I just bought a nexus one with the old resetting issue that seems to have come up a lot.
I've been stress testing the phone (using StabilityTest) and found that the sure way to get it to reset is to heat it up, by charging it, stress testing for a while (usually a few mins), putting it on a hot water bottle ect.
The temperature in these cases usually gets to around 30 C before it dies.
I put it on some frozen milk and sure enough its been stress testing for half an hour with no problems - the temperature sticks at about 15 C.
I'll try opening it up and cleaning everything I can with isopropanol. I figure maybe there's some gunk preventing proper cooling?
Any thoughts as to what else could be causing this?
Might be defective or degraded CPU.
Heat slows down electric signals, and the CPU is built to withstand a specific amount of heat without failures. If in the manufacturing process somewhere in the CPU there appears too small (physically) semiconductor or metal layer, it won't withstand the heat. Moreover, heating/cooling cycles destroy material slowly - and one of those layers could be marginal when manufactured, and pass the tests, and later get partially destroyed - and make the CPU prone to overheating.
Have you applied the 2.3.4 update?
This was supposedly a bug fixed in the 2.3.4 update...
Thanks for the replies.
Jack_R1 - sounds like a good theory, it's a shame theres no way (that i know) of checking whether the cpu is making errors like in prime95. I can stress test it but all I know is when it crashes. Presumably if the cpu is degraded it will be messing up alot.
Another theory I read about was that some phones where shipped with a fault in the main pcb that is supposed to reset the phone when it gets too hot as a protection measure.
GldRush98 - I will give it a go, I'm downloading the latest cm nightly which I presume is 2.3.4 - I had read that the reset fix was for nexus s phones though?
I've just treid undervolting the kernal, it might not fix it but it could be stable enough for most things. An undervolt of 75mv managed a stress test of 20mins which is a record without ice...
EDIT: StabilityTest does report errors. I just haven't been getting any, would this mean its not the cpu?
I think you're right, that fix was for the Nexus S.
Sorry bud
Same here.. It mainly starts after update the radio. If you check the last kmsg you'll see that it's the radio which crashed.
If I use my phone during charging, it resets all the time.
What I read is
* May be a hardware issue that HTC can fix (but my phone have more than one year so...)
* May be sim card issue. I'll change it tomorrow, will see.
I've never overclocked or overvolt my cell, mainly under clock to 960 and undervolt, so I reckon it's not our fault.

Its not a sim card issue for me.. Its been crashing without one in. Maybe worth disabling the radio and testing like that?
I just tried overvolting my cpu by 50mv and it seems rock solid. 1 hour 30 on stabilitytest without a crash and while charging. I'll keep testing and let you know. Might be worth a try if your willing to overvolt. Useful links here:

so, if i understood this correctly, and to solve my random reboot problem..i have to flash tiamat-kernel, and then PSM +50 Nexus One file????
i am running cm7 rom my n1 is unlocked.
That's what I did, but I've no idea why so no guarantees. Another point is that it probably won't stop reboots entirely.. I put my phone on a hot water bottle and left it stress testing - it rebooted.
Should make it pretty stable for normal use if you don't live in a desert though.
Let me know how you get on.
i just installed the tiamat kernel i am thinking of trying it out before flashing the psm file
Sounds good. Maybe the fix was the tiamat kernal not the overvolt...
I've spent half the day fixing my phone after I somehow destroyed it in testing - left it on the hot water bottle stress testing too long. It decided to reset and then get stuck on the boot screen no matter what I tried to reflash.
Just got it working again now, running cm7 and tiamat (without ov) to test...
the tiamat kernel alone didn't help...i flashed the psm+50 file..i will report back...
Yeah, didn't work for me either, I've also tried insectRavens kernal to test and no difference there. +50 still seems to be radically more stable for me.
Something I did notice is that the default smartass governor used by tiamat slows my phone down, I've changed it to interactive using setcpu which seems to be about normal speed. Might be worth doing...
Sorry to say this but psm file didn't help me either
That's a shame. Ah well, maybe something particularly weird is going on with my phone. Seems to be fixed anyway.
I changed my SIM card, with no effect. I'm using the last redstar kernel and found it more stable but when charging. It's quite better, but not as good as I would.. sadly.

SLCD Nexus one 35°C then... reboot or freeze some ideas
Hi to everyone.... very interesting thread. I'm an owner of 2 nexus one, AMOLED and SLCD the first one is perfect the SLCD have overheating issue it was bought second hand on ebay it's a vodafone espana.
I've noticed that it's working perfect till its working temperature become 35.6°C i.e. 96.08°F. It can freeze (need to remove battery) or it reboot but freeze on colored cross logo. As soon as I shutdown it removing battery and try to power, it vibrates 7 seven times.
Searching on the web seven times vibrating is CPU working bad for bad temperature. Anyone has tried to disassemble nexus one and putting thermal paste on Snapdragon to reduce overheating and better heating dissipation?
For sure for better stability we need to overvolt but we need to eliminate overheating maybe also modifying plastic on the back of the down side of nexus one.
When I bought it, it was winter so anykind of issue now I need to shutdown if overheating remove battery and wait some minutes.
Stability test apk it's not a problem I can use it for one hour and half without issue using tiamat kernel vipermod plus +50mvolt with setcpu on demand with maximum of 422-466-499mhz for cpu frequency.
The real test is running Angry Birds Rio try playing with it (with full frequency 998mhz without tiamat kernel and vipermod I can play only some level maybe 10-15mins) with this kind of configuration I succeed playing for one hour and half before first reboot.
So Angry Birds is the real test (hoping that it has anykind of bugs ) maybe that physics calculation are written bad or are alots and cpu overheat.
P.S.
Anyone opened it putting thermal paste?
P.P.S.
Sorry for my english I'm from Italy hope I have been clear.
P.P.P.S.
Sorry for long post.
Best Regards
Tony
I finally send it back to HTC, for reparation. Costs me 55$, and 2weeks after, my nexy came back.
Since, all work. HTC changed all the main board. The nexus can go through 100°F without any reboot. So maybe you can do that, but it seems to be much more overheating :-/

Had the same problem too....sometimes when the phone is hot, theres a delay between making calls and the phone actually dialling. For info i'm on standard kl3 rom rooted with cf kernel. Phone is on on demand gov standard speed 1.4ghz. Appreciate any help...thanks.
I'm running Abyss 2.3, 100 - 1400 with Smartass V2 Governor. And it works fantastic I must say. You might wanna try a new Kernel FM 1.5 or Abyss 2.3
It's normal for the CPU to warm up when you're playing games and anything causing the CPU to run at max for a long time.
Install CPU Spy from the market and make sure you're phone goes into deep sleep and monitor the other frequencies as well.
After installing new roms or kernels the phone usually gets warm as well. Just reboot and it should be okay after a couple of minutes. That's what I experienced on my Note
Mine is completely stock... Haven't even installed 3 apps yet. The phone is never in a case and the heat appears to originate from the camera area any thoughts or ideas or am I just over reacting?
Btw the phone doesn't slow down or act different operationally just gets warm lol
below 20% of battery power any device getting hot.
plus maybe you making hard time to processor
naw the phone is at 80 percent as well :/ i think im just over thinking lol the phone is operating like a champ just want to make sure its nothing serious
Mine gets pretty hot in same area wen playing games, its just the processor heating up, sure it for force close the app, if it couldn't handle it!
Yeah.. Any processor will get hot when running. Remember there's nothing to keep it cool! So I think if you put it on your cheek and it stings after a while there may be a problem. Otherwise it's pretty normal for the Note.

alright sounds good ill keep my eye on it thx for the fast responses
Everything I see in the market is pretty much battery temp apps instead. When playing games, like Minecraft for example, My CPU (im assuming) feels like it is trying to melt its way out of my phone. I need to find out what the danger temps are and a way for me to see what the current temperature is.
After a quick search, I am guessing that the Note does not have a CPU temp sensor, is this correct?
I am worried about overheating and don't want to damage my device. It only took 10 minutes or so the other night playing minecraft to get the phone extremely warm in my hand. Any suggestions? I even locked it down to one core to try and reduce the power it used.
use tegrak o think
If you have all stock then you have nothing to worry if it burns you get a replacement. If you flashed OC UV rooted usw. Then you can worry about it.

You can check the general device temperature with this.
Can anyone let me know the below temperatures for Xperia T CPU running stock rom is ok or not ok?
idle : upto 36C ish
on slight use : above 40C
on longer usage of basic apps such as whatsapp, viber, facebook: between 40 to 50C
browser: around 55C (browsing xda took it over 60C)
repost
CPU temperature is not so important, it will always be that "hot" while being on use. Battery temperature is the thing that should be important to you.
I think these values are ok, as long as your phone does not shutdown unexpectedely (with the aproppriate "Shutting down" mesaage box) - that usualy means that the temperature of both CPU and the battery is way too high and any other operations may result in their permanent damage. If you don't experience such situations then I think you shouldn't be worried about anything
Anyway I have to tell you that IMHO this phone has, in fact, some "problems" with overheating or at least with pretty high temperature than it should be normally. But I don't care, after two years of really heavy usage - it still works and it never disappointed me, I hope you won't be too
Thermal throttling will start at around 65-70C, at 80 the phone will shutdown.
These functions are hard coded in kernel, so dont worry.

Battery temperature hasn't gone beyond 40C if I remember. Only started to monitor recently. I've been using this just over two years too and never felt any heat when using it for normal usage on 4.0 and 4.1 stock roms.
Only felt it on 4.3 and downgrading after trying 4.3 uk rom 2nd time, even 4.1 now produces noticeable heat which is what's bugging me. Really regret for upgrading to 4.3 for a 2nd time :'(
The initial downgrade was done through SEUS as 4.3 wasn't released for UK then and had the blue triangle icon on some bootups but no other issue or heat.
Which rom do you use now on your device?
40C is really low value for the battery. Trust me, you really shouldn't be worried about the temperature
I was using the newest build of OmniROM until yesterday. I flashed the newest release of CM11 and I'm not disappointed.
ok, thanks. I am trying the Omega v2 rom since yesterday, but it seems to make it much warmer so might head back to 4.1

thanks, just installed the app. It seems to be 'ondemand' by default. :/
Just finished setting up 4.1 stock rom, and a little bit of usage heats it up very quickly. With the heat, battery level goes down very quickly too

Well it happens on my Xperia V too no matter what I do, but since I've been using a silicone case I don't notice it anymore and it doesn't burn my fingers like it used to. Maybe try changing governor to interactive...I'm using it now and the phone seems pretty cold

I've been using a TPU gel case since I bought the phone... and never felt any heat (apart from when trying out 4.3 but yet less than present level of heat). So seems it took 2 years for the phone to start this 'heating up' mode. I am trying to understand if it is a software issue or something to do with hardware.

I've read that almost all Sony phones heat up so it's probably a hardware issue...but since rooting and uninstalling all bloatware and disabling some of the google's services, I noticed my phone doesn't really heat up that much anymore.

Even I have rooted and disabled almost all the bloatware including some google apps (actually removed them from the system/app folder itself). This was how it was prior to 4.3 testing and had no issues. Only heated slightly for a YouTube video or so. Removed the same list of items this time around as well, but for even apps like whatsapp it heats..so something is definitely wrong... it remains cool on idle, hence not a background service that causes it.

that's exactly how mine was
wondering if there is some clash in the internal memory area.. (which happened when using flashtool to downgrade... from 4.3 this time). Before used SUS as 4.3 wasn't released for UK and it repaired to 4.1
When i play CoC with data mobile the temperature become very high...this can damage any hardware components?
Because i changed the battery two times for random reboots and i think that some components are broken
its WINTER

Hello guys,
Recently i had to send in my Z1 because I bricked it! Sony said various components were broken and replaced including the motherboard the phone works fine and better than before but i've noticed an increase in battery temperature! Before the repair my battery never went above 30°C but after the repair my battery is often over 40°C and I do not know what's wrong!
Is this normal or should I be worried?
after some browsing and writing this text: the cpu is 55°C and the battery is 44°C no overclocking is used and I am using the same rom as before the repair (crdroid)
Update: more browsing whilst charging cpu is 60°C and battery is 47°C charging was automatically stopped
What firmware version before the brick and what version after?

Don't know what it was before but my phone came back with 14.5.A.0.270
I'd suggest taking it to Sony service center
The heat depends on many factors such as the room tem (if is hot in the room the phone can't be cooler than the room temp) same story if you are using it outside. A few days ago it was about 40 degree celsius in my city and my z1 was hot even with little usage. Hope you get the idea. So if you use it in a hot room it is normal for the phone to heat.
I didn't read that you are using the same ROM as before sorry, so isn't a ROM problem but anyway I suggest try downgrade to stock KK if the problem persist send it to Sony service center

Those readings are abnormal. Your battery will fail in a few months and cpu will burn once the warranty expires. Go back to kitkat and check. If temperatures are within the norm, that's stock lp fault. Either stay with KK or use a custom rom.
I smell some cpu overuse here... Do you use task killers? If yes, they do more harm than good, because you kill services that your system will respawn within a few seconds (and use cpu to do that)
Also, a good check with an app such OS Monitor can tell you what is burning down your cpu cycles...
Don't forget to read the temps while idling, if there is no cpu use in idling and high temps (40+) unless you live in Sahara, send your device back to Sony or try to restock and do a clean install of your rom (sometimes this works for me)

It seems like the voltages on every kernel are totally NOT optimised for PVS3 as I can keep slashing 25mV off of the lower frequencies like 300mHz without the device shutting down, could cpu overvolting be the problem?

You are right.... Battery life decreases every day. Now it barely lasts 3 hours :/
Well I guess it just died... Was messing with my ROM and suddenly everything crashed and it never booted again... Not a single ROM works all stuck on a flickering boot animation! Recoveries are also a hot mess
