I'm running CM7 and Faux at 1.0ghz and find that my phone frequently begins to overheat and falter when using google maps GPS navigator while on long trips. The phone would begin to charge very very slowly or begin losing charge, and eventually would reboot.
I have tried underclocking it to 600mhz while on GPS and saw mild improvement but the problem soon recurs after about 1 hr. I do undervolt around 50mV to 100mV in all steps.
Anyone else having these problems?
Any solution? Should I further underclock while using maps?
Try no underclock? That may be causing stability problems under high load.
Try no underclock. Its normal for the phone to get hot under load. Also if you don't have the moto car dock it wont charge worth **** on generic chargers.

It charges perfectly unless I am using gps for more than an hour and the phone gets excessively hot.
I have previously tried not under clocking but the problem occurred.i only started underclocking as a possible solution to decrease heat production.

that's always happened. even since before cm7, I believe.
there's a thread around somewhere discussing this, I believe.

Hello. First of all, this is my first post on these forums and if anything is wrong with my post please tell me.
OK. So I have a stock kernal, stock rom rooted Epic. After using it for a while the battery gets to around 100°f and it feels really hot. Nothing out of the ordianary is running (checked using spare parts) and about twice this month my phone has shut off due to overheating. If anyone has had similar issues or a fix, I would appreciate your comment.
Thanks.

1st of all your post is fine. If a forum thrashed every 1st post, that forum wouldn't last long.
Do you have another battery to try?
Yes. I will test my spare out for today and check the temps.

It might be the kernal....my phone never shut off cuz of overheating, but it did get hot a lot even if I want doing anything on it. That problem wentaway when I flashed different kernals. Try flashing the mixup kernal and see if it still persists? That was the first kernal I tried and it went away, but idk if it'd still have the same efect considering when I did it, there was a no-voodoo and voodoo kernal version

I actually noticed decreasing my screen brightness keeps the battery heat 10+ degrees lower. It may not be true but I seem to notice touchwiz uses way more battery and makes it hotter. Keep posting fixes to the community!

I also will not flash any kernal because I always get my updates the night of OTA and I don't want to deal with flashing.

Same as my Epic get hot time to time when I charge it. Sometimes it charge just fine and fast. Sometimes it charge take longer than other and get real hot on the back of epic. It just hit 103 temp today. I do have extra battery and it act same problem. Is there some kind of firmware doesn't response to charging well? I was thinking going back to sprint and have them look at it.
Any ideas and suggestion?
Thanks in advance.
My peeve... kernel, people, kernel!

Mmm when I plug in for charging, and if it get hot, I unplug and wait for 15 seconds, then plug again. After that, it doesn't get hot and charging much faster.

I have all the stock stuff running and doing certain things (usually downloading will do it) makes it VERY hot to the touch. My Hero did this, but I had it running a custom ROM from almost day 1, so if you are worried that it is a custom ROM/Kernel doing this, mine definitely feels verrrry hot, although I haven't gotten the battery temp tester or anything, figure it shouldn't overheat since I rooted it but haven't changed anything else.
Currently at 102.2F as reported by setcpu widget while plugged in and using it for the past half hour or so. Seems kinda high to me, what's everyone elses experience?

Well when its plugged in it will be warmer than normal. Right now my phone has been on with constant texting and random other usage all day long and I am at 80.6 degrees
My phone stays in the mid 90s and early 100s with regular use. It only gets in the 80s if I leave it completely alone for an hour or so.
Sent from my DROID2 using XDA App
I stay mostly in the 80s and can get into the 90s with heavy use. Don't think I've ever passed 100, but there's a chance something like psx4droid could have pushed me up. I average about 86F.

Do you use the SetCPU profiles? You could set one to underclock the processor while charging.

I do, its set to 800mhz when charging. 600mhz if it gets above 104F regardless of charging or not. Leaving it alone on the charger for the last half hour the temp shows 92F. Just firing up Xda app and typing this out the temp has jumped to 98F in about a min of use.

Are you guys using SetCPU for profiles and overclocking, or are you just using it for checking temps and current speed?
These are the droids you are looking for.

I was using it to check temps for this but I use 2 profiles, which may help my temps (def helps my batt). The default profile is 1000 max, 300 min, on demand. The other is when my screen is shut off, 300 max, 300 min. I've found this has saved me a pretty sizeable chunk of battery. I tend to listed to music 7-8 hours a day and while it doesnt need full CPU it will use it if it gets the chance. Restricting the proc to 300 off has never caused any issues and I can get from 8am - 4 or 5pm staying over 70% battery I have the unstable apps overclock and used it for a while, but kinda came to the conclusion that I can't really justify needing to overclock yet as I never see any lag. I guess if I run into any lag at some point I'll prob clock back up to 1.3 or so.

I did overclock, but it ran way too hot, like 107F during normal use and didnt get below 100 dormant. 1gig is high enough to me. I have it set to underclock when charging or when below 50% battery or when above 104F.

Only other idea I have is downloading Droid Overclock and try running at low or ultra low voltage. Make sure to make a backup first. And try low before ultra low. Individual devices can be picky about a lower voltage and can go into a bootloop if it can't run on a lower voltage. Droid Overclock has profiles like SetCPU.

For some reason it was overheating bad, all I did was reboot the phone and it stopped over heating.....I do have the x99kernal and have it set to on demand 1209 max 245 min, that's not too bad is it?

Run my Shift all day at 1.6gHz, no issues. Once in a while with heavy use it will get warm. But not hot. My TP2 used to get really hot. After looking into it, turned out it was a battery issue.

What are we talking about for normal battery temperature vs one that I should worry about? I have serious battery issues and I am on my second phone because the 1st one wouldn't last more than 2 hours. I barely have any programs running and it won't last more than 4 hours. Thanks!

I had that happen to me 2 weeks ago at a baseball game... The phone was in my pocket as it always is, and the thing started getting extremely hot to the touch within minutes... Also using x99 with kickass governor, 245 min/806 max.
And I did the same thing to fix the problem as you..
Now if I can only figure out why I have no data at all today on the phone..
My girlfriend's Shift began overheating at a wedding not long ago. Was able to track it down to K9 Mail, which was stuck constantly polling the 3G connection. Even a reboot would only stop it for a while. Uninstalled and reinstalled K9 and all was well after that.
Same thing happened to me once when I tried the Pulse app I think. I was looking for a different RSS reader. It got stuck updating or something. I was sitting at work and my phone felt very hot. I noticed data was being transfered and checked the network usage using the *#*#4636#*#* and sure enough Pulse had downloaded over 200mb worth of data that morning on 3G. Once I removed the app it has been fine. I am stock rooted.
I didn't see an answer for this anywhere. What is the maximum temp this phone can safely handle before it starts getting damaged? It's starting to get warmer and i want to know when i should start to be concerned.

Be concerned when it enters the 100's(F), which it gets to while charger sometimes at high freqs and around 110ish. With normal use mines stays in the 90's or 80's.

I think it got up to 114 once and I had pulled of the battery cover and held it in front of the ac til it hit 85 degrees.

What freqs do you use on your MT4G? According to your sig you have MIUI, no?
That rom should run fine on Scary/Conservative instead of demonspeed or smartass. Temps will be lower with Scary/conserv governor enabled.

Odd..Unless the phone is kept in a warm or hot area, and is being used heavily too. Under 1GHz the temps should be fine, do you use the phone a lot?
mine hit mid 160's one day when my charger didn't stop charging (was at 99% for a couple hours) didn't do any damage, still on original battery and seem to get decent battery life on fusion/faux 0.7 kernal.

OMG i would be in a panic if i saw battery temp that high! I get concerned over 110.
my phone overheated to the point where parts of the touchscreen wouldnt respond. after it cooled down...everything was fine.
i got this when using assisted gps....

You're putting the HW parts at risk..Especially the CPU which can fail from those temps, this isnt a desktop CPU which has cooling to help the chip. These mobile chips shouldnt stay at those ranges. How can you even hold the phone at those temps? That's just crazy IMHO.

i realized that...i wasnt trying to keep the phone at that temp, it just suddenly happened...as soon as i noticed...i turned off the phone and pulled the battery.

I see, well do you use OC too or normal frequency range? I used to have a Sammy before the MT4G, and it would get really warm even w/o changes to CPU clock(But it uses Conserv. by default). These 1GHz+ chips generate lots of heat, I wonder if this is related to those bad EMMCs failing too...
My G2 tends to get worryfyingly warm when im using a bit more cpu intensive tasks. The cpu managed to get to 67°C when playing 3 races in NFS Most Wanted and managed to get 76° when doing Antutu benchmarks twice and it started throttling. And battery temp stayed around 40~45°. Idk, if this is supposed to be normal(please bear in mind my previous phone was HTC Evo 3D, which barely got hot ). When idling, the phone is just a bit warm. I'm running OptimusRs Pro V4.1 Stock kernel. Is this supposed to be normal for quad core phones or should I get it to service?

I know that, but it tends to get hot very fast, a couple of minutes heavy tasking and its already throttling
Sent from my LG-D802 using XDA Premium 4 mobile app
Is it really normal? I mean after 10 mins of browsing even the screen gets really hot..
see if you can check your kernel's cpu profile settings. could be that it's not allowing the cpu to idle when it should be. alot of times there are various profiles you can set it to 'on demand/powersaver/ect...' and this will change the behavior of the cpu's throttling.
Well now we're in the summer and the phone will naturally get hotter since the only thing that cools it down is the environment. If you're browsing under hot sunlight with 100 percent brightness then yes, it is going to get really hot.

its not normal bro. i have the same issue on all aosp roms and cloudyflex roms. my phone becomes really hot. if you give a shot at cloudystock 2.2, your phone wont heat up at all. try it out and be sure to make a nandroid before. just incase if you change ur mind and want to get back to this rom. i wouldnt recommend it though, anthing above 25*C for the battery is bad for its health since its a lithium battery.while the cpu heating up to 70*C is fine i actually use custom throttling to reduce my phone heating that much, i keep the throttling at 60*C
No it gets hot even at 60 percent brigthness while browsing. NFC, BT, 3G are off, i am using only 2 widgets, The top of the phone gets really hot... my sis has S3 and it never ever gets that hot, so do my old Huawei phone..
