The iPhone 16 models come in 6.1 and 6.7-inch sizes. Apple's iPhone 16 models features flat edges, an aerospace-grade aluminum enclosure, and a glass back that enables wireless charging Apple is using the same A15 chip that was in the iPhone 13 Pro models for the iPhone 16 models, but there is an updated internal design that allows for better thermal performance. The A18 chip offers a Hexa-core CPU, a 5-core GPU, and 16-core Neural Engine. The iPhone 16 models include a dual-core accelerometer that can measure up to 256Gs, and the accelerometer and a high dynamic range gyroscope power a Crash Detection feature that can contact emergency services if you're in a serious accident and can't reach your iPhone. Apple also uses other sensors to power this feature, so the barometer detects changes in cabin pressure, the GPS watches for speed changes, and the microphone can listen for car crash noises.
