Temperature detection

[Guest dilaroid]

just wondering. how does android check battery and processor temperatur (esecially at battery) ? is there a sensor inside battery ? or outside battery ?

thanks

A sensor inside the battery is the normal way of doing it which is why the battery has 3 contacts, gnd, positive and some form of 1 wire data. We can't easily tell quite what the pulse does as the battery driver just queries the ARM9 so we can't see the low level code. The other temperature sensor is part of the akm8973 compass

Every battery has a temperature sensor. It is needed to estimate the battery percentage as accurate as possible, because the voltage changes if the temperature changes.
