What is your S4's temperature?

Mind to share? Dial *#0228# to show.
Here is my numbers(indoor usage) :
When idle: 24C to 27C (75F to 82F)
When general browsing etc.: 28C to 32C (84F to 90F)
When playing video or game: 34C to 39C (93F to 102F)

27C-28C idle for me.
28C-34C when just doing general browsing such as reading XDA.
35C-36C after about 5 minutes of light gaming (e.g. Candy Crush Saga)
Running Wicked v4 with included kernel, underclocked to 1674MHz, contained in a Neo Hybrid case.
Above temps while not charging. Charging temps are much higher.

Wow... I average between 75 and 85F (29-35C) under normal use/idle... I've seen up to 105F (40C) under heavy use or after flashing a ROM and the initial setup.

I think those temperature readings are for the battery. If you want to check the real time CPU temperature check out system tuner. Btw, you have to be rooted in order system tuner to access the temp readings.

Yeah i think those are their battery temp readings. My CPU has heated to over 70 degrees under heavy gaming, and averages 40's and 50's under basic usage.

+1 similar results here. Although just noticed the external thermistor reading from *#0228# is similar to cpu temperature but with lower refresh rate. It is on par with my idle temps but doesn't show real time hikes. So here are my external thermistor readings. While browsing on Wifi at room temperature, it is about 38-40 C and under heavy gaming it goes up to 48C (playing Real Racing 3 about 15 min)

If you are on stock rom it should work. Make sure to dial the exact *#0228#. There will be two temperatures on that page. One on top, which is the battery temp. And one on the bottom which is right under 'external thermistor'. I think, external thermistor reading is either the average cpu temperature or a sensor that is very close to cpu.

Yeah i'm not on stock ROM, but my kernel has a CPU temp reader that checks every second, and its currently at 44, under mild usage.

interesting stuff, I'm planning on buying a S4 soon

It makes me somewhat feel better knowing that mine is just normal like everyone else's.
However, this is really a too "hot" a phone for me. so I am dumping this one for something else.
It was fun ride, but it gets uncomfortable when walking with this little "heat radiator" in my pants pocket. For people having cold hands, it might be a feature, but, too bad, it is not for me. I might check out the Galaxy Tab 3 in few months.

Lol I'm running PAC man w/Chronic Kernel, Apex launcher.
Friday on one of the hottest days in Phoenix 116, in my car w/out A/C using I heart radio on my phone. The radio stopped, after a minute I looked down found it had rebooted it. So I went to the home screen where I have system tuner pro widget and the CPU temp was 200°F... oh crap, pulled battery out left it like that till I got home.
Got home the phone was still hot, so I put both the phone and battery in the fridge for 30 min. Installed the battery after retrieving it and the phone and crossed my fingers and made a prayer. Phone booted up and still operates as advertise:thumbup:.

From GT-I9505 Dial *#0228# I only see battery status and "quick start" button, so I used *#0*#, select sensor, select thermistor, "AP" column (= Android Processor Temp). Is that the same thing your looking to compare?
At boot: 31C
Idle: 36C to 37C
After 3min video playback: 45C peak

[Q] Normal/Excessive CPU temperature for S4 ?

Hi,
I'm using a Canadian Galaxy S4, SGH-I337M.
Rooted, running on Liquidsmooth 4.4.4 ROM. Also has Ktoonsez kernel. It is currently undervolted+underclock a bit, and is stable (I could overclock it, but I don't. No need).
Been wondering for a long time about the operating CPU temperatures of the Galaxy S4... Never had the possibility to do testing with CPU temperatures before. I do have a LG P500 that I have overclocked a ton in the past, still work just fine, but the LG P500 is old and do not support viewing CPU temperature, so it's my first time experimenting with that.
How hot would be too hot for this phone? There are several opinions, but never figured out if I... "minimize" the risks of my actual temperatures, for some reason. My laptop CPU throttle at 85 celcius for instance. While it's a phone, it's completely different.
At night, while connected to charger, it would be pretty cool, at 25-30 degrees when I wake up;
I would say that most of the time, my CPU is running at 50 celsius, and rarely ever exceed 65-70 under normal use, or even gaming. Plus, the CPU is undervolted and a bit underclock, so I do feel like it run cooler than usual.
Quoting Meowmix from Rogers forums:
It varies on the usage of everyone else & how you handle the phone ( cases & such). Also if you are in extreme heat or having the device in direct sunlight.

So, the case does matter? I do have that Otterbox case which is pretty tight and enclose the phone pretty well, I would believe that the phone would get less.. air.. but I mean, it's just a case, didn't thought it would affect much..?
Quoting Ahmed from AndroidCentral Forums, I would say that I have a quite similar situation.
No, just when i ran AnTutu when it runs the 4 cores at the maximum frequency the temperature is between 80-91c, and at normal use while surfing the internet the temp. 45-55c and the battery reaches 38c after an hour of continuous using.
Click to expand...

I CAN reach 80-90 celsius, but only if I really want it to happen. 38 celsius for the battery is also correct, I never exceeded 41 degrees yet, on any Android phone (I don't know the dangerous battery temps.. But when I reach 40 degrees I try to put it down as fast as possible). With benchmarks, usually at the max frequency, or testing my undervolt with Stability Test, I CAN reach 80-90 celsius, which look really high. Additionally, I would remind that I don't overclock, and the CPU is undervolted so seems a bit cooler.
So on AndroidCentral, this is the reply Ahmed got, from "CR6" user:
I had to use my temp converter to look up & convert them to Fahrenheit. 80-91c equates to 176-195 Fahrenheit and that's extremely dangerous. These temps will not only physically burn you, but will fry your phone if you continue using it at these temperatures. 45-55c equates to 113-131 degrees Fahrenheit, and that is normal under really heavy usage. Optimally, you'd like to keep it at 38-45c. You may have a defective device if you regularly see temps over 80c and I would advise checking on a replacement.

THAT dangerous? Well, I don't phisically feel the heat - I do feel it, but since I have that phone case, that doesn't hurt at all. But like I mentionned, I never reach 80 celcius or more unless doing benchmarks. Usually I never exceed 65-70. But still it left me wondering - Why does Android allow such high temperatures in first place? Isn't the system suppose to shut down at some point in case of danger, and when?
I've also experimented with thermal throttling in the Ktoonsez kernel, and the throttling values of the ROMs. Touchwiz Stock ROM with DVFS disabled, seems to throttle at 80 celsius, look decent. Liquidsmooth AOSP ROM, stock kernel, does not seem to throttle at all (Huh)! Once, and that was exceptionnal, I've reached 100 CELSIUS using Wifi, connect to a charger after like 2 hours, room temperature was very warm, was not surprised, but when I noticed I reached 100 CELSISUS, I was WOAW, I should shut down. I did reached 100 degrees again, using Stability Test at max frequency after a few minutes. Needless to say I manually stopped the test, because I had no idea how much heat the phone could handle...
So been aware of this, "Ktweaker" app, for the Ktoonsez kernel I use now, does have a thermal throttling option, but I wondering which thermal value should I enter for best "performance"? Default was 70 degrees, I set mine at 80, I've heard of people even putting 90 for the same kernel. Besides, maybe I worry about it too much, because in no way the phone should exceed 70 degrees celcius under normal use anyway, or even gaming. Only way to reach insane temperatures would be benchmarking/stress testing...
Still, first time seeing these CPU temperatures also. I've overclocked my LG P500 several times in the past, dealing sometimes with random reboot, so make stability/overheating questionnable, but the device did not supported seeing the actual CPU temp. So I don't know which temperatures would be considered normal - probably, nothing above 75-80, correct (For the Galaxy S4, actually)?

I do know it can run up to about 180 before hitting critical and shutting down
Edit: its about a 75 degree ambient temp where im at.

At which point is the device supposed to shut down? Is that in the kernel or a hardware CPU trigger? Because heck, I've reached 100 degrees 2 times, I mean, how far/close was I from a shut down? I'm quite surprised.
I've also read of people complaining of S4 overheating, especially maybe after it was released - It's possible that it heats up more than other phones, but honnestly I have no idea.
Thanks for your answer =)

Going thru this exact same thing. Same temps. This is not normal. Mines just started happening one day. Idk how or exactly when

Thank you for your answer;
Used to think some temps look normal to me - Besides, since I've undervolted last week, it's stable and run cooler, maybe better battery as well. I never can exceed 70 degrees even when gaming I supose..
I can reach 80 degrees, but only when benchmarking or stability testing, so I'm not worried, but I do wonder;
I've reached 100 degrees 2 times, once while doing a stability test at 1,89 GHz for like 5 minutes (or more), I had to manually stop. And last time was long ago, watched YouTube videos in bed, like under covers ha, maybe as well connected to charger. Not even surprised I've reach such temps after a while in such conditions, under covers, just no air (Used to do it with my LG P500 too. While I never was able to see the CPU temps on this device. Even then, LG P500 still works, but guessing build quality was much better). Needless to say I was like WOAW when I've noticed 100 degrees, and just put the phone down. Probably went from 80 to 100 quickly, didn't noticed that fast. But yeah, that 100 degrees was.. almost expected under such conditions.
I just really wonder about thermal throttling. Like I've mentionned, stock Touchwiz with DVSF disabled seems to throttle at 80, while KTweaker app for a different AOSP kernel have the default temp limit set to 70. Liquidsmooth ROM, AOSP, does not seem to have a throttling point, since I've reached 100 degrees 2 times with it (Don't intend to test 100 degrees again, huh). What would be the maximum ideal temp for throttling? Maybe I think about it too much, since under normal circumstances, I never exceed 70 degrees, besides benchmarks.
Also wondered at which temp is the phone supposed to shut down... 120 degrees?! XD Because 100 seems ridiculous to me, probably is, but yeah, my laptop throttle at 85, and it's a laptop (Intel Core i3) - Can't imagine a phone going any higher without any risk.
Thanks for the feedback

Solution to reduce thermal throttling on Nexus 5X?

Is there a way to reduce it? My phone slows to the pace of a sloth far too frequently and it seems correlated with temp.
I'm assuming that's the cause because when I look at the CPUs in CPUz the last two go down to 633MHz when things are getting slow. Also seems worse with a case but could be my confirmation bias. This is particularly apparent with the camera, Maps, and when coming out of doze.
Is there a more conclusive way to figure out what is causing my Nexus 5X's occasionally brutal performance?
Sent from my Nexus 5X using Tapatalk

Well, what exactly are you doing with your phone that's causing it to throttle itself? I think with a stock kernel the phone begins to throttle and eventually shut off the Big cluster at 36 or 37 degrees Celsius (someone correct me if I'm wrong). If you flashed a custom kernel, most here have had that limit raised to 46C.
Last weekend I used my phone quite a bit for strenuous tasks including Navigation, Google Maps, lots and lots of pictures and 1080P video. The phone got noticeably warmer, but when I checked my kernel management app, the CPU temperature wasn't even close to the throttle temperature. Unless you're gaming or constantly benchmarking your phone this really shouldn't be a problem. Especially when coming out of Doze. The phone doesn't immediately enter Doze, it waits a while and there are factors that play into its decision to even enter doze in the first place (like laying on a flat surface for X amount of time). So when a phone is exiting Doze because of your input (turning the screen on) the CPU should be quite cool (maybe 22+ degrees). There's no thermal throttling there. The Big cluster shuts off when the screen is off for the sake of battery life, so maybe the lag that you're experiencing stems from the lack of the Big cluster being on for the first second or so when waking the phone back up.
I'll agree that the SD808 isn't a stellar chip; maybe even embarrassing. It's not blisteringly fast, but it certainly isn't slow. There are ways to speed up performance and improve battery life at the same time, which I'm sure you'd appreciate. Unfortunately you have not specified if you're running a custom ROM or kernel, so that's pretty much all the advice and information I can give you right now. But, if you're currently running stock, I'd highly recommend you unlock your bootloader and try out some of the custom (and more lightweight) ROMs that this community has to offer as well as some great kernels. That should make a noticeable difference right off the bat. Then you can dive into the nitty gritty details of tweaking and whatnot if you desire. Check out the links in my signature as a starting point. If you're looking for optimization and speed (like I do) then you'll be impressed.

Thanks for your reply.
I switched to ElementalX about a week ago and it may be a bit better now but it's hard to tell. I've also been using a spigen slim case, maybe that is causing heat to accumulate too.
I don't game. My usage is Maps, Facebook, Snapchat, camera, chrome, hangouts, Spotify, and textra.
I use greenify and amplify as well on xposed. Disabling xposed doesn't seem to make a difference.
Can you confirm that ElementalX throttles at 46C and stock at 36C?
I'm interested in your recommendations. When running geekbench it takes about 9 minutes for things to really slow down.
Sent from my Nexus 5X using Tapatalk

If you search the ElementalX thread you can see that the developer, Flar2, was getting very frustrated with the thermal throttling on this device (others were too, as well). You can read through the progression and, eventually, the decision to apply a "thermal fix" or raise the thermal throttling limit. The threshold is 46C now. Confirmed. The stock thermal throttle threshold is 10 degrees less than that from what I've read. I also remember reading that Franco did a fair amount of research into the throttling issue and found that the CPU was capable of going over 50C with no issues (but aren't recommended), so the limit in place now by the ElementalX kernel is a safe one that shouldn't be exceeded. He probably didn't make it any higher so he wouldn't be found liable by any users if they overheat or damage their phones.
I have no experience with xposed and everytime there's a compatibility issue, hard reboots, etc. it's always because of Xposed. So.. Yeah.
I also do not use any tweaking apps that supposedly save battery or whatever. I let the operating system take care of that. I do use the L-Speed app (again, in my signature) to disable certain things like debug logs and what not to speed things up slightly. Again, I highly recommend trying Ubermallow and Phasma Kernel as those have been my choice, after trying many others, for some time now. Also, I'd look into the interactive governor tweaks after you've settled on a ROM and kernel combination that you like. That's where you can fine tune the way the CPU governor on the phone behaves and can really make a difference in battery life and fluidity of the device.
Lastly, a case can make a difference with cooling but I've never really found it to be an issue. Maybe I'm just not hard on my phone enough.

Google just agreed to take back my device so I only have a few days to try things and make my decision on whether to keep the phone or not.
Thank you for your thoughtful responses and suggestions.
Since I started using the phone outside of the case it actually seems much better.
Regarding the extreme slowness coming out of doze, it only occurs when in doze for a long time. Presumably because the phone tries to catch up on all the sync activity that's been paused for the last 12h or so.

I think I'll try your suggestions and remove greenify, amplify, and xposed to see if things improve. I do agree that the system should be managing those things.
Sent from my Nexus 5X using Tapatalk

Yeah, give it a few days. There are many ways to combat the throttling. Got my phone to 41C today while using it out in the sun. The Big cluster is limited to 633MHz at 36C and shut off at 41CC. The 46C built into the kernel is most likely for the LITTLE cluster to start getting throttled. Check the attached pics below.

Thanks. Btw what ROM and app is that?

ROM and Kernel are in my signature. The app for managing the kernel is Elementalx Kernel Manager and the app to add CPU usage overlays and stuff is called Trepn Profiler.

Sounds like the opposite to me, the phone might be slow because of software on the device not playing nice which causes the SoC to work over time (normal computing + rogue app computing) and can cause the device to over heat and throttle.
There's no reason the device should be slow after a period of doze. That tells me the device is having software caused slowdowns that are not related to thermal throttling.
It takes roughly 12 minutes of 100% sustained load (only synthetic benchmarks) to throttle the 2x A57 cluster, and I've never seen the 4x A53 cluster throttle under any conditions including hours of heavy gaming they stay at 1.4Ghz at all times.

Yesterday I was using GPS to drive and Spotify was streaming. The phone got really hot and unresponsive and Spotify began to stutter. Was unable to even launch textra to text someone.
This of course only started maybe 10m into the drive. The phone is fine while cold.
Maybe I have a defective device but my benchmark stress tests give similar results to other people.

this is consistent with my experience. GPS and spotify (actually almost any app used concurrently with spotify) will cause the phone to have horrible lag.
also, don't text and drive

Interestingly, today when the phone was on battery saver it seemed much faster. Maybe more throttling could help things more than less?
Of course not exactly faster, but more consistent and no unbearable lagging.

Yesterday I flashed the stock firmware files other than user data. Unfortunately I lost root and it seems like I now need to reformat data to get TWRP going again but until then I'm fully stock. Does anyone know a way around that?
I haven't done enough testing to be sure but things seem to be running more smoothly for now than they did with root and ElementalX 1.06. However just writing this i can feel the phone heating up and becoming less responsive. The bottom 2 cores are offline with SoC at 36C and CPU at 56C when I switch to devcheck to check. Other 4 cores at 1440MHz.

I've been having issues with thermal as well. Installed ElementalX along with the governer tweaks GhostPepper profile. When charging (this makes the device really hot) music begins to stutter, coming out of Viper4Android.
When not charging, slow accumulation of heat makes music stutter, same software used. Go figure. Maybe V4A is too demanding on the 808 chip, but I fear if this doesn't cut it, then I'll have to switch phones the next chance I get.
Oddly, this happens when screen is off - the music stutterings. I've thought about Doze and battery saving apps, and have disabled Doze for V4A through the battery optimize pane.
The phone constantly loses battery, around 2~5% an hour, I know thats not too much but my previous phone lost about 1% every three hours. This was a Note 3 Neo by the way. Installing Xposed and Amplify, Greenify and PowerNap should help, but I've had stability issues when using xposed. Maybe later.
Oh, and one last thing. My phone's thermal limit is set to 55 degrees Celsius, but it still feels like it throttles at around 39 or so. Maybe EX Kernel Manager isn't saving the changes, but either way... It throttles too much!

That could be because of the custom software and CPU tweaks or your V4A installation. Using those settings always has the potential to cause issues and I would troubleshoot there first.
Minimum CPU performance with stock settings is 4x A53 cores at 1.44Ghz which is still fast. If you've ever use one of the more recent Moto G devices you'd know it doesn't stutter playing music when it's cold and neither does this device when it's hot.

Setting the throttling temp limit to high will decrease performance, see here for details:

is there something wrong with my Note 4?

Attached below is a picture of my Hardware activity while playing Power Rangers Legacy Wars which admittedly is a graphically intense games but I'm worried that the temperature of the GPU and or CPU is getting too high. I want to make sure my Note 4 isn't getting too hot here is the picture:

I need somebody's help. The coolest my Note 4 seems to get is about 53 degrees C and that's when I turn it on after it's been asleep on my desk. It is not a rogue app or anything like that because I have done both Factory resets and I have install custom roms, so everything has been factory reset multiple times. The water damage sticker indicates no water damage whatsoever. I know phones can get hot when gaming, my Note 4 gets to anywhere between 70 to 85 degrees Celsius and I am just wondering if that's normal I reduced my screen resolution to 720P and disabled two cores of the quad core processor and it does not seem to help one bit. Is this temperature normal or do I need to get rid of the phone?
PS when doing normal browsing it seems to hover around 60 to 67 degrees C
And the battery does not seem to go over 37 degrees Celsius

If you're worried about high temps during games I'd recommend turning the max GPU frequency down. It significantly reduced my temps and I didn't notice a significant difference in gameplay.

Thank you for your response. I have done that and it does not seem to make a difference I'm still getting CPU and GPU temperatures in the high 70s to low 80s

Would you mind posting a screenshot as above with the same overlay? How long are you playing before it gets to this point? Have you adjusted throttling temperatures?
Edit: Saw your other post and wanted to add some troubleshooting. When you open up TWRP and do a file transfer or backup how hot does your phone get? Mine would get pretty hot to the touch, but I don't remember it getting above 80 C.....
The temps you showed in the other thread are definitely not "normal" from my experience with day-to-day use. Did you ever look at the task monitor app I linked to?

Sure I can take another screenshot. How do you want it? I did check out that app and the only thing that I saw was that it seems as though my CPU cores were always running pretty high but I didn't see any applications taking up and unusual amount of processing power. The temperature ranges to about 60 as soon as I open a game for the most part and continues to slowly rise from there. Yes that's about the temperature I get everytime I go into TWRP. I don't even have to be doing anything I'm just open TWRP work and that's about the temperature I get

Sorry, I posted that before I noticed your updated screenshot. I was just curious if limiting the GPU made any difference.
Honestly I'm running out of software suggestions. Do you have some sort of case/screen protector that could be affecting it? How hot us your screen (qualitatively)? I just looked at an old video I made and my phone was 52 C in TWRP, which isn't too far off from yours so it might be fine (as I said my phone screen would get too hot to touch at times during intense games). But if you look at kernel adiutor and see that the CPU rarely drops to the lowest frequency/deep sleep there's probably something wrong (unless your screen is constantly on). You could try a different kernel or governor, or check an app like gsm battery monitor to see if GPS or something us hogging CPU time, but I don't really have any more ideas. (Although I did used to cool off my screen with a wet towel when it got really hot)
Just to confirm: you're running a Verizon note 4 right? (Have to ask)
You've updated the modem to the correct version through Odin?
You're on the proper bootloader?

First of all thank you for your help once again. I don't know how to measure how hot my screen gets I don't have any tools that would allow me to do that I do have a case and screen protector on but it doesn't seem to be any worse than it was before I put them on. Yes I am on the correct bootloader and I do have a Verizon Note 4 running the nseven ROM and I am on the correct modem. I'm willing to do anything at this point. This is the second note 4 I've had with this issue and I just want to be able to use it. I want to be able to play my games and stuff you know. So if there's a literally anything I can do . plus I don't really have money for a replacement

I found this: https://forums.androidcentral.com/s...bout-cpu-temperatures-according-cpu-z-s6.html
Which shows some pretty high temperatures during heavy and normal loads for a G4 and some other forum discussing how their note 4 would reboot due to overheating. Since you're not experiencing that issue I'm not sure you need to worry too much. Your processor should be throttling itself if it's getting to hot to make sure it doesn't get damaged. I'd try to make sure that you limit your gpu to around 300 and then just make sure your CPU isn't overclocked and you will probably be fine. My note 4 would get so hot that I couldn't touch the screen, but it still ran like a champ and never rebooted on me. The only thing that is concerning is that your CPU clock specs aren't sticking, but you'll need to read around for how to fix that since I've never had an issue.

Okay well that makes me feel a whole lot better thank you. According to GSMArena the processor speed of the Note 4 is 2.7 gigahertz and mine is currently running at 2.4 so while it is a little upsetting that I can't bring it down any further, at least I know again according to GSMArena that my processor is not overclocked. Thank you for everything

Heating no matter what - getting hopeless

Hi All,
I'm using my Z2 since 2017 Jan. I've unlocked the bootloader after a year (non-treble), and since then I've used AEX, Bootleggers etc. Last week after i've switched to carbon rom, I've noticed heating for normal usage. Normal multitasing (Facebook, Chrome, 9gag app) = 45-55 degrees of Celsius. I've switched between a couple roms, no change. This is when I've decided to start over - ZUI 1.9 - bootloader lock then 3.5.X for the baseband, then bootloader unlock, new TWRP, Treble this time. I've tried AEX 5.8 and now ArrowOS, but no change, when I wake up the phone 30-32 C, then when I open something up 40-45-47 very quickly. Is there a way to fix this, or maybe I have HW issue?
Thank you

Try using the sun cooling mod

Sorry to contradict, its not heating, its warm, but not something you can call hot.
Facebook, Chrome, 9gag app

I haven't used 9gag, but both FB and chrome aren't quite resource friendly to start with.

The issue is more or less same here too.. When I am using my Z2 Plus outdoor under direct sun light and Indian summer. Even basic idle phone calls would warm it up. Playing PubG outdoor under sun light feels like holding hot metal and burning my fingers.
Is there a way to fix this

There are thermal mods available for aggressive throttling of CPU for achieving lower temps. You may also try using a kernel which supports editing on fly, like nameless (using kernel editor app from play store) to underclock your CPU / GPU for less heat.

Are you mad or what? 45-55 degree celcius is very hot.. my phone is always under 40 even under sunlight with extensive video playback and browsing and around 45 when playing pubg.. this is what i can call warm.. not 45-55 with light use, i suggest to use characteress's thermal mods to cool down your phone

Pardon me for being a noob, but I am unable to understand how can a software cool down a phone below ambient temperature?
I am from a part of India (Kolkata) where often Ambient temps hit 45c outdoor !!
Some input would be really helpful.

I agree that ambient temperature plays a big role in device heat management, but software(thermal configurations) play a huge role in regulating temperature, you can experiment yourself, just underclock processor in kernel adiutor to about 1.8 ghz and heating will be reduced significantly, our device has sd820, which is known to have heating issues in many devices. It's a quite powerful proccesor(2.15ghz) , so when all the cores are performing at their highest (like when playing pubg) ,heating is bound to happen . So by underclocing to 1.8 ghz you can reduce it. And regarding thermal config files, they are just files that throttle the performance of the device when it's heating, to cool down, sure your device's performance will take a hit, but this will cool down your phone

Thanks for the long reply. But being a noob it seems I am still unable to find the answer for my question.
How can a software cool down my device below ambient temps?
As far as I know, no software tweak can even push device temps below ambient. And ambient being 45c, device will for sure run a few deg over that. No matter how much tweaking is done.
So not sure how I am "mad" for calling 45-55c range normal !!
