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.

Xperia overheating

Yesterday using my in built sat nav my xperia went crazy 4-5 miles into my journey, with tom tt7 flashing on and of so I pulled over and took it from the screen mount, it was hot enough to fry an egg on , i did have my heating on as it was cold, also after closing tt7 the phone was randomly flicking through menus. I had to remove the battery allow it to cool for 10 min put battery back turn on and leave my heating off, thank god all was well and continued on my way trouble free for the rest of my journey. All has been well since it normaly does get hot during use of sat nav, wifi but this was very hot.

I have the same thing, it really does get incredibly hot, Maybe it is the GPS?

Hmz i've been using tomtom for about 3 hours and deviece was just a bit warm.

normaly does only get slightly warm, but yesterday it got really hot.

i wonder if it will explode..
u know.. since the battery is made from sony

I noticed this problem... it heated up a lot due to the car heating was on and the heat was hitting the X1... I have used the GPS in the past and never had problems... Its most likely the fact had the heating on... which made it HOTTER...
Generally warm and that it...
Cheers

I supose the heat of the car's heater was causing it to overheat (it's imaginable considering the metal battery cover, that as all metals do, easily heats up). I haven't had any temperature issues to this point and as far as I have checked (Batti allows to see battery temp), the temperature on mine hasn't come any higher then about 35C.

I have a different issue. With my one, It will be fully charged, and then it will start to over heat. After a couplr of hours, say about 5 hours (at work) i check the battery of the X1, and its only got 2 bars left and needs to be charged again! This is the second time it has happened to me. The battery wont even last 10 hours!

This is probably the problem of battery.

The times my X1 has got hot tends to be from a dodgy charger. It seems like the connector needs to be perfectly in.

My Xperia is getting really hot while using mobile data (GPRS/EDGE), found out that power draw with data connection on is about 500mA compared to usual 60-70mA. I think that battery just get hot thanks to this extreme power draw, but may be there is just some chip which heats up while sending data over 3G network.

hot vs crack
When I'm in the office the phone is permanently connected to my Notebook. It loads an stays in sync with my outlook...
Sometimes I thought that it feels a bit too warm. But usually I'm dropping it in my bag quite fast.
Last week I took it and It was really hot. It felt like the source of the heat was the Battery. The metal cover was nearly glowing.
The interesting thing is, that I also found what is called "THE CRACK" at the stylus holder.
I'm not sure if the crack was there before but if not...
I'm also having a Problem with a very short battery runtime. About 5-6 Hours on Standby. Batti also seems a bit confused. Shows violet loading color even if not loading from time to time. Iwas blaming the Touch-IT Manila shell I've installed, but I am not that sure any more. Going to test an write an Update...
Do the other heaters also have cracks in their cases?

Mine got quite warm today .. when I was running Skype and QIP, waiting for some people to send me IM. In 5 minutes it become very warm. Not really hot, but it was certain CPU is working 100%.
WIFI, BT, GPS was all off.
When I closed Skype and let QIP run, it seemed to go back to normal in few minutes. Next time I must check Task manager.

haha Im living in canada and its really cold here in Ontario so i dont think it would get that hot

I've observed for a few days that my x1 also heats up. but not to a point that it almost could boils an egg. if if you google "Lithium Polymer WIKI" the battery characteristics is that it heats up to a point that it can explode. that's a downside of the battery though it is better than li-ion in terms of life cycles, it is even said there that you can't leave a li-poly battery inside a car and it explodes while attempting to charge it in a zippo bag.

Mines usually at 40 deg C with wifi on

What week did your Xperias get produced?

I use my Xperia almost everyday for internetacces on my laptop. This means that it's constantly turned on, and intensively using the HSDPA connection for hours long.
When this happens, my phone heats up as well, sometimes more than on other moments.
Is it normal ?

29.8 °C at the moment, just take it out of my pocket.
After 5-6min bowering with opera 33.7 °C start to feels lilte warm.
Still 33.7 °C after installing and uninstalling simply .cab file.
After soft rest still 33.7 °C
Change to media panel play some music and watching videos 35.0°C, feels warm.
Sometimes I can get it 37-40°C in normal use, installing some .cab's and using some random programs etc. It's warm but I think it's normal.
I think it's battery what heats the phone and what voltage/electricityis it's using at the moment, more and longer using programs,
wifis, etc it uses more power and heats the battery, and when there is no any fans or etc cooling it only heats,
after u let it down in your hand and let it cool. Sounds logical to me.
Highest temperatur that I heve get to my xperia is 48°C, It was ****ing hot and it rly never can get that hot whit normal situation,
playing music, bowering, etc. It was in charge, never happened again,
normal charge temperatur in my x1 is 40°C or lilte higer.
Hope this gives some answers.
Sry for my english btw.

my fone is at 46C now... im chargin it from pc usb n talkin on da fone using BT the weather now is about 27C... sometimes i get like 48C 49C when in da car using tomtom 7 for about 1 to 2 hour... n da weather outside is only 50F...
is this normal?? will my fone explode??

N1 Overheating While In Car Dock

hey guys,
I got my car dock a couple days ago and started using it day 1.
impressions:
its sexy but a little hard to move around (prob cuz its new)
but i have a major problem with the nexus one heating up to almost 120 degrees Fahrenheit! and this troubles me cuz i dont want my battery to lose its charge capacity.
and if im on lets say 50% battery and i drive somewhere for 10-15 min using the navi on the car dock
the temp shoots up to 115-120 and the charge goes down to ~30%
anyone else having a problem with overheating while in the car dock?
i used it during the day and night (only to check if the sun was affecting it)
no change in results
i used it with every option on the power control widget off
i ran Advanced task manager and ended all apps before launching navigation
im considered a tech whiz
so ive put this thing through its paces
and they only way to not have my phone burn hotter than the atlanta summer sun is by turning the screen off and listening to the navi...not veiwing it while its on charge and keeping all wireless options and sync off except GPS
ideas greatly appreciated....
oh yeah
rooted n1
running cyan 5.0.6xx if its any consolation...
and its not undervolted...(problem? but then what about non rooted phones)
EDIT:
oh and today
after using the n1 and removing it from the car dock the screen was not responsive. couldnt use it to navigate
has to reboot the phone

I also noticed my Nexus heated up to 40-42 degrees C while using GPS with Screen on for 15 minutes. Burning hot.

no one has any problems?
ive been noticing its msotly because of the sun that it gets scorching hot but at night it does rise past 115 degrees F

120 degrees fahrenheit (49 degrees celsius) is not very hot for computer parts. The reason it reaches those temperatures I guess is because of google maps (if you used that for navi). When you use google maps it's almost constantly using your data connection and that is one of the most battery intensive tasks if I remember correctly.
Oh and I wouldn't classify a little over 40 degrees celsius as burning hot, I've been to places hotter than that, but I guess it's subjective

Seems that overheating is mainly an issue for those running Cyanogen's ROM, no?

My N1 can get hotter than 50 Celsius in under 10 minutes. It's really a bit frightening. I have noticed, however, that this ONLY occurs when the battery is not near full. Turning the screen off seems to help cool it down (more testing needed). However, turning off the screen doesn't help when you need it for gps.
I am using cyanogen, but not the cyanogen kernel. Overheating occurs both in sunlight and at night. I believe it occurred while not running google maps as well, but I can't remember for sure.

I've had no problems, but I did notice how hot it was. I figured it was because of the sun since I had it mounted on my window glass.

Google maps only uses a data connection when it initally pulls down the route information and when it needs to recalculate the route.
You can put your phone into airplane mode after the inital pull and google maps will still function as expected (Except it will not pull down new maps if you stray from the path).
The issue is that you are trying to charge the phone and use it at the same time. The mechanism for doing this charges the battery and depletes the battery at the same time, this makes a really hot battery.
Keeping the screen off when its not needed in the dock and you will have less heat issues when you need to charge your phone in the car dock.

yeah this car dock i am really getting mad at
i wasted 60 bucks for something that heats the hell out of my phone
i listen to music so loud the bluetooth speaker isnt loud enough to tell me where to turn when the screen is off so...
i guess ill try out enomthers rom with the UV kernal and report back
the major cause of it is the sun
because at night the phone doesnt go over 100 degrees F when using the navi

Does anyone having this problem use "set cpu"?
I had a the same problem because my cpu was set to 998 during charging. so then I had the three main things that cause heat ganging up. battery, gps and cpu. All i did was set the cpu to 806 while charging and the heat problem went away...
I imagine that the stockers don't have this problem because they are under-clocked...

The main problem is the sun. I have Rodriguez's rom with the overclock and the only thing causing it to heat up is the sun.
Setting the CPU lower I will try but on setcpu I don't set it to userspace anymore. Its set to ondemand and no profiles set. Ill set a profile for overheating at 120°F to max 806mhz

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] Is this normal for a battery?

First off, sorry if this is similar to another thread. I had very specific things happening so I thought it warranted a new post.
Okay, so I was wondering if my battery life was normal. I was browsing the web earlier for about one hour (looking for info on my battery troubled, oddly enough) on wifi. After I finished I noticed my battery had dropped significantly: from 79 to 58 to be precise. I use the lowest backlight setting, I kill apps frequently.
My ROM right now is Serendipity 6.1, stock serendipity kernel. No oc or uv. Is this normal for a battery to die so quickly?

ive been having the same problem(sudden change of battery levels). Wifi has been known to kill batteries on the captivate, or at least in my opinion. also, check if you have any background apps running that use up cpu resources. those kill your battery too.

depending on what you are doing.. if you watch movies thru it which requires intensive processor use then thats normal it really depends...it also eats up battery easily if backlight is set at the highest.

It's possible that you have a bad flash. You could try flashing back to stock, running master clear, and then reflashing Serendipity.

Actually, watching movies does not use a lot of processing power. On a recent flight I watched over 6 hours of movies and still had over 30% battery left when I landed. You can also adjust the backlight from within the movie player so it isn't too bright. Wifi is a huge drain, especially with the screen on while web surfing. Another drain is poor cell service since the phone will be continuously looking for signal. Having only 1-2 bars reception uses more power than having 4-5. When it drops below one bar repeatedly it uses even more. A 20% drop after an hour of web surfing on wifi is not that unusual.

yeah you have a point in there that's why I say it depends. when you only watch a you tube that has short buffering time it may not uses more processing power try watching movies from other site like webtv360 that constantly buffer until the end of the movie it will drain your battery fast sky high. maybe clearing dalvik cache and battery stats or even doing factory reset with his current rom will solve the issue as there might be some datas left lurking from previous rom after flashing that causes undesired effect with regards to battery drain. most of the time this will cure some icompatibility issues and force closes, doing this after flashing a new rom will save you more headache in the future.

Thanks for the help guys. I'll try to keep it off of wifi when im not using it and I've been putting it in airplane mode at points during he day. I just undervolted, so hopefully that'll help my battery.

Ahh, you didn't say streaming movies from a website. That's a double whammy since you are using the network or wifi and having to decode the stream on the fly. Very processor intensive, as you stated. I was referring to watching movies stored on my external SD card.
