Hello. My Nexus 5 has been getting really hot while watching movies. I am using a SlimPort to display video to my TV. I am also charging my phone through the Slimport as well. In the past, my phone would get warm, but never so hot that my phone powers down. I have been using the same SlimKat Rom, so nothing has changed as far as that. Would changing any of the CPU settings help in any way? Thanks.

first off, by hot you mean what temp? CPU and/or battery temp.
now, while you are watching movies, its normal for it to warm up quite a bit. if you add to that being plugged in charging, it can get down right hot. but there are 2 safeties features in place so that you dont worry. first is the thermal throttle, which will reduce your CPU speed to cool down your device. if that doesn't stop the warming up, you have the battery temp safety shutdown and the CPU temp safety shutdown. battery temp shutdown is when your battery reaches 60C, and CPU temp shutdown is when your CPU reaches 105C. but really, just realize that when you are charging, and using your phone, it can get really hot, and that's normal.
It may just be warmer weather which has your phone running warmer then before. Does SlimKat alter thermal throttling limits?

I have been using wireless tether and have noticed my phone is getting really hot, I check and it was at 51 degrees celsius, so I shut off Wireless tether and it cooled. But is 50 degrees dangerous to have it at? Sorry if this is a noob question

Hmmm, that's strange. I use wireless tether almost all day every day, usually with my phone plugged into a charger so the battery doesn't die, and I don't think I've ever seen the temp go above 40C.
I could be wrong, but I believe 50C was the cutoff point for when starting to damage your processor. Are you overclocking at all? If you are, it would be a good idea to set up a profile to throttle down the overclocking when the temperature gets too high (and when charging).
Stock Kernel?? I use mine all the time for hours, I have never seen a temp issue. The Hotspot is a thirsty ***** though, I can watch the battery drop.

Stock battery?
Thanks, Robertus
50 degrees...celcius?
I have Battery Widget app and the temperature always hover between 86 to 105 FAHRENHEIT, and this is NOT using Wireless Tether. Is my phone defective?
Turn your screen off and keep your phone on a hard surface, not a carpet or bed, and it should stay noticeably cooler.

Not at all. 50 degrees Celsius is 122 degrees Fahrenheit. If you're phone starts getting that hot, then you should be a little concerned. Right now, my phone is at 97 degrees Fahrenheit, which is pretty standard.
As always, if you are overclocking you should really have a safety profile set up to force a lower processor speed when the temperature gets high to prevent damaging your phone.
I've had my phone getting uncomfortably hot while tethering in areas with subpar signal strength. Probably something to keep in mind.
These phones can handle temps of ~130 if I remember correctly. Processors get hot which is why company's make.them able to handle such temps. If your phone gets too hot your notification led will blink and your phone will shut off if it does exceed a set tempature (not sure what that temp is but obviously you didn't hit it). Your battery life may take a major hit with these temps but your processor is fine.

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.
My Nexus 5 has been running noticeably hot on idle after the 4.4.1 update. Is this something I should be concerned about? Has this been replicated in any other case? A little worried about this.
hot... what is your cpu temp? hot does not mean anything, its a relative term. if you give us a cpu temp, tben we can say if its hot or not. i say this because many complain about "overheating", then give us a cpu temp of around 37-38C. the funny thing is 37C is the average human body temp, so yhat is in no way overheated.
It peaked at around 45. Which I also read somewhere was the temp at which the CPU would start throttling. Which would've been alright, had there been any load. But it's getting there on idle. Would wiping cache do any good?

45C is well within normal, and not even considered hot. hot would be 65C and higher(if not watching videos or playing intense games). the safety shut down temp is 100C, which the phone will automatically shut off on its own.
my note pro 12.2 temperature gets quite high 40C when using it even if the conditions are relatively cold outside is this normal?
my samsung s3 would heat up too that's why i never closed the cover properly to let the hot air escape.. this made a big difference as it wouldn't go up past 32C even in warmish indoor environments (also i used power saving and lowest brightness). i apply the same principles to the tablet, power saving, lowest brightness or auto brightness yet the top part by the camera at the back i can feel heating up and is quite warm.. is this normal? do you other guys have high temps?
i read a review saying it doesn't really go above 35.6C which is BS as mine goes to 40C. i know because the cover is not open the hot air cant escape so the CPU is running up or the battery is heating up or maybe both. i use OS monitor to monitor my battery temp and voltage.
do i have a defective unit possibly? this might also explain why it reboots randomly however i know for certain when it rebooted the temperature was low as i was using it in like 4C conditions so the temp was under 30C max however now the temperature outside has risen i think that's playing a part. im getting sick of all these samsung issues. their quality control needs to be better or at least create so air vents so the battery can breathe. temperature kills lithium ion and i dont think you can change this battery easily

What you're reading is battery temp, not cpu temp. 45c and below is perfectly fine. As for cpu temp, gaming can bump that up to 80-85c. Thermal shutdown occurs at 105c (SM-P900)
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!
