And yes, it does lowers the overheating a lot for me.

ok so it's not a hardware problem that produces overheating. I hope so because i'm going to buy a galaxy s4.

I'm not sure between i9500 and i9505 but for me the heating issue is important, so I will choose the one that has no heating problems.

[Galaxy S 4 Q&A, Help & Troubleshooting] kris7679:
finally overheating solved :)

If you wanna your s4 getting just bit warm while havy gaming in games like real racing, modern combat you need to do 2 simple steps very important you need to do this both things. So first switch off all bloatware and most important turn off screen rotate in notifications bar so you have to have switched on only wifi and sound all rest turn off. Next go to settings/accounts/google and there in localisation settings turn off let google applications access to localisation settings option. Now you are ready to go just try to play some have game for longer time and be happy your phone is just bit warm ! :) Test it please you will be happy from results. Overheating SOLVED !

only dont do tests while on charger cause while charging you will not see big difference stilll better even with charger connected :)
[Galaxy S 4 Q&A, Help & Troubleshooting] kris7679:
i thought last thing what i did sorted overheating but it was small mistake

please switch off your google now completely and switch off localisation services for google applications and delete apps proceses from some cleaning app like clean master before gameing in some have game than you will see how your heat will be dramatically reduced :) i think this is only way to overcome overheating. Google now is responsible for overheating...propably people without this switched on are happy from their devices thats why some people said dont have any overheat because they just simply dont have google now switched on heh :) Try this you will be happy, I feel like have other device now. Playing modern combat 4 2 hours and only bit warm ! :) that was impossible before. Before I had hot after 10 minutes in modern combat heh. Dont forget to tell thank you :)

---------- Post added at 05:44 PM ---------- Previous post was at 05:24 PM ----------

just tried with gangstar rio while phone was on charger all the time used to play 1 h while on charger and phone still not overheat !!!! no difference now witch charger or not phone is still nearly cold !!!. So mates you have now solution ! and this really again really work ! he I cant believe I fixed it and so many people couldnt before heheh. Propably you dont even need all this things what I wrote above, enough will be if you will swich off localisation for google services and after you will switch off google now service completely. But if you want you can do all like I did so as well kill all processes before gaming from some memory cleaner but I think this is not important and completely enough will be to sort google like I said.
[Galaxy S 4 Q&A, Help & Troubleshooting] armaan.ag:
I have talked to a Samsung representative at a higher post and i was told that s4 does have this problem in their early batches. Take your handset to the samsung service center. If your phone is heating excessively even in normal usage then your handset piece is faulty, it HAS to be replaced.

I had exactly the same problem, and after getting its hardware(the change the motherboard only) replaced for 3 times the problem wasn't solved , so they finally replaced the entire piece after alot of requests. Even you have to try for a full replacement..

I paid 40000 for this phone, so i do not expect to compromise on any features which other users of the same model are enjoying. Sorry, but i am not content with turning off any of my services to simply 'reduce' the heat.

[Galaxy S 4 Q&A, Help & Troubleshooting] FreezIn:
Believe it is a battery issue

So I flashed CM 11.0 on my S4 (i9500) and it is on android 4.4.2. I am still having overheating issue. I took out the battery and read the label behind the battery. It said Rate: 3.8 1300 MA. Then the battery said 2600 mah. Is 1300 ma equal to 2600 mah? If it isn't it might mean the battery has a too high voltage or something. Also does the overheating eventually break my screen and camera?
[Galaxy S 4 Q&A, Help & Troubleshooting] Nealieboyee:
I would think the components are rated to handle the heat. Have you used a thermometer to check the temps? I had overheating with my i9500 and the only thing that helped was flashing a different modem.
[Galaxy S 4 Q&A, Help & Troubleshooting] FreezIn:
Actually it is not a battery or software problem. I have open the phones internals and guess what is there? It is those proccesor that is making heat i think.
[Galaxy S 4 Q&A, Help & Troubleshooting] CapetoGT:
Visit an expert??

Guys, I don't know about you, but a month ago I paid $600 for my s4 mini in my country, This overheating and battery draining is not my problem to solve, that's the last conclusion I reached, so I went to a Samsung service center, and the representative told me: "This phone has that problem, not all of them but a low percentage has battery issues" So they gave me a new battery, with the premise of changing the device if this doesn't solve the problem. I'll let you know how it goes.

So my advice: you just paid for a nice phone (If you bought it at launching your phone can´t be more than 7-8 months old) so keep it simple and go to an expert. Or at least make that before you install a bunch of custom roms and kernels and you lose your warranty.

I did try many of your well-intentioned advice with no luck... thanks though.
[Galaxy S 4 Q&A, Help & Troubleshooting] FreezIn:
I hope the new battery solves your problem. Im using my s4 as a handheld gaming device because the s4 overheats. My overheating is like kinda solved I have a t mobile sim card that has no service and turned on airplane mode. Also once I removed android tuner, it also helps the overheating. When I play GTA 3 about an hour, the phone feels like 65 C also I have lost my warranty because I have cm 11 on it and rooted so I can get it replace or get technical support....
[Galaxy S 4 Q&A, Help & Troubleshooting] CapetoGT:
New Battery

On new battery...Well...No overheating so far, battery draining has stopped while standby,

6.2% of battery draining per hour, normal activity, wifi on, light gps, light data, 8-9 calls (4-5 min.), 4-5 pictures...I believe that's a normal rate right?? Battery life 12 hours with 25% still remaining...

Let's say my problem it's temporarily solved, but remember my overheating started a week after I start using the device,

I'll wait and see and keep you posted...

Next test: Full charge over night with device off, then turn it on and measure standby battery time (no wifi, no data, no calls, no gps, no apps) let's check real standby power.... see ya

[Galaxy S 4 Q&A, Help & Troubleshooting] FreezIn:
The only thing that helped me the most was to flash a new rom. That removes all the bloatware which helps the overheating problem. Tried flashing a new modem but didn't do anything. Played GTA 3 for about 1 1/2 hours and the temp was around 60-65. I will say that with custom ROM it is better without would probably be 65-70
[Galaxy S 4 Q&A, Help & Troubleshooting] iede:
The only problem with I9500 is A15 core which is not good in term of efficiency. If you are not concerned about performance try to switch off your A15 and use only A7 instead with 1200 Mhz or even 1400 Mhz. I already test it and with only A7 core active the performance is slightly better than S3 I9300 but no overheat in any condition.

Yes, you will sacrifice your performance but if you hate overheating it's worth to try :)
[Galaxy S 4 Q&A, Help & Troubleshooting] armaan.ag:
Well, I do not understand one thing, the heating issue i and maybe many other are facing is unusual. Not every owner of an s4 is facing it, which means this is a hardware fault not software. The only thing the service center does is change the motherboard which does not affect the heating problem at all. If there is ANY new idea to overcome this pestering heating issue, please enlighten us.:angel:

Im having the same problem for my s4 i9500 :( i updated the firmware and still in KITKAT 4.4.2 i have the Over Heating problem , Do any 1 have a proper solution for this ? cuz my phone is is service centre and they cannot rectify the problem , they jus formating the phone reinstalling the firmware .

i re - claimed Warranty and they now saying they will change the board , but after reading the posts i feel like after me getting the phone with new board i may still have the same problem , please a SOLUTION :crying:: Thanks in Advance .
[Galaxy S 4 Q&A, Help & Troubleshooting] FreezIn:
I updated to 4.4.2 too ( switched from vanir ROM ) and its still overheating. I couldn't re claim my warranty so they wont fix it for me. I don't think changing the board would do anything. It the proccesor that is generating the heat. Unless you under clock it or something that would probably fix (a guess only).

If your S4 has root access , you can try limiting your tethering speed ,

this will resolve the overheat problem ,

Thinking of buying S4 Mini Black Edition -- Is the heating issue Solved OR its still present on every phone ?
[Galaxy S 4 Q&A, Help & Troubleshooting] flusi100:
I have dealed with this overheating issue for some days now. If you google for "s4 battery drain" you will find several reports, some of them a few months old. It is a serious problem, most probably o bug since 4.4.2 or so, only affecting the s4. Randomly the current raises up to 800mA and drains the battery within 5 to 6 hours to death, even when screen is off. The phone of course gets very warm. It cannot be solved by dimming the screen, limiting bandwidth or disabling Wifi, GPS or bluetooth. The built in battery monitor doesn't help you, nor do the logs or other apps.

Many people were complaining about bad battery performance and samsung already offered battery replacement for free. But I'm sure this is not the massive battery draining problem. As I mentioned: the phone gets warm and burns too much power even when sleeping. This is not a battery problem. Although I also read that wrong battery calibration could be the problem Imho this is not the cause.

I have tried nearly all suggestions: Reboots, pulling out battery, disabling sync, installing and tunig CPU-Tuner, Battery Monitor Widget, greenify... no success.

I often read that one of the actions above helped, but reading on lead to the disappointing result: it worked just temporary. For me it was the same with one or another measure and/or reboot. But the problem seemed to randomly disappear - an reappear. It was hell for me because I bought a new i9505, rooted it voiding warranty and just thereafter faced the fact, that I could use my phone just for warming my tea for half of the day.

BUT I found a solution, that works for me since almost 12 hours and hopefully will last. Just eject the SD card and do a reboot. Initially I used a 32 GB card. After removing the problem was gone. In the meanwhile I use a 2GB card, erased it using the phone. The smaller card seems to work. I read that a media library permanently is beeing updated. Not sure about that. Maybe it is the size of the card. Maybe not.

I can't tell what the problem exactly is about. Just give it a try! Good luck!

So in short, remove any extra cover ,or even if its just a bumper, to reduce heating problem. (Its my experience)

The issue is with Lollipop 5.0.1 update.

well for starters, my single core soc is already overheating on my htc desire hd, i don't believe 28nm or 32nm process from a 4-core or 8-core would reduce the thermal output.

these manufacturers are obsessed with the horsepower (when it's already more than sufficient..), instead of battery life and the heat output.

i don't think it's a related software issue, unless you are allowed to disable few cores, then that would solve it.
