SetCPU draining battery?

Anyone else have this problem. I usually am running at 1516 with cm. 6.1.1. So the other day for ****s and giggles I decided to disable set on boot and revert to 806 mhz (stock) and man what a difference. I got 26 hours of battery life. I've tested today with setcpu on running at 806 and tfhe battery life is way off. Somethings up.

Try the app cpu tuner, afaik, any speed above 1.2ghz is overvolted anyway which speeds battery usage. Cpu tuner has worked well for me as I think the verdict is still out to whether setcpu's screen off profiles actually work. That, and I personally don't see a difference in 1ghz vs 1.5ghz in daily activities, unless gaming

Actually I use set cpu and I get about 36 hrs before I have to recharge. I'm oc @ 1.2 ghz and with moderate use. I guess it really does vary from phone to phone.

How are you guys getting such high battery lives? I was at 28% after 6.5 hours today... like wtf? And i didnt overclock or anything... I was using the phone with continuous data for about 90 minutes... other than that just texting...

Setcpu is the culprit. I would just like to know why it varys for every user. Maybe ill try reinstalling the app and see the outcome.

Yeah I get the same crap. I have CM7. Suppose to be good with battery power management. With Glacier I got 17 hours with set cpu profiles.
G2 its a joke. I got 9 hours luckily.
Now its 5 hours I got %39. Is it my phone or the battery?

Hmm I beg to differ. I am running CM 6.1 and this is my battery life. BTW I only use SetCPU to OC to 1.3Ghz . No profiles

That's very nice. I just disable the profiles and left it at 806 MHz. The battery drainage slowed down. So profiles really mess up. I have tried virtuous rom, with profiles I got pretty good for HTC sense. But I haven't gotten any close to yours.
With cm 6.1 I had %20 in 4 hours with normal usage.
Also is minimum and Max at 1.3 ghz?

As long as mine lasts the day I'm Happy

My batterry life.
You can see I'm overclocked @ 1.2ghz as well.

Diffrent pic.
Last pic of my home screen was a bit blurry so i uploaded a new one. Now you can see the o.c speed a bit better.

Why would it vary from every user then? I do have profiles setup with ondemand as all my profile governors. I find it very weird how some people are getting good batt life with setcpu running and I'm getting amazing battery with it off. Ran it off for 20 hours so far and I'm at 45 percent.
[G2/HTC Vision]

Maybe some people haven't configured their profiles properly in SetCPU? I know I didn't. I have my phone OC at 1.2ghz and had profiles set for lots of different profiles including screen off at 245/245; i was only getting 14 hours top. However, I realised that the priorities that I had set the different profiles to were clashing. I discovered this when I only the screen off profile enabled with the rest of the profiles disabled and with moderate use (few phone calls via Bluetooth, 25-30mins, a few SMS msgs, very little data, wifi switched on, 2g+3G, not much browsing) I have got 52% after 17hrs 33mins)
Thats very good battery life for me!
Try having profiles enabled but with just the screen off profile activated. It worked wonders for me!

No maximum is 1.3 and min is 245mhz interactive governor

Question why not a minimum of 245mhz. Btw the SetCpu widget is a battery drainer.

The screen off profile does more harm than good and you do not need it if you are using either the smartass/interactive/scary governer considering they will already underclock when the screen is off, the switching of profiles regularly is a real killer. Beyond that, look into calibrating your battery as well the next time you fully charge the phone. The battery calibration app is also available on the market.

supposed solution to heat during gaming .

i want to discuss the overlock or underlocking the cpu
so whats the effect on heat generated ????
overlock increase heat or dcrease heat ??
and is undervolting helps to decrease heat generated from the processor ??
many tests mentioned that overlock 1.6 is stable and undervolting scale (200-800) is also stable but non of the testers mentioned the heat effect all are reporting for stability and speed
i suffer from heat during hd games and i know it is normal but i dont want the phone to get hot during gaming i closes the game after around 30 minutes due to this problem

If you want to reduce heat during gaming, then you need to change the 1.2GHz speed (level 0) down to either 1.0GHz or 800MHz. Changing the Level 1 to Level 4 speeds won't solve your problem since your CPU will be at full speed Level 0 during gaming.

No that's just bull****. Go play around a few games and have CPU Spy running and after a gamsing session check the CPU states, rarely does a game go over 800MHz and most of the time spent is on 500MHz for most games. There aren't any games out there that need the computational power of higher frequencies and that's why their time-in-state is procentually so low.
If you really want to reduce heat, then you need to undervolt your GPU which right now is only possible with a Tegrak compatible kernel, which is frankly speaking out of date, or you wait a few weeks until the Ninphetamine team finishes GPU voltage control interface and then more kernels will be able to implement that.
While undervolting with Tegrak I was running 160MHz/750mV 266MHz/750mV full stable (default voltage 950/1000mV, 750 was minimum configurable). It was running full stable and while on default the back of the phone would get really hot, while undervolted it was just warm to the touch.

so is there any effect on device performance ????
after undervolting the hd games performs properly as stock ?? and without heat ?? if yess i will root now and see what can i do
and how can i know that my kernel is tegrak compatible ?? it is kg2

Changing voltage has no effect on performance unless you undervolt into unstable values and make it crash. Stock should be compatible with Tegrak (I think???). Just check out the free app in the market. The stupid thing is you need to pay for the full version to get GPU control and that's why it's unpopular, so maybe it's just better to wait for Ninphetamine GPU control in a couple of weeks or soonish and have it for free and get a good kernel to go with it.

thanks bro
but i think i have small thing that confuse me undervolting is different from downlock ??
and what is the relation between them ??? i think certain volt will give related amount of "Mhz" ?? is that right ??? so set cpu is the same effect as tegrak or what ??

Tegrak, basically gives you more options such as GPU clocking and custom tweaks. SetCPU is ok, but I just use it for controlling clock speeds. Also, you can set oc'ing, max at 2GHZ, but you have to play around with stuff.

Use a very thin case and you'll never notice.

Sure. I just fired up Plants vs Zombies, which is not the world's most demanding Android game and played 1 quick game, taking about 10 minutes. While playing, the back of the phone just where the camera is became warm through the phone case! Tell me why I have the phone running at 1200MHz for such a big portion of time if my post is just bull****. This was also the Last Stand level, where you get a pause in the middle of the attacks to replant.

35% of time on full speed does not equal all the time on full speed like you said in your first post. It's still 50% on either 800 or 500MHz like I said. And you took a bad example as I dont even know if PvsZ is even using properly the GPU, and then might use only the CPU. Go play Gameloft HD games which are the most demanding atm and max CPU ratio to the rest falls down.

so what ??? at the end undervolting will help or not ???
i need it for hd games
and if the cpu need to be at 50% of time so it need to use 1200 mhz 50 of time so if we fixed it to 800 or 1000 or 500 this will affect performance

no heat issues
I have ninphetamine kernel, underclocked to 800 and undervolted, I haven't noticed any heat issues since then when playing games and noticed no slow downs. Games tried: HeavyGunner, Zenonia 3. Also no heat issues anymore when playing flash video in a browser.

but sorry these games are not using graphics as eternal legacy or asphalt 6 hd or fast 5 hd

really it works
i rooted then set cpu then put the values 200-800 and asphalt 6 worked around 20 minutes no heat at all only slight warm
and the benchmark only decresed from 3300 to 2750

My battery is now just terrible.

I have had data on for a huge chunk of this time and played shadow gun for 10 minutes. I'm over locked to 1300 Max 800 Min on ondemmand. Auto brightness, disabled auto sync, and all the other tricks you can think of. With data off I can pull off an extra 6 hours without games. What is this horse s**t?

Nexus S - CyberGR Hybrid ICS (5), Matrix Kernel (15.5)

Try Eugene kernel with luzuactive. I am having good battery life with that.
Sent from my Nexus S using xda premium

That seems fairly normal to me on ICS; maybe even better than what I can get. I can only get about 2.5 hours of on screen time + 20 hours idling.
You have about 4 hours on on screen time and no idling. Seems about right.
However on Gingerbread you could probably pull off more on-screen usage.

I was able to get a lot more out of it a week ago... The same things I do now I could do for 4-7 (+some off screen use...) hours, off screen would be MUCH better... It just suddenly stopped being good. ICS wasn't always this bad lol

For starters your min is 800 MHz.... What the heck?! Who needs that? I'm sure that and being OC'd to 1300 hurts too.

So should I drop all the way down to 100, or go for 200 or 400? 100 seems blegh to me. I'm thinking of 200? I am however keeping the 1300 . If I must I'll go down to 1200.

Kernel is definitely not the problem. I've ran matrix before and its had some of the best battery life.
Problem is with your 800mhz min. You definitely don't need that. Run it at 200 and the difference won't be that significant.

Okay thanks . So I'm going to go for 1200 / 100 on the speedy 7 kernel (lulzactive)... Good? If it works out eventually I'll switch back to Matrix 15.5 and see the difference. I've heard Trinity is very good
Just waiting on a full charge will post results when they come in. I'll be doing some very heavy usage because that's what I'm concerned about.
P.S. I've enabled Auto-Brightness after "re-thinking" the advantages to it in terms of battery use + screen visibility.

With smartassv2/sio on CyberGR & Eugene kernel I'm getting the best battery performance I've had ever since I put on ICS. At this rate I can hit 3 days idling. With heavy usage, probably 6-8 hours? Try it.

Set min freq to 200 first off. 800 min is way too high if you want to save battery.
Secondly leave deep idle turned off, it doesn't do anything on ics.
check out bedalus battery drain comparison.
I get around 4 hours of screen on time for about 12-14hrs on battery.
I also undervolt more than the kernels are already undervolted.

I already have a 100 min on-going so I don't want to mess up the test . Afterwards I'll do 200. As for deep idle the option on my NS Tools has mysteriously vanished so I won't be able to enable it either way . I'm not going to touch under voltage I don't know much about over clocking (besides it speeds up your phone) as is. Lol rather not get into another hole

I read somewhere that 200 is better than 100 bit the only way to know is to try it out!
That's coz speedy doesn't have deep idle. Nstools doesn't show options the kernel doesn't have.
Well if you wanna try undervolting just uncheck set at boot in nstools.
Then search for stock nexus s voltages and see what they are and then look see what yours are and work from there.
The worst that will happen is that your phone will reboot but it will boot into the kernels stock voltages because you unchecked set at boot! No harm done!

Are you running the kernel with the 65 fps hack or no?

Major Speed Increase

I have noticed this phone underperforms compared to other Snapdragon 821 devices and I have found a method to majorly increase the speed of this device.
After the following changes the device remains running at cool operating temperatures and performance is increased over the board about 50%
Doing these changes will disable the useless thermal limits set by Xiaomi on this device. Xiaomi set the limits far to low unlike other manufacturers.
The device still has hardware thermal protection by Qualcomm so there is no chance these changes will damage your device.
Your will need:
ES File Explorer
Kernal Auditor
Root Access
Open ES File Explorer and navigate to System/etc
Scroll to the bottom and find file thermal-engine-8996.conf
Copy this to your sd card for a backup and delete this file. ( This will not take effect immediately )
Go to Kernal Auditor and change the big core CPU Governor to OnDemand and set the Maximum CPU frequency to 2150MHz.
Set the LITTLE core CPU Governor to interactive and Max Frequency to 1593MHz.
Go to GPU and change the GPU Max Frequency to 560MHz.
Restart your device for these changes to take effect, the changes are astounding and matches the performance of a stock Snapdragon 835 device while still running at standard operating temperatures.

are u sure, we will have same thermal sensation ? i mean in hand ?

Wont it make the device very hot and will have very fast battery drain?
Sent from my Xiaomi MIX using XDA Labs

The device doesn't get any hotter than usual with these settings.
It is important to under clock a bit so it can keep this sustained performance without breaching it's thermal limits.
The performance gains are very noticeable especially with Dolphin and PPSSPP.
You can see how hot the device gets with Kernal Auditor. Compare the heat listings before the changes and after these are done to check for yourself.
As long as you use these settings the device will not get hotter than stock.

The device doesn't get hot if you underclock the cores and battery life is even better because you are underclocking the GPU and LITTLE core which don't need to go up to 2.1GHz for standard tasks.

So there are no downsides? :silly:
Sent from my Xiaomi MIX using XDA Labs

There are always down sides to system modifications that haven't been extensively tested, his mileage may not be what you get - be very careful changing core restrictions / settings.

I find there can be considerable variation based on the ROM. I have found EPIC to give the most consistent results. By results I mean Antutu, since general performance is hard to measure.
I set the cores to their max and the boost frequencies to max too. Governor is on demand for both. Response after touch is set to 100ms. In the thermal settings I have Temperature Throttle on and the GPU governor to performance. I get 155k In Antutu almost every pass. Sometimes it'll top 160k, other times down to 150k.
I don't care about the heat since I almost always use the included case and I'm not concerned with battery life. The main thing that still bugs me is the temp figure in Kernel Auditor. It'll show high 60s after Antutu, but other temp apps like CpuTemp show it never gets above 45C. What does your temp get up to?
From what I've read, even in the 60C+ range it's still within safe/reasonable working temps for the CPU. I've used these settings for around two weeks​ and I've gone out of my way to game when I rarely did before (sometimes 1-2 hours in PPSSPP which taxes it). Never had it freeze/lock/reboot once. My Nexus 6 would occasionally do that when I had it pushed to the limit.
If I didn't use the case then I probably would back off it a little as you have outlined as the temps when holding the bare phone can be pretty hot.

I find there can be considerable variation based on the ROM. I have found EPIC to give the most consistent results. By results I mean Antutu, since general performance is hard to measure.

Kernal Auditor gets the actual CPU/GPU temps , I'm not sure where apps like CPUZ or CPU Temp get their readings.
Even after running Dolphin or PPSSPP for a couple hours the CPU temp gets into the low 70's but that's as high as it goes.
These chips are safe to run up to 95 C for CPU , 100 GPU and 110 C for the battery.
Changing these settings keeps the device well within it's thermal limits.
I have had my phone set like this for months after running it many other configurations.
I just had to tell everyone about it because it beats my buddies OnePlus 3T quite a bit when it comes to gaming.

Give it a try and see for yourself.
I recently upgraded to the latest epic ROM version and found my phone to be running extra slow and battery wasn't lasting as long.
Turns out the update had reverted my settings so I decided to post this thermal "fix"
I highly recommend everyone make this change really , there is a reason that OnePlus decided to underclock their OnePlus 3T and why it runs much faster than the Xiaomi Mi Mix before this fix is completed.
It's all because the thermal throttle kicks in much too early on the Mix due to the extra heat at max Mhz for the GPU and large cores.
The only way to change this and get the performance enhancements is the remove the thermal file as I posted and follow the steps to ensure good thermals.

Thanks. Done here. It got REALLY REALLY fast but so warm for now. I'll wait to see if it get colder...

Tried these mods right now.
Simply wonderful.
Antutu from 130.000 to over 157.000
Increased speed
Now all is very smooth
But the temperatures, incredibly, are gone down...this smartphone now is more fast and more cold.
Xiaomi/Qualcomm thermal control is so bad?
But there's a strange issue with Kernel Adiutor: I set the frequency, governor etc but, after reboot, I see these settings returning to original values. Is it normal?

I also have this problem.
I have set everything and the "Apply on boot" is on but everything is going back to the original values.

Really? It was so warm here. Like 80 degrees celsius. Would it be cause im using RR?
Sent from my MI MIX using Tapatalk

I had the same temperatures with miui, RR and Lineage.
If I delete that file in every rom, i think I have the same results: more speed, less temperatures

I will try this settings on My MIUI ROM...
@ all...
Tips to have Kernel Adiutor to apply @ boot value (on MIUI ROM i mean)
Go to security center and manage permissions for this apps like auto startup authorized after restart i see a notification with time which say, i will aplly your value in xx seconds... and it works...
@NGP-1001
Thx for your feedback and tips, will make some test on my daily usage and send my feedback too...
Cheers

Dolphin the browser? The only other Dolphin I know of is the one for GC/Wii emulation.
Low 70s is as high as mine gets too but it can get uncomfortably warm without the case. Maybe it's just when the CPU and GPU are both being pushed that the heat builds more. If I just use a CPU-only benchmark, like GeekBench, the phone only ever gets moderately warm at most.
I was really disappointed with the general stutter and performance (just in the UI, not even gaming) before I noticed your old thermal post. I can't recommend this method enough. Getting rid of the thermal.conf makes a massive difference no matter if you underclock it or push it to the max, even if you're taking a hit on battery life.
For those on the latest EPIC, the integrated Kernel Auditor is gone, so it needs installed from the Play store. Even then it won't work on boot like the old one did. You need to go into Settings > App Settings > Permissions > AutoStart and toggle it on.

Great result with performance governor

O, i need agree, device is much smoother then before, if u don't play, u will have a standard temp ° but i try to play Battle Bay... Got damn, baby...
Hot like a woman in video clip from old west coast sound... 84.2°... based on demande request, if u play, device come hot, other it's cold...
Will try more time to check if i can adjust temp limit to reduce speed based on temp limit...
Cheers

If anyone is still getting higher temps I would try underclocking a bit more. You will still get the speed increase even at much lower MHz. I wouldn't use the performance Governor as it's a huge battery drain.

So.. why should someone Overclock his Phone?

So here’s what I got: It’s not about getting more power out of your processor. It’s something else..
As a PC Overclocker, getting more power out of the Phone’s processor was the first thing I thought was behind Phone Overclocking. But that should be impossible right? I mean.. how the hell are you gonna cool that thing? You can’t.. And it is. That’s why benchmarks give you the finger after you OC your phone. At best you’ll get about 15% more “points”, which of course is laughable.. But then again why do people do it? Is it a fetish? Well it’s not. It’s about these three things:
UI Reaction Time – UI Animations Smoothness – Memory Management
Three things that determine the quality of your daily experience with your phone.
Every vendor makes his own adjustments to the Kernel that determines the behavior of the hardware in response to the software. Some make it right, some don’t. And when you find yourself hostage to the latter, the only way you can break free and restore your phone’s true potential, is with a custom Kernel that allows you to adjust it. And it’s not even necessary to increase the frequencies! Tightening the timings, or even better eliminating them, can make all the difference in the world! But since a Mobile Chip has a built in protection against overheating, and raising the frequencies could not possibly harm it, then what hell.. why not?
And that god damn memory management that doesn’t let you have more that 4 - 5 apps in the background, even though you have 4 GB of RAM!.. what the hell is that! Well you can fix that too.
So you see, appearances can be deceiving. Phones are different creatures that the PCs. We do different things with them, so we need different things from them. And if you’re willing to give up just a little bit of your battery life.. man..you will NOT wanna go back!
So that’s it!
PS. Speaking of battery life, there is also that thing called “Underclocking”. It can even double your battery life, but of course the price would be the exact opposite effects of the above. Every man has his poison!..

That is false. Even with thermal protection, the lifespan of the cpu can be drastically reduced if its overclocked and constantly running hot.
And many users overclock in order to get a better experience playing games.

That is true in general. It's called electromigration and it doesn't matter if you cool it well enough. It is caused by the increased kinetic energy of the electrons. But phone CPUs don't get stressed enough to see it happening. Even in PCs where actual overcloking takes place, it would take many years to actually see it happening, and a very serious increase in performance.
So in comparison one could say that it really is safe.
One interesting thing that someone said to me last night though, is that custom kernels don't have a perfect temperature throttling when necessary. So one should check the temps in the initial stage of testing to make sure that it doesn't get too hot.

I would've disagree with that. Overclocking used to work reasonably well a long time ago but for about 10-15yrs the headroom in desktop cpu's have shrunk and overclocking does not give stable results. My own experiences coincides with what I've heard with people who work in IT who build/sell pc's - overclocked cpus will encounter much more errors and intermittent problems and will require resetting back to stock clocks or even underclocking in order to be stable.

Check this out for example: I underclock my CPU to 1689MHz from 2000MHz, but I change the governor to Performance, which keeps the cores constantly to that frequency WHEN operational. The result is a MUCH snappier behavior with no apparent latency, zero stress to the CPU, and battery compensation by the lower frequency.
Could you do that otherwise? That's what I'm talking about! Full flexibility!

Thats not overclocking and you did not talk about flexibility. Even the title of your thread says "Overclock".
You said overclocking cpus on pc's and phones were safe and would take "many years" to see any degradation.

I said both of them, and they do not conflict with each other. I explained it in my first post.

Underclocking is a bad thing. unless you can't overclock much because of battery and temperature limitations, underclocking is not recommended. It depends on your governor, a stupid governor will slow you down and be visible on weak devices. your case is due to have stupid governor in phone, but suitable with strong device & want to save battery but don't need to lock freq at maximum

cpu will not degrade in life no matter how high frequency, overclock and runs continuously but its life cycle will be affected by high temperature and high voltage
