Inquiry on Implementing Energy Monitoring for iOS Apps and Calculating Energy Impact

Dear Apple Support Team,

I am reaching out to inquire about the implementation of an energy monitoring solution similar to Xcode's Energy Impact tool for iOS apps. Specifically, I would like to understand the following aspects to address issues like overheating and rapid battery drain:

How can we achieve monitoring and calculation of CPU, GPU, and network usage over a period of time within an app?

How is the current energy consumption level of an app determined? Additionally, how are the weights for various factors like CPU, GPU, network, and location usage allocated when calculating the overall energy impact?

Any guidance or resources you could provide regarding these questions would be greatly appreciated.

Thank you for your assistance.
