[Q] Tackling Serious Samsung Galaxy S Issue (found with Temp+CPUV2)

Hello guys,
I recently installed an app from the market called Temp+CPUV2. All the app does is it displays CPU Clock speed, CPU Utilization %, CPU Temperature, and Free RAM on a tile as a Widget.
lately, I have been observing fluctuations in the clock which ranges from 100MHz to 1GHz. I thought the widget was faulty. Then later on, I began observing constantly time to time and I found out that the phone really operates on different frequency at different times. Apart from changing the clock speed, I think the self-assessing algorithm eats too much RAM figuring out next clock speed and slows down the phone.
I assume that this features is implemented to save battery, but at the same time, this feature kills the phone by slowing it down so badly that I sometimes feel like smashing the phone against a wall or something.
I use a rooted JM1 with SU and no other mods.
Is there any way to stop the phone from assessing the clock and change it from time to time? I think that's the real reason why the phone lags in he first place.

Nope, thats just the way it works. Install a overclocking kernel and SetCPU if you want to control the clock speed but I advise you just uninstall that widget and not bother worrying about it as you are getting worked up over nothing. SetCPU and a kernel is more trouble then its worth and is very unstable

That's a powersave mechanic.
Save your battery.
It also try to keep your phone cold.
In fact it work well.
It same in computers.

I doubt the lag you are getting has anything to do with this. Look for the lag fixes like Voodoo, Z4mod, or OCLF.
I use z4mod myself, flawless performance

[Q] CPU throttling on Revolution

Long time lurker, but 1st time poster.
I've noticed on my Revolution that the CPU always runs at 1ghz. I thought CPU throttling was a standard feature in android?
Anyhow I installed CPU tuner and I get much better standby battery life now (~2% drain/hr when not using phone vs. ~5% drain/hr on standby). The phone runs mostly at 124mhz w the screen off. My problem is my revolution reboots pretty frequently and sometimes even just completely shuts down w CPU tuner on. I still get reboots once in awhile w CPU tuner turned off, but much less frequently.
Anyone else having this problem? I also have green power running in the background to turn off the data connection w the screen off. Are you guys who use setCPU not getting reboots? If so I'll spend the $2 and give that a try.

I honestly don't think anyone has been messing with the CPU until the CM ROM is released.

As far as I've seen, the Revo's CPU does automatically speed scale to the necessary load.
If you're running lots of apps in the background, with the screen on Android will keep the cpu at full throttle to provide a smooth experience for you.
As soon as you turn off the screen, it will throttle it down as much as it can.
If the phone's rebooting on you, that's because whatever cpu tuner is doing may be keeping the cpu speed too low for the demand of the OS, then the watchdog kicks in when it thinks the cpu is stuck in a loop. (watchdog wants to be petted every 30 seconds, if the cpu misses that, the watchdog reboots the phone)

I use setcpu and have no reboot issues.

throttle
I use android system info to show the CPU speed. It shows the % of time my revolution is running at each speed. W/o using a 3rd party app it always shows 100% at 1Ghz. W CPU tuner running it shows 50% at 122Mhz, 25% at 1Ghz, and 25% in between.
I don't think I'm running any apps thats sucking up a lot of CPU. I'm rooted w most of bloat removed.
Am I the only one not seeing any CPU throttle on stock?

i'm not seeing any throttling on stock.
setcpu drastically improved battery life when the phone's off, and no reboot issues.
some issues initially with the phone not throttling back up quickly enough when i got a call, making me unable to answer the call, but played with the settings and made it so it automatically throttles back up to 1024 when i get a call, and now it's fine.

Exactly Im much happier with my phone now. I had the same issue when I received a call but set up the profile as u did and have no problems at all

I am using setCPU as well with no issues. I have mine set were the screen is off it goes to 124 and clocks back up to full 1GHz when it is on. Helps greatly improve my battery.

So what settings do you use? I get really bad lag when waking my Revo. Sometimes it will reboot after waking too.

I don't know if this is a CPU throttling issue, or a general REVO issue, but I get horrible horrible lag sometimes trying to get any programs to respond. Like press the home key, or click send, or anything like that. I'm running Decrap 1.1, I don't know if I have too many processes running or what.

Interesting. The Thunderbolt has the same issue. Is it the same CPU in that phone?

Thermal Settings

I have noticed the Xiaomi Mix has some persistent software thermal throttling after a short period of time.
I ran the same test on a OnePlus 3T and noticed this throttling issue is not present.
It's possible the temps to start throttling are too low on the Mix.
Is there any way to modify or increase these throttle limits?
I know this has been done before but I cannot load the Thermal conf file in /system/ etc / thermal-engine.conf
Can we replace the file with something else ?
The OnePlus forum members released several versions of the file with different throttling temps. Can we use these files or make our own.

Did you ever get any further with this? My phone idles at ~35C. I read a review that said throttling begins at ~40C so I get throttled when I do virtually anything.
I've only had this thing 2 days and the performance has been worse than my old Nexus 6 because the cores keep getting capped very low. I was copying some backed up files over WiFi from my PC. It was lots of small files so it was running for 20 mins or so. When I was trying to do other stuff in the meantime it started to get really sluggish. I used to do exactly the same thing on my N6 and I could never tell that file copying was running in the background. I checked Kernel Auditor and it was showing temps ~50C and the cores were all being capped around 5-600MHz.
I've tried the stock ROM (stable and beta) and EPIC, and Lineage/RR. It seems to be a bit worse on the latter two (Antutu won't go above 100k, but it's like 140k on the MIUI ones) for some reason, but it's an issue on all of them.

I have absolutely gotten further here I have managed to get throttling completely disabled actually.
The highest temp the CPU got to was 42 degrees Celsius after running Dolphin for 2 hours straight.
There is no need for thermal throttling on this device at all, hardware does a good enough job clearing the heat.
To stop the thermal throttling you need root access.
Use ES File Explorer from the play store and enable root access
Navigate to root and look for Folder system/etc and find file called thermal*******.*** ( I don't remember what it's called )
Cut this file from this location and paste it into another directory. I moved it to the sdcard for easy access. This way you can move it back if you do not like the results.
I have not experienced any overheating with this, also the battery doesn't drain like crazy. Performance is greatly improved with speed matching the Snapdragon 835 in a few scenarios.
Oh yeah restart the phone after you move the file so it can register the changes. Clock the cores appropriately with Kernal Auditor to make sure it can run at full blast when it needs to. On demand is way faster than interactive.

Cheers. I actually read the links you posted and renamed the conf file. After a reboot it was flying. The problem isn't so much the throttling, it's that mine idles at ~35C already, so it was getting capped when I did virtually anything. If I run Antutu 2-3 times in a row and check the temps in Kernel Auditor it can be in the low 60s. Using other temp apps (CPUTemp) it only shows about 45C tops.
It definitely does feel pretty damn warm since I don't use a case. but I'd love to know what the 'real' temp was. I tend to believe the lower one since I got the 45C warning when using EPIC and that's exactly what the app said. it was.
My Antutu scores increased substantially too. I was sometimes dipping down to 80-90k but I regularly get ~140k now, even 160k once. I know not to go by those scores but when I could never even get above 100k it was a concern.

Yeah I'm thinking Xiaomi severely limits the thermal threshold to improve battery performance.
It's kinda all they care about in Japan for some reason.
Makes for some great performance improvements without the thermal settings being active.
This setting change is almost necessary of you need some heavy work done.
Glad you were able to get this changed.

i remove thermal_8896_blabla.conf...
Honestly device become too hot for me.... backplate change during my game (Battle Bay), very different sensation... reinstall immediatly *.conf... Finally i have decent perf and cold phone and very good battery life... no more...
My opinion !

I think our best solution would be a modified .conf file that increases the thermal threshold as opposed to completely removing it.
Until this solution is available then this is our only choice.

i agree... i think with a ROM kitchen mayve this fil can be readable... anyway @ this point, we can only hope somebody dectypt this file to support various cool modification available over XDA...
Edit /
it seems HTC make same stuff... here it is a guideline ot example...

I had the same issue. I was getting 165k+ in Antutu but the phone would get uncomfortably warm when doing multiple passes, or gaming for extended periods.
In the Thermal section of Kernel Auditor, I enabled the Core Control and Temperature Throttle options and the phone still gets warm, but only as warm as you'd expect. I still get ~155k in Antutu consistently and the performance in general is still very smooth. I have the CPU governor set to ondemand, and the GPU governor to simple_ondemand. All other KA settings are default.
One other thing I always do is to reduce the Window Animation, Transition Animation and Animator duration scales to .5x (1x by default). It just makes the phone feel snappier in general. Settings > Additional settings > Developer options (MIUI-based).
I'm using the latest EPIC ROM. Using RR/LOS I couldn't replicate the same high Antutu scores consistently for some reason. I quite like MIUI after years of using CM and CM-like ROMS anyway.

already reduce animation x0.5... MIUI use a lot of this animation with complex and (very long calcul) then reduce this number make device seems much faster... anyway, u right...
A custom kernel for miui base... based on Dragon XIA exist in MI5 thread... only need to play a bit to make universal... with all source we can make somthing, but no have time to play with all tutorial available on XDA or Youtube...
Only way to make device much smoother and battery friendly or Perf/Warm destructor...

New galaxy note 4 prevent emmc issue

Is there anything I can do on a new galaxy note 4 to prevent the emmc issue happening in the first place?

There was some talk about preventing overheating?

It might help to lower the CPU speed, but you need access to root and an app to tweak the values.
Avoid gaming which is very demanding on GPU and avoid gaming for long periods of time.
Search also in the Snapdragon forum a good kernel.
Also turn off the fast charging, this can heat too much the phone.

I created a script here. It works very good, it monitors the battery temperature AND all the CPU cores temperatures, and will automatically throttle the phone if temps are too high. You can even kill some apps if the temps are to high (not yet implemented).
The difference with Samsung DVFS or integrated temperature management of kernels is that this one monitors almost all CPU sensors and also the battery, all in complete combination, and it can be easily tweaked (rather than modding a kernel). No battery hog. You can enable USB fast charge, game, etc it will still prevent overheating.
Here is the solution to eMMC error
Hello everyone, I was pretty tired of the eMMC error, and I created a script that completely annihilate this error. This error is due to the phone heating up, and the fact that custom kernels (maybe even the original kernel) don't read the...

Not removing thermal throttle, but increasing thereshold? (PerfZ bug)

A month ago or so, i had this random period of time where perfZ started to show "-" for temperature ( i assume its gpu temperature because it doesnt match with battery or cpu temp from another app) and my phone was heating up much more in games but so was the performance was way better.
Normally after thermal throttling kicks in and device reaches heat equilibrium, my battery would sit around 38-39C, cpu at 42-43C. But in that time period where it showed "-", my equilibrium was battery sitting at 44C, cpu at 47-48C. Phone was considerably hotter to touch but you could still game on it. And performance was way better, it would fall to 50fps min instead of 40fps, which is very noticable. (Dont have exact numbers maybe a bit better)
Idk how this happened as it randomly happened one day but does anyone know how to make this work? My device isnt rooted. (s10+ exy)
(Small note: Using game plugins at max performance or custom doesnt help, maybe they arent optimised for dead by daylight, because thats the only game i play)
