High running temperature

I know there is another thread about this, but I feel that it does need bringing to everyone's attention, as it may not be a hardware issue...
It seems that when I have my diamond on charge, the lower section of the rear of the case gets very warm. Now at first, I thaught the battery charging or being under load was the issue, but it seems more like the area which is heating up, is the area where I assume the CPU is (to the left of the sim card slot as you look at it form the rear). When I disable all of the wireless devices it has, the temperature decreases a little, but even when sitting idle on the desk with the backlight at it's lowest, it still seems to get warmer than i'd expect it to. Not only does the rear of the device become warm, the metal sides of the case become rather warm as well, and the lower panel with the buttons in it also warms up to about the same temperature.
Could this be a faulty device, or is this actually a recognised feature of the device? (I have an O2 XDA Insignia/Diamond running in GSM mode currently). I have read that others are suffering from warm temperatures, and I'd like to know the cause, even if it's not possible to fix it.
Thanks for any info...

I've got a compact IV and mine runs hot whenever I have tt6 running, suf the net, use youtube - you get the idea -so it's not the battery. It was a lot worse before I flashed a custom ROM.
Before I got my phone I phoned up T-Mobile to check for stock and one of the stores told me that they had to send their stock back for replacement as there were problems with the phone overheating. This was also discussed for the Compact IV on another thread.
I've had my phone for a few weeks and it seems fine - just hot when I run certain programs...

it is a documented aspect of the phone... read this PDF
http://member.america.htc.com/downl..._Diamond/HTC_Diamond_User_Manual_Asia_WWE.pdf

when in idle htc isnt hot at all, but when chatging or using gps it becamo really really hot. but when using wlan,opera,msn,etc it isnt hot even worm, the temperatures are ok.

what he said

3 situations I've noticed mine the warmest.
1 - On charge (with the screen left on)
2 - Running TomTom 7
3 - After a long-ish phone call

It seems the temperature goes in line with the CPU usage and the battery discharge.
Sometimes I can feel the phone being hot in my pocket, even when in standby. I installed a taskmanager to see what application is taking so much CPU power. When I switch it on, I can see the historical CPU usage being around 50% (when the phone was in standby!). Unfortunately it drops immediatly to a reasonable 4-5% and so far I could not identify which application is the cause.

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] How do I solve my terrible battery performance?

I got a refurbished AT&T Galaxy Note 3 about a month or 2 ago. From the very beginning the battery has been awful. On a full charge--which takes at least 6 hours--I can get about 4 hours of regular use (i.e. no games, just web, maybe some maps, email, turning off Wifi & GPS when not in use, lowering the brightness, etc.) and sometimes up to 8 if I don't use it at all. If I play a game or listen to an audiobook, I get maybe 2-3 hours. Even if it's plugged in to the charger, the battery will slowly drain if I'm using it. The phone is also very often really hot.
As suggested on other threads about battery problems, I've downloaded Battery Doctor to help close open apps--and that's given me a tiny bit more time, but nothing substantial. I've also been using GSam to see what the problem might be. 25% is used by the Android Sytem, 22% is used by the screen, 11% by facebook (which I've started force quitting), 8% by the Kernel, 8% by the phone radio, etc.
Nearly everyone says what a great phone this is, but I just find my self seriously limiting how much I use it--which defeats the purpose of even having it.
Any ideas of what's going on? Anything else I should be looking at or trying? Between this and the fact that I can't root (I have KK), I'm about ready to sell it and go back to an iPhone.
Thanks.

You may have a bad battery, pop the back off and replace it!

First and foremost, try and figure out what might be hogging up all your battery.
Go to System Settings -> General Tab -> Battery
Look at this list of apps that are eating your battery up. The top 3 are usually 'Android System', 'Android OS', and 'Screen', depending on your current usage (unless you have been loving up a game or other resource intensive app recently, in which case it will be up top). If you see an app that seems to be eating away at it constantly, even when you aren't usuing it, try uninstalling it.
You might also have a problem with wake lock (where an app, or apps keeps your phone from going into its deep sleep). If your phone is rooted you can get the wake lock detector from the app store and use it to figure out what is causing the problem.
If its a system app that casuing wake lock, or just eating through battery like there is no tomorrow, it might be a known bug someone can help you with.
Also a thing to consider is the health of the battery. You say its a refurbished phone, who knows what that battery has been through (if its not a new one, no idea if they do that for refurbs). Its not a cheap option, but if all else fails getting a new battery might be the way to go. Also if no else fails there is as they say the nuclear option, as in doing a good factory reset once or twice.
Hope all that helps

Battery drain on Kitkat is a common problem, but that is ridiculous. Sounds like to me that you have a messed up battery. You should be able to call Att and have them send you out a new battery. Or Samsung might have to send you out one. I don't know who, but the battery should be covered under the warranty of the phone.
EDIT : Also, check if the battery has any bumps, dents, etc.

Might try turning off location services as well
