Understanding CPU usage in iPhone 15 Pro series

Hello everyone,

During the development of our company's web application, I found something intriguing in the CPU usage and load conditions on the iPhone 15 Pro series. While monitoring these statistics from the Safari console, the CPU usage sometimes exceeded 100% and even rose to a maximum of 190%.

I'm curious about a couple of things:

1.What exactly is the baseline for 100% CPU usage?

2.What state does the device enter when it starts exceeding 100% CPU usage? For instance, is it utilizing the use rate normally allocated to Safari plus some extra reserve?

The process used for checking the load is as follows:

1.Connect the iPhone device with MacBook via a USB Cable.

2.To test for a web application, I executed it on the iPhone Safari browser.

3.While it's running, I measured the CPU load on the MacBook, using Safari to obtain the console of the iPhone's browser.

Any help in understanding this would be highly appreciated.

Thank you.

I believe that the percentage is based on one cpu being fully utilized. 190% would mean that two cpu's are being utilized.
