Wonder if anybody has a similar problem.
I use my XDA for work, guessing a lot of people do that, doh! And I work in a warehouse/ outside in UK.
Anyway here goes. By cold temperatures, I mean British weather! Which is in the positive Celcius range, so not that cold..
Last night it happened again. I was out in a field near Hull, working! I made a phone call, then the battery light goes red, 10% battery. In a field how do I charge it!! Simple, stick it in my pocket to warm it up. Within minutes the XDA has 60% again!!
Please any tips or similar experiences. I know that the summer is coming so things look up. But what happens when Autumn comes around again, well my contract is up, so a new phone I do believe!!!! And the XDA will just be a pocket PC, to keep in doors in the warmth.... Maybe a sony...

Cold and batteries
From: http://www.argreenhouse.com/papers/tony2/ECS00_Bond_Untr.pdf:
Tests of low-temperature discharge rate capability of various commercial Li-ion batteries showed that on average only ca. 30 % of battery capacity can be obtained at a C/2 rate at a temperature of -20 Celsius, and less than 10 % at 1C. Batteries described in this work exhibited higher capacity at C/2 at -20 Celsius (Fig. 10) than most of the recent commercially available Li-ion batteries tested. The discharge rate capability of these samples was a strong function of temperature; at a 2C rate, the capacity utilization decreased from ca. 90 % at 21 Celsius to 24 % at 0 Celsius and less than 2 % at -20 Celsius. In the above example, the C/2 capacity was 99, 95 and 37 % at 21, 0 and -20 Celsius, respectively.

(A discharge rate of 1C means "as many Amps as there are AmpHrs in the battery, i.e. theoretically discharging the battery in exactly one hour.)
Polar equipment often has separate battery holders: device out in the open where fingers can touch it, batteries inside insulated clothing with warm human. Tummy or inside of upper leg are warmest...
Thank you
That answers the question then.
Their developing better batteries....
Anybody else have similar experiences though...

Get yourself a battery pack - runs off 4 AA's. (Search ebay under xda). Absolutely invaluable for traveling.

I playing the game Japan Life while using AC charger, the temperature rised up to 61C. Do you know any problem will be affected to my phone?

61 °c! And you were able to still hold it! My phone is hard to touch at even just above 40 degree celcius

61c is insane....... you are lucky not to burn anything inside your s2.
What is the accepted max. temperature?

Well don't say that if you are not sure. 61°C is high, but no way you can say that as insane.
I was reading some articles about Cortex A9 CPU's and found this,
http://www.phytec.com/products/som/Cortex-A9/phyCORE-OMAP4430.html
So the TJ Max of the CPU is 85°C. But for safety you shouldn't let it go above 70-72°C.
But do remember one thing, that is the CPU temp I was talking about, not Battery temp as you mentioned. It's very common that Battery temp will get higher if CPU temp increases.

Yeah, people see battery temperature, but 61 degrees seems pretty high. My battery didn't pass 48 degrees, even when playing complex games. A high temperature will shorten battery lifetime and there has been one report on this forum about plastic inside SII melting down cause of heat, but no info about the temperature that melted it.

Well the battery & CPU, both temperatures are also depending on the ambient temp. It is also advised to mention the ambient temp along with battery temp.
Regards.
Normally mine operates at 42-46. Maybe it's because I live in a tropical country. Once it got to 53 degrees celsius. Got kinda worried, don't know whether to take it back or not. Is this normal?

Hello, I'm bothered by my battery temperature, because it's 39°C and this seems high to me.
What is your battery temperature and what is considered normal?

What is normal depends on what you are doing. What are you doing on the phone when it reaches 39 deg?
if you live in hot climate its around 35 celsius with normal use and up to 42 with heavy gaming.....thats the battery temperature not the cpu ofcourse.

Normal usage, YouTube, browsing. No gaming or something.
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.

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.
*AT&T variat, not rooted but heavily optimized.

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.
