Hello, I have been using HTC U 11 for a couple of days now. I find it really odd that the temperature is kinda little high at all times. here are my observations.
before I start im from chennai and the avg temperate here ranges from 28 to 35 on a normal day.
I first noticed heating when I was recording a FHD video at 60FPS for more than 3 min. The camera stopped taking video due to overheat. The phone was uncomfortably hot. But then I realized maybe its because I was riding as pillion in motorcycle while recording and it was 1 PM in the afternoon with Sun burning your eyes. So I thought maybe its because of that.
then taking any 4K, hyperlapse videos increased temperature. So i used CPU temp to analyze the temperature(with back case removed) I was in a AC Hall with room temperature of around 26 degrees C and the starting temperature was 36 degrees C in my phone. Then,
I took two 4K videos 1 and 2 minutes each and the temperature went from 36 to 47 and once the video is finished it settled back to 41. the CPU was at 1900 MHz while recording and throttled down to 300Mhz once its done.
then I ran 3D Mark tests. it gave me a score of some 2.7K with an average FPS of 25 but while performing this test my CPU went to a whooping 53 degrees C and settled back to 45 degree C once its done. Normal Phone operations like FB, reddit, discord etc gives me around 36 37C which still, i feel is too much and despite being a glass body I have never felt any form of chillness even after hours of being in AC room it was always pleasantly warm when normal use to uncomfortably warm on high use.
Do you guys think that I have a defective device? I still have 4 days on free return policy with the seller. should I replace my phone?
I'd say it's normal for a phone.
Video recording and running heavy games is the most difficult tasks for smartphone (maybe now it's VR & AR), I'm not surprised at all if the temperature raises at 42 degrees or more.
Benchmark apps like 3D marks take full power of computing capability, no wonder why it gets even hotter.

yeah! i thought that too. actually i think for a processor like 835 normal temperature is 35 36. I do understand that Optical Image stabilization and image stitching are quite heavy tasks . maybe im paranoid. I just want to make sure it doesnt damage the phone in the long run. Also its kind of a pride thing . you see from where I am, There are tonnes of pun and memes about cheap MI phones and heating. So people around here were like you have a $700 phone(thanks to all the customs and import duties) and it heats like a $50 MI phone?. *smh*.
Do you think installing custom rom can increase performance? I really want to get rid of that HTC companion, news republic, facebook and messenger. FB sucks. it takes up almost 300MB of RAM at all times.
It would not damage your phone but as we speak of the "long-term", something you probably should know:
If you keep using your phone for heavy tasks and temperature of the device is always at 38°C or higher, it could decrease the battery life. Higher temperature would cause the loss of battery capacity. You probably should be careful.
As for MI phones, 50$ is hard to get one. And heating meme is because of Qualcomm S810 back in 2015, for HTC, Xiaomi, as well some other devices. Some people just couldn't get over it even we have S835 today.
For RAM consumption, I'd say leave it, because on the one hand, U11 has 4GB of RAM, 300MB does no harm. (the theory is, the free RAM is some sort of a waste, you don't need to be careful about the RAM usage as long as you don't experience serious lag) on the other hand, you can always disable the apps if you don't need them. Installing another ROM won't make these apps running with less RAM.

Hello. I'm new with the account here, but been reading this forum for years.
I'm creating this thread because my new Nexus 5 (which I have for 20 days now) is overheating more than a normal mobile device should.
When i bought it, it had 4.4.4 Kit kat android, and I had that one for about 5 days, and in that time, I didn't notice any overheating, or maybe didn't pay attention, can't remember really.
But after installing official Lollipop 5.0.1, the device is heating pretty good even when browsing internet for 5 minutes, at about 30-40% brightness.
**** Please tell me if some of your devices are acting the same, and is it worth a try to install back an older android to try if it will stop overheating, or my device may be faulty and should I take it back for another one (or maybe switch to LG G2) ?
Because I'm still unable to post image links, i will write it down:
- Ambient temperature: 23 degrees Celsius
- The temperature sensor is taped on the back side, at the side of camera, this is where it overheats most. (even if not using camera)
- Phone temp after staying on standby with screen off: 28 C (it's not warm but it is warmer than desk which it is sitting on)
- After staying idle on home screen with screen on for 10 minutes (50% brightness): 30.5 C
- After chatting on Messenger for 10 minutes: 34.3 C (feels warm)
- After recording video for 4 minutes: 41 Celsius!!! (almost uncomfortably hot in the whole upper half of the phone, both the back side and the screen)
- After 15 minutes letting it cool down, with screen off of course, it is 38 C (still hot to touch), and it stays like that untill I reboot the phone, then it cools down.
The test took about 50 minutes, and after that, battery was drained for about 25%.
-While charging, the phone does not overheat, just gets a little warm which is OK. (haven't tried wireless charging)
P.S. I don't play games on the phone...
Please act quick in case I should return the phone...
the only time my phone gets hot is when im intensively doing a lot of things..
for example.. im playing ingress, have tether ON, and my two sons are using their tablets connected to my phone playing ingress too..
but if i turn off the game and turn off tether, it cools down..
to me it sounds u have something intesively using your CPU and perhaps GPS and other radios.
hold power button.. when PWR OFF shows, long press it and reboot into SAFE MODE...
use the phone for a bit and see if it gets warm... this should tell you if its apps installed.
I only used wifi, no tethering, no GPS, 3G, NFC or any other radios, cell signal is good so phone is not searching for it.
- In safe mode, it still gets warm when using camera. When browsing internet and watching images in google search, also but just mild warm..
- But after sitting and thinking, I've found a problem! After recording with camera and leaving it to cool down, it didn't cool down because it had to make an effort to upload that 5 min video on Google drive via Auto backup!
After turning the Auto-backup off, it is now much cooler!
I will post tomorrow with the results, if something changes...
Anyway, thank you!
First of all, "warm" doesn't mean anything.
Battery temperature does not mean much either, as the CPU is what generates the most heat.
There is a battery temperature throttle that reduces the CPU frequency, but it is almost entirely pointless as the CPU will always reach it's own throttle temperatures MUCH, MUCH earlier than the battery will. The CPU starts throttling at 65C CPU temp (NOT battery temp), and shuts itself down at about 105C CPU temp. Unless your battery somehow reaches a batterytemp of 70C+ (nearly impossible because the CPU will always hit it's throttle first), then I would never even take it into any sort of consideration unless you have a physical battery defect.
Using the camera generates heat since it's CPU and power intensive.
Using the phone in general will generate heat.
Keep in mind that mobile devices are passively cooled, not actively cooled with a fan/liquid.
Not sure what you're so worried about.
Lower your brightness
Lethargy, thank you for a short physics lesson. I'm already into physics and cooling systems so all is clear. I was just worried a bit because all of my previous phones weren't getting this warm (hot), but also never had a multi-core processor in phone eather, maybe that's the reason why I never experienced this before.
Battery temp (measured with app) gets up to 40-42 degrees Celsius, while the phone case gets up to 41 when recording video. Of course that temp won't damage the device, I'm not worried about the processor, but that temp is degrading battery life, in long term.
And about the brightness, phone is not meant to be used at lowest brightness all the time, so that shouldn't be an excuse for high temps. Just sayin'...

The only thing that sounded odd was how it wasn't cooling down until you rebooted, but it sounds like you figured that out with the automatic upload setting.
41-42c battery temp can be normal after prolonged usage, though personally I usually see that after a short gaming session. My brightness is around 40% and high brightness will cause extra heat.
Otherwise the phone is very thin so you can feel the stacked SoC and RAM heat up through the skin fairly easily, right around the camera area as you mentioned.
I think each device and CPU is slightly different and can vary by a few degrees under load as well.

Your temperatures are fine and you shouldn't worry about it. It's average for a Nexus 5, and there are throttles/shutdown temps anyways, for both the battery and CPU. I've had mine for a year and there hasn't been any sort of issue, normal usage should be negligible to the condition of the battery.
Ok, everything seems to be ok then. Now I can go to sleep without worrying Thanks guys!

Does it get hot under normal usage? How much degree celcius are you getting while doing basic task and watching video?
No no heat problems on mine. I believe Sony has introduced new technology for the heat problem.

Nope no signs of phone getting warmer. Played perfectly fine.
My XZ or XZs didn't get hot or even slightly warm, exactly the same deal with this, I would say it runs even cooler!
That link only offers me a max of 1080/60 not 4k

Well, I have been testing my XZP for two now. It is getting warm - definitely. If you put it under extreme load, it´s getting warm, even that warm your palms get a little sweaty - but not uncompfy warm. My LG G4 in comparison got that hot you´d barely wanna touch it.
Look for an app on Google play called "epic citadel" and run it.
Left it going for about 30 minutes and walked around a bit. Phone got Luke warm. Used 8% of the battery.
Not so much hot to me
Sent from my G8142 using Tapatalk
Any and all computer(s) CPU's will get warm to hot depending on the load. This is the nature of the beast. But mine does not get warm at all the way I use it. My battery life is phenomenal!
Gets warm if you play games for a long period, but nowhere near hot. Also I noticed that, compared to my old phone, the warmth is pretty much the same on the entire back. It's not just hot where the chipset is. All in all, the phone is awesome regarding heath control.
The phone does get hot after a while.
It's cool most of the time, and even if it gets hot, it has great cooling so leaving it alone cools it off in minutes.
As for the temperature, i was doing a stress test the other day (3D) and the phone seems to have capped at 38-39 Celsius degrees (that is slightly higher than body temperature so you can definitely feel it). I didn't check temperature after that though.
It also gets warmer while both watching and shooting at 4K, or high speed (even 1080p though).
However trust me, if you had the Z3 Compact like I did, that phone was a freaking furnace. My battery was affected by it. If want to use my Z3C as a gps in my car, i have to shove it in front of the AC to keep it cool otherwise I'm afraid it's going to evolve into a Samsung Galaxy Note 7.
So this phone is a big big improvement. Though I'd like a phone someday that definitely doesn't get hot. But maybe that's too much to ask.
As I'm typing this, after about 30 minutes of active use, my battery is 35 celsius degrees. From normal use.
A cell phone is just too small to dissipate heat in a very efficient manner. That is why super fast, and powerful, gaming desktop PC's have several fans installed in them along with huge heat sinks sitting right on top of the CPU. The heat sinks are larger than this entire phone! I am an IT Systems Engineer and if you've ever had the opportunity to go to a large data center where servers are housed you will quickly notice the high volume of moving air in the entire area. It can even get quite cold in some data centers all for the same reason... Computers can get very hot! So the fact that OEM's can keep these things as cool as they do, with the CPU housed in such a small, airtight space, is really a marvel of engineering.
Hello , the phone doesn't get hot like my z2 is used to be , I've managed twice to get the phone (on purpose) , but with normal usage 4K video / gaming etc it won't get hot unless you spam many task at hight speed
When I'm playing games such as Asphalt 9, PUBG or shadowgun legends on max resolution, max brightness and bluetooth on my Oneplus 7 pro's CPU temperature gets really hot, like really hot 73 degrees Celsius when playing for only 30 minutes. The weathers temperature is 17 degrees Celsius. Below is an attachment of the CPU's temperature graph. The screenshots are made a minute or so after closing the game Shadowgun Legends. I'm kinda worried of damaging the hardware with such temperatures. Is it normal to have such high temperatures and does it damage any of the hardware inside? And does anyone experience the same issue?
This just in! Playing graphics-intense games on a phone makes it hot! More at 11:00.
u should have gotten nubia red magic 3 instead.. op7pro is an allrounder.. perfect for modding, camera, display king etc.. it games good but if u want to replace your pc gaming with a phone u should have gone with red magic.. that thing is MADE SPECIALLY FOR THAT.

I really like the phone but as you say oneplus 7 pro is an allrounder. I don't play that often to buy a phone specifically for gaming but I hoped that the 10 layers cooling in the oneplus 7 pro would work a little better.
For some reason the 7 pro is set to throttle at much higher temperatures than normal, I suppose in order to preserve performance but it gets too hot and battery drains horribly fast. Personally I think they should adress this because above 50 is just too much even directly on the SOC, there have been situations like this in the past and they were adressed accordingly.

do you know anything about silicon? these chips can stand over 120 degrees celsius.
the SOC isnt something i'd worry about, maybe the other components, but still 50 degrees is perfectly normal.

I think I should ask you that same question. It's definitely safe for the cpu to go as high as 70 C, but that heat needs to go somewhere and it will fry you fingers, so it's not really great for the user. Your 120 C claim is bollocks, you won't get close to that with any phone component, especially with newer ones, as the lower the process node, the lower the throttling temps are set(at least ideally). The 7 pro doesn't throttle as much as other devices, but it sure gets hotter than them, as anandtech has noted in their review.

i said they can STAND that temperature, not that should get to that temperature.
IMO anything under 60-70 degrees C is safe. if it starts to climb above 70 then i would think something is wrong.
also OP phones have throttling at higher temps, it took 65 degrees for my OP6 to throttle down.
my Pixel3XL would throttle at 45-50 degrees (idle on them was 35 so its nonsense)
I know so many oneplus 7 pro users but you're the first person I've come across of this issue... I'm facing the same issue its even reaching 80°c on my OnePlus 7 pro. it wasn't earlier but this problem came after the latest update and i tried downgrading but it didnt help either so I'm pretty sure its a software bug.
Since there are only a few people OnePlus has not addressed the issue yet just make this issue more popular.

73° is nothing... youre phone cant overheat, it will throttle down to prevent overheating... just play and have fun.
My phone is One plus 7 pro. While charging batter get over heated at 48 degree celceius. I got the messgae display to shut the power as it will not charge the battery beyond 91%. So there is auto temp set us in the phone to take so much heat.
thanks to Oneplus design strategy.

Hey everybody,
Since I work at a phone repair shop I have access to a lot of little parts and things to do modifications to phones.
Lately I've been thinking of taking a heatpipe from something, and slapping it into my Pixel 3 just to see what kind of difference it may or may not make.
I have a heatpipe from a Samsung S10 already pulled just waiting for install.
But I'm hoping some people can chime in with the temperatures that their stock pixel 3 devices generally reach, so that I can compare after the "mod".
Preferably three temperatures:
Idle
Load (Video)
Load (3d game)
And if your feeling generous a fourth temperature from using a CPU burn in app.
I'm currently using CPU monitor to check my temps, so using that would be prefered so that there are no different temps between apps.
And yes I realize this won't be a perfect test due to what apps everybody may have running in the background, but ballpark figures are better than none at all lol
For reference my temps stock:
Idle: 31°-33°
Load (Video): 35°-37°
Load (3D game): 36°-40°
Ok so the heatpipe has been installed since later in the afternoon yesterday.
The heatpipe has cooler Master thermal paste on either side to help heat transfer.
It sits directly under the motherboard, and runs underneath the battery.
Initially the temps were a little worse of course since the thermal paste had to "set"
But I now have some base figures.
At idle: 25°-31° (this large variance is likely due to background apps updating/running such as Facebook, messenger, email and ambient temperature however it mostly sits around 29°)
Load (Video): 29°-34°
Mostly used YouTube, but watched a movie on Netflix
I did have a 3 hour google duo video call with my favorite lady. After about an hour and a half the cpu hit 47° and stayed between 45°-47°
Fairly hot, but prior to this I've seen it hit 49° on a duo call so I'm not complaining.
Load (3D game):35°-37°
Obviously this one is subjective due to the game, and what settings it's on. Though temps didn't seem to change much.
One thing I have noticed from all this is that cpu monitor also tells you your battery temperature, and weirdly enough the battery has actually gone down in temp 2°-3° from where it would normally sit.
What I mean is that at stock the battery was usually 1°-2° celcius higher than the cpu temp. Where as after this mod it usually runs the opposite 1°-2° lower temp than the cpu.
Hi, I want to buy the Rog 5 but I've heard that it has high temperatures even from light use (like when using YouTube it reaches 40degrees celcius). How are the overall thermals? I'm not talking about throttling I'm talking about general temperature when using the phone for light tasks. Any info would be highly appreciated. Also any info on battery life would be great too
From what I have heard from Youtube and reddit, It is a hot phone because it keeps internals in a good temperature, plus they achieved better temperature after update.

But having a warm phone isn't a good sign is it? I'm currently using a huawei p40 pro plus and it's super cool (probably because of the ceramic body). You mentioned an update, so is the rog 5 cooler after the update? On YouTube Technick ran a battery drain test and the Rog 5's peak temp was almost 60 degrees celcius

Thanks man. This really helped.
I got it a few days back, I can share some impressions. Yes, it's a hot phone. Yes CPU temp gets up to about 40 degrees sometimes when browsing or multitasking. Gaming also gets it to about 45 - 50 on CODM and Dead Cells and between 55 and upwards of 60 with Genshin Impact. A Peltier effect cooler like the FunCooler from black shark brings this down about 10 degrees. This temperature is mostly felt at the center of the display, while the sides on the back, where the batteries are, remain noticeably cooler. Perhaps their goal was to dissipate het through the display, idk.
I haven't been able to notice any drop in performance yet, even with the thermal limit set to low. What I don't know is how this affects the chip long term, but I hope it doesn't degrade for at least about 5 years. Either way I'm sticking with a cooler for Genshin impact just to make sure the device lasts longer.

Thanks for the reply. 40 degrees from just web browsing is ridiculous. Rather dangerously high and will definitely degrade batteries. Think I'll give the rog 5 a miss

40 is the CPU reading I get. Batteries stay about 5 degrees below the CPU for normal use generally according to my observations, just to make that clear. Not sure which battery temp it's actually reading though, since there are 2 batteries.

40 is still too high though for normal usage. I've never heard of a phone go that warm. My huawei sits at 22 maximum.
Phone arrived 2 days ago, in my experience It Is not that hot, while browsing / YouTube / Instagram It Is cool (about 31/32 °c) and my ambient temperature Is around 20 °. I have played 1 hour call of duty and It reached 37 ° on the cpu, while the phone was hotter, especially in the middle. I think this Is how It works, getting hot outside to be colder inside. Also I updated to firmware 2102.81 which helped a lot.
