Apple today announced that watchOS 9 will feature a new low-power mode on Apple Watch Series 4 and beyond. With Low Power Mode enabled, Apple Watch will get up to 36 hours of battery life per charge. When Apple Watch is in low-power mode, many core features will still be available, including activity tracking and fall detection, but some features, such as the always-on display and workout detection, will be disabled to reduce power consumption.
The new low-power mode in watchOS 9 is separate from the Apple Watch’s existing power reserve mode, which only displays the clock when enabled.
The low-power mode is just one of the new features that will be available on the new Apple Watch Series 8 and Apple Watch SE, which are available for pre-order starting today and will be available on September 16. other new features on the Apple Watch Series 8 include a temperature sensor focused on women’s health and car accident detection.
As for the new high-end Apple Watch Ultra, Apple said a new battery optimization feature will be introduced later this year that will give the device up to 60 hours of battery life per charge, and it sounds like this feature will be different from the low-powered model.
