Choosing the right iPhone 16 cover involves more than just protection and style—signal strength can also be affected depending on the material. A metal phone cases may interfere with your phone's ability to receive strong signals, especially if the cover is not designed with signal-friendly technology. While metal provides superior protection and a premium look, an iPhone 16 cover made entirely of metal can sometimes block or weaken cellular, Wi-Fi, or GPS signals. That’s why it’s important to select an iPhone 16 cover with built-in signal channels or hybrid designs that include non-metallic areas to support connectivity.
