Today while I was in a store and my Defy was in airplane mode, with the screen off in my back pocket - it got super-dooper hot - so hot I felt it through a gel case and my jeans.
I took it out and started to take off the case to get to the battery in a panic but by the time I got to it, the phone had already turned itself off (which is nice if that is some kind of safety feature).
It is a genuine, factory original motorola battery so this is not a problem with a fake battery - it was made in 2011.
Only thing I did recently was upgrade to CyanogenMod 7.2 on the 17th or so but I have been using it since then without problems.
Overclocking options are not on, I'm running with the stock Cyanogen cpu settings.
Airplane mode was on, gps was on, but that's it.
Remember, it wasn't doing anything, screen off in my pocket.
Any ideas? This was kinda scary - glad the phone shut down.
Is there any history of defective batteries from Motorola?
Maybe some program was running and loaded the cpu which drained the battery. The heat came from the cpu and the cpu is just next to the battery.

Hmmm. Maybe, but when I yanked the battery out it was like a hot potato. Very very hot. I doubt the cpu could overheat it that thoroughly, more like it was being drained fast or possibly shorting?
I turn my phone on every morning from a cold start, the only program that was running was "MyTracks" (hence the gps being on)
I guess I'll keep an eye out for any problem reports with 7.2 on the Defy
It just worries me the times the phone is not in my pocket so I won't feel it overheating.
Is there any kind of app I can run that detects long periods of CPU use and shuts down the phone BEFORE the thermal trigger from the battery?
Does the Defy know it's own battery temperature by any chance? Maybe an app for that for the status bar?
I'm on CM 7.2 and my phone gets hot when I use 3G...

There's your potato burner Phone heats up a lot when GPS is on... On the top of that, you kept it in a gel case in your pocket on a (probably) hot day... What did you expect?
Thanks for all the ideas/feedback.
I turn the gps on every day and I have never had this hot battery problem before.
In fact it's on now while I test it and it's not even warm.
This was definitely an unusual event of some kind.
I just updated MyTracks in case there was some kind of bug fix.
As far as 3G, I do not have a sim in this phone (cannot afford any dataplan right now) and I keep it in airplane mode to keep the cell part off.
I found another similar report of the Defy strangely overheating the battery from last year:

I had this issue abt 2 weeks ago.... it was under my pillow and I went to grab it to check something n I had to let it go at once... I was on cm7.2, my guess was I had flashed so many Roms the day before and maybe the settings of CPU changed from 1 rom to another ... but did NT have this issue again so far .. now am on miui but never knew y it was burning hot zat day

Same problem here with cm 9; some days ago I found some stuck (blue) pixels on my device.no gps no wireless no data connectivity: it was the usb charger. It happened some months ago too and the stuck pixels disappeared but this time they are a lot....maybe I would put my device in freezer a night in order to recover my display ?_?

i'm still with the original phone (bought about a month ago). didn't change a thing, even not rooted.
a few days ago, was a hot day (about 32 c), same thing happen to me.
the phone was in my pocket in a rubber guard.
i guess it gets really hot in this protector... i took it down and waited a few minutes, then everything was alright.
i think this model might have some problem with overheating, so what i do is try not to leave it in the sun and take the guard on a hot day.

Thanks for your report, especially since it was stock - but I am sure it's not a regular "running hot" problem - because I have a very repetitive weekly routine and I've never had this burning hot problem before, never in a year.
Remember if they are in our pockets, the screen is off and typically programs are not running hard so the CPU should scale down to 300mhz, which should be very cool.
I installed this very basic and simple temperature monitor to put the temp in the status bar and so far I've never seen it go above 35c
http://www.appbrain.com/app/tempmonitor-lite/org.alldroid.apps.tempmonitorlite
It polls every 15 seconds which is all I need and no permissions.
Apparently the Defy only has a battery temp sensor and not a CPU temp sensor?
I'd like a better monitor with vibration alarm and a log but I am tired of all the overbearing apps with ads and "buy the pro version" nonsense and such.
Hi!
I used to have a CM7 with a chinese (really-really cheap) 1800mAh battery after the stock ROM (2.2 CEE); and I haven't experinced things like that. Mostly I measure the temp. with a widget (Elixir 2) and it was always below 35°C if I'm not wrong.

Hey. Does someone you know, what is the highest (read: critical) battery and HW temperature in this phone? I am a little bit scared when I'm getting even 55*C on battery when I am using it as a navigation connected to charger in a car. I know it's too high because when it's heating over 49*C it stops charging. My question is how dangerous is such high temperature for HW and Battery? Is it normal behavior?
I never had such high temperatures, and I live on a hot country (Brazil). Try to check apps running in background, or, if you are using 3G and charger, it can get really hot. But I think it's normal, since my phone reaches 45ºC while charging, and I don't use 3G.
with 3g my phone gets crazy hot. i once left it on overnight (it didnt go to sleep) and when i woke up it felt dangerously hot, musta been 50deg or something
otherwise, with wifi it just gets warm... still worrying though, considering none of my other portable devices have ever gotten this hot before... just shows where all of the battery life goes to! :S
i dont think its the battery getting hot though, it must be the cell chip. my batt temps are usually pretty low, and the batt itself doesnt seem to get hot. its just the panel above the battery that warms up
My phone got so high temperature (55*C) when I was using navigation. Moreover it was pluged to the car charger (but wasn't charging because of high temperature) and mounted to the window in hot sunny day. And I'd like to know how dangerous is such high temp. for the device.
I wonder if we have dud phones? my battery life sucks ass... bare able on wifi, but **** with 3g
Agree with scott. With prolonged use my battery doesnt heat up, just the panel above the battery (where the camera is)
And my battery life sucks too. Gotta keep it charged in the car for even short (30 min) trips with navigation

Try checking the manual (if there is) for operating temperatures etc.
I'm not exactly sure of how it'll affect the phone but it poses health problems due to higher radiations.
Try preventing this by ensuring all other (running) apps that you don't need are closed by using a task killer and all connectivity stuffs (eg. bluetooth, data sync) ESPECIALLY THE BACKGROUND DATA if you don't need it. Also, if possible try to refrain from covering the back panel (mainly the area near the camera) and allow ventilation to let it cool so it won't overheat.
What else I do is leaving the keyboard opened so there's even more surface area for it to cool.
The problem isn't just about damage, but that you don't want to be holding hot metal.
Yes it sucks but its a price to pay for such high specs packed in such a tiny casing.
My friend who owns Samsung Galaxy II has his phone heating up even more frequently and quickly, so we're not the only ones
Its annoying because we know its avoidable and shouldnt have been allowed in the final design by motorola
I've never seen such high temperatures with my M 2.
Highest was 47ºC while charging and playing a game. It usually sits around 35-36ºC idle, and 40-42º during games.

That's normal guys... Every device dying in a "few minutes" with 3G. And U know what? From my last 3 devices which I have been using to surf in the Internet with 3G (Moto RIZR Z8, Nokia N86, Moto Milestone 2), MM2 lasts the longest.

That's right, but every app just showing the battery temperature
Damn..
Yesterday my milestone 2 became hotter as ever, just above the battery (where the camera is, like newbietown). First I turned it off, but it stayed hot even then. After I removed the battery it became cool again.
But! Now my MS2 is completely dead...
It's really not turning on again, and charging is really weird (irregular flashin led). And my warranty is void because of me installing argen2stone I guess ..
Well, just flash a stock rom and they'll never know...
My phone is not recognized on my computer using USB . Can I still use rsd lite?
First get to bootloader mode: Power + Volume Up (or down) + Camera
If battery is too low you'll need to buy a relacement or a external charger.

Try taking it to warranty. Argen2Stone is so lightly modded, maybe they won't mind it. Anyway, you have nothing to lose now. And this really looks like a HW problem, not SW
Sent from my A953
Beginning of next week I will hand it in for warranty. I think it has something to do with the power circuit in the phone. Sometime i've used HTC chargers (1A) instead of the motorola charger (0,85A).. That could be the cause Hopefully they cannot see that.
I don't think that's a problem. I always use a Nokia charger, I find the original charger too short, the Nokia has a good lenght. And I never had problems with overheating. Also, 1A is the maximum current that the charger can provide, not the nominal [email protected] anytime
Rocking with my M2 and XDA app
2 or 3 days ago, while running VR13, I noticed my phone flickering green/orange LED lights while charging and also noticed it was hot. I looked up the problem and discovered this meant it was overheating. Ordered a replacement two days ago, arrived today. I charged it fully as soon as it arrived before turning it on. Eveything was ok, no overheating and to take extra precautions, I even flashed Ele's Gingerbread rom. Everything was working flawlessly until around the time I got home, I noticed the heat was going up again even though the phone was on standby in my pocket.
The battery life was low from a day of using it so it's charging atm. The orange/green light sin't flickering so it hasn't reached official overheating status yet but according to battery info, it's at 43.2 degrees celcius. I have no clue what's causing this, could it be the phone itself or could it be software related?
I didn't want to get a new phone till December or before ice cream sandwich rolled out so I hope I can fix these problems without getting a replacement. Thanks for the help.
Let me understand you straight - you had an overheating hero, you ordered a replacement = a new hero, and this one is overheating too? Without any obvious reason?
I mean, a friend of mine had an overheating problem cause of keeping his phone under a pillow during the night, but I can't see why yours would get hot.
Just a long shot, but maybe you got poor network signal, your hero tries to keep it up, spends more power, overheats.. had this a few times with my hero, while I was powerusing (net, sms, downloading something in the background), phone gets hot really fast, especially if it's overclocked.
Post some more info. Anything could be helpful. It's not like temporary overheating is rare. In the summer..
My tab was sitting on my desk in sleep mode. I picked it up and tried to unlock it and it seemed frozen for a moment, then let me swipe. It seemed fine after that. A few hours later I picked it up again and it was very sluggish and the back was warm and my battery at 15%. (it was at about 50% a few hours earlier) I rebooted it and it's fine, but I am wondering what caused it to get so warm. I know that happens when it's being used a lot but it was just sitting on my desk. There were no apps running in the background. Any ideas what could have happened? I haven't installed anything new in the last few days.
Are you running stock?

And we assume ICS (apart from stock)? But there are quite a few threads on the increased power-consumption on ICS (Stock and other). So might be some run-away process or service. What is the highest battery-user according to the device info? And how much? Has ICS gotten rid of the dialer goof-up for non-3G tablets?
P.S. Like the off limits (slap on the wrist) of the better half's tablet, same here :laugh:
Yes assuming ICS...my bad lol. It was more of a "tell me everything you've done lately" type of question. I have noticed increased battery consumption myself but that's why I switched ROMs today. If I lose a couple extra ticks on the battery in exchange for the performance I've gotten I can live with that
And yes I will lose whatever part of my body touches the wife's tablet. She's heard enough profanity in the last month as I got my feet wet hahaha!
Yes, stock ICS. Sorry for omitting that!
The highest battery user is the screen. I'm thinking maybe the tablet froze and I didn't notice it. Having the screen on constantly for several hours is probably not battery friendly. I'm concerned because it's still warm between the Samsung logo and the camera on the back. It's not hot or anything, just noticeably warm, and it's just sitting there charging. I'm not using it.
I have (or you can do it yourself) to delve in other threads, where they dismantle the tablet. Is it a P7500, or just a plain P7510? I thought that the 3G radio-part was about there where it still is hot (residual heat probably by now), but I can be mistaken. If this is a P7510, then I do not know what would be there at that location. It certainly is not the battery, that is much lower...
I will try and find what is about there, but other solder-happy soldiers must be able to tell you exactly what is located there.
Anybody?

A friend of mine had a similar problem with his galaxy s2 locking up and needing a long-press power reboot to get it working again on stock ICS 4.0.3. The culprit ended up being android os in battery stats, but the problem has not happened again yet. As for the warmth on the back of your tab, this is caused by the processor running at full speed for extended periods of time. If your screen is on, and you are interacting with it a lot, then you should expect the upper left back side of the tab to heat up and not cool down until you stop using it. This is normal... if it continues to stay hot for long periods of time after the screen is off, then you are probably not going into deep sleep mode because of a rogue app. If you are rooted, install better battery stats and CPU spy to do a little more digging. Good luck, I hope you figure it out and get your tab running the way you would like it to.
I figured out what it was. I'd seen the Ebook icon in my app tray and tapped it. It took me to the Samsung App store. I left immediately but that visit apparently installed "Samsung Push Service" which was taking 62% of my battery and causing 100% wake lock. What a POS! I uninstalled it and everything is normal again. Won't ever visit the Samsung App store again.
I froze that app. Ugly. Glad you worked it out!
I never cared able these heating stuffs ever, but for last 2-3 days the device is getting heated really badly, while charging it. The screen is so hot, and the upper backside around the camera section too, it's almost untouchable! The earpiece too! I checked battery temp and it's 41°C, so the issue is not there. How to check the CPU temp? And I think it's happening since upgrading to 4.3, because on 4.2, I never felt this issue. One more interesting thing is, the device is heating much more when the screen is off and the phone is charging, when I use it the device gets less hot, I think it's because the phone is charging at 1.9 amp when screen is off, and at 1.2 amp when the screen is on and the phone is being used.
Anyone else facing this issue? It's kinda scary.

I have heard of battery drain issues post 4.3 but think Samsung have released updates to fix it. I have had a similar problem a couple of times; I think both times are related to flashing ROM/kernels. On both occasions (today been the most recent) all cores (using CPU-Z to monitor) were been used at high loads and this obviously made the phone hot. Reflashing the kernel worked before but I have just changed LTE/WCDMA/GSM (auto connect) to WCDMA only and this had an instant effect on the cores. Perhaps that's worth a try.
I had this once on 4.2.2 , start charging at midnight and then early morning was extremely hot whith burn smell .
Are you using custom kernel ? maybe it's the fast changing feature !!
And yes I had this issue when it was on sleeping mode while charging , I disable it after that so it stay awake while charging and disable the fast charging .

I know I'm not alone on this one, I have to constantly cool down, it's totally intermittent and it's scalding....I hope it will be fixed soon and not just a myth. the folks at ATT said it had something to do with being more green. I think if an app is spinning in the background, it should be told to stop....
Mine gets very warm very quickly, but hasn't (yet) gotten hot. Certainly not "uncomfortable to hold" hot, anyway.
yeahh, i just received the phone and there are a lot of downloads an updates, but the phone is really hot. with a normal charger i hane no charging at all. the drain is bigger than than the energy from the charger.

I have been told by BlackBerry tech support the heat temperature flare ups could be caused by the encryption that is being done in the background.
Mine doesn't get to hot but it does get as warm as my note 5. I purchased egrip stickers from amazon to improve the grip and it has also helped with the comfort of the amount of heat you feel while holding the device in your hand and my pocket
I found a great app called "ShutApp" It let's you shut everything down that's running in the background. I have 117, It's running so much cooler now and the battery is lasting longer.
It's still not fixed got very hot in airplane mode plugged in at 100%, it dropped to 97 still plugged in So it must be something to do with charging.. It also just comes and goes as I'm working or watching a video...but sometimes under the same load it stays cool....
12/7 3rd party Camara apps are really cooking, and with short use maybe there should be a handwarmer app (lol)
12/11 I'm sad that this is electing my future non removable battery's life! ..at 100% I reboot in airplane with no apps running in background and plugged in it returned to 99% and started baking.. this is a power problem......
Yes my BlackBerry does get hot for no reason. All my apps are shut, last night i had it in my pocket and i felt it on my leg very warm. As I'm typing this right now i also feel it in the middle back of the phone. I really hope they fix this. As for battery life i am very disappointed, I thought it was supposed to be 22 hours and my lasts like 8 to 10 hours. I even got myself a Aukey portable battery charger and Aukey quick charger, it does charge fast like 1 hour and 30 minutes but it also drains quick. Apparently what drains it the most if being connected to WiFi. Really hoping they find a root for this or fix all these problems or I'm going back to Samsung.
the last update is solved this problem?
Serious hot spots have occurred in Airplane with minimal background while just working on a pic or document.. This is a serious problem and is leaning towards being a hardware issue.. Even though it helps to run an efficient system .. IT should be able to tell whatever when it is getting that hot to cool off....
I will hope to exchange it a third time But not until I know the replacement they give me isn't nt just another of the same....

The priv is the very first of its kind but here are some things you can do to cool it down
1: Turn The Brightness Down- most phones tend to heat up because the battry is pushing alot of power to the screen to make it brighter
2:Android: The Priv is the first blackberry not running the original OS; It's now running on Android Marshmallow which has a lot of animations and alot mor functionality so this could also cause it.
3: Replace The Battery: Yes I know it's the battery that came with the phone. I have 3 friends with the priv and when 2 of them went from stock battery to generic there phone did not turn into a brick out of the oven!
I hope this helped!

i had this issue for the first 2-3 days of getting the phone. disabled a few of the 'neat' settings ( wake on pick up, bb keyboard predictions, using swiftkey instead of bb keyboard, maybe a few others ) and since then it doesnt even get warm, like at all.. had it on for 20 minutes playing a youtube video and the phone was still cool...
Bought mine 2 weeks ago, it does get pretty hot (to the point of not touching it sometimes).
Only when I play games or snapchat, browsing internet doesn't heat it too much.
Especially when charging, so I try not to use it as much.
But the battery drops the same so it doesn't matter much, I just let it cool down and continue
Are you on any marshmallow rom ?
I haven't had any problems while using marshmallow.
