HTC Desire overheating

My HTC Desire has a serious issue with battery life. Although I shut down most programs and connections, the battery lasts about 3 hours only. Also I have noticed that the phone gets quite hot on the back by the micro SD card. Do you think that my phone is faulty?
I posted the same question on,
http://www.htcdesireforum.com/htc-desire-troubleshooting/desire-overheating/
but not many inputs, does anyone else got the same issue?

mmmm 3 hours? i think its faultly.. my one last more or less a day with normal usage. gets warm when i use it a lot.

checkout the thread on excessive battery usage before you deem it as faulty.

There are many tips in this thread and how to identify which application is using the most battery, and which are causing the device not to sleep correctly. Its a long thread, but worth the read.

If it is only lasting three hours no matter what you do, and it's getting THAT hot, then yeah... I would say there is an issue. Maybe it is shorting out somewhere. I would take it back if I were you. It can have poor battery life under VERY heavy use, but that's still pretty extreme... and I have never seen my battery get above 39c.

I had this last night, but only while I was charging the phone. I pulled the battery & it was around the microSD that was hottest. Took it out & replaced n rebooted...haven't had any problems since.
Doub't the microSD caused the problem but might be worth a try. Either that or when I rebooted I didn't start the app that caused the overheating.
Does it overheat if you just do nothing with it when u reboot?

Hot Battery
I received my HTC on Tues night and within half an hour the palm of my hand was burning inside and yet still not healed (Thurs AM). P10 of the safety guide says this is nonionizng radiation (sounds unhealthy). I believe that the aerial is just beside the SIM and card slot and holding this next to your palm is warned against in the manual. Bit strange since that is how you would hold a PDA. However, I informed my service provider (Three) and they said it must be a fault so are replacing (with new apparently). Slighlty concerning however I will reserve the option to refund until I see the new handset. I might add that I have HTC's XDA Guide for bus. and that battery also gets very hot, but not as quick! Why put an aerial next to a battery, the combination of the two, I beleive is casuing heat issues.

my phone gets extremely hot ! sometimes up to 56 degree C !! and suddenly it reboots!

My phone was charging, WiFi was ON and I was browsering the internet, then i watched a movie. suddenly it started to smell like pommes frites. The phone was lying on a sleeping bag ( which is air tight and works like a heat shield ) and seriously it almost went flame on! lol

I would seriously reconsider your usage when charging. The highest mine has gotten was 40c. Just take into account that the bottom of your screen will also get near that temp, so be very careful

highest I've seen is 38°C, I believe above 45 is extremely hot

I've had to send mine back to HTC for "stress testing" as mine can't even get past 33°C without going into a reboot loop . It gets that hot just with some light use of GPS + Maps or Mobile Internet + Browsing.
Hopefully they at least replace the MoBo or possibly even the whole phone doubtful though...

hehe, my active holder in the car is in such a place I aim the vent/blower at the back of the Desire. No overheating while navigating with the airco on!
But I guess having something this fast (1ghz) in such a small package which uses quite some power as well means it's going to be hot real fast.
Although I don't find the Desire -that- much warmer/hotter than some of the other phones I've owned.
I guess when your Desire gets really hot (over 40C-45C or something) you can always give HTC or the warranty service a call. Perhaps when some parts don't sit properly on the cpu (something like a cooling frame or whatever), temperatures will rise a lot. And might even cause the phone to reboot.

Hi, I had similar problems that is very evident when i started playing games. I sent back to HTC 3 times before they finally replaced my mobo. I suggest you guys do the same

Temperature

Actually how hot can the phone sustain without damaging it? Cuz I plan to put my phone inside my car during my sch lesson ( where my sch inhibit students bringing phone during lesson or else will get confiscated ) , but the hot weather make me worry bout hw hot the phone will able to be sustained without creating any damages on it?

hello!
its a strange question because it hasn´t measure for it logically
i think that its better put it in the poket LOL

Hi Bert2662
I've been asking myself this question before. As the country I am living in, Malaysia, is hot and humid kinda whether. Constantly it will make my battery temperature on an average of 32'C.
I guess it should not exceed 35'C, as it is considered quite hot already. I am using a casing for my Desire HD, and even with that, I can feel that my hands became pretty hot.
Based on my own feeling(no empirical evidence. Lol.), that it should not exceed 35'C as it can damage your battery first, then hardware.

Hei, I'm also from I'm from Penang! I also have my phone with a cover. But I think the temperature in the car rili nt suits it.. Lol..

lol..i'm from selangor!! Anyway, i read some where saying that max battery temperature should not more than 40C, it will reduce battery life or damage it later. As for CPU, and electronic item, max temperature should not exceed 50C.
Edit: When I use my phone for browse especially, temprature getting increase very fast. Especially when you outside during hot wheater. Just in 1 to 2 minute, battery temperature already reach up to 40 ~ 42C!!

Hi Malaysians! Oh, i live in Selangor too.
Yea.. I reached once at approx 40'C and that time i do not feel secure anymore. (again, based on feelings. Lol.) From that day onwards whenever I have the chance to cooldown my phone i will just leave the phone on the table to have some air-con. Of course not for places like mamak, but places like in offices. Lol.

Lol!! The hot weather make me feel no longer think bout to put my phone inside d car. Unless I cn park inside d sch cuz currently I park my car outside d sch. By the way, it's good to separate the battery frm the phone if I rili need to put d phone inside d car

Remove the battery? Perhaps you bring along the battery with you wherever you go and leave the phone inside the car. Lol.
By the way, if you really want to do that, make sure you do take the battery with you. I notice many people has lost their valuables is because they left something in their cars. Well not much about the battery, but i heard that they have sensors to detect batteries or something metal for such as laptops and handphones. The Desire HD is also made up of aluminium. So.. Lol. You decide.
Again, this is what i heard only. How true is it will depends on how you look at it.

I'd just take it with me to class, turn it off and hide it (in a bag or something).
Problem solved
One a side note, I don't believe that schools have the legal right to confiscate your property, but it might get you into all kinds of other trouble.

Hi frosty_ice
Yea.. school do not have the legal right. But they will still confiscate your phone. I guess it applies to most schools around the globe. Probably private schools have more flexibility. Well you can bring your phone, but you have to give the teacher to hold them for you. Ish.

you dont have to lay your phone onto the table ^^

[Q] CPU overheat and crash, help?

My wife's Epic 4G was working fine yesterday but today it crashed and overheated pretty severely. When it was still plugged in and crashing it showed the battery charging and then it turned yellow and show a yellow warning triangle with a thermometer beside it, is the phone going to stop working on us?
I would appreciate a quick response so I can take it to Sprint and see what they can do about it.
I just factory reset it to insure that it wasn't a rogue application or what not and the phone is still running slow, not as bad as when it was crashing, but it still works so I don't know what's going on with it.
Also the phone is stock and has always been stock without root or any other type of hacking, etc.
It just stooped working perfectly one minute.
She showed me that the screen was blinking rapidly in an up and down bar fashion on the home screen and during applications.

First of all how old is the phone. My phone runs games hot all the time and never crashes (well sometimes, but usually when im not even doing anything with it).
I would think that the video is going out on it and it is rebooting. Depending on the age I think your phone is dead dude.
Cheers

Not a year yet, it'll be a year old in June or July. I'm hoping it was just a virus or something because its working now. Should I exchange it anyway?
Nabbu eats your face.

Try flashing it back to stock or wipe the data if it isn't already rooted. I've never heard of anything of this sort... need some screenshots or something.

I already factory reset it and it's running right now as if it were just fine but what I'm wondering is if it's going to happen again and not work afterwards.
I'm thinking about taking it in to Sprint and exchanging it but I'm afraid there might be fees for exchanging or what not. The phone has been dropped multiple times but it never had any issues before.
The drop distance has been less then 2 feet every time.
No water damage to the phone itself but the Sprint tech said the battery's "water damage" indicator was activated and showing water damage.
The phone HAS been in the bathroom during multiple showers which might be the cause for the battery's damage indicator to go off but the phone, like I said, has never had any issues.
She downloads pretty much everything from the Market so I was suspecting viruses or malware and now it's "clean" it's running fine.
Any suggestions for where I should go from here?

The phone should be fine. This has happened to me a few times.... if your phone gets extremely hot it will refuse to charge as a safety feature and show that yellow triangle thing... open the back of the phone take the battery out and let it cool down.

That's the best advice i've gotten on here! Thanks a ton! ^^b

Happened to me my battery got near 118*F so I took it out and let it cool on some aluminum and put it back in was fine
BTW you can't take a screenie because phone shuts it self off
Sent from my SPH-D700 using xda premium

I'm guessing that the overheating problem had to do with a buggy app that was running on the phone and took lots of data or cpu time. This has also been know to happen when running wifi hotspot apps.
Regardless, like everyone else said the phone went into thermal protection mode. The battery got hot and it wouldn't charge the battery until it cooled down.

Could be the screen being on and maybe running a governor such as "performance"? Also, I've left my phone under a pillow charging, woke up it was 110F and I haven't had this problem it mustve been really hot

THIS! ^^^ Without looking at your phone, I'm guessing this was the culprit. She had a buggy/defunct app that was probably frozen in the background while still sucking CPU/RAM. I've had a few of those instances and it DEFINITELY increases the temperature of the phone.
Only other thing I can think of is if she runs her phone at the brightest setting and has a long timeout on the screen timeout. Either way, I think it's nothing a little spring cleaning of the apps and tweaking couldn't take care of. Good luck buddy

Extremely high phone temp!

Does anyone have issues with your SGSII T989 phones having extremely high temps?
I get it when using the GPS, charging the phone while i'm talking on the phone, and doing a few other activities. It did not do this on my first purchase of the phone and i'm a bit weary of the temps as sometiems it gets quite warm!
Currently I'm on O.E. SGS II Rom w/ root, that's about it! No OC no mods or anything of that sort. (Just CWM and Root).
Any tips would be greatly appreciated, as this heat as caused me from using my phone each day more and more.
P.S. I WAS on Juggernaut Rom and then flashed back to Stock, and it was having this heating issue then, should i try to do a complete 100% wipe like on one of the development threads and start from scratch like I just got the phone from the factory again? I wiped my system using Odin and it seems to of kept my old programs, no information like games and etc. was kept however, does anyone think that might be the problem? Once again thanks!

If you are rooted you might want to try a different kernel and maybe SetCPU. I had some overheating/temp issues a while back and after I lowered my CPU a bit and set it to an Ondemand state with a profile for screen off running CPU very low when not actively in use it seemed to fix the problem.. Btw SetCPU is free for XDA users, there is a thread somewhere in the Android Hacking Apps forum..
GL
Edit: I thought it was free to xda users, I checked and cant find the thread, maybe I was wrong or they changed it..

I'm on the stock kernal, I was on the modified 1.7ghz kernal before i believe, as I could overclock over that, but i just recently stopped that and went back to stock. I was and still am expecting the phone to malfunction on me sometime soon lol. It's been a really reliable phone so far! My G1 and Mytouch 3G slide (gf's phone) took soo many dumps on me while I used it. Each of those phones were probably sent back 5-8 times and they were kept completely stock for a while!
Back on subject though. Any kernals that go well with the factory rom? I don't favor any aftermarket roms right now as they're not stable enough for my usage IMO.

I have heat problems but I've always had the stock kernel...

Undervolt at the stock clock if you want to lower temps. However, charging will always increase heat especially if you are using the phone at the same time, and depending on ambient temps.

Dude my moms sgsII literally got fried because it heated up once. She was using her phone normally and all of a sudden it started heating up. She kept using it and the next day the phone won't turn on, charge or get into download mode. It looked like what a hard brick would look like. So I just returned it for a HTC one S.
Btw she was on full stock.
My phone heats up a lot because I'm down south with 90-95 degree temps and I keep phone in the car dock by the windshield but it never failed on me.
Sent from my SGH-T989 using XDA

I thought it was a well fixable issue. Guess not? lol... Either way, everytime my batt temps rise, i notice i get 40-45C and i start to get worried. So if i'm in a car, i'd just put it next to the AC vent while the car's running and temps get down to about 25C and i'm good again. I just don't feel comfortable with the phone anymore like I use to. It never did this before, why now??

I have an app that warns when it goes over 40 and it happens daily. I was downloading torrents one time and it keeps the screen active while downloading and the thing got like 62 celsius before I realized what happened. It almost burnt my hand lol. if your ever in sunlight or palming the phone while using gps on 4g.
overheating is very common with this phone I wouldn't worrie about it to much it is uncomfortable though if in your pocket

Also remember, any app that uses hardware acceleration for graphics or video (games, browser, etc.) or gps will cause the phone to heat up if used for a prolonged period of time.
Playing Osmos was like setting my phone on fire.

Are you sure I shouldn't worry? I mean, I don't want solder points falling off due to too high of a temp. Then again these temps don't even reach 100C yet. I've got the same app too probably, it's a battery monitor that tells u when the phone gets too hot. mine's goes off everytime i'm around 40+

Yep, I use GPS and often. It's just so much easier than guessing your way off a piece of paper. But yeah, like you the phone gets soo hottttttt. I have to always put the phone to my AC vent.

It's normal to a point.
These are serious computers we have.
Think of the old P486's back in the day, those things needed huge heat sinks and some even had fans
our phones which is what, 4x the cpu power and not only no heat sink but everything is squished together inbetween a hot screen and a hot battery
That being said, I use a program called A-see, which is to watch my security cameras while out.
And if I forget to close it out (Actually exit the program) It will keep running and running and eventually probably fry my phone
lets put it this way, I will actually start to feel it in my jeans pocket, it gets that hot.
Also I have a program which will alert me if my phone gets to 130 degrees F
And will automatically shut the phone down if it gets to 140
overheat protection or something

I had this issue where whenever I try to charge my phone it would overheat to the point unbearable to touch I went back to stock flash different roms in the end i exchanged it it was still under warranty

Tmobile version overheating

I've been reading the other thread about overheating of the S4. Mine will get warm to hot just by downloading from the Play Store and playing withe the menu. I tried a factory reset, microsd reformat, etc.

Sure - any huge data usage, (especially with 3g/4g/lte) will cause the phone to heat up in the cpu area - this can be coupled with high graphics usage, and/or high ram usage -
electricity generates heat as a waste product - it wont get too hot, but it will heat up.
My gs2 would occasionally get so hot i didn't want to hold it or let it sit in my pocket
My new gs4 got plenty warm when redownloading my podcasts, and durring the first google device restore.

For me so far, the only time it is noticeably warm is when I use the camera for an extended period of time. Haven't played any intense games on there though like NFS.

I find that my microsd card get hot when accessed a lot, but that's not new, same as in my S3.

Mine is hot too. I haven't done anything though.

I believe there is firmware update that is compatible with the I9505 Tmo variant. You may want to do some searching and check it out.
The main S4 forum is a good place to start.

Heat is not the same thing as over-heating. These chips have a maximum operating temperature rating of upwards of 70c. There are a myriad of reasons why any two devices would operate at higher or lower temperatures including ambient temperature, radio actions (high-throughput or low signal recovery), and of course running processes. There will always be people who think their phone is "too hot" since it is a purely subjective claim.

yeah honestly is at 40c and thats beyond hot!!

Yep, mine heats up on the top back of the phone. But it doesn't overheat when I'm on the phone though. I talked for over two hours and the phone stayed cold. But if I play around with menu and installing apps, it gets noticeably warm. I used S2 for two years and didn't remember it getting this warm.

Like others mine heats up at the top back at times but never to a serious, uncomfortable degree. Pretty sure my Blaze would get hotter at times from less taxing usage.

So hopefully this is just software related issues and not hardware.....

I have to wait 20 days to exchange it. I could return it but my micro SIM card doesn't work on the S2.
Anyway, I just received an OTA update.....

I've used my micro sim in a GS2, a MyTouch slide and a G1. It will fit, just line up the 3 pins to the 3 plates on the sim and it will work
