My mogul randomly stops charging when Im on the phone or on the internet for awhile (connection sharing via wifi) . After seeing a blurb in the manual about how the battery will stop charging I decided to try something crazy (stupid actually,so dont do this yourself of mosture could damage your phone). I sprayed some cold spray on the battery. The phone suddenly started charging again. After 10 minutes,it stopped again. More coldspray and it charged again. Its pretty clear that the battery is overheating. I have a replacement coming this week,hopefully it will be better. Is anyone else having this problem?
It appears on further examination that this happens mostly when Im running wifi with the power setting set for max range and sharing the internet connection. It helps if I open the keyboard (seems to improve cooling). It seems to run pretty cool when Im just sharing over the cable with no programs running. I have also noticed the problem when playing games or running programs while talking on the phone. I see alot of people looked but no one else reports having this problem. Ill post some further information when I get the new phone monday.
Ditto
I have two Moguls in the family. Both had the same intermittent symptoms. We came to the same conclusion. Turn off Wifi when not in use and close background apps when not in use. This seems to be the fix so far. Will a ROM update help this situation?

I doubt it,unless sprint or htc decides to cripple the performance to reduce power. =( Seems it may in fact be a defect in the design. It helps to open the keyboard when your running wifi. I also found it helps if you turn wifi power down to minimum. (optimize for battery vs performance/range) and turn off bluetooth,as well as close all running programs and turn the display off. If and when we have an overclocking util available it may also help to turn down the speed of the cpu,at least if it has enough speed not to impact the network throughput.
I've always read the thread about battery life problems on here thinking "Thank **** mine doesn't have that problem" - luckily since I bought mine in December the battery has been quite impressive really.
But a few days ago it suddenly started losing power VERY fast. I'm talking about 10%/hour even on standby, so I undid changes I'd made recently and it made no difference.
Then I read through loads of other threads on here from people who had poor battery life on their phones to look for clues/solutions.
It seems that the responses are (understandably) fairly consistent, eg:
check for stuff running in task manager
remove changes recently made to the phone/uninstall recently added apps
make sure your data/wireless etc isn't doing stuff it shouldn't be
turn off automatic updates
turn down the screen brightness
check activesync
do a hard reset
upgrade your radio rom
etc
All of these of course make sense and are useful suggestions, but it seems there are a good few cases where doing these things don't help, ie you check out the different potential causes and none appear to be responsible. And in the case of sudden poor battery performance you can't point the finger at the rom/screen brighness/auto updates if they are only doing the same as they have been for ages without issue.
So is there a genuine case for the batteries just suddenly 'going weak'?
I've resorted to a hard reset on mine last night after assuming something had got corrupted hence why I could not find the cause of the sudden battery weakness.
But it hasn't helped - it's still dropping approx 10% each hour while on standby, even on a basic install, without even all the apps I normally have.
To me therefore it logically has to mean a failing battery if a hard reset does not help - or can anyone argue why that might not be true? The only exception I can think of realistically is a hardware fault with the phone.
Have ordered a new standard one anyway, and a hicap 'bulge' battery, so I'll post up if the new one cures it. Quite a few battery threads seem to have no conclusion, so ultimately they're not all that helpful in those cases.
How many other people have had issues like this where the battery life has rapidly gone downhill and a new battery has solved the issue?
Also, has anyone done any tests on their 'dodgy' batteries to see if they are indeed going bad or if it's the phone at fault? For instance (really basic I know) if I were to hook up a light bulb to the battery and measure how long it lasts before it goes dim, then compare it to the results from a new battery, would that be worth trying?
If that's the case it's p1ss poor that a state of the art phone can't even go 6-7months before the battery is junk!
I understand and appreciate that li-ion cells only have a certain number of charge cycles (like most rechargeables) but this takes the cake!
My old XDA orbit is years old, still has its original battery, and that has not deteriorated by any noticeable amount, so these shouldn't either.
See: http://forum.xda-developers.com/showthread.php?t=688496
and let me know if the new battery fixes the problem. I think the batteries might be crap and prone to failing early.
Thanks for the link - sounds exactly the same as my issue.
Hopefully the new battery packs will sort it but that's shocking quality control or product design/testing if these are failing so quickly.

Yeah right. But that has not solved the problems with the 6 month old phone.
What i have not read in the post of Cret is that you took the memory card out and see if that improves battery life. a corrupt file on the memory card causes a huge drain.
try because that also happenns suddenly e.g. after been connected to a computer and not disconnecting properly.
That's a damn good point actually - thanks. I had seen that mentioned in other battery threads yet somehow completely forgot to try it.
I will try and see whether it makes any difference - cheers.
If that should turn out to be the cause of the problem how do you resolve it?
To elaborate - I don't imagine you can easily identify which file would be the culprit, without formatting the card and adding the files back one by one and testing for the fault to re-appear. That's totally impractical, almost impossible with the number of files you can fit on a 16gb card, and the time it would take to carry out that process, so what do you do?
Or is it possible that simply copying them off the card, formatting it, and pasting them back would somehow resolve the issue.

Doesn't this usually result in filesys.exe spiking up to 100% (or just high) CPU usage, though? It isn't doing this on mine, although I'll give it a shot without the SD card. I would expect better battery life without an SD card in anyway, but nothing dramatic.
Cret, let me know if your new battery sorts the problem so I know to buy one myself!

What are you talking about? Again, you enlighten a thread with useless information. You can clearly see the OP has had the phone for 6 months (as have I) and the battery is failing (as is mine).
Plus, your battery must defy the laws of physics if it gets better day after day. Interesting.

What you can try is put the memory card in a card reader and run checkdisk on the card. see if that identify's any problems on the file system
beside of that it seems that the HD2 has problems with 16GB cards, at least quite a few of them. read through the posts.
Id suggest to collect more data about the problem.
The program BattClock lets you check the battery drain in mA. A normal drain for the HD2, with no processes keeping the CPU awake, is 4mA in standby, with only the radio being powered to receive calls.
So, since the battery current value isn't update instantly, right after you wake up form stanby battclock should be showing 4mA (max6-7mA or something lik that) fora few seconds. If that's not the case, and if the drain is way higher than that, then it may be the case that the phone for some strange reasons is draining more current than it should, and it's not a real battery fault.
I had a similar issue, solved it by disabling auto backlight. Set it at 30% and all good since then.
Well, I thought there had been a slight improvement over the weekend with this battery issue but this morning on standby the phone dropped 3% in a matter of 5 or 10 minutes on standby.
So I removed the mcirosd card and in nearly 3 hours since then it has dropped another 4%. That's a big improvement and does hint that the card is the fault, but it's too early to be sure about that. I've put the card back in to see if it begins to drop fast again. If so I'll take it out for longer and monitor it again.

Good idea. I wasn't aware that the phones had problems with cards this size. What about with 32gb ones (not that I can afford one!)?

I did use battlog briefly, but just to keep an eye on the current current amount in use and it was fluctuating a lot just with the phone awake but running no apps. Sometimes it after waking it the phone would show a low figure like you quote but other times not.
I haven't checked batlog out fully in terms of what it's capable of, but what would be great would be an app that can log the current use like that does, but at the same time also log a list of which processes/services/applications are running, then that could REALLY give some useful info.
Eg the log shows normal current use, then spikes upwards when a specific process begins to run.

make a request for this feature in battclock's thread
The author seems to be quite open to useful suggestions (I, among others, suggested the log-to-txt feature )
Would be a good idea - I like BattClock I must admit. Nice to have the taskbar info like it does.
Ok, later on in the day, it's worked out that it's used 35% battery in approx 3.5 hours of standby - pretty horrendous. Equates to about 10.5 hours (very roughly) battery life on standby. I've checked periodically during this 3.5 hour period and the drop has been steady.
With the card removed, it went 3 hours and only lost 4%, meaning approx 77 hours of standby time at that rate.
Quite a difference between the two.
So at this point it very much looks like there is a fault relating to the memory card.
I'll try some testing tonight. Mainly that will mean I'll first do a filesystem test as suggested. Then delete all the media files, cut the remainder of files and paste them elsewhere, format the card then paste them back, and see how it then behaves.
So it seems now that buying new batteries (and almost slagging off the HTC one) was slightly hasty, but they'll still be really useful, so I'm not at all bothered about that.
Try putting the blank card in, with nothing on it. Would be interesting to see how much juice it draws just having a card in there without reading anything from it.
I have the same issue.
My HD2 worked like a charm, only around 12% battery drain in 24 hours (I could carry it around on standby for one week before recharging).
Now - it sucks around 3% per hour. After one day, I'm at around 25% charge
At first I thougth this was related to Co0kie's Home Tab, but even after hard-reseting, it still drained battery as hell.
At the moment I'm running it without memory card (4GB Kingston) to see if this might be the issue...
I've run a CHKDSK on my memory card just in case, but the filesystem's fine. Any update, Cret?
Well, I'm sure mine was caused by the card, or at least a fault that related to it (ie possibly a file rather than the card itself).
Since I removed the card the battery life returned to normal, so I formatted it, and then copied some of the content back onto it again. It has been back in the phone for a little while now and has been behaving quite well. Basically for instance it's at 77% now at 10.30pm after being removed from the charger around 8am. I haven't used the phone much except to check emails a few times, read a few texts, and go online a couple of times/read RSS feeds a little.
So I'm fairly happy with that.
BUT - not having had the chance to use the phone much (ie mess about) since I formatted the card, I just found that the phone thinks there is no card inside it at the moment for some reason!
I removed it and the PC can read the card and its contents no problem but the phone cannot see it. The only reason I can think of for this is that I formatted the card as NTFS instead of Fat since it's meant to give faster performance, but is it possible that the phone itself does not support this format?
Since it's not working at the moment I'll have to try wiping it and changing it back to fat again.
Yes I have tried rebooting it also.
Next thing is th double size replacement battery I bought arrived the other day. The battery fits ok but the replacement cover that came with it does not fit properly at all.
The cover clips in ok on the side of the volume buttons, but no matter what I do it just hangs loose on the opposite side so I can't actually use the bloody thing since the battery will just fall out like this. Really not happy at all about this.
This is the one I bought:
http://cgi.ebay.co.uk/Extended-2400...eBatteries&hash=item5d2925ce91#ht_1862wt_1137
I think I will be trying to return this for a full refund since there appears to be a design flaw. Normally I would attempt to make something like this fit properly myself but if I failed then I'd have a piece of junk that I could neither use nor return so I think better just to return it without messing about.
It's a shame as the cover actually looks like it should fit perfectly, and seems to fit very well, it's just that it fails completely to latch in place on one side, as if the clip bit is not long enough perhaps.
What concerns me slightly at the moment
Just reformatted the card as Fat instead of NTFS and loaded my files back on and it works now.
So I'll update in due course once I've been using it loaded up again.
During the last week I experienced some strange behaviour on my HD2. I want to point out that in general I am very happy with it, but now I wonder whether my device is faulty or weather this is a feature.
What I have seen:
- my device had some sudden reboots when using it in my car, charging with car charger
- this happens only when outside temeperature is close to 30 degrees C or above
- it happens after some time (10 - 15 min) using Navigon or even just doing Bluetooth calls
- it usually stops charging the device, the LED is then blinking green & orange, then reboot
- I recognize that the device is very hot
- after cooling down it has lost the power settings
I found two other threads dealings with similiar effects
http://forum.xda-developers.com/showthread.php?t=707477
http://forum.xda-developers.com/showthread.php?t=627884
and now want to do some detailed anaylsis here. I installed BattClock (great tool!)
http://forum.xda-developers.com/showthread.php?t=612083
to monitor the battery temparatur and found the following:
- idle phone (office, not charging, 3G connect, push mail activated): 25 - 30°C
- phone in use (office, not charging, checking mails etc): 30 - 34°
- idle charging (as idle phone, plus charging): 30 - 34°
- phone in use, charging in car, summer temp 28°): temperuture rises up to 47°
The last case ended with a reboot, when coming up again the temperature was 47.1 degrees, green / orange was bblinking and charging has stopped. Before crashing the temperature raised from 33 to 47° within 15 minutes.
Can anybody confirm whether he can run the HD2 wíth 47° and above? I would like to understand whether I shoul return my phone under warranty or whether this is a feature. 47° is high - though I do not think too high??? I also got the impression that this issue is coming up more and more frequently with my phone and as the summer just has started this could mean I need to stop charging while driving. How to use navigation?
Any comments or ideas?

Well Hase,
I've seen this a few times in the past when driving running CoPilot, Bluetooth, screen bright and charging.
In the last week, with a new ROM base and significantly warmer weather, I've seen this with just having the phone in the car charging.
Very interested (and actively hunting) a manual underclock to see if it helps.
I don't think this is a defect, but it does happen.
I've noticed it too a alot during the NE heatwave in the US.
I'm waiting it out for now.
47C is not too hot though, although maybe there could be some kind of feature with the processor?
Yeah I've noticed it too. I was driving in my car running Bing Navigation with no problems for about 2 hours with the windows up and the ac on in my car. 10 minutes after I opened the windows when it was 101 F outside bing maps would randomly shut down and other apps would not even open. Closed the windows cranked the ac and held my phone in front of the vent to cool down and it went back to normal without even having to soft reset. Seems like a feature to prevent damage to the phone.
I would guess its some overheat protection feature with the processor, as its really the latest, which means sometimes it may get too hot ( you know, 1GHZ is really fast and thus may generate much more hrest than normal slower processors ) . Just like Intel's processors, which also shut off when the temperature rises over a certain programmed known "safe" temperature and reboots the computer, in hope that when its started again, it would be cooler. As for battery temperature, the cpu may be even hotter than the battery's temperature and thus it may seem that the phone shut off at a low temperature, but in actual, the processor is REALLY hot. And as its a mobile processor and its known that the second hottest factor is charging/discharging the battery, charging may be temporarily disabled until it cools down to a "safe" temperature to prevent overheating/buring out other components. But that's just what I think. Best to check with Qualcomm or HTC if possible as it may also be a defect in the phone. Hope this helps.
I haven't experienced any reboots but I have had problems with my HD2 locking up due to excessive heat.
Leaving it in direct sunlight means I'm unable to unlock the phone due to the lack of response from the screen.
Yesterday my HD2 was charging in its cradle and wi-fi was on. The device got hot and became unresponsive and I ended up putting it in the fridge for 10 mins which brought it back to life.
The HD2 definitely has an issue with high temps, the screen in particular.

Have you tried LeoCpuSpeed?
I have had this problam as well. It also happened with my Touch Pro 2 when in the car, sun, Copilot, etc...
My fix was kind of a lucky guess. I have AC vents that blow on the windows of the doors when it is on the defrost setting. I just have the windshield mount sitting kind of over the vent for the drivers window. It is not quite in a direct line with the window, but enough AC comes out of it to get to the device and cool it.
When I do this, it goes from a rather toasty to the touch to rather cold actually. Even with the rubber "case" on it it keeps it down to a reasonable temp, if not below, with it charging, GPS going, bluetooth stereo and WMP all going.
Since popping it into the airflow it has not even gotten warm let alone started the warning flashes and such.
Kind of an obvious one, but those are the most often overlooked so I figured I would add it in.

In fact that was my solution too. I changed my cradle using one putting the HD2 in front of an AC outlet and now everything is fine. Just make sure the lower part of the HD2 where the USB cable is connected is not covered by the cradle or any cover as this is the place where the cold wind has to blow. Battery temp remains well below 30° C, if driving longer distances even below 20°. I am not sure whether I will get too low? And I do not now yet what will happen in winter when we get it freezing cold and heating will step in.

Does anybody have tried underclocking yet? Would be good to now whether this could be an option too. Sometimes even using the HD2 on hot days (without charging!) gets the temp up to 38° C plus. Best thing is not to hold it on the lower part.
I am wondering that still only some people get this problems. Either everybody is ACed (not poss in my convertable) or the problem is only with some HD2 or some ROM. Has anybody noticed any other strange behaviour after an overheating occured? I noticed some issues during the last months which I could not yet connect to any other reason. I am not sure whether I have had overheating bevor these occured the first time:
- all of a sudden bluetooth connex to my car was not poss any more
- all of a sudden pocket xls application and the note application got very very slow
- all of a sudden POP connect to google Mail did not show any mails any more.
These effects did not show up the first time all together, they came one after another, one per month since March. And probably I have had overheating earlier without even noticing it

Hi, i have the same problem with overheating ... it stop charging when Battery Temperature reach 45°C. Battery PINS are all OK and clean
First : My Leo has Radio 2.11 (2.12 same problem)
OEM 2.10 (My own ROM)
Today Test : Go back to original ROM 1.66 (Radio 2.06) and my HD2 does not overheat ! Strange
I can see with PowerGuard that the charging current slow down when the temperature go up and reach max 42.3°C
Tomorrow Test : Radio 2.06 and my ROM with OEM 2.10 ... if do not overheat then i try with Radio 2.08 (more RAM ... TMOUS) ....
to be continued ...
Today Test with Original Firmware 1.66 and Radio 2.06 has problem too
Ordered new original Battery from Brack.ch ... when battery comes make new test to see if it's the battery or HD2.
Strange is that the battery is not so hot but the charge circuit of the HD2 is very Hot. (Hottest place is between SD CARD and SIM Card)

Hello,
I experienced the same sudden shut downs (not reboots) during the last days as well ("hopefully" only due to the very hot weather). And none of my POP3 account seem to work right now!
The internet connectivity seems to be okay, and of course I haven't changes any mail settings... but I cannot receive or send any mails. I get no error message when I try to receive mails but when I click on the new mail button my HD2 asks me to set up a new mail connection!
Any solution found to this problem?
Kind Regards,
DW!

On my side the problem is a bit different. POP3 seems to work fine (also no errors) but does not receive mails. Sending is o.k. And this problem is only with gmail, other accounts work like before.

I have now deleted 2 of my 4 mail accounts and re-installed them; the other 2 I simply have re-installed withour prior erasure - and this seem to do the job! Indeed I have done this more than once now, but 3 accounts now already received test mails... the 4th is a freemail account which I can only use every 15min. via POP3/IMAP...

But what was the outside temperature? I think the overheating has to do mainly with using the phone (gps) while charging in a hot environment inside of a car.
Just charging the phone shouldn't use the processor to any significant point.
Just my $.02.
I could not believe it what I read here, but now the high temperatures in Austria caused the same problems on my HD2 when navigating in my car. HD2 after 2-5 minutes blinks orange-green (no loading) and after maximum 10-15 minutes crashes.
Unfortunately I have to rely on navi-function for my upcoming vacation. No solution to place the HD2 in AC-stream in my car with this stupid original HTC-Car-Navi-Holder.
When driving in the heat of noon I don´t even have to switch it on, just mounting into the loading-cradle is enough to make the HD2 crash after 10-15 minutes, only 3G on, nothing else (no BT, WiFi, HSPA, no app running etc.)
Until now I was quite satisfied with the HD2, had no crashes or malfunctions so far, but now I am really fed up with this piece of sh.. and I don´t think there will be a hardware or software-solution (except swichting it off) since the HD2 is malconstructed.
This was the last time I bought a HTC product ............... Crap at a high price I can have with an iPhone too ................
For about 2 months since I have owned this phone it has given me nothing but crap. I always kept my G1 in my pocket and I always dropped it, even had it in water 3 times! (never had any problems) The G2 however if I kept it in my pocket, dropped it, or open/closed the keyboard repeatedly the phone would shutoff! Very Very disappointed at first. I missed many calls and text messages.
So How come NOW I can drop it, open/close the keyboard repeatedly, and keep it in my pocket without it shutting off?
I did a little investigating of the battery and contact points on this phone, it turns out that there is room for play with my battery. SO every so often the contacts would lose connection with the battery!
TO fix this I put a small piece of folded paper along the top edge of the battery opposite of the contact point to the phone, it made a more secure and snug fit to the contact points.
The battery does get Hot so I do not recommend this as a permanent fix as it is now a small fire hazard.
BUT, to this day I have had ZERO problems.
I am sooooo now with my G2 any questions or other comments please leave them below.

Meh... I don't think anyone else has this problem. If they did then they probably exchanged it.
Sent from my T-Mobile G2 running Cyanogenmod.
I have this problem.
I can't exchange it because I bought the phone on ebay.
If you search through the threads and on google, quite a few people experience this random freeze / shutdown where you have to do a battery pull.
I've tried flashing different roms, using only basic apps etc...
I don't think it's software related anymore, and if it is, it's too hard to diagnose. Many suggestions have been made, micro sd card slot, battery connections, software, weird app, different rom... I haven't tried removing SD card yet and my battery connection seems ok, it's pretty tight in there...
Don't know what the problem is and I wish someone could figure it out as it's frustrating to drop too much $$$ on a phone and have it act this way.
Random Reboots
I have a similar problem with my G2. It randomly reboots when its siting stationary on my desk or in my car.
This problem is made stranger though because it NEVER does this while I'm using it!! If I have it playing Pandora or Youtube - no reboots. But, like clockwork, if turn off the screen and set it on my desk, reboot... never fails... it will reboot 2 or 3 times then seems to be ok for a little while. Very annoying because I can't make or receive calls while its doing this.
Like others I've read plenty of posts on this but no working fix I can find. Some people say they returned their phone 2 or 3 times and still have the same issue. Some people say its related to signal strength but it does this will full bars or no bars.
I've tried custom Roms: CM6.1.1, CM7-RC1, & Virtuous 1.0.1 and the problem remains.
Does anyone know how to fix this? This is the only negative about an otherwise HOT little phone.
At least yours reboots! A lot of others just freeze (like mine)! And then you don't even know it.
I'm trying out another theory... Installed CM6 a few days ago. Had the same problem.
But I just started OC using CPU Tuner and the stock CM6 Kernel., the lowest option I have for clock speed is 700 something for some reason, so I just used that. So far, 36h, hasn't done it. I THINK, it might be related to the phone not getting enough juice for some odd reason - even on stock, so when you OC it and set a higher clock speed for idle, it might help. NOT sure yet but testing. Will post up if it "fixes" the problem for me.
My G2 was randomly shutting off a lot, usually right after I stuck it in my pocket. The solution? I exchanged it. The new one never does that XD
Possible fix for random reboot
I think I may have found a working fix for my random reboots. Credit goes to the OP.
I installed the Pershoot kernel and since then I haven't had a reboot and up until now it has rebooted like clockwork.
I'll see how it goes.
I had this problem while using the Red ChiChi/EVO batteries, but I believe my problem to be with the back cover. I might have dropped it and the cover got slightly tweaked, or perhaps it was the chichi battery, as it wasn't exactly a perfect fit. If a certain spot on it gets touched or pushed in, the battery loses contact with the pins and kills the phone. I have to pull the battery and let it set for a minute b4 putting it back in and powering up.
I used the same method, with a piece of folded paper on top for a while.
Perhaps its a different problem than the OP, but this only happened with my ChiChi batteries. With stock battery, it always seemed to be a good enough fit, and the corners kept it in place.
I ended up buying an extra stock battery for around $20, and now I carry 2 Stock batteries at all times.
Solution finally?!
I think I found the solution for my phone:
set OC profiles so the phone doesn't go below a certain mhz threshold.
On CM6 stock with CPU Tuner, it defaults to 700mhz lowest. Did not notice any increase in battery drain.
Uptime - 70 hours. Finally fixed!
//UPDATE: I did experience a freeze around the 100 hour mark, but so far that's the only one in the last week or so. In any case, it's doing MUCH better than before...
//OK I lied it still does it but so far just once or twice a week. Better than once a day.
So far there are apparently three problems/solutions:
- Micro SD slot loose connection / improper close - Check micro SD card slot
- Idle voltage too low, freezes phone / use OC kernel and set screen off speed higher
- Bad battery connection / manually fix
After many tries and diagnosing I think one issue is that on stock settings, the idle / screen off profile is set too low, which can freeze the phone (although I did have it freeze once while I was actively texting... not sure why). But 99% of the time it happened with the screen off. Hopefully it doesn't happen again, will keep phone on to see, but I don't remember it going more than 48h without freezing lately.
I have tried the following which did NOT fix the issue for me:
Micro SD check
Uninstall programs (skype, launcher pro, various others)
Revert to "stock"
CM6 "stock"
Checked Battery
Used stock battery / China battery
All those solutions still led to the random freeze / battery pull situation, but could potentially work for you.
2 G2's did the same thing. T-Mobile states known problem. After 14-hour shut down pulled mSDHC card and Sim and replaced battery which was drained in the off-state.
Solved problem and bought a Nokia N8.
Customer Service at T-Mobile and HTC is totally unconnected and unresponsive. Their answer wait for the FOTA.
Hope they don't send it to my Symbian ^3 jewel!
Was Shutting down multiple times a day - FIXED!
Hey Guys,
I've purchased my G2 from ebay so was not able to return it. So I've been trying to fix this problem for ever.
I have not found anything that works until now (knock on wood).
I installed the Cyanogenmod (cm_vision_full-32.zip) and updated my older CM version. The phone has not shutdown once in 4 days, which is a first.
Note: my GPS does not work with this version. I'm about to try a clean wipe to see if it will activate. I'm guessing however that the shutdown issue is 100% tied to the GPS so if I'm successful the problem will return. If a wipe does not work I'll try new radios.
I'll update any progress.

Caveat emptor.
I know. Live in Canada and only way to get the phone.
Me too, although my phone is at uptime: 211 hours right now
CM6 with cpu tuner with the settings posted above... basically make sure it never underclocks below 700 mhz.
I've been having a few issues with a couple of games freezing and have also had the phone get quite hot, particularly around the camera end. The two games I've had freeze up a lot are Fruit Slice and Pinball Classic, neither are spectacular graphics wise. Basically the games just freeze up and either I'm ejected to the home screen or I have to power off/restart. Occasionally I do get the "Force Close" box, but not very often, this contrary to what I would expect if it were just a normal bug related issue. sometimes it crashes after 5 mins or so, other times straight away. What makes me think it might be overheating is that once it does freeze up, it will do so again almost instantly if I relaunch. The rest of the phone seems okay in operation, I've run a few benchmarks and stress tests, all run okay so far. However (and it is a BIG however), once the phone has got warm, if I go to adjust my screen brightness I am limited to how high I can raise it and receive the following message: "To avoid overheating, maximum brightness has been reduced" (I've attached a screen print below).
Does anybody else get these issues or that message?
Got that "To avoid overheating..." message too while using Navigon Mobile Navigator inside my car (attached to charger).
In some other post I also read about a message like "To avoid overheating, the charging process has been paused", but this depends on the temperature of the battery only (I think).
Regarding the crashing games, that might be a problem of the game. But I had some crashing games, too, but I could not find a relation to the temperature of the phone.
Anyway, it could still be a heat problem.
In my opinion it would had be better for samsung to make the phone some mm thicker to better deal with heat and including a more powerful battery than just claiming to have the thinnest superphone.
Anyway, its still a great device.
Useful to hear it happens on other handsets, in fact I've now found a few threads talking about the issue happening on other models of samsung phone, such as the Infuse.
On the crashing games front, would you mind trying out Fruit Slice for a bit, to see if it hangs on you? If it dosen't crash after 10 mins or so I would think you're okay.
about overheating
i did experience it
when i left the phone in the car it became very hot and i get the same message

I'll try that as soon as I have it back (and if I remember to test), its currently at the repair facility because of a faulty camera.

Cheers, really appreiated. Just to update, I played it again just now, managed 3 games before it froze and kicked me out to the home screen; again no crash dialoge asking force close/wait?! I also checked my temp immediatly after it crashed, using Stability Test V1.5, it reported 31c, which dosen't sound too hot from what I've heard...who knows, cheers agian though!

sorry about the double post
Okay, I've been playing now about 15+ minutes without any problem. The phone doesnt get even hot, just a little bit warm. Using Navigon Navigator it gets a LOT more hotter.
So maybe you should try a factory reset? Or its a faulty phone...
By the way, I had display brightness set to Auto and I'm on german KE7 firmware.
