Hey all,
As of about a month ago, my beloved Nexus 5 has been getting extremely hot to the touch. As a result of that, the device is uncomfortable to handle and is dying quite quickly. As this was a factory refurbished I got from eBay, I had no warranty on it. I read a thread on here awhile ago that Thermal Paste could help with heat on the CPU, so I decided to try that as I didn't have a warranty to void. That did help with the temperature on the CPU, but because Thermal Paste is a conductor, all the heat dissipated into the screen, essentially making the screen a mini stove. I then heard that Thermal Pads might work better, so I ordered some off of Amazon and applied them to my CPU. This helped with idle temperatures, but as soon as I touched the screen they raised back up again. I've tried everything, CyanogenMod 12.1, CyanogenMod 13, CAF ROMs, and I even flashed it back to stock. Nothing works.
Now for the odd thing: Idle Temperatures are normal, at around 38°C. Load Temperatures are fine, it reaches around 65°C under AnTuTu's Stress Test. However, under normal use such as browsing Chrome or watching YouTube, the Temperature IMMEDIATELY goes from Idle up to about 58 °C, and stays there. The phone loses battery rapidly, and it burns my hand using it. I've checked for CPU hogging apps, there were none. I made sure I was on the correct CPU Governor, and I was. Even on the Conservative Governor the Temperature was still going up to 58° C.
I have no idea what is going on. I might have an idea, but I don't know if it's even how the phone would work. My battery has been acting up lately, even before the phone started heating up. Some of the times when I've taken the phone apart, I noticed that the Battery's Ribbon Cable sparked a bit. With this and the fact the the battery has been acting up, it leads me to believe the the battery might be unstable. Could the battery be delivering too much power/voltage to the CPU, causing it to heat up? Just a wild guess
Help would be extremely appreciated
its battery issue. try changing it

I find that frequently my Q runs hot. There doesn't seem to be a pattern to when it happens, but often it's hot enough that it's a bit uncomfortable in my pocket. Anyone else?

Before I turned off LTE the phone got extremely hot, since then it's only occasionally reached uncomfortable levels (~104F battery temp according to my widget) and each of those times was when I was in a marginal signal area without WiFi data. Bluetooth with WiFi looking for a signal also seems to get it a little hot (maybe 102F), but nothing like the Evo Shift which would hit 108F under the same configuration!
I have mine temps set to C but the other day it got up to like 64 degrees. Not sure what that is in degrees F but I know its dangerously high.
What temp are you monitoring? To me 64C could only be cpu core, which would indeed be high but not dangerous to the chip (my desktop core routinely hits 90C as does my GPU when stressed, I run a minimal fan speed passively cooled rig for noise reasons). Most components can hit 110C internal temp without damage. However batteries don't like getting above 40C much at all, nor does human flesh.

Supposedly that's battery temp. At least according to SetCPU. I figure its off somewhat cuz it reports my processor upwards of 300 C and I know that's not right. But I have a case on my phone and when its reading high battery temps the back of my phone is hot (not just warm)
I Keep wifi off, and when in poor service areas my phone gets hot. If I put it in forceroam, then she is fine.
My wifi is rarely on. Occasionally my temps get a little warm but not too bad. Any time I use wifi tether it climbs though.
Edit: After re-reading arggghhh's kernel thread i realized the kernel i was using has the gpu overclock attempt. Flashed back to version .04 and its still getting a little warm but nothing ridiculous. Haven't used wifi tether yet so i cant report on those temps.
Hey guys,
I am calibrating my battery atm and as you may know you have to discharge your device fully to calibrate the battery properly. To speed up the process I decided to install a stresstest app to my phone and guess what: the phone gets insanely hot, I can't even hold it in my hand longer then 5-10 seconds. Kernel tuner displays me temperatures between 78 and 82°C.
But this overheating problem not only happens with the stresstest. When I start watching videos on youtube or start using my phone for maps it gets hot too (about 60-70°C). It starts to bug me.
What do you guys think I should do to fix this? I already thought about applying some thermal compound between the CPU and the metal shield around it. But I'm not quite sure if it's a good idea. I already have a new phone but I still need two phones because I have to travel between Germany and Switzerland all the time. And this issue starts to make my Sensation unusable.

I would suggest an anker battery. It has a greater capacity and it keeps the battery very cool.

did you try different kernels?

Already using it and I'm talking about the CPU temperatures and not the battery's temperature.
And sure I did try different kernels. Even at stock kernel setting this thing gets hot as f***!

So I just decided to disassemble my Sensation and put some thermal compound on the processor chip. Now I'm not getting over 70°C at full load, 1,56GHz. Pretty good outcome. And under normal use it doesn't heat up over 45°C.
I really have to recommend you this method!
I have two questions.
My Nexus' battery tends to overheat whenever I'm either playing games or charging. From what I've read, a hot battery will shorten the lifespan of the battery. What method do you use to cool down your battery?
This is a simple solution I came up with:
1. Take out an ice pack.
2. Envelop the ice pack with some sort of thin cloth (I used a microfiber cloth).
3. Take out the phone from its case and place the phone on the cloth.
I'm rather concerned about this method because it does cause condensation. However, the cloth applied over the ice pack is supposed to absorb the moisture emitted from the ice pack. Thoughts on this?
Hi,
First thing: can you provide the real temperature instead of saying "overheat" (it's like "it feels hot, warm, very hot, etc...")?
Second: are you sure you are speaking of battery temp and not CPU temp?
Phisically where your device is "overheating" (bottom, center, top right)?
what do you consider "overheat"? how it feels in hand isnt an accurate way to measure temp, as it could feel hot but still actually be cool. while charging, its normal and expected to get warmer. also while charging and using the device it can get significantly warmer. and the chances are that you will long get rid of your nexus before you see any real noticeable battery loss(2-3 years +).
Sure, sorry about that. I'll specify more in this post.
The heat is coming from where the battery is located and it feels very warm.
My phone went all the way up to 46C. (After cooling it off, it's 25C)
As for the CPU or battery temperature, the app I use only states "temperature: ". I'm assuming. it's battery temperature since the app monitors my battery statistics.

46C is normal for battery temp, especially while charging(its not that much higher than body temp, which is 37C). if getting up around 55-56C, then its getting a bit too warm. 60C is overheating for the battery(100C for the cpu).
Nothing to add much as what simms22 said, in any case there is a thermal protection (thermal throttling) and the last protection is a shutdown (for both about CPU and battery temp)...
We have a quadcore device enclosed without any "hardware" cooling system, so under some conditions you can expect some heat, nothing to worry about since there is a thermal protection.
You are on stock kernel? What is your room temperature?
To me your solution seems too extreme and useless ("an ice pack", all day, near you, ready to use it when you reach YOUR temp , stop using your phone in this case...) , search for "heat" in this forum, nothing wrong.
While charging I have something like 39/41 °C and if I use my phone it can go at about 44/45°C for the battery temp. For the CPU temp while charging it can go to 70°C (all browsing the web in Wi-Fi and in 4G it's more, 88°C but with custom kernel and custom thermal settings).
Honestly, your use phone like you want and like you need, don't bother, in any case if you have a real overheat you will know (see above)...
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!

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.
