Random rebooting seems to be quite common.

    I've scoured the net while researching my problem and it seems that this is a common problem being caused by the radio board getting too hot through stress-use. Using GPS and 3G at the same time seems to be the biggest cause of problems.

    This may be a widespread issue that needs addressing. Could this be another Microsoft/ring of death?

    Do your own research and discuss.

    Ha ha. Actually, some Italian guy put a video on youtube in which he made the phone reboot 3 times by visiting a news website with embedded flash video. He then sat the phone on a bag of ice and eventually managed to see the while video right through to the end.

    There's your test. If I come across the link again, I'll post it.

    One of the early purchasers so I reckon I struck lucky.:(

    Don't wanna have to go to HTC cos I know it'll mean weeks without a phone while they "test" it. They're not gonna admit that its a common fault and give me a brand new handset, are they?:p

    Actually, HTC are pretty good with customer service......IF they find an issue with your phone they may well replace it. They did with me......

    I agree with the first post.

    Happens to me frequently if using the maps live wallpaper and 3g is on.

    I've had the opposite experience with HTC service. Phone in for repair twice (two different faults) 3 week delay sat waiting for parts, flat refusual to replace the phone and 3 times being told the phone was being repaired when in fact it was waiting 'another' part and hadn't even begun to be looked at.

    Compensation was a 4GB SDcard (the irony wasn't lost on me as it's the one thing we all have already).

    As for reboots, I've had about 3 in a total ownership period of 4 months. Two of which have happened after the motherboard was replaced last month. At least 1 of the reboots were when I was using GPS.

    I had the reboot issue to the point where I would have willingly hurled my Desire against the wall. I ended up giving in and sending it back to HTC, three weeks later it returned, and now I feel like making love to it, no problems issues at all.

    I went out today, using Google Maps, GPS, 3G and an in car charger etc It was faultless, got very hot reported as being 49.9c but no reboots. I just love this phone now it works !!!

    I've seen mine go up as high as 49.9C when using navigation and charging, but no reboots. Maybe that's as high as the reading goes. I wouldn't like to make a habit of running that hot though in case it damages the phone.

    I must have been lucky as mine was an early phone from March but I've had no problems.

    I hope mine turns out like that, it's been with them since Friday before last.

    I had it since the start of July, but only rebooting in the last two or three before it went back home.

    If I switched to airplane mode it would happily play music at work for hours on end.

    I have one of the first Telus Canada models, which I bought the first day it was made available here. I used the Maps Navigation app while driving from near Toronto to PEI last month and no issues with the phone. It does get toasty when running Navigation as the GPS is active, the screen is constantly on, and it's on the car charger. It gets warm when geocaching too, but never has it rebooted on its own. I've switched to a handheld GPS for geocaching as the batteries last 4-5x longer on a charge and it's more rugged and waterproof. But for all those things, and more, the Desire has been great...much better than the iPhone I had before.
    :D

    That seems quite reasonable considering I have had CPU's get to 70oc and GPUs get to 90+ with no ill effects on PC rigs.

    A PC has much better passive and active cooling (heatsinks and fans) that a mobile phone lacks. There is some passive sinking, but nothing compared to a PC. Having said that, mobile chipsets are smaller, run at lower freqs, and have lower TDP wattage ratings, so they don't need as much cooling.

    I haven't found any specs for the QSD8250 65nm process design which is the chipset the Desire uses, so I don't know if 49.9 degrees is too high or not. But I can say that if you feel the heat, then the heatsinking design is working. If you can't feel the heat in the case, then the chipset is not hot or it's not sinking the heat away from the chips, which is bad. Contrary to what many people think, if the heatsink is cold, it's not sinking the heat away properly - unless the chip is not running warm.

    If anyone knows a link to specs for the Snapdragon, please let me know.

    Unfortunately, the HTC desire only has 1 temperature sensor, which is the battery sensor.

    Not sure what you're using to measure the temp of the CPU, but on mine, even SetCPU is actually monitoring my battery temp. If you use spare parts and look at battery information, the temp should be about the same.

    Does the battery get hotter with increased use? Why yes, more use, more charge running through and out of it. The CPU may also contribute to the heat of the battery and therefore the battery temperature sensor indirectly. Of course being co close, they may be of a similar temp, but there is no guarantee.

    I'm not sure what the temperature thresholds of Arm 7 CPU are but we can't monitor them anyway. Just don't put your phone in the fridge or an oven.

    Lately my desire reboot after 1 or 2 minutes using any program, video and now phone calls. I cannot use the device at all when charging. I have spare batteries and must resort to using them at all times.
    HTC desire on TELUS 2.2, purchased late August.
