Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

you are not alone, i have been experiencing this too, my n900 has been heating it feels warm. while before it was cool, not sure whats going on......

also the battery for some reason seems to finish faster than before, maybe its all the widgets that i have, not sure, anyone know whats going on ?

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

mine gets hot whenever i skype, pre and post 1.2

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Mine has been, as well. CPU and Battery usage are far above the usual. Although I've installed quite a bit of stuff from -testing and -devel. Will investigate.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Exactly the same problem.

after using n900 for 5 minutes, it become very warm.

the keyboard, the back pack (battery) is just hot

then put it away for 20 minutes, it become cool.

I use Conky to check and all is normal.

CPU usage is only 2 percent.

Is it related to the summer ?

I used PR1.2 before and no such problem.

I had just reflashed ROM and EMMC and only a few apps installed now. The problem come yesterday.

I think it is not OS related.

This thread should be put on N900 section.
can some guy from NOKIA take a look on this issue ?

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

I think it might be the summer. I had no problems with PR1.2 until recently. My N800 has (and had, in previous years) the same behavior.

Thread Moved to Nokia N900.

I think it's normal. If you want Nokia to look into it, don't post it here. This isn't a Nokia support forum, it's a community forum, so less than a handful of Nokia employees visit. Go to the Nokia forums: Nokia Europe or Nokia USA and post it there.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Hmm. Mine getting warmer too, on usage that's it. If left idle, still cold same as before. Did a ROM and eMMC reflash, everything get smoother and more fluid too! But the battery are still the same bad, after PR 1.2 firmware update... I see some people get the same problem as me, while some others get the opposite...

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

The reason is the Fourier's law of heat. The flow rate of energy is proportional to the gradient of temperature. No gradient, no flow.
It's summer!

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Dunno about heat, but mine is certainly 'hawt'er. :D

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Mine is getting really hot while thetering trough the cable and while navigating (sygic). And when I say hot, I mean hot.The first time I felt it I thought my phone would explode.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

I had an incident this morning. Last night I closed everything, set my alarm and plugged the phone to the charger but not only did the alarm not activate this morning but I woke up to a completely blank screen and the device so hot that I couldn't hold it for more than a few seconds... This never happened before... It seems to be working fine now but that was quite scary.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Unfortunately I experienced the same probs. The N900 is getting really hot from time to time. It wasn´t like this before the update :mad:

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Never felt any heat from it, no matter what firmware.

Do you overclock it?

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

Mine was absolutely boiling today. Its never done that before.

My battery had drained as well in just a couple of hours. I booted it and charged it and although it wasn't hot anymore it was really acting up. Rebooted it again and its been fine since.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

I am having battery problems since i transfered some movies and pics,i run conky and it shows"bridge_work-que " using 80percent of cpu,sometimes 96,how to solve this problem?
thanks

Look into this bug 10412 - https://bugs.maemo.org/show_bug.cgi?id=10412

It seems that hildon-desktop now may go crazy and polls some file descriptors instead of wait some input.

Please vote for this bug 10412 for faster resolution.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

It's happening the same to me. I've found (using top on X Terminal) that browserd proccess is taking as much as 97% of CPU usage. That explains the hot temperature.
If I open a browser page the CPU use decreases to 4-5%. Then if I close the browser the CPU is up again.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

yes since PR 1.2 upgrade my phone gets really heated and I did not experience this at all before the update.

But since after update it always tries to connect to my wifi...and my internet connection requires further login by entering user name and password. So just by connecting to the wifi its not actually connected to the net unless I enter username and password. So for that reason since it only connected to wifi... it keeps trying to connect to skype and gtalk constantly and thus heats up the phone.

However, when I disable the wifi it doesn't heats up and battery remains longer than a day.

I was thinking may be I overclock the phone in the range of 125Mhz - 850Mhz... it should resolve the problem cuz when idle I expect it to stay at 125Mhz while when in use the speed should vary.

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

I just had left my N900 on my desk for about two hours. When I came back this little computer was hot like hell and the battery was empty. Fortunately I´ve got a second fully charged battery so I could boot the system. It seems to work just fine now. But what the f... had happened during the last two hours?

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

some of the first possible reasons i can think of:

1.) u have installed the "Recaller" and accidently hit its button on the N900 desktop... then it starts recording system sounds (or phone calls)... it can get hot if its run 2 hours straight...

2.) u made a phone call and forgot to hang up...

3.) u accidently opened the camera lid, and the camera app was still running in the background...

4.) a webbrowser was left open with cpu intensive "flash content"...

5.) the phone lost GSM/UMTS coverage and activelly tried to trace a new cell tower...

6.) u left some other software running in the background thats cpu/gpu intensive... (or maybe u accidently tapped the screen and started a application right before u used the "screen lock" function.

7.) or... if its none of the above - maybe its just simply a bug in Maemo5 that for some reason hogged the system.

good luck with the investigation ;)

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

btw folks... could it be that the N900 is sensitive to dust / dirt / sweat?

im also experiencing a hotter N900 nowadays... i got the N900 just a few days before PR1.2 was released, and i did NOT experience any additional heat after installing PR1.2...

however - a few months after installing PR1.2 i started to notice that the N900 started to get hotter and hotter during intensive use...
now ive had the N900 for 6 months and its getting remarkably more hot during 3D gaming, than it did when it was brand new...

i think the reason is the same as with desktop- / laptop computers... dust and condensed moisture / fat / sweat / dirt...

...unfortunatly its difficult to clean the N900 ...as usual with cellphones, all chips inside the N900 are covered with metal housing plates (probably shields humans from electronic radiation), but maybe its enough to clean the surroundings

Maybe 1 / 4 / 5 / 7 or maybe not :rolleyes:

Re: Has anyone else's N900 become significantly hotter after the PR 1.2 update?
 

PR 1.3 and voila no heat problem anymore. Thanks Nokia.
