Undervolting CPU - More battery... - HTC One X

Is it worth it?
How do I go about testing the stability of the phone ( I don't want to reduce clock speed )

If you want your phone to work perfectly without loosing speed it's not worth it ( change wouldn't be noticeable )

Does undervolting really lower performance? You're sure you're not thinking about under clocking?

I predict a "my HOX isn't working right, I blame HTC" thread shortly after you try this.
But really, what are your expected gains from doing this?

If you're not sure about what you are doing it won't lower performance it will probably result in a lot of crashing and error messages, I personally think it's not worth it for the amount of battery you could gain ( few minutes )

Well, I have had it undervolted with -150mv in a week or something and I haven't experienced any errors and crashes. I don't have it for the battery, but for the temps.

I've been under voting my s3 747m for over two weeks now, between 75 to 300mv lower, at 1.89 I'm running at 1200mv, although I'm only running it at 1.5.
To test it I use Stability Test app, on scaling for 3 hour runs, it will stress all frequencies.
If you find a crash you increase the voltage at that frequency, BUT, the best way to test it, instead of using scaling test, use the burn in one, but manually set your speed and let it stress test XX frequency for a long period, this Is where I found the most of my crashes.
This isn't an easy or a quick job, it'll require a good weekend of mucking around. I have all my speeds down to 5mv increments instead of the stock 25 the apps give you.
But so far, I don't get voltage related crashes, only the random KP caused by cm10 bugs.
If people are interested in the voltages for this phone I could post them

I'm uv @ 1137 and oc @ 1.6 using arhd 9.1.0 faux 006u kernel and the phone is running better than ever
I use mhl hdmi with sixaxis and the battery used to die in a hour and it got really hot but now I played for a hour before work and it used 40% battery and it was warm but not overheating
But before u go playin around with things look into it all cores are different and behave different

On and off system lag. Is it related the amount of apps installed?

I am currently running mikG 2.45 more freedom. Titanium backup loaded 335 Apps, which include system apps. I am thinking the maybe 200+ apps I have installed are the reason for the on and off lag.

Apps maybe be paying apart in it but you say your running "more freedom" try running the stock freedom not the more or less or extreme or whatever he calls them. The undervolting may be limiting your processor. Also use set CPU and try to overclock a little. Im running synergy rls1 with stock freedom overclocked up to 1152 smooth as a whistle and battery is through the roof. try stock freedom and if that dont work pm me and ill help u out more if needed

I was going to try aggressive freedom on the old one and 8.5. Wow overclocking to 1152 I thought that would drill my battery into the ground.

Overclocking doesn't really show a noticeable impact in my experience. Only if you are playing a CPU intensive game that pins your CPU at 100% then it drains slightly faster not to bad tho. Also if you use the "interactive x" governor it manages the cpu's frequencys to try to keep them as low as possible so you only using enough to do a task instead of going 100% for something that doesn't need that much power. It also keep the CPU at the lowest frequency you allow it to be when you shut off the screen. So if you set your Max to 1152 and min to 245 for example. When you shut off the screen it will stay at 245 and not jump around. That tremendously helps battery. It about 8p.m. here and i have had ghis on since 7 a.m. and I'm at about 30% and that's with quite a few text, 2 - 5minute calls, about 20 minutes of games, and an hour of music. The only bad thing about overclocking is that if you go overclock to far for to long you can fry your phone. But ive been running 1152 for about 6 months and perfectly fine so i figure that's pretty good. If u have more questions or need help pm me
Edit: i forgot i also had about 20 min of internet/xda browsing on wifi and the past 45min on 3g doing the same thing haha

Underclocking One X

guys i was wondering if anyone tried underclocking one x ,what battery life got , and its it worth it?
and can i underclock tegra 3 ? will we be able sometime?
i know maybe its a noob question but i really want to do something about battery life..
thnx in advance.
What kind of battery life are you getting anyway? It's pretty decent as it is right now.

haw many days do you have it?
A week almost. (6days)..
I know.maybe its new but i dont know what the normal.is.
But i would like to know about the undercloking , if its available,if its help, and some.opinions.
if you're on the new update or have that power management fix installed, then i don't know. it's an app or a battery problem. i don't think we can oc/uc until there is kernel source, and i don't have knowledge of HTC history on that. if it doesn't improve in a week and you aren't running a bad app, then maybe exchange it?
Set CPU doesn't work on the one x so I tweeted the maker and he said he will try look into it, really needs kernel sources.

I tried underclocking to 1GHz using SetCPU.
I used the phone an entire day with the SetCPU settings and compared it with other days.
I didn't get much different results, maybe we need a custom kernel?
I've been getting about 3+ hours screen time at 30% brightness at 1.26 Haven't really checked on 1.28 yet.
Most CPU apps don't work on the One X, tried some of them but CPU Spy still shows higher frequencies been used despite underclocking.
i really want to play games (like fruit ninja,temple run, angry birds) and i thnk those games doesnt need that power to run properly..
any way to underclock or undercore(will be available?) so not much battery drains when playing?

Try to install the app called tegrastats and you will see that while playing those light games, either 1 or 2 cpus are shut off or the frequency is dropped. That's the power of this socket, it will automatically adjust to the task at hand.
I agree, however, that there is a lot of room for improvement but that will hopefully be fixed when developers can work on a custom kernel.
is not possible make underclock yet?

[Q] SetCPU - Extra Info?

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps
Thanks man

How much battery life can you save using setCPU?

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough

How much is safe for overclocking?

I'm running Blackout v3.0, and it's running pretty smooth at first. But now my phone is stuffed with bunch of apps, making it running slower and slower. I want to keep those apps so I'm willing to overclock but I afraid of damaging my phone. So I would like to ask what's the safe overclocking frequency? I want the optimum frequency, fast enough and safe/stable.

Any overclocking can be unsafe as it can shorten the lifespan of your memory and CPU. But with that said I run mine at 1200 with no issues. Most people don't go higher than 1600 but anything 1400 or lower is not going to burn it up too quick IMO. Everyones hardware will react differently though.

They usually say phone will get damaged, but I think its a myth. You can go up to 1600. After that it will get unstable.

I run IceColdSandwich and have found 1459MHz to be the best combo of performance and stability on my phone. Every phone handles OCing a little differently, some can reportedly take over 1600 without a flinch and others will lock regularly with even a slight OC. Just experiment with the "set at boot" option turned off until you find something that works reliably on your phone.

I think OC can affect battery drain only if you use an application which utilizes a full cpu load. But, if you're using this app in normal mode, economy will not be great also. So, when you using your phone for calling or general usage you will not see any problems with battery discharge.
I'm using DHD with Blackout v3.0 and I set 1200Mhz for maximum cpu value. I have no problems, phone is stable. Some time ago I used Leedroid ROM and set also 1200Mhz, but phone was rebooted by itself very often. More than twice a day.
You should try to use OC, as someone said above, without "set on boot" option. I think there is no danger for hardware up to 1600Mhz.

Not under normal use. There's a school of thought that says even though the increased speed requires more power, it can also finish tasks and go back to sleep faster, so it ends up being a wash. I've overclocked all three smartphones I've owned to date and haven't experienced any significant difference in battery life.

They say that as a precautionary measure just as they say flashing a custom ROM can be dangerous. For people who don't know what they're doing. But precaution aside, just like you said you can go up to 1600 MHz safely on this phone. I know every phone behaves differently but on average no one has issues upto that frequency. But above that frequency the phone might be unstable. The CPU will be drawing much more power at high frequencies and will heat up more. The CPU heating up too much and too frequently reduces the life of the CPU. So it's not a myth.

i think what i am doing is called underclocking , i am just making max clock speed 1 ghz
that sudden rebooting means you're doing something that crashes your phone... probably the underclocking that causes this.
bit weird though as the hox has many speeds at which it can run, 1ghz being one off them.
Are you sure you didn't also undervolt your hox and that you're using an app that is 100 percent compatible?
Try running the hox at standard speeds to make sure it's not a hardware problem and using an other app to make sure it's not the app causing problems.

strange, but as your not experiencing any problems after uninstalling set CPU it probably has something to do with it... maybe it's a wrong setting / are you sure set CPU is compatible with hox?
Try contacting the programmer of set CPU about this, or try another tool.
undervolting means setting a lower voltage than standard for your hardware, in this case the CPU.
This makes it spend less energy and thus generate less heat. Undervolting can be used as a battery saver (use less energy) just as underclocking.
