[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!!!

From yesterday, my nexus 5 is overheating. I controlled CPU and Battery temp with "Trickster mod" app, WITHOUT APPS RUNNING battery temp is 35°C and CPU temp 47-49°C. I cannot understand what's happened??? Until yesterday it wasn't overheating. My n5 is rooted but stock, with Default Franco Kernel (the same configuration i had in past months).
Can u install this app and control your TEMPS, please?
Can u say me if i should get an RMA and change my n5?

I live in India where the temperature's always between 30-35*c and hence, so is my CPU and battery temperature as well. During the night the average temp drops down to 25 when the device isn't being used.
Room temperature and weather around you play a major role in the average temperatures you get. Could be this case with you.
I would monitor the temperatures for a few days and if it doesn't settle down, I would flash back full stock and use the device for a while to see if it changes.

1) Room temperature is about 19°C, so it isn't the problem.
2) I already made all stock this morning, but nothing changed, it was overheating the same
3) If rooted, can u install Trickster mod app and tell me your n5 temps, pls?

My battery sits at 27-30C when idling. The room temperature is around 24C.
Are you noticing unusual battery drain as well? If so, my guess would be that something is keeping your phone awake and running in the background. Try BetterBatteryStats and see if there are any wakelocks stopping your phone from sleeping.

And CPU Temp??

33C, but I wouldn't worry much about that. It's too transient to be of any use. If I open Chrome it spikes up to 45C+ very quickly, then settles back down.

You don't need root/trickster to get cpu and battery temperatures. Anyways, I'm on a custom rom (AICP) with ElementalX.
I am currently using whatsapp and the CPU temp has gone to 42*c and the Battery temperature is showing 33*c.. Room temperature is about 26*c.
As stated above, could be a app which is preventing the device from sleeping. Install wakelock detector and see the culprit.

lmao!
overheating? what world do you live in? you do realize that your body temp is 37C on average? so your battery temp of 35C is still cold! and a cpu temp of 47-49C is pretty cold as well. the safety shutdown for cpu temp is 105C, quite a bit away from 47-49C. your temps arent even halfway there! what you should stop doing is freaking out, and start enjoying your phone. speaking of, you own a quad core phone, when you use it, it will get warm. and if you use the cpu intensively, itll get flat out hot! and thats normal. our phones do not have anything to cool off their cpu, so it relies on the surrounding air to cool it off. unlike a desktop or laptop, which have active cooling systems.

Sorry, but now with 2 simple apps, battery is 40°C and CPU 65°C. When i call, my ear is boiling!!!

safety doesn't mean good. If laptop is a little overheating it doesn't matter, but smartphone overheating is unconfortable....

boiling, i doubt it. boiling point of water is 100C. yes, 65C for a cpu temp is warm, but very normal. and feel, doesnt measure temp. all feel does is give you a difference between what you are touching and what you used to touch. feel is very inaccurate when it comes to a temp reading. boiling is an exaggeration by you. when dealing with real stuff, exaggeration is looked down upon. the cooler your skin is, the warmer your phone will "feel". but that says nothing about temperature. when talking temp, your phone will never be cooler than the surrounding air temo, unless physically cooled down. itll only be warmer, if screen is on, and even warmer when in use. and if plugged in and in use, expect to see temps up to the 70s-80s C.

theres no such thing as a little overheated. its either overheating or not. just like a woman is pregnant or not, shes not a little pregnant. again, i know that you are refusing to believe it, and are looking for someone to confirm your beliefs, but you wont find that confirmation, bwcause your phone is normal. if you want a cooler device, sell your quad core phone and buy a lower cpu speed single core phone.

Maybe 65°C is normal in a laptop, no in a smartphone. Before yesterday it wasn't warm, now yes. Why? Wasn't it normal before yesterday? I don't think.
Configuration is the same, apps are the same, all is the same. I think there is an Hardware problem. I wish see u phoning with a warm display on your ear.

guy, quit fantasizing, THERE IS NOTHING WRONG WITH YOUR DEVICE!!!!
it was warm many times over, you just didnt pay attention to it, thats all. and dont tell me it was never warm, unless you live somewhere in space near absolute zero. IT IS NORMAL FOR THE PHONE TO GET WARM, AND EVEN HOT, WHEN YOU USE IT! why do you think no one has told you that your phone is not normal, that the heat is not normal? because that is not true. you can believe whatever you want to believe, i personally dont care. but in reality you do not exist it appears. lol! anyways, here is my phone, its much hotter than yours(99C cpu temp, -1 degree C from boiling water), and its one of the top n5 in these xda forums..

ok, your cpu is really hot. And your battery temp? Maybe battery is the problem. Don't u feel very unconfortable phoning when your smarphone is so hot?

@simms22 I feel where you are coming fom. I know these devices are supposed to get hot. However 99 C is a bit too high considering you don't appear to be doing anything with your phone in that screenshot. I would expect those temps if you were gaming or using G Maps and streaming Pandora at the same the or something.

Im part of trinity kernel, and I do all the testing. part of my testing is pushing it as much as I can, so I can try and "break" the kernel. i actually spend a lot of time around that safety shutdown temp, trying to break things :angel:
under normal conditions, you won't ever see 99C. but seeing it in the 70s and 80s occasionally, especially while gaming, is normal.

if I made a phone call at 99C, I probably would feel uncomfortable.

My N5 dose the same as you

Please, so why trickster mod say to me that "battery is too much hot"? Now it's about 45°C, and I have only 2 light apps opened, no games ( chrome and play books).

I wiped the cache and the problem is solved

Thermal dissipation

I've noticed that on heavy usage the cpu temp raises up to 41C with core control or about 45C without offline cores. These temps are quite OK for the 808 however the touchscreen in front of the SoC is too hot even with 40C but the back cover is OK. Other devices tend to go above 50C without too much heat on hand. Have you the same problem?

The top front does get noticeably hot yes. I don't know if that's a problem. All seems within normal operating temperatures. Guess it might be slightly uncomfortable to the touch.
I think the reason you typically don't feel it on other phones is because the screen is usually indented a bit deeper and the digitizer is usually thicker glass.

Me too I'm also worried is it okay for the hardware ? Or it will it get damaged because at 41°C the phone becomes really hot

If you're worried about hardware failure, you would need about double that temperature to get into the danger zone.
The phone has temperature control built in, so you shouldn't have to worry about operating temperatures unless you're leaving it out in the Sahara or something

After watching a tear down, it seems that they designed it like this. The SoC is placed on a metal frame above the LCD so it can dissipate the heat quickly because of the glass.

40 isn't that hot.
Mine goes up to 69 that is insane hot.
With Max brightness while gaming.
Thermal tweaks didn't help.

You are so lucky....mone just thermal throttling and fps in games drops to 10-15

any kernel for p9 Eval-19 disable thermal throttling?

i would be glad if someone provides this so i can play more on my phone p9 is pretty sensitive

check this out: http://forum.xda-developers.com/p9/help/huawei-p9-overheat-protection-feature-t3441315/
As i already stated over there, if you disable termal throttling you will not get better performance, well, actually you will, for a whole lot of 15 minutes, then you get a dead phone.
Termal throttling is there for a reason, if the components get too hot they will get damaged. If you want to disable termal throttling, you need to improve heat dissipation first, and, as far as i know, there is now way to do so.

well trinity kernel tool exist but its way too old, no new update, trinity kernel tool where u can optimize voltage disable thermal throttling etc., my phone slows down at 39-40 sometimes even at 36 when i know my phone can handle maybe like 45-50 without damage.. ive seen old posts on LG phones where there is a kernal.zip with thermal throttling disabled and you can install it. i know it can be disabled but havent found any links for p9. i was just posting here to by chance get some from the devs here. i can control my phones temp i can cool it off on my AC while playing, i just want it to maybe if not disable it then set its throttling lvl to like 50degrees because i think the p9 throttling is set to a very low trigger point where it could be higher and still be OK

You know? You think? I'm sorry man, your knowing and thinking, unless based on official documents of Hisilicon, is just that, guessing, and it's not worth anything.
Just because some LG smartphone could do it, it doesn't mean it can be done. Also, you need to take into account the manufacturing process, the same chip could handle different temps if not built by the same company, or even if built by the same company, all the chips are different even if they are pratically the same. Guess what happens if you take different chips, or even different smartphones...
Termal throttling is not there to bother you, it's there for safety reasons, if the temperature is any higher than what the manufacturer had intended you could cause a lot of permanent damage.
Also keep in mind that if you disable termal throttling you will keep increasing the temperature, as the heat produced is the same at any given time under costant load and the passive dissipation system can only get rid of a small amount of what you produce (that's why it needs termal throttling at all), which means that if not stopped at 50C, your phone would just reach 70, or 80, or even 100C in a small time frame, and just keep rising until it eventually dies. Also, the throttling could even be power based, perhaps the battery is too hot, so if you keep going it could even "blow" up.
If you take into account undervolting and underclocking perhaps you can achieve the same result, but termal throttling has to stay.
I hope that explains it, so rather than asking for a kernel without termal throttling, ask for one with undervolting, it makes much more sense.

no, you're wrong. cpu will safe at 100°C, cpu far away not enough warm the battery and kaboom. and voltage is set too high so phone become too hot in a short time it scaling to max frequency, max voltage in voltage table is used. temperature is closely related to voltage, not about cpu frequency. many manufacturers always set the voltage to too high, this is what causes overheating, I have undervolted and overclocked: I get 3 things: phone always cold cool!, huge battery life and speed of light as I want, I'm very please about it when I can control my phone, also my pc

Question Pixel 7 Pro - Overheating issues

I'm facing overheating issues while using video call on my pixel 7 pro. So scare for this temperature 45*C while doing video call. My old pixel 4xl has no issue so far, still working fine.

Mine is at 35c in my pocket with the screen off listening to music. Battery draining like crazy.

Damn it.. so my old pixel 6 pro always over heated and I just purchased a pro 7 was hoping it wasn't over heating and well

Gotta wait for the pixel 12 pro

Over what? 36C* is not over. At least no visible throttling.. winter is coming

I must be good then. I'm at 29.8C while using my phone

A factory reset solved my problem with overheating and draining the battery.

The only video calls I use are WhatsApp, which I've done a few of on this phone. I've noticed they result in a slight increase in temperature, but no more than 38/39 degrees after about 10 minutes.

After the factory reset I made a clean instal of everything. I only migrate some videos with nearby function. Maybe you should try a clean instal without migrating your stuff first.

I just unlocked my Bootloader, setting things up and this phone is hot as hell. Hot enough that the Flash is disabled

My Pixel 6 Pro used to hit 45c if you broke wind and it heard you, thankfully my Pixel 7 Pro does run significantly cooler but video calling does seem to be a bit of an Achilles' heel of Tensor. Video calling however does push the radios, the camera and the processor so it is going to heat up innit and if 45C was too hot the phone would shut its self off in self preservation so is it really anything to worry about?
I am not saying this is the same with Tensor but the latests Ryzen processors are designed to hit a thermal limit rather than a power limit so they instantly hit 95C under load where as previously 95C was an absolute no no, you're going to kill the CPU so don't go there, maybe this is just the way forwards.

The problem is the battery can't really exceed 45C without starting to degrade. And obviously it wouldn't be possible to hold a phone that was dissipating 95C worth of heat through the body lol.
That said, I did a video call today on Zoom for an hour and the phone didn't heat up even as much as my old 12 Pro Max did. I checked AccuBattery and the battery was around 38C which is like 1-3 degrees more than the normal usage scenario I've been experiencing and far from being concerning.

Thing is the P6P hit 45C as regular as the tides without worldwide outcry of the phone or battery being damaged, you just had a lot of people (generally in very hot countries) saying my phone is too hot and i have not really done anything, it is hitting 45c all the time and my camera flash has been turned off.
Mine used to hit 45C just sat in my pocket when i was outside in the summer and i am in the UK where at 25C everyone is melting and moaning they cannot stand this intense heat while the rest of the world laughs at us for flapping on a warm day.
45C seems to be a magic number, it is always 45C and you very rarely see it go higher, 45C sounds like a thermal limit to me and maybe just like Ryzen this is how Tensor is set to run, hit the thermal limit first to maximise processor efficiency.
Of course i am probably very wrong as this is all speculation on my part, the reality is Tensor just runs hot like the Exynos processors it is based on I'd have thought.

My brother-in-law has a Pixel 6 Pro, and when I showed him my 7 Pro on a family gathering last weekend the first thing he asked about was the heat levels. He said he loves the 6 Pro, but the overheating on it is ridiculous. He said the phone was basically unusable when we went through a heatwave in the UK here a few months back were 40c was hit in a couple of locations.
My experience of the 7 Pro so far (I've had it just under 2 weeks) is 95% of the time it will sit between 30c and 35c in normal use, and occasionally tip towards 39/40 if you do something which stresses it. I've had it go over 40c on one occasion but that was after 4-5 reboots in 5-10 minutes when I was messing around with various settings after rooting it. Overall it's been more than reasonable for me.
I also strongly recommend sticking the CPU governor on schedutil.

May I ask why and what is the differences in your case?

Once activated I found my phone spent more time closer to 30c than it did 35c under normal use. And for what I use the phone for I noticed no performance hit, although that might differ for others.
It's also worth pointing out that, phone SOCs, like other silicon, can differ in quality. So one 7 Pro could run a task with the CPU at 33c and another seemingly identical phone run it a degree or two higher or lower.

Are You using any custom kernel or just default one?
