Apple has announced its very first 5G iPhones: the iPhone 12, iPhone 12 Mini, iPhone 12 Pro and iPhone 12 Pro Max. They range in price from $729 to well north of $1,100, but — as Apple proudly announced during the press conference — even the Mini offers access to speedy millimeter-wave (mmWave) 5G networks.
As it turns out, that’s why each new iPhone features this conspicuous groove along the right edge. It’s a special window for mmWave signals, and it appears to be designed so users can visibly see it and perhaps avoid holding it there for maximum signal strength.
Can confirm that this little thing on the side of the new iPhone is a mmWave antenna window! pic.twitter.com/Gjdj6SfWGy
