My N900 rapidly overheating...
 

can anyone help me because my n900 keeps on overheating..

Re: My N900 rapidly overheating...
 

Check what applications that are running and more so the cpu usage then you will have your answer.

Re: My N900 rapidly overheating...
 

im use web browsing only..

Re: My N900 rapidly overheating...
 

Define "over" heating; it's normal for the device to feel warm to the touch when fast charging or heavily discharging, but, you shouldn't be able to cook on it. What temperatures are you seeing that you consider excessive, and how are you measuring them?

As a guide, the battery die temperature on my N900 sits just below 30 degrees Celsius when it's not doing very much, and peaks at about 43 degrees when I'm using it heavily (~500mA current drain), and those numbers aren't cause for concern. If you're over about 50 degrees, that is overheating...

Re: My N900 rapidly overheating...
 

Install Conky or something like it and you will see why it is getting hot, it is down to cpu usage 99.99% certain of that unless your charging all the time and you never indicated that.

@dignified
If you are browsing using OpenVPN your phone will be hotter than usual. I tried that yesterday.

Re: My N900 rapidly overheating...
 

does savecpu help? does conky have a setting? sorry ive never tried that aplication yet

Re: My N900 rapidly overheating...
 

bro vetsin.. im using supersurf... i dont know but my phone keep on heating.. i dont what is the problem.. openvpn didnt connect everytym im using it

Re: My N900 rapidly overheating...
 

Install Conky, which is aslike Task Manager on WIndows, which shows Processes running and CPU usage, install Conky and upload few screenshots of it, whn u feel the N900 is overheating..

Re: My N900 rapidly overheating...
 

this is the screenshot

Re: My N900 rapidly overheating...
 

was N900 overheating whn u took the screenshot, coz it doesn't seem like..

Re: My N900 rapidly overheating...
 

yes.. its so hot in my hand..

Re: My N900 rapidly overheating...
 

Whn did it start overheating? for example about from yesterday evening onwards or after installin "so-so" application/software etc...

Re: My N900 rapidly overheating...
 

Very much like my darling ;) sorry could not resist :D

Re: My N900 rapidly overheating...
 

it start when i own it the phone.. i tried reflashing but after that.. is the same thing happen.. always heating..

Re: My N900 rapidly overheating...
 

so u are saying that the phone has never been in a cooler temperature stage from the day 1 u had it. o0

Re: My N900 rapidly overheating...
 

nope.. when i didnt use... it will low temperature.. when i use on browsing and gaming or charging,,it becomes hot

Re: My N900 rapidly overheating...
 

The screenshot with conky is inconclusive. In fact some of the outputs from it aren't really useful.

You might want to check using top as root to see if there's any kernel threads (they are the ones with square brackets around them, e.g. [softirq]) are sitting on top of the processes.

Also has this device been overclocked before? is this device brand new or second hand? If its second hand have you asked the seller if he/she has done any overclocking on the device? which firmware are you using?

Re: My N900 rapidly overheating...
 

im overclocking sometimes but i return to default.. this is the what it shows in terminal when i top

Re: My N900 rapidly overheating...
 

have u tried this,

Re: My N900 rapidly overheating...
 

sir that tweak makes my phone reboot...

Re: My N900 rapidly overheating...
 

You haven't really answered my other questions. Though I guess previous overclocking attempts (regardless if failed or successful) may have potentially caused hardware damage with the device.

The screenshot from top isn't helpful either, you need to be the one viewing it not us. There should be at least a process under CPU% somewhere that is causing the device to overheat. At least with the CPU being maxxed out it will use its maximum specified frequency.

Also with conky running, you can see on where it says Load1 avg. DIO. Mem. Those are also some of the useful fields when you have conky running for at least 5 minutes.

The load average is over 5 minute intervals, its collected from uptime command, the DIO is most likely Dynamic Input/Output and Mem is obviously memory usage. If any of those are high, notably load average or DIO it means that there is a process/kernel thread somewhere that is hanging up or some process that is thrashing I/O.

An output of your dmesg (into pastebin) along with maemo-list-user-packages would be handy.

Re: My N900 rapidly overheating...
 

im the owner sir.. and sometymes i success overclocking and sometimes failed becauseit it reboot itselt when i aplied the latest batterypatch... the only one problem is drained battery and overheating when browsing.. but when i used it for music or movies it doesnt heat..

Re: My N900 rapidly overheating...
 

any patch or command to avoid overheating on browing and gaming?

Re: My N900 rapidly overheating...
 

I think your definition of overheating could well be a normal situation as the cpu will go 100% on any computer when browsing, the other factor could be the battery losing the ability to hold a charge and you can only check that by replacing the battery.

Gaming will for sure make the cpu high in usage and could very well be why your device is getting hot but i still say you need to check the battery first and take into consideration what your actually doing on it to overheat, so far you have picked the 2 most common high cpu usage as in gaming and browsing.

Re: My N900 rapidly overheating...
 

ahm okay.. it is affect to our phone?

Re: My N900 rapidly overheating...
 

Yes i would certainly say so, it is because you not know anyone else with a N900, they DO get very warm when being used.

Re: My N900 rapidly overheating...
 

You guys asked way too advanced already without asking the basics first....

Answer my question first before theirs.

1. When browsing what sites do you open? Does it require flash player to load? How much windows are usually opened when you are browsing? Is it some basic wap sites or some of the xhtml high loading sites(detailed sites)?

2. When playing games, what games do you play with your device if it's overheating? Is it some of our roguelike games? or preenv? or some of the GLES games ported to maemo? or even some of the emulators available here(PSX, GBA, nes, snes, amiga, sega etc.)?

Re: My N900 rapidly overheating...
 

maybe its the weather, n900 gets hot sometimes, especially with apps open, on a cold weather its gotta feel warm, but unless its burning causin 1 degree burns its usually that way.

Re: My N900 rapidly overheating...
 

Could you please install qcpufreq (or I don't know if health check reports temperatures) and post the temperatures? Mine is 36,3C and it's been idle and normally clocked. It gets up to 47 some times under heavy usage and overclocking to 1000.

Notice that qcpufreq reports tenfold temp under certain configurations so don't panic if you see 380C :)

Re: My N900 rapidly overheating...
 

my temperature ups to 43 celcius using default config.. so hot in hand

Re: My N900 rapidly overheating...
 

Oh, cool - it's only taken 27 posts to answer the question I asked back in post #4, and the answer seems to be that your N900 is not overheating in the slightest, but operating normally. Can I suggest if still you want it to run cooler than that, try using the device less? This will have the added bonus that you run into fewer problems with it.

Pardon the sarcasm, but, really... what do you want us to say?

Re: My N900 rapidly overheating...
 

Hi guys,

Im hving N900 fr the past 1nd hlf yrs.....
Recently im also suffering frm same probs... bt mine is kind f severe

My boy's history goes like this...

I got it frm ma frnd whu usd it fr 5 months.... No ovr clocking nothing; he didnt evn knw hw to instll aps frm repos....:rolleyes: So it ws good as brand new....

I have instld nitdroid, done overclocking and usually used it in 850 all the time.....
So good so fr....
One good day i pluged my 900 into usb port in my offic which ws disabld. It suddenly turned off and none of my tries booted the phone up

- so I changd the battery and evrything ws bak in trak


Going forward i changed my swappiness to 30 (2 months bak) and the device hd pretty good responsiveness aftr that
Then one day i left the phone for overnight charging and at morning wen i woke up it ws so hot (around 45.... ) .
Also instead of 100% the battery ws shwing 80% charge while plugged in
Within 2 hours battery drained out....

Frm then on the same symptom prevails...
I havent done any particular app installation or updates during this time
The temp is as follows
Sitting idle :36-40
I tried to play POP (port) :50:eek:
gprs :45-48
gprs and charging :above 50

I ws in an AC room for a while and temp dropped to 27.
on playing POP it shooted back to 50.

(All the temp is as of frm QCPU freq)

I tried another battery and things are all the same..
I just dnt wnt to giv it to service centers since im having a lot of tweaks in my baby :(

Which language you are using? (Wh langug y re usn?)

Wt th fk...???

Re: My N900 rapidly overheating...
 

Guys, sincerely sorry for any mistakes....
When i went through the thread people were asking lot of questions in detail.... thats why explained so much.....
Will you guys help.....

Re: My N900 rapidly overheating...
 

I think they didn't take it as an issue for your explaining it in detail...it was the way your post was written. :)

Re: My N900 rapidly overheating...
 

Ok,Honest mistake.....
What about the issue.... Is it a hardware problem or shall i try a reflash?? :rolleyes:

Re: My N900 rapidly overheating...
 

Firstly do bear in mind the "temp" is the battery sensor temp.
The actual internals maybe hotter.

Have you tested for processes with top?
Have you tested for CPU usage with powertop?
Have you tried the device with standard clock speeds 250-600?

Re: My N900 rapidly overheating...
 

Yes i was aware of that, It is the battery which is heating up the device.., I persume.....

I tried top , none of the processes are eating up the cpu (I have to check while the phone is idle, right?)...
In fact i have the cpu app that shows usage near Menu button,
-Even it is not shooting up


I didnt; will try that and post...

Yes the whole temp readings i just got in normal clock speed only...
When iam overclocking the rate of temp ascend is considerably increased
