Phone gets heated when running my application

Question

When I use my application for awhile, I have noticed that the device gets hot. Apple devices usually get hot when running applications, so I want to know if there's a method to check if I have done something wrong in my application.

I don't think the Allocations tool in Instruments could help me diagnose the problem.

Answer 1

Instruments can definitely help you solve this. Your device gets hot as a direct result of intense CPU activity, which Instruments can track and show you your CPU usage and memory allocations.
