Re: bb bold 9790 heating issue



It's common for smartphones to heat up. It's due to the Core(s).


If you had 1 Core you device would get hotter. As the Core would be doing all the work.


Dual Core (2) shares the work load and the device doesn't get as hot but still gets warm depending on usage.
