Overheating!!!!

Guys, I don't know but Note gets heated up a lot from the camera Side.. the battery remains cool though.. what is this?. can It be stopped. I guess your notes must have been suffering from this? any solution?

Heating ....how much...generally while charging it gets heated up. Try some google aps any of those battery savers...they have an option to show the temperature. Also are you always of Wifi...if so your screen is sure to generate heat, which is normal.
Above all if it gets heated if you are not charging and not on Wifi does it cool down ? Considering your battery charge is above 70%.

The phone heats up near the camera because that is where the CPU is located.
Running 3D games and other apps that require the phone to run at high CPU frequencies will heat up your phone.
If you want to avoid heat completely, then you need to look into Under Clocking and Under Volting.
It's simpler with a rooted phone and a tool like Rom Toolbox Pro.
Under Clocking is where you limit the max CPU frequency the phone can use.
By default the Note is limited to 1400MHz, set the maximum frequency to a lower level, e.g. 1000MHz.
Under Volting is where you limit the current the CPU draws from the battery at certain frequencies.
Make sure you do some serious reading on XDA before you Under Volt, supplying too little current to the CPU will make the phone unstable and potentially corrupt data.
The advantages of Under Clocking and Under Volting are reduced heat and better battery life.
The disadvantages are potentially poorer performance in 3D games and other intense apps, and instability if Under Volted too far.
Hope this helps explain what you are experiencing and some potential mitigation.

Benchmark is bad on RR

I am running RR and am getting under 40k with antutu benchmark
i am wondering why it is so low and if someone can help me.
i am running xposed with the following modules
amplify - not blocking anything though yet
app settings - used for a couple apps that need 640 dpi to operate since i am running at 480 dpi
blacklist
boot manager
google offline voice
greenify
iFont
unbelovedhosts
xinstaller
xprivacy - not blocking anything with it yet
youtube adaway
is there any apps that would cause such a low performance. i tried installing the kernel by @BayButcher and modifying it to his battery suggestions and i am about to try his performance setup for his kernel to see if that does anything. but i was getting near 50k with stock so i figure i should be better with CM12.1 or RR.

In thermal settings, you will have to set the temperature higher. Intellithermal aggressively throttles the CPU. I set it for 65 degrees for just "normal" operations, because it seems to start throttling 10 degrees sooner than what you set.
So for a benchmark that makes you feel better, set the degree limit even higher. How high is however high you are willing to risk... Also, before you take the benchmark tests, stick the phone in the freezer with a ziplock bag for a few minutes to let it really cool down. Then start the test, put it back in the freezer while the test is running. The phone will run faster longer while cool, and won't throttle the CPU.
I mean, benchmarks are for bragging rights, yes?
When you finish the benchmarks test, then put the degree limit back down to like 65 degrees for everyday use.
______
50,000 -- here's Antutu results at 65 degrees throttling and freezer trick. I could get higher if I set my thermal setting even higher -- which would be safe temporarily as long as I chilled the phone first IN the freezer and kept it there during testing.

I agree benchmarks are for bragging, but they are still a benchmark. if stock out of the box i can get a 48-49k benchmark and i do some mods and can get a 55k benchmark that is for bragging. but if it drops to 40k something is broke. . I am going to try the increased temperature and run another test. the performance setup only got me to 41k.
i am really confused now. i reinstalled computerfreeks ROM which before bootloader unlock gave me 50k and now it gave me 35k. i am going back to RR because I like it more but need to find out what caused performance issues.

My main point is while the custom ROM may give you increased performance and options, the default kernel thermal throttling points (for frequency as well as for core -- two separate settings) may be sabotaging benchmark tests.
I increased frequency point to 65 degrees, because that REALLY means 55 degrees, for some reason.
I didn't even touch the "core" thermal setting...
And my 50,000 result was on stock 640 dpi.

Cm12 is the same way. Low benchmark. I'm saying with exposed and stock

Yeah, but you obtained those results by tweaking the phone and subjecting it to non-real world conditions. I can get 52K on the stock rom by doing absolutely nothing and having a bunch of xposed modules active, and I think that's the issue that the OP is concerned about. The relationship between benchmark scores and real world performance is debatable, but I think he has a valid point.

The caused of the performance issues is simple heat vs battery level.
Has the device get hot it get low score because more throttle down, has the battery gets low same ting there is a setting to lock the clock under a frequency if the battery get too low, it starts only at 20%.
very simple table:
Code:
thresholds 80 85 90
thresholds_clr 79 84 89
actions cpu cpu cpu
action_info 2265600 1958400 1728000
this is editable this is in the file
system/etc/thermal-engine-quark.conf
I never try to edit it but you can.
But in my test I find that there is more then this file make the performance get low, and for me is just the battery as it get low the performance get too, but the battery is only responsible for some very little % of this the heat is 90 to 95% responsible.
So be aware that you problem is more heat you heat your device installing ROM make and restore backup don't give time to the device cools down and test.
No matter the ROM you try that will be the result, unless you can set the temp threshold higher like in a custom Kernel.

I am willing to buy into the heat issue since i am changing between ROMS and such so i got a few things against me
1) chargin phone
2) restoring different ROM
3) not giving adequate time to cool
i am going to let eveything settle a little with RR and retest. i am using your kernel and used your performance recomendations. i am not a gamer i just do not like clicking a button and waiting. or wa5tching me type faster than the phone can output to a field

Yes exactly. i did nothing between test a and test b except unlock bootloader and install RR, CM12.1. and yet i got a huge performance drop. but same issue was with the computerfreek version which is like stock. so i am thinking it has to do with something else not playing friendly.
i would assume if with stock out the box i could pull 50k then with RR and a kernel boost i should be able to pull 52k.

Tweaking the phone? Mostly all I did was change the CUSTOM kernel throttling conditions. When you root your phone, from that point on you are TWEAKING your phone. Give me a break.
Yeah, I also cooled the phone, so that is non-real world conditions, but changing the quite arbitrary throttling point is quite logical when it's been PROVEN that throttling point affects performance and actually starts throttling even sooner!

To me dont make any difference, the better Gorvernor works well with my Moto maxx are Interactive_pro.
To getter better performance of my phone, i need change Thermal Frequency Throttle to 80º C, most custom roms use Intellithermal method, and they are very sensivity to temperature.
If you choose 80º C, they will reach in max 70º to begin the throttle the processor.
Stock Custom Roms are 60ºC in Thermal Frequency Throttle, i change to 80ºC and my phone are very fast now.

So, on your custom ROM kernel, change your governor, change your throttle points.

OK i am satisfied here. i unplugged the phone and benchmarked at 50.7k. apparently charging the phone cripples its productivity. i did not think it would cripple it that bad. and if this is a known thing i apologize for the posting.
i can now go back to enjoying the awesome RR and tweaking it.

Yeah, okay, so all you did was change some throttling conditions. But you know what I had to do in order to get a higher benchmark than the one you got? Nothing. At room temperature. That's a problem. One of the main purposes of unlocking one's phone is increasing performance, not reducing it.
If the problem is simply an incorrectly set throttle point, all you should have to do to get 52K at room temperature is change the throttle point high enough, right? No cooling required. So let's see that. If you can get 52K without melting your phone in a normal usage environment, then good. No worries. Mine didn't even get hot during the benchmark, so you should be able to easily exceed my 52K score. If not, there is an issue that I think should be addressed.

Charging = heat generation = throttling, so yes, that would do it. I'm still curious to see if CM and this custom kernel can break 52K though. I'm waiting for CM13 before I make the switch, but I might reconsider if I have to sacrifice some performance. The technical power of this phone was half the reason I bought it.

Stock cm12.1 benched 48,000 screen on.
Screen off it was 43,000.
I'm happy with it. I also think the battery life is mildly better.

After you flash it there is nothing saying you need to change anything.
I would imagine he has the presets at what he thinks is best.

Just FYI, I'm running computerfreek's latest unlocked ROM with xposed and about 10 modules. No changes to thermal setting (don't know the default for this ROM either), and just have it sitting on the desk. I'm also, getting unbelievable battery life with servicely, amplify.

the writer of the kernel has said it needs some adjustments since he does not turn them on by default. but he gives 2 setups, 1 for battery and 1 for performance on post #2. i just set it up as per post #2 until i understand more what is going on with the kernel.

Which Hardware Revision do you have?

Hi,
After reading in another thread that there are different Hardware Revs i took another look at my Box and found out that's true.
{

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

So how many different version are there? Someone said he had Rev 3.
How is the distribution? Timebased? and How many of each...
And most important, what's the difference.... anyone knows anything?
So, as you can see in the Picture above, i got the H8216 in Rev 2.
What do you have?

I don't know about differences but I have revision 3.

H8266 revision 3 here.
I'm not sure if I am not noticing it, but I do not experience touch screen sensitivity issues when I play games or maybe they are minimal. Granted I play rhythm games and mobile rpgs, not fps or fighting games so maybe its just me.

H8296 Rev 2

H8266 Rev 3

This thread is pointless if revisions are not linked with specific comparisons in behaviour.

Revision 1, and I'm having massive heat issues. Recording videos, especially with SteadyShot, HDR and 4K activated is stopped after 7 to 10 minutes usually, because the phone got too hot. I'd like to know if later revisions fix these issues.

Does Revision 3 fix the hardware issues?

I have Deep Green H8266 (Rev 3).
I don't experience too much heating issue and don't experience touch sensitivity issue either. Battery life is great and can be really amazing, a lot of time (reaching the point where I'm struggling to drain the phone's battery at night, just because I want to charge the phone at 15%). It is also lightning fast, superb gaming performance, and has great multitasking performance, too.

H8266 Rev 4 here, just bought it a couple of weeks ago after frying my Z5p, I had no intention on getting this phone, was going to wait til the end of the year to see what Sony will offer but necessity obliged ?
Absolutely zero issues, no heat or screen sensitivity as other mentioned, this thing stays cool and is lighting fast, battery life is insane, crossed a few times 10+ hours of SOT...just waiting tight for a drm fix to root and xposed (whenever that is)
The only thing that bugs me is the esthetic of the phone, not a fan of the back side at all (finger print sensor works pretty damn well though, still prefer a side placing)

Impossible physically. The battery is not big enough to sustain that long of a SOT no matter how efficient you claim to be. unless sony changed the battery capacity in their latest revision, conning people who got earlier revisions.

I haven't had any of the issues reported, the phone never seems to get hot either but I don't play games very much and for the time that I just got slightly warm. I agree with the battery life, it's really amazing compared to everything else I've ever owned.

This pic below is not from my phone, it's from the xz2 thread on Esato, so you can see that I'm not the only one either...I didn't take a screen shot of mine when I crossed 10+ hours (I will next time)... I said that passed it a few times, mostly range in the ≈9+ hours...
I don't game, few accounts with push notifications and an email client with 3 imap notifications (so those run in the background constantly)
This one below is from my phone...I'm at 1.5 hours of SOT with a 12% down from full charge...you can extrapolate the end results ?

Lol.
The Battery inside the XZ2 has:
Min: 3060mAh 11.6Wh
Typ: 3180mAh 12.3Wh
So i've measured the powerdraw for Screen+Phone Idle/flightmode:
Minimum Brightness uses 0.49W
Maximum uses 1.83W
Screen Off uses 0.24W
Doing the Math even at full brightness if you use your phone as E-Book reader you could reach 6h 45min At Minimum even over 25h!
So yes, it is very well possible.

Hm. Before the XZ2 I've had a Xiaomi Mi 6, which impressed me more in terms of battery. Smaller screen, bigger battery (and much slimmer phone).
And IMHO it's not better, perhaps worse than my LG V20. I did take a lot of photos, which does seem to drain the battery badly.
I really wonder what they have done through the revisions. It seems clear to me now that revision 1 had some serious flaws (or maybe my unit is defective), especially in terms of cooling.

Rev 2 i have
Wat is exactly the point of this... More info please and can you explain us what Rev 1, 2 and so on is and what it mean ?

No one except for Sony probably knows. But it is interesting to see, which revisions made it to the market and which didn't. And if people report on issues with their phone, we can at least figure out a bit what was fixed. Also now we know there are 4 revisions so far. Mine is revision 1 and says demo only, not for sale. So maybe it is also possible to find out when these phones were released.

Red Magic Vs OnePlus 5T speed test

Hello guys, I've got the OnePlus 5T and I was looking to upgrade to the Red Magic eventually but after watching that speed test video https://youtu.be/okGb8lqg8fA I don't see the RM being any faster and the active cooling seems to be a gimmick of some sort as it runs hotter than the OnePlus 5T as shown in that video. I know the firmware is not final but I seriously doubt they'll do any miracles especially in the stock version...but in the same time I'm scared of getting the Chinese version because it probably won't support Play Store and so on. What do you guys think, should I keep the OP5T?

Well hopefully we'll see more optimization before long on the RM. I haven't had any heat issues, and it has seemed cooler than most. Even when I was running an app to intentionally drain the battery by activating everything it didn't get that hot.
Overall for general performance, you won't see much performance difference between the two. They use a lot of the same components. Theoretically you should see some performance gains with game boost on because it locks the last four cores to their max frequency. No operations used trying to dynamically adjust. Really depends on if the app would even benefit from the frequency boost though.

I guess if the game button triggers the full potential of the CPUs that's why it heats up more than the OP5T which never runs on 100% but somehow manages pretty much the same frame rates. You must be right about whether an app can actually utilise the full potential or not.

Old post revived. But did you see the stress test of antutu in that video ? Nubia tries to stay almost to 100% all the time. That's how a gaming aka performance phone should be.

I know Exynos 9810 has heat/battery problem so understand why Samsung made a better cooling system on Note9. But if this is true I skip Note9 too. Heat problem also make battery life shorter than expected

I am using NOTE 9, no big heating issues so far. Even with faster charging, it stays cooler than iphone 8 plus which i own too.

Good news, good confirmation. Could you test some heavy games or some 3D benchmark to confirm heating free?

I saw some Youtube clips about N9 and want more people confirm about this problem: hot and hotter than S9+
1. About 46° C @4:20 this video:

2. Compare to S9+, Note9 also hotter @2:25 this video

Here's a good read on the Snapdragon 845 test device:
https://www.xda-developers.com/qualcomm-snapdragon-845-hands-on-benchmarks-first-impressions/
An excerpt regarding the temperature when pushed to the limits:
..................We also ran the Manhattan ES 3.1 Endurance / Battery Life test on the Snapdragon 845, a 30-minute test that pushes the thermal envelope of whatever device it’s run on (with the Snapdragon 845 in particular, we saw an absurd peak surface temperature of 47°C | 117°F), and despite the unit becoming unbearably hot, the framerate only dropped around 16%, and stabilized higher near the end of the test. This is certainly not bad considering that we normally make sure to start this test at a cool 28°C | 82.4°F, a luxury we couldn’t afford in a (literally) heated benchmarking session. We’ve provided some graphs comparing the throttling across the 821 and 835, but keep in mind those results were obtained in much more controlled testing environments — I wouldn’t draw strong conclusions from these specific results............................

Seem SD845 also has this problem. Seem Samsung just made bigger heatpipe on PR purpose. Exynos Soc has big problem on heating/voltage/battery effeciency problem ( Anandtech article )
Edit : your link not Note9 article, so we need more test/review

Yeah, more details might show up slowly as few reviewers seem to be talking about the "heating". :good:

Hello Guys. Here i did some tests. I did ANTUTU, STRESS TEST and 3D MARK
It says "51 Celcius" there but definetely not 51 degrees, doesnt feel 51 degrees. It then changed to 46 celcius immidiately. In stress test, it heats. Every phone heats.

Tks for your test. Seem better than expected. 51°C is on die temp which is normal with every Soc/CPU.
Battery temp not so high during the test and drop fast. How about your enviroment temp? With fan/AC or not?

I did the test outside at about 30 celcius. I live in Turkey.

Seems normal on this video

This is not a clear test. It cannot be about 37°C with high Soc usage game

y'all do realize that no cooling system is going to keep a device from getting hot right? All it does is spread the heat area in hopes of keeping the actual chip from overheating by increasing the radiative/coolable surface area.. You put a freaking supercomputer in your pocket. It's GOING TO GET HOT WHEN YOU PUSH IT!

I have been reading around and it seems that the exynos version of the S9+ is plagued with heating problems that yield 20% less battery life then the snapdragon. There are also some tests that show exynos s8+ outlastning the exynos s9+ under same use conditions.
Interested to know if the exynos note9 has the same issue.
Main reasons I am looking to upgrade note8 to note9 is bigger battery (and storage as i use 2 sims). I would be very disappointed if due to extra heat from the 9810 the note 9 would yield similar battery life on the note8.
