hey guys, just wondering will using a lower vsel damage my cpu and/or battery?
i have previously beein using milestone overclock on 1ghz and 60 vsel and am adding setvsel into the mix, also any ideas on starter settings? thanks
also could someone just give me a heads up on what vsel actually IS
I don't believe there are any studies that show effects of long term use of lowering the voltage, which is what you are doing with vsel in order to save battery juice...or you could increase the voltage but that defeats the purpose and also heats up the battery which leads to shorter life span. Many use it without reporting any damage to battery or cpu, I believe it's safe (however, if you are overheating you might fry the battery or cpu, so you'll need to moniter and play with settings to get the desired effect without any overheating issues).
With regards to setvsel, there are reported issues from users with different roms...from what I've read (and you can do your own research to see if this is what you are seeing...this is the conclusion that I've come to by reading a lot of threads), it is better to use milestone to overclock and setcpu to lower the vsel.
With that being said, I've used them all and like setvsel so keep going back to it...but I've been having some issues lately so I've removed setvsel to see if that is what is causing some problems (too early to tell).
Oh, and as for settings...pop on the overclocking/undervolting thread in the development section to see a lot of different settings and remember that what works for one user might not work for you...you'll have to experiment a bit to find your ideal setting.
oh okay i think i might go back to my old settings with milestone overclock and setcpu and just lower the vsel! i was under the impression for some reason that lowering the vsel would heat the battery. Thanks!
I'm no expert to be honest, I'm more of a research kinda person. From what I've researched, undervolting can help keep temps down, and may particularly help when you overclock (as overclocking is stressing the cpu to go beyond it's normal operating design hence it may heat up...supplying it with less power, or voltage, is what helps keep the temps down.
Of course, this is given you find the optimal setting for your phone, and as it seems from reading through these forums, many users have experienced completely different results using the same settings (i.e., one user will have a stable setting without any problems while another user on the same rom using the same settings will have crashes and/or issues like overheating). Doesn't seem right, but it is what it is
yeah ive read through most of that stuff too, i went down to 1ghz at 51 vsel, seeming stable, but i decided to go with 54 anyway
1.1 GHz @ Stock vsel for over a month without any issues...I hope it lasts.

Hi,
I've also read a lot regarding the underclocking 'dangers' but couldn't find anything to prove that there is such an issue. I think that it is an urban myth spread everywhere by people asking if there is a danger with low vsel [but that are never getting a positive answer on it].
The only thing I found using setvSel is that I had to first install Milestone Overclock and load its module prior to start setvsel. There is a way around it, but requires you to copy files in the system folders and change their permissions. I find that my way is much easier.
As far as over-heating goes, it's an overclocking thing; not underclocking.
My Defy is set at 900Mhz and really, I don't see the point of going much higher: everything runs smooth and lag free already.
vsel: 21/300; 32/600; 43/900 - 90% up_threshold
Been like that for about a month now and never experienced any problem at all.
The underclocking is great for saving battery; no exact numbers to give here but it feels like my battery now last 2 times longer. I can easily get 4 days between charges with low/moderate usage and would get to 6+ days "IF" I could stay away from games and having the screen ON for long sessions of browsing/video watching.
I tried SetCpu before but I didn't like the interface; the simplicity of SetvSel is really nice.
i use setcpu for scaling and profiles, and run 18/300, 36/600, 50/1000 stable and smooth as
Undervolting is not a bad thing at all. It means less Watts consumed for running (Watts = Voltage x Amperage), less of your battery consumed.
Ussually companies test a large batch of components and how they react on different voltages and freqvencies, and then they decide for a voltage that works with all components and that is safe for all cases. Eg. when they have different CPU speeds and thus different options for CPU's this is one way to decide which one work at 3GHz and which one at 2.7 GHz (the other one is demand for components).
Phisically you will not have any problems and you can't damage your phone by undervolting, so no problem here, only possible software problems if you go too low.
Advantages :
+ Lower processor temperature
+ Lower phone temperature
+ Longer battery time
+ Longer components life
Disadvantages
- Stability issues (freeze, artefacts, slowness)

You know, I was recording a video and when playing back noticed that there were squiggly lines that went through the video a couple of times (in a two minute clip). This was the first time I saw this...and have recently lowered vsel by 2 on vsel3...could that be the artifacts that you are mentioning?
I just figured it perhaps I was too bouncy with the phone while recording making it glitch...but now that I see this post I'm thinking maybe I undervolted too much...what do you think?
My settings: 54/1000 44/700 28/300
I know what people mean by same settings don't work for every phone even if it's the exact same model. My Defy won't underclock as much as others. I'm using SetVesel, and I've been able to drop 5 points from each, and that's about it before it reboots itself. I only tested undervolting, but I mainly overclock to get as much speed as I can, and give it enough juice to run super fast. I'm current running [email protected], [email protected], [email protected] Threshold at 75%. The highest the temp ever got was 112F, and that was after playing a game for about an hour. Usually it stays below 90F for normal use. I get around 17-20 hours out of it with screen on time at about 3 hours @ 50% brightness. I've been running these settings about a month, and have not had any issues.
If you put something like 100vsel will the phone accept and then burn? Is there any protection? Does anyone know what's the highest acceptable vsel?
Just for curiosity...
im pretty sure 80 is the highest you should EVER use and that'll significantly increase the chances of your phone burning out. @bobbyphoenix you should be able to lower your vsels a fair bit or your really unlucky! i run a lower vsel for 1ghz than u do for 700mhz smooth and stable

CM7, rather non-technical person here. I seem to have a very happy phone at setvsel settings of [email protected], [email protected], [email protected], 86%. Been running this for the month or so since I rooted and the phone feels like it was made for this config. I've never seen the temp above ~32c. My 2¢.
My average CPU temp is 34°C (93°F), and I go up to 67°C (152°F) when I play games (like GTA-VC).
Do you think it's normal that kind of temperature from the S4Pro ?
Actually this is really low...
67c on high load like games, which stress the cpu?
My device goes to 80c easily, starts to throttle cpu speed and shut down cores, all of the devices do that. This temps are normal.
By the way which app you used to measure that temps?
If you really want to see how your device holding up,
Download that app:
https://play.google.com/store/apps/details?id=com.into.stability
While run the classic Stability Test measure your cpu usage and temps.
Personally I use FauxClock.
After a few minutes you'll see the high temps and the cores throttle.
Oh, joining this question. Just got a 32Gb LTE version and found out it's getting quite warm when playing something like Osmos, Doodle Jump or something. I don't know how to get the exact temperature, cause monitors I' found on market, show only the battery temp. Anyway who else gets his N7 warm/hot when some heavy app is running? Asking, cause my friend also got the same N7 and I don't remember it to be hot even after running 3D games for quite a long time.
I used the app "System Tuner" from gplay.
Apparently, your StabilityTest app requires more power than GTA-VC, I recorded a 82°C with a 50mV undervolt (on Franco r3 kernel) after a 8min StabilityTest, then I just stopped it. I'm a little afraid of this kind of temperature :/ Are you sure it's okay ? I don't know well the mobile device world...
That's the real temperature , even higher,
And you don't need to worry too much.
Your device will turn off if the CPU reaches too high CPU temp,
And 80-90 c is fine. The soc is built to work on that temps.
As you could see your CPU shutdown cores and lower cores speed while the temperatures going higher, that's called throttle.
You don't need to worry too much.

StabilityTest can load all 4 CPU cores 100%. You won't find a game that does that.
The CPU will be thermally throttled (clock frequency will be limited when the temperature is too high), so you won't damage anything.
And is the average temp of 45-50 °C normal? I'm just using Skype and surfing the internet.

If you run a adb logcat while gaming you start to see alerts going off for high temperatures when it gets around 70°c or higher. I found it very interesting that it was alerting when it got that high instead of ignoring it like you say till 80-90°c.

Games use GPU which adds much more heat to the conclusion.
Stability Test don't.

The device doesn't ignore it till 80-90c. It's start at 60c.
I just say that it's safe temp for the soc to operate. Which means your cpu never use all cores, and the cores that active wouldn't be at the highest speed, while the cpu reaches 60c, more heat more throttle.
Ok thanks to all of you, so it's like computers : if it's too hot, it will stop before it reaches a dangerous temperature.

Those are quite ok. If you include skype with voice/video calling ofcourse. I just get about 30-40 with just surfing and chatting facebook messenger skype/yahoo/viber on background
I'm fairly sure the CPU tends to downclock itself not because IT is getting too hot, but because it's generating too much heat for the battery. Almost all CPUs can easily withstand upwards of 80C. Batteries, on the other hand, can't.
I am trying to figure out if my temps are normal or not.
My T700 is on the latest 5.0.1.
While its idle the temps are around 40c-50c.
However when the proc is being used even ever so slightly it will spike to 60c-75c.
I decided to run some tests like AnTuTu and when it gets to the CPU part of the tests it spikes as high as 80c-90c
Is this normal? I tried to do this to one at the store and the results were still around 80c.
Im trying to decide between the T230 and the T700 for my daugher.
She mainly uses it for educational games and movies etc.
That device wont break 40C even when running AnTuTu.
Please post your results and any insight you might have.
Thanks!
spiking to 60-75c is normal 90c is a a bit too hot, but if it`s only at 90c for a few seconds that is not a problem, if you can find an app that can do a graph of the temperature while running AnTuTu and see how long it stays at 90c
I have been trying to find the maximum temps for arm cpu`s but i cannot find anything, but on another android forum they recommended keeping the temp under 80c

my tab s does the same thing I wouldn't worry about it.
What are the normal temperature for oneplus 3, when playing games, using fb,messsenger,whatsapp in 4g and watching video and doing all the same activities in an ambent temperature of 29
I don't think many people actually measure temps of their phones ... Suffice to say - it can get pretty warm, but not too hot (maybe max around 45°C on surface). Internal (cpu) I guess could easily achieve 70+.
P.S.: Stop being so paranoid! This is at least third thread you opened about temperatures and people keep telling you that your phone is NOT overheating ...

This is the reason
I posted a pic using cpu Z... It was when I was uploading a video in Instagram.... See sensors Reaching 50-55???
I was tethering and using Instagram.. Is this normal for this
With light usage i get about 30°c and on heavy load the cpu goes up to 70°c, those temps are pretty normal
FFS it's a metal backed device which conducts heat but also passively cools faster. Devices are getting very powerful. I came from a Z3+ which hit 80-90 °c on the soc. This device is no where near being "hot" and that's from running consistent synthetic benchmarks and gets to 50°c but cooled very fast.
If it hits 80°c + on the Soc not the individual cores as they ramp up and down very fast then maybe you can repost.
Holy crap I'm tired of this... Those sensors are for the CPU, the CPU throttles at 85°C and here you are asking us the same question in which we've already answered you.. THERE IS NO PROBLEM with your phone. Now stop asking these questions and stop being so freakin paranoid. It's hot outside your phone will get hot.
Attached below is a picture of my Hardware activity while playing Power Rangers Legacy Wars which admittedly is a graphically intense games but I'm worried that the temperature of the GPU and or CPU is getting too high. I want to make sure my Note 4 isn't getting too hot here is the picture:
I need somebody's help. The coolest my Note 4 seems to get is about 53 degrees C and that's when I turn it on after it's been asleep on my desk. It is not a rogue app or anything like that because I have done both Factory resets and I have install custom roms, so everything has been factory reset multiple times. The water damage sticker indicates no water damage whatsoever. I know phones can get hot when gaming, my Note 4 gets to anywhere between 70 to 85 degrees Celsius and I am just wondering if that's normal I reduced my screen resolution to 720P and disabled two cores of the quad core processor and it does not seem to help one bit. Is this temperature normal or do I need to get rid of the phone?
PS when doing normal browsing it seems to hover around 60 to 67 degrees C
And the battery does not seem to go over 37 degrees Celsius
If you're worried about high temps during games I'd recommend turning the max GPU frequency down. It significantly reduced my temps and I didn't notice a significant difference in gameplay.
Thank you for your response. I have done that and it does not seem to make a difference I'm still getting CPU and GPU temperatures in the high 70s to low 80s

Would you mind posting a screenshot as above with the same overlay? How long are you playing before it gets to this point? Have you adjusted throttling temperatures?
Edit: Saw your other post and wanted to add some troubleshooting. When you open up TWRP and do a file transfer or backup how hot does your phone get? Mine would get pretty hot to the touch, but I don't remember it getting above 80 C.....
The temps you showed in the other thread are definitely not "normal" from my experience with day-to-day use. Did you ever look at the task monitor app I linked to?
Sure I can take another screenshot. How do you want it? I did check out that app and the only thing that I saw was that it seems as though my CPU cores were always running pretty high but I didn't see any applications taking up and unusual amount of processing power. The temperature ranges to about 60 as soon as I open a game for the most part and continues to slowly rise from there. Yes that's about the temperature I get everytime I go into TWRP. I don't even have to be doing anything I'm just open TWRP work and that's about the temperature I get

Sorry, I posted that before I noticed your updated screenshot. I was just curious if limiting the GPU made any difference.
Honestly I'm running out of software suggestions. Do you have some sort of case/screen protector that could be affecting it? How hot us your screen (qualitatively)? I just looked at an old video I made and my phone was 52 C in TWRP, which isn't too far off from yours so it might be fine (as I said my phone screen would get too hot to touch at times during intense games). But if you look at kernel adiutor and see that the CPU rarely drops to the lowest frequency/deep sleep there's probably something wrong (unless your screen is constantly on). You could try a different kernel or governor, or check an app like gsm battery monitor to see if GPS or something us hogging CPU time, but I don't really have any more ideas. (Although I did used to cool off my screen with a wet towel when it got really hot)
Just to confirm: you're running a Verizon note 4 right? (Have to ask)
You've updated the modem to the correct version through Odin?
You're on the proper bootloader?
First of all thank you for your help once again. I don't know how to measure how hot my screen gets I don't have any tools that would allow me to do that I do have a case and screen protector on but it doesn't seem to be any worse than it was before I put them on. Yes I am on the correct bootloader and I do have a Verizon Note 4 running the nseven ROM and I am on the correct modem. I'm willing to do anything at this point. This is the second note 4 I've had with this issue and I just want to be able to use it. I want to be able to play my games and stuff you know. So if there's a literally anything I can do . plus I don't really have money for a replacement

I found this: https://forums.androidcentral.com/s...bout-cpu-temperatures-according-cpu-z-s6.html
Which shows some pretty high temperatures during heavy and normal loads for a G4 and some other forum discussing how their note 4 would reboot due to overheating. Since you're not experiencing that issue I'm not sure you need to worry too much. Your processor should be throttling itself if it's getting to hot to make sure it doesn't get damaged. I'd try to make sure that you limit your gpu to around 300 and then just make sure your CPU isn't overclocked and you will probably be fine. My note 4 would get so hot that I couldn't touch the screen, but it still ran like a champ and never rebooted on me. The only thing that is concerning is that your CPU clock specs aren't sticking, but you'll need to read around for how to fix that since I've never had an issue.
Okay well that makes me feel a whole lot better thank you. According to GSMArena the processor speed of the Note 4 is 2.7 gigahertz and mine is currently running at 2.4 so while it is a little upsetting that I can't bring it down any further, at least I know again according to GSMArena that my processor is not overclocked. Thank you for everything
