Hi Guys
Basically had two S4's from phones4u, my first was the black mist, which had intermittent faults and in my opinion overheated. This was sent
to Samsung who said that in a nut shell it was fine and the S4's ran warm get over it or words to that affect. As I was unhappy and out of the 28 day return I decided to sell. I was still in love with the S4 so bought another again from phones4u from an ad as an upgrade but I was given the receipt.
This one is the arctic blue version which is really sexy hehe and I love the look, problem is this one seems to also run hot in fact even hotter than the black mist, I was hoping as the blue model was newer Samsung would have identified the heating issues and built the next batches with possibly better thermal compounds or some other way of reducing overheating. This version also occasionally lags and jutters from time to time, I find when on power saving mode they both ran smoother.
My problem is I only have a few days left on the 28 day return so I want to make sure that I havent been that unfortunate to have 2 brand new s4's that are faulty, I know that the s4's run hot and I know that a lot of people are complaining about smoothness, but how hot is the norm and how smooth should they be?? is the question.
I've had loads and loads of phones including, htc one, iphone 5, S3, various windows phones, so I know how smooth smooth should be.
I would like to root and put a custom rom on but I'm holding out to know if this phone is faulty or slightly faulty so to speak, or if everyones S4 is as hot and every so often jerky, I find internet very jerky especially when using chrome browser simple things like scrolling, its not my wifi as my wifes s3 and ipad mini run smooth or smoother.
On Antutu my benchmarks vary from as low as 21000 to as high as 26000?, I know that Samsung is involved in this benchmark rigging thing but surely thats not right?, sometimes I have wifi on dont know if that makes a difference both to benchmarks and heat?.
When I do a stability test, the top half of the screen gets very hot and normally temps start at 30 and rise to around 40 with a gradual increase, as for the stability it goes from 140 to sometimes 70 (3 or 4 times) it also takes around 15% out of my battery for around a 10 min test.
I have attached screens as luck happens the last stability test the phone went to under 40 as you can see, I charged the battery left it a while then ran the test fresh, please can you run the stability test on your s4's guys and put my mind at rest or help me prove to phones4u my phones running hot.
My firmware is UBMGA - i9505
Many thanks

Of course s4 is hot when you use processor a lot or when you recharge s4. Mine hasnt ever become uncomfortable hot but it is warm. Antutu score doesnt mean anything because everybody has different apps running and so on. You had two s4 and it is almost impossible that both of the phones has problems. Remember that s4 is very powerfull and it is very tight package so it is normal if its hot.

My SGS4 is always hot during playing games. Sometimes extremly hot. I've sent it back for warranty repair but they said it's ok. So no luck.
S4 is hot
its hotter than S3 i used to have. It says 1.9Ghz but in games or benches its sometimes lower even than 1.5Ghz because of thermal throttling... when i used 1.5Ghz as max in setcpu i had better results in 3dmark! yep! and antutu score become stable - a bit lower but stable, with 1.9Ghz i had 24000-25600. with 1.5Ghz i had 24300 almost every time.
But now im using UV kernel and i UV -0,50V and i set thermal throttling temp to 90'C, now my antutu score became almost stable at ~26100
I think samsung overclocked this S600 to much... 1.5Ghz is almost stable but 1.9Ghz is definitly not.
So basically, I'm on PA 4.0 LS980 and I noticed that Riptide GP2 was lagging pretty badly last night. I checked the temps and it was near 67c. I know that's perfectly safe for the device, but I think it exceeded the limit, as it was throttling down to 300MHz or so. Also my Antutu was 28K, then 20K right after, so there is clearly massive throttling. I've seen talk of a fix in the custom kernel thread, but I was wondering if this had ever been figured out? Thanks!
Hi all, my S4 i9505 has been getting battery temp of 36degree Celsius and GPU temps hovering around 44-52 when doing nothing with some background apps (reaches 64 when playing Clash of Clans), 42-48 when in standby. Is this normal? The phone is rooted and has ktoonsez' kernal. I don't think I noticed these high temps before I tried to overclock the S4 to the max (was just playing around to see if GTA VC will receive any performance increase) which resulted in the phone rebooting twice while vibrating a little. Since then, I reverted the overclock by going into recovery mode and then reboot and only now I noticed this temps., also, I had to uninstall GTA VC as all it did after the reboots was freezing at a white screen after the intro. Thurs far, I have not noticed any performance issues. I am currently using Danvdh's customized Google Edition 4.4.4 ROM.
And if it matters, my phone scored an average of 22k in AnTuTu at 54degrees. 26k, albeit below the average S4 when I left it in standby for the whole night.
I'm using a Galaxy Note 4 N910H (4.4.4). During normal usage (web browsing, texting,etc) the temperature is 45-52 °C. The main problem is, when I play games for 15-20 minutes the temperature reaches 60-75 °C and the GPU throttles to 160-266mhz (CPU-Z). It makes my games laggy and unplayable. How do I fix this? Will upgrading to Lollipop solves this problem?
I have the same issue. What i did was i underclocked it with an app called 'Performance control' and it has significantly reduced getting too hot. You should try it
What causes the CPU of S4 heats up so fast even in simplest usage, because its strange among the other phone
How did you determine that it's the cpu that is heating up?
It heats up on its own or only under certain circumstances?
