W Heats Up while charging

hey guys is it normal that our W heats up to about i think 45-50 degrees while charging.. sometimes it heats up too when using the internet via reverse tethering.. just wanna know if its normal, and some advices to prevent it would be awesome.

With Black Notes Hybrid 2nd Gen
Its happening to me aswell getting really hot.
I recently flashed to BlackNotes Rom and when i was charging it overnight for the first time,when i woke up i picked up my phone i immediatly dropped it.
i checked on set cpu the speed was min122 max 1401 ondemand.
ALSO i checked the temp it WAS 60c literally i swear phones should never go over 50c.On stock rom the highest i was every on was 45c playing games.
From then my phone always gets hot with 1401mhz. i dont know why.
With normal use average temp 31c-35c it used to be 27c stock ROM.
I think i sholud get a new battery because 60c is rediculous that could explode it and i thought li-ion batterys have fail safe or something like that for 50c???
EDIT: setCpu 122min 768max and my battery is still 36c im not playing any games im just on homescreen.

WOW. WOW. 60c is too far hot! and yes your phone and motherboard can be burned! When I using BN chapter 2, and when playing games (1401 mhz) the temperature never above 42c, and then I limit the cpu, it will automatically set the cpu speed 245-368 with powersave governor, and screenoff with the same configuration. so when idle, my phone never above 25c (im using arco CM9 now). and I suggesting you to buy a new battery

my phone heat up too,but about 40C only

I've been on the Bionic cow rom for the last few days with data enabled, anyway went to send 4 1.1mb pictures to another email address today and as well as taking around 10-15 mins (2G) it got really got like through my trousers it was making my leg quite hot but never seem'd to get that on original rom
Jamie.

just an addition to my post. i live in the philippines where the temperature is getting really hot this few days. i tried to charge my phone on the office where its about a bit cold and the phone never heated up. are you guys from a cold place and still heats up? if thats the case then my problem is just normal.

maybe you can try download cpu spy from play store and check your cpu time in state. now i'm using bionic cow rom with xxlm8 kernel, the cpu time in state is always 1401 mhz. it's fast but create heat when playing games n surfing!!! i've attach my device screen shot as reference.

sure ill try that app.. my phone heats up too now when im surving using droidvpn.

i found an app that displays the current temperature but only for the battery, i dunno if only the battery heats up and not the phone.. the attached screenshot was the normal temperature of my phone, ill try to upload another once i got time for hard gaming or browsing that can heat up the phone, maybe on weekend.

My phone usually goes up till 4OC. But thats when I use data network and watching movies on the web at the same time. When charging my phone heats up to 35C. Other than that I cant think of any other ways how my phone heats up. But will let you guys know when something comes up.

does your phone heats up while your using it? or just on charging? mine only heats up while charging so i only charge on the office to maintain the temperature, its better to charge on cold places, however if your phone heats up while you are using it then maybe its because of some tweaking that you've done to your phone thats makes it use too much CPU that causes the heat.

normally i play some hd games mostly bcz of games my phones heat up.does it happen to anyone too while playing games phone heat up.if i overclock my cpu and reduce the frequency @ 1.2 or 1.0 mhz i think then my phone heat less

i also play HD games and watch movies, but my phone only heats up when im using reverse tethering(means i use internet on my phone via usb from PC internet) and i think it will really cause heat because of internet and the same time charging while connected in the USB, maybe you made some more adjustments that made your phone heat easily. but if you play for hours then its normal, just for me don't play that much long or less your internal chips will melt.

heating up

while playing games or using wifi for long duration its get heat up? any solution to stop heating???

You can't, when you play games, the cpu needs to run at the highest freq all the time which heats the phone. You could use a custom kernel and set max freq at lower level but this would lead to performance loss.
Or you could mount a cooling unit to the back of the phone.

i guess it's a common when your phone heating up while you are doing something on it, though for some people it may looks scary.
it's basically just like your computer, it will heat up when you play games or doing some extra stuff on it..

for wifi also?

Well if by using wifi you mean browsing web, then the same applies as to games. CPU is at its peak and heats up.

Well ,
This is a normal thing for this kind of phone with hardware included one v.
when CPU work more , it's temperature get's high . it's a nature of any CPU.

How hot is too hot (gt-i9192)

My gt-i9192 can get a bit hot. Reaching even 45 Celsius when I am outside using for example the maps app (needs gps, data and wifi (it claims it makes GPS more accurate and it seems to do)). or a game or browsing the web. Specially if the environment temperature is high (I consider 25º or so "high" for environment temperature). I am not sure if 45 is too much or if it is just okay fine. It does get uncomfortable and the temperature guard app defaults at 40º for the "too hot" warning.

Keeping GPS on does get hot, particularly if you are using a navigation app. Depending on the games, some times it can be also demanding. But if you also get 45 degrees on browsing, than something is wrong.
You sure if the app is reporting the correct temperature? 45º should be warm to hold in hand (a feel-able temperature).

Sure, I feel the hotness.
I used to get 45 degrees while browsing if the environment temperature is hot. It hasn't happened in a while, recently I moved to a custom kernel, so maybe that fixed it.

My i9190 has been getting really hot lately, and whenever it does the battery drains crazy fast (about 35%/hr). Strange thing is, the task manager shows no apps consuming CPU nor RAM.

I had a similar problem with my old S2 that started after I had had it for about 9 months. At the start of a day battery consumption wasn't bad, but if I used it for an extended period of time it would heat up, and battery consumption seemed to rise linearly with the amount of heat the phone was emitting. There were incidents where it drained to half from full in a matter of less than an hour.

I welcome. I have i9192 and at me temperature at the game on facebook also achieved 45 "C and I returned it to the shop. At other users of this phone what temperature is while looking the Internet through??Can the shop he will accept the warranty??

Ah, I did forget one thing, since I didn't stay on original ROM for long. For those that are on original Samsung ROM, I guess it normal, since the default CPU governor is set on 'performance' mode. Your CPU is running on the highest speed all the time, and most original ROM does not enter deep sleep.
JoeCastellon: If you are on the original ROM, it would be your problem of battery drain. Using a custom Kernel or ROM like vexorian would solve your problem.
groda: Same, if you are on original ROM, running any app even if it not games, it would raise the temperature at a very rapid rate.

I thank for the reply. When install root and to lower the clocking of the processor? by the way, the new ROM will lower the temperature?

My latest "[doh this got too hot]" experience was on Sunday, I was using c0bain's kernel which AFAIK has the "on demand" governor.
I am now trying SilviuMik's ROM, will test during a week and see if the hotness happens again.

Custom/modified ROM or kernel will lower the temperature. Original Samsung ROM - no.

For me a battery is overheating. I want install root and new kernel. I have a question. Which kernel will lower the temperature for me? As install new kernel could update whether I will be through wi fi??

The kernel itself will not magically lower the temperature. You will need to manually undervolt the cores to achieve that, which requires a custom kernel which supports undervolting.
Changing your kernel will prevent OTA updates, if that's what you're referring to with the update through WiFi

My cores are working now on the maximum. install the root can I lower the clocking of the processor this way?
It which kernel will be good for my i9192? What thread is it possible to find him in?

Yes with kernel and appropriate app you can adjust clock settings.
Not sure if 9192 has a custom kernel that supports this. Check the development subforums
Okay found one.

Solution to reduce thermal throttling on Nexus 5X?

Is there a way to reduce it? My phone slows to the pace of a sloth far too frequently and it seems correlated with temp.
I'm assuming that's the cause because when I look at the CPUs in CPUz the last two go down to 633MHz when things are getting slow. Also seems worse with a case but could be my confirmation bias. This is particularly apparent with the camera, Maps, and when coming out of doze.
Is there a more conclusive way to figure out what is causing my Nexus 5X's occasionally brutal performance?
Sent from my Nexus 5X using Tapatalk

Well, what exactly are you doing with your phone that's causing it to throttle itself? I think with a stock kernel the phone begins to throttle and eventually shut off the Big cluster at 36 or 37 degrees Celsius (someone correct me if I'm wrong). If you flashed a custom kernel, most here have had that limit raised to 46C.
Last weekend I used my phone quite a bit for strenuous tasks including Navigation, Google Maps, lots and lots of pictures and 1080P video. The phone got noticeably warmer, but when I checked my kernel management app, the CPU temperature wasn't even close to the throttle temperature. Unless you're gaming or constantly benchmarking your phone this really shouldn't be a problem. Especially when coming out of Doze. The phone doesn't immediately enter Doze, it waits a while and there are factors that play into its decision to even enter doze in the first place (like laying on a flat surface for X amount of time). So when a phone is exiting Doze because of your input (turning the screen on) the CPU should be quite cool (maybe 22+ degrees). There's no thermal throttling there. The Big cluster shuts off when the screen is off for the sake of battery life, so maybe the lag that you're experiencing stems from the lack of the Big cluster being on for the first second or so when waking the phone back up.
I'll agree that the SD808 isn't a stellar chip; maybe even embarrassing. It's not blisteringly fast, but it certainly isn't slow. There are ways to speed up performance and improve battery life at the same time, which I'm sure you'd appreciate. Unfortunately you have not specified if you're running a custom ROM or kernel, so that's pretty much all the advice and information I can give you right now. But, if you're currently running stock, I'd highly recommend you unlock your bootloader and try out some of the custom (and more lightweight) ROMs that this community has to offer as well as some great kernels. That should make a noticeable difference right off the bat. Then you can dive into the nitty gritty details of tweaking and whatnot if you desire. Check out the links in my signature as a starting point. If you're looking for optimization and speed (like I do) then you'll be impressed.

Thanks for your reply.
I switched to ElementalX about a week ago and it may be a bit better now but it's hard to tell. I've also been using a spigen slim case, maybe that is causing heat to accumulate too.
I don't game. My usage is Maps, Facebook, Snapchat, camera, chrome, hangouts, Spotify, and textra.
I use greenify and amplify as well on xposed. Disabling xposed doesn't seem to make a difference.
Can you confirm that ElementalX throttles at 46C and stock at 36C?
I'm interested in your recommendations. When running geekbench it takes about 9 minutes for things to really slow down.
Sent from my Nexus 5X using Tapatalk

If you search the ElementalX thread you can see that the developer, Flar2, was getting very frustrated with the thermal throttling on this device (others were too, as well). You can read through the progression and, eventually, the decision to apply a "thermal fix" or raise the thermal throttling limit. The threshold is 46C now. Confirmed. The stock thermal throttle threshold is 10 degrees less than that from what I've read. I also remember reading that Franco did a fair amount of research into the throttling issue and found that the CPU was capable of going over 50C with no issues (but aren't recommended), so the limit in place now by the ElementalX kernel is a safe one that shouldn't be exceeded. He probably didn't make it any higher so he wouldn't be found liable by any users if they overheat or damage their phones.
I have no experience with xposed and everytime there's a compatibility issue, hard reboots, etc. it's always because of Xposed. So.. Yeah.
I also do not use any tweaking apps that supposedly save battery or whatever. I let the operating system take care of that. I do use the L-Speed app (again, in my signature) to disable certain things like debug logs and what not to speed things up slightly. Again, I highly recommend trying Ubermallow and Phasma Kernel as those have been my choice, after trying many others, for some time now. Also, I'd look into the interactive governor tweaks after you've settled on a ROM and kernel combination that you like. That's where you can fine tune the way the CPU governor on the phone behaves and can really make a difference in battery life and fluidity of the device.
Lastly, a case can make a difference with cooling but I've never really found it to be an issue. Maybe I'm just not hard on my phone enough.

Google just agreed to take back my device so I only have a few days to try things and make my decision on whether to keep the phone or not.
Thank you for your thoughtful responses and suggestions.
Since I started using the phone outside of the case it actually seems much better.
Regarding the extreme slowness coming out of doze, it only occurs when in doze for a long time. Presumably because the phone tries to catch up on all the sync activity that's been paused for the last 12h or so.

I think I'll try your suggestions and remove greenify, amplify, and xposed to see if things improve. I do agree that the system should be managing those things.
Sent from my Nexus 5X using Tapatalk

Yeah, give it a few days. There are many ways to combat the throttling. Got my phone to 41C today while using it out in the sun. The Big cluster is limited to 633MHz at 36C and shut off at 41CC. The 46C built into the kernel is most likely for the LITTLE cluster to start getting throttled. Check the attached pics below.

Thanks. Btw what ROM and app is that?

ROM and Kernel are in my signature. The app for managing the kernel is Elementalx Kernel Manager and the app to add CPU usage overlays and stuff is called Trepn Profiler.

Sounds like the opposite to me, the phone might be slow because of software on the device not playing nice which causes the SoC to work over time (normal computing + rogue app computing) and can cause the device to over heat and throttle.
There's no reason the device should be slow after a period of doze. That tells me the device is having software caused slowdowns that are not related to thermal throttling.
It takes roughly 12 minutes of 100% sustained load (only synthetic benchmarks) to throttle the 2x A57 cluster, and I've never seen the 4x A53 cluster throttle under any conditions including hours of heavy gaming they stay at 1.4Ghz at all times.

Yesterday I was using GPS to drive and Spotify was streaming. The phone got really hot and unresponsive and Spotify began to stutter. Was unable to even launch textra to text someone.
This of course only started maybe 10m into the drive. The phone is fine while cold.
Maybe I have a defective device but my benchmark stress tests give similar results to other people.

this is consistent with my experience. GPS and spotify (actually almost any app used concurrently with spotify) will cause the phone to have horrible lag.
also, don't text and drive

Interestingly, today when the phone was on battery saver it seemed much faster. Maybe more throttling could help things more than less?
Of course not exactly faster, but more consistent and no unbearable lagging.

Yesterday I flashed the stock firmware files other than user data. Unfortunately I lost root and it seems like I now need to reformat data to get TWRP going again but until then I'm fully stock. Does anyone know a way around that?
I haven't done enough testing to be sure but things seem to be running more smoothly for now than they did with root and ElementalX 1.06. However just writing this i can feel the phone heating up and becoming less responsive. The bottom 2 cores are offline with SoC at 36C and CPU at 56C when I switch to devcheck to check. Other 4 cores at 1440MHz.

I've been having issues with thermal as well. Installed ElementalX along with the governer tweaks GhostPepper profile. When charging (this makes the device really hot) music begins to stutter, coming out of Viper4Android.
When not charging, slow accumulation of heat makes music stutter, same software used. Go figure. Maybe V4A is too demanding on the 808 chip, but I fear if this doesn't cut it, then I'll have to switch phones the next chance I get.
Oddly, this happens when screen is off - the music stutterings. I've thought about Doze and battery saving apps, and have disabled Doze for V4A through the battery optimize pane.
The phone constantly loses battery, around 2~5% an hour, I know thats not too much but my previous phone lost about 1% every three hours. This was a Note 3 Neo by the way. Installing Xposed and Amplify, Greenify and PowerNap should help, but I've had stability issues when using xposed. Maybe later.
Oh, and one last thing. My phone's thermal limit is set to 55 degrees Celsius, but it still feels like it throttles at around 39 or so. Maybe EX Kernel Manager isn't saving the changes, but either way... It throttles too much!

That could be because of the custom software and CPU tweaks or your V4A installation. Using those settings always has the potential to cause issues and I would troubleshoot there first.
Minimum CPU performance with stock settings is 4x A53 cores at 1.44Ghz which is still fast. If you've ever use one of the more recent Moto G devices you'd know it doesn't stutter playing music when it's cold and neither does this device when it's hot.

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the OnePlus 3T stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!

Got the phone today, and it feels very cold to the touch. Most of the heat It gained was from my own hands... though it is winter. I then put a silicon transparent case, and after setting everything up I did some google cardboard vr for around 30 minutes and felt a light warmth through the case... barely noticeable.

Mine is getting pretty warm after rooting, making a nandroid backup, and flashing xposed. Not quite uncomfortable, but very noticeable.

My phone has only heated up a couple of times, and that was when I really used it, games and such.. Otherwise it's really "dead" to the touch.

If you want to heat it up, use some benchmarks, or if you want to be more productive, use mapillary outside and photomap your area around.

Yes.. it's getting heated very often even I use for 5mins.. I got phone today only(23-12-2016). Please suggest a solution.

For me its exact the same thing...

Of course its gonna heat up if your cpu and gpu are working at max speed all the time.. its normal
First day when I flashed custom rom, installed all apps, rooted, twrp and all that it was hot to the touch because the reason above but now when I use it in a normal way its actually cold to the touch most of the times and I love that

I rooted mine and installed a rom really got hot then I changed to a different rom and it is very cool now.

OnePlus 3T is a really cool device. I suggest users to buy it. It has very cool features like Fingerprint access, Camera etc.
But if anyone gets Official TWRP for Android 7.0 for OnePlus 3T, Please tell me*

Never felt any kind of heat through the case (Orzly 2-part case).
Never been an issue.

i have noticed it's evenly warm when it shouldn't be. try enabling "Auto close high power usage apps" battery options.
the description makes me laugh. engrish.
"When it runs, the system auto clean up background power-hungry apps , prevent phone from getting hot."

It doesn't warm up much, if at all, for me, but I am using a rom that underclocks the CPU which could be the primary reason for this.

On 3.5.4 I would have occasional heating after a phone call. Battery stats would show that the phone was using the CPU for extended periods after the call had ended. Usually a deep clean of the ram would solve it. Sometimes it didn't solve and then a reboot would solve the problem. Phone was completely stock.
It was comparatively very cool throughout with the CPU temps being in the mid 20s or low 30s even during charging at 3.4A with the dash charger!

Heating issue
Got my phone few days ago its heating when i am playing clash of clans but otherwise no issues in normal mode.

Nvm

The phone stays cool to the touch even under heavy gaming. (Max 35C on cpu)

Heating hasn't been an issue so far. Had an app causing constant 70% CPU usage and the device was just slightly warm

my phone getting hot sometimes idk why

Any manufacter could make a super cool phone by just setting an agressive thermal profile. Oneplus 3/3T doesnt throttle at all, not with gaming. The phone gets warm, but you have to consider that it's using his full potencial. I prefer a hot phone (not the case) than a cool phone with half of the power the soc offers.
