What are your CPU and batt temperatures?

Just wanna ask around to check if I'm the only one who feels my phone is a tad bit too hot?
Usually when not charging , the batt temps are around 34-38°C, with the CPU in the range of 38-45°C
When charging the batt goes up to 38°C - 44.7°C or even overheating in the 45-50°C range( ok this would be my fault in using heavier apps)
And the CPU would stay in the range of 40°C - 55°C even without use sometimes

Those temperatures aren't out of the ordinary for this device, that's pretty normal actually. I've had my battery temperature go between 50-55°C fairly regularly, and even as high as 66°C without the phone shutting down (I did cool it down very quickly upon seeing how hot it was though).

Thanks timmaaa, for a moment I thought I was the only one.

I use Battery Mix to record my temperature vs. Battery % over time (use the JB feature to disable its persistent notification): https://play.google.com/store/apps/details?id=jp.smapho.battery_mix&hl=en
One thing I've noticed is that when it hits 40C+, the space below the camera becomes extraordinarily hot! This happens at least once during a work day, especially happens when I don't touch the device.
When this happens, the drain rate just plummets (when I refer to the battery level slope vs. the phone temperature). However, a reboot fixes the heat (and as a result, the drain rate) over a lengthy amount of time.
I've heard of this, but haven't gotten around to trying it successfully:

That shouldn't happen while you're not using the phone. Have you used an app like BetterBatteryStats to identify what's draining your battery?

well this was previously answered by timmaa i had a similar concern cause none of my earlier phone actually felt that warm...
but when i got a green signal that these are normal temperatures, i tried gaming for almost an hour turns out the phone was hot indeed the battery was around 50+ but still the phone dint shut down itself or showed any inconsistency in its functions!
moral of the story.. it happens with everyone.. my friend has a endeavor it also suffers from heating... its so normal that if u search it in google that "why does ht one x get..... "it automatically completes it in with " get hot"(also for the new One).
if you want to cool it down get SET CPU and create a profile in which select battery temperature/cpu temperature at a certain temperature you don't want your phone to exceed and then set the cpu to a lower speed typically till 1026 or 1134...
but again if u feel its necessary cause doing so will obliviously slow down the device.:angel:

Of course its normal. All computers generate heat as power is discharged. Manufacturers are also packing more and more computing power into these small devices, and in general that means more heat (although there are other variables). And every smartphone is designed to deal with the heat differently, so those might be some reasons why your previous phones did not feel as warm.

true that!!
even i was actually worried before hearing about it being normal from u and timma as well!
its probably htc one x is build that way.
BTW sorry a little off topic since this issue has already been resolved has anyone heard a little rattling sound near the camera region only when the phone is sharked up and down (from screen to back)
this also is a build issue!

Totally normal. Just a moving part in the camera module. Likely related to autofocus as you can sometimes hear a sound when focusing the image.

[Q] Overheating Battery

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)...

Nexus 5 overheating battery

hi all im just newbie who just got this devices and after intense use why my battery always overheated ? im just browse some pagesband playing games. im using a softcase. my rom is stock roited with elementalx kernel
any help will be appreciated

Define "overheating", as in the actual battery temperature. Not "it feels hot".

That doesn't tell us anything. Get an actual battery temperature reading, not what you think it feels like. Most kernel apps should tell you.

I don't pay attention to it myself since I know it isn't overheating. Various kernel apps should give you a reading, hell even Antutu Benchmark tells you your battery temperature in Device Info.
Also, when your battery reaches 60C (or 65C, forgot which of the two), your phone will force shut itself off. Chances are, you're not even feeling much heat from the battery, the CPU usually produces more heat before the battery can even reach that high (some kernels have battery shutdown disabled anyways). The CPU starts throttling at around 60C CPU temp (NOT battery temp), and force shuts down at 105C. Clearly, "warm" is no issue at all.

thank you for the explanation sir .

what temperature does your note pro get to in power saving mode?

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)

[Q] Serious Nexus 5 overheating problem

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!
