Got My N5 today, its awesome,
Looks like the performance is so so, the phone heats up too quickly and CPU performance goes down,
If I do Antutu when its warm I get less than 20K in it
If I let it rest for some time and then do it I get a score of 25+
Looks like the device has heat issues
are you guys facing the same issues?
Two-part solution: Stop running benchmark tests and flash Franco kernel.
And, search before you post. Lots of threads on performance benchmarks
I see so many people who care what a benchmark score is.

its not a heat issue. it will get hot with use, especially with antutu benchmark, its a 2.3ghz quad core phone without an active cooling system, what do you expect? anyways, the reason performance goes down when hot is because of heat throttling. your phone does this when going over a certain temp. it drops the cpu speed and number of cores used until it cools down. there are ways around this. you can root your phone and flash a kernel that lets you disable thermal throttle. then all your left with is the safety reboot temp of 100C. when reaching this temp, the phone will automatically shut down. or you can put your phone into a freezer until the cpu temp is below 10C, then run the benchmark.
Nexus 5 operating temp 80-95*F, up to 100-105*F with camera use. Is this normal? I do live in asia, where it's hot right now, 91*F.
*if there is already a tread regarding this issue, pls feel free to correct me and lead me to the right place. tnx.

Hi,
Absolutely nothing wrong, plus with this room temperature... (about 35°C- 40°C), it's nothing. I guess you mean about the battery temperature...
Search in this Q&A section for "heat" or "overheat" you will have some thread about CPU temperature and battery temperature. In any case there is a thermal protection: thermal throttling then...

Thank you sir
All phone when using the camera and even recording heat up as the camera module and image sensor has to work hard to lock AF and other things
my iPhone 5s gets hot my HTC one gets super hot, my nexus 5 gets hot
So I finally decided to root my G Flex 2. I've been talking about disabling cores for a while. Thought it may help the thermal throttling issues. Once I rooted the device I downloaded "Multicore CPU" and started disabling cores in a couple different combos. I've finally settled on disabling cores 4 and 7. Since I disabled the two cores heat has not been an issue and cores 5 and 6 are running at 2ghz. Reduced lag, and benchmarks have shot up some. Personally enjoying the lagless environment. Figured I'd post my experience with this. I'm hoping overall battery life will be better as well. Won't know for a day or two though. Oh and it stays cool while charging and in use. It used to get really hot before.
Anyone else have any experience with this?
So here are results of disabling cores and thermal throttling or lack there of now.
I also want to note that my benchmark scores were lower than the note 4 after some updates until now

My core 4 and 7 were already disabled but still very laggy... And it heats up really bad...
When do you get this overheating issues? My flex just gets warm using Chrome so i use the lg Browser now. And whats your Firmware? Still stuck in c with all Cores enabled

4 and 7 are not active unless 5 and 6 are under heavy load I believe. I've just made it so they never turn on.
I'm also using software ls996zv5

Ok on YouTube mine gets a bit warm but not as hot as in Chrome (on normal sites, nothing fancy). Watched twitch in Full hd for an Hour yesterday without any heat...seems like some Apps are better optimised for the sd810 than others
Are we getting a sd808 by disabling 2 Cores?

It looks like SD810 is a peace of crap. The Flex 2 compared to my Oneplus One is like an Opel / Vauxhall Astra compared to an BMW X6.. Very disappointed..

Ok getting a lil bit off-topic here ...i am Happy with the Phone so far, way faster than my old razr i Think Updates will make this Baby Fly (even more)
So Keep us updated with your experiences as hexacore user i am very interested in the Battery life and Real Life Performance !
808 with better GPU lol

I am also coming from oneplus, I must say you are sadly right. Newer is not necessary better in this case.
I hope with some optimalization this can be a Ferrari.
I was already let down by LG a few years before, let's hope it is not the case now.

Hope that with android 5.1 everything will change for better.. :fingers-crossed:
I have the AT&T version of this phone and for me cores 4,5,6 and 7 are always on except when the cpu goes above 36C then cores 4 and 7 automatically get disabled. I'm also not experiencing any lag and it's actually very smooth and fast. It also doesn't get very hot unless I run Antutu benchmark like three times in a row. What kind of CPU temperatures are you guys seeing when your phone gets hot?

You can download Cpu Temp from the play store or I also see it in kernel apps like Trickster MOD.
My galaxy S4 used to get warmer then this phone when watching Youtube or browsing in Chrome.

Runs at 44C after playing games for a few minutes.

The highest i've seen is 47C and it does make the phone feel warm but not any warmer than my Galaxy S4 used to get.

My phone is around 40C when playing games or browsing the Web.
With another firmware wersion I was getting temperatures around 48C. That was Killin the battery in minutes.
This is what I deal with when all 4 cores are running
I just received my GS6 like 2 weeks ago and ive obviously been using it. My question is Is it ok for the right edge of the phone to get somewhat hot and for the CPU to reach 70°C? (Checked using CPU-Z, I know CPUs are supposed to get hot but this hot on a phone?) from using apps such as snapchat or listening to music and chatting or even the camera for a few minutes? Coming from the original Galaxy S, this doesnt seem okay to me.
EDIT: It only reached 70C only once. The other times it got to the 60s.

That's definitely not good, my max temp has been around 50~ish, if I was use I'd keep a close eye on it and if it continues like that go to the store you bought it and tell there's a fault with your phone.

Mine is around the 40s as well, it isn't necessarily bad or anything but 70s that's like overheating, idk what the max temperature is for the Galaxy S6 but I've got the feeling your coming close to it

I know right.. specially for a mobile device 70 is kinda pushing it. I'll use the device in safe mode and see if it overheats and report back.

Wasnt able to measure temperatures but it did feel pretty hot (the right edge where the power button is) after using the camera for a bit, uninstalled a few apps just in case and ran Geekbench 3 and here are my scores, and compared to other s6s its quite low
Single core: 1353
Multicore: 4383

The easiest and most basic way to fix the Galaxy S6 overheating issue is to restart your Galaxy S6. Just switch off your Galaxy S6 phone. Wait for a few minutes and then turn it on again. It is quite possible that this small restart might fix the Galaxy S6 overheating issue.

Depends on your room/surrounding temperature as well! In summer when it was like 33-35°C, my cpu never fell below 45C and battery always around 28-31C idle!
I think cpu starts throttling at 80C. Try Greenifying some apps as well!

ohhhhhhh . i wish any expert will give the solution of your problem soon
Install titanium app and freeze any random rogue apps. The CPU going to 70degs is not a bad thing usually the max temp would be over 100degs. Do you have the charger plugged in and you are using the phone, and you are getting those high temperatures while doing this? If so switch to a normal charger if you want to use your phone while it's plugged in. Fast charging while bring more power/heat to your phone so be aware of that
Hi! I have G930F. I installed TWRP and installed DevBase v5.7 rom. When i flashed TGP kernel and played heavy game while 10 min, phone gets so hot. When i cheked battery temperature its showing 43°C. It is normal?

Hello,
Exact same problem here.
I'm running latest LineageOS official.
What app are you using ? I can't find that one called "little" on the play store...

Thx, well it's not exactly the same problem as you have since my CPUs are running in low power state when the phone is not used.
Anyway, when I start browsing the internet, the phone gets hot and when I'm playing games, it just gets super-hot. (not in charge while using it btw).
Previously, I had a Nexus 4 which is famous for its overheating problems, but the S7 is worse.
This, the ill placed speaker, the poor quality of the AMOLED, I'm so disappointment with this phone.

The AMOLED screen on the S7 was widely regarded as the best screen on a mobile phone when it was introduced.
You're running an unofficial ROM + kernel and running into problems and are blaming the phone? Lots of people seem to hold LineageOS up as the solution to all problems, but on many devices it seems to be a giant hack.
This screen is a piece of **** (mura effect & spots when lowering the brightness), my Nexus 4 screen is at least 10X better.
I'm running Cyanogenmod/LineageOS since the very beginning, never had this kind of problem before...
The S7 Exynos phones do tend to get a bit warm if you're browsing certain websites, Facebook and streaming, and it'll get hot if you're playing resource intensive games like GTA & Bully. That's what happens when your device's CPUs can reach a max clock speed of 2704MHz. Take a look at what apps are running in the background first.
I'm only able to read the battery temp sensor, no other sensor available despite having tried a lot of monitoring apps.
Idle temp : around 29-33°C
Heavy use : up to 45°C
Past 39°C, the phone gets really uncomfortable to use.
I did further testing with another S7 (carrier firmware, brand new), launched a stress-test app on both phones at the same time and after 15 min, mine is 4°C hotter (battery temp). It's not really relevant, maybe due to my tempered glass preventing heat dissipation or some LineageOS optimizations, I don't know. Anyway, the S7 feels way hotter than my previous phones.
it's strange that power user/advanced user have to complaining about overheating and comparing with other brand when they are running unofficial software and kernel. and i think the word 'overheating' is about the cpu/chipset not the battery. *correct me*

Yes but I only have access to the battery sensor. The frame is hot on both phone tough.
i have a snapdragon version of S7 and i don't think exynos version have overheating problem running on official firmware. running Oreo right now and still don't have such problem. and FYI using the phone INFO apps (google playstore), i can see the temperature of the cpu.
