Does Overheating Affect Brightness???

Hi All, I have S4 I9500. I keep the brightness at full all the time (Autobrightness is disabled). I have noticed that when the phone is overheating (like when playing hardcore games or browsing with 3G), the screen dims a little for a minute or less and then returns to full again. It keeps doing this as long the phone is highly hot. I read an article talking about this issue but in the Xperia Z, it says that this is normal as the phone warns you about the overheating and to preserve the screen and the battery. Is this true for the S4? I'm really waiting for your reply. Thanks.[/SIZE][/SIZE]

phone heating

Phone heating problem is solved but the firmware update caps performance drastically please check the below links . Basically after the update the A15 cores ( performance cores) are not used at all only the A7 cores are used I.e the phone changes from S4 to S3 or any A7 quad core phone available in the market .

Did the June OTA fix it?

Hi Palash, any improvement you saw on overheating issue after the June 11 FW OTA update? For me it starts warming the moment I start using 3g otherwise it's just fine on wifi.

---------- Post added at 01:38 AM ---------- Previous post was at 01:19 AM ----------

Did anyone notice improvement in heating issue of S4 after June 11 OTA update? I am wondering if this update includes fixes for heating issue or was it only for the bugs like camera..! Mine still starts warming the very moment it uses data on 3g, however on wifi its perfectly fine. It seems 3g is a battery hogger. I am yet to try this on some other S4 to realize that its not only with me - and so confirm whether mine is faulty and put a request for replacement.

After the latest Indian update few days back, (I'm based in Thailand) I just encountered intense heating in last two days.

Nothing new has been installed.

Yesterday , when I first experienced it, I checked the processes. Nothing unusual.... so I just turned off data connection and it became normal in some time.

Today , while travelling , I experienced the same intense heating. and the phone was in airplane mode.

I was earlier thinking that the issue is with data connection or radio. but when the same thing happened in airplane mode, I just got more confused.

TempMonitor it's working fine to my I9500, or can try System Tuner, I prefer the first one because you can see the temp CPU in the notification bar. I compared those apps at the same time with the same CPU temps.

Do you think replacement will help?

May be the 3g receptor is faulty. Have you checked your device with other s4 - to know if it is with all s4s .. if not I am thinking to request for replacement.

---------- Post added at 05:07 PM ---------- Previous post was at 04:54 PM ----------

For me the moment i start using 3g it gets to 48C .. it went to even 55C just while browsing FB on 3g. However on wifi it stays cool. I am now going for a replacement so if there is a fault in 3g receptor. While playing games its b/w 45-50 not beyond that - games like Ashphalt, ironman etc. How is your device now after update.

---------- Post added at 05:18 PM ---------- Previous post was at 05:07 PM ----------

Mine also heats upto 48C while using chrome on 3g however the same on wifi will still be little less hot. I keep thinking is it only with my phone which is faulty.. so perhaps I should ask for replacement. Are these faulty devices or is it with all octa core S4s. I recently noted 55C while I was just browsing FB on 3g.

Mines the same i9500 UAE

My i9500 is overheating in Dubai, I have the MEA firmware installed, which is the latest in this region.

With the temperature outside around 40+ degrees and the phone running unpleasantly hot - its not ideal :( This plus the octa core switching issues is making me very unhappy. Otherwise a pukka phone and I am very happy with it.

The phone does run allot kooler with power save On and 3g off. 3g Being the main culprit here. A factory reset did make a big improvement to the temp as well.

I am running the phone without SD card to see if this makes any difference.

Samsung please sort these issues out with a firmware update, or at least let the octa- crew swap their S4s for a Snap dragon i9505. I know you are listening! Whether you do something about it is another story. Tempted to drop it in for repair but nor sure what Samsung's techies will do?

Hi, when my s4 was stock and new, my geekbench2 was about 3200-3300, quadrant 12100-12800, antutu 24000-25000

I have been playing around, used pre rooted stock firmware and tested the benchmarks still the same. After I tried KT kernel, then foxhound with faux kernel with overclocking and undervolting. Qudrant manage high 13000 and geekbench2 3100. But once I used antutu, the phone shuts down and turns black. Had to connect charger to wake device up.

I reverted stock firmware without root and antutu at range from 13000 to 16000. however qudrant still 12000 and geekbench2 3300. device is very hot. using the device feels the same, not sluggish. Cannot figure out whats wrong. Did i fry my cpu?

Ok but what is wrong with your device? You don't like "50" number or what? My sgs4 s600 also reaches 45-50 C and there is nothing wrong with it. During antutu benchmark temp goes much higher and my device remain stable. This is passively cooled gigahertz cpu so it produces massive amount of heat. Don't expect it to remain at ambient temperate.

Hi, yeah I just bought a GS4 I9505, and I've got several problems with it ; overheating, battery drain, even some lags. I just updated it with the last OTA release, nothing improved the use of my GS4 I9505...So I called the Samsung service of my country, and they told me they've never heard of that kind of problems before. I'll try a little bit later to do a factory reset and wipe my SD card and deactivate the Samsung services on my phone. Hope it'll be better, otherwise I'll bring him to the store I bought it.

Hi i've just got my new S4 I9500 octacore from my carrier here in my country argentina, it came loaded with default stock firmware, but I need to know if these temps are normal.

I'm posting a youtube video so you can see what's going on... Are these temps normal, first of all

- Demand mode with throttling up to 1600 ghz ,CPU temp rises to around 75-80 C while playing modern combat 4

- Demand mode limiting max cpu to 1000 ghz CPU temp goes around 60C

So I've seen some videos of guys doing a performance test, while gaming and they checked with system tuner CPU temp and had after 5 minutes of gaming with Modern combat around 52C and with throttling mode I believe with max CPU speed to 1.6hhz so is my phone defective?

We all know there's no thermal compound or discipation on these cpu's like on notebooks.

Tomorrow I'm going to ask for another phone and see if I get the same temps, if not what do I have left flash a custom rom ? undervolt ?

I've seen some people checking the temp of the phone but only having as a referecne the external thermistor which is not an accurate way of measuring temp.

Basically I don't want to end up with a brick, as you know high temps on this Lead free solder BGA's, start to make solder joints brittle and crack. Then you come up with wifi not working, because the BGA chips's actually desoldered.

I couldn't place the link cause I'm not allowed to paste as a first time user, sorry

I am curious what network everyone with overheating issues is on? I am having no issues while on wi-fi. But major overheating issues while using Sprint whose 3g network is utterly deplorable right now. Another in my office has the same S4 on Verizon with no overheating at all. I believe the phone overheats in search of a better signal much as if it is roaming even though I show a strong 3g signal. As soon as I am back on wi-fi, it cools down.

That's all good. What about when you are playing games? The temperature goes up even without using 3G

Overheating

Sorry; I'm not a huge gamer. Use my phone mostly for work, productivity, email, messaging, lots of web, apps, etc. I do notice an increase in temps while browsing for long periods but nothing like when WiFi is turned off/not connected and using only carrier network. In that case, everything raises temps; syncing, web, everything! Love the phone except for that.

Overheating

So very true. Such a fast processor should expect to be hotter than the norm; especially under load. However, not at 54 c with an inordinate battery drain while doing so (see attached). This clearly has something to do with 3G vs WIFI. If one asks the phone to operate solely on 3G (whether by force or choice), this phone fries. That can never be a good thing with any phone or processor.

Should I install philz recovery I think CWM I got it's not philz. I'm only interested for now on checking the custom kernel to find if temperature ranges go down below. As arm cores work with less voltage.

hi,

the easiest way is to flash it via odin. download your desired kernel, and i assume u have downloaded odin3 3.04. switch off your phone, put into Download Mode (home button+volume down button+power button), go to your pc/laptop and start odin3 3.04. put the kernel .tar to "PDA" section without ticking or adjusting other option, and click "Start". after a success flash, your phone will reboot. you also can flash via CWM/TWRP. any recovery will do as long as it is not samsung 3e recovery. i used CWM because i don't like the touch version hehe..

about the temperature, i'm not so sure how was the figure (i haven't install any temperature monitoring app) but the difference after flashing adam kernel is noticable.. i will install cool tool and will report back after testing.
