Phone over-heat!! Help please!

I was charging my phone last night, and in the morning my phone was extremely hot. I've never felt anything as hot before with my phone. I had to shutdown the phone and pull out the battery fast. Seriously, I thought my phone would explode. Did anyone else experience the same problem??

yes I am. I've also noticed that my phone charges really fast too, maybe 2 or 3 times faster than its normal rate?
Any ideas to prevent it from overheating while charging??

wrong place to post, u should have posted it here or here

Do you have an app called "SETCPU"? if not some android builds or older builds don't have control over the CPU and leaves it running at 998MHz even in sleep mode when it should be 245MHz in sleep mode. Get the app in this fourms. It will even allow you to overclock up to 1190MHz for extra proformance but may kill your battery faster. I once had this problem and sloved it with SETCPU. Good Luck.

you can also set a profile for your CPU to max out at say 600mhz if it goes above 40 degrees c or what have you.

Or maybe his charger is faulty...

[Q] Overheating Motorola Defy

Hi!
So I've installed BatteryLife to monitor the percentage of battery remaining as well as the temperature of my Defy, and I've noticed that as I run some apps, it sometimes reach as much as 40°C. What I'm worried about is that it might fry my processor, if I assume things correctly. Will it be that way? How do I solve this?

not use it?
40C is fine.

the temperature that you talk about is that of the battery. 40C is fine if you play some games or similar cpu intensive apps.

Yes 40C is fine!

Yesterday I have 48 C, and the phone was acting normally, so 40 isn't a issue. Also, the phone has cool down mode that activates when it reach critical temp.

mine is normally 37degrees. but make sure your rom doesn't have some overclocking settings and vsel is not set too high.

Once my phone did reached 50°C and I open up the battery cover for better ventilation. I did this because I was on 3g continuesly online while listening music. Phone run no problem for another 2 hours non stop..

yeahh true that..
i recently bought a Defy plus...and it overheat when i use 3G or any background download...it gets so heated up that i have to put it before AC to cool it down..now it seems like i dont owe a DEFY+...DEFY+ owe me...as i have to take care of this ****...everyday..!!

[Q] Nexus 4 hits 122 degrees!??

Hello,
is it normal that my Nexus 4 hits 50° Celsius (thats 122° Fahrenheit)?
I was just playing that 10 fast fingers app and it seemed like a light app so I was pretty surprised how hot it got and downloaded a temperature widget...
Any opinions? Did your device get so hot? Should I ask for a replacement?

Sounds fine to me? The glass doesn't block heat transference, so people really notice it a lot on this device. When you get above 65°C is when I'd start to worry.

would have surely gotten some blisters if I kept my hands on it guess its normal but a bit of a crazy standard as the phone was only running a very simple app (nothing 3d or anything only checking typing speed)
maybe anyone else has something to say about this? i'd like a second opinion if possible

Was the temp on the CPU or the battery?

don't know what the temp on the battery was but the source of the heat was definitely the cpu

The CPU creates the heat and much of it is transferred to the battery. One theory is that these phones throttle so quickly to prolong the life of the battery. I think they shut off at 70°

Are you on stock kernel? Try franco, he addressed this issue in his code. If you search his thread you will find useful info.

50 is fine. Desktop and laptops can often run up to 90 degrees Celsius. Also, you can't get blister from something that's 50 degrees.

I have try both Franco and matrix kernels and they don't stop hot. Phone battery still 40+- degrees by Celsius. Up parts of phone hot and is not nice feeling keep it at hand. May be is some ideas how make phone more colder. Hu use cm or other roms? How it hot?

[EXPERIMENT] S4 Overheating and how it affects battery drainage [PLEASE PARTICIPATE]

Dear Community,
In this thread I want to gather a sample to investigate to what extent the S4 suffers form overheating and how this affects the battery drainage/life. I urge you to participate as I am collecting a sample to submit a formal complaint to Samsung to raise awareness to an issue that is widespread among S4 users and to push Samsung to address this issue accordingly. In order to provide your sample please follow the instructions below and report back in this thread with the relevant information. Please first indicate which variant you have: Quad/Octa (i9505 or i9500)
Please download BatteryGraph (it's a great app to measure Battery drainage accurately) https://play.google.com/store/apps/details?id=com.modroid.battery
Run it once after download to initiate logging. Let it run for 10 minutes to allow the graph to built up a bit.
Then please Download Antutu benchmark run the benchmark fully exactly 5 times back to back (continuously). After that please enter the stock dialer (as quickly as possible) and enter *#0228# and post the temperature (external thermistor) after the tests in order to determine the maximum temp that the device reaches under continuous stress.
After that, please enter the app Battery Graph and zoom into the graph to the maximum level. Scroll slowly along the curve at the time when you performed the Benchmarks and tell me if there are interruptions or 'skips' where the battery drops 1 or 2 percent at a time and where the App does not Register a graph for those drops. Sequence/scroll slowly along the graph 1% at a time and make sure that the battery dropped 1% at a time. Please report of the battery has dropped more than 1% at a time. Please make a screenshot of your battery graph in the App and post it here for collection. I will analyze the graphs subsequently and compile it in SPSS to submit our findings.
If there is a drop of 2 or 3% at a time it means that you are experiencing Battery Percentage skips/cliffs which could indicate either a defective battery or defective device which might be the cause for the extensive heat development.
Thank you for your participation. Hopefully Samsung will listen to us and address the issue to give us the perfect S4 that we deserve.
Best,
Thomas from Germany

That battery app polls for battery level changes every 5 minutes by default. I think almost every device will experience a drop of more than 1% every 5 minutes under constant stress testing. You can change it to poll every 1 minute in the settings, which you might want to mention, but even so isn't it entirely possible to lose more than 1% a minute with everything turned on (GPS, Gestures, etc.) and ~17 minutes of constant cpu/gpu stress testing? It's a nice idea but it doesn't sound like it would yield very accurate results, unless I've misunderstood your post.
EDIT: Nevermind, I see how you can step through it 1% at a time now.

I've also noticed that you cannot really zoom in very far and at the highest zoom setting the % is still displayed in multiples of 10. Kind of tricky to differentiate between a 1% and a 2% drop.

You might be right, what would you suggest in order to yield more accurate results? I suspect that the heat is directly linked to a very quick drainage of the battery. How can we measure how much it affects the actual battery drainage?

I'm not criticizing you or anything and I'm not saying it's a bad idea, It's just that obtaining accurate battery results are tricky as everyone's device is different, has different settings enabled and are running different kernels/ROMs/etc. Batteries also seem to get more efficient as time goes on so newer devices might suffer from higher battery drains.
I'll run the battery temp test now though and see how hot mine gets!

I like your critical thinking, obviously you are right it is very trick but I believe the heat test itself could be very indicative. In the meantime I will try to find a better way to measure battery drainage.
So everyone please try to run the benchmark multiple times and submit the temperature.
The most I was able to get was 52C
Thanks

Pre-test: 29.9°C
After 3 tests: 35.0°C
After 5 tests: 37.7°C
After 7 tests: 38.4°C
After 10 tests: 38.8°C
The temperature increased less and less so I don't know how much higher I could get it.
Also, an easier way to poll the temperature is to do "adb shell dumpsys battery" over ADB. The temp will be displayed as something like 388 which means 38.8°C
Edit: It might be worth noting that the top of the phone, around the camera but more so on the screen side (so the cpu?) got incredibly hot. Almost too hot to touch. Kinda worrying, but I have spent the last half an hour stress testing, I guess

Thanks for your contribution Meltus! Really appreciated my friend. Also thanks for the ADB command it does make it easier but I doubt that you've read the correct temp as 38 appears to be quite low compared to what i got. Is your S4 a i9505 ?

It's also the temperature that dialling *#0228# gave me (I double checked they were both the same each time). And no, I have an i9500, running Omega ROM, if that helps.

Might want to mention the elementary precaution of taking off all case covers except for the stock case before testing to prevent insulation effect of case covers increasing battery temperature...
While you're at it you might want to standardize room temperature to 25 degrees C... I know for a fact that my device would never get hot no matter what it does if running in the freezing cold air-con'd metro...

What about brightness settings and whatnot. Should all be the same, so you have to give a standard.

Pre-test: 36.2°C
After 3 tests: 51.4°C
After 5 tests: 54.6°C
After 7 tests: 56.9°C
dafaq right??? im really annoyed at sammy for this overheating S4... after 7 times testing the Antutu, i stopped and LITERALLY put my S4 in the lower compartment of the refrigerator to get it cooled down quickly cause im pretty sure the heat sensors inside would definitely be having some testing errors and the temperatures would be really really higher than that. even when i swipe between different homescreens the phone gets to 47°C which is really annoying.
can someone pls for the LOVE OF GOD provide any solution to this freaking problem? i have been worrying a lot for spending my $730 on an overheating phone...
i have S4 i9500 Exynos version

oh and i have half the brightness all the time for everything and auto brightness turned off

Are you talking about the battery temperature? If so something is extremely wrong with your unit, my battery temperature never went past 45 even with high stress.
If in case you are pointing out the cpu temperature then there is no reason to freak out because the cpu can handle upto 90c + and can cool off pretty fast
Edit:
And why on earth you ran Antutu for 7 times continously lol? None of the current generation phones can handle it for 7 times on a row afaik

im talking about the cpu temps. i ran antutu cause it was asked to be done for this thread.
and why would it be silly to run any app 7 times on the flagship device? its made to run the apps as much as people want thats why we pay a huge amount of money for these devices dont we? or else we should buy the low end devices
just saying cause i had heating up issues with devices before infact my last device Note 2 used to get a lot hot but not as much as this S4...
i desperately need a solution for this...

You are not buying a flagship device just to run Antutu n number of times, do you? yes I accept we do pay huge money but that doesn't mean we can push the limit of a mobile and complain about it from a general user perspective . , it can be only done for experimental purposes and to understand the power /thermal envelope provided that it's done in the right way.
But how does running Antutu 7 times matches a real life scenario? Highly unlikely isn't it?
We are already pushing the limits of raw cpu power for a mobile, raw a15 cores are power hungry and often tend to heat faster than previous generation. Hence arm introduced the big little. The mobile heats up during heavy stress, but but that's expected with these powerful cores right? I'd better utilize the power wisely when needed rather than using it all the time. The cpu indeed gets hotter when stressed, it's the same With my s3 too the cpu temps reached upto 80,there is built in throttling mechanisms which will take of the cpu once the cut off temperature is reached. Have seen many benchmarkers these days using freezer test due to the thermal throttling in new gen devices. Yes the s4 heats up pretty quick than other mobiles but also cools down pretty fast and I think that's the way it is destined to work.
Hei one more thing, did you note how long it took to fallback to normal temps?

We were doing it to see if there was a correlation between excessive battery drain and overheating batteries. Mine never got any hotter than 40 and I have pretty great battery life. The OP was seeing temps of 50+ and I'm guessing he has poor battery life.
Could there have been a few batches of bad batteries sent out with devices?

Battery temperature. If someone's experiencing temperatures in excess of 50C and bad battery drain it would indicate a problem.

Experience with heating of the S4

Hello XDA,
I decided to open this topic as I've been fumbling around with my device alot lately. Lately I've started to notice a dramatic increase of temperature while using my device running simple tasks like chrome, whatsapp etc. This only sometimes gets the device till 45-50 degrees Celsius, this is the CPU's temperature. While gaming, it reaches a whopping 60C ! Flashed to stock, updated to new base, reboot after reboot did not solve this issue. While charging sometimes it gets really really hot!
Now I'm wondering about your experiences, how hot does your CPU get doing what tasks? I'm wondering because im contemplating whether or not bring my device in to a service center as I've never had a device CPU above 45 degrees celsius.

I think its normal.
Does your phone start to lag when it gets hot? If not, then in my opinion you are still safe.

Same here, but I only realized it was heating last month. Maybe it has something to do with a background process? Sometimes I can even feel the heat when my phone is in my pocket

It doesnt lag, but it does heat up ALOT while doing light tasks, up to 50C
