[Q] Does N1 heat up a lot when using GPS? - Nexus One Q&A, Help & Troubleshooting

So, I took my Nexus One for a spin using Google Turn-By-Turn navigation and it was like a 25 minute drive and when I got home, the phone was really hot, to the point where i was afraid this thing may be close to being fried on the inside. The touch screen wasn't working properly (not responding to touch and being very inaccurate than normal). I left it on the desk and after 5 minutes it cooled down again and was fine.
What the heck is wrong? is it cause I kept it on the dash board against the dials, that area was kind of warm but nothing to heat up the phone that much, should I be using a cradle or something?
Its a fully stock Nexus with 2.2.1 FRG83D, not rooted and no other apps running. Same thing happened with the free program MapDroyd, so it isn't Google Navigation only issue either.

I don't use GPS much, but when I first got it, I did and it was fine. After about 9 months though its started getting pretty warm, within minutes of using 3g, roughly 38degrees celcius (about 100 fahrenheit), but apparently it's been tested and works fine up to 57 celcius (134 fahrenheit) or something like that.

it's not the gps .. it's the turn by turn navi.. it uses massive amounts of CPU that is what heats up

It is a number of factors, including the previously stated turn by turn navi. You also have the screen on permanently, plus at least where i live, anything in a car not in an air conditioning stream is going to heat up a lot.
I suggest getting a setcpu widget or some other temperature monitoring widget. I also set my cpu to underclock when it gets above 48 degrees C.

Heavy CPU usage, GPS probably generates some amount of heat, but mainly it also adds to the battery draw which adds heat. Screen is on, and you're possibly also downloading quite a lot of data unless your maps are entirely offline.
Also, your phone might be sitting in the sunlight, or in the winter might have the vents blowing over it.
So just the GPS? Not really. Run GPSTest sitting on your desk. You'll see significant battery usage (probably adds 120mAh to what it'd normally use) but it won't get hot.

Yeah, turn by turn navigation does seem to heat it up a lot, even when caching the map offline entirely on a Wifi network beforehand. My phone isn't rooted, but maybe I'll root it and use setCPU thanks.

Will actually heat up more if plugged in. Although mine never gets past 115 or so and this is with GPS and music playing.

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??

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.

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
