Hey all.
Just wondering what is the standard battery temperature for the myTouch 3G. I am a little concerned that my battery is reaching temperatures of 36 degrees celsius when the phone is charging. The back of the phone is really warm when I touch it while it charges. I'm worried that the heat will mess up the phone.
So what temperatures have you all noticed in your battery info?

I picked up a wireless charger for my Nexus 4 from here gadgets4geeks.com.au/product/qi_wireless_charger
The problem is that the phone reaches 130 degrees fahrenheit (54 celsius) and stops charging (due to the overheat cutout) before the phone is fully charged.
Once it stops charging, it cools down a little, then starts charging again before it overheats again. This results in the battery level remaining around the same level. It is also annoying at night, as every time it starts charging, the screen turns on (unless I turn on a daydream).
I use a TPU case and it's summer here.
Anyone else have this problem? Any thoughts on how to keep it cool to achieve a full charge? I was thinking about raising the phone above the charger or something like that?
Thanks.
Here are some screenshots of it charging then stopping when it got too hot:

In the word, no. Mine never gets much beyond 37°C using the LG charger, but it is Winter here and I never heat the house above 68°F.
i was on latest RR rom cm. after charging my phone for 30min it was too hot and even i opened back case and battery removed then i inhaled it was some plastic burn like smell. though its working without an issue. im bit nervous why it happened and is this smell normal.
Not sure if the CM ROMs have fast charging?
If fast charging is enabled it will charge the battery much faster, but also cause it to heat up more. The smell is a side effect of heating up plastic.
I'm sure Samsung tested that it's all safe.
But it was bothering me also that it got that hot so I just disabled the Fast charging (Settings->Power Saving).
It takes a bit more time to charge - I'm usually not in a hurry to charge it, it will still charge in 3-4 hours max. But it will not get that hot and it might also be easier on the battery so it lasts longer before needing to be replaced.
I was trying to turn on my phone yesterday while I was skiing and noticed that it couldn't go past the boot logo. Later, I turned on the phone when I was in the car about half an hour later. I did some research and I wasn't the only one that this was happening to: https://forums.oneplus.net/threads/...t-is-the-operating-temperature-of-op2.421117/
But I tried looking online for any reference of operating temperatures and couldn't find any.
I live in Canada so I do experience some cold, not a lot just some. Room temperature is 23degrees therefore battery is around 23-26degrees idle.
CPU and GPU temps are around 33-36degrees. When I go outside usually the phone is in my pocket. The battery temperature can drop to 15 or sometimes even 10 (playing Pokemon go in the snow!) but never below 10. Lithium-ion batteries can go down 0degrees but I guess at that point the phone would stop working.
Its always good to keep a spare cover with you. Lithium-ion chemistry works best in room temperature when charged/discharged
(read here for more information http://batteryuniversity.com/learn/article/discharging_at_high_and_low_temperatures).
To keep/mimic this room temperature keep your phone in a case preferably a rubber case so that there is some heat (not too much just some) when you are skiing.
I hope that answers your question. The phone has about 5 (or more idk?) temperature sensors or thermisistors (bascially electrical resistors that change resistance with change in temperature). Your phone turned off as a security measure to make sure your battery is protected. As the article suggests operating a lower temperature can cause permanent battery degradation. Its the same reason Tesla owners see a slight decrease in mileage when operating the car in sub-zero ontario, canada weather. I guess thats a topic for another day
Wow. That is the most detailed post I've ever seen in a help thread. But I should note that I do that a case on my phone (Tudia) and it still happens. My relatives have a OPO and they seem to be okay in the cold temps
I went skiing yesterday and charged my phone in the cold with a battery bank to 80% cap since its rooted. I went to go warm up and checked my phone after it warmed up from the cold and it was at 97%. I wish i had the thought to screenshot, i thought it was something that i would have found a post on the internet by now and never bothered, nothing about it on the internet.
I have a gopro i ski with also and lithium ion batteries suck in the cold, they dont produce a strong charge and can seem dead if temps get too low. warm them up a bit and then they are alive again producing charge since the internals are at optimal temps. I frequently rotate a couple of batteries after they freeze. My theory is that my phone was cold, the battery was producing charge but a weak one in the cold so when the phone thought it was at 80% it really was a weak 100 charge but when the phone warmed up, since it wasnt charging and whatever stops it from charging beyond 80 couldnt stop it because there was no current to stop and it reported its true percentage. I'm positive I saw it at 97 and i've never done any fixes or mods to change the 80 problem so Im going to try and reproduce it again.
I have left my phone outside (-12°C/10°F) for 15 minutes and when I took it back, screen was "lagging" and it showed battery temperature = 0°C/32°F. I've turned out off for 5 minutes and warmed up to 8°C - screen was fine. In next 10 minutes battery reached 19°C.
Tell me, could I damage anything?

You should be safe, li-ion batteries can handle below zero temperatures, they just have trouble charging when too cold. Heat is generally a bigger issue than cold, as it degrades the batteries by speeding up the chemical process inside. The cold slows it down, basically preserving the battery.
As for other components, they should be fine too.
