No one is sure if the Apple Watch will be as successful as Apple wants it to be, but there is one feature that might make the device more attractive to potential buyers. It will have a battery-saving “Power Reserve” mode, where the watch only shows the time. All other functions will be cut off when the battery starts to run critically low. According to a report by MacRumors, this mode isn’t on any other Apple product as yet. Tim Cook said that the watch will last all day.
There will be a media event next week and the device will come out in April.
As reported last week, many of the originally planned sensors like blood pressure and stress were abandoned at least 18 months ago. The watch will have a movement sensor and a heart rate sensor, so it will still be usable as a fitness tracker. Reports say Apple is still working on those features, so it is possible we might see them in future versions.
