Apple Watch Ultra 4: Touch ID and the End of Wrist Passcodes

The rumor mill is already spinning for 2026, and the Apple Watch Ultra 4 looks set to be a game-changer. The star of the show is a secret feature dubbed AppleMesa, which aims to bring Touch ID right to your wrist. By integrating a fingerprint sensor into the Action Button, Apple could finally let us ditch those tiny on-screen passcodes for unlocking and Apple Pay. Beyond security, we are looking at a sleeker design that is up to 15 percent thinner, paired with a nearly bezel-less Tandem OLED display reaching a blinding 3500 nits. Under the hood, the 2-nanometer S11 chip promises massive efficiency, potentially stretching battery life to over three full days. With a beefed-up array of eight health sensors and expanded satellite features, the Ultra 4 is shaping up to be the ultimate power user's dream, assuming you can wait a couple of years for the upgrade.
