Hi folks, I'm torn between the snapdragon 636 and 845. I know 845 is the more powerful chip but I'm not exactly a power user.
I play games which runs well even on the snapdragon 625 and I love how the chip stays cool even with extended gaming sessions. On the other hand, I've had bad heat experience with the older 8xx series of snapdragons. No matter what I do they heat up so much till I can fry an egg with those phones.
Now the hard decision comes because the prices of Max 3 is just a little shy of the poco f1. I'm just sick of heat and would like some hands on feedbacks from the excellent community here.
Thank you so much!
I have the Max 3 and I have no problem with even higher end games at max settings - mobile CPUs have gotten so powerful that there aren't many things around that can actually challenge them anymore, even at the mid-range price point. I would consider myself a power user, and the 636 keeps up with everything I do with zero issues. I would recommend the Max for it's huge battery and reasonable screen resolution - anything above 350ppi is a waste anyways, and the Max 3 has exactly 350.
Hi misterk267,
Yeah, I certainly like the new format of the Max 3 and how much the battery can last before I have to charge it. Problem is the pricing is just so close to the Pocophone and it doesn't come in 6/64GB configuration.
Since we're on it, I just like to know the heat produced by the SD636. Does the SD636 ever throttle? I'm assuming the SD845 does throttle under extended continuous usage beyond 30 minutes.
I pre-ordered the Global Rom Mi Max 3 @ $290 before the Poco F1 was announced. As I am still waiting for it to be shipped, I have been very torn between it and the Poco F1 and wondering if I should cancel the Max 3 and rather get a Poco. I have to say that I don't game at all, so a Flagship chip like the 845 would probably be wasted on me. While the Poco has a slightly better camera, I am sticking with the Max 3 because of that massive battery life, bigger screen for media consumption and no notch. I'd love to rock a flagship chip and buy into the Poco hype (which is justified - amazing bang for buck), but I have wanted to own a Mi Max device for so long, so will have remorse if I don't hold out for my on order Max 3!
I cant get my 6GB/128GB .eu ROM Mi Max 3 to heat up no matter what I do to it, PUBG while charging no bother, it doesnt even get warm.

Yeah, that's the thing I love about the 600 series of Snapdragons. My worry is SD845 heating up too much; it happened on my old cellphones with the older 800 series of Snapdragons.
However, the SD845 is on 10nm while the SD636 14nm. Max 3 has a larger screen that makes typing much easier, IR blaster and battery that allows me 2 full days of usage.
Really torn between Pocophone and Max 3.
Maybe I must buy both
if you need root go to pocophone as xiaomi has increase the waiting time for unlocking bootloader for their device , but not with pocophone.
I dont see any torn between these devices:
- You just see the torn because you want the best of both (battery, screen of max 3 and the performance of poco).
- IMO, after purchasing MM3 (went up from MM1) then continuing found out Honor play, Honor note 10, Poco, etc. I dont have any regret or think back because:
-- I defined clearly the reason why I chose MM3:
1/ great battery
2/ huge screen
3/ the performance which is enough for my daily use.
4/ Not too expensive.
So you should only feel the torn when MM3 cannot afford for your daily use and there is another phone with the same price/better specification or lower price/same specification, something like that.
Imagine that after buying poco, there is another phone which is even better than Poco, how do you think at that moment? Sell poco then buy that better phone?

I hadn't really thought about it, but now that you mention it I don't think I've ever felt my 6/128 Max 3 get warm at all. That being said, I've never had an SD845 device, so I can't comment about how they compare.
For what it's worth, my 636 hasn't failed me yet in the gaming department. I can run strangers wrath with all graphics settings maxxed out, and that's the most graphically intensive game I really play. And it STILL doesn't get hot.
Unless you want the SD845 for bragging rights (totally understandable!), I'd advise you to get the Max.

You can try this app.
https://play.google.com/store/apps/details?id=skynet.cputhrottlingtest
Look if the temps rises and if the graphs dip after the test has been running for a couple of minutes.
If they do that indicates that the one or more cpu cores are being underclocked after a while to restrict heat output.
I have done this on my phones with different cooling paste to test before and after results.
I did look at some of the teardown videos on youtube on the Mi Max 3 and it has a square almost dry grey probably dow corning preapplied cooling paste.
It looked dry and teared in the video so its not very good to begin with.
The cooling paste is only for the RF shield.
Under the RF shield is two blue thermal pads. One big for the cpu and one smaller for the radio I think.
None for the storage chip.
Would be interesting to see if changing the cooling paste makes any improvement..I'll wait until my warranty expires before I open my Mi Max.
Under the RF shield with the pads, one alternative is to put copper thermal shims to make contact with the rf shield or a better quality thermal pad with higher thermal conductivity on the cpu and radio chip

Nice share.
I ran the test for 5 minutes, and the results show throttling to 76%. That being said, the end experience is what really matters - I've certainly had heavy gaming sessions that lasted well beyond 5 minutes with no slowdown, though I have to wonder how Xiaomi's gaming optimization affects throttling when active. It's also possible that 76% is still enough to run these games. I'll add the app to the list of games and run another test in a few minutes.
Here is a screenshot.

Yes this app puts a load that is kind of balls to the walls..you rarely ever push the cpu this hard in real life even in games on android.
But it gives an indication in which direction you might want to look at look at. Its a little on the warm side but its okay.
Its not going down below 50 to 40 to 35%. That would be a significant warning sign for heavy thermal throttling
Edit:
The screenshot is totally passed. Nothing wrong about that.
Starts off way up in the green and hovers in the high yellow and kind of stays there for the duration of the test and doesn't drop any lower than that.
If you see any low points that quickly rises back to its normal state and you know you touched the phone that might be why.
If you accidentally touched the screen or give the phone any additional stimulation it will decrease the result and it will show up at the given time on the graph.
Out of curiosity - you said you have run tests on other phones before and after swapping the thermal paste - have you seen any/significant changes in throttling when doing this?

No just slight. The top values are the same.
Just that it takes longer for the cores to start underclocking.
Of course the phone don't have any fans to exhaust this heat so you can only prolong the time before and to when the cpu cores are starting being underclocked. That's where the limitation comes in.
The cooling paste only improves the thermal conductivity so it reaches the far end of the phone quicker than with the old crappy cooling paste.
So we cannot compare this to a laptop or desktop computer where you change the cooling paste and see dramatic results because you have fans that push the heat away from the computer.
My honami dimmed the screen before and it took almost 5-6 minutes until it started feeling a littler cooler and the screen brightness slowly coming back to its original state.
And I couldn't see the damn screen! It was like the screen was off.
Now the phone gets VERY HOT!! and the screen dims. But the brightness returns after just a minute and the phone is already cool to the touch.
So the new cooling paste helps to quickly collect and move the excess heat. If compared to the old cooling paste that did not move the heat out of the way and the phone did not feel warm other than right above the motherboard while now the whole phone is scorching hot indicating that all that heat that collected at one spot is now helped to spread out to the whole area that is thermal conductive.
Same goes for my Z ultra but its a larger phone so it don't have the same issue as the smaller honami.
And the smell of a hot iron is gone too. You know the smell when you heat up your clothes iron and it starts smelling like hot materials.
Very hard to explain. But that scent is completely gone now when the phone gets very warm.

Thanks for the explanation - even if it does not give dramatic results, it's still pretty interesting to see what happened when you made the modification. I don't think I'd ever have the courage to try something like that :crying:
How can you be torn between a 6 and a 7 inch screen? They are completely different beasts! Decide how big of a phone you can put up with (bigger the better) and then buy the corresponding one.
No processor could make up for a smaller screen for me.

I wish there is a Max 3 with SD660 instead :fingers-crossed:. I really love the Max series for its battery, it's actually lighter to carry a Max phone than any other phone with a battery pack. The only thing is the weight; it'll be great if it's 200g but I prefer a larger battery than not.
I wouldn't hesitate to buy a Max 3 if it weren't for the price; it's almost the same as a Poco and I really prefer a 6/64GB configuration for the Max 3.

Wow, great post! Have you had the chance to do this with any SD845 phones? It seems that the Pocophone has some sort of heat pipes. I certainly don't want an SD845 that throttles way below an SD636 after gaming for 30 mins.

got my arc a few days back...apart from suffering from poor battery issues, I have noticed that when I play games on the arc, the top part around the camera starts heating up..
I observed it first when I was playing homerun battle with the charger plugged it..so I thought perhaps its because of playing while charging..
however, even after removing the charger and playing games, the heating continues..in fact the temp indicator on battery indicator shows temps of early to mid 30 C (86F) while playing games (I have not dared to let it go beyond tht)....while on idle it overs around early to mid 20C
is this normal?
my dell streak on the other hand rarely crosses 30C even on heavy gaming...
it's normal i'd say, mine does exactly the same. Infact most of my android handsets have done the same, must be due to the high processor power i guess.
When i have wi-fi off then the phone doesnt heat.
I think this happen cause of of many apps running in the background.
Sent from my LT15i using XDA Premium App
I never use the wi-fi on my handset apart from tethering, which is only occasionally but my handset heats up whilst playing games.
I think it's just down to the size of the handset. To fit everything into such a small body, all the components have to be very close together and that will impact how heat dissipates.
Think about laptops, they get noticeably warm when under heavy load in a way that desktop PCs tend not to, because there's more room in them for air to move and heat to dissipate - it's just the same but on a smaller scale, the differences in size of phones is obviously much smaller but so is the amount of heat being produced/power being used.
I would just like to say that the arc does not heat up very much, compared to an Atrix, that is. That phone regularly reaches up to 36c, and people have told me that going up to ~50 was NORMAL for it (eg using GPS navigation). The top portion also most likely holds the CPU and the rest of the components. I wouldn't worry about it too much..My arc is frequently around 30c during use. I think the battery life is quite good though
yup I thought so..its gotta do more with the size of the arc and what all it can do...and if you can go upto 50C then there is a long way to go.....
however, take for example my dell streak..its a 5 inch screen in a body which is 9.9mm thin...so a big phone and pretty thin but still it doesnt heat up too much...
on the other hand think about the Samsung galaxy s2...8.49 mm and a dual core processor...probably be a fireball after you play graphic intensive games on it for sometime..
Noticed it as well. My advice ?
Step 1. Buy a silicone gel casing.
Step 2. Place it around your phone.
Step 3. ???
Step 4. Profit.
Basically just ignore it - I'm pretty sure up to 40 celsius is alright, and the only reason why you notice it so much on Arc is because of how thin the device is. With summer coming though, I'd lay off gaming in direct sunlight
I once had quite a long session of angry birds; And after I quit, my temp was at 44゜C
Regardless of unhealthy temperature, it's still working up till now.
mine averages around 35. my 3G is always on and when on skype vc for a long time, it hits 43/44 too. but its due to the thinness of the handset.

It make not be incredibly thick but given the size of it's footprint, the components can probably be spaced out a bit more allowing the heat to dissipate more effectively.
My arc also heating up when I play dungen defender is really really hot especially the LCD screen...i feel that the tempreture is more than 60C ... will it damage the phone?
Jesus people, youre running a 1GHz CPU and a 3D graphics card flat out in a package not much bigger than a PCMCIA card, i think you can expect it to get a little warm.
When i think about the size of the heatsink+fan i had fitted to my first 1GHz desktop CPU to keep it from melting itself into a puddle of silicon, i'm amazed that modern phones manage to keep from spontaneously combusting.
^ what he said. remember, with higher processing power comes with higher heat discharge.
kinda offtopic but compared to the x10 where the cpu is under the battery, the heat would transfer to the battery causing it to overheat and reboot. i'm glad SE placed the cpu away from the battery.
it also seems like they've added a larger metallic plate (can be seen under the battery) in the Arc for improved heat dissipation.
+1. although bat temperature almost the same with my old phone, arc definitely feel err, cooler?
Hi guys,
My first time to post here, I know its normal for arc s to heat up when playing games. But is it also normal if on idle? it heats up to 38 degrees celcius. It concerns me because it drains my battery so much. Thanks!
all CPUs nowadays have a temperature threshold up to 70°C .. that means if the phone hits this temperature it will shutdown automatically, if this doesnt happen you dont have to worry and i think you will feel the difference between 40 and 70°C

Xperia Arc |Acronium 7.2| |DooMkernel v19|
Just got myself a Nexus 7 with 3G and Wifi about 3 weeks ago. Overall this is a great tablet and I love it. But playing games on this device will make it heats up quite abit on the back left bottom corner. I knw that every devices nowadays will heat up when playing games, surfing the web or even using mobile data.
And I was wondering, do any of you guys still play games on it when the device gets warm or in between warm or hot? I feel a lil disappointed because the Nexus 7's gaming experience and performance was good but the only downside is it gets warm in about 15 mins and and gets warmer at 30 mins of playing games ( high end games like Dead Trigger etc. ). And it's a pity that I cannot enjoy longer hours of gaming on this device ( which is 1 of the reasons I bought it ).
And also I wanted to ask, can anyone pls tell me how warm or hot is your device when playing games? What I mean was let's say I was playing a high end game and the temperature of the tablet is around 50 c. To me, I might feel that it's a little too hot but to others, they might feel that it's jus warm. Would greatly appreciate all of your answers and advises.
Thank you.
Well, to love something also means to accept it for what it is... So, show it some love... lol! Jokes aside...
It's perfectly normal for a device to heat up when it has to be at a higher clock speed to crunch high levels of data.
This happens to pc's all the time, we dont feel it cuz all the hardware is in a case being cooled by fans. Laptops too, try gaming with a macbook pro on your lap, i swear hard boiled eggs could come out by the end of it. lol! An ipad or even much inferior in performance tablets to the n7 do heat up. Nevertheless things are improving, nowadays processors are getting more power efficient which translates to less heat for the amout of processing power they have, which is much much more compared to the past. Mayb in the future we'll have something with the processing power of a mainframe but as cold as the n7 currently is, then mayb it can be downclocked and downvolted to levels where its as cold as a can of coke while retaining reasonable performance, but it wont happen today...
Yea, the n7 does get warm but if it really bothers you it can be solved if you use a thick sturdy case with it... I use it for that reason, also it seems to prevent screen lift in my case, not to mention protection against accidents =>
50°C isn't very hot, mine gets that hot during normal usage and it can go much higher.

LoL! Anyway, thank you so much for the reply and explaining. I'd never knew that the ipad would heat up too haha. Do you think I should underclock my device? Well, been trying to use a case but on the opposite side am afraid that the case would trap heat inside the device itself. But Im using it anyway lol... And I have to agree with you cases really do help alot in protection against accidents.

We all know why LG choose 808 over 810, now let's see the results of their choice:
Here we'll talk about the G4 operating temperature.
Try to indicate your ambient temperature, model, display brightness, app(s) used, your cpu utilization (I use cool Tool for it), and of course temperature (for that purpose I use Cpu Temp wich basically reads bms sensor of Cpu-z in overlay, and Cpu-z itself) ;
Remember to distinguish battery temperature from cpu sensors temperature and if using cpuz remember that temperatures are very sensitive to time so measure it only while performing the task wanted.
Keep it as scientific as possible
*I forgot to mention that CpuZ has an erroneous C to F conversion. So keep it in °C to be accurate
There is an intersting heat comparison HERE on Android Central to begin with
Good idea. Do note that CPU-Z seems to have a bug where it converts temperatures incorrectly from C into F, in the Thermal tab. From what I've seen, CPU-Z should be set to display in C, not F, if you want accurate readings.
To see the issue, check the temps, including in the Battery tab, then in the Thermal tab. For me, in C, the Thermal tab numbers seem reasonable, and the "battery" line in Thermal is close to the temp shown in the Battery tab. But change the units to F, and the Thermal tab suddenly reads the battery, and everything else, too-high by about 30F. The temperatures are not converting properly from C to F, the displayed C and F values are not equivalent. This conversion issue appears using CPU-Z on my last phone, as well.
So if posting CPU-Z temps from the Thermal tab, I'd suggest setting it to C, not F.
Thanks, I forgot to mention it, added
What's the point of this thread? This isn't a PC, it's not like we can do anything about the temps.

That is where you are wrong. It's called we can hard mod the phone for better temps.
Total newbie question, is the temperature you're feeling on the hand the one from the CPU, or the one from the battery, which is closer to the hand?

It should be the battery because I notice my phone getting warm pretty often and I have a widget for battery temperature which tends to go up to around 38 °C often. I didn't check CPU temperatures but I don't think the CPU is heating up too much.
82 F - sitting on the desk doing nothing but looking pretty. VZW, brightness at 0% and Auto.
All these freaking temperature problems will be resolved in a few months when the freezing winter arrive xdddddddddddddf

Lol, no, you can't.
At least LG choosing 808 instead of 810 due to hear issue was the right choice.
https://youtu.be/HltGLYZLySs
Take a look at a link above, SD810 might have upper hands during cooled state but that changes quickly throttling down below SD808 specs. SD810 potentials are pretty much obsolete and probably will never run on full more than 5 minutes.
SD808 is holding its speed even running hot. So I wouldn't really worry about hear part for this phone. But I'm with some users here. Few software updates will iron out some heating problems.

That's low for charging honestly if your referring to cpu temp. Most phone cpu temps stay around 25-35 idling and mid 40s when just doing simple scrolling and small tasks. 60-70c is fairly normal on heavier tasks and games. Kernels usually don't even start throttling until the cpu gets in the70-80c (generally most start shutting down cores at 80).
That being said, my G4 is one of the coolest running phones that I've messed around with. CPU-Z usually says that I'm in the low 40s even on some heavier tasks. I know that my Note 4 gets much warmer, much faster. Heavy web browsing for example will have my N4 in the upper 50s low 60s. The G4 stays pretty stable in the upper 40s low 50s. I'm happy they chose the processor that they did honestly. Stays pretty cool compared to the competition.
you can even mine cryptocurrency on this beast for hours on a normal (here normal) 27-30°C ambient temperature, and the battery gets to 44°C and the CPU gets into the 50s.
This phone has one of the BEST thermal management I've ever seen. I was a nexus 4 user, so you can see how much i was struggling.

At least LG choosing 808 instead of 810 due to hear issue was the right choice.
https://youtu.be/HltGLYZLySs
Take a look at a link above, SD810 might have upper hands during cooled state but that changes quickly throttling down below SD808 specs. SD810 potentials are pretty much obsolete and probably will never run on full more than 5 minutes.
SD808 is holding its speed even running hot. So I wouldn't really worry about hear part for this phone. But I'm with some users here. Few software updates will iron out some heating problems.

I don't pretend to be rude, but that information is outdated and inaccurate. I don't know how the other manufacturers are doing with the 810 to be honest, the Z3+ is sort of new and I've been checking the threads but there's too early to judge so far, it happens that I do have an HTC One M9 up to date, stock and unrooted and I've noticed several improvements through updates. Considering my daily usage I didn't feel this was matching with what I experience in real life, so I decided to redo the test on the video. I ran AnTuTu benchmark 64 bits version 4 times in a row, and left an average of a minute (sometimes less, once was a bit more cause I took the wrong screenshot) between tests. The attachments were uploaded in chronological order, you can also guide for the hour displayed from the device.
Now besides the video only runs 4 times, I did notice it was holding every couple of tests and then decreases, so I decided to run one more for the sake of pure testing and check throttling behavior, and surprisingly the fifth run gave me an increase on the score instead of lowering it further.
I didn't find a dedicated benchmark thread on the G4 forum, unless LG had improved a lot the 808, and based on the several benchmark results you'll find across the internet, including the ones in that video, looks like even throttling snapdragon 810 holds as an 808 in worst case scenario.
About heating problems, if I'm providing a success case scenario with a more troublesome chip like the 810 is, I'm completely sure the 808 will be fixed in time
phone gets crazy hot when running Periscope
it even shows that hot temp message / stops charging
try broadcasting for 5 mins
Intersting comparison between M9, S6, G4, Droid Turbo heat dissipation HERE
Periscope heats up the phone like crazy!
I too have had issues with the device getting very hot on the top half of the screen. Tried a couple of factory resets but it didn't help. Even reset one more time and kept it stock after a few hours same problem. Took it to the AT&T store and of course it was behaving fine. Luckily the rep knew me and accepted I knew what I was talking about. Swapping mine for one first thing this morning when their new shipment comes in. Will update if issue persists or not.
Wish I would have done it 3 days ago. Might have been snagged another battery and leather case lol.

I've been running benchmarks on this phone.
I've noticed a couple of things.
Thermal throttling on this phone starts at a very low threshold and is very aggressive.
Supposedly the maximum frequency of the large cluster is 2.45 GHz
At room temperature my phone never reaches that performance.
Here is a copy of the thermal-engine.conf, pulled from system/etc.
As soon as you start to benchmark the speed starts dropping:
At room temp I get Antutu ssores in the 130-150K range.
If the phone has been in a very cool room I get 160K numbers.
If I put it in a very cold environment for a few minutes I can get numbers in the 178K range.
Back to back runs plunge performance.
So it does not surprise me that the phone freezes at times.
Not happy that the phone throttles like this.
I have also found that if the phone gets to 44C then the throttling is so bad that a LG G4 or Samsung Galaxy S6 will outperform this phone.
So the thermal-engine.conf has this phone crippled.
This is speculative, but I wonder if overheating was the cause of the release delay. If so, perhaps this was the workaround they implemented to get the device out. That said, if throttling is the culprit then it could explain why my phone runs like an Evo3D much of the time. Generally before use, it's in my pocket, which is body temperature and the phone is always warm. Maybe even pocket-temp causes throttling?
Oh well, return initiated yesterday, awaiting response from CS - I just can't stand to take a chance a potentially crippled device. While the updated did increase the responsiveness of the screen a slight bit, I didn't see an overwhelming change that put this in the category of other devices running similar hardware. Back to the OP3...

So the device won't get really hot.
It won't even get that warm unless it's charging.
If you put it on a charger, it will be throttled after about a minute.
If I run Antutu and start out with the device sitting on a table in a cool room (too many conditions), I can get a score of about 167K.
If I sit it on a baggy of ice, I can get a score of about 177K but never unless the device is artificially chilled.
But if you run Antutu back to back or GeekBench and look at the temp, as soon as it hits 43C, you hit a wall.
The device won't heat up more than that but it's now running only slightly faster than a 6P and slower than a Pixel XL or Moto Z.
I don't want to pay $850 (yes that much if you include the extended warranty and tax) for a marginal device.
If I had root, I would have played with the thermal-engine.conf. It can't be right.
You go from full performance to half in a matter of 4 degrees C.
I have looked at other files for other devices and I've never seen anything that aggressive.
Even the 6P was not that bad.
I have an iPhone 6s (work) and no matter ho many times I run the test I always get about the same numbers.
I have my phone charging and I ran the test and I just got 115K. So on a charger the performance is 65% of max.
This is why I'm sending it back. Might as well be a LG G6.

Good to know, and thanks for the thorough diagnostic! Even with rooting and changing the throttle configs, I fear a voided warranty and bricked phone if it's a design flaw and not a software bug. It's just not worth it for me to wait and see when there are other new and shiny things just around the corner. *squirrel*

I'm pretty sure it's a mistake in the thermal-engine.conf.
I actually contacted them and submitted my information.
You don't throttle from 39-40C down to 50%
I've worked designing chips for better than 25 years.
If the 835 is more efficient than the 810, then there is no need for anything that aggressive.
Anyway, I asked for a RMA and they are sending a the boxes/envelopes.
No cases is a big deal for me also.
Since I'm already at $900 for the phone and camera (taxes and insurance). I might as well give the X a look.
Yeah, it costs more but if I'm already at $900 another couple of hundred isn't going to matter.
Unfortunately, I have to go back to my LG G3 since my 6P was sold and shipped last week.
Is there any way to disable the automatic over heat screen dimming? I'm tired of the screen dimming in the middle of my game.

Sorry but if it's overheating then it's a safety feature.
I'm sure you wouldn't prefer to be playing whilst you're phone is on fire.
I'm short, no it cannot be disabled, which I'm glad of as people would just point their finger at OnePlus.
*removes screen overheat dimming"
after 20 minutes of heavy gaming screen dies
*blames oneplus saying very bad phone bad quality etc.*
been there, seen that. to this day many indian users remove thermal configs on their oneplus/xiaomi devices and eventually ends up with dead batteries, ghosted screen, hell some just burn their phones (x3 nfc)
Cool the phone. A fan on it and/or a damp microfiber cloth. Avoid overheating the device.
It's possible for hysterious to cause the thermal protection to fail to adequately protect the device especially in direct sunlight.
The display's thousands of semiconductors are vulnerable to thermal damage, not just the chipsets.

Yep was thinking this too.
Slap a nice big heat sync on the back of the phone.
Problem is the battery is still going to take a massive hit every time anyway.. so you can't win really

Meh, yeah pretty much born to lose
The problem is the long game jerk off sessions on a micro laptop with very limited heat dissipation.
Limit to 5 or 10 minutes or use a gaming PC.

Turn down the brightness...
its not like i leave it dim when it automatically dims., i raise the brightness right away and do this until im done with my gaming session. Phone doesnt catch fire. Thanks for the thermal tip.

It's getting around a 100F ambient here, I use a damp microfiber cloth plus fan when charging and otherwise as needed.
I just watch the battery temp as the chipset runs cool (>120F) for browsing.

That's insane... Have you under locked or played about with CPU speeds? They don't always stick but may help.
I've seen a difference.
Are you using a case on your phone?
It'd be nice if a cooling vent was possible so we could point a solution at it, almost like a latch then have a pass through fan.
Or even plug in and stop using the lithium battery, that should eliminate a bunch of heat.

A stock N10+ snap running on Pie, brightness 30-40%, power setting: optimized, it's in a Zizo Bolt case. Optimized; no cloud storage, wifi, Google play Services, Playstore are normally disabled, and no social media apps. When I first got it it was a hot running power hog... a real menace.
At >95-98F if streaming vids* I need to cool it or give it a rest by browsing after 20-30 minutes. At 100F ambient that's getting near the 102F limit I try to stay below on the battery for best lifespan. That's what's limiting me, not so much the cpu core temp.
It's a clean running machine that's gorgeous, and gets good SOT. Samsung has given me zero incentive to upgrade it... so I bought a second new one about a year and a half ago.
*streaming vids uses almost twice the power as just surfing on the browser. Watching downloaded vids uses less as surfing.

It's 84F at 9AM, but should hit 104 today.
But it's a dry heat
Being inside is roughly 5° cooler by the time the ambient outside temperature peaks.
W Texas, is not Death Valley by a long shot.

It's already 91F here, the only reason it's not hotter yet was it's a bit overcast. That's burning off, no rain forecast for the next week, just heat.
I never use the power saving mode as it's a pain.
Oddly using peak cpu performance doesn't really add more speed than in the optimized mode.
Using max resolution you take about a 4-6% hit per hour. Even with 20/10 vision the difference is hard or near impossible to spot, mostly pointless to do.
Without a case the N10+ is hard to handle and would get destroyed. Not sure how much of a difference in heat dissipation no case makes as I never tested it. Not worth the risk.
The only bad thing with a case is spotting a failed swelling battery is hidden. Had that happen 2 years ago. Was very lucky the display wasn't damaged. Normally I take the case off every 2-3 months for cleaning as it attaches very little dust and dirt.
Always watch for changes in battery capacity and fast charging performance. If fast charging fails to engage or doesn't stay engaged within its normal temperature and charge % ranges it maybe a battery failure in progress. Batteries can fail at any time but is more likely to happen once a Li is degraded (80% or less of its original capacity).
This current Li has been hovering around 80-84% of it's original capacity for 6 months now. It's a little over 2 years old... I need to change it out soon. Lol, it's outlasted the OEM battery by over 6 months In all fairness though when I first got the phone it was a power hungry hog, took a few months to figure out how to tone it down. Another reason you want to always optimize a new Samsung; battery lifespan, not just for SOT/heat/performance.
Night and day difference.

Yea defo don't use qhd it's pointless..
Also wouldn't use power saver, I meant actually underclocking in Franco kernel
manager.
I knock them down a few notches, definitely helps.
Also with heat your phone will charge a tonne slower.. first step is 37c then 39 then 40 and so on...
Under 37c and you're getting the full 80 watts.
I think a case with some space In it would help with heat dissipation..
Android 12 also seemed to be much more efficient than 13, I've contemplated going back again and have done a few times.
Certainly shouldn't have to but needs must.

I'm still running on 9 and 10. Pie seems to run the best and is more functional. 10 has some nice tricks but has many dozens of new system apps for the UI. Oddly my disable list is nearly identical for both phones right now. That may change as I play with it more... but I really like Pie.
No plans to upgrade either. No malware on this phone (Pie) in over 3 years so it's relatively secure as configured/used.

The Snapdragon variants are notoriously hard to root. They also have a good vapor phase heatpipe on the SOC.
Not worth it as they run well now
