Apple Watch to have low energy ‘Power Reserve’ mode

The Apple Watch will have a “Power Reserve” feature that will let the watch run in low energy mode while only displaying the time, The New York Times reports. As of now, it’s unclear how the feature will be activated. Apple claims the watch’s battery will last a full day, requiring an overnight charge, and it’s unknown how much Power Reserve will affect this estimate. We’re likely to hear more details on this low-power mode — and any other Apple Watch features still yet to be announced — at Apple’s “Spring Forward” event, scheduled for Monday, March 9.
