Undervolting Damage? - Xperia Play Q&A, Help & Troubleshooting

Can undervolting, in any way, make ure phone heat up more or loose more battery?
/==(CyberScopes)==\

I undervolted 50mV and my phone is still okay

Wats the best undervolting level?
/==(CyberScopes)==\

I don't think it will damege the hardware, but the software may not boot due to the CPU not having enough energy to process all the bits of data there for having to restore a nandroid or ftf. But I don't know about a safe voltege as I am on a stock kernel and locked bootloader

Doomlord said -100mv is stable for him. But I not dare so I go till -50mV

If i try undervolting, my battery life goes to hell.
Its different from phone to phone.

Ive got -100mv and i cant tell if its givin more or less batt.

Undervolting will never harm the phone, though it may prevent it from booting (if the undervolt is set on boot), or make the phone sporadically freeze/reboot. Some frequencies can undervolt more than others, and each phone's tolerance will vary as well. I've been able to go down -225mV on the 1024MHz frequency (or even -250mV on 1017MHz), though that's the farthest any of them has gone.

Yeah I've heard of overclocking causing damage, but never undervolting. It may cause some issues, but actual damage? I don't think so.

-Undervolting should GAIN BATTERY.
-Going too low might make your device freeze or not boot.
-Because of the way that you are actually taking away the energy this actually makes the phone slightly cooler.
- I myself don't like messing up with the voltages, there shouldn't be a very huge battery difference (Only about 1-6%) and I prefer stability.
-If you are still thinking of doing so then use a CPU stress app and test on every single step that you go down by for at least 20 minutes.

Anybody know any good undervoltages for 1.6ghz overclock? I need to overclock this high to get my games going.

I'm able to set 1.6GHz to 1200mV stable, but it varies from phone to phone. (1200mV is the same as stock 1GHz voltage btw )

is undervolting really necessary?

No as I earlier explained it only saves about 5% battery and heat.

That's what you want it to do, and that is the usual result of moderate undervolting, but that is not always the result.
The phone checks itself (similar to parity checks). Excessive undervolt can make the phone cpu do the same thing over and over until it comes out right

It could have happened because your phone has gone to the highest possible frequency, I'm not sure about it though.
How do I change the voltage in android without having to edit the kernel?

I agree that the safest level of undervolting is -50 or even -75 but anything beyond -100 would make the device restart when it hits the min clock speed.

Can somebody give me tutorial how to undervolting custom kernel? When using/try doomkernel n lupus still can't see a chance to uv. N i don't want to use setxperia.

(Q)I have a og evo and cant overclock it 1.2ghz.

I have a og evo I want to know why when I overclock to 1.2ghz it freezes my phone why does it do that ?
Sent from my Nocturnal 4G using xda premium
Each Evo is different. Some of them can't handle that high overclock, or can't be undervolted very low. Each one is different, each has its limits.
I don't understand the big deal with overclocking. It burns your battery faster. I personally underclock, with little to no lag and is good enough for my casual gaming needs
Mine doesn't like a clock much at all. I can get about 1.1 before it starts locking up but even then it hangs a lot. I honestly don't see a difference from 1.0 to 1.2. Get a decent rom, good kernel and try out the v6 script an I almost guarantee you will like that better.

Well for us to be able to help you, you would need to provide us with more details on how you are trying to accomplish this.
I use no frils cpu but have also tried setcpu and viperMOD I know that's the best way to overclock but is very confusing. Have any step by step instructions to of to 1.2 I know having higher voltages helps as well.

Overclocking is overrated. If you need to overclock for every day usage, then something is wrong - at least in my opinion. Resource intensive gaming is different, but you shouldn't need to overclock for browsing, texting, casual games, etc.
Try out the V6 Supercharger script. I'm not currently using it, but have in the past and it seemed to make my phone more snappy. A lot of people swear by it and it's a great script, definitely worth a shot. There are other things you can do to speed up your phone without overclocking. I'd try other options first since overclocking will chew through your battery. Increase the dalvik vm heap size, there are plenty of free apps on the market to help with this task. Uninstall apps you don't use, I'll bet that you never use some of the apps on your phone. Back them up with Titanium Backup and you can restore them if you ever need them again.
In case you didn't already know, the Evo can't overclock past 1.2, I'm not 100% sure why - it has something to do with the processor.

I never oc over 1075 and only when plugged in if i play a game I need to oc.for I just activate my charging profile and plug up and play 1.2 ghz is a good chance of doing serious.damage as these older scorpion processors get very very hot at that clock speed so they lock up to try and protect themselves from heat damage or they shut down the phone 1075 is as high as you should need to go for any games the evo can handle on the subpar gpu

I'm pretty sure viperMOD is more for undervolting than overclocking, which are not suppose to be combined together. I am running vipermod with max voltages - 50. Other nite was playing snes9x and was getting some lag with a game so I bumped max CPU up to 1.2. Phone went into a bootloop and had to superwipe and reflash everything. Don't know if its b/c vipermod + 1.2 CPU or just bumping up CPU. Didn't try it again.

You can overclock and undervolt together just fine. You just need to ensure that every frequency has a high enough voltage to run the processor at that step. My Evo is overclocked and undervolted just fine, although IIRC I can only push it up to 1.1 GHz . My tablet is 1ghz to 1.6ghz and is undervolted as well, though.
merge rls 2.0, iron monkey, Droid overclock because of the profiles options. I set up four profiles including one for temp. sometimes i'm underclocking and sometimes overclocking but only up to 1.19 to prevent freeze and boot loops. Only downside is right at open Droid overclock needs su permission but that is my choice since profile changes at open.
Very snappy afterwards.

When I had the 4G, I was never able to go above 1118, or somewhere around that. It would have freezing issues.
On my evo shift, I was able to do 1.7 gHz (compared to stock 800 mhz) ok. 1.6 pretty reliabily, and I could run 1.5 all day long. Some guys could do 1.9. It just depends on the phone.
Actually overclocking and undervolting is counter-productive. What you should do, is read carhaulers and ropodopes guide over at vaelepak. Its give some good useful info about how to set up a good aosp rom. I'm underclocked, undervolted, and still getting 1400+ benchmarks. Check it out bro. You'll love the results.

What? Overclocking and undervolting are two completely different things, and they aren't mutually exclusive. Unless you can provide a good reason as to why it's counter productive to do both, I don't buy that at all. Just checked my phone, my overclock requires an extra 25 mV for all three steps I've overclocked. 25mV isnt much, and it certainly isn't going to kill my battery that much faster.
Besides, the only time the CPU is going to be entering these high power modes is when it needs to do work, and it's better to do work as fast as possible to go back to sleep. Would you rather wake up, do a mundane task for 5 minutes, then go back to sleep or wake up, do a task at 2x the speed while only consuming 30-50% more energy, then going back to sleep after only 2.5 minutes?

First let me say I don't use viper mod or any voltage controlling mod.
On sense 3.0 roms such as mikg I over clock to 1152 and set the minimum to 384 and its smooth as butter. No problem and battery lasts all day.
On aosp however such as decks (I'm on it now) I underclock to 499 and leave the min at 254. Smooth as always and battery lasts forever.
Anything past 1152 is going to cause problems (at least in my experience) also the rom/kernel can effect how much you can overclock.

Its counter productive because it is giving less to something that needs more. (Don't take this post as me trying to be a ****. Just voicing how someone explained it to me a while ago)
Think of this as cars.
Lets say you have a nice fancy v8 mustang. Stock, everything is well, balanced.
If you start adding parts and get it pushing out 1000 horsepower (overclock) your most likely gonna need more feul (voltage) or at least stock amount flowing into the engine just to keep it running.
Now lets say you got that same 1000 horsepower gas destroying mustang and you start to lower the amount of gas flowing into the engine (undervolt (done in vipermod)) cylinders (CPU) wont get enough gas, it wont work, and your stuck going no where.
So if that made sense (did to me) then you can see why they are counter productive. Unless your using vipermod to overvolt (which idk if you can since I don't use it) then you can disregard this whole post

Your car analogy is completely irrelevant. You can look up the exact voltages that the CPU runs on at every frequency, *even when overclocking*. Overclocking an Evo 1ghz to 1.2ghz takes maybe a 5% bump in voltage, and that 5% extra power is only going to be used *when the CPU is running at max speed* (which is only when there is a lot of work to do), and even then, it's *still better to let the CPU run at max speed with a tiny bit more power consumption than to cap the CPU at a slower speed and make it work for even longer*. Intel calls it HUGI, Hurry Up and Get Idle.
I know what I'm talking about, and I wish people would stop trying to argue with me based off of second hand speculation. I do this for a living, after all. There is absolutely nothing wrong with overclocking and undervolting, and it's the best way to get the most battery life *and* performance out of your phone, period.

Hmm, *interesting*. I believe the best answer to the OP was covered rather well earlier. It's all about your rom/kernel/hardware combination. With all the variables to consider as relevant, your best bet is to experiment and find what works for your device. Don't check set on boot untill you are confident the set-up is stable. Higher is not always better with overclocking. My device runs blazingly well underclocked @768max. Gets insanely great battery @499max. However my quadrants are better @ 1036 than at 1190.
Great thing about android is you can experiment and learn through trial and error.

Overheating

I've OC 1,8 GHz... I know that when playing games, phone's temperature raises, but when I'm playing NFS HP it almost burns me. What can I do with that? Does custom ROM may reduce the overheating?
And which ROM is the best?
reduce your overclock to 1.4ghz...really no need to go above 1.4ghz currently
yeah, but with 1,8 GHz is the best score in Antutu...
So in the end its just about benchmark score..

I'm running the Titanium Kernel build#4 and occasionally take it up to 1.7GHz; the handset does get extremely hot (battery temps were somewhere in the range of 50C-60C, I think) so I never OC that high anymore. It probably cant be very good for it
As for "best" ROMs, it really does depend on what you prefer, but flashing the Titanium Kernel and running the Lionheart governor seems to give the best performance and battery life at a 1.4GHz OC, for me anyways.

That is true. The CPU can withstand ~100°C but not your hand. Standard phones has plastick fascia, so you are not sensing the heat that much as in our aluminium V. The phone can withstand that much, the question is how long...
As for me, I use the phone at stock 1Ghz, and for me it is more than enough.

[Q] R800x, Post your Overclock CPU speeds below....

OK, so I currently have my PLAY set to 1.2ghz. My first android phone I OCd from 600mhz to 1ghz and one day while playing a game I heard a loud pop noise, then my phone shut off and that was that... toast. So I have been extremely leary of overclocking now. I am aware there are users who have OCd their phone to 1.4+
My question is how safe is when I use No frills to OC is it ramping up the volts to get that extra power. Also according to the Snapdragon layout it lists the S2 in our phones as capable of 1-1.5ghz... does this mean I could technically go up to 1.5 and be OK? I have a large 3600mha mugen battery, so thats not an issue, but what I am afraid of is popping my phones brains out...

We're on the MSM8655 instead of the 8225. iirc, the difference is that it's cdma oriented as opposed to gsm
Each chip is different in what it can handle, so your best bet is to test it out, slowly. When your system starts to act funky, step down the voltage/speed levels.

Ps. Tried running mine @ 2 ghz once and was promptly rewarded with a random reboot. It takes some time, but with mine I've figured out our can run 1.6 with no issues (I tend to keep it at to stock levels because my battery sucks )

K, thank you Pax for the feedback.
Just thought I would open this to everyone on R800x, interested if people could point there OC status below.
Mine is still on 1.2ghz. with Performance and BFQ
Highest I can go is 1.6, but I keep it around stock or slightly underclocked, with SetCPU profiles that increase to 1.2 for games and internet apps. smartassv2 and sio for governor and scheduler.
I heard that underclocking can end up reducing battery life over time. Is there truth to this or is it just a myth?

Undervolting CPU - More battery...

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 )

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 )

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
This thread will tell u everything it even has a gragh on wot chips can do what

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.
Is it true you guys aren't seeing ill effects on your battery by overclocking like that?

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.

2ghz.... the phone is old now. Make it bleed.

Don't try to Cross above 1600.
