[Q] overheat problem - Samsung Galaxy Tab Plus

I have GT p6200 running Carbon ROM KitKat 4.4.4
And since I updated room ICS I've been having this overheating problem
When I was on ICS the tablet didnt get hot while using WiFi
But when I moved to KitKat I started facing this problem
But if it's not the WiFi could it be the CPU governor ??
Now mine is set on user space
If so what's the default CPU settings for this ROM
Thnx

This is your 3rd post you have posted as they all happen at the same time on the same rom i would have said all of them on the same tread as
Post 1 http://forum.xda-developers.com/galaxy-tab-plus/general/battery-drain-kitkat-t2835925
Since I updated to KitKat 4.4.4 carbon ROM
I've been facing battery drain while using WiFi mostly not during sleep
I tried doing everything I could to stop it
Disabling Google play services from time to time... Using greenify
Freeing up ram ...battery saving mode
Disabling wake up for apps from app ops
Now I use it for 2 hours and it uses 40 percent of the battery with the lowest brightness though
Please give me suggestions or fixes
Thnx

I'm using carbon ROM KitKat 4.4.4 and the ROM is really smooth and great except for this problem that showed up lately
Sometimes when I turn on WiFi it get stuck and totally freeze until I reboot the device
Is there a way to fix this
And I use xposed modules by the way
Could they have an affect ?
I only use greenify, clear recent apps, clipboard and XAD modules
Thnx

Post 3 Default CPU governor settings for this ROM is on demand
Looking at Post 1 & 3 Both of these have to do with the battery Heat
overclocking generates more heat but under-clocking generates less heat (i have not extensively used this feature but asking in the dev forum or if Google'd the governor settings of the ROM might help to see what it does)
high battery temp you less battery capacity e.g 4 amp becomes 3.2 amp BUT low battery temp more battery capacity e.g 4 amp becomes 4.8 amp
also motherboards like to be cool 50 degrees F to 95 degrees F or 10 degrees C to 35 degrees C this is the ideal working temp
anything more or less than that would cause a waste of either performance and/or battery capacity
my tab has worked from 11 degrees through all the way to 60 degrees C battery temp please note i live in South Africa i go to cold places and it gets really hot some times so use these values as only a rough indication
my tabs idle temp is 15 to 25 light work 25 to 35 gaming 35 to 40 degrees C this is a thumb suck of my normal temp can be more or less (just pulled my tab out of my pocket 23 degrees C and while typing this sentence increased to 24 degrees C currently it is 8 degrees C 81% humidity inside a building )
can i ask that you post your battery temp? as temp is relative (i am using antutu benchmark x widget that displays temp and batterylogger)
also the heat could/maybe be causing your WiFi to get suck not on or off
please see it changing the govenor fixes this

Heat, max speed processor = battery drain ?

After reading a lot of battery drain threads on this Samsung Galaxy I9003 subforum i have a doubt:
The recommended solution is to install a clean android 2.3.4 rom?
In my case the phone came with froyo and after a couple of months i decide to upgrade up to 2.3.5... anyway, about one week the phone starts to constantly heat up on stand by mode without 3g or wifi activated and off course the battery starts to drain :S on battery stats i can see the bigger consume (about 62%) is related to stand by mode :S
I try :
battery calibration
factory reset
wipe
reflash 2.3.5
flash 2.3.6
But sadly the problem persist :S
Todayi installed CPU spy and i got a big surprise when i saw the stats of CPU speed, most of the time turns to 1000mhz , like i said the phone it's ond stand by mode with no 3g, wifi connections activated :S
Also i rooted the phone and installed setCPU to limit the max speed up to 300mhz, with that i can see the phone doesnt heat that much (compared when it runs at constantly 1000mhz) but still works at constant 300mhz whatever i do...
I really hope that the solution is to reflash 2.3.4 (or maybe lower?) firmware
Thanks for share all your knowledge and help people like me
If that the case then its an APP. You surely have an app that avoids your phone to go to sleep.
Thanks for your attention and time, i hav running setCPU (at barely 300mhz) and now the CPU temp is always at 32°C also i installed Watchdog lite and doesnt show any program doing an excesive CPU usage :S
Really i have no more ideas of what to look at
Yesterday at night i was reading a lot of drain battery related post (all the threads i found basically) and do the following:
Enter to CWM recovery menu > Advanced > Wipe dalvik
Also i select the ondemand settings for setCPU
Now the phone it's all the time on stable 36°C but sadly my battery still is drained (probably on deep sleep) Most of the time the processor is only at 300mhz and looking the battery stats android system and screen use an average precent (42% for display 23% for android system)
From a full charge (over a powered off phone) after 4 hours the battery has only 40% of ramaining charge and the phone it's on deep sleep (this phone today it's used only for make and receive calls, so no internet connection is activated)
No other people are facing this issue?

Back panel heating

Hello guys,
Guys post your battery temp during normal use,gaming,heavy app use plz..m facing heating issues and want to compare with other Xperia L's
This is during my normal use with 3G which heats upto 40 sometimes
Screenshot attached
Normal Usage using Wifi
Normal usage with wifi:
After playing around 10 minutes of Asphalt 8 on High settings:
The CPU was at 50 degress but it goes to 48 when I took ss.

Mine goes 42 degrees with gaming like FIFA12 etc and in 3G use it stays around 35-40 and with wifi 34-38..are this temperatures normal?

I cannot said what the temperature is when I use 3G as my data package is out for this month already, but I think the temperatures provided by you are normal. Like when you are playing Fifa the CPU is cooler than mine. I think they are normal. Most of modern phone's have heating issue during playing.

Well, don't think so. My phone also heats up during charging when I use it. I'm not sure if this work or not but you of course when you wan't can enable option that Nexus 4 has. It's like when a phone reach certain temperature a cpu/gpu clock is lower to prevent battery overheated.
I don't have it enable as mostly I don't play or do anything more stressful that will make phone hot.

dude you have a fit right...oh you sold it, still that device was about half as powerful okay 1/3 rd yet the battery temp with 0 activity and mostly in deep sleep is at 30 C.
now xperia L is way more powerful so should get a tad bit hotter too right(of course that's based on CPU activity) try it put is down for say two hours no charging , no nothing so that in deep sleep(lowest freq) also no 3g(that has its own daemon that eats cpu power i.e. causes cpu to work and hence battery drain and heat). wifi is okay(stable connection hence minimal cpu usage as no reconnections).
now check yor battery temp should be around 35C so your device is fine.
all this is based on stock heat and power management cant comment on custom kernels.

if you are on a custom kernel the best practice is to uv and NOT oc also change the governor to Interactive since thats far better than performance.(spimply put performance goes to top cpu freq even when not required and slowly scales down while interactive scales up fast and down fast at user touch events) for heating and basic phone wear and tear purposes.
and one of the main reason along with more ram(i mean lower bloat hence more free ram) that i want a cyanogen mod ROM.
Before and after playing candy crush.lol
When charging,it will up to 37-39 degrees
Qualcomm makes the MSM8230 chip that you see in L, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal and Fast (Faster is on Higher end chips like APQ8064). The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. IIRC, there's like only a -50mV difference between Fast and Slow out of the box, however Fast CPUs should be able to handle lower voltages than Slow-type.
This may explain why some people complain higher temp than others on account of same tasks. Although there can be other reasons. I'm not quite sure.
To find out what binned CPU you have, I recommend the following:
YOU MUST BE ROOTED! And installed busybox
1) Install Terminal Emulator
2) Reboot your phone
3) Open Terminal Emulator, and type:
su
dmesg | grep PVS
(if you don't see anything, try it.immediately after fresh reboot)
For example I've fast binned cpu
So basically, far as I understand I got Fast CPU which isn't going to be as hot as the Slow type due to lower voltage ?

then go for ondemand the performance might be a tad bit slower than preformance governor but your battery life should be better along with the heating...also no oc.

Galaxy s6 throttling as hell

Since I bought my gs6 I have noticed the soc temp heat up very quickly and couse a massive throttling of the gpu above all ...so that performances go down of 50% expecially when running antutu ...is that normal or should i send back my phone to warranty
every CPU throttles, the S810 throttles even more, they have to, and don't run benchmarks, they won't do you any good, if in day to day usage the phone heats up it's normal, my S6 do heat up but i never noticed throttling, i never noticed lag when it becomes hot.....try to use your phone normally without ****ty benchmarks...
Thanks for your answer
Yes I know benchmarks are quite worthless ..but it's not just about that..i notice this even while gaming ,browsing and even doing light stuff ..its however pretty much annoying

i don't play games that much, i only play couple of games like boom beach, i don't know if this game considered heavy or light, but if i play it for about half an hour the phone heats up a bit but it doesn't lag at all....in light usage usually it doesn't heat up, but even if it heats up i never notice lag, the phone stutters in some places but no lag.....

Hi,
Please install the app called CPU-Z to check your device temperature. Also keep in mind that depending on where you live, it's easier to heat up than on other regions, as the external temperature does make a difference.
To throttle it needs to get very hot. Check if you have Mobile Data and Location turned on when not needed, and specially Mobile data when you're out of range, they consume lots of power and heats the device up considerably. Also, Wifi if not connected will keep searching for somewhere to connect and consequently will use your device power and heat up.
Another thing to keep an eye on is background apps and the external temperature as mentioned before. On S4 I faced a serious battery drain and overheat problem due to background apps not letting it sleep.
All the best,

Already have cpu z on it
The temps get up to 80 degrees celsius when under really heavy usage ..of course this temp refers to cpu not to battery that stays always around 33 and 37 degrees
P.s i dont notice lag either. .even when performance decrease its good enough..i was only qondering wether it is normal or not
You may have a lemon S6. Return your S6 to Samsung for warranty replacement.

Hi,
80 degrees Celsius seems a bit high to me, like mentioned I'd check with Samsung if this device has a defective thermal dissipation.

Hi,
Here's a screenshot of my device idle:
http://i.imgur.com/rS0VHnR.jpg
And here's one of my device after running AnTuTu benchmark:
http://i.imgur.com/hbNIngV.jpg
I noticed that during the benchmark it got to the 80 degrees range, but it lasted a few seconds, if your device get to 80 degrees and stay at it, maybe it isn't dissipating hear correctly.

OK then there must be a problem with my device....I actually donno what other things could couse this abnormal heat but a production defeat....maybe the weather? ? I live in italy and here is 34 degrees..but i doubt it
Hmmm temp of the device cant be lower than your temp of ambient. Ill post screenshot pf mine after some minutes.i live in kosovo and temp here is aroud 33 today
Here is mine... dont forget bcoze case and screenprotector keeps your phone warmer. I dont use any. I use my phone naked

80 sounds crazy not a bit high
80 its high but device can reach that temp sometimes. Example if you play and fast charge same time it can get that temp. And not to forget outside real temp. Here its so hot... up to 40degrees
Hi All,
80 degrees is not as extremely as you might think. People tend to think its too crazy or high because they never would have seen it and the most times they check their cpu temps on CPU-Z it will be hovering around 40-50 degrees. The best way to check your temps in S6 is to open CPU-Z/AIDA64, have it minimised in a smaller window and drag it to the very corner of one side, while this is running, open a game like dead trigger/skyforce and notice the temps. Also, do the same while performing an antutu test. Yes, the scores will be greatly reduced and the temps will be a tiny bit higher because of this smaller window running simultaneously, but you can compare your temps pretty easily. Also, try to be present in a ambient temp of 26 degrees rather than upwards of 30 for a fair comparison with fellow users. According to me, 80 comes up at times but it lasts only for seconds (S6 starts throttling exactly at 80 and beyond that the core clocks gets aggressive reductions) but it will never be constand even while running a game. Mine CPU idles @35 degrees with ambient temp being 26-30.
My temps : (All temps in Celsius)
Ambient temperature 26 - 30 degrees :
Battery temp : 25-30 degrees
Idle : 32-35 degrees
Slight tasks (Whatsapp, checking notifications) : 37-39 degrees
Multiple applications : 38-43 degrees
Game - hungry shark evolution : 47-52 degrees
Game - Dead Trigger : 55-62 degrees.
Ambient temperature 31-36 degrees :
Battery temp : 33-37 degrees
Idle : 41-44 degrees
Slight tasks (Whatsapp, checking notifications) : 46-50 degrees
Multiple applications : 47-55 degrees
Game - hungry shark evolution : 55 degrees
Game - Dead Trigger : 65-70 degrees.
Also i've noticed that the CPU temps increase for a flash second to 65 above while installing multiple apps from playstore. Try updating/installing multiple apps from playstore, have the CPU-Z open, and exactly while the app finishes downloading and starts installing, there will be sudden spikes in temperatire depending on your ambient conditions. But, never reaches high temps constantly.
all right, thank you all guys for your replies. So..i sent my phone back to samsung and got a new one 2 days ago,i can definitely confirm that the phone heats up exactly like the previous one , maybe just slightly less(i mean 3 degrees..nothing craze).
For anyone suffering of this ''issue", notice that temps may drastically change depending on wheater temperature ,humidity, etc. if weather is at 40 degrees ur phone wont surely get to a lower temp.
BTW it s clear that this phone heats up and throttles ,some may notice that others not, so unless you receive overheating warnings or have other serious stuffs on ur device ,do not exchange it for a new one because certainly it ll be quite the same as the previous one. Oh it 's quite clear as well that folks claiming their device doesn't exceed 60 degrees under heavy usage either are liers or super lucky ones with uber super powerful units...think its more probably the first option.

S4 I9500 Overheating And Heavy Battery Drain

Hello Dear XDA Users, I have been using this phone since it first came out in 2013, I only noticed this problem 2 years ago where the battery drains incredibly fast I have to charge it only 30 min after using it I also noticed that, and just after a 10min use, the area around the camera at the back becomes so hot you can't hold it (exceeds 80 degrees) I've resorted to changing the battery but it just added a new problem which is that the battery percentage when it hits 40% suddenly drops to 0%.
Specs :
Stock TW Rom 4.4.2
Root
De-Bloated
Stock Kernel.
Note: I Use Always A lot of social media apps and wifi is enabled all time.

CPU overheating in some custom roms

hello guys
my xperia z3 has cpu overheating problem in some custom roms. i've checked everything like battery voltage and temperature, cpu temperature and usage.
when i record some 4k videos after 2 minutes cpu reaches over 85 degrees celsius or device reboots while doing it. even while web browsing and watching 720p videos and up, the cpu reaches 75 degrees and up. logcat and last_kmsg aren't helpful to find what exactly causes heat. tried reinstalling the rom several times, wiping cache/dalvik, installing the rom without g-apps or magisk, pulling out simcard and sdcard...
non of those helped me.
these roms are ok without overheating problem:
all stock roms
carbon rom 8.0
lineage os 16
pexorom 1.0.0
these roms have overheating problem:
lineage os 17.1
carbon rom 6.1
the other users of these roms don't have overheating problem. only me!
i've talked to lineage os developer and he said lineage os 16 and 17.1 have same kernel
also carbon 6.1 and 8.0 have same kernel.
now i'm completely frustrated.
note: also the compass sensor died under repair.
guys do you have any idea what is wrong with my phone???
I suggest some steps that help to recover your device from overheating
1.Freeup space on your internal memory and maintain at least 3GB free space on internal storage
2.Remove the tight case that leads to holding the temperature
3.Uninstall rarely used apps
4.Reset your mobile after backup your data
These steps definitely reduce your device temperature

thank you for the advice, but i experience this problem even when one app is installed.
if i install only a camera app after flashing one of those 2 roms and record 4k with it, the device gets too hot.
if i stop doing it, then my phone gets cold. i already tried all of those solutions but they were not helpful.
there's no such problem in stock roms, i can record 4k videos or do heavy tasks for long in them.
The xperia z3 uses the snapdragon 801 , a flagship from almost 7 years ago , that produces a lot of heat and doesnt have the incremental steps on performance that more modern socs have , by this I mean that instead of going from lets say 200mhz doing nothing , then to 700mhz then to 1ghz and so on , it just "boost" into the highest possible clock speed , this makes it snappier but gets hot . With that said , given that you are using a custom rom you could tro regulate this steps with cpu profiles and governors , I think you must have root to use the apps that manage this , but some roms have this controls built in .
You could also try to put it in regular battery saving mode (not the ultra saving mode) this will limit the cpu power draw and may help you if you dont want to do tha manual configuration , turning off gps and sync will help too.
Cheers
