[Q] Battery heat ?

Hi.
While playing games my Xperia Play produces lots of heat. The back of the phone, and the gamepad feels really warm.
I checked the temperature with Battery Monitor Widget and when I don't use the phone it stays around 25-30 degrees Celsius, but when I play games (even 2D ones) it goes up to 38-40.
Is this a normal thing or there's something wrong with my battery ?

I can confirm this happens. Basically it is using more charge, therefore as a side effect of that it produces more heat from the chemical reaction. Same thing when you have it charging.
It isn't horrible, but try not to let it get too hot as it may shorten the lifespan of the battery.

So this is true for all xperia plays that after some time of gaming the phone will be really warm ?

The phone will get warmer, of course... but 40 degrees is not excessively hot. It feels warm in your hand, but it's not dangerous. A dangerous temperature would be close to 50.

The highest temperature that I had was 44 degrees after a long Nova 2 session.
I am a bit worried by the fact that while browsing the net through wifi the battery heats up to 38 degrees, but it's okay as long as it's less than 50 :> ?
Thanks for the help.

I'd say if it goes above 46 or 47 you just switch it off for a while. Not only because you don't want to overheat it, but because running the phone on higher temperatures reduces battery life (higher temperature means higher resistance to conductivity for metals).

Thanks for the into that it's perfectly normal for the phone to feel warm.
Have you ever reached 50(or that 46,47) degrees on Xperia Play or any other phone ? What app made your battery that hot ?

My former phone, the Galaxy S had HUGE issues with temperature while using 3G. Every time I toggled it on, the phone became awfully hot and the battery drain skyrocketed. I got it on 53 degrees once, since it was in my pocket. I was a bit scared, but the phone resisted it. Still, it wasn't pleasant.
The advantage of the Xperia Play being bulky and plasticky is that it's hard to bring it to extreme temperatures. If it's hard to make it hot, it has a positive impact on battery life as well.

Yea, this happens to me all the time. When using anything that drains my battery it heats it up as well.

All batteries release heat as current passes through them. When the phone is idle, the heat released is low enough your hand doesn't feel it. As the current increases while gaming, so does the heat.
It's nothing to worry about. The batteries are designed to handle heat without being damaged.
Especially since android devices are becoming more popular in places like india, where there's a lot of ambient heat.

What is your battery temperature?

Hi guys, recently picked up a galaxy s5, and noticed it gets extremely hot.
Now I'm well aware smart phone get hot, especially when running intensive apps, but the s5 seems unusually hot. Also when I went into settings - display - brightness I get a message saying unable to increase brightness further this device is overheating
I've downloaded this app https://play.google.com/store/apps/details?id=com.mtorres.phonetester to monitor battery temperatures.
Can anyone comment on whether their phone runs hot, and ideally let me know battery temperatures please.
Thanks

Yes, mine does (an Exynos variant), and the maximum EVER it has gone is 40 deg Celsius, with the current latest update. But with the previous update, everything worked fine. Maybe we should wait for a fix. Don't worry much, everything will be alright.

Driving using GPS (waze) + Sunny time + Charging and I think I had 45 or something, maybe 46 but thats about it.

gets to around 40 to 45 degrees celsius while gaming

[Q] Battery temperature

Why my note 3 battery temperature is always high always around 32 ~ 35
Is that nornal?????

Yeah it´s absolutely normal If you start playing games temperature could be 50°+
Don´t worry battery has temperature sensor

That is normal . depending on your region temperature...
I live in South Africa where in the summer it gets very hot 30 degrees plus...MY phone will be 32 when idle...It never goes higher than 38 degrees though.
Now its winter in my country.Outside temp is 15-25 and my phone will be 20(idle)-30(usage after 1hr of use)
If you have custom kernel installed it may be due to you disabling DVFS

Plastic is a terrible heatsink. It doesn't hold off external heat and it has serious issues draining heat. Particularly when there is something on the other side of the plastic (hand, leg, coat, etc.)
Anything below 1ºC and above 45ºC (Idle) and you need to start worrying.
It's 24ºC right now, and mine's been idling at 26ºC on the desk (inside an otterbox commuter) for a couple of hours.

How hot is your galaxy S7 edge

Hi
So I bought my GS7E a week ago .. I started to notice that it heats so much when I use it
I just don't know if this is the normal heat for it or not so I wanted to know from your experience
so at normal base when I'm not using it it stays at 34-35C
When I use it for whatsapp, facebook an normal light use it goes up to 37C
when I charge it it goes up to 40C
and sometimes when it's in the car on in my pocket and nothing is running in the background it can go to 40C too
that makes it annoying to receive calls or to hold it and put it next on my ear
are these temperatures OK? or is there is something with my device ... what are your numbers

Oh that seems in my opinion to be too hot, Mine is in Idle at 28°-29°, when i Use it (WhatsApp, Facebook... etc.) at 30°-32° and when i Charge it it is around 33°-35°

According to AIDA64, my phone is currently at 42c whilst charging from flat.
It's certainly warm, but at one point I saw it hit 50c when charging and using the phone at the same time.

what is the temperature when using normally not whilst charging ?

what is version is your CPU ?

I have the Exynos Version

It ranges from 33-37C

I have the Exynos S7 Edge. Mine at normal temperature ranges between 25 and 28 degrees, but can go as low as 22 degrees if not used for a bit (I have Greenify set to close all non-essential apps on sleep). If I'm doing some basic activities like texting, taking a few snaps on the camera or browsing simple web pages, it will go up to between 29 and 33 degrees. If I use it for gaming, depending on the graphics, it will go up to between 34 and 38 degrees. I've never seen it hit 40 degrees, although I reckon if I pushed it with numerous benchmarks or an hour of playing Real Racing 3 it probably would.
Temperature wise, this thing is fantastic, the best phone I've ever owned. Under ten minutes on Minecraft on my old Note 3 and it would be uncomfortable to hold. I've never had that with the S7 Edge, although I can't speak for the Snapdragon variant, which I've heard doesn't handle temperature as well.

Thank you very much for this detailed reply

Heat

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 OnePlus 6 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!

Phone has not felt even the slightest bit warm to the touch no matter what I'm doing so far. Like literally stone cold 24/7.

Mine gets hot after playing 3D games. The heat is mostly at the top of the device around the camera area.
Fine in normal use though.

I've played a couple games for a while and it seems to only heat up on graphically intensive, but I mean that's expected. I played the stranger things game for about an hour and it didn't warm up at all. I switched to shadowgun legends, maxed the settings out, and it started getting hot within like 5 minutes. As Joe explained, it gets hot near the camera, but it isn't too bad and it cools down really fast, literally in a minute or so after closing the game.

Yeah, agree with all of the above. I should clarify the game I was playing was Honkai 3rd Impact on max settings which is fairly graphically intensive.

At what temperature does your OP6 hover at.
I don't play games.
As per cpu-z, mine stays between 30.5 to 39 degree Celsius.
(The temp here in Punjab, India reaches 47).
It feels like warmish after I installed Apple music app yesterday.
Before that didn't feel any warmth.
Thanks.

I tested cpu-z for you and got very similar temperatures. I was at around 28°c after turning my phone on. It went to around 31°c when scrolling through twitter and listening to Spotify. And after playing showdowgun legends for a few minutes it got up to 38°c.

I'm no expert, but since we have similar temperatures, I'd assume it's completely normal.

Yup, same temps here. Nothing to worry about.

Hi..
Could test with the cpu-z app as to what temperature your set reaches when it's the warmest.
Mine has reached almost 39 degrees Celsius when using for everything other than games, for an extended period.
Sometimes though.
Usually it stays around 31 to 35 degrees Celsius on Cpu-z ( its peak summer time here in India, with daytime temperature always above 40).
Above what temperature should one get worried?
Cheers

you "worry" above 80 degrees Celcius, but I dont like it to get much higher than body temp.
I does cool off fast, But it can get really warm sitting in the sun.
I leave mine in a holder on my dash while I drive, playing pandora via bluetooth, and it can get pretty hot.

A few minutes of use, Pandora playing through internal speaker. Heavy JavaScript use on web browser.
It should be noted that my OP6 is Rooted and DeBloated.

Still not clear on one thing.
As to how hot is worrisome?
I spent a full hour browsing Chrome, in a car in a parking lot with no AC on and outside temp hovering at 38-39 degree centigrade,
and my device's battery temp (as on cpu-z app) went to about 41.2 degree centigrade.
I turned the AC on and within no time fell down to 34 centigrade.
Is that normal behaviour?

Of course it's normal behavior if your surrounding temperature is that high

Did you notice, the manual says:
Only operate your phone between 0-35°C temperature and 35-85% humidity
Click to expand...

The maximum ambient charging temperature of the equipment declared by manufacturer is 25°C.

Good luck with that in the summer!

I'm finding the screen does get noticeably warm to the touch at the top area near the SoC, just from normal use (such as using Chrome etc). Battery temp rises to about 35 degrees.
A little concerning I'd say.

Another disadvantage of glass back (beside dirt, fingerprints, fragility)
