Is it dangerous heating the phone to up to 41C every day?

So I started playing this game Order and Chaos Online (kinda MMO similar to WoW) and the temps get very high, up to 41C on WiFi and 43C on 3g. The phone is burning to a point that it hurts my hand. I'm playing aprox 2-3 hours per day, sometimes maybe 4 hours, how dagerous is that to the phone? Can it do any significat damage over time?
I am using the jame bond kernel at 1ghz, which is also a bit undervolted, don't know the values tho, governer is set to ondemand. I tried to underclock it to 800mhz but the game lags sometimes and is a no-go.

ukhm, khm....

Well if the phone is heating up and it sounds pretty bad, I'm pretty sure its dangerous. Maybe not, but IMO it is. My Sprint HTC Hero has over heated a few times and after that it had small little dots on the screen. Hopefully your phone don't fry.

What are you usual temps? Do you ever get any values similar to mine?

Mines usually sits between 34°C - 36°C, its seems like a normal temp IMO. I've never had my phone hit 41°C before and I sometimes i tether my phone via usb and it still dosent hit that high. If your is hitting that high, it could also be the temp around your home or something. But I wouldn't use your phone to play MMO, especially if your playing 2-4hrs everyday. Just saying..

Well I'm at stock right now because I'm waiting for the ota tomorrow. But I was using koushdecks 1.2.1 with matr1x kernel 4.0 bfs version. Clocked it up to 1.3ghz - 100hz, switched between smatass to ondemand everyone ounce in awhile and I still was at 36°C. I use setcpu's widget to always check my temp and it never goes higher then 36°C. Fact.

Can anyone else pls tell their usual temps, this got me a bit worried. On browsing the net I achieve 38C, on some intensive games I can get over 40C. When idle it usually stays at 30C, sometimes in the morning I find it with 28C. Is this normal?

What kind of heat can the g2x take?

I'm trying to set up a profile for setcpu. What would be a good limit for heat on the g2x before it overheats?

I say anything above 110°-115° I live in phoenix az that's under stating for most places though lol
Sent from my LG-P999 using xda premium

Honestly 110 is kind of low. When I had a g2x (during winter) I never saw over 108, but my other phone has been as high as 127 while playing a CPU intense game plugged in in the middle of summer. Shoot, I know all that's measured on a phone is battery temp, but on a laptop 140 processor temp is perfectly acceptable.

My profile is set for 45 degrees C which I do hit on occasion but I am a little paranoid about battery damage so I keep it low.

Tegra does not thermal throttle itself until about 70°C IIRC
now, letting it get that high on a regular basis is not the best thing for the cpu or the battery.
If your gonna set a profile, I'd recommend 60°C
my phone used to hit that every day when i was doing some hardcore multitasking.

That's crazy, I would never let my phone get that hot, the stock battery is only rated for 45c but again I am paranoid we are using LG hardware afterall

So you are saying 140°, I had to Google it lol, that's what you recommend is safe lol. I know you know what you're talking about you're one of the most detailed informative persons on the site lol, but damn that sounds crazy!

That is nowhere near a "safe temperature "
That is a omg my phone is 1337 haxxor pwning multitask your mom and my mom fast. Running any electronics at or close to their maximum heat/mv limits for prolonged periods of time will cause your phone to live fast and die young
Side note: My 3500mah and 1900mah batteries maximum temp is 50°c and when using them I adjust my setcpu profile accordingly although they tend to run cooler anyways...

Agreed, that just sounds like asking for all the cheap glue and poor solder job to fall apart. I wouldn't get that close if I notice my battery is any where near 120° I take the battery out and let it cool down...

When I first got my g2x I went through 2 lemons with bad hardware before the one I use now.
Even being counter active and setting your temp limit a little lower and then setting the profile Max CPU frequency a little higher may be a good idea you get a audible warning when you hit your temp limit (in setcpu) so might as well take advantage

Its funny how when i had the G2X, everytime i put it to charge it would get burning hot, now that i got a iPhone 4 it has no heating problems at all Okay let the Apple suxxx comments begin but we all know the iPhone is a better phone overall

That's cpu temp, allot of that dissipates by the time it gets to the battery. Yeah, running hot causes the life of electronics to shorten, but I'm not keeping this phone for more than 2 years at most, and batteries are cheap
Like i said, tegra is alright till 70, i get nervous around 60-65 your battery temps should not be any higher than about 50-60 (but that's just a guess)
I'd your setting up an emergency overheating profile I'd still recommend 60° but if you're hitting that too much you might want to tone down the oc in general
Don't worry about the solder tho, that won't melt till around 100° or higher
Note: all temps in °C

While Tegra is alright up to 70°C, I get skittish when I am required at some places to leave my cell phone in the car, which (in Houston) can get up to 60-65°C inside when parked in full sun. I personally recommend keeping it below 50°C as much as possible.

treat your phone like a child, please dont leave it locked in glove boxes or cars in the sun... or on a table in direct sunlight. (the sun is hot!)
i'd turn it off if you need to do that...

S3 get hot?

My s3 gets hot so fast. I'll be looking at tweets or browsing pulse and BAM. I don't even want to hold it, its so hot. Yes I am on a custom ROM, cm10 to be specific but this happens to me on stock as well. My governor setting are default for the rom, no custom kernels installed. What do you guya recommend? Should I return it and will vzw accept it?

How hot is it getting? Actual temps I mean.
Install system tuner and that will give you cpu temps. I can't think off hand of any apps except wifi tether for root users that will give you a battery temp.
Before I got a case I thought my phone was getting way too hot, turns out it was no where near dangerous levels but it was hotter than other phones I've had. It's just a thing with the S3.

I'm not sure what could be wrong but just want to throw in that my phone does not get hot at all, it doesn't even get a little warm, and I use my phone quite a bit, pulse is one of my favorites, I play a couple games etc. I am stock but was running CM10 and my phone never got hot.
Sorry I couldn't help just wanted to let you know that simply using your phone shouldn't make it hot, not sure why yours is like that.

What temperatures are in the "redzone" as far as the phone's safety. I'm Overclocked and will sometimes get up to about 120F, but have seen it get as high as 130 before.
To the OP, can you give us any numbers? I use System Tuner to find out mine.

The 4g is one of the biggest culprits for heat. My phone heats right up if I'm tethering or downloading directly. And I imagine there's a lots of back and forth data with Twitter along with the other browsing he mentioned.

Those temps are fine. If I have my phone plugged in and tethering I've seen low 150s. I usually try to cool it down at that point but just so it won't go higher. I've been told that 160f shouldn't hurt it.

Awesome! Thanks! My old laptop would often get up to almost 200, in fact it would idle around 180, but I was pretty sure the phones would withstand far less due to the fact that it is in a much smaller package and that there is no heatsink, I just wasn't sure how high it can go.

A CPU is a CPU pretty much. The heatsink just helps keep the temp down. Equivalent of taking the back of our phone and putting a fan on it almost.

Critical temp is around 180. Our phones will automatically shut down

Lol kindve dangerous if your not careful but I put my phone in a airtight zip lock back and ran cold water on the outside, cooled down pretty quickly. Dont let water touch the zip part of course, but maybe another option.

Thanks for the tip! i've been having the same concerns. I'll be downloading the system tuner software to keep an eye on the heat.

Noticed change to phones ability to take a charge
I had my phone get quite hot the other day after I switched to cleanrom 6.5 and now the phone doesn't want to take a charge like it did before. Could that be some indication of some damage done?
I didn't have the frame of mind to check the temp at the time. It was noticeable hot though. Even through the case.

I would advise against that. at the very least use room temp water, not cold. sudden temp changes are never good. could induce cracking in the glass or other components

[Q] Is it normal for Nexus S to get hot in Hot Temperatures??

The temperature in my city is around 40°C.. But real-feel is around 42°C...Summer has just started and my phone is getting hotter than usual... However, the phone is not so hot in idle mode... Its around 31-33°C.. However, after playing few games or browsing for around 20-25 mins, my nexus s is getting hotter and hotter.. I can feel it in my hands... But still, the battery temp is showing 36-37°C only... I've never even seen 38°C on my phone... But still, I can feel the touchscreen is getting very very hot...
After opening the back cover, I began examining myself.. I noted:
The battery is not that hot
The sim area is very hot (I even started my phone without the SIM card, but same result)
The area beneath the camera and flash is also too hot..
The touchscreen itself is getting v.v hottttt.... I cannot play touch games anymore... However, the lower part of the touchscreen is absolutely normal...
When charging, the temperature doesn't goes more than 35°C... However, I can feel the back side is warmer...
2months ago, when the temp was around 30-32°C, I've never had this problem Everything was fine and running perfectly... Still now, everything runs smoothly without lags
I've never heard that touchscreen is hott... I've had many phones and my city's temp remains mild mostly... So, what could be the problem?
I am using:
Carbon unofficial
Marmite 8.5cm_bigmen
No over/under clocking
Vooodoo sound with +5db (Hardware highest)
Ondemand with cfq
Battery timings: 1.5day with normal use (4-5hrs of screen time)
1day with heavy use (6-7hrs of screen time)
Should I revert back to stock ROM?
Is there any IC problem?
Battery problem?
Processor problem?
Or is it normal for the phone to get hot in hot temperatures (42°C)???
Should I see a doctor?

Its normal dude. If you want to keep it cooler than don't keep the brightness too high.
One thing that can REALLY heat up my phone is playing games at 100% brightness on a hot day so try to avoid that.

No dude the same areas as you describe are the ones that can get really hot on my phone.

My i9023 gets really hot if i play games at max brightness, so now I avoid playing games.
And yes, it also gets hot in the processor area, not the battery.

Now, my phone is getting very hot while playing Asphalt 6 or even Fruit Ninja... Only the processor side (Top portion of touchscreen and its back portion) is getting hot... Battery is definitely cool (Not more than 38degree)...
What could be the problem? My processor has gone mad or what? I've even tried undervolting as well as processing speed to 800Mhz max... But overheating remains

My phone gets hot only when I'm on full brightness and a game I usually put it at half brightness and it never happens even when playing mc4

This is absolutely true. I have Nexus S since 4 months... There was no problem at all then.. everything normal and running fine and never overheated at all no matter what i play...
This overheating problem started few days back when I tested overclocking and overvolting NS
Seem's this is the problem..
I think I have roasted the processor and it will always remain like that.. I will have to sell it soon now

It is... I am on 3% brightness...

Will it resolve the overheat issue?
Why is the processor heating up too quickly? Has I finished its life by overcloking it? Or it is a battery issue?

I went to the local market for some inspection of my phone. The person said that your phone is not giving maximum current and the charging ic is getting very hot and has to be changed... How is this possible? I've never had any problem with my phone like this... 100% charging was always OK for me

Heat issue ,is this normal?

I am running cm9(beast mode wifi calling one ) atm but I have a heat issue with my phone around the camera and speaker area where the phone is really hot but by the battery n bottom half it is much cooler.
is this normal for you guys? N gals? And even if I turn of the phone n it cools to 91 is shoot back up again

That's a 'feature' of the ICS+ kernels. While 100MHZ is the minimum, if it's actually set to that, the kernel is set to go back to 200MHZ anytime it gets the chance. You can watch this happen if your scheduler/governor app actually updates on current min/max speeds. ROM Toolbox PRO, SetCPU, ROM Control, and CM's Performance controls all display this shifting, though with luck you can sometimes get it to stick at 100MHZ. It just takes some persistence.

The modem on the phone isn't very good.
It even happens on stock where if you go in and out of dead zones, it will "SEARCH" for network and become burning hot, so it's a common problem that happens year round. It's a great way to kill battery. That's also why if you leave you phone in a sock drawer, it's going to last longer than if it's in your pocket walking around.

I never got my phone to go into deep sleep when I selected ondemand (or maybe it was ondemandx). I would try a couple of the other governors & see if that would help.
Sent from my SAMSUNG-SGH-I547 using xda app-developers app

OndemandX gives me good sleep, but forces the phone to minimum speeds when the screen is off. That tends to cause issues if I'm trying to use GPS or music without the screen burning.
As to what will work best... that depends on unique your phone, its apps, any tweaks that have been made, and your specific combination of scheduler/governor settings. I'm a fan of SIO, but sometimes the tweaks make that (and deadline) stick at max MHZ, in which case noop is great. At various times, I go with any of the SA2-based 'intelligent' options (SavagedZen, brazilianwax, SmoothAss, or SmartAssv2) or the OndemandX/Conservative basic sets. The others have gotten stuck more often and tended to allocate more processor than I think it needs.

I've always had the best luck with smartassv2. I think it's a good tradeoff between good battery life and quick processor speedups in order to prevent lag, plus I haven't had the issue of the processor locking up while the screen is off.

That's usually the one I always fall back on too despite new ones all the time and everything, it's my default now on any ROM.
