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
[Galaxy S 4 Q&A, Help & Troubleshooting] Meltus:
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.
[Galaxy S 4 Q&A, Help & Troubleshooting] exxi:
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?
[Galaxy S 4 Q&A, Help & Troubleshooting] Meltus:
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!
[Galaxy S 4 Q&A, Help & Troubleshooting] exxi:
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
[Galaxy S 4 Q&A, Help & Troubleshooting] Meltus:
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 :p
[Galaxy S 4 Q&A, Help & Troubleshooting] exxi:
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 ?
[Galaxy S 4 Q&A, Help & Troubleshooting] Meltus:
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.
[Galaxy S 4 Q&A, Help & Troubleshooting] Joe0Bloggs:
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... :D
[Galaxy S 4 Q&A, Help & Troubleshooting] ctl8:
What about brightness settings and whatnot. Should all be the same, so you have to give a standard.
[Galaxy S 4 Q&A, Help & Troubleshooting] aami.aami:
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
[Galaxy S 4 Q&A, Help & Troubleshooting] bala_gamer:
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
[Galaxy S 4 Q&A, Help & Troubleshooting] Joe0Bloggs:
You can read the CPU temp instead of the battery temp? :o
[Galaxy S 4 Q&A, Help & Troubleshooting] aami.aami:
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 :D

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... :D
[Galaxy S 4 Q&A, Help & Troubleshooting] bala_gamer:
Yes we can read cpu temp and battery temp separately, use system tuner app to read cpu temperature.
[Galaxy S 4 Q&A, Help & Troubleshooting] bala_gamer:
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?
[Galaxy S 4 Q&A, Help & Troubleshooting] Meltus:
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?
[Galaxy S 4 Q&A, Help & Troubleshooting] bala_gamer:
Are you talking about battery temperature or cpu temperature? Haven't heard any stories so far regarding damaged battery, but may be possible.

[Galaxy S 4 Q&A, Help & Troubleshooting] Meltus:
Battery temperature. If someone's experiencing temperatures in excess of 50C and bad battery drain it would indicate a problem.
[Galaxy S 4 Q&A, Help & Troubleshooting] bala_gamer:
I thought he was talking about cpu temps, yes anything above 50 for battery is not at all good.
[Galaxy S 4 Q&A, Help & Troubleshooting] aami.aami:
what u said is correct. but dude this is 2013, many people around the world including my self want the best in class performance in every aspect what so ever. to be honest i used to play a lot on my laptop which i owned last year but then i sold it after i got Note 2 cause it had that huge screen and some nice development has been going on in the android world for games.

so i started playing a lot on my smartphones which are actually destined to replace laptops and they are doing that! no body can deny that! my Note 2 didnt use to get as hot as S4 which is powered by next gen processor. so its my right as a customer to demand better and cooler performing mobile. and when i m free i use my smartphone for gaming and downloading movies at the same time. so running wifi and gaming at same time gets the device real real hot. im in pakistan and its hot here u know cause u r indian i guess... after about 30 min or so of wifi and gaming, it becomes so hot i LITERALLY NEED TO PUT IT DOWN TO COOL OFF!

thats why i said what ever i said.

im not arguing for the sake of argument but just saying what should have been done!
[Galaxy S 4 Q&A, Help & Troubleshooting] Rashgud:
Misleading

i think you are misleading...the temp in the adb command is the BATTERY TEMP and what the OP wanted is the EXTERNAL THERMISTOR which is on the lower part of the *#0228# command.

the battery temps are always fine, the problem is with the external temp which is making the handset hot to the touch.
[Galaxy S III General] jprentzas:
*******This way of uninstalling bloatware has been tested only on Samsung Galaxy S3 Stock Rooted firmware. I am not responsible for any damaged devices!!!!!!!!!!!!!!!!!*********

**Read all the threat please**

1. Root your phone (in case you haven't http://xdaforums.com/showthread.php?t=1957273 )

2. Download the Moborobo software and install it http://www.moborobo.com/

3. Disable kies

4. Connect your phone with your pc and start Moborobo

5. Enable USB debugging in the Developers options of your phone (Settings->Developer Options->USB debugging)

6. Follow the instraction in the program to connect your phone with Moborobo.

7. Once you have done with that go to apps on Moborobo and then go to System Apps

8. There you will se all the apps that are installed on the phone except the apps that you have installed.

9. Check the apps that ypu want to uninstall (Please follow this guide for the apps safe to remove https://docs.google.com/spreadsheet/ccc?key=0AqTvctlW89DtdC1qVUlLeVFTV3ZOdUtDclpBdVRQOUE&pli=1#gid=0 )

10. At the begining if your phone asks to give administration access to moborobo click yes and make sure that is always yes.

11. Once the uninstaling of the apps has finished reboot you phone.

12. Now all the apps that you do not want to your phone has gone.

**If you want to uninstall the apps that you have installed follow step 7 but go to User Apps.

***If you want all these apps back and return to complete stock***

Follow the link in step 1 to reset the flash counter.

Make a back up of your contacts , photos, etc just in case.

Download the correct firmware of your device and flash it via ODIN.

This will unroot your phone, custom recovery will be replaced with the stock one and all your mods will return to stock.

After that wait for phone to restart.

If you get into Bootloop just press Vol UP + home + power at the same time until Samsung Galaxy SIII logo appears.

Make a full wipe data/ Factory reset and restart your phone.

Hit Thanks if did a good work

I just want to root my phone because i soft bricked it. I want ot be back on CM nightlies, and most of all i want to sim unlock.

Yes I know I am a noob but I have put in a solid 6 hours of searching, which is ****ing stupid because one forum member here is going to be able to link me the eact rom and kernal i need in 3 seconds.

I just can't understand why people ask for the exact file to flash, instead of trying to find out for themselves.

From what I see, its not that hard to find what ur looking for, unless ur too lazy to go through all the search results! And you can always double check with other members on whether ur doing stuff right or not.

If someone suggests you flash something, and you do it without knowing why or how, ur back to where u were before asking.

Believe me, the fun is all about learning what ur doing and why ur doing it. So after u have solved ur issue, u have not just helped ur device, u have helped urself too.. :)

Word of advice....don't go offsite for rooting methods....other sites get their info here, and if not, it probably shouldn't be trusted anyway.

And for rooting....visit the PhilZ thread....search the thread for the kernel that matches your firmware and download the ZIP version. This can be flashed in the stock recovery....without Odin. ....

Not sure how? Search function will help......

My GSM GNex had been acting a bit weird during the past few hours, getting hot and then rebooting two or three times, it has been getting hot before on the kernel I use but never rebooted. About an hour ago now it just froze with the screen on and after a while it shut itself off rapidly. I took the battery out and put it in again, but nothing happens when I press the power-button, if I plug in the charger it doesn't show the charging symbol.

It's dead basically, no matter what I do with it and I didn't even do anything in particular to kill it. It had been running fine on Paranoid Android from May 5th with AK Rubik for about a week and a half.

Anyone know a fix for this when I can't even reach recovery or fastboot? Why did this even happen in the first place?

For now I'll just keep the charger in and hope it goes back to life somehow.

The phone gets hot around the camera when plugged in to the charger, so... it can't be completely dead... right? :crying:
