General Warning: Overheating!

Just a warning to all using the FreeX10/other 2.2+ performance ROMs that I experienced is the overheating of the device. This may only be me, but I'm posting this just in case.
Quick details of my X10:
Flashed to FreeX10 Beta #4 last night.
Used SetCPU to set scaling to Performance and minimum clock speed @ 998MHz.
Using the 3G (build.prop) enhancement modification.
I have a rubber casing around the phone.
Usually connected to WiFi.
My phone has been on since last night and has been charging for most of the time since then and now.
Just then, I decided to turn my phone off a couple of times. I did not notice the heat from just holding it. I was browsing here and read a thread about removing the battery, so I just did that for some reason. It wasn't until I opened the case when I could smell the smell of melted/hot plastic - it was coming from the battery. I immediately placed the open-phone and the battery in front of a cool fan, the battery and phone both started to cool down and the smell disappeared. I couldn't find any liquid/melted plastics anywhere on/in the phone, but I could definitely smell it.
Just a general friendly warning (that can't hurt). Not sure if it's documented or not, and whether this is only Froyo or below/above.

Used SetCPU to set scaling to Performance and minimum clock speed @ 998MHz.

what's the point?! if it is to overheat your x10, mission complete

Why using setcpu? I use the same rom and it runs like hell without setcpu. No overheating neither...

nytral is right. You set the CPU to run @998Hmz at _all time_ so it'[s only natural that the device/battery overheated.

u have managed to make a perfect guide on how to overheat the phone...
u push all the components to their max working capacity (full cpu, 'enhancement' of radio) and on top of that u keep it enclosed in a rubber casing...
bravo!!!

Sorry, Min is 245. Not 998.. :-/
And I'm pretty sure the material of the casing (rubber vs hard plastic) wouldn't matter, but would contribute to the heating. I'm sure that a lot of people would use a case of some sort to protect their device.
The only reason why I started this thread is because I was on a ROM not too long ago (a couple of nights ago), which has exactly the same settings and modifications, except, it wasn't running Froyo - it was running Eclair. And since I installed that Eclair ROM, the phone has only been turned off once (with the battery removed, about a couple of days after installing it and it being on and charging pretty much 24/7) and has been charging pretty much non stop.
The only difference is it is using Froyo instead of Eclair... Hence why I thought it'd be best to start this thread.

LOL, now this is n1 example of a person who didnt read before he flashed
Solution dont whipe data...

lol nice overheat guide
i'm using setcpu to scale it to powersafe and max @512 Hz
and when the screen is off it's max is set to the lowest (256?)
and when i wanna play games i always set it to min 256(?) and may 998 ans performance
then my battery won't drain so fast

nice overheating guidelines

Do you guys actually see a difference with setcpu? I have used every option available and nothing ever got slower or faster for me.

Yeah I'm running 2.2.1 and my X10 is no where near hot. well, at least in temperature because its a hot-sexy phone ;P
Nice overclocking there though X10 watercooling systems now in development, expect another forum branch to open in XDA in the next coming weeks.

To my understanding the 2.6.29 doesn't support overclocking so setcpu shouldn't make a difference at all. The rubber case probably contributed to the heat retention but the heat likely is from the constant charging.

Try the JuiceDefender app and set it to turn off wifi and data when your screen is off or unless certain apps are visible, helps with battery and stops unused functions while your phone sleeps.

Phone doesnt overheat, if you use it right.

Useless topic!!
Sounds like a guy (not saying names) that Z tells to remove some files from "some" roms he was taking without permission, just trying to desestimate Z rom.
Beta 4 runs very well, theres no overheat.
Sorry for my bad english!!

I have installed cm6.1. 3 v4. 3, its a fab rom.... but charging is the main prob... even if i charge for 2 hrs continues it charges upto just 60% and it becomes very hot..... any solution for this......

Try charging the phone while its off. Ive heard people say that their phone wouldnt charge past a certain point but after charging it whilst off it returned to charging back to 100 percent. I bought a new usb cable for my charger after the terminal end into the phone became deformed and my phone now charges ~3x faster but ive never had it get abnormally hot.

Hmmm... i set cpu to 998 when running emulators, otherwise its just ondemand. Using freex10 b4 for a fortnight high use frequent charging added 3g build prop lines, got no overheating issues.

Its funny that anyone with the know how or has supposedly read these forums continue to pay for (or pirate!) apps that have no effect. WITHOUT UNLOCKED BOOTLOADER AND CUSTOM KERNEL OVERCLOCKING APPS HAVE NO EFFECT! Check the overclock option in JuiceDefender, this option is not supported! The developer of the app has apparently left out any notice that it doesnt work with our kernel so they can continue to make sales.

Yep, very normal. However I did find that using GPS really heated things up... next hottest is games

probably using that particular GPS software, not just GPS antenna by itself?
does it heat up if you just display GMaps with your location, without doing anything heavy in GMaps? Because I did not notice that much heat coming from using light GPS apps. Gaming - yes, some of those games are killers.

I am using Navigon software. I played Angry Birth and the same,phone was hot after 5min. I know is normal that phone is warm, but this is not warm,but hot.Galaxy S was cold compare to S II.
Sent from my GT-I9100 using XDA App

Of course it's NOT normal. Might be normal for SGS2 but not for others. as I've said on another thread, Navigating with GPS driving it got to 60C, you could slowly cook an egg at 60C.

Mine doesn't get especially warm, It gets well 4-5 degrees warmer when I browse the web or watch HD movies

It's think it's high screen brightness in combination with SW (high CPU load)!
Mine is never warm if brightness is kept below 50%

My screen brightnes is 0%. It is hot at the top where is CPU I gues.

How many degrees celsius is taken as very hot on the Galaxy S II?.
I was overclocking my Galaxy S II earlier and my temprature was up to 46 degrees celsius when i was running a stress test on the phone.
So i just stopped my stress test of the phone then.

How did you measure temperature?I have just battery temp. it is 42.

You can download the same stress test program as i'm using from Android Market. It's called StabilityTest v1.5.
it will test your CPU's on your Galaxy S II if you are overclocking it. But you can check the temprature even if you aren't overclocking.

the temp rise is sort of random, i can play games for hours (and its 26C here) with brightness on auto and so on, it doesnt get hot
then suddenly, it does, sometimes even when im not doing much
didnt get the time to pin point w/e thing creates that behavior
(and when i say hot ofc im talking of very very hot - which is what everyone talks about imo)
killall or restart and its good to go til it happens again

I'm running that app now. I wanted to get an idea of temperatures at stock before undervolting/clocking so I could see how much difference it made. But the phone is seriously hot to the touch, enough to be worrying about. The app's reporting 50C after 37min but it feels hotter than that to me.
Some components are designed to run hot. For example I have an ATI 4850 that happily runs 70+C at idle is rated for up to 120C. But I'm worried even if the exynos can handle these temps what about the other components? The top of the screen feels even hotter back. Could this cause damage to the display for example?
This is my first smart phone but having that much heat in such a tightly packed device seems like a recipe for failure.

You will find temps of 50 deg centigrade and more when using all resources of SGS II (e.g. nav with wikitude drive = camera on) and phone attached to car screen on a sunny hot day.
This is normal!
Touch a nav-device in action and You will find it glowing ......
But contrary to HTC HD 2 SGS II does not freeze or crash at that point.
Leave a device switched off in direct sunlight in a car and it will get hot too, but still it will work .....

my phone was getting extremely hot when benchmarking etc, this was default clock and voltages.
the phone reported it was reaching 50 degrees. thought this was "normal". this was on the firmware the phone was running outta the box.
flashed latest firmware and have since messed about with overclocking, @ 1650 my phone never got as hot as it did stock.
so if you have not done it, flash the latest FW...

So your cpu is not 1200 but 1650mHz now?
Sent from my GT-I9100 using XDA App

Been running tons of different ROMs on tons of different Android devices, and every once in a while there is a particular combo that gets tremendously hot.
Once had my N1 get so hot while using Co-Pilot Live and Spotify while plugged into a car charger, that it turned off and wouldn't come on again for some 5-10 minutes.. Definitely worrying.. Switched ROMs and never saw the problem again.

What I like about being rooted and having CM7

So I haverrooted and flashed CM7 today and there's quite a couple of things I really like
-Boot time is much lower
-SD card takes way less time to prepare after mount or phone restart
-Themes
-Custom Boot animations
-Overclocking
-You have way more customisibilty /lolwut/
-Gingurbread!
-A large communty willing to help
and more
Post what you like a lot about being rooted/cm7 in this topic!

Feeling, that phone is almost completely yours.

Im going to update soon to cyanogenmod I tried it out today but used my back up to go back because i didn't had much time today to install en set up everything i want on my phone. Does gps work with cyanogenmod?

If it doesn't I think you just need to reflash a radio

I went ahead and installed CM7 too
My top thing I love is Control
Even in CM7 there is apps I dont want i.e "mail" & "books"
Now I can get rid of them
I love the fact that I do not have teeter or stocks installed on my phone.
I love that I have changed the font of my phone.
I can finally change lockscreen.
Its faster! (Even angry birds RIO)
It looks more glossy/sharper (It looks like screen had a major upgrade??)
I have not OC'd my phone yet but I may have a play with that later

Text seems unclear compared to HTC default rom. Any help with that?

hey, do you know how to remove the vibration that happens when you unlock the phone(slide to unlock)

And lockscreen can be disabled/changed even on unrooted phone.
There are apk apps for that.

Underclocking improves battery backup. Make sure that the phone is in an underclocked state when not in use and depending on ur usage.
And common factors also matter. Like vibration, ringtones, brightness etc.

I did that too, but then found that my phone got too hot after a couple of hours of normal use. (Web browsing, casual gaming, etc.)

Yeah I was gonna ask about battery life, I rarely have wifi or bluetooth on and set up sync times to be every 4 or 12 hours usually with screen brightness quite low. Do you think I would see significant gains in battery life using CM7?
I'v read conflicting reports on CM7's battery life.

My battery life is considerably shorter than the stock Tom. But o love the fact that my phone is now mine to do whatever I want to. Installed cm7 and its pretty snappy.
Sent from my HTC Wildfire using XDA App

And what about undervolting? Can we uv our devices, so battery life could be longer?

I'll add what I hate about CM7 vs Stock sense
-Battery life is almost 2 times worse. (at 600mhz)
-Contacts facebook integration is poor. (I can live with this)
-In order to use gps I have to flash a new radio. which I didn't because I am a tech noob
-Google maps text quality couldn't be any worse. Almost unreadable.
It's a beautiful rom. Such a shame.

Wildfire overheat problem

Hi folks,
Is it nornal that when I charge my phone, both the charger and the phone get very hot? With spare parts I got temperatures up to 47 °C. I've OC'd my wildfire using the CM7 menu in settings. My values are: 352 min 748 max SMARTASS
Thanks in advance.
P.S. the phone only gets hot wheb charging
Sent from my HTC Wildfire using XDA App

For me thats definitely not normal. Even when im navigating and charging the same time while driving i do not get more than 42° and that i get only at summer-temperatures.
So if you get 47° while loading and doing nothing else i would say its suspicious, when im just loading the phone with cm7 and do nothing else (Cpumin:528) i get not more than 38°.

Install SetCPU and use profiles to set minmax lower when charger is connected.

Deadly Issue ;( !! (UPDATE: occurs with the stock kernel)

Hello everyone...
I have 2 issues with my Transformer
the first one is that whenever i leave my Transformer for couple hours it shuts down !! doesn't occur when charging but it does when it's not.. even when the battery is around 80% !! i had this problem with ALL kernels except the stock kernel which i don't wanna use !! also had this problem for around 2 months...
the second one happened today when i left my Transformer "Charged" at 100%.. and after couple of hours i found it shut down but when i powered it on again i found the battery 27% !!
i went to the battery stats and found that battery was decreasing slowly and there was a gap (which means that it turned off) and after the gap it shows the battery low !! it happened within 6 hours !!
Please help me if you can... !! I'm using Revolver ROM 3.9.5 and "Blades Kernel 3" that comes in the Revolver Parts...
UPDATE : The problem occurs with the stock kernel !!

This sounds very familiar to the problem I had with my Galaxy S2 a month ago.
It kept shutting down every few hours, and it was driving me mad. Then one day I uninstalled the app greenpower, and it was fine afterwards. You don't have the greenpower app by any chance? If not, maybe it can be caused by some other app you normally use?

The battery might be hosed. Have you ever let it hit 0 before? A lot of batteries never fully recover after being fully depleted once or twice.

No i never let it hit 0%... but i don't think that the problem is in the battery
However I'll try it and see what happens !

sounds like a silly question but i have seen it alot. Are you charging through a computer(USB) or wall?

It could be related to setCPU and the according profiles. Just recently I saw that my profiles were messed up after updating ROM and kernel. Might be worth a shot.

Reinstall stock kernel Issue #1 fixed.
Issue 2 sounds like charger shut off and left TF on not charging.

You've pretty much explained to yourself why the thing is shutting down.. It works fine on the stock kernel but not one that is letting you overclock.. Sounds to me like you are either overclocking more than it can handle or undervolting to much or both.
I can almost bet that its not shutting down completely and its just going into a state that the screen is off but the OS is hung up, so its not responding to you turning the screen on.. This would explain why the battery seems to be dieing when its sitting idle.
Not sure about it dieing while its plugged in other than maybe a fluke.

I don't wanna use the stock kernel.. it's really slow !!
and i over clock to 1.4 ghz only since i can't overclock more than that because it restarts itself endlessly if i overclocked more than 1.4 ghz !! i undervolted about -25 or -50.. not much !!
Yes i charge it on a wall or anything but NOT on my computer...
How can i change profiles in setcpu ??

No no you misunderstood! DONT let the battery hit 0.

First, you need to use more exclamation points !!!!
sounds like you are suffering from deep sleep issues. What rom are you running? also, have you tried running a custom kernel and not overclock it? You have several variables that can be influencing your issues, start isolating what may be causing your problems. the kernel seems the must likely of culprits, I would clear the overclock and install setcpu and run it for a but and see if you can replicate your issue.
Sent from my GT-I9000 using XDA App

Just try the non stock kernel, oc it but dont uv it, not all devices can handle uv, even if it is only a little bit. Even take it back too 1000mhz and try to increase the uv and oc by little bits at a time to see exactly what your transformer can handle. I think its the uv thats causing the problems. Experiment a bit and youll find the sweet spot.

I'm using Revolver ROM and i mentioned that...
I've never undervolted till yestersay.. maybe it caused the second problem
I set the clock speed at 1ghz and i'm waiting to see if anything changes..

Yeah... the problem still occurs even after setting the clock speed at 1ghz and default voltage !! using clemsyn kernel ver 22...

Every device is different. Differences in manufacturing etc. You might have a picky device. Plus these are mobile platforms. No fans, just convection cooling. They are not meant to be tweaked and oc'ed they way we do. The stock kernel is very fast. What is it that you cannot do on the stock kernel that the extreme oc let's you do?

I'm guessing my device is bad and it's Asus' problem ! i tried setting the clock speed at normal 1Ghz but the problem still occurs !! the reason i overclock is that because with the stock kernel i get slower web browsing and slower flash playback and slower overall performance!! however I'm back on the stock kernel to check out if the problem is gone or not...
I doubted my device couple months ago... because I've seen everyone overclock their devices at 1.6 GHz Without any issues !! but when i try to overclock a little bit more than 1.4 GHz it restarts itself endlessly !!

Had the same issue a few months ago. Be prepared to wake up to a dead TF.
I sent it back to ASUS and they replaced main board and battery. Under warranty of course. I suggest you unroot and use a stock rom for now.

You stated in an earlier post that the problem does not show up in the stock ASUS setup, but only with a custom ROM and Kernel. How does that make it ASUS' problem. If you buy a car that says it runs on 87 octane fuel and you put 100% nitro methane in the tank and it blows up it is not the manufacturers fault.
