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!
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.

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)...
Hi, 3 day ago I recieved my Mi4c (3gb) and just after couple of minutes surfing on the net I realized, that the top of the phone is really hot (the bottom was normal). The next day I tried it with game - after just one or two rounds (about 2 minutes) phone got hot again - again at the same area. I downloaded some app and I looked at the temperature after running the game - it showed even 55 degrees Celsia. Is it faulty piece or is it just software issue, which can be fixed by different ROM ?
Under load, the SD808 can get pretty warm.
Add to that the fact that MIUI (in all of its various forms) is a steaming, overheated pile of rhinoceros feces and you have a terrible combination just asking for heating problems.
TS CM13 does a pretty good job of mitigating the software issues that lead to heating.
The phone will always get warm when playing moderately intensive games or when used in direct sunlight on warm (30c+) days.
I found that the miui versions some vendros provide are manipulated or corrupted by vendors,
I suggest you check if your bootloader is unlocked, install a recovery, do a total format (not a factory reset, a full system format from recovery) and install the latest miui,
I had overheating issues and the phone would eat the battery away in less then 12 hours, i did this and im currently going on 39h standby and around 1 - 1.5 hours screen time and i still have 34% of the battery life.
Clean house, start from zero and you might be surprised.
Just installed MIUI 7.1.6.0 Global stable from xiaomi.eu and I like it more tham MIUI 8 already. Plus, phone seems to be a little cooler. Snapdragon 808 is still a hot chip though, so don't expect miracles.
Switched from MIUI 8 because of heat and battery life issues.
I tested different rooms and every room has overheating. The only difference is the time the systems downclock the CPU.
In cm13 I changed the values so it doesn't close the big cores so fast.
But the big cores are still the most time off.
Normally my Temps are between 40 and 60 °C
And that's bad.
Miui doesn't change anything.. Only the time of throttling.
I don't need a phone that throttles itself when turned on.
When I'm home I'll try to open the back cover and take a look.
Maybe I can hard mod it in some way.
I'm facing the same problems here.
I use dual Sim, so I thought this could be the signal usage. But my battery is draining faster and faster. Some times even dropping from 14% to 10% in 1 sec!
When using wifi, the cpu reaches over 50ºC (currently 57-59ºC). MIUI 8 didn't help much.
I'm using my phone a lot, 3G and screen on for long time, but it's dropping from 100 to 15% in less than 7 hours...
Is there anything that I could do?
Install MIUI 7.1.6.0, temps and battery are better, or go Apollo the way and flash CM13 or Slim
I have over-heating problem too. Specially by keeping screen on for several minutes. I'm on miui 8 by xiaomi.edu
The overheating is caused by a ****ty rom some vendors use,
Install the latest recovery, and do a full advance wipe (everything except OTG USB), then do the format,
DO NOT REBOOT the phone, connect it to the PC and copy over the latest miui weekly (i used 6.9.1) and flash it, then see if it keeps overheating.
Apparently some of the malware some vendors install are hard to get rid of, i had weekly, monthly, slim6, Teamsuperluminal and Omni rom installed, and they all showed the same issue. it wasnt until i did this "sanitation" process i managed to get rid of the heat issue.

You found some way to hard mod it ? =) The snapdragon 808 would be very powerful if there aren´t that overheats.
Making some holes in the back cover (get out hot air) or give more space (case is extremly tightly built) ? A heat pipe (passive cooling)?
Things are a lot better using an undervolted kernel. Built one from kuma sources (not for MIUI), I could share if you want.

nice idea with passive cooling
i glued my nhd 14 to the back that helped
no serious i dont have any clue to make the phone cooler with hardware modifications.
without the backcover it isnt cooler. the difference isnt noticable.
i would say how the cpu is build into the phone is wrong.
for me the phone isnt worth it anymore. im moving to a BQ or the HTC10.
why should i use a phone that i have to downclock to a fraction of its performance ?
or i use normally and get throttled after 20 minutes?
and it doesnt matter which os i use any miui or cm version suffers from overheating.
so i think ether xiaomi make mistakes while building the phone or it is just the bad 800 series.
but looking at the lg g4 the picture is the same. so qualcomm is to blame for it.
sorry for this but the only solution is to use a fan on the back OR the better solution buy a better phone ;(
edit:still finding grammar fails
For anyone willing to try this is an undervolted kernel based on kuma's sources and a modified msm8992-regulator.dtsi with lower ceil voltages.
Tested only on CM13 but should work for other ROMs based on CM13. It can make your phone unstable (freezes, crashes), so before you try either keep a backup of your current kernel or simply boot (don't flash!) the kernel to ensure that everything works normally:
Code:
fastboot boot undervoltedk.img
@Ydraulikos
im already using a kernel from kuma (Resurrection Rom) and yeah its very great, less overheating. The Rom itself is slim for less heating too.
But its overheating though while playing 3d games for a longer time.
@kar5ten
..nhd 14.. that would look funny xD.
Yeah the problem is the cpu. Snapdragon 808 and 810 suffering from overheating, 810 more.
But xiaomi could handle this too. Not use this cpu or built better cooling system, instead make it as thin. The most temperatures i have is on the top right. If they used passive cooling like pipe heats for distribute the heat, we don´t have this problem or rather less overheating.
@Ydraulikos thanks i will try this.
@Danny94
i made another test.
i use resurrection rom 5.7.1 with oc kernel 1.12 (intelliactive gov.) custom temp. throttle at 75 C
i opened the back and added aluminium foil .
10 layers on the upper side where the cpu sits and 6 layers above the battery and the cpu. they both are connected.
now i run antutu 3-4 times and i got these results
75899-74012-70371-68155
with max temp of 53 C after those 4 runs.
the idle temps are now at 30 -35 C most time
but i only tested it for 2 hours
@kar5ten
oh nice that sounds like a good idee! And withouth foil wich results you get, antutu - temps ?
The Alumiunium foil could take the heat from the cpu and distribute it over the device, for better result thermal paste as connection between cpu and foil could help.
Maybe with another material (foil) you could improve it as well. The best result you would get maybe if the backcover consists of metal, this way you could get the heat out of the phone, air cools metal. (problems.: back cover can get hot, you can heat back cover with hands[maybe a case])
Care about that foil doesn´t heat up the battery and the metal can disturb radio signals (gps wifi mobile data).
Could you share a picture as well of your modified version here in the forum, maybe one too please how it looks inside. At the moment i don´t have a plan how to open the back cover. =)
I will post some pictures but next weekend. Before I open it again I want to test it.
I don't know the exact results from antutu before I modded it.
First 75k
2nd 60k
3rd 55 k
At the moment I didn't noticed any signal drop or something.

Hi,
Did you have the opportunity to take some pictures of your mi4c modding?
would be also great to have a slight bigger case it probably help with the overheating.
best regards,
John
@patadas I get a new case this weekend. Then I will take some photos.
But the problem is to open the phone

by the way : Xiaomi Mi4c Teardown
http://www.myfixguide.com/manual/xiaomi-mi4c-teardown/
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
