Hi at all,
Using the nexus 5 I have a 70 Celsius cpu temperature while playing a 3D game and browsing Currents.. Is this ok for the phone? Or its dangerous?

What is the maximum temperature of the cpu without damaging the phone?

Thanks for your help and sorry for my English, any correction is welcome!

Hi,

70C for the CPU temp is "normal" when you paly a game. Remember that we have a quadcore at 2,26Ghz without any cooling system...

In any case there is the thermal trottling to prevent any damage. According to the CPU temp (and also the battery temp) the CPU freq decreases automatically.

Also there is an hotplug routine according to the temp (cores offline at a certain temp).

The last "ultimate" thermal protection is the shutdown at something like 100C (according to the thermal-engine.conf file it "should" be above 100C, but...).

So no worries there is a protection and your CPU temp is not abnormal.

The phone will not let itself achieve a dangerous level unless you have modified the kernel to tell it not to thermal throttle at 70.

the frequency throttle temperature is 70 celcius the suspend temp is 65 and core throttle is 80

Thank you!
I should have guessed that there is a system to prevent "overboiling"..
PS: I used the search button with" temp" and "temperature" but I haven't find thread.. I guess I don't know how to use the search button
Thanks for your time
