The Apple Watch Series 8 has a load of new health and safety features, including car crash detection. The updated specs include two new motion sensors in the form of a three-axis gyroscope and a high G-force accelerometer that can pick up to 256 G’s. For reference, fighter pilots handle up to eight or nine G’s max.
The Series 8 also comes with menstrual cycle tracking and a new and improved temperature sensor that can accurately estimate ovulation. One temperature sensor rests against your skin, while the other is at the edge of the display. These stats give you an estimate of ovulation. Of course, all of this information is protected through secure encryption.
The Apple Watch Series 8 still has its 18-hour battery life, but a new Low Power Mode can give you up to 36 hours of battery life by shutting off the always-on display and the workout tracking feature.
