How much heat can the N1 take?

So the other day, I forgot to close an app down--the Schwartz Unsheathed, if you are curious--and when I fished my phone out again, it was hot. Very, very hot. Battery information indicated 41C which, in the grand scheme of things, isn't that high (wouldn't worry me with a PC's graphic card, for example, or CPU) but it felt incredibly warm to the touch. Fine, I shut the app down, removed the battery cover and let the phone cool down. No problem.
It might be the apps I've been trying since then, but I have been experiencing performance and stability issues. Things slow down sometimes. On the Desire ROM, Rosie kept force-closing every now and again. On Enomther's which as we all know is just about the stablest thing that ever stabled, Launcher2 does ditto (the Launcher Dock may be the culprit, though, as it seems to do some weird **** and I've removed it since. Fiddling around with BetterCut also seems to cause force-closes). So could that be it? Did the phone overheat (but if so, shouldn't it have shut itself down) and now something's broken? Getting antsy. :/

41°C should not be a problem, but consider that this was a measurement from the battery pack and that a sensor like that can easily go +/- 5 to 10 degrees.
so well, some chip on the nexus could have gotten way hotter than 41°C. maybe something fried, some defect that was already there and now its really broken.
still, this can be a bit subjective, the phone will seem broken if you think it's broken you can always do a factory reset, reflash the current rom and try from there.

Yeah, could just be my own jitters--I'd experienced issues before, usually caused by a ROM or whatever--and lately my PC's been having problems, so it might well be some kind of placebo effect. Unless it and my N1 magically entered a symbiosis or something.
Thanks for the quick reply.

once my phone accidently fell onto my bed and under my pillow while i was charging it over night and i woke up at 4 am and found a burning out nexus under my pillow. i unplugged it and nothing seemed damaged but it still worried me.

I think if you are worried about it and you are rooted you should install SetCPU. It has a profile designed so that is you his a preset temp it will down clock your CPU.
I use setCPU to save my batterylife ie.
100% - 50% run full cpu on demand.
Idle/Standby downclock to 400Mhz
50% or less down clock to 600Mhz on demand
20% or less down clock to min.
I also complement this with locale for low bat. dimness, wifi off, bluetooth off. etc.. etc.. ( a little off topic I know)

Well, looks like updating More Icons Widget was what did it; things seem to work okay now.

Was wondering what the maximum advisable temperature is?
Maybe the phone has protection for the CPU? but Li-ion batteries dont like heat, it shortens their effective life.
my battery reached 44.3C yesterday on a 4 hour journey in the car using co-pilot and the phone actually net discharged despite the fact it was on a 1A USB charger for the entire journey - about 80% at start of journey and 20% at end.
I've installed setcpu now and set the temperature profile to drop the max speed to 768 if temp is >44C and another one to drop the speed if power is less than 30%, may need further tweaking though. This was not in my car and the back of the phone was effectively unventilated, in my car I have an open backed holder near an air vent.

What's your phone temperature right now?

I've been having some abnormal temperature in my N1 today, and it's got me a little bit worried. It's at 35ºC right now, while not doing anything. It's been a hot day alright, but I doubt that can have such a strong impact can it?
What is your phone's temperature when idle? What can be considered "outside normal"?

31c in the daytime, 28-30c at night.
i believe its safe, anything under 45c

It's weird though, it had never done that. I even turned it off for some time, but still. The antenna cover is definitely hot.

26.3°C right now.

26.6 'C here now..

Right now (indoors with cool temp) its at 80.6*F
Outdoors mine will get to about 90 - 95*F usually since I am using 3g, sometimes GPS, and the brightness is maxed out.
I dont let it get passed 99*F though since that would harm the battery. Good thing is though is it's never gotten to that point

32C right now. I've gone over 50C when using it as a GPS in sunny weather. Battery seems to be fine. Replacement battery at $25 (cheaper if you shop around), so I figured an average battery lifespan of 1 year isn't a big deal.

Damn, you guys have cold phones. Ive never seen my phone below 32c. Even if I check in the morning right when I wake up.

25C.
Lowest I've seen often is 21-22 C, but that is only overnight and I put my phone on airplane mode.
For those of you with hot phones, do you live in hot climates? I've noticed my phone stays warm when I'm out in the sun.
Also, make sure you don't have widgets/etc syncing all the time. I set them to 1 hour at most, and often 4 hours.

29.6.......

Running FroYo and OC kernel atm, so usually range from 26C-38C, anything higher than 40C freaks me out so I set up failsafe on SetCPU. Lowest I've got was 18C/19C with Enom's 1.8.1|IR's kernel.

Got widgets, news, contacts & email synching all the time. So my phone is constantly over 30c. Goes under 30c at night time (less activity perhaps). Regardless, the battery should be sufficiently warmed if you want to keep a charge. Just don't hit the 50C mark too many times though, which is pretty much unavoidable when you use GPS a lot.
But I've noticed that after upgrading to Froyo 2.2 the battery seems to run cooler and drains much less compared to 2.1. That and a boost in performance is short of ingenious on Google's engineer's part.
However, I reverted back to CM 5.0.7.1 cuz it's just not as polished yet. Waiting for CM6 instead.

I think there definitely is something wrong with the phone... I woke up and it was cool when I took it from the stand, then I browsed a couple web pages and I canalready feel it getting warm. It got burning hot when I charged it yesterday, too.
In case it is a hardware problem, what could be the cause?

I've just removed the battery and, surprisingly, it's cool. It's the antenna cover, the plastic part at the bottom where it says HTC, that seems to be getting hot. Does that even make sense?

Galaxy S getting hot at times? Or is it just mine?

I've had my Galaxy S for a week and of all the reported problems the worst for me is the phone gets hot sometimes in use and while charging. I checked in the application system I downloaded from the android market and it showed temperatures up to 53 degrees celsius. This makes the phone impossible to hold to the ear for a phone call and even internet browsing difficult as it gets too hot to touch.
As a side note unless the carphonewarehouse offer you a 7/14 day return policy don't buy from them. I'm having problems now because of it.
I can't post links to the pictures I took showing this as my account is still new, but it's on picasa web album under galaxy s temperatures and I can send you the link in a message if you want.
Has anyone else experience this problem?

I did notice that the phone can get quite warm at times. But for me even after 1hour in the sun outside the phone wasn't uncomfortable to touch. Much less to hot to hold to the ear.
My phone is charging right now and temp is 44 degrees centigrade. But considering the room-temp is almost 35, its not that bad. I'd rather have my phone becoming a bit warm than it taking forever to charge.

Ive only noticed this when gaming and charging from AC, its not that big a problem for me really, all smartphones suffer from this to some degree. My old Touch HD would get really hot if just wifi was active which is more annoying than this.

Well I have the desire as well and had many smart phones in the past that got warm but never as hot as the galaxy s, nor as frequently when used. It doesn't stay hot, but when it gets hot I can't put it to my ear to phone people. It happens mid call after I've use the phone for awhile.

Well that doesnt sound right, mine doesnt get hot like that, so perhaps yours is faulty?

Same here (USB also)
but other than that the phone remains colder than my HTC Magic.
It does get hot sometimes during calling but not that much.

I just got a new one (old one replaced) and I'm disappointed I'm suffering from this problem also. Mine also reaches up to 53 degrees.

have same problem but....
I downloaded a app "Advanced Task Killer" and killed all the apps that were working in background and i use from time to time, like YMessenger, Mail....
now the phone even if its charging the temp is between 35C and 40C. and maybe the battery will not discharge that fast

well it gets warm here 2 . but i had the same with my iphone 3g .i think its the working of the processor that makes it hot .its the same as with a pc when you run it to its high performance it gets hot 2

that sounds like normal
my old HTC Athena, gets really hot after long sessions of WiFi, 3G, or GPS, and in the SGS i get similar temperature when using the same stuff.
no heat from Bluetooth, or at least it's not noticeable
but ALL cell phones gets hot after long voice conversations.

Some times
Allways when im playing games my SGS gets pretty hot but not in AC .

From the troubleshootig section of the manual -
Your device is hot to the touch
When you use applications that require more power or use
applications on your device for an extended period of time,
your device may feel hot to the touch. This is normal and
should not affect your device's lifespan or performance.

It gets quite hot sometimes. Battery might rise from 33C in idle to around 45C on load.
I think it is the GPS chipset doing really weird calculations. That happened to me in the hardest math classes in college. Whenever I was totally lost and clueless about something during a calculus test I'd always get nervous and hot and sweaty.
Never killed me tho. I think the SGS will be fine even while hot.

I had the VIbrant for a week now.. i can't really say its gotten hot... maybe once.. but its not something severe, because i can't really remember how hot it was...
but from my research... iPhone4 is doing it, people complained they couldn't hold it close to their face while talking..... All the 1ghz SnapDragon's been doing it...there has been reports of the device too hot to even charge....even the underlcocked Acer Liquid E....
I've actually overused it the first few days...i can't really recall this happening to my phone...

Charging with screen on made my SGS rather hot. So now I try to leave the screen off when charging. Come winter that might change, not always a disadvantage to have something hot in a cold car

Seems to get hot in a location around the SIM card area on the phone when charging from USB or AC.
Not worried about it though.

Today try out the Fancy Widget, but later uninstalled it, I already disabled auto refresh everything, but my SGS get overheated and battery down by 50% just in 5 hours.. ......Anyone know why?

charging time
How long does your phone takes to charge ?
Mine takes about 3-4 hour hours on pc usb and about 3 hours on power adapter come with the phone.
My HTC tytn2 with extended battery 2800 only takes 2.5 hours to charge over the pc usb charge.

Mine's getting a little bit hot after trying some 3d games (asphalt i.e, i don't play too much) or clips (few minutes). it seems to have a particular "hot spot" at the portion of the sim card/sd card, the rest of the phone feels quite cool, and i can hold it without any hassle.

Charging the phone at the moment. 42 celcius.
Are you using setcpu? 10 mins ago I was using setcpu and noticed my phone gotten hot suddenly - I didnt do any sort of ocing. Checked the temperature and was shocked to see 53c Uninstalled it and the temperatre returns to a more acceptable level

[Q] Battery charging paused by too high or low temperature

Hi,
I've tried to search for a solution but haven't find any. You know there is a message when battery temperature gets too high then charging stops. The popup message is very very annoying: I use navigation and blackbox while driving. And when this message comes I have to press OK, and 5 secs after it appears again... very very annoying.
I agree with not to overheat the battery but why not just stop charging without this message? Is there any trick to eliminate this? In summer time and sunny days this msg comes very often. I have to place a piece of plastic to car's ventillation hole to minimizing the chance of this msg.
I don't care if it's charging or not, I just don't want to see this msg.
Please help if you have any idea!
I'm on stock JVR now, rooted, underclocked @ 800MHz. Other ROMs (CM7, MIUI) just stops carging without any message.

Had the same problem awhile back,reflash jvr, and dont use undervolting/overclocking programs/kernels.

+1 Dont OC/uV too much.

My apologies guys, but please read: I don't use OC/UV, I use stock and underclock.
With normal use and simple charging everything goes well but under heavy use I get this message while charging. Under heavy use I mean navigation, blackbox, and of course phone is at the windscreen while heated by the sun. The phone's glass is hot. It's normal of course because I use CPU intensive apps.
I repeat: I don't care about charging or not, just want this message to be disappeared.

I just unplug mine from the charger when this pops up. It happens with me in exactly the same circumstances. GPS navigation, dashboard of the car, and bright sunny days, it's not an overclock issue, just high ambient heat source, high cpu usage plus charging.
I also find it's aggravated by the silicon skin case I use.

Yes I'm doing the same as workaround. But other ROMs just stop charging and continue when phone cooled down without any message. It would be very nice to just remove this message by a script or editing a script or something else (I'm not a dev just an "I-like-to-hack" power user).

DO your devices get extremely hot at all? Mine did ,to the point that it was to too hot to handle, im surprised the dam thing did not exploded.
As for removing the message i have not a clue how too, i do know however that is is triggered by the thermal sensors.
I can also recall this happening with my windows mobile devices a few times,this happened when the gps services were stuck working in the background.
In all occasions the only fix a found was to re flash the rom.

No, it's not too hot, it's just warm enough. I don't say it's abnormal because in direct sunlight while charging and using cpu intensive apps it's normal. Just try to figure out is there any chance to do this all without this message...
Ok, I'll wait for someone who knows something or know someone who has seen someone who know something...

Referring to other threads I'm not the only one with this problem and not SGS is the only one with this problem.
While this message is not needed and has no function it has to be eliminated some way because tapping OK is very disturbing while driving/navigating/etc...
Script? Kernel patch/hack? Something? If some ROMs can do it (like MIUI) there must be a way to have it disappeared...

I had the same problem with a Galaxy S II today. First, it began to warn me that was starting charging. And 1 second later it warn the Power Saving was activated and the charger was turned off.
Later, it said 'Charging pause. Voltage too high'. When I've tried to power off the phone, it was powering on by itself.
During the morning, I've used the phone to consume battery. At the afternoon, I put it via USB cable and it seems the problem is solved, for now.
I'm using the ICS ROM beta, by Samsung, have some days.

HTC One M7 Battery Drain and Overheating

I just replaced my aging iphone 4 with an HTC One M7.
So far, I'm loving having an Android phone, and I'm really glad I switched, but I seem to be having a problem with the phone.
It is getting pretty hot and the battery is draining alarmingly fast.
The phone was reset to factory settings when I received it yesterday, and it is the AT&T software version. It is on Android 4.4.2
Although this is my first Android phone, it is not my first Android device (Xperia Play used as a portable emulator, Nvidia Shield, Asus Memo Pad HD7) so I knew the obvious things to try.
The phone feels slightly warm at all times, even when just sitting in my pocket. When I have a CPU-intensive app (youtube for instance) running, the phone gets pretty hot.
I understand that the aluminum chassis transmits heat very efficiently, and that this phone should feel warmer than a plastic phone, so I installed a CPU temperature app.
I'm getting in the high 40's to low 50's (celsius) with no CPU-intensive apps running.
Looking in my running apps, I don't see anything that looks like it is making heavy demands on the CPU.
While at work today, I put it in airplane mode (but kept wifi on) because I don't get a very good signal at work anyway, and I thought this might be causing the battery to drain quickly.
I forgot about this, and so the phone has been in airplane mode since 1pm today (it is now 8:45).
While browsing the internet just now looking for a solution to the problem, I watched as the last 18% of the battery drained down to 1% in around 15 minutes.
This is in airplane mode, with battery saving mode activated, Blinkfeed deactivated, and the screen on minimum brightness.
Does this sound like abnormal behavior?
I need to know fast, because if there is something wrong with the phone, I need to return it without delay.

Is the phone brand new? It runs more the first time you turn it on, I think due to some profiling. If it's still like that the day after turning it on for the first time I'd probably be concerned. It could be due to something you've installed--what have you installed (if you don't mind sharing)?
I've definitely experienced what you're talking about on CyanogenMod, but never that I can recall on the stock ROM. When it happened on CyanogenMod, rebooting generally seemed to fix it.
