So I was wondering what temps you guys are seeing when your phone overheats.
My phone reboots when it hits 37 C, which seems awful low. Anyone else seeing such low reboot temps?

Mine doesn't reboot that low, the highest I have seen it go was like 43.7 or something
I've never had my phone reboot due to overheating even at 42°C. Running CM6.01

Hmm, this is getting frustrating. I've begun to reboot at around 37 C. Is there any way to change that number? Anything to reset?
Is that CPU or battery temperature? If battery then the CPU would be much hotter.

Battery... but it's weird. The battery temperature gets to 37 C, and then reboot. When I very distinctly remember it before going 45+ C without a problem.
And now I'm bootlooping. Seems to start up, and is still too hot, then reboots again. Anyone have this happen to them? Lower temp reboots?
Sounds like you may have permanently damaged your device, if your battery temp were 40+ degree celsius your CPU temp would be a sustained 15+ degrees hotter. Running your device this hot often certainly could damage it over time.

Try a standard or increasing voltage kernel if possible.

No no, my battery isn't that hot for long amounts of time, just, like when I'm surfing for a long time or something. Trying an undervolted kernel now.
Do you have a backup battery that you can try - see if you get the same results? Batteries do occassionally stop working properly.
My phone would reboot when using GPS in the car if it was on the dashboard or mounted - I checked the temperature when it booted and didn't get stuck in a boot loop and it was around 45c.....
I returned the phone to stock and brought it back to vzw, they gave me a new battery, phone still runs somewhat hot even stock.

But mine is rebooting at 37-38 C. Which is awfully low. I'm RUU'd, S-oned, and factory-resetted and STILL it happens. So it's a hardware problem.
Gonna take it into a Verizon store and demand a replacement on the spot x]
I can advisr from personal experience on your symptoms that you have one choice ... Return to verizon for a refurb. This is what happens when you have an early incredible with a faulty hardware radio. It gets to the point where it starts trying to compensate and super heats. You must return.
Every other suggestion would be a mask to an existing well known hardware problem.
I once left my phone in a black bag on a hot summer day. It went up to 50 C with no problems. It didn't reboot or anything.
I have one of the original Incredible's from launch day, it is usually around 43-45. Sometimes it gets warmer than that playing games. Never actually had any problems. The hottest it ever gets is on Z rom's. Those things have gotten it to 50 .
I'm on CM7 W/Slayher's 2.6.37 kernel, and it's at 42 just on the home screen. Mind you this is all on stock speeds. My phone doesn't like to overclock. Regardless of kernel. It can go to 1.113 sometimes, but any more = reboot.
On the HTC Incredible site, there is a FAQ which states the maximum recommended operating temp is ~60C.
I'm relatively sure there is no problem with the battery or the CPU doing up to ~90 for awhile because that's a fairly common temp for CPUs and Batteries to withstand. I'm sure that like most batteries , at >~50C it is less efficient, but I doubt the CPU is presented with any problems in that range.
Phones present a unique set of high-temp problems. Cooling sucks in those little enclosed boxes, and manufacturers definitely don't want your hand or ear burned, and are terrified of having a battery burn up in your hand or pocket, so that is probably why 60 is said to be max. I don't like picking up my phone when it's at all hot (~40C or more) but while experimenting with my own kernels and voltages and overclocking, I've had it reboot somewhere around 60C. Was it the temp, or was it overclocked too far? I have no idea, but I lowered both and stopped taking stupid chances with it.
This thing of rebooting at 37C seems nuts, inappropriate, and most likely a defective part, or one of the many services or apps that perhaps does the wrong thing (accesses verbotten memory, bad ptr, etc..)
A bad example for sure, but at work, many of our HP or Dell Racked servers (DL380's etc), are too hot to touch while running. They have enough fans to power a 747, and it just makes it pretty clear that in some cases, processors and other components can run at amazing temps.

Often while playing a game, my screen will randomly dim and i will check the brightness option where it warns me of overheating.
The battery temp is only 42C, and the phone isnt very warm, ive felt phones get way hotter.
Whats wrong? is it the phone? or normal? Anything I can do?
Is ur phone overclocked? Playing game does makes the phone really hot even without OC ur cpu.

I'm not speaking for everyone certainly but I have seen 42c while talking on the phone.
It does get a bit warm, but I never get the warning you are speaking of. I am completely stock.
I now haven't gotten to this temperature (close but not as high as 42c) in awhile.
My brightness always dims and gets limited to prevent overheating. My phone has gotten up to 125F while it was charging and I was using it (nothing very intensive though, like playing games or anything like that. Mostly texting, email, XDA) I have even had an overheating warning on the charging animation while ordnance few times too. I'm actually going to bring it in for them to look at. I'm stock kernel and rom(just rooted)
Just in a few minutes my screen has been on it just shot from 89.9F to 98F. And all I did was write this post.

125F is way too high, there's got to be something wrong with the phone. Mine sits at idle around 70F, with heavy use, it never reaches 100F. And I'm overclocked to 1.4GHZ.

Agreed. High 70s to mid 80s no matter what I do in a hot and humid hawaii climate. Reached 107 at 1.6ghz while plugged in doing 15 back to back benches to test for stability. Somethinf wrong with your phine sir
***CRITICAL MASS! ITS GUNNA BLOW!*** hahahaha
It happens only when im playing a game, also at Max brightness. Went up to about 44C. Not overclocked, but undervolted.
Is this abnormal? Should I try to get a replacement?
My GS1 got hotter than this and never gave me problems

my phone also dims
used to get temps around 115F on my evo 3D,never saw any ill effects though
this samsung does get to 102F or so occasionally,and no ill effects so far either

Well I undervolted, which doesnt make it run hotter, it'll make it cooler if anything.
I've never understood the logic behind that. A processer uses a certain amount of power, measured in Watts. Watts equals current times voltage. If you lower voltage, current has to increase, and more current equals more heat. Am I missing something?
im now using a custom rom with the overclock kernel... i set my phone to "1.4ghz" with AnTuTu... its working great now... no more fps lags on the games i play... and no crashes... im just curious about one thing? will it break the phone in any way? its not heating up or anything atm... i mean i have experienced phone heat on my sensation xe... that phone gets really hot STOCK....
i dont want to break my play... i really like it compared to other phones in the market right now(the only one with gamepads)... its my first time ocing a phone btw...
If its not noticably hot (the battery too) constantly then your fine, just bare in mind try not to push it past 1.6ghz i found my phone didnt last very long at that speed.
The only thing with oc its that it shortens the life of your cpu obviously depending on how much you oc it....and it drains more battery but its not that big of a deal

what do you mean by it didnt last very long? did it break the phone?
Basically, my phone is overclocked to 2.0 GHz with smartass scaling with max 800MHz interactive scaling when screen turned off. It works great! Lasts 2~3 days without gaming (5 to 7 days with airplane mode on) and 4~8 hours of hardcore gaming with full charge (6~12 with airplane mode on). I recommend using an extended battery (I haven't, yet) if you are doing so. And it also involves luck. Even if it is the same model, color, etc. some CPUs are more capable than others.
still testing my phone under 1.4ghz seems stable...

is it normal for the phone to be abit hotter than when it was running stock???
btw how does smartass compare to ondemand?? smartass tends to get lower benchmark scores than on demand

Yes ofc its normal - as each CPU/GPU creates heat based on the load it takes....
So the higher u OC the hotter it gets - thats why in former days OC was quite dangerous
In todays times cpu normaly 1st get unstable, and then has a safety function to shutdown if it gets too hot. (no warrenty that its the same for all chips)
smartass doesnt switch frequencies at once like on demand (e.g. instant from 200mhz to 1000mhz) but it tries to predict the needed power somehow so the whole switching is done in more steps... (as far as I remember)
So yes its performace is a bit below the on demand - but should not be that noticable - but it will also save your battery.
hey guys is it normal that our W heats up to about i think 45-50 degrees while charging.. sometimes it heats up too when using the internet via reverse tethering.. just wanna know if its normal, and some advices to prevent it would be awesome.
With Black Notes Hybrid 2nd Gen
Its happening to me aswell getting really hot.
I recently flashed to BlackNotes Rom and when i was charging it overnight for the first time,when i woke up i picked up my phone i immediatly dropped it.
i checked on set cpu the speed was min122 max 1401 ondemand.
ALSO i checked the temp it WAS 60c literally i swear phones should never go over 50c.On stock rom the highest i was every on was 45c playing games.
From then my phone always gets hot with 1401mhz. i dont know why.
With normal use average temp 31c-35c it used to be 27c stock ROM.
I think i sholud get a new battery because 60c is rediculous that could explode it and i thought li-ion batterys have fail safe or something like that for 50c???
EDIT: setCpu 122min 768max and my battery is still 36c im not playing any games im just on homescreen.

WOW. WOW. 60c is too far hot! and yes your phone and motherboard can be burned! When I using BN chapter 2, and when playing games (1401 mhz) the temperature never above 42c, and then I limit the cpu, it will automatically set the cpu speed 245-368 with powersave governor, and screenoff with the same configuration. so when idle, my phone never above 25c (im using arco CM9 now). and I suggesting you to buy a new battery
my phone heat up too,but about 40C only
I've been on the Bionic cow rom for the last few days with data enabled, anyway went to send 4 1.1mb pictures to another email address today and as well as taking around 10-15 mins (2G) it got really got like through my trousers it was making my leg quite hot but never seem'd to get that on original rom
Jamie.
just an addition to my post. i live in the philippines where the temperature is getting really hot this few days. i tried to charge my phone on the office where its about a bit cold and the phone never heated up. are you guys from a cold place and still heats up? if thats the case then my problem is just normal.
maybe you can try download cpu spy from play store and check your cpu time in state. now i'm using bionic cow rom with xxlm8 kernel, the cpu time in state is always 1401 mhz. it's fast but create heat when playing games n surfing!!! i've attach my device screen shot as reference.

sure ill try that app.. my phone heats up too now when im surving using droidvpn.
i found an app that displays the current temperature but only for the battery, i dunno if only the battery heats up and not the phone.. the attached screenshot was the normal temperature of my phone, ill try to upload another once i got time for hard gaming or browsing that can heat up the phone, maybe on weekend.
My phone usually goes up till 4OC. But thats when I use data network and watching movies on the web at the same time. When charging my phone heats up to 35C. Other than that I cant think of any other ways how my phone heats up. But will let you guys know when something comes up.

does your phone heats up while your using it? or just on charging? mine only heats up while charging so i only charge on the office to maintain the temperature, its better to charge on cold places, however if your phone heats up while you are using it then maybe its because of some tweaking that you've done to your phone thats makes it use too much CPU that causes the heat.
normally i play some hd games mostly bcz of games my phones heat up.does it happen to anyone too while playing games phone heat up.if i overclock my cpu and reduce the frequency @ 1.2 or 1.0 mhz i think then my phone heat less

i also play HD games and watch movies, but my phone only heats up when im using reverse tethering(means i use internet on my phone via usb from PC internet) and i think it will really cause heat because of internet and the same time charging while connected in the USB, maybe you made some more adjustments that made your phone heat easily. but if you play for hours then its normal, just for me don't play that much long or less your internal chips will melt.
Gello guys,
(I'm on MooDed ICS 1.0.2)
I wanted to know what kernel(s) is (are) the best to overclock the Arc and to what frequency can I go with the phone stable? I'm actually on InFamous Kernel ( http://forum.xda-developers.com/showthread.php?t=1843532 ) But I'm not overclock. I was before on DooM Kernel and overclock to 1.2 gh/z.
Thanks a lot! (And sorry for my bad English, I do my best)
It all depends on your phone. Even though there all made the same, some of the processors can not handle the same amount of OC as other do. The way to test which runs most stable is to slowly up the frequency every hour or so, and test it to see if it's stable.
If your phone starts to random reboot, then it's probably best that you choose the lower frequency to what you are using when it reboots.
I'm using inFamous Kernel too, its overclocked to 1.5.
1.4 should be theoretically safe as that the speed that the Arc S runs at with the same processor
EDIT: I don't recommend passing 1.5 on the Arc as it will very quickly burn out the processor. (Even at 1.5, it's running 50% more than what it was originally designed for).
Overclocking will also reduce your battery life. So it's swings and roundabouts depending on if you want performance or battery life.
Hope I helped
Over cloking is realy affect to battery life and all so the head will get increase,
am always usting 1.2Hz.i think it is enough to have a smoooth run for a xperia smart phone while saving the battery and reducing the risk
Ok thanks guys! I'll try all I can. I'm now overclocked to 1.2 ghz and battery life is good for me, because I recharge it all night. At 1.4 ghz, it's stable normally but the CPU is hot (very hot) and I don't want to burn it. But is it normal? Because Arc S is on this frequency and isn't normally so hot
So Thanks one more time!
Yeah, don't worry about it getting warm. If it gets really hot, then I'd recommend to stop using it for a while. Simply to let it cool down.
Mine can get to the point when it feels it's going to melt the plastic on the back yet it still works perfectly, so yeah i'd say its normal. There's also a ton of older threads about how much peoples arc's heat up when it's being used.
The reason why the processor gets so hot is because there is very little heat sink because of how thin the arc is.
Obviously the more you overclock the hotter the processor will get. The hotter the processor gets, the more quickly the CPU will burn out. If you don't like to replace your phone every few years, don't overclock it to the limit.
You should OC stable at 1.2 - 1.4 GHZ
Ah ok thanks.. I like to change it every year / 2 years. And now I'll try Puissant phone like GS3 and others.
I've overclocked it to 1.6 and it's stable (fast..) and hot. But I'll follow your advices. Thanks a lot!
dont overclock over 1.4Ghz if you have arc and you can always undervolt to save some battery juice

U need apps for undervolting such as setxperia, voltage control, etc.. Reduce the voltage and test it for few mins then again lower the value until ur phone auto restarts. Tats the threshold value

yea obv..undervolting means supplying less voltage to the cpu at specific frequency. it doesnt matter at wat frequency the phone is running
It might work fine well above 1.4 depending on the quality of the CPU you have in your device. I am fortunate enough to be able to overclock an xperia arc to 1.8 GHz and have been running at this clock for 6 months. Even gaming at lengthy time with charger plugged in works fine.
I do not game every day and just listening to music, talking on the phone, texting, reading a webpage or watching a video will not run the CPU at full speed all the time. Battery live if also fine for my usage 1-3 days. I prefer a snappy and responsive phone.
Running at very high clock speeds is at your own risc, the cpu chip design should be able to handle the high temperatures. I have allways overclocked my phones and have not yet been able to kill any of them, maybe I have just been lucky. There could be a poor soldering that breaks when it heats up, only push it to the limits if you can afford paying for a new phone
1,6 GHz on XArc by Sirkay = epic speed.
