Overheating, random reboots.. out of warrenty

Hi, I have a HTC desire, its nice but it gets hot latley when playing games like angry birds for a bit when the battery drops to 20% or so, and I plug in in.. it starts doing reboot cycle.. I think it only happens until the phone cools down.
I know the only real fix for this is a new mainboard, but I am not under warrenty..
any suggestions on how to live with it, or work with it.. someone told me a bad sim card or sd card might do this to the phone... I have already put 2.3 on it and factory reset and such...
thanks

How old is it? In the eu the warranty is 2 years.

Wow, good to see im not the only one. I have the same problems, and depending on the rom they get worse or better. im running CM7 now and i have little problems, but when i was running the ICS beta it happend a lot, both on and of the charger and in my pants pocket or out.
If its overheated and i take out the battery i can smell a sort of molten plastic / overheated electronics smell.

for me it was the same - main problem is motherboard.
in the end service center exchanged for me motherboard and now this problem is gone.
but before this exchange i did following:
* decreased max cpu speed to 576-768MHz (via SetCPU)
* in one of old kernels I was able to manipulate with CPU voltage level, so i was decreasing it for all freq. which was used by me.
* charging only via PC usb ports - when it was able to be fully charged and not overheat
but the proper way would be only to bring your device into service center...

I would also suggest decreasing the max speed

might be that sleep mode doesn't work entirely as it should in some roms, not making the CPU frequency drop enough when the screen is off.
And your device might be getting old and wear is starting to show.
If it's actually damaged, replacing parts may be the only solution

This is a known problem for the first devices. The solution is to change the motherboard, of course at the service center.

You need to pick a good firmware I worth Runnymede AIO V 5.0.1 Special Edition-> Base Runnymede 1.22.461.2 Official Sensation sense 3.5 Android 2.3.5 [CM7/r2] [STOCK] [AD2SDX] [A2SD] [BEATS] [RCTWEAKS] [Aroma Touch Installer]
no problems found! the same problems arise Earlier.

How did you void your warranty? Rooting or installing custom does not void hardware warranty. At least I got my pvt1 motherboard replaced even when I had rooted and used superglue to fix some broken plastic under back cover.

Ya, the phone is just out of warrenty, it really is only 1 year in Canada.. no ifs ands or butts...
But the phone only seems to do the reboot loop when I play angry birds when the battery is low and or when I play angry birds when the phone is charging ..
I think it happend once in google street view...
in other words intense apps... that make the phone warm up and then the sensor tells the phone to restart to protect the processor from overheating, but when the phone reboots the thing is still hot so it keeps rebooting.. only solution is to take the phone battery out and let it cool..
I guess this problem could get worse but it doesn't happen with normal web browsing at this point. I might have to live with it until I find someone to replace the mainboard cheaper than HTC wants.. otherwise not worth it.
I guess lowering the CPU max might be great so it doesn't overheat in the 1st place, I will try that.
I don't really understand rom, I have 2.3 gingerbread, is there something else I can change to perhaps get a better radio signal on this puppy ?

I have this problem, although until recently it only when trying to use it as satnav.
I'm glad to hear it's a known problem though.
I contacted my provider and they said perhaps the battery is getting tired and causing it to reboot due to lack of power. I pointed out that it was the other components near the sim & sd card slots that were getting hot, not the battery, so they sent me another one. I did buy another battery too and that has made no difference either. As soon as I rooted the replacement phone it started getting warm too. I'm also pretty sure that the "replacement" was a refurbed one, since the optical joystick doesn't always respond and when typing msgs sometimes the vibe feedback stops working mid-word.
It's very frustrating not being able to use it for navigation any more (although it works happily with My Tracks for recording routes).
However since I've rooted it, I don't think I'd get away with requesting another replacement phone. I've tried installing other rom's that might run cooler, but when I do they always lock at the HTC splashscreen and I have to restore nandroid backup.

Hello,
i'm new to XDA developers. Should i buy this phone? I'm thinking about it these days but i'm not sure if it is worth. Thanks for your answers.

The same Problem on my Phone! While charging i can not use my Phone.
My solution: Don't touch while charging. :-(

I think I have same problem...my Desire in regular use get worm at 35% and at 38% burns my hand...and what is wors,for 15/20 min. regular use(not havy or gaming) temp. rise from 28% to 37% but something confuse me...last night I play 3d games for an 1 hour and at 20 min. I put it on charger and continue to play games and 40 min. later temp. is 40% and stil no reboot but butom side of phone(not battery...front side (buttons and screen) and back side) is so hot that I can burn my hand on it. I put statistic that battery indicator show(time,%,temp.). So is it like that to you guys? Is your phone have that heat thing for 15 min. of regular use?
Its pic of last night 3D gaming and its all statistic of temp./ % / time...

Ok, sounds promising. Can you elaborate on that a little bit please? What settings did you use etc?

Ahhhhh.... My gf phone having this issue.. and i think the problem is the sdcard, class 2 and use it for a2sd..
But, i tried to unroot the problems still happen, even without sdcard, the best way for me is leave this phone.. :-(

simply installed it, and it had it run at lowest speed on idle so it could remain cooler
(you can check the settings on it to see what it runs on idle and modify to your needs anyway)

I have similar problem like yours. I suspect the problem is come from SIM because there is no this kind issue happened IF turn to flight mode or tool out the SIM.

Can dropping a phone make it slower?

Today...the unthinkable happened.
I dropped my phone from about 3 feet!
Luckily, I had a case on it, and there wasn't any damage to it...cosmetically. When I went to make sure there wasn't any internal damage, I tried a SetCPU stress test, a quadrant benchmark, an antutu benchmark, and a Linpack benchmark.
SetCPU was stable, quadrant was higher than before, and linpack was about the same. However, when I got to Antutu, my score was about 1000 less than before.
Before, I got RAM=~950, CPU Integer=~1825, and CPU Float=~1427. However, now I get RAM = ~700, CPU Integer = ~1350, and Cpu Float = ~1150. Everything else was about the same.
I should also note that at the time of testing, the phone was pretty hot (100 degrees Fahrenheit). The original scores were achieved on 80-90 degrees. Would you say this is a coincidence (and it was caused by heat), or hardware damage?

Coincidence.
Sent from my Galaxy Nexus using xda premium

I can run quadrant twice, doing nothing between tests but push the start test button, and get two completely different scores.

It was the heat after all. I let it cool down to 80 degrees fahrenheit, and it's back to the normal 6000+ scores. I feel so relieved now.

Did you pick up all the binary bits from the floor? Maybe some bits fell out so phone is still busy looking for the missing bits.

You're fine. Luckily the phone was ok. I think I would crap my pants. What case are you using?

My HTC One M8 fell by 2 feet. On the corner; has hard shell.
After this, the phone was very slow. The kind of slowliness I do not try to dig, and just reboot. Reboot took over 5mn. Then, phone kept screen off; I knew the phone was working: received a phone call; power button was working fine because long press on it could light the flash (Xposed customisation); volume buttons also work fine. After long press power+volume, I could reboot, and during reboot, the screen came one again. Screen could turn on each time I rebooted. After boot was completed, if I let screen timeout and go of, no way to turn it on again.
If I don't let screen go off, and keep it busy, and try to use my phone:
- background image animation lags a lot
- tactile screen works almost fine
- apps are responsive, but viewing on screen lags a lot.
- all system tools report a good iddle time, low load, and available CPU and RAM.
- the whole phone behaves like when it's over-heating, but temperature was low. The problem was perfectly reproductable during several hours.
- system behavior could also be compared toa computer working with full software rendering, without any hardware acceleration. CPU and RAM feel good, CPU reports iddle time, but graphics lag.
Power button was working fine on hardware side because i could use it to force reboot, and switch light on. But power button could not turn screen on. Hardware of screen was working fine, because after reboot, i could get a working screen. But, how could a simple fall produce a software issue ?
I had replaced my battery myself some time ago; so, I know that I have not glued it the way it's done at the manufactory; also I had to break tapes, and could not replace them. I have placed all screws correctly. My thoughts have been:
- CPU or GPU are not strictly overheating, but, maybe their physical connection to heat sink is bad
- maybe the battery moved a bit, and is pressing against something, deforming a heat connection, or pressing hard against a sensible component (and alter it's value)
- inertia could have pulled a cable out of it's plug; maybe there is a bad connection somewhere. Power lines had poor connexion providing too little current (or undervoltage); data line disconnected.
If the GPU is partly broken, system can fall back in software rendering, and a broken GPU may not imply a loss of screen; just switching to an other video mode.
After leaving the phone off for 1h, and rebooting 12 times, phone works perfectly fine again.
There is no way this could be a software issue.
It was a hardware issue, that had very little impact on something, and fixed itself after some hours.
May not be GPU itself, but really thinck it was "video related".

[Q] Sgs3 Display issue

Hi
I played Hungry Shark Evolution and my smartphone gets very hot, then suddenly it hangs and shut down.
Now i can start it normaly but i get this Lines movieng up and flickering, also when i switch off the display with poweer button it
dont come up again until i do an hardreset(remove akku or hold powerbutton).
Anyone an idea what is damaged? Display or GPU ?
I make a video and published it on youtube but i cant post links
Thx 4 Help

Have you tried a factory reset? The CPU may have gotten stuck at a high workload and hung/burned itself up a bit. If that's so I'm not sure which would be harmed. It might have been the screen because the high heat.

display or gpu,cpu

Yess i did a factory reset and add a omega Rom 60 on it. works flawless except the display lines and power off issue.
If the display is damaged i just can threw it away cause a new cost 100€ same as a used Device.
But if its an hardware issue i could buy a cheap one with broken display.
Big question what could be damaged..

[Q] problem with the shutting down sm 211

Guys, please help . SM211 became randomly shut down . During charging and standby time is working properly , and during the active battery life it off. CPU-Z shows CPU temperature is constantly 80 °, but the body is cold. Tried different kernel and firmware , the result is the same. What could be the problem ?

Greetings aosaid, It sounds like battery problem. Can you tell me which part of the device is heating up?

If you look at the screen , the left side a little heated when I play , it has always been . The battery temperature is normal. Now charging, temperature is 29°.
I did calibrate the battery . The charge keeps well .

If you are rooted, you can download cpu control app to decrease the cpu frequency. See if its working.

Yes, rooted. I limited the CPU frequency up to 1 GHz, it has not helped

Try the following link:

http://supportz.com/prevent-your-android-device-from-overheating/

Thanks for the info. But it does not help. The fact that any program displays temperature of processor 80°, always, it is not changed. No matter what I play or tablet is just lying on the table with a minimum of running applications. Even when during the game heats processor that is felt on the case, cpu temperature shows 80 °. It seems that the temperature sensor is not working properly. And the battery is always normal temperature, and shows adequate. I'm not sure that the temperature does matter at all. Yesterday the whole evening I run different applications, played a lot, the tablet never turned off. I want to check there is a dependence on the Connect to the network, wi-fi or 3G.

sounds right, sometime sensor might fail.

Forget about the temperature . I noticed exactly convinced that it is switched off only when I use the data transfer via 3G. When I connected to wi-fi, everything works fine and without chrarging.
sorry for my English, I'm ukrainian

Alright then,

So, nobody can't help?

I have a theory but idk if its proven. If the device got heat up and the sensor tell the system to force shutdown to prevent further damage. Thats what i have thought of. I think if you can get a new battery and see if it works.

still, I carried the phone for repair. the problem was in the connector on the battery. only. repair cost the $ 5. I thank you for your help

Question The camera does not work in the cold

Hello friends. I recently bought myself P6P (US Ver.) and I was very surprised when I noticed that at temperatures below 0°C (-1°C and below), my camera stops working. The phone simply freezes and when the camera starts, leaving for a reboot. After rebooting, the problem does not disappear until it cools down. At room temperature, or plus temperature at street (about 2-5°C and above) a problem, there is no. There is a cold winter in my country, I do not argue, but any phone, even my old one, broken s21u did not show such problems. I like to shoot stories on the street, take photos on the street, send video messages on the street. I cannot do this with a pixel. I have to wait for spring to use it comfortably. I saw a similar video of a Canadian blogger with this problem, but everyone else says that they have never encountered this problem. I am really offended that absolutely any phone can remove at this temperature, but there is no pixel. Maybe someone knows what the problem might be, I hope for your help. This is enormous suffering for me. I really love this phone, but his behavior with a camera on the street... This is not permissible for such a smartphone.

It was -4 to -6 where I am and I didn't have an issues when out and about

Sounds like a hardware defect, maybe bad battery not supplying adequate current at low temperatures? I've used my camera at 20 below without any issue.
I'd suggest trying it with an external power source (USB) to see if providing more current helps.

This is clearly not a battery. If the problem was in it, then it would simply reboot. But it just freezes tightly, then reboots. Sometimes when hanging, artifacts appear on the display.

Nothing "simply" reboots. Something has to happen to CAUSE it to reboot. If the voltage drops too low, the CPU will brown out and whatever is running will crash, then the watchdog timer will cause it to reboot. What you are experiencing sounds VERY battery. Try external power before dismissing a suggestion.

I put it in the freezer for 15 minutes (its temperature is about 10-15°). When I connected it to charging, when I started the camera, he immediately went into a reboot, and did not hang as usual. When I tried to open the camera without charging, it first hung, and then rebooted.

It is strange for my part to think about the battery, because my p6p was activated only 3 months ago. Its battery cannot be worn out, unless of course it was a factory defect.

Keep it connected to the charger the whole time. Plugging it in causes all kinds of systems to suddenly activate and breaks the test.
