Undervolting my sensation - HTC Sensation

I'm a noobey and I really don't understand how to undervolt my phone could some explain how to undervolt a sensation for better battery,etc.I would greatly appreciate it.

Under voting works by reducing the amount of power drawn to the phone at a selected frequency. You can do this with an app like system tuner or setcpu. However I can't give you a set of voltages for it, because usually there's minor differences in the hardware of people's phones, which means some values may work for some and not others. I would advise to try reducing the values slowly, and do some research on other people's values to see what they have been able to reduce to.

Is this undervolting I use CPU set and I keep it at min 192mhz to 918 MHz.I thought this was called underclocking.Am I wring or correct.How do you actually set stuff to mv?I don't see and settings on there for mv.and what are all the different things that I can actually down set the mv on.could someone please explain alittle more.
Sent from my HTC Sensation 4G

What you did is underclocking, which saves battery but also reduces performance. Undervolting needs a kernel that supports it. You can set the mV for every mHz. I usually put it 50-62,5 mV lower than the standard voltage.

@ mesaman2012
Download System tuner (or Buy its Pro Version)
Start System Tuner.
Tap on "Voltage" button (in 2nd last row)
there u can increase or decrease the voltage (by -12.5mv to +12.5mv)
after u got ur desired voltage Tap on save to save it.
Simple....isnt it ?

I set all the setting to the lowest +12.5 volts.I hope that's alright.any input on this would be greatly appreciated. Thanks!!!

I don't know what exact voltage u have set....but whatever u have set, give it a little time to see whether it is stable or not....good luck.

Now download stability test from Market and run Scalling test,leave it for 15-20min,if its stable undervolt one more step the again stabity test for 15-20min.When test crashes rise voltage for one step and thats it

I dont rely much on undervolting for saving battery i mean it just depends on your usage mate or either way get an anker battery

Does the way I have my phone underclocked matter with undervolting at all?I keep my phone at 192mhz to 918 MHz for just normal use.I undervolted everything down as far as it would go then I +12.5 and when I was using it right away my phone shut off.so I then did another +12.5 and now so far its running alright.I'm going to do a scalling stability test next.If I'm doing anything incorrect let me know please I'm just a noobey. Thanks!!!
Sent from my HTC Sensation 4G

The only way the underclocking influences the undervolting is that you have less mHz values to set the mV for, so for example if you underclocked to +/- 1200 you can't set the voltage for 1500.

Who has undervolted there sensation and seen a noticeable gain in battery?would you say you got and extra he or 2 on a full charge?

I'll try to report back in a week or so. I went from running the standard 384-1.51 to 384-1.72, to now running 192-810, testing undervolting as well. Will have to play more for sure.
Previously, I had the screen off, not in call max frequency set to 810, while screen on was stock xe. I noticed quite a bit of time at 810, so something is consuming excessive cpu clocks when the screen is off.
The major bummer I'm coming across is that system tuner cannot undervolt below 800mv. Since the phone is ideally spending most of its time at the lowest fid/vid state (192 or 384 for example), there's a good chance of stability below 800mv. I haven't done too much research yet to see if this is possible with some other means, but this may help a bit in standby. Of course, if I could just keep the damn screen off, I'd probably be in better shape.
How much less battery do AMOLED screens consume? Saw a One S today, and it does look pretty damn sleek.

Thanks. I've been running Faux's kernels ever since I got my Sensation. I wonder if he'd consider adding the feature. How low are you able to go stably below 800mv and at what frequencies? Figure if I'm going to be idling at 192 or 384mhz, I'd like to get that voltage as low as possible.

Thanks for all the great input.should I change to a bricked kernel?If so what version.I'm running v008b4 faux kernel right now should I use a lower version like a v005?

I'd be EXTREMELY careful running your CPU at that speed. 1.5 has been considered "safe" by most people, but anything over that and you're tempting fate. Sure, it's cool to see your phone running at 1.8 or 1.9ghz, but your CPU is going to be forced waaaay out of its specifications and it's possible to damage it beyond repair. This is especially true if you are over-volting. Heat + Voltage = CPU Killers. However, even if you aren't over-volting, it could still draw more power than it was designed to do, thereby increasing heat, overstressing CPU and power supply...
So yeah, be careful.
Thanks man i just OC to this point to se what this phone can do i think this is the first and last High Quadrant can reach becauce later on the day i try to repeat the same benchmark and no reach the 3400 points. I think the CPU was enought stressed and now cant handle 1.9 Ghz. freq. but is cool. Right Now im running with LordMod 4 CFS clocked at 1.3 Ghz and works greathe. this give me 2700 +/- Quadrants and its enought power to make all kind of task and apps running a breeze.
Running any LorDMod kernel results in no wifi for me. I'm being lazy with manually pushing the .ko file though, so I dunno.
WiFi works fine here. Im. Use cyanogen mode 7 with lordmod 4.0

You'll need a combination of a custom KERNEL (that supports O/C) and a custom ROM (some come with an O/C daemon built in)
time for some reading.
Ok, so one more question just in case. May I use any ROM with any kernel or I have to match ROM to kernel (or opposite)?
Generally I would say custom roms come with the most suitable kernel.
The easiest way to overclock is to simply download an app from the market that will o/c your cpu.

Although I'd also as that unless you'r e intending on playing games then the desire s should be fast enough without over clocking as ultimately that will reduce battery life.even the sense 3 rooms when configured and optimised correctly don't lag at normal operating speeds

You're still on stock ROM right?
If so, install this kernel from recovery and SetCPU once done. OC away.

Yes, it would go a little faster
Seriously tho, it might run a little hotter, for a shorter length of time, and be slightly less stable - all depending on how much you overclock it, what settings you use, etc.
Try downloading an app from the market that will overclock your cpu and see what happens.

And NEVER max the oc setting. Some kernels allow up to 1.7ghz but your phone would be fried in a week and be incredibly unstable. Can't recommend going past 1.2ghz if you want your phone to last til your next upgrade date. For the most part though, oc is unnecessary on this phone.

I just read somewhere in other forum, if I overclock my phone, I will have problem on my phone.
Maybe because of the cpu overheat or what?
Basically, yes.
Why not use the phone as it is, and see how you like it? If you do decide to overclock, do it in small increments. Honestly, I find it fast enough at normal speeds, playing games, browsing, etc.

+1 to you. 1Ghz already fast enough. No lagging at all like some other phone.

I was quite interested in this overclocking buisness. I overcloked my phne to 1.7ghz, used it for a while and it froze twice, requiring a reboot.
There was definitely a speed incresas, but 1ghz on lbc mod is already plenty smooth!
Now I've set up setcpu profiles to have myphone only overclocked at 1.2ghz when its chargingand I'm using it. But also a profile to limit the temp at 41degrees to 825-245mhz.
But when its unplugged, u have left it on default at 1024-245mhz on demand. Great battery life compromised with great speed.

Maybe you'll need a voltage bump at 1.7GHz. But even if it's stable, it will definitely be hotter. Not good for long term.
1.1-1.2GHz should be stable for daily use.

Not really. As faux say not all chips are created equal. I've seen up to an amazing -150 but my phone can only handle -50 stable and -75 sometimes with a reboot or two.
Sent from my HTC Sensation 4g using xda premium
Mine handles -100 just fine, but yeah,others can only go -50. Just use system tuner and hit the -12.5 till your phone freezes, then when it restarts go one less and see if it's stable. That's what I did.
Sent from my HTC Sensation 4G using XDA App
I'd also suggest keeping the Max Clock at a consistent value while you play. E.g. UV -100mV might work well at one Mhz then fail at a higher value.
Mine seemed to work consistently at about -100mV, then again I tend to UC unless I'm running CF-Bench or something
Should I only need to concentrate on the lowest and highest clock speeds it's been set to use? Or will I have to undervolt all other frequencies between the two? Not sure if it increments on usage, or simply toggles between the min and max.
If it does increment, how can I test it's stability on the other frequencies if I can't tell what frequency it was using at the time?
Just tapped the -12.5 button a few times, and it reduced all of the sliders. It's -100 now with no apparent issues as of yet.
May I ask the reason for undervolting?

I run faux latest version 2.7 beta and I see his scripts to undervolt and the lowest I see it too go is -75 how are you able to go lower to -100.... ???

If the phone hangs/boots below that level then with the Phone/Kernel/... that's the limit.
I created a GScript script (well a sh script) to U/V after a reboot. I didn't want it to do it automatically as you'd end up in a boot loop. Just hassle to fix. The reason for the GScript was to remove it from the various CPU controllers I'd tried, I ended up just using the CM7 one to control the CPU.
Faux has the command to do it globally (across all frequencies) or individual frequencies. TBH I never bothered with individual ones.
The bottom line is, do what you and your phone are happy with.
EDIT: meant to add you can check the actual value manually. I know the Faux one (same post as the scripts above) but if you are using a different kernel it might be in a different place.

Best settings for SetCpu in Htc Desire S

Can anyone tell best settings you guys are using in Set Cpu
Thankxx

Best in terms of speed, battery life?
best thing is not to overclock as this can reduce battery life, so i use 2 profiles in addition to the normal one which is 245-1024 scaling=interactive, the other two profiles are
245-768 at screen off scaling=conservative
245-368 at battery<16% scaling= conservative(u can try powersave but its too slow then)
hope this helps
i have little problem. even if i set intercative 245mhz-1ghz after one day or simply later it freeze at 245 mhz. phone is then very laggy and i have to change profile to get it to work again.

yes probably a bug, never had this problem try changing the scaling or do a clean install again, but interactive is more cpu aggressive so it provides better performance
What about overlock
What is the scale to have it

overclocking depends on the kernel you have installed, most of them have a max of 1.5 ghz("Safe" limit), but generally its not good to overclock for the battery and for the phone itself unless for a short time and you can use whatever scaling you feel appropriate.
as for the other questions , i have no idea about those

under volting and over clocking

I downloaded android Turner pro...what an amazing application ...anyways I noticed or rather we all noticed that the HTC sensation phones always over heat and hmmm battery our greatest problem...but still some people wont mind still over clocking the amazing phone...respect to this fone bcux irrespective of the fact that its two years old....it still beats most recent fones hands down and also in my opinion even iPhone 4s can't do most things this fone does...there fore iphone4 can't beat our rooted HTC sensation devices lol if im wrong tell me
ok now lemmi get to the point ,I am presently using semsation v5 Rom.... thanks to kerneldev,the room is sleek and nice...I love it. Using sultan kernel r24b5....I over clocked my HTC XE to 1566 CPU frequency and undervolted it by -64MV the phone was fast...yes but the heat was evil lol ?? and battery life wasnt so impressive ?...so here was what I did to reduce the heat a little...
I downloaded Turbo boost mod 3.v
flashed and install via cwm
then I downloaded android tuner from play store
then I underclocked my phone with the Android tuner to 1182 CPU frequency (this is the default CPU frequency for HTC xe)
then I undervolt using android tuner to 950mv...I pressed save and renamed the setting using android turner...then I pressed on boot by the top left corner of the android Turner screen...I went back to setting the CPU frequency and marked the 1182 settings to on boot also....now reboot the fone.
im a heavy user...my 4g or H network signal is always on....my phone stopped over heating like before...but it still get hot tho...
also u can still keep undervolting with the android turner...but if it gets to the voltage that ur phone's CPU can't handle...the phone automatically reboots itself and set itself back to the default CPU voltage....awesome right?
note: this is just a suggestion....im not responsible for any faulty fone tho and do nandroid backupw as usual...
if I helped for those complaining about over heated fone pls click the thanks button ? cheers?

Hi, Stock Sensation is 1188Mhz, XE is 1566Mhz ....
you can Also Downclock at 972Mhz for max and 384Mhz for min.
Stock fréquencies will be Undervolted normally , I think that its not necessary to undervolt our Sensation.
To what temperature reached your mobile????
I would not recommend downclock below 384MHz for minimum. I had lags and reboots.

That depends on the hardware in your device. Just because all the chips come off the same assemply line oddly doesn't mean they are all created equal.
I run mine at 192 min and have never had a reboot as a result of it.
Other people can put it on 192 and it'll reboot every single time over and over until they raise the min speed.
The only way to see if your phone can handle 192 is to try it for a day and see if it's stable. It might be, and it might not be. If it's not, there's probably no settings changes you could do to make it better. It's probably a hardware thing.
I have no problem with the minimum frequency of 192Mhz, but as I have to test several Rom, I just prefer to leave the minimum at a frequency goes everywhere so 384Mhz
