Introduction Working with batteries on iOS devices for large applications has always been tricky. The amount of energy consumed by the screen, location services, network calls, processing, background tasks, etc., is significant. From a developer’s perspective, it seems complicated, but Xcode provides tools to address this problem. To find the issue, you need to open Xcode and go to the Debug Navigator. In the Debug Navigator, you will see the Energy Impact gauge. In the histogram, blue indicates good performance, while red indicates overhead. Based on this information, you can analyze the overhead and resolve potential issues by utilizing Instruments such as Network, Location, CPU Profile, etc. For each case, Xcode provides instruments that allow you to dive deeper and understand what is happening in detail. ...
