Hi all,
I'm traveling today to a pretty hot place where the temperature can get to 55-55 degrees Celsius. I wanted to know If any one knows of any temperature limit, that if crossed may damage the screen to the electronics of the phone?
Thanks
I think the battery has a maximum operational temperature, and that the instructional booklet specifies what. Additionaly, this one time, at JPK, I was playing rescource-hard games while listening to music, and the phone turned off. I think it was around 55 degrees celcius. But check the booklet!

i've hit 61c and still working fine
others have reported 65c

Does he mean room temperature or operating temperature though? If the ambient temperature is 55 deg C, then the phone itself will reach MUCH higher temperatures than an environment of 20deg C (because dissipation of heat becomes increasingly difficult).
Check the manual to see the tested ambient/environment operating temperature range. I doubt many manufacturers test beyond a 40 deg environment/ambient temperature honestly, because humans need to maintain a core body temperature of 37deg C anyway, but the maximum operating temperature of the internal components probably isn't known.
If you must operate your phone in a very hot climate, I'd suggest you only use your phone when absolutely required, and disable features such as bluetooth/wifi to keep it cool. But if it were me, I'd get a militarised phone..
If you are referring to the phones internal temperature (and the outside air temperature is much cooler), then 55 deg C is most likely fine. Solder's melting point is far above 100, and the Pentium 3 at least was shut down at 100deg C.
First of all let me apologise if this issue has been mentioned before. Just got my One last week.
I have noticed that when tethering as a Wifi Hotspot, while being plugged into the mains to keep charge, the battery temperature is being reported as around 51 degrees celsius by the app "Battery Monitor Widget", at which point the app notifies me that the battery health is no longer "good" but now "overheat".
I use tethering frequently and have been doing so without any issues on my Nexus 4 before I came to the One.
Should I be concerned by the temperature? Surely this will decrease the life of my battery/phone?
Many thanks in advance.
EDIT: I think this should be in the One Q&A, Help & Troubleshooting forum. Please move it if so.

The phone will get warm whilst charging and if it's working at the same time will get warmer.
When tethering leave it off charge and you should be ok.
Thanks for the quick response. Tethering seem to be pretty demanding on battery life though.
When tethering and charging at the same time the mA charge shows as 0 - as in the charge from the main is equalling the usage.
With the screen off and just tethering without being plugged in the drain is between -1400 and -1800 mA !!!! Battery goes flat in no time at all
Should it be that high bearing in mind that the screen isn't even on?
Thanks
I've read in another thread here on xda (I can't remember which) a response email from a tech representative regarding battery temperature. The guy said that as long as the battery temperature is below 55 degrees Celsius the battery will be just fine.

That's reassuring to know. It's just very worrying when you reach for your phone and it's like touching the sun :laugh: Keep checking to make sure my fingertips are still there or if they've been burnt off
I understand that the case acts like a massive heatsink due it's aluminum body. I use tethering as my primary internet source so I just hope keep at 50 degrees for most of the day doesn't reduce the product life too much
Just wanted to let you know that 50 degrees Celsius isn't something to be terribly concerned with when it comes to computer parts in general. Unusually hot? Yes. Technically, a hotter-running computer (or in this case, smartphone) is not as likely to live as long, but it's a negligible effect so long as it isn't 50+ degrees Celsius 24/7.
For reference, Intel's Sandy Bridge processor architecture is rated safe up to 83 degrees Celcius.
How about this? 65 degrees for a while!
Have a look at the middle of the screenshot.

An hour of temperatures above 55 degrees Celsius with a peak temperature of 65 degrees Celsius is very stressful in my book. I have Gsam Battery Monitor installed and I've set it to notify me every time the temperature goes above 55 (that happened only once to me for a few minutes). The cause why the phone's battery gets very hot is because I'm holding the phone in direct sunlight or/and I'm in a very hot environment or/and I'm doing some demanding tasks (play a game or/and browsing internet with 3G/4G on) . The solution to cooling it is to get out of the sun or/and the very hot environment or/and not to use it for a few minutes (because the aluminium case acts like a heatsink the phone cools very fast).

I would avoid that situation again if I were you.... you are at real risk of damage.

I bought a xiaomi mi 9 phone a few days ago, I found on the internet that the battery in the phone should reach low temperatures. I would like you to check if they are normal.
When playing not only demanding games, the battery quickly reaches a temperature of about 38 degrees Celsius.
During normal internet browsing, the battery reaches about 36 degrees.
While watching Youtube the battery reaches 33 degrees.
Sometimes these temperatures are lower. I care about the assessment because I want to finally take care of the phone. Thank you for your help and sorry for poor english.
If you want our opinions on whether those temperatures are acceptable or not, you have to also share the ambient temperature.
38 C should be normal for 23-24C ambient, don't be fooled by some supposedly "light" games that are badly optimized and eat the battery alive causing heating, just because a game is 2D doesn't mean it consumes less battery.
36 C for "normal internet browsing" seems too much, I get way less at 23-24 ambient, not more than 30 C.
33 C for youtube is fine especially if the videos are bright with sound turned on.
The ambient temperature is about 22-23 degrees, maybe a little more. Unfortunately I don't have a thermometer inside the house. Now while browsing the internet, the temperature was between 31.5-32 degrees.
Usually the screen brightness is set to half the bar or slightly more than half.
Are you sure your battery have this temperatures? Sounds like the cpu for me instead.

I am 100% sure. Are these temperatures good or should I give my phone back for warranty?
I will add that I always charge the phone from 30% to 85%, apparently so there are less charging cycles.
When charging, the battery reaches a temperature of 36-37 degrees.
I never charge it at night. When I was sleeping, the battery level dropped from 30% to 26%, that's ok, right?

Hmm thats a strange behaviour. My battery has 27 to 30 degrees at charging. Im checking with aida64.

I found the characteristics at the link:

Temperatures look similar, how do you rate my temperatures? Should I care?
Edit:
Could any of you do a stress test from antutu? I put my results below. Next to it is the battery temperature right after the test, which reaches almost 40 degrees Celsius. I will add that I have a case from xiaomi.
Hi,
I noticed that my phone's system temperature while using bypass charging and gaming is around 35 to 42 degrees and 30 to 35 degrees when idle. i reckon heat is the greatest enemy of the phone's durability
. Don't you think this is a bad sign for my phone?
It is actually a very low temperature... I never saw a phone that cool with such power inside. I get it as well without Bypass charging. All the premium phones I had was running hitter than that with a place on the back very hot.
If i use the official fast charger .....charge up to 100% the next day I barely get 16 hrs and 3 hrs screen time..wireless charge slowly and I get 30 percent more .
Anyone else see a difference??
Uk unlocked s21u for reference.
You sure there are no other factors involved?: types of apps you ran, heat, etc.

That sounds interesting! Would love to look into this a little deeper.
Could you describe this in a little more detail please? Like when do you start charging, how long it takes with each method, what your usage pattern is like, and what you mean by 30% more (SOT, Standgy, or literal battery percentage remaining)? And any relevant screeenshots would be much appreciated.
Fast charging will not engage if the temperature is too low. It will remain disengaged for that charge cycle.
Charging is an electrochemical reaction that needs a certain temperature range to function properly.
Minimum start temp is 72°F but 82-90F is optimal.
Anything below 72F brings the risk of Li plating which will permanently degrade the cell.
Charging will also shutdown if the battery temperature goes too high.

I don't think OP is talking about speed of charging. We're trying to discuss battery life with different speeds of charging.

It should be near identical.
Android battery capacity sensing always left something to be desired.
Battery temperatures should be made the same when comparing.
Try comparing battery voltages rather than indicated %

Depending on how fast the battery is charging it may shutdown at a lower charge level to avoid overshooting the correct shutdown voltage.
Samsung is said to be very conservative with their charge curves... I wonder why
Samsung should be using graphene batteries by now. Instead of throwing all their resources at the Folds, which never have sold well, they neglect their bread winners. I just reamed them out over that today

Said they should be using them already, among other things. Before the 10+ was released there was speculation that it might have a Graphene cell, lol.
I was barely aware of this technology until a few days ago... it be cool and it's in use.

30% more seems to be a huge claim .
5%-10% could have been a margin or error.
I'll have to do some tracking and get some screen shots . I normally wireless charge overnight and it says 100 % every morning and I use 70 % battery on average . But 1 day a week I have to charge using the lead . I only have the "super fast" charger and lead and the next day the battery is always worse by quite a way . Dead by 19:00 hrs. Similar usage most days . Its as if on fast charge it says 100 % but is way down.
As said I'll do some more investigation.

You know that you can toggle OFF fast-charging and super-fast-charging in the battery settings right?
Try that.

Samsung better listen then.
These batteries should last us 4 years easily. Anything less than that is a rip off.

With heavy usage the Li's are good for 1-2 years. Maybe better in a temp controlled environment.
I stream a lot and that's hard on the battery which is why I now say... live and let die
It's typical for batteries to last longer the slower they're charged. If you're using fast charging when plugged in, you'll see a decrease in the amount of charge that is held throughout the day, compared to wireless charging which is quite a bit slower.

Are you sure there aren't any other elements at play? Examples include the applications you used, the temperature, and so on.

So you're saying if one battery is slow, one is fast charged, both to 3.2 volts, the slow charged one will yield mAhs.
Unless the battery is degraded I have my doubts that it be a significant difference.
