Hey guys, in franco's kernel thread I already said that I wanna test the lowest possible voltages for each frequency for me. Now it seems that I have some stable values and I want to test if it's worth to undervolt. For now I want to see what impact that low voltages have in terms of overheat. Therefore I need some 'testers' who download the following app:
https://play.google.com/store/apps/details?id=com.into.stability&hl=de
What I want you to do is to run the CPU/GPU test at full details with your NOT UNDERVOLTED HTC One X and provide me your current temperatur (you will see it in the upper right korner) after 20 CPU passes.
Relevant would be which ROM and which kernel you are using. It's also important that you don't do the test after a 2 hour game session cause that would distort the results of course.
Here are my results with my undervolted One X:
ROM: maXimus V2.0
Kernel: Franco r11 undervolted
Temperature after 20 CPU passes: 39.6°C
StabilityTest-CPU/GPUTest
ROM: Stock rom 1.29.401.11
Temperature after 20 CPU passes: 48.5°C
I must say I just recovered so my phone did a lot of work.
The back of the phone is just warm after the test, nothing to panic.

Thank you for testing, if all One X with stock rom get that much warmer, stock voltages are way too high. Maybe it's just a result of recovery as you said, waiting for another tester

This test won't be very meaningful, unless you also consider ambient (room) temperature, whether the phone is in shade or direct sunlight, what the screen brightness level is, what the starting temperature is, and most importantly whether there's a case on the phone (or even that it's being held, versus placed on a desk).
Even then, there will still be minor differences from things like which radios are turned on, perhaps how many background services are active, even the color of the phone might well make some small difference. (Grey will radiate heat out better than black in a cool, shady place, but will collect ambient heat that the white would reflect under direct sunlight.)
With that said, thanks for the effort. Anything's better than nothing, just figured I'd share some thoughts on how the procedure could be improved to provide better data...

Of course you are completely right. I thought this too but kinda trusted the testers so they won't holt it straight in the sunlight or place it on a heating or in a fridge.. As you said there are also some factors like screen brighness, casing or room temperature so this test has obviously no scientific relevance. Anyway I think those tests will give me a hint if the undervolting makes sense. I will just be looking at the average of the users who are posting their results (thanks again for you help guys) and assume that the values will approach to an average room temperatur, average screen brightness, average device placement etc. so that the extremes got ironed out. Therefore it's beneficial that I have alot of testers so I can look on a wider base.

I've been playing around with TegraStats for a while now and found out, that the CPU's up- and downscaling acts kinda weird from time to time.
For example, running CPU intensive tasks like Antutu benchmark will fire up all four cores, but maximum clock was always 1200 MHz instead of 1400 MHz. Seems kinda "capped" through kernel parameters (correct me if I'm wrong).
So I've tried Shadowgun after benchmarking. In this case, the CPU scaled down to around 360 MHz from time to time, resulting in heavy stuttering during gameplay in huge environments. That's what really bothered me, 'cause same happened with Riptide GP from time to time, just random encounters.
So I installed good old ROM Toolbox (very nice tool by the way) and enforced Performance governor.
Result of this was that cores 0 and 1 scaled very nicely during gameplay (Shadowgun), but cores 2 and 3 were shut down permanently. Really weird stuff, but the game ran much, much better with just those 2 very stable scaling cores!
My best guess is that HTC really messed up the default governor, I hope they'll release kernel sources soon, so our kernel devs can take a look at this.

Nvidia's low-level code and drivers are proprietary and have been since Teg2. So there's only so much the devs (and HTC) can do.
What you're describing is exactly what happened to the Asus Prime when the first few updates were released. Clock speeds were locked (that hadn't been) and the way the cores worked together was modified and in the process both performance and battery life were lost. It appears that in real world use the way the processors step is very different than Nvidia's marketing material.
I'd be willing to bet you that you'll observe different results using different updates. Code and drivers are going to be modified to fix the graphics issues and improve battery life and those changes are going to alter the way the processor taps and manages the different cores.
Does your phone flicker? It would be interesting to see the results of TegraStats on flickering vs. non-flickering phones. It's a shame you have to be rooted to use it because that limits the number of people who can post results.
Is there some sort of test you can come up with that people can use to compare different phones to see if the results are different? I'm not rooted or I'd help.
I never experienced any flickering so far, seems to be just fine!
Well, easiest part to reproduce is test 1, I guess. Your phone needs to be rooted, you need TegraStats from the Play Store and Antutu Benchmark.
During CPU benchmarking, all four cores are at 100% load, but they're stuck at 1.2 GHz.
Another thing that bothers me is the browser performance with web pages that include alot of different content, like the desktop page of engadget.com .
The One X lags alot during pinch to zoom, I think it's because of text reflow and constant repositioning of pictures and flash content. But with performance governor, the browser runs like hell!
I'll keep playing around with some settings, will post them here if something useful comes out.
What sort of Quadrant/ Antutu scores are you getting with performance governer?
When I test my phone they stay at 1.4 but do go to 1.5 in games but not in benchmarks, maybe the CPU has a turbo boost of some sort.

Cpu also spikes when you scroll between screens. Largely due to the carousel effect on Sense. Spikes too much imo. They need to optimize Sense for the Tegra 3.

I read that 1.5Ghz was the fastest single core speed and for multi cores the fastest is 1.4Ghz. So a benchmark using all cores will hit 1.4Ghz but a game running on a single core will hit 1.5Ghz...
"Up to Single Core 1.5 GHz /Quad-Core 1.4 GHz"
Has anyone been able to test this with the One X yet? I know it works with my Transformer Prime
"3D Stereo Gaming - This capability leverages NVIDIA’s award-winning NVIDIA 3D Vision® technology to automatically, and in real-time, convert OpenGL based games and apps into Stereo 3D."
Tried setting up Performance and my system became somewhat unstable.
Running ARHD 5.0 @ Firmware 1.29
Browser didnt rly improve in performance, too. Compared the desktop site of engadget with interactive and performance. Both performed pretty poor here.
Plus: With performance I get 1400Mhz constantly, and my phone heated up pretty fast pretty bad. In regular homescreen use I easily reached 40 degrees whereas with interactive I usually reach tops of 32-33 degrees....

2) 2 cores disabled (dual core)
as you can see with 4 cores the max was 1.2GHZ where as on only 2 cores the max was 1.4GHZ
even with setting the max cores to 1 it still used 2 cores so i concluded it wouldn't be a fair test.
I wonder if HTC have messed with the CPU working somehow? Nvidia def state "Up to Single Core 1.5 GHz /Quad-Core 1.4 GHz" here.
and the test I was asking about was the 3D Stereo Gaming
I like how with my Prime there's 3 diff settings. Powersave - 1.0Ghz, Standard 1.2Ghz and Full speed (not the actual names but I don't have my Prime in front of me) 1.4Ghz so you can set it depending on what you are doing. Plus with root and overclock upto 1.6Ghz or 1.7/8Ghz with kernal change/custom rom.

still going to count the tests as valid lol, on 4 cores my phone only got to 1.2 GHz where you posted it should be 1.4 which was only the case on 2 cores.
This is going to work the same way it works for "Regular" computer CPUs.
Core i7 scales frequencies (and does turboboost) depending on the overral load. You get the highest boost with just one core, a little lower with two, and very little with all of them (this depends on package heat dissipation and is usually set by BIOS in laptops - not sure about desktops). For computers, there is software called Throttlestop which allows you to tune some of these parameters, not sure what can be done on Tegra3.

Aye. Can't argue with proper test results. I think for games I'll stick to my Prime with 1.6Ghz max, less heat and more battery
Hi, I noted that the temperature of the CPU in System Tuner, after less than 20 minutes of playing in Dead Trigger was 71C, without charger.
With charger is worse:
After watching movie on tv screen, via mhl adaptor in mkv 1920x800 the CPU temperature was 73c, later, when I browsed the internet, was 76 C!
Is it normal and safe temperature?
When I using the adaptor, charger must be connected all the time, which probably increases temperature.
Thanks for help.

Wow my CPU is hot too but not this hot. It only gets up to about 45 C or a bit more. You should go to the repair store and let them take a look at it

I don't know if 75% is normal or not since I have bought the HOX just a few days ago and I have questions of my own regarding the device.
However, I can say that my unit had a CPU temperature of 44 degrees idle when I have read your post. I have played Shadow Gun for about 10 minutes and It reached 66 degrees.
I hope this info helps.

I'm currently on CM10+LeanKernel, and while my battery life is great as it is I was just curious to hear other opinions/settings/etc.
Now, I know this obviously varies greatly across each and every device, but I just wanted to get an idea of what generally works well for everyone?
I would try it out on my own but ever since coming from my Vibrant (It worked great with UV at first, but it would slowly but surely just not take to it anymore and I eventually just had to stick with stock voltage settings), I'm sort of hesitant to get started without others opinions.
Thanks in advance everyone!

I lower my voltage to reduce the heat being generated. I go about 125 across the board with lean and faux kernel.
And using the stress test feature on SetCPU it goes forever without rebooting so i feel comfortable with stability.
Honestly if you run supercharger scripts, remove bloat, you can keep core clocks to around 1.25max and 485 the lowest without any jitters or pauses, from my recent testing. This was on FreeGS3R6 and Trinity Kernel
I did not however find out what the lowest max clock-speed was before i noticed any slowdowns in user experience....but i will now be looking into this!

All supercharger does is change minfree values. OOM groupings and things with memory. No CPU tweaks are happening. Just clarifying
I would be very careful with UV as it can cause permanent damage to the chips. I think I undervolted my gs3 too much and ever since then my phone has been laggy no matter what rom I flash.

after my game testing ill see if i can drop any of them lower and run the test again. but certainly digging this!

I gave your settings a shot, it worked well for maybe 15 minutes? Left my phone alone for a bit, then turned my screen on again and noticed a MASSIVE amount of lag. Rebooted to get my stock voltage settings.
I'm now at -50 across the board, and seem to be pretty stable.
I've already seen some benefits from just that little UV as well.
Before the UV, I was getting ~20-25 hours on one charge. (Again, for those curious, I'm on CM10+LeanKernel.)
After UV: sitting at 61% and going on 20 hours and 19 min.
This is with Wi-Fi/GPS/sync on, auto brightness, OC at 1.67ghz.
Light-Medium usage, lots of texting, random checking of email/Facebook/instagram.
I'm definitely gonna experiment and see what my thresholds/limits are.
I'm pretty sure I can push it more.

At the very end, my dumb ass tried adjusting my UV even lower. No idea why, I genuinely wasn't thinking though. But yeah, it crashed on me which is why it randomly drops off like that.

But yeah.
41 hours on a single charge.
Wi-Fi and GPS are both on.
This is on auto brightness. This is also with lots of texting/instagram/facebook/tapatalk.
I forgot to close out of Chrome, which is why it was my main drain.
This is with me overclocking at 1.72ghz, and really light UV at -50mV across the board.
I know for a fact I can go more aggressive while still keeping it stable.
This is just terrible battery life and idk why.

Poor 3G signal will ruin the battery. As well as using that stupid Facebook app. Uninstall it and use the web browser. Also how much screen on time.

Right now it's at 54 mins.
absolutely, that damned facebook app! your screen on time is adout an hour there(it looks like). is your brightness up high or are you using auto brightnes? do you have root, what governor are you using? whats your cpu speed?
Yeah about an hour...... It was at half brightness...... Rooted....... Franco kernel milestone 6........dyninteractive governor....... 230 mhz Min. 1036 mhz max.

try ondemand/deadline sampling rate 15000 up threshold of 98%, or try interactive/sio(i dont use it so cant give you good settings for this combo). if still fine for you, lower the brightness a little more(33%?).
there are a few good posts out on the net about how to save battery life. common talking points would be
Turning off Wi-Fi
Adjust screen brightness
Turn off mobile data when not needed
Turn off Sync for apps that don't need to be always in Sync
Haptic feedback
and many more..
I guess these are the really common ones, so give it a try and see how it works for you
Actually I get way better battery life with wifi on its weird.....if I use mobile data my phone gets hot and my battery just falls!
If you have a VZW Nexus I don't think it's an app, the screen, etc. The wife, the girlfriend, and I all have the Nexus and none of us can make it through the day for the last week or so. The drain is terrible. And we don't all have the same apps installed. I wanna say something's changed about LTE because besides the hardware and Jelly Bean it's the only thing absolutely all three phones have in common. But I have no actual proof, so...
I have the sprint galaxy nexus, and honestly your battery life seems pretty normal if its a CDMA variant. I'd actually consider that to be pretty good battery life considering its a CDMA nexus
Was that with the screen on the entire time? Or mostly idle and screen off? For screen on, that's not that bad. For idle, that's a little off. Me, personally, I only get about 3 hours at below minimum brightness (modified with rom). Try turning down your brightness even more. It should help. The screen is the biggest killer of battery life on the nexus, especially because it's not optimized for it. As well, keep wifi on. Don't turn it off. It'll just waste more battery switching it constantly. Only turn it off if you are going to be using data for an extended period of time. As well, you could try a different kernel. I'd recommend trinity, but it depends on your rom and what features you like.

An hour screen-on, 50% brightness, and the Facebook app can easily chew 33% of your battery... especially if you're on a stock battery.
As an aside, how can you even stand 50% brightness (assuming you're not in bright sunlight)? 50% just seems way too bright. I typically run at 10% brightness indoors, even at work, where we have fairly bright fluorescent lighting.

True that! At first I didn't think the FB app was consuming that much battery, but I tried uninstalling it and the battery statistics have greatly improved. Hope FB gets to fix this soon, it's nice to use facebook through a native app rather than a browser. Don't you think?
Try Fast For Facebook, it doesn't offer as much as the regular app, but it's an app and it doesn't suck up as much juice.

Basically I've had a Sprint Galaxy Nexus since it launched and I've been plagued with heat issues under even light load, but under heavy load its so bad that it is thermal throttling about 90% of the time after only 2 minutes of use.
And by that I mean it is running at 65c after less than 2 minutes of any 3D game, where it begins thermal throttling to control the temperature, and every game becomes unplayable. The device can easily heat to 60c by simply scrolling a webpage but 65c is the threshold where the device is simply unusable. I know we should expect some heat due to passive cooling rather than active cooling, but in this state, my phone is only good for email and music.
So I'm ready to take it into my own hands and modify my phone. I have no idea what type of heatsink is in this thing as I have not taken it apart yet. I am hoping the issue is simply that the heatsink didn't have proper thermal compound on it and I can just treat it like a PC, but if thats not the problem, I'm wondering if this is going to be beyond my ability.
Are there improved heatsinks for phones on the market? I don't even know where to start

I'm pretty sure smartphones especially this phone don't have heatsinks lol
If you're going to modify, just try out some kernels. Most, if not all custom kernels have Smartreflex control to calculate how much voltage the CPU needs in order to run a certain frequency at the lowest possible stable voltage. Undervolting will help some heating issues.
Remember, this phone can take heat up to 100+ Celsius before needing to reboot automatically to cool down. And the TI-OMAP is not the most heat efficient processor to begin with. It is from 2011.
Really disappointed with under volting after spending 4 hours rooting my device and putting paranoid android my temps have only gotten worse. 75c after 3 minutes of a game

I think his problem is the hardware itself. He said this was a problem see he got the phone from launch. I'm scratching my head as to why he still kept the phone and didn't have it replaced. My phone runs around 55 Celsius on higher load so I think the phone's cooling isn't working right and he should have gotten a replacement.

Actually it depends mine, with a TPU cover and 35 degrees outside, heats up pretty quickly. Right now i'm indoor with air conditioned, Gnex undervolted and fixed at 350MHz, only playing some music + usb charging, and CPU temp hovers around 41C. I'll try to play with it once at home and see if the undervolt actually helped.
Also noticed that some well programmed games (such as Mini Motor Racing), despite the great smooth graphic, they heat up the phone very little. On the other hand, simple card games made my Gnex almost untouchable, go figure.
Here. Also attached is the temperature reading from TempMonitor right after closing the game in the top left
Ok so after being completely unimpressed with paranoid android, I'm torn on which rom I should try next. I had no data on PA but got that fixed thanks to a topic on here
Feimitsu, which kernel are you running? I'm using what I guess is franco kernel that came with PA

What is the average temperature in your country ? Because 60 degrees while scrolling a webpage is impossible for me to recreate. These temperatures you are having is not strange when the average ambient temperature is around 30 degrees. If that's not the case then try Slimbean alpha 3.1 which comes with LeanKernel 8.0. Make a full wipe if possible !

I'd say the average outdoor temperatures are around 75f or 24c in the summer,
