Heat - G2 and Desire Z Q&A, Help & Troubleshooting

So there is this story... One day I woke up (the phone was connected to charger) and my Vision was on my roms bootscreen (it was a htc sense rom I think)... Took it in my hands and it was super hot. Extreme overheat. Even more than SGS2 when playing hardcore games I immediatly pulled the battery and waited some 30mins... In the next evening I was afraid to connect it to charger and sleep, but I made the risk. And nothing happened.
So at the night when it almost burned it was on 1ghz, what in my opinion is not a big overclock and couldn't cause such an overheat... No other things were done.
At the next day, switched to CM7...
So can this happen again? And why it happened?

Battery malfunction ? i.e. the battery itself is dying ?

Was your phone turned off/just turning on when you went to sleep or did it reboot over night?
Anyways I think, since it obviously isn't a reoccurring problem, it was probably just an app or some system service which was caught in some kind of loop or other error which leads to a very high usage of cpu cycles and therefore your phone heats up a lot. Finally Android reboots either due to a hardware trigger caused by the rising temperature or because the OS crashed.
Once the phone rebooted, android probably tried to finish whatever it was up to and got caught in a loop once again which stalled the boot up process.
I guess that this can happen again, though I don't think that this is anything you need to be concerned about, unless it becomes a frequently reoccurring problem.

Overclock should have nothing to do with it. I don't think OC to 1 GHz involves any overvolt. Plus, unless you have the minimum clock freq set to 1 GHz, it was likely clocked itself down much lower than 1 GHz while screen off and idle.
Battery may be faulty, or some runaway process, as previously suggested.

i've heard that when the phone gets hot it stops charging... i may be wrong though...
try putting it back to 800 on CM ROMS... they're lite weight... and u have heat issues... so this could be good for you

I have had this happen a few times all due to OCing. Something in the system gets stuck in a loop and it will heat up FAST. I too have pulled the bat and cooled it down then put it back with no problems. I was always OCing in the range of 1.8 or 1.9 when this happened though. I would check your radio version too. The .19 radio gave me a lot of problems. I currently run the .30 radio on my G2.
P.s. the phone has a hardware temp shut off. So if it gets too hot it will shut off. Not something you want to have happen a lot though.

[Q] Battery Overheating Causing Shutdown- Battery life Uneffected

Hi guys
By current battery temp is at 33.3 degrees.
Battery life is uneffected. I get more than a days life out off it.
I never did any caliberation stuff etc
current rom MIUI
I just started monitoring the temp becuase 30 min ago my phone shut down hwne it was sitting right next to table lamb and the heat of the light from the lamp caused the phone to shut down and boot loop at htc logo.
I dont think this is a one off problem as i am getting boot loops on htc logo when playing games since last 3 weeks.
I even had to change my rom because once its got stuck in boot loop forever.
so i had to unroot etc
currently i am using MIUI
I didnt realise the boot loops were because of overheating.
What is the temp your battery is on?
Is there any way of checking temp on other parts like processor etc.
Does replacing battery help?
At this moment playing games for more than 10 causes phone to shut down. and sometimes to bootloop
What shall i do?
Probably another case of this.
Try a differrnt modified kernel other than your stock one, like VorkKernel or DeFrost.

Strange really fast battery drain Oxygen v2.0-RC7

I tried the Oxygen v2.0-RC7 rom a few days ago. Has been working relatively well with some minor bugs (like not being able to move icons without them dissapoearing). But yesterday something really odd happened and got me kinda worried.
I turned the sound off on the phone via the lockscreen, then locked the phone in my locker when i worked out. The battery was at about 80% at the time. When i came back about two hours later my phone was _REALLY_ hot and the battery was totally drained and the phone dead (ofc).
Anyone else experienced this? New user here so can't post in the official thread for the rom. What got me worried was that the phone was getting extremely hot.
There is nothing wrong with the ROM as far as battery drain is concerned. I have been running RC7 since release and with my current configuration get almost 3 days of battery usage before I need to re-charge.
I would suggest that it is more likely to be a rogue application that is constantly running in the background eating the battery.
If the phone was getting hot, I would suggest that an application is hammering the CPU (such as navigation) which would drain the battery pretty fast.
Odd thing is, I had the phone in my pocket for maybe 3 hours prior to this incident. Then it was at about 80% (remember because I checked when i turned off the sound). Then only thing I did was turn off the sound via the lockscreen. Didn't even unlock the phone at all. Then this happened.
Seems really strange. But it has only happened this once, and it is a homebuilt rom so I don't really expect everything to be perfect. Just that I've had the phone run hot before, just not this hot.
Was actually worried it had broke before i got home and put the charger in It was completely dead. Couldn't even start to boot up that you sometimes can do when the phone has died and then rested for a few mins.
could be a faulty handset, i had issues with my phone running out of battery pretty fast and after a warrenty replacement seems to have sorted it.
phone shouldnt be over heating...

Wasn't a metal locker, by any chance ? A metal locker would function as a faraday cage, meaning your phone would get at best a very weak signal, and would be using maximum power to try and communicate with the base station. Would explain why the phone was hot, too.

Phone on fire???

Is anyone else experiencing this?
While my phone is charging, if I use it, it gets wicked hot and I get an error that it has throttled certain hardware functions in order to avoid overheating...
Interesting, are you overclocked? Running stock firmware or a custom rom/kernel? But to answer your question, I haven't seen this happening on my phone. I'm running Viper rom, with the cpu governor set to conservative.
Stock rom with lostkernel here. It happens every time the phone is plugged in and I'm using it.
How is viper rom? Maybe I'll try that.
Also, not overclocked at all. I don't even have setcpu installed..
Mine gets really hot too. Its gotten up to 125F before. It lowers the brightness to "prevent" overheating. Others have said they have gotten messages saying that charging has been paused due to overheating. I haven't gotten that but when its really hot and I turn it off to charge I even get a temperature warning on the charging animation. I brought mine into sprint and they are going to replace it. I just have to wait until it comes in.

[Q] GS2 Constantly Hot?

The phone is on idle and not charging with nothing running on the background and it gets really hot for some reason. I exchanged my battery thinking it was the batter overheating but it still gives me the same problem. Any thoughts on what might be causing the issue? The phone is not rooted btw.
Exchange the phone. I had 7 of these and none got hot. The one I use now is stock but rooted and stays cool as the the fonz.

I don't think its an hardware issue that's causing your phone to overheat since this phone isn't known for having overheating issues. You either downloaded an app that is causing this issue or you need to either reboot your phone or do a full wipe.

i run my at 1.8 Ghz and it's not hot, it might get warm after constant use like 30 min, but it's no where near hot
i consider hot when the temp reads 50c +

[Q] Major problem with my One X

Got my One X on Friday (no sim card as the company I got it from had forgotten to send them out with the phone)
Have been playing around with it most of day yesterday, putting few apps on etc, haven' used it for games.
Last night when coming out of apps and going back to home screen was taking a while to display (kept saying "loading"), eventually home screen appeared. this happened a few times, I then tried to put a widget on screen and it just froze on loading and gave me a message to sat "Sense had stopped working" and then restarted. Thought I had best restart the phone so tried using the restart option and nothing, so went for switch off, which it did and now will not reboot.
Phone did feel a little hot on the back by the camera but did not think too much of it, when I try to turn on the phone I get the HTC screens then as soon as the homescreen comes up before you can unlock it the phone vibrates and shuts down.
Left the phone over night without charging it and is still the same this morning.
Have tried Factory reset, still no joy.
Led notification is flashing red/green constantly if you plug into charger.
Having read some about this on other HTC phones it seems my phone has overheated, but surely should have cooled down now after being off all night and not on charge (am in the UK so excessive hot weather is not the cause )
Finally received the sim card in post this morning so tried putting that in, still no joy, think I am going to put in in the garage as its really cold in there.
Any ideas before I send it back. I think its knackered.

The blinking leds means your phone is overheating, you better not use the phone while charing (until the problem is fixed).
The reason why sense 4.0 might be crashing all the time is because of the widget, if you use a Calender Widget it keeps crashing until you remove it! Try to remove all your widgets and see if that solves the problem.

Thanks for you ideas but.........
Cannot use the phone on charge or otherwise, will not boot up past the HTC screen, widget will already be gone as have factory reset the phone, not sure how long it takes the Phone to cool down but has been off and in a cold room for over 12 hours now, so don't it will resolve itself. An option for other HTC phones is to take the battery out to reset the problem, but this is not an option on the One X, just wondered if anyone had any ideas.

You didn't do any rooting I assume ?
The device is probably damaged in some way, I'd say take it to the seller and see what he says. I haven't read these issues before so they are not a known problem... Probably a hardware problem ?

This is not normal. Phone should cool down completely in a matter of minutes, not hours. If it's overheating to such an extent that you can't use it, it is faulty.

Nope haven't rooted.
I think that the phone is faulty so back it goes then. Tried ringing the company but they are not open on a Saturday so will have to wait to see if they are open on Monday now (but this is a Bank Holiday) but we will see.
Thanks for your thoughts

Just a quick update
Phone has now been off for 24 hrs, in a cold room, tried to switch on this morning still no luck cannot get past the HTC screens. Put it on charger and still showing led notification that phone is overheating. Boxed it back up, it is going back tomorrow and want a replacement
This is making me think do I want the One X with these overheating issues

I have the same problem about the loading, gonna try to remove the calendar widget; however Sense never crashed.
The heating your phone is experiencing is probably because it's faulty.
Sometimes mine becomes hot too, but in a bunch of minutes cools down.
lordjone, have you seen this thread? I was having the same problem and this fixed it. http://forum.xda-developers.com/showthread.php?t=1597880&highlight=loading

Well, I never had so many loading screens and with ARHD rom this problem is completely gone because the sense is entirely loaded in memory. Anyway disabling the background activities breaks the multitasking which i consider bad because i found usefull the ability to switch between apps.
Thanks for your answer

Got my replacement, had it a week now with no issues at all. Deffo something wrong with the last one, this one seems quicker and doesn't get so hot on the back where the camera is. So far so good. No screen flex problems......very happy bunny. Love it
Giving new phone is only a placebo effect. Because all HTC one x's overheat with high usage.
As soon as the CPU starts bursting more then 50% on only a 1000 MHz (max is 1500) then the phone starts heating up to over 53 degrees. At the point of 48 degrees reached in minutes the LED starts flaching red and green rappidly. when boosting up performance the battery will eventually reach 63 degrees celcius making it almost to hot to hold on to. Most apps crash when the 53 degrees is reached.
I havent tested a 100% CPU load on 1500 MHz but im guessing eventually the battery will burn, damage the unit beyond repair.
I have tested this on 3 different one X's from 3 different places, they all have this problem.
When you play tegra zone games like dungeon defenders it will take about 15 minutes to reach 48 degrees starting to make the led flash, warn for overheat. this game uses 50% of the CPU on aprox 1000 MHz.
I really dont wanna know what happens when you play a game wich uses 100% of the CPU on 1500 MHz...
This happens with and without charging. Wich makes me wonder.. Why they put in a CPU that uses so much power it burns down the battery and overheating it even on 50% CPU usage. This way there is absolutely no way the full power of the one x can ever be used without active cooling it. If you can use only 1000 MHz on 50% max what use is it to put in such a powerfull CPU, and games that will damage the phone.
For the record... Li-ion shouldnt be exposed to temps of 63 degrees for a long time. they will age in days, if not leak, explode or burn.
unbelievable that HTC made such a crappy device!
Not to mention that the battery dies in minutes when CPU uses full power.
to see your temp battery, cpu usage, cpu frequency and much more, download Cooltool in the playstore. its free. it can be custimized big time and root is not required
When a Li-ion battery is exposed to 40 degrees or higher the capacity will be reduced to about 35% a year. The one x becomes 50 degrees easily making the capacity drop even bigger. When using the phone allot above the 50 degrees will make you end up charging the one x multiple times a day after one year
