Improvements to device network transitions and how your iPhone will prioritize sending messages over weak cellular networks are far more exciting to me than Siri AI. Here's why.

Apple said that iOS 27 includes advancements in device performance, including swifter network transitions. Typically, switching your iPhone between Wi-Fi and cellular networks requires opening the Control Center to manually turn off Wi-Fi. Doing so can reduce the risk of a connectivity lapse.

This connectivity lapse happens to me often when I'm on a hands-free phone call with my AirPods connected to my iPhone and trying to leave my house to run an errand. In my garage, my phone is still connected to my home Wi-Fi network, but as soon as I pull out of my driveway, my call drops because it loses Wi-Fi connection and doesn't default to cellular quickly enough. As a result, my call fails, and I have to redial.

Instead of proactively turning off my phone's Wi-Fi and making a call over cellular before leaving my house, more intuitive network transitions may minimize or eliminate this pain point for me.
