[Q] Is it really safe to keep overclocking to 1GHz?

I am new to android phones. And i have no experience about overclock.
Will my cpu easily break down due to keep overclocking?..
Honestly, i seldom change my cell phone model, i want my defy can stay a life at least 1.5yr.

i think overclocking can't really damage your phone, voltage can. so i suggest you keep the voltage around [email protected] (default is [email protected], so this should be fine), and if the phone doesn't hang or reboot, you're good to go but you could try lowering vsels, you know, the lower the voltage, the lower the power consumption, the heat and the chance to fry your cpu but i'm not sure!

Yep, 1 GHz is safe, I'm using [email protected] as well, and the CPU is capable to run easily at [email protected] continuously. The leaked Gingerbread ROM from Motorola uses 1GHz as well, so don't worry, you just have to find the safe vsel settings.

thanks for replying, i m currently using 1GHz @ 58 .. Everything is alright
Should I make the voltage as low as possible?

yeah, just to lower the power consumption and temperature, but it isn't necessary.

Can you share your voltage setting please..?
I do the stability test and it gets successful run for 5min then this means the setting is okay?

i don't overclock, just undervolt, here are my settings (with setvsel):
800MHz - 45vsel
600MHz - 30vsel
300MHz - 18vsel
up_threshold: 90%
actually if you wanna make absolutely sure your device is stable, you should run it like for an hour. but if it runs for 5 minutes without error that's quite okay, you shouldn't have problems with those settings

Thanks so much, i m trying to lower my voltage setting.
Besides, i want to ask about the battery temperature, what is the maximum temperature before getting damage to the cell? I usually goes up to 37~39 degree celsius.. is it normal?

mine is usually around 29-32 °C, but i have it undervolted, so idk. but 37-39 seems a bit high, that means the cpu temp is way over 40 degrees, you should check it out!
EDIT: tried stress testing for 20 minutes with [email protected], it went up to 35°C, so you should definitely find out what's wrong with your device!

I actually underclocked to 600MHz, since I couldn't see a big difference even at 1200MHz in normal usage. A Pentium3 at 4Ghz will still not perform as well as a slower clocked new CPU for example, CPU design is more important - what instructions it supports.
Battery life is more imprtant to me and heat is very bad for Li-ion batteries too.
Also I found changing the CPU governor to "interactive" made a difference in GUI responsiveness and I have had less stuttering.

so, what's your standby lifetime after underclocked cpu?

I can see the performance improved when i was watching flash video on browser. But honestly, i dont think there are anymore huge difference after overclocking..
But as the battery life still remains quite well, i will still keep overclocking to 1GHz.. Isn't it a good idea?

lol... What happend to HD and THD games... Did u try playing them at 600mhz??

Overclocking to 1 GHz with the right voltage values seems to be absolutely no problem for Defy.
BTW, does anyone know whether it's possible to set scaling governor to "Interactive" mode under Froyo? Gingerbread kernel let me set it, but I haven't found the way under Froyo.

Battery life was a little bit better, the display and 3G always draw a lot of power.
Standby time got better, but I don't use very low vsel any more due to errors in YouTube and dropped connection of radio streams.
Before I used 300-600-800 at 20-30-48, this was very stable in stability test, but for example Youtube would start showing "error playing video". After I increased vsel, it went away.
I mostly did it to lower temperature, optimal temperature for li-ion is around 25°C according to Wikipedia I think.
I don't play 3d games, they would benefit the most from overclock I believe.
Angry birds RIO for example would stutter for a second or two after a level loaded, but it would become as smooth as at higher clocks, when I wait for a second.
I hope flash gets better, when hardware acceleration gets enabled in Quarx's CM7.

I was running [email protected] for a month straight. No issues at all. The highest my temp reached was 112F after playing games for about an hour straight. I now just run it at [email protected], and it's plenty fast for me. I did some "testing" with all the options in SetVsel. It's not science sound, but if you use the Gingerbread Icon in the notification bar, and are running at stock (800 speed) you will notice when the CPU maxes out it doesn't even reach full capacity. I found Words with Friends to really use the CPU, and at 800 it pings the meter in the orange (The notification icon shows green, orange, and red for "zones"). If I overclock it at 1000 or above then the meter goes into the red. I don't know the exact number it switches from orange to red, but being at stock 800 is well below what the chip can really do since it doesn't even max out the meter. I hope I didn't confuse anyone. It makes sense to me.

weird...my cpu at any game reach the 800mhz
yet even in normal situations like browsing through the files on the phone it reaches 800mhz
and also despite the values i use in setvsel are not high(which is:
24 @ 300
34 @ 600
48 @ 800
)
the phone still reaches maximum 38C when i play games and if i set the value in the third vsel the games starts to hang!!
seems like i am the only one who have these problems..but why
anyone have any idea
im running stock arabic froyo btw
if someone can confirm to me that i can keep Arabic language if i installed another rom using custom restore in nandroid then i would be using prays or official 2.3 but no one answered me about that
anyway the important thing is anyone knows why my cpu temp is always high?

Well ambient temperature is important too. If it is 30°C where you live and your phone's temperature is at 35°C I'd say you are good. If the outside temperature is 10°C and your phone is dat 40°C I'd say there is something wrong (unless you were playing games or watching a movie).

in my opinion, it is definitely safe that you overclocking to the leaked moto level.
however, the voltage is still a mystery.
there's no constant conclusion about this.
i'm using [email protected], [email protected], [email protected], and it works fine for me

I'm getting really annoyed. No problems clocking up to 1100mhz with stock voltage (58). But changing the voltage settings, even slightly, makes the phone more or less unstable.

Super hot battery

Okay so I was busy playing Osmos HD (Awesome Game) and my phone started freaking out. I got a notification, Telling me that my phone was over 60°C and was going to power off until the device was cool enough so that no permanent damage is done. When I turned the device back on I noticed that I had a few twitchy pixels that were flashing like the notification led only more eradicate, Over the area where the main heat source was. Its been 2 hours now and my battery temp is at 49.1°C. And the device is finally stable enough to use, Although I still have the group of twitchy pixels.
I am outraged at the fact that whilst playing a game (Not whilst being charged) that the phone can get this hot, I mean can't HTC find a way to dissipate the heat better so that the phone doesn't fizzle and burn itself out thanks to the main feature of it (Tegra 3). I'm going to wait and see weather the GS3 is any good, But until then I'm going to put some aluminum tape on the inside of a case so that the device can dissipate heat better, the aluminum acting somewhat like a heat sink.

Now I don't know weather the temperature is accurate on the CPU but f**k me sideways that's not right!

Doesn't surprise me atall mate, mine has been doing the same since the day I bought it, right ****ing disappointment this phone, wish I waited for the SGS3.

I suspect you may be having the same issue I did. The gmail app has a bug in it which can lead the background sync service to sit chewing on CPU, if you use gmail try to disable sync and stop using the app (you can 'Disable' it too), use HTC mail instead.

There's your problem: "Performance" governor.
It will run your phone at full speed all the time. Switch it to "On Demand" or "Interactive" to give your phone a break.
It's up to you.

mine also heating
My cell also got heated ALOT once

oh boy
OK All HTC One X Tegra 3 Owners should understand that Tegra 3 is a variable SMP architecture
Meaning: The chip is meant to scale up and down and into the maximum of its thermal limits and out, this is the direction NV is taking and you can see it in their latest Kepler GPUS
which means never ever lock the clocks!
You have chosen Performance governor which locks it at a minimum of 1.4ghz what is worse is that in that mode, 2 cores are even disabled so you are actually loosing performance and not gaining!
run glowball in performance governor and watch how the frame rate hits bottom
Modes:
1.5ghz = single core
1.4ghz = dual/three cores
1.2ghz = quad cores
Governors
OnDemand = can use all the cores and all the steps, conservative and power efficient
Interactive = uses all the cores and all the steps but stays in top speeds more often
Performance = locks it to 2 cores @ 1.4ghz
and finally the GPU can run up to 533mhz depending on the CPU clock, this is a very high range for a 40nm chip and hence it needs to ramps down when its not needed to cool down!
You bought Tegra3 knowing its a quad 40nm SOC, this the thermal envelope of this SOC no surprises here!
To add some perspective to your drama, use an iPad3 for few minutes and you will understand quad CPU or GPU in a mobile device this season = heat = ITS OK
I dont understand why all the nagging when both HTC and Apple said these are normal operational temps during heavy use

Oh boy, you're a god. HTC should hire you. Google too. And Apple.

Does the OnePlus 3 get extremely hot to the touch?

Everywhere I looked they said that the OnePlus 3 has the least thermal throttling and best sustained performance of any phone out there. But nobody discussed why exactly it did not throttle while other phones did. Everyone simply said "Oh they must have very good thermal management or something". Then I saw a video comparing the temperatures of the ZTE axon 7 and the OnePlus 3 (google "Zte axon 7 vs OnePlus 3 antutu thermal throttling"), it turns out the reason the OnePlus 3 doesn't throttle isn't some magical thermal dissipation and management, it's solely because they raised the temperature at which the phone would throttle to beyond comfortable zones. In the video with just a few iterations of Antutu CPU test, the OnePlus 3 metal skin's temperature reached a scorching 47 degrees Celcius. Google shows that holding anything metal at 50 degrees Celcius for more than a brief moment can cause tissue damage (1st degree burns). And this phone was just shy of that temperature during Antutu's benchmarks when only the CPU was running, so can you imagine what temperatures it would reach when you're playing a highly graphical game where both CPU and GPU are being taxed at the same time? Why does nobody talk about this?

nothing to worry about IMO

Thank you for your useless opinion friend.

The only game i play on the one plus it's hearthstone but I don't notice an high temperature during session ... I think a benchmark it's one of the most stressful things you can do with your smartphone...

No actually Hearthstone is not a demanding game at all, not even remotely. In fact an iphone 4 could run it without busting a sweat. And many games can actually be more stressful than a benchmark because you would be running both CPU and GPU at the same time and would likely be running the GPU at 100%. Most GPU benchmarks run the GPU at 100% too but without using the CPU at the same time.

A non issue imo

I can't figure out why the hell that idiot in the video used real racing as a benchmark. Do these people even know what a GPU or CPU is?
Anyway, that video is not reliable, especially since the OnePlus 3 uses a 1080p display and has to push far less pixels than those other phones, that game does not tax the phone's hardware in any way shape or form.

The CPU starts throttling at 75°C like pretty much any other phone out there... This thing just dissipates heat better than any other Android phone out there which is why the chassis heats up a bit more. Don't worry it doesn't get that hot at all

The fact that there's a lot of us out here using the phone, but as far as I've seen zero reports of people getting burnt by hot phones, in. Y experience it stays way cooler to the touch than either of my last two phones (Xperia z2 and Samsung s3).

Normal temperature range for OP3

What are the normal temperature for oneplus 3, when playing games, using fb,messsenger,whatsapp in 4g and watching video and doing all the same activities in an ambent temperature of 29

I don't think many people actually measure temps of their phones ... Suffice to say - it can get pretty warm, but not too hot (maybe max around 45°C on surface). Internal (cpu) I guess could easily achieve 70+.
P.S.: Stop being so paranoid! This is at least third thread you opened about temperatures and people keep telling you that your phone is NOT overheating ...

This is the reason
I posted a pic using cpu Z... It was when I was uploading a video in Instagram.... See sensors Reaching 50-55???
I was tethering and using Instagram.. Is this normal for this

With light usage i get about 30°c and on heavy load the cpu goes up to 70°c, those temps are pretty normal

FFS it's a metal backed device which conducts heat but also passively cools faster. Devices are getting very powerful. I came from a Z3+ which hit 80-90 °c on the soc. This device is no where near being "hot" and that's from running consistent synthetic benchmarks and gets to 50°c but cooled very fast.
If it hits 80°c + on the Soc not the individual cores as they ramp up and down very fast then maybe you can repost.

Holy crap I'm tired of this... Those sensors are for the CPU, the CPU throttles at 85°C and here you are asking us the same question in which we've already answered you.. THERE IS NO PROBLEM with your phone. Now stop asking these questions and stop being so freakin paranoid. It's hot outside your phone will get hot.

CPU Thottling?

Does the Samsung Galaxy Note10+ (Snapdragon) throttle the CPU to save battery life or manage heat? If so, is there some way to modify that?

Of course there would be a way of doing it, but first root must be achieved

i believe so i keep it on high performance mode at all times

I've only seen this happen if you have either of the power saving moves enabled.

I ran a test with the device set to high performance mode, and there is definitely some modest throttling after the 2 minute mark. Root can't come soon enough.

Here are the results of a more intensive test: https://imgur.com/a/3t4o6f3

So you want it to overheat instead of slow down? Damn thing says 174 degrees.

Can someone, who has the Exynos version, do the CPU Throttling Test and share the picture, please?

The only rootless setting you can set for it is the moderate power save that fix it to 70%
You need root otherwise.

Every CPU have Throttling. This is about temp. increasing. Have one test in GSMARENA.COM
Flagships vs Gaming phones. After 1 hour hard gaming casual flagships decreasing CPU power on 60, 70 % to prevent overheating. In Gamer phones like ROG or Black Shark decreasing is only around 90%. This is because they have active cooling systems.

I agree. But not only gaming devices. For example, Sony Xperia XZ Premium doesn't throttle that much.
I just wanted to see if there is a difference in Throttle on Exynos and Snapdragon.
If someone could do a CPU Throttling Test on Exynos, I would be very happy!

Exynos is horrendous. Just look at gips. Im starting to believe more and more there's something wrong with my device.
