HTC Desire Overheat Issue

For some reason my HTC at the bottom is getting very hot and rebooting because of it. I pulled the battery and with the charger in and battery out its still overheating. With just the battery it is also overheating and now it's not charging.
No software changed so it has to be hardware, can anyone tell me if their Desire gets hot at the bottom with charger in and battery out? If so I might be able to try a new battery (the current one isn't getting hot at all). Phone was bought second hand so I could be stuffed!
Cheers, Andrew

Sometimes with hard use (many downloads at the same + 720p streaming and charging) the battery take over 45C. But never reeboot. So i think you have a battery failure, or even worth, a motherboard failure.

I'm gonna go with what you said.
Doubt its the battery (not ruling it out though).
My desire kept rebooting when I used GPS / Wifi or mobile data. I just took it back.
Hope you're still under warrantee.

Nope, last phone I buy without one.
It's basically dumping all power including that in the battery into heat, I presume the GPRS chipset has failed as I lost signal. Battery drained extremely fast and now wont charge as the full 500mA from the USB is going into heat.
New mainboard time. Finding one though...

i doubt its a motherboard problem.
more just a problem with heavy use. maybe try not to do 10 things at the same time.
it is still a mobile phone afterall.

Err no, liquidmonkey it doesnt work like that.
IF its overheating to the point where its constantly rebooting, then its a hardware failure. All this stuff about putting phones in the freezer is a load of rubbish, just like the old Xbox 360 towel trick. If its overheating - its faulty.

just got my Desire back from vodafone, new mainboard, i already tested in sunny Lisbon (27c) working in the sun, for navigation in the car with google maps navigation, *
the old one, in direct sun lite it would not stay on for 5m.
Now it is ok!
and since it is a new mainboard and IMEI, i have a renew 2 YEAR WARRANTY . thx voda... lol
but that's not all, they also changed my screen from a SLCD to a OMOLED ???
and i don't think that's ok!
when i delivered my desire to vodafone, they lent one other htc desire to me, it also was amoled, but it add much better viewing angle, and less tending to blue.
my new screen was a very poor viewing angle because the colors tend to much to the blue when i tilt the phone, it also is very bright, does not have as much definition as the SLCD, and i think the one voda lent to me ad also better definition, but at least the black is really black and color very vivid!
do you think that what i have *seen, 3 different screen's in 1 week, and considering the characteristics of my new screen, are normal for amoled screen? ?
thx in advance (sorry for the inglish)

Mine will get very hot if charging whilst playing video or using GPS but I think its only rebooted once.
I have bigger problems with my other phone, in comparison the desire really is a cool phone.
I guess you could try under clocking it if you have problems?

Overheating - good news

Just to encourage anyone suffering from the overheating - get HTC to change the main board - it's like a new phone ...

I did the same... got the board replaced... they recognise it as a hardware fault over the phone and will replace the main board.... I've got a PVT3 now, I used have a PVT1

There is another very, very long post on this issue, and have been meaning to ask for some advice - this much shorter post has reminded me!
I also have the overheating/rebooting issue, have called HTC and reported the problem. Just waiting to sort myself out with a replacement handset before I call up and ask them to send the courier round... What I would like to know is, what is the best way to ensure that the main board is replaced first time around without any to'ing and fro'ing between me and HTC? How do you get them to recognise it's a hardware fault over the phone (I'm in the UK)? I basically just want to get my phone repaired ASAP and back to me ASAP without any hassle!! (and it's very ovious what the problem is!)

I also suffer from this problem occasionally.
I don't think I will bother sending it back to HTC as it will mean unrooting and flashing the stock ROM. I'm also due an upgrade soon so it will probably be more hassle than it is worth.
I may unroot it and flash the stock ROM and send it off to HTC after I have upgraded. I will then have a spare Desire or can give it to a good home.

Possible Fix for Overheating
Hi!
I have a HTC Desire with the AMOLED-Screen, which is said to be way better than the SLCD. I did a lot of research using Google and various forums, but did not find a real fix for my overheating phone: everytime i did more than just listen to music, my phone rebooted over and over again. It did get hot in the commonly described areas (around the microSDHC and SIM-Card and the little black square), and i had to rip off the battery to make it stop. I was really annoyed since i read that i would get a replacement without the AMOLED-Screen, that is why i decided to do some testing on my own. I found out, that i had less trouble with higher workload when i enhanced cooling by putting it in the fridge for example. (Other things like changing the microSDHC did not solve the problem for me.) When it comes to computers overheating, you clean them and have a look at the thermal grease between the chips and the coolers - and that is what i decided to do to my phone. On the inside of the battery cover, there is some metal-like shield in the lower area. I guess it is there for heat dissipation - but maybe it did not have proper contact. As i did not want to clutter the phone with thermal paste, i ordered a pad on ebay (for about 2€), cut it into smaller pieces and attached it to the parts that are known to become hot (see above). Then i attached my phone to the charger and ran a lot of apps, that would usually make my phone crash (Music Player, Skype, Internet Browsing at the same time). The back of the phone grew hotter and hotter (and was, in the end, a lot hotter than anything i have encountered over the last few month with my crashing phone), but it was stable!
So, if you are annoyed with your overheating HTC Desire: This might be a fix for you:
Buy a thermal pad (as it is used for CPUs, GPUs or Chipsets, mine was about 0,5mm thick) and attach it to the metal parts over SIM and microSDHC as well as the tiny black square and the area to the left of it. Mount the battery cover and enjoy!
Hope i could help
Terminator
EDIT: Turns out, the "fix" only delays the reboot-loop. It appears a lot more stable, yet it did still annoy me. Yesterday i handed it in for a replacement.

[with adb-log]Desire reboots on its own!!! (high temperature)

im sad and afraid because from the last week my phone is still rebooting after 10-20 minutes of 3g connection.
It's enought to surf with browser to see it reboots on it own.
It happend with ALL RADIOS from 32.44.00.32U_5.09.05.30_2 up to the latest radio!!
I tested also different roms: Insert coin, RCMixHD 2.0, ReflexS, Leedroid GB 3.0.0.7, Oxygen 2.1.3.
this is output of "adb logcat > test.txt" from powering on phone up to his reboot.
ROM: InsertCoin stable v1.0.8 and radio 5.11.05.27.
Bravo PVT1 Amoled S-off.

My telephone is broken?
Why heats up then reboot?

mine is with tmobile just now for repair for the very same reason.
from your log there doesn't seem to be anything apparent near the end of the log so it looks like its not software related error - I suspect CPU overheating and just bombing out before software realizes whats going on.

so...i have to send it for repair?
HTC service in italy is a pure shi.....-diplomatic mode on:- is poor service
Very slow and without service center in our country.

Solved:
It was an hw truble, htc service has changed motherboard and apparently seems to work good now.

PVT1??
I wonder... I had a PVT1 also and the same thing happened, got warranty repaired, I'm now PVT4.
Does anybody else know if it's just PVT1 Desire's that suffer this problem?

yes last series of many desire and hd2 also got same problem.. only board swap is the solution

Where did you find that the device heated up most because mine gets really hot but not experienced reboots.

Pretty much the area above where the charger/usb cable goes in. You can feel it on the back cover where the SIM and SD card are positioned underneath. Since I've had mine replace I've noticed the heat alright but no corresponding reboots as I got before the repair.

Me too; still gets warm in the same place (although nowhere near as hot as it did) but post-repair it was fine.
Until it wiped itself (literally - everything bar the bootloader, just gone) and had to go back again a few weeks later.
Have decided if it breaks in some manner again I'm going to drive over it in despair.

HI, I have the same issue ,but what really bothers me is if i need to flash the RUU rom before sending back to htc. I tested it with previous version (froyo) rom , and the problem just disappeared. So I wonder htc service will accept my request if the problem won't happen with an offical rom?

i have the same problem and it's already in repair since 3 weeks. Hope i get it back some time soon...
I flashed the original RUU before sending it in. Just in case..

After repair my desire is back pvt1 again and heat however in 3g connection but stressing phone or not is stable with no reboots.
Edit: i noted during charge my phone heat but again, no more rebbots
Only pvt4 devices have not temperature problems?

Hi,
when weather is pretty hot, when use GPS or high 3g drain app like watching tv my phone reboot on it's own.
it seems to happen when battery temp reaches 35°c as well
when weather is very hot sometime it enter into bootloops and need a battery pull to let it cool down.
i know how to see battery temperature :
adb shell
cat /sys/class/power_supply/battery/batt_temp
but how can i log it please ?
just to see if it's really a faulty battery protection or another problem.
Best regards

You can easily use 'Battery Monitor Widget' from market, by having it you can log temperature, current, voltages and battery percentage at preset time interval.

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.
Sent from my Motorola Startac running Atari 2600 software!

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.

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 ?
THanks GUys

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...

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.

I HAVE FOUND A SOLUTION FOR THE LG G4 BOOTLOOP ISSUE *Story & Tutorial*

Basically what happened, was on Friday, my phone got stuck in a boot loop. It would get to the "Optimizing Apps" screen and shut off again. Other people may just get to the Verizon screen, or even just the LG screen. I looked it up and found that it was a major issue affecting many people, so I just filed for a warranty and received my new phone today. Well, on Saturday night LinusTechTips, a popular tech YouTube channel(You should really check them out, they are great), released a video on how they fixed a dead Graphics Card and PCI-E SSD by heating them up past the melting point of solder and then testing them. For them, it only worked on the GPU. As I was packing up my seemingly dead phone to ship back to LG TODAY, i decided to give it one more shot. I disassembled the device to the point where I could take out the logic board. I took the logic board and wrapped it in one layer of parchment paper and two layers of tinfoil, shiny side facing in(FYI tinfoil has two sides, shiny and matte). I then placed this package into a barbecue. I turned on the left and middle burners and left the package with my logic board inside on the right side to the grill so it wasn't receiving direct heat. After 10 minutes, I took it out, re-assembled my phone and it booted. I was able to get all of my pictures off of it. This has only been confirmed to work on my phone, but seeing as this SAME issue is affecting thousands of people, It's definitely worth a shot. If you are going to use an oven, PLEASE, make sure it's above 385 degrees Fahrenheit and that you don't plan on using that oven for food ever again, this may release some toxic chemicals etc. I plan on using my grill again, so I just made sure to leave the grill open for 24 hours and I'm going to clean it before I use it next. If you have any questions let me know!
P.S. My LG G4 was the Verizon model.

I highly recommend doing this ONLY if you have no other option. Remember that heating a logic board to high temperatures can release toxic fumes. Don't use an oven you use for food preparation! Toxic fumes can leave residue in the oven and will be re-released upon reheating over many cycles!
Assuming LG's press release regarding the issue is correct and it is really a loose contact, this "fix" could actually work. Of course, only if the loose connection is a soldered connection. Though, it's controversial. You have to remember that the melting point for SMD solder is around ~350°C, or 662°F. So 358°F, or 181°C, is not nearly enough to actually re-solder a loose connection. My guess is that the loose solder point is only expanding due to the heat. There is no real reconnect. It might only be a matter of time until it also breaks. If you could locate the actual loose connection you could really re-solder it and have it fixed permanently.
I've done this on many many devices, including graphics cards, smartphone logic boards, PC mainboards etc. It only works if a soldered connection has a crack small enough that heat expansion is enough to gain reconnection. If there is a loose contact on the PCB or the "crack" in the solder is too big, it does not work. Also, if you really have a dead chip, this trick also won't (always) work.

I read a similar story on reddit. The guy put his main board in the oven, reassembled it, and the phone started working. The last update I read was 3 days later, still working.

I fixed mine temporarily by heating up the emmc chip using solder hot air gun. It seems to be just the emmc chips connection.
Failed again after a fortnight when the phone got too hot. The connection seems to break when the g4 gets hot.
One option to try is to boot the phone inside a freezer. I found that worked too.
Pretty poor quality control on lg's part.
I'm going to try again and see if I can fix permanently.

Worked for me too
I have a LG G4 H815 with serial number starting with 507. It died yesterday night. The bootloop escalated quickly to full death. Even the freezer trick did not work.
I followed the OP instructions. I heated up the grill to ~250 degrees Celsius and cooked the motherboard for 10 minutes.
Magically the phone has been working for a couple of hours since and I have been able to backup files to the external SC card.
I wonder how much more will it work.
Thank you for help OP!!!
Word of advice to other LG G4 users. Backup your phone regularly. Use an external SD card. Set the camera to save images and videos to the SD card. At least at doom day you will have them saved.
Cheers

What is the beginning of your phone's serial number?

Hi bro kindly tell is it worth to install custom rom kernal with root to prevent the cpu to clock high speed so it will not go into bootloop? My is also 2 years old thanks

250 degrees F for 6 minutes and brought the phone back to life. We'll see how long it lasts.
Actually it worked on BOTH G4s I have. I first just went dead and I bought a used one for $100 on eBay and it worked fine until the bootloop showed up.
