Hi guys
I'm gonna ask this straight, my phone sometimes when playing games or using 4G gets a little bit hot, not so hot that it gets uncomfortable, but the battery's temp reaches almost 40°C. Is that something that I should be worried about? As I heard that high battery temps can reduce battery life with time and might even permanently damage the battery.
thanks
40°C is not HOT
Don't worry.
With your usage that is a normal temperature. Use a case if its too uncomfortable for you.
No worries. 5x runs cooler than most devices. Also our skin temperature is around 34C.

What are your average temperatures on your Desire? On standby mode, heavy usage (movies, gaming), charging and so on. I'm a bit worried about mine. It usually idles at 28-30 degrees C and gets up to 38 on heavy usage, maybe 39.
I also wanted to calibrate my phone using this method, but I never get passed 4182mV, a few months ago I was able to get 4197. The phone also seems to be pretty hot, even when it does nothing.
The battery usage is ok, I don't have any apps that are using the CPU in the background.
And I used an undervolted kernel, running at 875mV at 245MHz.
playing ROBODEFENSE for 20 minutes or more gets my desire very heated.
so much so that it shuts off
is there an app or similar that can show me the temp of the phone?
You can view the temp of the battery which can give you an indication.
If your phones are overheating, send them to HTC and they should get repaired.
I just checked and my phone idles at like 25c and I played RoboDefence for a whole level at lvl 100 and got 35c. To be honest, it felt warm and not hot. I've had it hotter than that but never had a reboot issue.

I seem to be getting the same temps, but I still have the mV issue. I can never go above 4182mV and I can't properly calibrate the battery. The phone also dies at 11-12%, when I bought it it was dieing at 0%.
Sometimes, the phone is charging and it shows 87-88% for some minutes, and suddenly it jumps to 100%, I guess that would be the loss of 12% when my phone turns off. I wiped battery stats when I was at 100% and no luck. I am using latest snq's kernel for leedroid ROM.
Maybe a naff battery?
Yeah agreed.it can get hot at times but if it rebooted better sent it for a check

My battery temperature rises to almost 45.c+ after a few minutes of HD gaming on my Stock HTC WFS Rooted, Is this normal or theres something wrong with my battery.

the phone has to heat up especially when you play games that use a lot of cpu and gpu...
but idk is it normal to heat it to 45 and more... i think that 50 degrees is a MAX that may happen, and that reffers to battery heat? I mean its just going to shorten life of battery, extremely ... and about processor i think u dont have to worry... it can stand some heat ... i have read that temps went over 70,80 celsius on the phone, and they were still running fine. Of course its not recommended, as you can guess
I don't think that it will be a problem. I have my phone running that hot for four months already when charging, and when not plugged in it also easily reaches 40c. When I dial *#*#4636#*#* my battery health is still good. Also note that on the back of the battery it says that the max operating temperature is 60c.

Never looked at the back of the battery that closely, that clears my doubts.
I've noticed that mine (and others report) their SGS3's run particularly hot. This is most likely due to the dual core processor, the processor seems to be located at the bottom right of the phone (by the back softkey) as this is where the phone is the hottest. Im in Arizona and during the summer temps outside are excessive constantly over 100F. Even when in my home all day I can rarely get my battery temp down to 85F. Li-Ion batteries have a much shorter lifespan when exposed to temps above 85 and when exposed to excessive temps are also prone to "thermal runaway" in which the cells become so hot that the battery continues to self heat until catastrophic failure in which there is so much pressure built up inside the battery that when the casing fails it essentially becomes a flamethrower. The dell laptop battery recalls were caused by this, a flame thrower in my lap doesnt sound fun but neither does one in my hand (unless im using a real one). The polymer plastic casing is a terrible heat sync (especially with a rubber case). It seems these batteries are going to need to be replaced once a year.
Looking at about a 35% loss in capacity within one year. I also experience terrible battery life, moderate use i get about 6 hours, screen eating up most of my battery and when in doors i keep the screen brightness all the way down.
Data found from multiple websites but do not have enough posts to site source:silly:
Wait.. You're complaining about your phone being 85f? Try over 100f lol mine gets to 42c.....very annoying

I got my phone there first day it came out and its rooted and overclocked and it stays around 28 C but goes up to ~40C at heavy use

Yes, these batteries are doomed.
I have been looking into the charging PMIC and if you can tell it to stop charging at 80%, but it appears to be hard set at 4360mV where it goes into a trickle charge mode and runs the phone of the USB power.
The problem is two fold. For one thing we have a 2100mA battery, and the charger is 900mA, so a 0.5C charging is good for long term battery life, even better if you charge over USB at 500mA. But the discharge rate can be as high at 1000mA if you have all the bells and whistles on and things are hot to begin with. The typical usage with screen on is 200mA, maybe 400mA with WiFi, more with BT. But current increases greatly when both cores are over 1.5GHz.
So the problem mostly seems to be the charging is reducing capacity by people going below 10% charge (if you graph the voltage you can see the tail off below about 15%) and charging above 80%. LiIon capacity is reduced by keep over 95F and also permanently reduced by draining to low voltage levels and also charging much above 4.2V and then holding the voltage there. I noticed the capacity after two weeks was reduced by 20% already.
And no, the thermal runaway is no longer a problem and I wouldn't mention it anymore. The battery self-protects, as well as the system is being very careful monitoring the thermals. Also, the CPU is throttled above 56C ( I believe)
But, I know in the PMIC controls you can disconnect the battery and run only on AC when plugged in. This would be ideal to leave charge the battery to 80% then stop charging it, and you could leave it plugged in at work or overnight without worrying about the battery capacity.
You lost 20% capacity in 2 weeks??? Wow!
I've had mine for going on 2 months and my battery seems as strong as ever! Still able to easily get over 24 hours off a full charge and still be above 10%.
I am not trying to be argumentative here but isnt the idea that going below 15% and charging above 80% purely myth? I've seen quite a number of people posting the same info in the past but when asked for a reliable source for their information they are never able to produce one. Im pretty sure I've read articles/studies that debunked it as well. (Ill try to find them but honestly may be thinking of something else I read. Ill let you know either way if I find it)
I do know its a good idea to have the built-in function that stops it charging around 95-97%, but isn't that just to prevent overcharging?
Also I should point out that my phone does often get quite warm, even hot sometimes, but it hasn't affected my battery life in any noticeable way.
As for your 20% drop in capacity, have you flashed any roms? The latest jb leaks have big battery drain issues. Also when you flash any rom it can take a few full cycles for the system to relearn how to accurately report battery use and can often trick people into thinking the battery capacity has gone down.
Like I said, not trying to argue with you. It seems you tend do do your research on this type of stuff so im hoping you can point me to where people are getting their information.

So I got this phone 2 days ago and I love it except for the battery.Anyways,the battery temp while charging is 34c is this normal?(37c while writing this in chrome)And I noticed that battery drains pretty quickly while gaming(like clash of clans)and hot from the back-top.So is this normal?n
Yes, this is normal. Having the screen on while charging will make it even warmer. Be aware that the phone charges more slowly when the battery rises above roughly 90F/32C, so keeping the phone cool will help with charging speed. Mine will drop from the max of 1600mA with the stock charger, to about 300mA, as the temperature reaches the low-90's F.
Thanks for the reply!
Yeah I noticed that.When ive put the phone in an air conditioned room,battery tempreture decrased to 31.5c and the voltage increased to 4300 mV.But I did a research and found that li ion max voltage is 4.2v anything up is dangerous unless the battery got some sort of overvoltage protection.So should I be worried?
No. Mine charges to 4.4V. I'm comfortable that this is a safe value for the battery.
If LG had it dangerously overcharging every single battery, that would be incredibly irresponsible. I'm sure they picked a safe voltage.
Guys - what app/s are you using to measure. I use Ampere but is there any better?
Thanks.
Just go to the hidden menu by dialing *#*#4636#*#*
That doesn't show the charging Ma?
I starting a gaming a little on my Note 4 and noticed the phone got very warm thru the case.
Battery Monitor shows the temperature was between 35c and 36c for about 30 minutes.
Is this too hot?
What is the normal temperatures for the battery and CPU for this Phone?
Googling did not locate the answer for me
Thanks
It will get hot when you play games but it will slow down or power off if it gets to hot.. if you have a case on it try taking it off when playing games
