's widget, but it always displays the CPU temp at 32 degrees Fahrenheit, no matter how hard I run it. Does the Nook even have a CPU thermometer?

Couple of choices: Temp+CPU Pro
and
TempMonitor
Never felt the need to monitor processor temperature myself but heck. Take a look.

Temp monitor tells you the battery temp, not the CPU temp.....unless a modded Droid 1....

Yea I kinda thought there wasn't a CPU temp reader

Real CPU temp

Hi everyone,
Today my S4 gets overheated so I installed app to control CPU temp, but can someone tell me what is a real CPU temp? Coz two apps shows me different values.
CPUTemp is on overlay and Cool Master is on main window. What app shows real temp? And my CPU temp is ok? Coz I wasnt using any heavy app when getting screenshot, its normal state.
Sent from my GT-I9505 using XDA Free mobile app

I have bigger difference using same apps.
on standby cputemp app shows ~30. Simple browsing - 40. Candycrush gaming or intensive browsing - 50-60 degrees.
Cool master shows almost -30 degrees too. Don't know if any of them shows correct temperature. I believe cputemp results are more accurate

Mi 9T Incorrect CPU Temperature Readings

Hi there, so I recently received the Mi 9T I just bought a few weeks ago, and the first I noticed is that the phone is perfectly fine except for one thing: CPU Temperature. I set up the phone usually as how I set up my phones, and since I had a history of overheating phones, a good CPU Temp monitoring app is a must.
So I installed CPU/GPU Meter & Notification, but to my surprise, the CPU Temp is stuck at 37°C regardless of how hot or cold the phone is. (Even put it in a fridge for 15 minutes just to test it out). I also installed other CPU Monitoring apps but all have a static reading. However, using AIDA64 and CPU-Z has some readings on various temp sensors on the phone, though I'd note that the pm6150-tz displays a steady 37°C, which is most likely, the CPU Temp. Since the other readings there (~cpu specifically) update constantly, it rules out sensor problem.
I thought this might've been a problem with ROM, so I tried flashing Xiaomi.EU ROM, 12.0.3 Stable, and rooted with Magisk, but still, same problem. I went on googling about how to get temps and I came across thermal zone paths right on
(sys/devices/virtual/thermal_zone+zoneNumber/temp) in which had some crazy numbers (when viewed as text), one of them has 37000, 37100, etc. I don't know if this has a part in the problem or what, since this ticks something https://www.reddit.com/r/Mi9T/comments/cwqrqm/cpu_z_pm6150ibat_lv0_and_lv1_very_high_temperature/
I experimented with my phone even further and saw that CPU Monitor app View attachment 5053905 does have some CPU temps that do actually update (not just steady 37°C) when I charge the phone, or do some tasks. Though eventually, it's stuck again on that 42°C, which doesn't seem right at all since if I have 42 degrees, then I should feel the heat on my phone, but in reality, I don't even feel any heat at all, and the phone doesn't seem to be having a 42°C temp.
I ruled out bad heat dissipation as well by prying open the back of the phone and reapplying thermal paste (I used Arctic MX-4 btw). Yeah, forget about the warranty and such.
May I ask if everyone else has this problem? Maybe if you guys have some time to try out these two apps: CPU/GPU Meter & Notification, and CPU Monitor to check if your devices have the same problem or it's only isolated to just my phone.
I'd also like to know if this is not an isolated case, is it possible that there is a software problem? And can be ironed out by future updates?
Thank you!

UPDATE: It seems to have readings with CPU Monitor app (https://play.google.com/store/apps/details?id=com.glgjing.stark&hl=en) but they are quite inaccurate and puzzling. According to the app, when phone is at idle, CPU temperature are at 36-37 degrees, however, as soon as I plug the charger, the CPU temperature rise up to 40 degrees within 2 seconds, then when I unplug the charger abruptly, it goes back to 37 degrees instantly.
I let it charge for a while and did the same thing, only this time, the CPU temperature dropped to 38 degrees (from 41 degrees while the charger is connected), and the phone feels a bit warm, let's say it feels like 38 degrees for real, that's warmth is comparable to the heat of your neck when you have a mild fever

Go to aida64 and find a thermal zone you want to monitor, then find an app that gives you the ability to change the thermal zone to monitor.
I'm curious if changing thermal paste had any effect. Can you start a stress test and monitor cpu-0 and cpu-1 temps and see how soon it throttles?

I don't get it, how can I find an app that does exactly change the thermal zone to monitor, since I've already tried most of them, and they only go after the pm6150-tz sensor. Only CPU-Z and AIDA64 had readings from other sensors.
For the stress tests, I've been conducting tests on 3DMark, and it gets lower scores after the first OpenGL 3.1 Extreme Test completes. I can't switch over to AIDA64 to monitor temps tho, the phone simply lags a lot that I can't even see notifications properly until the stress tests are over.
I would like to try Antutu but I don't want to download it outside of the play store.
Changing thermal paste didnt have any effect for the temp readings. It only made the phone's frame heat a little faster, which I think means I put enough thermal paste that heat dissipation is good

Ok, I don't know of any apps that can do it that way properly. But anyway, I don't think you need to worry about temperatures. Especially if the frame heats up a bit faster now which indicates bettee dissipation. I think it's more important to monitor battery temps anyway.

No closer to finding the solution to any of this, but I can second the crazy-high/static reading behaviour on the Mi 9T. Elixir 2 reports 3700°C as the CPU temp (also only reads 0% usage as well, but that's not necessarily relevant) and CPU Monitor seems to vary, in use, between 35°C and 38°C, but normally sits on 36°C or 37°C.
Currently running: MiUI global 12.04 (stable), but NOT rooted at all.
Again, all other sensors seem to be working fine.

What is the meaning of PM6150-tz ? whats that?

I know this is probably too late now, but the pm6150-tz was actually the Power Management IC which I think is in charge of device charging and/or CPU/ROM power management. The tz means it's the thermal zone (thermal sensor)

This problem is solved by installing AnTuTu Benchmark and enabling CPU temperature monitoring. However, if you wanted to use a different one with more features, try using Scene6 app. (If you dont mind it being a paid app and having still most of the app in Chinese).
