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? Thanks..

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 ^^

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.

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.

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

I'm not looking for knee jerk reaction to this video. This is a valid question from someone who's familiar with four corner testing which includes thermal testing. The correct behavior is to shut down once a temperature threshold is reached as seen with the Android and iOS devices. The WM7 device dangerously continues to operate beyond threshold.

No need to get emotional. This is a silly stunt video indeed but there is something to gain from it since it might expose the lack of or malfunction of thermal shutdown protection in WM7. A lot of people including myself keep their phone in their front pants pocket. Why wouldn't they be concerned f thermal shutdown protection isn't working and knowing that lithium batteries can be unpredictable when exceeding normal operating temperature?
Lithium batteries explode because of impurities in the electrolyte (or whatever it's called there) causing short circuits. This is purely an internal condition, and no thermal shutdown protection will save your gonads if it happens. So relax and get a life really.

Wrong dear. This thread doesn't apply to you if you have no family jewels.
http://computer.howstuffworks.com/dell-battery-fire.htm
"batteries could overheat, potentially causing burns, an explosion or a fire"
"If the battery gets hot through use or recharging, the pieces of metal can move around, much like grains of rice in a pot of water. If a piece of metal gets too close to the separator, it can puncture the separator and cause a short circuit. There are a few possible scenarios for what can go wrong in the case of a short circuit:
If it creates a spark, the flammable liquid can ignite, causing a fire.
If it causes the temperature inside the battery to rise rapidly, the battery can explode due to the increased pressure."
and we see all 3 devices explode at the end of the video (I don't know which version is linked, the one I saw yesterday had all 3's batteries swell and burst, and the flames flared up)

Nice detective work there... you quoted a laptop battery article.
This has nothing to do with Windows Phone 7 and is mere sensationalism to create a non-fact base, non-realistic controversy.
Btw if you create a spark or rapidly rise the temperature on anything, it usually catches on fire or explodes. That applies to 99% of everything on this planet.
I'm not sure if it really matters. As someone mentioned, all three ended up going because they were continually exposed to the high temperature. Simply shutting the device down wouldn't prevent that in this scenario.
Lesson learned: don't grill your phone.

you have to look the other way around ( that was external heating , if that was the way you would be already dead before the phone explode )
the os has to shut down when it get internally hot ( like a software bug , overcharging the batt , or a gps + wifi making the phone go hot )
and that is there , when I turn on wifi and gps and I am charging the batt the phone will reboot after some time (it reboot because it is on charge )
edit: I only think it is a bug that the phone reboot after a shutdown by overheating.
edit: ps it is WP7 and not WM7

No but really. The point is that the phone doesn't shut down if it would overheat on it's own. So, say that the phone by some reason should overheat to the point where there is a risk of the battery exploding.
i think if you phone gets hot enough to need to shut down...it's over anyway. Shutting down automatically isn't gonna save anything. There will be no cases of burnt faces like with the iPhone

It must be true cause I saw it on the Internet.
There are some who get it and the majority who don't. Unfortunately, the majority think that the HTC WP7 won while the HTC Android failed in the video. Or, that the added cost of thermal shutdown protection now built into phones is not there for a reason. Or, those that keep stating the obvious that lithium batteries burst when exposed to fire but fail to comprehend how the phone should've behave prior to reaching that critical point. These are probably the same people who will argue that a faulty smoke detector is of no consequence because houses seldom catch on fire or that you would know about it if it happened without a working smoke detector or that it would be too late even with a functional smoke detector. To each his own ballz. Let Darwin sort them out.

Alright guys got a really weird issue and I would like to know if anyone has had this problem before. So I was at the gym for about 2 and a half hours tonight,and I left my phone out in my car. I live in the midwest so temps are starting to get pretty low. About 30 here tonight. Anyways I came back out when I was done and my phone would not turn on. When I plugged it in it showed no led. So after about 45 min I pulled out my battery and popped it back in and magically my phone came back on. I flashed the new ziggy kernel last night and I use os monitor to keep it set to smartass but I don't know why this happened? I guess im just puzzled is there an issue with the battery in really cold weather or did the kernel cause it? If you guys could give me some input I would appreciate it. Thanks.

It's fairly well known that batteries don't do well in cold (thus why you see in car battery commercials "specially made to handle cold weather", etc. etc.) so that could be an explanation.
On a side note, LCD's don't do well either (think about it, Liquid Crystal Display). If you want an example, go in to Best Buy or something just after they open, while the building is still cold, and check out the LCD TV's; they'll all be lagging and fuzzy pictures.

I said overvolt not under. It would make it run hotter, so the temps wouldn't affect it so much. Put it in an inside jacket pocket, that tends to get my phone pretty hot on its own.
I live in Virginia and occasionally leave my phone on my car. Temperatures have been in the teens and single digits lately. No problems so far, but I'll probably be more cautious now. Hope it doesn't affect my battery in the long run.

Thats my fault, read your post quickly last night and didn't pay too much attention I guess I just saw "volt". Overvolt would not be a choice of mine though I would rather not risk frying my phone.
Ok so half or over half of most my days are spent in a subzero freezer unloading freight ect.. My question is this, am I doing any harm to my EVO by keeping it in my pocket while im in the freezer the phone does get rather cold while im in there im just wondering how much if any damage im inflicting on my EVO and should i try to find another place to keep it while im working?
no i believe you do not your body heat should provide some heat to protect it ..just remember if it gets under 32f your phone might get permanent freeze damage thats if you leave it in there. lol just keep it in your pocket
I would only worry about moisture intrusion. It may not affect the phone but it may cause your water damage tape to react thus voiding your warranty for water damage.
i wouldn't bring it in the freezer with you. keep it locked up somewhere.
As long as your phone is kept in your undermost layer of clothes. I can't see any reason why it would be damaged by the cold. I would imagine your body heat would keep it around forty or fifty degrees, which is perfectly safe.
Sent from my PC36100 using XDA App
I don't think the cold itself will hurt it, I would just be carefull of condensation that could form when it warms up.
Like was said earlier, it will probably be ok if you keep it in your pocket.
Most electronics dont mind the cold (those that use some kind of bulb are the eception normally). As others have said the problem is more likely the condensation or moisture that could occur from the rapid cooling or heating.
if it is under layers of clothing it should be fine but it is probably best not to take it in the freezer.

You should be just fine while in the cold. Lower temperatures, even freezing temperatures, will not impede the Evo operation; they may in fact prolong the battery life.
The problem is going to be taking a cold Evo outside, and having moisture condense on the phone. I would get a plastic bag, and put the evo inside just before walking out of the freezer.
I know the Evo is one cool phone but no reason to freeze it. Do you use it while in the freezer? What are you doing in the freezer?
I would recommend keeping it somewhere else if at all possible.
left mine on a box while lumping a reefer, -15°f for an hour, no ill effects, but if you do something like that make sure you warm it back up slowly and don't breathe near it, condensation will make you cry

I would be more concerned about how it would affect your health than the life of the phone. I had a BlackBerry 9700 that did that and I started getting migraines shortly after that. It kept happening so I called tech support and they told me that's not normal and they sent me a brand new replacement immediately. I would suggest you guys go back to the place of purchase and get it replaced. Or at least see if the other devices are the same.
Gotta melt that wax somehow. But seriously, give your phone a week to break in, maybe flash an undervolt kernel if you're willing and then see what's up. If the heat still feels uncomfortable, you might want to exchange it.

Is it heat from the earphone itself, or the heat from the back of the phone (next to the camera)? When I web browse/play games for short periods of time it sometimes become very uncomfortable to hold the phone.
