i've got the AC in my room on at 23*C and.. my phone got to 39*C haha..
tethering + charging + making a skype call on fring makes for a really hot battery.
Not sure about Celsius but Fahrenheit 109 degrees
109 = 42c, quite hot, the point is that the battery need to stay as cold as possible, there's a very good thread about battery somewhere but for some reason it doesn't seem to have been made sticky

Yea I was using the hell out of it on 3g and downloading while charging...
I'm trying to get it up to 150... blow the thing out my hands....
I don't know actual numbers, but I was in the car on a hot day... it was plugged into a charger, giving Navigation directions, and I was using the 3.5mm jack to play it through my car stereo... and for some reason (heat or cause of the 3.5mm jack) it started playing music and skipping all over. Was really annoying because I was nearing my destination and really needed to pay attention to all the turns it was giving me, and the damn thing was skipping every 3 seconds from one song to another, pausing to give a direction, skipping to another song, skip, skip, directions, skip, skip, skip, skip... directions.
I got where I was going, had to circle the block because of a missed turn. Picked up the phone and the screen did not respond, the phone was almost too hot to hold (wasn't in the sun any of this time but I also don't have AC). The screen seemed to respond but the whole system was very slow. Took over 10 seconds for a response. I had to remove the power cord and pull the battery. I left the battery out for 10 mins while I went inside my destination. Had the phone in my pocket and my pants were on fire. But I put it back in and it booted fine.
TL;DR Too hot to handle!
Mine got hot enough in the car for the screen to stop responding as well.
I believe I got it to 119*F at one point. But now it tops out at 113*F after driving with nav and music for about 30 mins.
I have no clue how hot it was but driving down to Baltimore and using my N1 on the windshield for GPS in a 95 degree day. The phone got hot enough that holding it hurt.
53.3C/128F with GPS on, on a 100F day
nexous one
my phone got 151 degrees F
and it was on the car doc charging in the sun and its fine
Ive got you all beat...
I was running eVils ROM OCd and forgot to scale it down for charging...
Running Google Nav and charging under the sun and...whammo!! phone shut itself down and would not reboot until it cooled off. I couldnt even hold the phone in my hand it was so friggin hot.
All is good now....

Thats intense. Surprised it didn't say "phone too hot" or something.
Mine has reached 45c. I have that at my threshold and setcpu throttles it down to 600~mhz.

Just curious what people do with their bricks when their sleeping..I like the idea of leaving it on, plugged in overnight next to my bed in case I get any emergency calls, but is there any possible wear/damage issues to the microdrive by leaving it on for extended periods of time?
About the Microdrive, no, not really.
But I couldn't vote in your poll: I personnaly leave it unplugged and in stand by (not completly shut down).
I am one of those who believe micro-leaking hurts batteries, even if they are supposed to be without memory-effect. So I don't leave it plugged, and when I charge it, I disconnect it ASAP.
That worked for me for all my batteries, which I kept up and in shape for a long, long time.
Thanks for the input Heartofdarkness, I guess I should have added another option to the poll at least one for none of the above. With work and everything, it seems like I am constantly in and out of my office with wifi, and bluetooth on. I'm fairly sure I would not make it thru the entire day on one charge, should I be charging it in spurts of like 30 mins? Currently im trying to get it as much charging time as possible, and unfortunatly thats in short bursts. I'm interested to see what everyone else does as well....... I guess it really doesent matter if the battery eventually craps out, at least its a replacable item.
My devicedoesn't shut down. It's always on 24x7. At night, it's my MP3 player if I'm not listening to my am talk back radio. It's also my alarm clock for the morning calls. Yes, my golf buddy can call me closer to the morning if there is any change in golfing plan, or just send me an SMS. Most probably, I still read and answer to XDA forum on bed until I get sleepy. Sometimes I download youtube videos and watch it before sleeping.
There will also be a scheduled backup that happens automatically at 4am.
Im option E: plugged in and completely off.
I suspect you would be fine if you didnt charge it all day. Mine goes on at 6am, gets a call or two and some browsing through the day (staying on standby otherwise), and by 8pm I have about 80 to 90% left. It then gets heavy browsing between me and my wife between 8 and 10pm leaving me around 30% at the end of the day. If I start browsing earlier than 8 Ill be left with 10 to 20%. Most of the day Im on a 3G/HSDPA network which uses more power than EDGE.
Have you tried going all day without charging?

Never happen for me. A single battery will not last the whole day for me. I use it so much that I normally also use a spare battery. When a battery runs out, I simply go the charger to take out the then fully charged one and swap them. So I never get caught not having any juice. If I'm in the car, then a single battery will suffice as the car battery quickly fully charge it.

Today I went 5 am to about 7:30 pm without a charge. But man was I hurting when I got to the car! Had to plug in right away, down to the short red bar on the top, I think that's 10%.
thanks for the responses
cool, I feel a bit better about leaving it on all night. even if its just standby mode, I need it there for the calls....and who knows maybe ill wake up and wanna check some news
On and powered - Its on the bedside table and runs SPBTime as a bedside clock. I use phonealarm to turn down the screen brightness to zero, volumes to 10% at midnight, then at 6.45, turn up the display back to 100%, volumes upto 60% and then trigger a connection to BBC Radio 1 via Windows Media Player to wake me up. And if that fails, SPBTime kicks off an alarm at 7am which I can't ignore and wakes me up.
I pretty much leave the thing running 24x7 and it doesn't spend that much time off the charger (Charged when by the bed, and charged at work - only between times that it doesn't get plugged in). I accept that the battery will probably need to be replaced at some point, my biggest concern is the backlight wearing out.
Well, I don't really use wifi that much, but BT's always on. And it is always in stand-by mode when I'm not using it. And currently, I think I could go about 3-4 days without charging it, and using it quite heavily as it is both my personnal AND professionnal PDA and phone and I'm on the phone A LOT.
My secret (I feel like a "Barbara Gould Woman" ) ?
- stand-by after 1 minute inactivity instead of the default 2;
- Pocket Hack Master + "disabled XScale scaling functionalities" + PHM scaling engine with specific settings, among which 204 MHz as lower speed;
That way, my Athena's about 98% of the time at 204 MHz, and still feels responsive because of my scaling settings.
Thanks for all your responses!
I've noticed it previously during usage (like on the internet while having MSN running, or while playing games)
but I just got off a phone call which lasted about 20 minutes, and the front (and back) of my phone was just too warm for me to ignore. I would have suggested that it was the heat from my cheek against the phone but that wouldn't explain how the phone was quite noticeably warmer than my cheek.
The backlight wasn't on (i doubt the LED backlight would cause much heat anyway).
Does the mega have any internal temperature sensors like PC's have? And any software to read them?
My previous phones NEVER got this hot on even hour long calls,
and mix this with the fact that at my work one of the PDA's blew up a few weeks ago (was the battery), it just makes me that more paranoid!
I am going to Hard Reset soon anyway as things started running a little slowly recently, I hope it will also stop any hidden processes that may be running in the background and overworking the cpu. But I would still like to know of any software

I think its pretty normal to heat up during long conversation. Their manual also says "Using any function for long time will heat up the phone", but only upto a level.

i've never experienced warming of the phone which is coused by operating it , well maybe just a lil utube watching for an hour but it was warm of my hands , i'm only worried when i leave it charging and after 15-20 mins LOL ! the phone is HOT i know that is normal , just sharing opinion
Heat comes from 2 sources in general external and internal.
External is from sun, your hands or phone in your pocket. On longer run this is not good for battery life.
Using navigation in your car during summer can run your phone real hot and feels quite uncomfortable! From a 20 min call it should not. But this is subjective.
Internal heat is caused when your processor has to work hard; like when several programs running and processes in back ground. You can check and kill them with task manager (FDC soft task manager) and batteryguard. Also soft reset kills most "unwanted" processes. A good indication for high level of processor activity is when your battery level goes quickly down.
Its normal mate, on mine when i use GPS for long time it does the same, processor works hard and battery gets hot.
Not sure if navigation alone causes your battery to run hot. Since navigation can run on 200Mhz processors and Mega processor has much higher clock speed it is overspecified.
The influence of phone close to windscreen and therefor impact of light/sun may be much bigger. When I run navigation (TomTom) in winter phone stays nicely "cool".
Not sure if it could help but once i noticed the Mega too warm and discharging instead of charging, after i connected it to the notebook via usb cable!
Rebooted PC and HTC and everything luckly returned normal...

Indeed a soft reset in most cases solves this.
i was using my phone for google maps yesterday and it was pretty hot.
the phone of course got even hotter since the screen was on and gps on and loading maps constantly
not burning hot but it could definitely use a fan.
i tried to locate some kind of heat dissipating tape or something similar to our silicone covers to put on the back of the phone
the only 2 things i can think of is copper tape, some kind of textured or wrinkle finish film as well.

Is there a windows mobile application that tells you the battery temperature?
I have a Nexus One as well and there is an Android App called battery indicator that will show you the temperature of the battery so that you don't overheat it and degrade your battery life.
Dunno if you can do this on Windows Mobile turn by turn directions yet, but when I am using the GPS on my Android Nexus One I usually turn off the screen since it still says the directions even while the screen is off. If I have to have the screen on (in case I'm on compact city streets with quick turns) I always make sure to hold the phone close to the air conditioning vent every 7-10 minutes or so to make sure the phone doesn't overheat. GPS + Screen on is a hot, Hot, HOT combination

WMWifiRouter shows the temperature of the battery, not sure about any others though.
Install BattClock form Zuinige Rijder, configure and You can monitor batt temp nicely.
Now in summer at temps over 30°C the HD2 gets really hot when on the car dashboard navigating.
At approx. 43°C it stops loading when in a loading cradle in the car (LED flashing orange) and very often freezes then.
Last time - after freeze - I took out batt and it was damn hot, reinserted, started HD2, temp showing 63 °C (!!!!!!!!!!), after some minutes froze again at temp 65°C
Contacted HTC-support on this issue, just sent me an advice for repair service, no explanation why this was not taken into account during development since it´s not a faulty device but a general misconstruction.
Works nicely when ambient temp below 20°C or cloudy sky.
don't all computers shut down at a certain temp???
Why would our smartphones be any different?
I dont have any issue's with my battery getting hot at all, running android though the processor gets pretty warm...
My gf washed my phone. It had like 7% or less when it went into wash. Full cycle.
I took battery out, put in rice for like 2 days, then I put it in warm place, on dash of car in sun for 20 minutes at a time in between delivering pizzas, ect....
I throw away the battery, and I use one of my back-up HD2 batteries. I use the external charger to charge it.
I boot it up, and it works! Touch screen, buttons, internet, speaker, camera! EVERYTHING. The screen after 2 days even looks perfect. No discoloration.
One issue.....
Battery drain. It loses like 2% battery per minute, even in airplane mode and screen is off. It won't last more than 40 minutes with moderate to low usage.
I plugged it into USB via my pc when it was at 15%. An hour passes, and now it's 3%. I confirm that it is plugged in, and the "charging" animation happens.
It's not the battery, because it's brand new.
What is the issue? Is it a short? Can I fix this? The phone is 100% working condition except for the horrible battery life.
I appreciate anyone's insight into this issue....
but here is almost the exact issue posted two days ago : http://forum.xda-developers.com/showthread.php?t=1226979
you might find something there
Hmm. I never heard of that. I do know when I got mine wet it acted really odd for several days and worked itself out over time. Example: I would click open app drawer and it would call a random person or I'd click the end button and it would start the calculator.
I'm thinking there could be damage left over from minerals that may have been left over from being in the wash. Do you use alcohol to clean it up? In the thread above I gave a detailed description on how I fixed mine, worth a read I think.Have you tried to make sure you don't have any of the battery pins bent? I know they have to match up though because your able to turn it on and use it but sometimes something simple like that is really all that's wrong. I'm curious to know now myself what could cause this.
Sent from my HTC HD2 using XDA App
I had my phone laying screen down on the couch partly under a pillow. I heard it vibrate so I went to pick it up and was shocked because it was extremely hot. So hot that the air around the phone and the whole couch around it was warm like a heating pad. I was able to pick up the phone but it was not comfortable to hold. Probably 120-150F externally and the battery was nearly dead.
So why was it hot? The voice activation seemed it picked up the catch phrase and was stuck at the "Ok Google" voice search screen constantly trying to process voice input. This isn't the first time the voice was accidentally activated and stuck either, so I will be turning off that feature or change the phrase so it doesn't activate accidentally.
I am quite concerned with the phone now because no phone should get this hot without shutting down or throttling to stop heat. I know many people have said this phone gets warm, but even just using GPS gets the phone alarmingly hot. It doesn't seem good for the phone. I only have a few days on my return period remaining, do you guys think this is a serious issue?
Note: I am running stock with frankenclark kernel.

Possible reasons the phone gets hot:
-An app(s) is running all the time... Solution: In developer settings there is a setting that shows which apps run in the backround, find it and delete it(the app not the setting)
-Problematic chipset... Solution: Get it serviced
-Kernel... Solution: Check what settings you have for your kernel, maybe you have disabled the throttling system
Hope I helped
