I've gone to using my spare xperia x10 mini pro now cause I've found while i'm out an about with my sidekick it will randomly get really hot an I don't mean like kinda hot i mean like feels like someone poured a cup of hot coffee onto thigh! The device hasn't been abused or dropped an its always had a tendency of getting warm at random it seams on all firmware versions. The only thing I can think of is possibly a issue with the phone connecting an unconnected often with the Bluetooth in my kia soul.
Now before you ask why I'm bringing this up now I had a none android samsung memoir befor this phone an it would get warm while GPS was enabled. Though in the sidekicks case it does it no matter what things are enabled or disabled x.x
So anyone else notice thier sidekick getting warm? with mine it seams like its something in the actual phone getting hot that in turn heats the battery up cause its around the DEL key on the keyboard.
are you running a 1.2 ghz kernel?
are their any wifi connections/bluetooth connections or any data transfer in the background that could cause your phone to clock itself @1ghz or above?
do you have any apps that run in the background (beyond the stock rom) while you are not using your phone?
your cpu could just be getting hot from background app usage while running @ the max cpu clock speed or overclock speed if you're on a overclock kernel.
The phone has never been overclocked an its done it totaly box stock with no wifi,gps,bluetooth activated an no data being used an has done this aswell with any connections enabled or doing transfers over blue tooth though since day one i do get a FC buzz when it first starts up but doens't say whats FC'd also notice when its getting hot that the battery amount is getting discharged by 10/20%
Hopefully it never got overcharged, or undercharged...
Have you ever turned it on after it turned off from 0% batt (or done this multiple times), I know that Lithium Ion batts have issues (I think it is 15% on the battery, but as 0% to the phone) if they go below 15% (0% in the meter) they will loose the ability to work correctly from then on out...
Calibration ever done at "NOT 100%", so it might think that 100% is 90% (or more) and try to keep charging?
Do you not charge it every night? (I have always charged all LiIon batts every night [mostly] and I have yet to run into issues with ANY batt.)
best to charge the battery with the cover off takes heat away from it
the odd part is that the battery never is warm while charging stays at normal operating temp for a happy battery. Now what I'm thinking is the battery is actually getting warm from something in the phone itself an transfering the heat towards the battery. An this phone has gotten warm like this even when it was less then a month old on box stock none rooted firmware of all types x.x

Hey guys,
This last week has been absolutely brutal in the northeast us. We've had high 90s pretty much everyday. [Especially in the car] my g2x has been suffering from "random reboots" running fauxs 1.2.8 and kernel 0.3.2. It was a new phenomenon, I thought it was the DS kernel I had rather than CM7, but all that did was affect battery life.
I finally was using my device when it decided to "turn off" and the screen just kept turning off ( less and less time being on, fractions of seconds.) Then it just stays off and the battery temp reads 100+° at turn offs.
It requires a battery pull to turn back on ( and I guess turn off) but the heat doesn't seem to come from the battery, but behind the camera, im thinking processor.
Could it be from the OC/UV kernel. I had on? It's on standard now.

OC'ing can easily overheat/fry the processor (hence why there's always large warnings around it), especially if the kernel hits a race condition or similar.
The phones are passively cooled. and the radios in the phone heat up the phone when used heavily. I have not had anyphone that didnt get extrememly hot while it is using the radio when its in above 80 degrees ambient temperature and overclocking would just add to this. luckily most have a feature ot turn off the phone at a certain temp to protect the hardware. But I dont think this is a specific g2x problme my old droid does the same thing.
I took mine to a pool in Vegas. It was probably about 90 degrees. I had it under my lounge chair shaded listening to music. It had a heat stroke after about an hour.
I understand why/how overheating can be caused by oc but honestly if its not running at stock (or benchmarking) I have it set to 800mhz by default- its still fast as hell. It hasn't overheated in the last few days, but the problem was that even if I don't use it, it'll overheat.
I use juice defender to keep my radio off when the screens off, so I can't even lay blame to that.
I haven't really dove into undervolting, but in theory wouldn't lower voltage equate to less residual heating?

mine does this running stock. Mostly when I have the charger plugged in and am still doing something. It will be taking a charge but the batery level will still slowly fall, once it gets below a certain point it gets really hot behind the camera and the screen starts locking and unlocking. faster and faster until you finally have to pull the battery and let it cool down a while.
YES!!!! I have 2 G2x that do this, and a guy at work has one. All stock phones, and can be doing NOTHING - gets hot near the camera lens, and LOCKS!!!! Have to pull the battery. I pull the battery for 1 second, re-install, and G2x works fine. I know of 3 G2x, and all do this. I can't believe I don't see more of this on this forum. T-Mobile has a "discussion number" on this: 265747. LG claims ignorance. I'd love to know how to "fix" this. I'd also like to know if GB fixes this.
The occasional re-boots are live-able - this lock up is NOT.

I can verify this is an issue with my phone as well! It was happening all the damn time in both stock Froyo and EaglesBlood Froyo, but as soon as I went to CyanogenMod 7 RC1, I haven't had it happen once.
And to those of you who haven't had this happen, it's like the Sleep of Death + your phone gets REALLY hot by the camera lens and it keeps draining the battery and putting out TONS of heat until you do a battery pull. It brought my battery from 100% to 25% in like 30 minutes of doing this.
But CM7 seemed to solve the issue. No more SOD+heat!
This problem has been driving me absolutely insane. My wife and I both got g2x's at the dame time (new from tmobile), and hers rarely does this, while mine does it continually. I was wondering if it was related to the case we have - but we both have the same case - the speck one sold at tmobile.
My wife and I both have the little rubber buggy baby bumper condom case thing that does cover the back - that would reduce heat dissipation. I often carry mine in a belt case that came with the phone from CostCo - she almost never uses that case.
I am getting tired of having my phone getting hot every time I use it for more than 5 minutes... You charge it - it is hot, you use it - it is hot, you lock the screen and put in in the pocket with some apps running to it - it gets hot. The only way to keep it at a normal temperatures, do not use it at all....
I originally blamed it on 4G LTE - so i forced it to 3G for a week without any success... Since it does not heat up on during phone conversations, my theory is that it has to do either with the processor or possibly the battery, that overheats during charge/discharge...
Coming from Fascinate - this has never been an issue to me which makes me miss it a lot ....
I have two of 2 weeks old Charges (brand new ones that I unwrapped myself). It tells me that this is not an isolated issue with particular phone or a battery. I experienced it on a full stock and voodoo kernel.
To all guru's that are out there - did you find any solution to a "hot potato" Charge?

Still could be bad hardware. The only time my Charge gets hot is when it is on the 1amp charger or if I leave the screen on for a very long time. Like 40 minutes or more.
Other than that mine is cool all the time, 4G or 3G

mine doesn't get CRAZY hot but here's how you can fix it, flash the OTB kernel and underlock/volt to 800mhz, the only thing that will slow down is your browser when playing videos(like youtube) through it. It will solve your heat problems, it definitely solved mine for the 2 weeks that i was underclocked.

Is it the processor or radio?
Every HTC Android phone I have had (G1, MTS3G, G2, MTS4G) gets hot at the bottom of the phone when I am online with it, regardless if it's network or WiFi...they always get warm when I am online. Today every time I touched my phone it was warm at the bottom, as if I was online. So I force closed pretty much everything, especially things that may transfer data...but it stayed warm and my battery started was at 75% after 3 hours of pretty much no use. No calls, no internet, no texts, no games...just me shutting down programs. So I turned off my network. After that, the phone cooled off and my battery lasted longer than usual. But even then it's almost dead already.
Either the processor is simply too much for this battery, or there are things running in the background that are constantly streaming data. Either way root needs to come quick, or this thing is going in the box and the G2 is coming back out.
weird that only happens while i'm charging and doing something it at the same time.
Yeah, i've noticed it too. I also noted that it's right over where the battery itself is.
I chalk it up to how quickly the battery is being used, and these types of batteries aren't so great when you drain them fast. The inefficiencies start to show and they heat up.
I think getting a larger capacity battery, like the ones being talked about in this thread, might help lower the temperature. If the drain remains mostly constant at high output like that, spreading the load over a larger discharge range won't tax the battery itself as harshly.
Anyone with a higher capacity battery then stock notice it not getting as warm?
I've had my nexus s (9020a) since late November (bought it used, in execellent condition.) While battery life was never awesome, it was at least bearable - until last week. I'm now unable to get more than 6 hours on a battery with super-minimal usage. For instance, today, as of right now, I have 5h 58m 57s (at 7% battery left) - the top "user" being the display (32%) with a "time on" of 17m 30s. Even when I power the phone completely off (not the screen, literally powering off) - say for a half hour or so - when I power it back on I lose substantial amount of battery.
Some other details:
Currently running stock 2.3.6 rom (since yesterday), but rooted.
Previously was running stock ICS (flashed the tmobile 2.3.6 ota, then ics, then the att radio) - was fine for the last 2 months
Tried brand new battery (not a samsung, but Anker) - no difference
Tried several different charges, and charging via computer
Have wiped battery stats several times (and done complete resets/formats of everything in between swapping roms)
Phone used to always top out at 95% when charging - but now will go up to 100%
This behavior started up when I was on vacation - a few hours after landing in SLC, UT. I do recall a sudden crash / reboot of the phone before the problems started - but I have gotten random reboots in the past. Was running ICS at the time. I thought maybe a poor signal was to blame, but again, the battery would drain even when the phone was powered off (or in airplane mode.)
I'm not sure what else I can/should do - short of calling Samsung. I'd think if it were a hardware issue, it would fail to charge completely. Does anyone have any other ideas or suggestions?
Thanks in advance!
Sounds like something external is draining the battery. I've seen many cases with a magnet on them drain the battery very quickly, or possibly excessive heat. If not i would say it's some kind of hardware problem.
Does not sound like android chewing it up.

I don't have a case on it - just a screen protector. The battery does tend to run in the mid 90s fahrenheit (according to battery status apps.. though I think I have seen it as high as the low 100s (maybe 102?) - but I figured that was normal.
Another weird behavior I should mention: sometimes when I power off and on while charging, it will cause the battery percentage to jump considerably. Right now, two consecutive on-off-on cycles (within the span of 3 minutes) caused the battery percentage to jump from 36% to 44% to 57%.
Heats normal. Not sure what it could be to be honest. Maybe grab a can of compressed air and spray around the back, maybe dust causing a short or something.

Thanks, will try that
Sent it back to Samsung for "repair". As I suspected, all they incompetently did was re-flash 2.3.4 and say "passed all functional testing". Phone is still hosed and completely useless as-is.
(Fully charged, overnight - less than 8 hours - went down to 17%, with no apps running, no google accounts, no sync, no background anything, no screen time, no wifi, in airplane mode)
Samsung really is hopeless. Going to try again with them? Whatever you decide, best of luck. Hope it works out for you.
what is the mv reading when the phone is fully charged? Fully charged should be around 4200mv

Trying again, but not optimistic. I talked to about 4 total "customer support" people today.. at least got them to "upgrade" me to 2-day shipping for sending back and forth instead of the normal ups ground.
It is so foreign to me - coming from Apple where, under warranty, they'll pretty much swap problematic devices out for new ones _in store_ on a dime. I pretty much begged Samsung to just send me a refurb unit to replace it with but they said thats "not their policy."

I don't have it with me (send it back for round number two) but I am fairly certain that is around what it was reading.
The thing would even burn through battery when powered off, if the battery was still left in. Taking the battery out = no drop. It has to be something hardware.
hi..
when playing ingress my battery can reach up to 50 -52 degrees celius, while my CPU can go to 60-70, sometimes the phone shuts itself down.
are there any packages i can use with heat sink or something similar to vent off the heat ?

Is your phone in a case? Many of them would act as insulators, trapping heat inside. Running without a case will probably help it stay cool. Also, I think the unit will run cooler with the keyboard open.
I've got nothing to productive to contribute to this conversation other than I've noticed this too.
The phone will be unbearably hot to hold. I've tried to see if any application were running in the background, eating up resources, but there's nothing consistent that I can report. Some days my phone will go all day long without any problems. Other days, the phone just drains the battery really fast, gets really hot, and displays an over-heating message. The only thing I've been able to do is shut the phone down and remove the battery and wait a few minutes until it's cool to the touch, then put it back in.
Same and this is a relatively new issue.

I used to play Ingress about 6 months ago on my old Cliq2 and I can confirm it uses a lot of resources. My phone used to crash all the time due to, I guess, not enough memory. And it was rooted and fully debloated.
You won't be able to easily extract the heat from inside your phone. One thing you could try is to play without the back cover. Just tape the battery so that it doesn't fall. You'll have to be careful to not damage anything that will be exposed on the back though.
Another thing you can also do is slow down your CPU using some app. If using CM 10.2 it's very easy to do. Go to the performance settings and choose a lower maximum frequency.
Finally, the last idea I can offer is to tether your phone and play using a tablet. The best setup I've seen is some guy having a tethering cell phone in a backpack, with a large extra battery connected to both the cell phone and the tablet he was actually playing from. He could play all day like that.

Well we're officially supported on CM so not bad I suppose ;p
CM-10.2 will run cooler than stock due to use of AVS. This dynamically adjusts the CPU voltage levels to reduce power consumption and heat, even when the CPU is running full out.
Also note that not all CPUs are created equal. Some require significantly more power to run stable than others. If your bootloader is sending sec_pvs=fafa as a kernel commandline argument, then it means that somebody up at samsung or qualcomm has determined that your CPU needs full on maximum power, which basically means that it will be un-nice on battery and heat. PERIOD.
To reduce heat levels, run it connected to a >= 1 Amp wall charger (to keep it from sucking off the battery -- note: NOT a USB port), keyboard open (more surface area = more heat dissipation), and BACK COVER REMOVED (reduce insulation).
I've noticed that the phone can get warm, but the only time I've had overheating issues was either a) during a long rsync-over-SSH run on Wi-Fi, or b) phone left in car on a hot day with GPS and navigation (either Google or Sygic) running. The latter was fixable by running the air conditioning.
In my experience, it has just been hot enough to shut down charging, not the entire phone.
I've just ditched the case, mostly because the plastic tabs don't work very well. I'll have to see what this does to thermal behavior.
