Edit:
From what I have gathered from those that have provided info.
Around 120*F is normal for heavy use, around 105-110* for medium use, 100-105* for light use. This is with cell data enabled, wifi lowers temps 5-10*, also temps are for extended use scenarios. (over 10-15 min)
Heavy use= 3D game or graphically intensive 2D game, streaming videos especially HD
Medium use= basic games web surfing sites with lots of images or some flash content
Light use= sending SMS, basic fooling with settings or other basic functions, streaming music with the screen off
I think we need to get a bit more scientific about testing this overheating issue out. I need help from a large group of people. I need those who think they have overheat issues and those who do not for the info to be useful.
First off... I believe these temps are just the battery, not the CPU. I think the CPU is running relatively cool as the rest of the phone does not heat up, or it seems what heat is felt is coming from the battery only.
This would explain why people claim that the extended battery does not have this issue. As batteries with higher mAh ratings are able to handle the higher power demands with less heat.
We need to do comparison tests using the same apps across tests and the same use times as well. Also no over or under-clocking and using the same CPU governor. (and between everyone participating where possible)
I have Minecraft and Sleepy Jack, they both produce similar temps after 15 minutes of play time. (around 117-120*F) I do not know if it gets any hotter with longer use because I rarely play longer than that at a time. I am at about the same temp after only 10 minutes so maybe that is the highest it gets.
I know for certain that enabling WiFi has a big impact on the temps. My fiance's phone would only get about 95*F, (according to the SetCPU widget) but when LTE is enabled it would get to 115*F. Mine hits 105* on WiFi.
I want to do at least two tests.
Lets use the following steps to test:
-For all testing the test time will be 15 minutes of play time.
-Lets all use Minecraft since there is a free version and I know the app causes the phone to work hard.
-No over or under-clocking
-On Demand governor
Test 1) Airplane mode enabled
Test 2) 3G enabled (not everyone lives in a LTE area, if you do, data from LTE enabled would be useful as well)
Now some optional tests. I did some rudimentary testing and there seemed to be an impact on temps.
Optional 3) Using interactive governor or Lag free governor
Optional 4) Use a different kernel... If you are on stock switch to ziggy's and vice versa. (this may be the most promising test as since switching to ziggy's I have had a few lockups where the old Android logo pops up on the screen and I need to do a battery pull to fix it. This happens to the fiance's device as well)
If you do these tests, please post the results, and what ROM and kernel you are using. I will keep track of the results and update as appropriate.
Lets see if we can find some consistent data and narrow this heat issue down.
Edit:
Running Ziggy's kernel I hit 108*F kept playing and shortly after the phone did the odd crash I mentioned.
Nice, had the same idea to do one of these over the weekend - you just beat me to it
I've done alot of research/ testing heat wise, and the pseudo-scientific conclusion that i've come to is that in a room temperature environment something like 75-85F idle & 110-115F netflix is normal for this gen of phones (Rezound, Galaxy Nexus, Galaxy S II, etc) - Give or take another 5F if you're using 4G. Seems like some devices are luckier than others & stay slightly cooler, but i'd gauge that they aren't the typical use case. IMO, (along side battery) data is a huge reason we've seen some of the face melting temperatures people have been reporting.
One thing I think would really help this thread is to set an easy to follow format for posting results. For example, here's a few tests I've done:
### Phone Info ###
ROM - Stock
Kernal - Stock
CPU Speed - Default (1.5)
Battery Type - Standard
Case - Generic TPU
## Test 1 ##
Charging - No
Data - 4G (4 bars)

This extended battery will get just as hot as the stock, just takes a little longer.
Edit-not quite as hot as the stock, but pretty toasty.
if it's the battery, then isn't the only parameter we need to test is current draw from the battery? no matter what radios/apps are enabled/disabled. It's bottom line is, the more we're drawing off the battery the hotter it's getting? I'd have to bring a pro in here on how Li-ion works in this form factor and why it gets hot, or what corners the battery manufacturer cut to make it possible!
The only time my battery gets hot is when I am in a weak signal area and the phone is searching for the 3G-4G signal. During daily use in a good signal area it never heats up.
My phone (and wife's also) heats up most notably during charging, especially when the battery is around 99% and going 100%. Usually the temp goes to ~ 45C (115F). In some rare cases, it was too hot to touch (dunno the exact temp). But some other times it would stay cool at all time.
Wife's first phone went into bootloop and her current phone is a new replacement. I kind of believe the overheating was the main cause of the bootloop problem.

It's more than just the battery. Also: feel free to post a test - the more data we get from everyone, the better.
One important variable missing: ambient temp.
I was just playing words with friends for ten minutes:
Ambient temp: 67, Screen brightness: 50%,
4g: ON
wifi: OFF
my temp went to 105F, it's NEVER gone to 105F when playing before... and I play it every evening. It was hooked to the USB charger at the time, and when I felt it getting so hot, I looked at battery monitor and my net charge was negative, so it was using more than it was charging off the usb...
maybe something in some of those apps triggers something that causes the temp to rise? a loop? something?

Good layout... and I think you are right about 115-120 degrees is normal for heavy use with apps that really stress the CPU or radio.

A pro huh... good thing I'm here.
Ok I'm not a "pro" as it were, but i know a thing or too.
Its not going to be simply the battery, but I think it is a big culprit, and most of these devices only provide battery temps, not CPU or internal temps, this limits our overall knowledge of what is going on internally. The battery getting hot causes the device to heat up as well so a bad battery that overheats can cause the device to overheat.
All batteries will convert some energy draw into heat. This is caused by the internal resistance of the battery. Li Ion batteries have fairly low internal resistance compared to other types, but battery design an affect power output handling. Pulling more power than the battery can handle or near its limit and you get more heat than normal. The heat to output ratio stops being proportional and becomes exponential. So that means the real kicker is the actual amp draw on the battery. How much power the battery can handle is related to both the capacity of the battery and the manufacturing process/ design of the battery construction. I bet the new devices are straining the battery more than the current design can handle. There are better battery manufacture processes for better power handling, but that increases the cost of the battery.
(BTW battery is a misnomer for these, they are cells, specifically one 3.7/8V Li Ion cell. The difference is that batteries are made up of 2 or more cells. This goes for AAA, AA, C and D cells as well. Car batteries for example are made of six 2V cells, 6V lantern batteries are made of four 1.5V cells and 9V batteries are six 1.5V cells)
This is one reason I want to do a test with airplane mode on. This helps lower the power draw and allows us to get a better overall device temp, this helps us know if there is an issue with the CPU getting excessively hot vs just the battery being stressed to hard.

I assumed most testing would be done at room temps of 68-72 degrees. If anyone tests in temps that are much higher or lower, then that would throw off the measurements.
I switched back to stock kernel, going to check for lockups and issues like I had before.

Charging always causes heat. You are forcing power into a small space.
Charging via USB should only get the battery a little warm to the touch. 95* or so at most.
Charging with AC should get it a few degrees higher. I would think over 100* is odd.
as you reach 100% is when the heat should spike to the max temps I mentioned, before that it should just be warmish.
I will check mine to see how it behaves, but all my R/C batteries behave that way.
Replacing the kernel with stock lowered my temps quite a bit. I was around 110-115 degrees after 30 minutes or so. This was with LTE enabled.
Nobody else have anything?
noticed most of my heating issues when 4g was on (even when idling on 4g). Leaving in wifi and 3g keep the stock battery cool...on the extended I never really notice the heat, even on 4g.
I realize that you're trying to keep things as similar as possible, but I had an issue today listening to the broncos game in the NFL app while charging. It got so hot it boot looped. After getting it back up and running I started monitoring battery temps and even with the screen off and just listening to the game, it would get extremely hot. Btw, I have 4G 4 bars. A couple of times I ran to the freezer and put the phone in it for a couple minutes to cool it down as the temps got above 117°F.
From here, I thought it might be the CPU, so I set the maximum setting to 384 in antutu and then let the phone sit there with the screen off just as before listening to the game and still charging. Same thing, phone got extremely hot, 115°F. Although, what I find strange, is I can watch Netflix while charging and even tho it gets warm, it never gets above 115°F and never goes into the boot loop issue. Same exact location, charger, ambient temps, signal, the works. So I'm wondering if an app is just poorly written and causes some sort of excessive use of the radio.
On another note, I had a rezound battery in my thunderbolt and never had any issues what so ever with heat.

What temperatures are you people expecting to see just out of curiousity? I mean if we run 3d intensive apps, videos, extreme web browsing we're going to see high temps since we are stressing the devices. We do have to remember these are compact devices and they are limited to what type of heatsinks/cooling they can add. From the multiple posts form this thread and others like it, we can see the majority of our devices run at same temps while under load. If it hasn't already been done maybe we should contact HTC and see what they say? Just a thought.

I am trying to find the norms and what is too hot.
I am thinking 115 is normal for heavy use. But we need to be sure, if someone says they only hit 100 under similar conditions as someone that hits 120. it may be that 120 is a problem temp and that 100 is normal. It may also be that the person only hitting 100 is just lucky.

Go play an app that is heavy in 3D, lets see what temps you get. If you go much over 120 it may be an issue.
Running Gun Bros for about 20 minutes gets me up to about 105°F. Right now after the phone had been sitting for 5ish hours doing nothing its at 98°F.

I think it is Ziggy's kernel I have never got 125f when tethering for 30min or playing GTA for 30 min. I am going to try another kernel.
I have a 16g black one from Google Play. and luckily it has no light bleed, minimal give on the back but the thing just get HOT even when I am using tasks like watching video or reading Chrome like now. I monitor the Cpu temp and it is around 40 > 50C when watching video surfing the web etc. However, when I am playing 3D games and stuff it get to about 60 > 75C. I dont know if it is normal or not and is this just a software or hardware issue because it get really hot on the top near the camera and both the screen and the metal rim get hot and burn my hands. I am considering RMA it if is cant be fix through a software update though. So is can it be fix through further update or rooting and new custom rom help ? And is a case gonna help reducing the heat to my hands ?
Also if I wait for the next batch can I wait and exchange for a better one then ?

Guys, can anyone help ?
This is normal. Any processor heats up with heavy gaming. The nexus 5 (snapdragon 800) can break the 70C mark in some cases. The nexus 7 (2012 with tegra) heats to 60C before throttling. The nexus 9 does try to dissepate the heat as quick as possible (lots of copper) and feels warmer.
Samsung devices are even worse, as they start throtteling even later.
The tegra k1 is a beast of a mobile processor (gpu and cpu).

Basically, this.
Hell, my N5 actually reboots during antutu due to thermal heat and heats up a lot during gaming.
Also, the reason it heats up when watching a video, do not forget a video has to be decoded to be displayed on the screen. Hardware decoding is less intensive but some still rely on software decoding wich will heat up and cpu in a matter of minutes. So even something as simple as watching a video can be CPU intensive depending on the decoder.
As for chrome, haven't had my N9 heat up during chrome sessions. Weird
Actually, the Nexus 9 manages as only Android device in my collection to stay completely cool in netflix HD streaming. 10% battery usage after 90 minutes. Compared to the other devices that use up at least 40% of battery during the same time.
One drawback is the 4:3 screen, which still makes my Note 10.1 beter for netflix (or movie viewing in general)... But the Nexus 9 is the only tablet I even consider using in portrait.
Same problem here, especially with Chrome. I've rooted my device, I don't know if that could have something to do with the heating...
Chrome Beta seems to have really helped with the heat issue on mine. I still get a lot of heat with gaming but that seems to be it.
The n9 was the first device I've ever had that heated up on me while browsing in chrome. This is NOT normal. I RMA'd it and picked up a shield instead... I don't know how these devices passed QA with all the issues they're having.
My personal opinion, is lollipop isn't quite ready and many apps aren't either. I'm waiting for all to be updated. The heating problem will, I'm sure, be taken care of.

I noticed the other night a considerable warming by the camera area and all I was doing was browsing the Internet. So as I was using Chrome I stopped, and browsed with FireFox, the tablet cooled completely down. Even watching YouTube it was barely warm.
I think something is wrong with Chrome and it's causing a loop somewhere in the code ramping up the CPU causing it to use a lot of power and that equals waste heat.
Playing games also has the same effect, it ramps up the CPU. The CPU is probably rated to continue working up to quite a high temperature before it needs to slow itself down to allow to cool, but when that heat causes the case to become very hot, it should back off the speed and so keep itself cool a long time before it reaches any of it's own temperature maximums, the trouble is keeping the case cool means the CPU can't maintain high performance for very long, so what's the point of a fast CPU.
Really tablets are not the best designed devices for 3D type game playing, or anything really that needs to use a lot of CPU power over and above the occasional burst.
I wouldn't be surprised once all the benchmarks have been done and published, if a software updated doesn't fix the heat problem by throttling the CPU quicker, and running it with realistic performance characteristics that being sandwiched in a very thing plastic case with no vents or active cooling requires.

I second the chrome beta helping. I disabled regular chrome in app manager and installed the chrome beta and have had a significant boost in battery life and decrease in heat while browsing.

Do you still notice any warmth using Chrome Beta? Or is it relatively cool? I have tried both Chrome Beta and Dolphin, and I am still noticing a good amount of heat. It's actually cooler watching Netflix than it is doing any sort of browsing whatsoever.

Saturday when I switched to the Chrome beta for the first time the heat was the same as before. Yesterday and today it has been noticeably cooler. I'd say the tablet gets just warm enough to notice a difference from it's ambient temperature when using chrome beta. I've gotten slightly better battery life but i'm still only hitting 4 hours screen on time when I hit 15% battery which is about a 1 hour increase from before using chrome beta.
I think chrome is still in need of major optimization because as you said when I use youtube or netflix I get much better thermal and battery performance. I did notice today that chrome seems to be performing extremely well on page loads and interactivity with javascript elements etc. I threw as many complicated sites as I could at it and made sure to go to sites I that hadn't been cached before on the tablet and it was super fast. It actually impressed me with it's performance which I wasn't expecting. Now it just needs to get more battery efficient and it will be perfect.

Thanks for the details. It's a shame that browsing is so poorly optimized. That's my main purpose for a tablet. I've just been on Dolphin the last hour and yep, heat is still pretty strong and my battery has gone down quite a bit. But before that, I was running Netflix for several hours just to test, and was up to about 5 hrs SOT. But I typically don't watch much Netflix, so that doesn't reflect real-world usage for me at all.
Yeah it's a little disappointing but the improvement I saw from chrome release and chrome beta is promising. My browsing experience today aside from heat and battery issues really made me like this device. The performance really blew me away. It felt more responsive than my i7 desktop.

I too find myself getting attached, despite these issues. It's a really smooth tablet experience :good:
I have the nexus 9 since December and I absolutely love it . It's an amazing piece of technology . Recently I started to notice that the battery was draining too fast , barely 4 hours of screen time. When in the beginning it was 5:30 hours. For example, when I left the tablet an all afternoon without touching it, it would only spend 1% which is pretty good, now is 3% which is a big difference. Overall it's just spending battery way too fast . I don't have those battery sucking apps and I only play for about 20 min or less. I have everything stock and non- rooted.
Anyone else experiencing this?
I can't say for certain that I'm experiencing the same thing. Perhaps it's because I keep my brightness pretty low all the time (I'm used it like that) and I'm definitely getting over 4 1/2 to 5 hours on mix usage. I pretty much use my tablet as a web-browser-note-taking-google-plus-using-facebook machine. How much available RAM do you typically have on idle (minus the settings app)? I typically have over 1GB of free RAM.
(also to note: my nexus 9 is stock and non-root like yours)
Hi guys, this is something that keeps me up at night. The recent software update was supposed to make performance of the Moto Z better, and in actual daily usage I find nothing to complain about, but when it comes to benchmarks it's a whole different story, I have the uk version by the way. To be frank, I used to get about 129 000 in antutu, which is pretty low to start with, and now it's down to 126 000, geekbench is lower than you would expect from this phone too, at about 1350 single core and 3810 multicore. So basically I started this thread as a place where we could share our benchmark results and discuss them, because I have a feeling I just got an unlucky unit, because it also gets real hot real fast (up to 60 degrees celcium), and I can't make it last for more that 4 hours of screen on time, and I'm really not a heavy user. I just feel strange about this phone, because I love everything else about it, and it’s good that I do, because resale value on these things is beyond awful, tried to sell it for 500 bucks for months with no success.
Benchmarks mean abso-farking-lutly nothing. If they are keeping you up any night, you have a mental issue. I suggest you see a shrink.

Well, there is no reason to be so toxic my friend, my main concern is that I may be the only one here with such a low score, and since the score got even lower after some time that could mean I may have a defective device, and that would be a real problem to keep me up at night.
I don't think there's a problem with your unit, 4 hours screen on time sounds normal without the battery mod on. That drop in benchmark score isn't very significant unless it continues to drop dramatically. I have the UK model too, and it is underclocked by default to 1.8GHz. You could try the Turbo Z kernel to improve it
Also mine gets really hot fast when using Daydream VR or anything intensive but 60 °C isn't dangerous for the SD820. (You could check battery use in settings incase something is keeping your phone awake.)
Geekbench 4:
Single core 1369
Multi core 3779
Seems benchmarks are pretty similar. I'm on rooted Android N but stock kernel so same as yours.

Well, there is no reason to be so toxic my friend, my main concern is that I may be the only one here with such a low score, and since the score got even lower after some time that could mean I may have a defective device, and that would be a real problem to keep me up at night.

The only benchmark that matters is the one between your ears. And according to you, it passed.
in actual daily usage I find nothing to complain about

All others are a waste of time.

I don't think there's a problem with your unit, 4 hours screen on time sounds normal without the battery mod on. That drop in benchmark score isn't very significant unless it continues to drop dramatically. I have the UK model too, and it is underclocked by default to 1.8GHz.

Thank you for your comforting and friendly reply, in battery settings Android OS, Android system, and phone idle are on top when I'm not using the phone actively, I've had laughable results sometimes, like yesterday I had 30 percent battery left with only about an hour of screen on time, again no gaming involved, but this usually happens when I'm moving around, if I stay at home and nothing happens to the phone it usually won't drain battery like that. I think the reason the phone gets hot easily is obviously because of how thin it is, for example, when I keep it in the pocket it's just as hot as my body tempreture, since it just absorbs heat that easily, but has a hard time getting rid of it.

You're welcome. If you click on the graph you can see the awake time too, lately something has been keeping mine awake and draining the battery too. Not sure what it is yet, but if yours is getting really bad screen on time it could be similar. Likely an app running in the background keeping the phone awake which would heat it up more and drain the battery. There are wake lock detection apps that claim to be able to tell you which is causing this.
As you can see it's awake for long periods of time when the screen is off, and it really shouldn't be. Hope this helps :good:
Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Xiaomi Redmi Note 4 stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!
I'm no gamer, but I didn't faced any heating issues so far.
Maybe I can't speak about heat as I used to use a galaxy S4 exynos (it's a portable cooker in case you don't know, easily reaching 96°c when just browsing on battery), this never heated, the temperature is about 45°c and it never felt uncomfortable hot, actually it never felt hot even in high external temperatures, I don't game on my phone, also I don't do highly demanding tasks, but I guess this phone can stand very well against whatever demanding task you want..
Ya very less heating in rn4
This phone is cool as... Hm, how to explain this.
Imagine hell.
Now imagine it has frozen.
That's the heat level of RN4. Snapdragon 625 does it job.
My phones been fine, up until this last few weeks...
Where I can't hold a charge for more than half a day... And even running phone a USB socket on the computer, the phone still discharges faster than it can charge. Battery getting hot too... I've tried looking to a culprit app that might be churning the cpu. But even process Explorer isn't showing high cpu use from any given app.
The battery app which shows what apps drain most doesn't seem to show it either.
Really worried and nearly giving up. Might do my first factory reset in the 2 years I had this phone. Maybe time to root it and install another rom, Any suggestions?

Just trying to comfort you - you are not alone!
First, it's my secondary phone and I use it only when I travel. So not sure since when that happens. Maybe since a week or so.
Now I can lose like 30% in one hour, and the phone gets really hot. I used the last 2 days. Example, this morning it had 100% after overnight charging. I went for breakfast and lost 30% in one hour (rarely use the phone when I was out).
Then I charge a little in the car, phone went went from 58% to 64%. Then for no reason battery life was normal again and by the end of today I had about 20% - and then suddenly withing 20 Minutes it went dark.
I have the phone for about 2 years, this problem is very new.
What I try right now after reading stuff on the internet, so it must be true:
Remove all updates to Google Duo (this app can't be removed) and disable the Auto-Update for it in the PlayStore. Lets see..... (it's an app I never used, had to lookup what it actually is). Did that 15 Minutes ago and phone is already much cooler.
Ok uninstalled updates to duo and blocked auto update in playstore... ill see if that helps... Thanks for the tip
I must admit though, this had made me consider getting a new phone... but I dont really want to the phones good (when its working right) does all i need i to do.... Sure newer phones are a tad flashier but not enough to make me jump to get a new one.
Wow, That appears to have worked..... I mean its not really long enough yet to tell but it does appear to have stopped the fast draining and heat... At least for the first few hours....
Thanks
So if it really is duo causing this battery drain, why do no battery analysers seem to show that?
And is it doing it to all smart phone with duo and I guess it's latest patch installed?
Has duo been spying on us? Has it been running the camera and watching us while we sat on the loo, which I'm soooooo currently not doing..........
Thanks! The recent heat issue after an update had me thinking i need a new phone. I really like this phone, its lasted me by far the longest, and best run times of all I have ever had. I was worried about fire, did a full factory reset with no installed apps, but heat was still there. I removed updates to Google Duo, and stopped any future updates as listed above, and its running cool and clean again.
Once again thanks for this post!
Yep can confirm now after a few days... no heat no fast draining... Google Duo was the culprit... is it a but that just affected mediatek cpus? Or do all android phones suffer this bug? is anyones heads rolling at google for this farce?
ITs fine and good...... no options.
While charging and playing games or using heavy data apps.... it wont get heated like expected when connected to electricity.
When on power banks it works otherwise , gets charged and increase in temperature.
One of the best thermal performance I have seen on a smartphone, thanks to the Snapdragon 625 chipset powering the phone. It had no competition back when it was launched.
Using this phone for gaming almost baked my hand
