Anyone have a good estimate of what the max safe temperature for the armv6 cpu is? I have setCPU configured to throttle back at 46 degrees, but could that limit be safely set higher?

Curious about this too, I have mine at the default of 50 °C
Sent from my Liberty using XDA Premium App
What I was able to find out in the past was that a mobile phone cpu could safely reach up to 80-90°C. The motherboard and/or components on the motherboard can start to fail around 65-70°C. And for a lithium-ion battery it's best to keep the temp under 50°C for longevity, 60°C is absolutely going to affect battery life. I was never able to find anything specifically on the armv6 or where exactly the temp sensor is on the Aria. I have setCPU configured to throttle back at 46°C, and I have the charging profile throttled back because of the heat generated when charging.
Just remember that the temps being monitored are the battery temps. The aria doesn't have the ability to measure actual cpu temps.

Right, so the CPU could probably take higher, but it's the battery that's the limiting factor.
I think I'll keep the profile as it is now, by the time the battery hits 46 that's hot enough. Don't need my Aria bursting into flames from thermal runaway.

I've noticed a wide difference in battery operating temperatures between different manufacturers. One battery consistently runs at 25 degrees C while another one runs at 38 to 40 degrees C. I'm worried that while using the higher temperature battery that I'm damaging my phone. Should I discontinue using the higher temperature battery?

I find anything over 35C to be uncomfortable, but is that temp what the battery rated for or actually produces? It was my understanding that that was the temp it could safely withstand.

I can tell you from experience that HTC phones will shut themselves off before they can damage the phone or the battery. The battery has a much lower temperature range of operation than just about anything else. IC are virtually untouched by heat below 90c. At that point, the mode of failure tends to be a degradation in the doped silicon that the transistors are made off, and it usually happens over time, not instantaneously.
Thank you!
Thank you for your very informative reply!
My device is overheating over 40 degrees. How i fix it? This heating up 10 minute in bottom backcover
40 degrees on cpu or on cover? if its on cpu youre perfectly fine

i don't know. its heating bottom in screen and backcover
How do you know its 40? have you checked it with thermometer? if its heating so much i'd advice you check whats using your cpu because something is putting too much strain on it. and if you are rooted consider undervolting. For few minutes of adjusting voltage you can go down even 8 degrees

Kernel Toolkit i see cpu is 40-60°C and battery is 43°C while playing or browser internet
60c is nothing to worry about as most cpu's will switch themselves off at around 85-90c. 43c average while gaming is not a bad temperature. I wouldn't worry about it myself.
The lower scored benchmark is at from idle of around 40C (CPU temp) while the phone is in the room. The higher scored is when I placed my phone in the freezer and let it cool down to around 28C (CPU temp).
Why is the phone so hot even at idle? Do you r phones go as high? What are your ambient temperatures? I'm in a tropical country and it is around 29C here right now.
The battery temp is only a degree or two lower than the CPU. It's terrible for the battery to be at this temperature.
Mine is around 36 C after 30 min of browsing . inside room temp is around 22 C.
Yeah, Mine also get so hot like 40 -45 like your after 20min of used.
But our Poco got cooling system right, then why like that?
My previous Moto z play was not like that ?, It was only heat while charging because of rapid charge.
It's coz of that garbage of IU called MiUI. Every update it screwed something.

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 Samsung Galaxy Note 10+ 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!

The heat pipe system in it works very well... this phone should never run hot. If it does, something is wrong.
Mine needed extensive optimization to run cool... it's my favorite phone now. Like having a laptop in my palm. Avoid "upgrading" to Q, it's a nightmare.

All phones with good cpu/gpu get hot when gaming for long time.
There is not any thing wrong with that.
Exynos phones get very hot ingame, cpu temp can go up to 70c.
If your note 10 don't get warm after 1h asphalt 8 there is something wrong with it like low fps and or trottle.
Batteri temp in heavy game around 40c
Cpu temp in heavy game (Exynos chip) 60c-70c.
Your phone will be warm..

Talking about unwarranted running hot. dah.
The hottest my phone has reached playing games was 45°c. But it mostly sits at 43°c when gaming. Is that good?

No.
107 F is too hot*. This isn't a desktop cpu; running an LI battery this hot will greatly diminish its lifespan.
Some of the CPU heat plus the extra current drain heat the LI bat up. I never let my battery temp exceed 103 F when in use or 100 F during a charge. >85 during charging is better.
Put a damp rag around it or on the backside if in use to cool it if the ambient temp is too high...
*43 C is fine for CPU temp as long as the battery isn't getting baked. F is easier for real world temp measurement.
My cpu and chips are running at about 104 F while the battery is at 95F; the ambient temp is about 90 F, acceptable.
This with a light cpu load with brightness at about 40%
For heavy cpu usage at these temps for more than 10 minutes would drive the battery temp unexceptably high without external cooling.
Monitor the battery temp. Lol, if the phone feels very warm/hot it's damp rag or shutdown time.
F is easier for"real world" ? F are only used in ONE country! Which, by no means equals ALL the world, science, real science uses metric system

The Fahrenheit scale is centered around the temperature zone most used by humans.
A 10° F isn't too much a of a change but modest amount.
A 10° C change is huge.
It's ackward to use in real life... suffer.

Good thing you don't have the Exynos version.
The idle cpu temp is around 50c with about 20-25c room temp.
What program to you monitor cpu and chips with?

122 F is really hot for a cell phone... a very expensive hand warmer. When a phone feels hot; it's already too hot. This will greatly shorten LI life especially if above a 90% charge.
Current drain* at idle with 50% brightness level should be below 220 ma. Typical idle current on this one averages at 140-200 ma.
If it's running >400 ma, something's running in the background sucking the life out of it.
I use different temp apps. Been playing with the Gitlab one.
It's 26.6C (80 F) ambient temp here and the CPU is averaging about 35.5 C (96 F) as I'm using the Note.
Battery temp is the only one I need to really watch.
I monitor that and battery current drain.

exynos is running hot, there is not mutch you can do.
Here is one example
https://m.youtube.com/watch?v=LfZUNL5hyVw
If you pause the video when he start antutu you can se the cpu temp of the s20 ultra (about 56c without any massive load).
My old s8 with exynos got warm and it worked just fine for 2 years, sure i lost a few % on the batteri.
After 2 years just get a new batteri and enjoy.
I know snappdragon is running mutch cooler, but make sure you get a app that show the right temp. 35c in a 26.6C room sounds like idle temp at best.

For you Fahrenheit may sound "logical" as you grew up with it. For us - the rest of the world - we grew up with Celsius. We don't need a scale "centered around a temp zone used by humans", we know what effect a 10°C drop in temperature has on us...nothing ackward about it.

Unlike the metric system of temperature measurement it is uniquely centered in a range where most living occurs... 96.8° is a better way to index human body temp. One degree matters.

Update...
Trying out this temp apk:
https://play.google.com/store/apps/details?id=com.novelmatrix.temperaturemonitor
It will display in the corner of the screen real time. Low resource usage. Some ads on set up but liking it so far.
At 96° ambient I'm seeing the CPU, GPU typically going between 102-118 F depending on usage.
Browsing it's running between 100-102 F
Internet vid jumps to about 114 F at this ambient temp.
Obviously higher for cpu/gpu intense apks, haven't benchmark it yet with this running.
The battery is at 96.8 F and typically runs cooler.
The heat pipe seem to work well; dissipates heat rapidly from the cpu and helps keep the battery temp down.
