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

Hello,
Exact same problem here.
I'm running latest LineageOS official.
What app are you using ? I can't find that one called "little" on the play store...

Thx, well it's not exactly the same problem as you have since my CPUs are running in low power state when the phone is not used.
Anyway, when I start browsing the internet, the phone gets hot and when I'm playing games, it just gets super-hot. (not in charge while using it btw).
Previously, I had a Nexus 4 which is famous for its overheating problems, but the S7 is worse.
This, the ill placed speaker, the poor quality of the AMOLED, I'm so disappointment with this phone.

The AMOLED screen on the S7 was widely regarded as the best screen on a mobile phone when it was introduced.
You're running an unofficial ROM + kernel and running into problems and are blaming the phone? Lots of people seem to hold LineageOS up as the solution to all problems, but on many devices it seems to be a giant hack.
This screen is a piece of **** (mura effect & spots when lowering the brightness), my Nexus 4 screen is at least 10X better.
I'm running Cyanogenmod/LineageOS since the very beginning, never had this kind of problem before...
The S7 Exynos phones do tend to get a bit warm if you're browsing certain websites, Facebook and streaming, and it'll get hot if you're playing resource intensive games like GTA & Bully. That's what happens when your device's CPUs can reach a max clock speed of 2704MHz. Take a look at what apps are running in the background first.
I'm only able to read the battery temp sensor, no other sensor available despite having tried a lot of monitoring apps.
Idle temp : around 29-33°C
Heavy use : up to 45°C
Past 39°C, the phone gets really uncomfortable to use.
I did further testing with another S7 (carrier firmware, brand new), launched a stress-test app on both phones at the same time and after 15 min, mine is 4°C hotter (battery temp). It's not really relevant, maybe due to my tempered glass preventing heat dissipation or some LineageOS optimizations, I don't know. Anyway, the S7 feels way hotter than my previous phones.
it's strange that power user/advanced user have to complaining about overheating and comparing with other brand when they are running unofficial software and kernel. and i think the word 'overheating' is about the cpu/chipset not the battery. *correct me*

Yes but I only have access to the battery sensor. The frame is hot on both phone tough.
i have a snapdragon version of S7 and i don't think exynos version have overheating problem running on official firmware. running Oreo right now and still don't have such problem. and FYI using the phone INFO apps (google playstore), i can see the temperature of the cpu.
So i have 8/256 zenfone on last android 10 update but multitasking on this phone behave strange random apps are getting killed in the background even if I use idk 50 % of ram and by night most of the apps are gone from memory.
https://zentalk.asus.com/en/discussion/comment/37973#Comment_37973 now some assus boy is trying to say that this is fine but no it is not -.- iam wondering if iam missing some option to turn off or any of you have some similar issues? Maybe iam missing some power saving option to turn off but i think i turn off all of them by now? :crying::cyclops:
Yes, by default this phone has fairly aggressive memory management. Most of the settings you'll want to adjust are under Settings - Battery - Powermaster - Battery Saving Options. You might also want to have a look under Settings - Advanced - Optiflex.

Think I check them all already but today have the same situation still. I even do the format yesterday and for half of the day, phone keep 24 apps in memory without reloading and overnight on charger phone just clean its memory and leave me to 3 apps open so it cleans 21 apps -.- 'm on the edge of returning it i pay 25 % more for 8 GB and my phone is pretending to be 1 GB device sometimes...

Even my older phones from Xiaomi and Xiaomi is widely known for aggressive ram management never went full retard on cleaning almost all my apps. :silly:
And why on earth it decides to save battery when its plugged to charger xD.
@berni502 is right. There's a bug with LMK or something. You can use RAM memory filler to test how much ram can be allocated to an app (and it gets killed at 5GB instead of 7GB on Pie). Since then everything gets killed even though there's about 4.5GB free, SystemUI included. Reboot fixes the problem. I think I'll open a new discussion there.

Pls do it! I feel like I am only one in there who cares : ( it seems that killing apps overnight and a way too aggressive ram management starts on android from android 9 there is a lot of ppl writing about it on pixel,oneplus and samsung forums but on asus is it just me : /.
I even find this site but think op resolve problem already because i have op 7t for +/- 3 days and it just works fine no even single app missing form ram overnight.
https://dontkillmyapp.com
I actually can semi confirm your observation about ram after reboots. Yesterday on clean install android 9 multitasking gets huge temporary improvement ram can get as low as 1,5 gb ram or even less but after a day 1 + unwanted ram clear overnight and my restart after this phone struggle to pass 2,8GB free memory it can handle way fewer apps in memory and start reloads them sooner.
First day on android 9 downgrade
VS
Second day
It can be fixed oneplus show it but they won't fix it if I am the only one who is barking about it on their forum.
BTW does your app getting wipe out from memory overnight? I mean from 20 + app get something between 3-9 in the morning and if not can you describe what exactly do you turn on or off in your system or you just don't touch anything?
Well, I'm not that hard multitasker. Of course I have some background services enabled but it's far from having 20 apps running at the same time. Regardless, after a week or so without reboot some issues become more apparent and LMK seems to be very aggressive even though there are 3 GB left (not even buffered).

I must confirm that you are not alone. I did it exactly as you described in one of your posts. Before going to bed I opened 24 applications, then I went through them all once again that they are really all loaded in memory (I have 6 GB of memory). When I woke up in the morning and pressed the multitask button, I was surprised to find that out of the 24 applications, there were exactly 3 left, as you have repeatedly claimed.
I stared at it open-mouthed. In fact, I've never done this check because the phone is fast enough that I just didn't recognize in the morning ((still sleepy) that applications were loading from Flash Memory instead of RAM.
This check is really simple, anyone can do it, but apparently not many users have done it yet.
Next time I would like to try to find out which applications actually stayed, whether the last used ones or completely random ones, and what processes took place at night that might be blame.

I am really tired now of talking to the Asus boys on their forum its is like talking to the wall. Now i get info from them that this is a normal android 10 case but don't believe in this... I use logcat app for 2 nights but I am not that smart to figure out what and where its happening am trying but I think it will be better to return this phone while i still can... : / in the end like i said i pay almost 100$ more for 8gb to have those extra multitasking abilities but they are ripped off form the phone.
From my observation apps stayed in ram can be different. It sad because that ram issue was reported in July on their forum now i don't have any hope in asus work on fixing this problem.
use ram truth or some app to monitor ram and you see some another strange thing even that after night you stay with 3 apps open your ram will be almost full. For me, it was today about 700 mb difference after overnight app kill.
Have you guys tried the same exercise of opening 24 apps and checked them back at morning with other phones?. I'm no expert, but it is my understanding that apart from the LMK that kills apps if memory is needed there is also a time killer i.e. if an app is not used after X amount of time it is killed from memory, so what you see is normal Android behavior.

I haven't had a reason to deal with this issue yet, but after a while searching, I'm starting to feel that this is a feature of Android 9 and 10 that users of various brands complain about:

Even if android 10 works like that so what? xD they modified many apps in zenfone system and change many options and not implement many aswell so what's wrong with fixing something that clearly works bad and it is no fitted at all for devices with 6,8 gb of ram and more(not even 4 i will still be mad it this happened to me on 4 gb xD)... hmmm, now I'm curious how it works on rog phone 2 this beast have like what 12 gb of ram ?

On the contrary, it is important that the links are older, because it only proves that this problem has been around for a long time (at least from A9) and in addition to different brands. The first link is from October 2019, which I would consider as current enough.

yes but they are speaking about anbdroid 9 and they even find some semi solution of that in there(that restart one it shows how bugged it was) ; ) we don't know how it is on samsung android 10 now.
On pixel 4 seems to be ok without any issue and i can't find any no outdated info about oneplus so i just assume that there is no longer a killing app problemo + i have one fr 3 days.
Even minus app killing overnight ram management on asus it's just strange at the moment I am reopening one app that should be easy in memory because i have like 3gb of free ram left but nope it's gone -.-.

Question is, why would you want an app that you have not used for X hours to stay in memory? All apps that need to run in the background use a service for that purpose. The rest gets killed as they should because either another app needs the memory or because is haven't been used in a long time. To my knowledge Android has been like that for ever (as opposed to windows for example, where you can completely stall without memory unless you manually kill things).

And why do i want all of them gone overnight when I am connected to charger ? Solution is easy if you wanna save your battery you have power profiles for that so you can and if you don't wanna do that you should still be able to but you cant... and there is matter of price why do i pay so much for so powerfull device when iam force to not use its hardware to full of its capabilities. You are right about android ram menagment but that i wanna kill your all apps start on android 9 apparently. There is nothing bad with cleaning some space when you need that for new apps but killing it all or killing it when you have half of ram empty its just stupid...
you can read some more in here maybe https://dontkillmyapp.com
and imagine i have 8 gb of ram that rog phone 2 can have even 12 and 6k battery if they have same problems lol its is like buying a sports hybrid car with turbo v8 engine and be forced to use only that electric motor because of fuel savings ^^
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
Hello XDA ! I have problem with my Note 20 Ultra Exynos... When I bought it, started lagging immediately, I brought it to authorized service center and they told me that device is working correctly and it has no problems. But now when I am doing something e.g using Samsung browser, or watching videos it starts freezing and random reboots. So I tried wiping cache, factory/Odin reset but no results, I am not using many 3rd party apps. What do you think ? What is the problem ? Or can you tell me how to know if CPU or GPU is faulty ? Using normal mode FHD+ and 60Hz... I'll attach drive link How it is lagging
I have the exact same problem
While the device get warm it's starts laging and freezing,
And Samsung said me too the device working correctly,
I have 2 friends who got the same device and doesn't have those problems.
This is my last Samsung device for me.
Horrible customer service .
It's an app that's probably sucking up bandwidth, CPU cycles and battery.
Google Play Services, Backup Transport, Framework and all cloud/chat apps are prime suspects.
A random reboot isn't normal though. Android 11 is a mess. Try running factory loads for the Google system apps, Gmail and Gmaps. Kill Google firebase, all feedback and all cloud crap.
The exynos chip has basically zero cooling. (No joke, look at a teardown vid of it).
It's way too much CPU for way too little heat sink.
It can throttle itself (like all chips will) but can definitely crash under heavy load and heat if it's a poorly binned chip.

It's up in the air which cooling solution Samsung used short of doing a teardown of that individual phone. Samsung isn't consistent with the internal parts used during even a single production run... a long running issue with Sammy. Most noticeable with the smaller chipsets and components that can cause a firmware update to skew some of the "same" models... until Samsung includes the inadvertent variants in the update.
You know it's bad when Samsung physically has to examine the phone to know what chipsets were used (excluding the processor,etc).

It drives me crazy, warms up for no reason and lags af, sometimes I put it in the fridge to cool down :d

There's a reason it's running warm; excessive cpu cycles and/or excessive internet usage.
Find the apks responsible.
It's also toasting your battery*... been there, done that, and yes it's maddening until you sort it out.
This probably needlessly cost me at least 200 maybe a 1000 full charge cycles on my old Li battery
*charge battery no more than 80% to help limit the high current drain damage until the issues are resolved. Be especially careful in high ambient temperatures as you can do permanent damage to it quickly.

Thanks for tips, I had S20 Ultra before, but it was working perfectly no lags no reboots, they have same exy chips right ? The hell is going with this one ? I am very very disappointed with N20U, right now CPU temp is 26C, not every time/everyday starts warming and lagging, I can't tell what is causing heating because, I am doing same [email protected] everyday, scrolling reddit, listening to music etc. Sorry for my English if it is grammatically correct...

Your english is fine. Not sure about chipsets, it should be a great phone though once you work this out. I'm thinking about getting either this or another 10+.
I have the Note 10+ and it was a hot running power hog too. At first it was ok but within a few days it went to hell.
What I learned...
Do not enable any power saving in Device Care ie the toggle on stuff, enable fast charging only. Do not optimize any apps in the settings options.
Android can manage its self well without that junk.
Developer options>Standby apps, all buckets should show as active, if not power management is active! If active it will cause erratic behavior as well. Blocking background and data usage is generally ok to to do though.
Use Package Disaler to help tame it.
Home - Package Disabler
The only NON-root solution that let’s you disable any unwanted packages that come pre-installed / installed with your phone / tablet.
www.packagedisabler.com
Use Kara Firewall (Playstore) to lock down the internet. It's logging feature doesn't work on Q and above though I believe. I'm running on Pie.
If you did any major firmware updates do a factory reset now. Otherwise clearing the system cache can help.
Try rolling back apks especially system and Google apks to their factory loads or updating them. Updating them sometimes makes them worse.
Clearing the system logs as needed with a 3rd party cleaner can help.
Disable all Google, Samsung and carrier feedback. Disable Goggle Firebase.
Disable all cloud, WhatsApp, FB etc. crap.
Goggle Play Services*, Backup Transport and Framework are prime offenders, clear data as needed. Package block them too and well as Playstore when not needed.
You can also firewall block Play Services* UID 10O44, Android Services UID 1000 and Gmaps*.
I use Galaxy Labs Battery Tracker, it's helpful in spotting Goggle Framework usage. Framework will always show as running even if PBed but it's usage should drop drastically.
Play with it, adjust by trial and error.
My 10+ is now a heavily optimized stock load, cool running machine that runs very well, fast and stable. It wasn't always like this though.
Once you get it optimized avoid firmware updates especially if it's running well as they can throw you straight back into the hurt locker.
*toggle on as needed. PD MDM let's you set a widget to toggle box checked apps on/off. It works great.

Thank you again for all these tips, I'll try them !
But I have two more question if you know, my device only charges at super fast charging, when I enable fast charging it says cable charging, using stock charger and USB cable what is this ? This charger only charges super fast ? and the second question is why enable fast charging ? I always charge at regular charge...

It only fast charges if it's enable and has a fast charging compatible brick/cable.
It should say fast charging when plugged in if it is. If not try toggling the switch 3 times*.
It will charge at normal speed otherwise.
Fast charging will likely decrease the battery longevity at least slightly.
Li's love frequently midrange 40-70% partial charge cycles. It takes only 10 minutes for a 20% charge in this range. It's fast.
* failure to engage or erratic fast charging can indicate a battery failure...so I learned recently
If battery swelling is spotted replace it asap.
It will push the back panel up if it swells.
Hi guys,
I bought a used Note 20 Ultra Sanpdragon version at a very very advantageous price, yet to arrive, but the one who sold it to me says he has only one "problem", the phone restarts randomly.
What could be the cause?

Problem is hardware bro,maybe is better buy new phone then with low price. Sorry.
I have this phone when launched, never restart randomly.

Thanks bro, the phone is in warranty, but I live in Italy and the phone is imported. He has no time to resolve the issue that's the reason of the sell. I hope is however service in crash, something resolvable via software.
Sorry for my English.
I would boot your devices into Safe and see if the same issue is present. If it is not, then it is definately an app, which is causing the issue. I would start by uninstalling apps from your device, starting from the most recently ones, which you have installed.

It may be the battery if you're lucky.
Start there.
If the battery is good, factory reset*, if still doing it firmware reflash**.
If that doesn't get it, it may be a blown mobo.
Probably your best bet is to have a tech with a lot of Samsung experience look at it.
*leave all system apks running in their factory load versions. Add no 3rd party apps until you can ascertain it's running stable. If so add 3rd party apps. Then only update system apps if needed and one at a time.
**may have corrupted firmware. Usually a hardware failure causes this but not always.
You can skip the factory reload and go directly to this step if you want. Load its original stock Android 10 rom for now.
