Hello to all of xda-dev users. I got problem with my Galaxy s6 Active smartphone. One day it's just start overheating and draining batery very fast, just about 1% per minute or two. I have search many threads over many forums for solution and didn:t find it so i ask here, maybe someone will help me.
What i have noticed that overheating is caused by processor (sensor exynos-therm) while battery stay cool. I have did a factory reset few tmes but it didn't help. I have flash a new rom from this forum, upgrading from android 6.0 to 7.0 but it also didn't resolve the problem. I have no ideas what to do and where to search to find reason of overheating. While device is running, all monitoring software shows minimal activity and processor usage, anyway the processor seems to overheat up to 80C (almost 180F). Please don't say it is normal cause it didn't work that way before that malfunction. I hope someone will help, thanks!
To start...
Run the monitoring software as root? Reading the CPU usage of processes might be restricted without it?
CPU clock is lower with thermal throttling and doesn't look like heavy usage?
GPU?
Persists with wifi off?
Check for wakelocks/CPU background time, and it's the process at the top?
*#0011# > select SIM > Tx power/TX, when the signal strength or quality is low, the decoding/transmitting could be expensive, the tx power isn't everything but it should ramp similarly, is this high?

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?
why isnt the company doing something about the overheating issue? is there any solution for this? Just bought my one plus one and this overheating issue is such a let down.
From what I can see the reason the charger "overheats" is because of the speed in which it charges the phone. A way to fix this is to root the phone and install an app that can slow down the amount of power the phone takes in during charging. Ofcourse this means longer charging times but it will help with the heat issue.
With regards to the phone, unlock the developer options and underclock the phone. Obvious advantage of longer battery life and less heat but with the trade off of performance. I would reccomend only underclocking it a little but as you will get lag because of the restricting of power to the CPU. Changing the cpu governer etc. to save battery will help with heat as they just slow down the ram and CPU.
My appologies if you have done all of these and are still experiencing these issue, i do know where you are coming from but they are trivial issues and depend on how you as the user do use the phone. Have a browse around forums etc. to find tips on slowing things down a little and things will cool down for your phone.
I hope i have helped even a little bit
How do you define overheating on the phone? What temperature?

No overheating here. What do you mean? The phone gets hot and turns off?
overheating

This phone is not known for overheating any more than any other phone that will heat up when driven to its max for example in heavy 3D gaming. There is a difference between heating up and overheating
First, run stock without any extra installed apps, and NO running apps or network connections or anything and see if it's overheating.
Do not use an aftermarket charger--they could be rated for different amps and overheat or damage themselves or the battery.
Phone brand new?--simple--ask OnePlus to replace it.
Phone used?--probably been abused--get your money back and get another one.

This. Far too many people mistake a device heating up for a device overheating. All phones heat up, they have no active cooling. If the phone was actually overheating the thermal cutoff would kick in and the phone would shut down.

No overheating issue here, you may want to try different - weaker charger like stock Samsung or Sony one with output current ~700mA-1A and see how it performs.

Starting a month and half ago my LG Nexus 5 would get hot near the camera (Where the CPU is) and drain the battery unusually fast, even without an active app opened, now I can not keep it on outside because of the drain and even if it stays connected to a charger, it slowly builds a charge because of the drain.
I recently changed the battery and the problem continues to persist.
This started happening around when I went over all the settings in the phone and apps, I fear I might of turned on something that is causing it in the background but I can not figure out the exact problem.
Please help.

Check the frequencies of the cpu, sometimes the minimum value gets stuck to a higher than needed frequency.
You can do so by using Kernel Auditor (root) or CPU-Z. Obviously if they're higher you'll need to set them lower, 300 MHz is the normal minimum freq. If that is not the case then install Gsam Battery Monitor and enable extra stats, you should be able to figure something out with that one app.

thank you, it was the outlook app going rouge
I have a problem with my Samsung Galaxy S5 G900F, running the official Android 6 marshmallow update.
Sometimes when I try to take a picture with flash, it tells my that my cpu is too hot and it needs to cool down, before I could use the flash again. I downloaded an app to look at the temperatures, and after not using the phone for a while I made sure it was cold and the battery showed about 29c, but the cpu temp was about 50c. I don’t think this is the actual temperature, because every spot of the phone was absolutely cold. When I ran some slight tasks the cpu temp was rising to about 86c. The phone was indeed hot tot he touch and the battery temp was rising too, about 40c, but I still think the temperatures it is showing for the cpu are not right. That’s why I get some errors like that. The battery temp seems a bit high too.
Now my question is, is there a way to fix this? Is there a way to maybe calibrate the cpu temperature sensor? I tried everything, all the way up to resetting my phone to factory settings, but with no luck.
I also noticed that the download speeds are very slow, especially when I try to update or download an app from the play store, compared to other devices on the same network. I ran a speedtest and the results are normal, the same as other devices, but the real world download speed isn’t.
I hope someone could help me with this problems. The slow downloading speed isn’t really bothering me that much, but the inaccurate cpu temperature is. Sometimes it gets really hot, sometimes even with slight tasks yes, maybe that isn’t normal too.
Dears,
as sometimes might happen, my Galaxy S20 is draining battery.
With many tools I can see CPU is always around 60%, also when it should be idle.
How can I check what process/app/service is hurting CPU?
Regards
