[Q] CPU Overheating/Prevention - Desire Q&A, Help & Troubleshooting

Hi Guys,
I've recently got my desire back from a warranty service. The CPU was overheating causing the phone to reboot frequently, usually when browsing or playing games for a while. In the end they replaced the whole main board.
My question is has anyone had a similar experience?
I want to avoid the same thing happening again.
Are there any good widgets out there that tell the temperature of the phone?
If so what is a safe temperature?

I use system info widget, it also has some other nice features.
Actually idk what a safe temperature is for a device of this kind...i've never gone above 42° on normal use, and that was while playing asphalt oced @1384 mhz. Other than this i remember that i once forgot the phone on a radiator (lol) and it was 54° when i picked it up again, but still it didn't feel sluggish/unstable, so i must say i'm pretty impressed
Anyway people use to set the failsafe profile in setcpu @50°, so i guess anything above that can be harmful.

[Q] MikFroyo 4.6.1...runs hot?

Anyone else having MikFroyo 4.6.1 running REALLY hot when on a call? I have noticed this now on two calls over 5 minutes long. It is just the top of the phone, like nearer to the speaker than down by mic. This is hot like I have to move the phone away from my ear....not just warm.
This is very worrisome. I am running stock 4.6.1 with what ever was built in...no new kernels, no themes, no mods. I do have live wallpapers on as I want to see what they really do to battery.

No idea how I would check that...but like I said...hot enough to have to pull away from ear...not hot enough to melt...(at moment)
Way hotter than it has ever been on any other ROM since I have owned it for last 7-8 months.

The quickest/easiest way to check battery temp and battery stats is to download and use an app called Battery Monitor Widget. Also, any time I have ever had any overheating issues, it was usually due to one or two things. Either my phone hated the kernel that I was using, and changing to a different kernel (typically without havs) would solve it. Or I had a runaway app that was throttling the CPU at 100% for whatever reason. I would suspect one of those two things (or both) are the problem.

[Q] Desire overheating - Need to deroot?

Hey,
I have had an HTC Desire for about 18 months now and I rooted it about 6 months ago with a CyanogenMod ROM. It has developed major overheating issue and continuously shut downs when it gets too hot or run a processor-intensive application. I have heard that de-rooting the device could help solve these issues and am ignorant to the steps involved as I am unable to connect my phone via HTC sync to install a factory ROM on it.
I have read several topics and have come up blank. Maybe I haven't looked hard enough but any help and information anyone could provide me with would be much appreciated.
Thanks.
have you overclocked your phone ? (can you check your cpu settings )
maybe your cpu settings are to high , high cpu set may cause overheating and instability , have you tried other cm roms ? i find if i overclock my phone it warms up faster etc and becomes unstable
There are 2 things here.
Is it rebooting at intense activity and NOT overheating? If so, Overclocked at too high a frequency for your CPU to take -Take the overclocking down a Notch.
Is it rebooting at intense activity and IS overheating? If so, most likely hardware fault (PVT1 Faulty Motherboard most likely) - Return to stock and send to HTC for repair.
Overclocking itself should not cause overheating as most kernels are UNDERvolted, meaning even at overclocked frequencies, they are not using more power, meaning they are not generating more heat. An exception to this is ManU kernels, where it uses 1350mA at the high end, where stock kernels use 1300

Most likely a motherboard fault. I encountered the same thing.
seriously? ****... i've dropped mine once so they won't repair the damage probably... I'm having a similar problem.. though after i've flashed a recovery image, there's no problem!
I had mine repaired...3 times. Was constantly overheating and shutting down. Was a major let down when was using it as a car navigation. 10mins and it goes off just in front of a crossroad So after all it just turned off and..that's it. So my first repair was made in official Czech centre - got it back after a few weeks and it did work for a whole day..Then I plugged it into a wall charger, opened a game and just noticed the temp rising up to 43C..couldn't do anything, the next moment it was dead. Sent to repairs, got back after..a week. It didn't even turn on (sic!), so the guys at UK repair centre didn't even test it. But after another trial it's all good. I've rooted it, installed MIUI and just today S-OFF'ed it and flashed a custom HBOOT and now have a "BONUS" 130 megs. That's my story.
I've had similar problems and from what I read it is a hardware issue related to the motherboard that they will fix if your under warantee but programs like angry birds and navigation make it happen every time I use them with most roms. Some roms are heavier and more prone to reboots the roms I experience the least overheating reboots with are miui and oxygen but I love sense so just use a sense Rom and don't use games and navigation. A bit cr*?$%p I know.

Ok wel I'm on MIUI now, let's see what happens. Use it now for a day and have been safe still
Edit: aaaaaannnnnnnndddd it's gone....
This is going to be fun now that outside temperatures are rising...
What were you doing when it overheated, playing games or just watching it?

you are soo right lol ) if i use the phone outside where are @ +2°C the damn phone works like new... well, when i go inside, the whole story changes... the phone start rebooting and soo on... soo yeah.. it will be interesting to use this phone in the spring
It eventually crashed and never came back! Tears were cried, but I'm still happy with the nexus 4 followup.

[Q] Galaxy Nexus CPU temp

Hello all
This is my first post and Galaxy Nexus is my first Android phone.
So, when i bought my GNex it was on stock and I use Stock ROM about 3 days. In that period he never get any warm - not even whet I play Angry Birds RIO for about 30min.
Then my brother install me latest AOKP ROM and Franco kernel - great stuff, but now I feel heat around camera
I use TempMonitor PRO app and this is my results :
all apps close, not starting anything - around 32C
Gallery, cam, some apps started and closed - from 38 to 42C
Playing games (Angry birds RIO, Space, Sentinel HD) - 48 to 52C
My question is this :
Is that normal temp? How does Stock didn't heat that much
Tnx and i hope this will help if someone have the same question
Hi,
Your CPU temp is absolutely normal,no worries.And while playing games it's even perfect.
How does Stock didn't heat that much
Click to expand...
Click to collapse
You're not stock now...
After it depends at what CPU freq you're running,voltage,ambient temperature,etc...but here it's perfect.
I just posted in another users similar thread about their phone getting hot (he said "extremely" hot so hes likely going way past your temps). I too have found my phone to be warmer when running AOKP Build 38. I've run the Stock ROM and LiquidSmooth with Francos Kernel (also tried Provision briefly but it had some issues I couldnt overlook). AOKP gets the hottest by far for me (both at stock CPU and OC to 1420).
I plan on switching ROMs again soon and will take note of temp then
If you use a less feature rich rom you might have less heat issues.
I suggest using the trinity kernel together with a cm9 rom.

Your temps are fine but if you want to find something a little "cooler" try out different combinations. For me, CM9 and Trinity Stable 65 at 1344/384 stays pretty cool while gaming. Ultimately it is going to be a factor of your clock speed. You can adjust the frequency of your CPU back down to 1200 (1190?) and you'll see the temp difference. You might also see it slow down during certain UI interactions. Just play around with it, but your phone is still considered in the safe zone at those temps. They have thermal protection built into the kernels as well so even if something crazy happened your CPU would back off until cooldown and if it can't cooldown, it'll shut off for you but that would be a very rare condition. I've never had it happen and I've ran at 1650Mhz for a long time.
Tnx all for info. Great help!
Hmm it would be nice to get back to Stock but to keep root and maybe to install franco kernel... What you say about that?
It's iritating to play game 5 min or look pic in gallery and to feel heat in phone!
One more thing because I'm new in this stuff :
How to get back to Stock? Is it hard?
Your CPU is probably overclocked, don't worry, as long as it stays UNDER 55 degrees C, nothing will happen, if however, it goes over, it will burn your hand, if you're unlucky, it happened to me, with my GS II...

Hi,
Why under 55°C???
The stock temp limit before thermal throttling is 64°C and in Francisco's kernel it's at 75°C.
And the max before the CPU shutdown is 110°C...The extreme protection and the extreme overheating
So above 55°C no worries...In any case if you don't disable the CPU temp limit (like in some kernels->Morfic,Glados and eventually Francisco but not (yet) in his app) you're good and before 110°C->thermal throttling->lower CPU freq according to the CPU Temp limit.
His CPU temp is actually normal,don't say stays under 55°C....56/57/58/59°C,etc...to 64°C or 75°C,no problem unless you stay at 75°C during 1 hour...
With that you said the guy no longer used his phone for browsing 5 mins in the sun...

55 is a very low number and i would suspect most stock GNexs would go above that routinely under heavy load.
I've had my phone up to 66 and its nowhere near burning. Its warm to the touch and thats about it. Now if you are somehow putting your hand directly on the CPU (i.e. not possible) then yes that might feel much warmer.
Basically if you manage to burn yourself on your phone either its already fried or someone lit it on fire
After playing ShadowGun around 15min I get temp. around 65C?! That is really hot - for me!
I think to get back to Stock... This is way hot for me. What you say about that?
Can anyone post link how to get back to Stock? Guys this is my first android phone and if I get bootloop I will get a heart attack, really I will get one

Honestly don't be afraid of boot loops as you can most likely still get into recovery if that happens and all it takes it's a bad download of a ROM or forgetting that such and such kernel is incompatible. Be afraid of bricks and soft bricks lol. Although if you take the time to read before doing anything you'll be fine. Also just download a sick image for your phone from the tool kit to go back to stock. That's the easiest way.

Hi,
65°C after playing 15 mins of an "intensive" 3D game...I don't see where is the problem...It's absolutely normal...
How can your CPU temp will be at 50/55°C (about,for example) after playing 15 mins of game???
You hope what temperature?
Which cpu frequency?GPU?Undervolt?
Don't focus much on your CPU temp,if it's overheated->thermal throttling...And in extreme situation...just a reboot...
It will be the same thing with the stock kernel,you will get the same temperature under the same conditions (playing)...
Unfortunately that's the way it is right now with dual core phones. My phone regularly gets too hot to even touch when playing games for over 30 minutes. I called to speak with samsung about it and they pretty much brushed it off as normal. I'm running on cm 9 with a franco kernel

[Q] Overheating 🔥?

I just got my Samsung Galaxy s6 edge white 32gb last night and I noticed that is over heating than it should be. I'm using it for Web browser and texting nothing that should cause to heat up. I also updated to the latest version.

Actually if it was overheating then the phone would automatically shut down to prevent damage, but yes the phone does get hot rather quickly. But I've had glass and aluminum phones before and they always get hot fast since metal retains heat.
Mine ran a lot hotter than a normal glass and metal phone, and it was laggy/jerky. I flashed the stock firmware to it, and now it's smooth and cool.
Here's How:

yes it does get hot once in every 3-4 days & when I say it means really hot..

Smart switch is not working for everyone. Hit or a miss thing.
My phone heats up to 44 C
What is the Warning Level is it safe till 45 or 50 Celsius ?
It happens when
1) On use of Google Maps while driving
2) Charging
3) When i use Sandisk OTG, to the extent that it stop the Transfer & freezes
4) Even if i Record Videos sometimes
5) While wireless charging
This is really bad Never had such a Issue
I agree with some of the sentiments here that the device can seemingly get pretty warm - especially when I tweaking things or using apps that use a lot of CPU or using the camera for too long. But I do believe a lot of it is related to the aluminum/glass case - I believe Samsung is basically taking advantage of the case as a though it were a heatsink - releasing all the heat into your hand/pocket/air.
This is truly the first phone i've had that manages to stay under 100° F even when cpu frequency is locked to the maximum and I'm playing very gpu-intensive games, provided that i'm not charging the battery and the phone is not in an unusually warm environmnt like a hot car. I should mention that i'm rooted and lots of preloaded software has been removed. I would download some sort of process monitor and check it to see if there's a misbehaving app to blame if this is happening regularly.

Hey,
I saw that you posted a solution when someone had problems with his S6 edge overheating. I've an S6 and I think I might have the same problem.
I was wondering if you could spare some time to help me. I posted my problem here. http://forum.xda-developers.com/galaxy-s6/help/help-s6-cpu-getting-hot-t3180011
I used Antatu benchmark and CPU temperature to test my phone and it got to 84.0 C twice, once when it was testing my CPU to it's fullest and once when it was testing game performance.
So I was wondering if you could run the test as well and tell me what temperature you got so I can compare. Thanks
I haven't tried your method yet but I will tomorrow.

For the record, mine just hit 85C while running AnTuTu. As far as daily use, it made a world of difference on my phone when I flashed the stock firmware the first time. The phone was terribly hot in my pocket when I was not doing anything, and it was SUPER laggy when I was. Not something I expected from this phone. After the flash, it was a Beast and ran MUCH cooler. It would get warm still when doing intensive tasks, but that would be expected from an Octa-core phone in my opinion. It does not get uncomfortably hot anymore, like it used to though. I would imagine it went WAY above 85C when it got hot before, because it was actually hard to hold at times.
If you have not flashed it since new, I would highly recommend it. I know it's a pain, but it's a one time thing that you never have to do again, and the benefit MIGHT be large. No guarantees, as you may not have the same issue, but I've received a lot of reports from people who have done it and they say it breathed new life into their phones. For me personally, it was DEFINITELY not a placebo affect. It was night and day.
With all that said, I've got my S6 Edge up for sale right now as I've moved to Apple for a little while. I continually jump around, and T-Mobile offered the iPhone 6 for $15/mo and I can trade it in 3 times in the next 18 months for free and keep paying $15/mo for the newest phone. I'm looking forward to seeing the difference in the iPhone 6s. If it sucks, I'll be trading it in shortly for another Android phone.
PS: AnTuTu final score: 69314!!!! Wow!!!
One more thing. To eliminate ALL lag and slowdown, I replaced the Samsung Launcher with the Google Launcher. What a difference that alone makes! Seriously, try that one thing. It's huge. The Samsung Launcher has some issue somewhere that they still need to address.

It should. As long as Smart Switch can recognize your phone model and download the Correct Firmware, the Flash WILL help the Heating and Lagging problem. If your phone is not recognized, then Smart Switch will not do anything. It's worth a try.
For me it happens especially when im playing arround with that samsung theme store build in app. I don't know why that app needs so much power to have that effect on the phone but for sure its something samsung needs to look at.
For sure they need to re-design that app from the scratch. Its like the "my first homepage" of theme apps.

Overheating

Hey,
I still own and use an LG G4 as my second device, but the overheating is becoming a problem since it throttles like hell when the device overheats. Any advice / possible fix?
Thanks
What temperature is the phone getting to? you can install a cpu temperature app to check.
