"Running Charles on your iOS device means you no longer need to fiddle with WiFi network proxy settings. It also means that you can capture and measure network traffic that goes over the Mobile / Cellular data network.
Measuring networking performance over Mobile data is especially important for your mobile apps (as that is how a lot of users experience your app), and it can reveal large or slow requests, as well as opportunities to increase perceived performance by parallelising network calls."
AFAIK before this you could only inspect traffic over WiFi connections since you had to set the proxy address via WiFi network settings.
