1 TrueDepth Saves Battery Life

Touch ID is completely missing from the iPhone X, and that’s okay. The TrueDepth system with Face ID is an advanced and extremely secure platform that’ll be used to unlock your device and make Apple Pay purchases, but it also powers Apple’s new Animoji. And since it’s smart enough to tell if you’re looking at it, it can automatically keep your screen lit when you’re reading or browsing the web, or better yet, save your battery life when you’re looking away.
