Apple Watch battery could last as little as 2.5 hours

The Apple Watch battery will provide between 2.5 and 3.5 hours of active usage according to a report published by Apple rumour publication 9to5Mac. This number will depend on how processor-intensive an application running on the Apple Watch is, and result in a combined battery life of 19 hours, taking into account the time the Watch is actively used, and the time it is on standby.

The report also suggests that the Apple Watch can only display a clock face for three hours straight. As such, the Apple Watch will turn off its screen when the device isn't actively used or displaying new notifications. When used in fitness tracking mode, the Watch's battery should last around 4 hours, and if left on standby, between two to three days.

While the provided figures may be smaller than expected, 9to5Mac suggests that most users will passively wear the Apple Watch, only interacting with it in short bursts throughout a day.

9to5Mac's sources told the publication that a short battery life was a contributing factor for Apple pushing back the Watch's launch from late 2014 to early 2015. It is expected that the Apple Watch will ship in March.

Tim Cook last year said the Apple Watch will be a device that requires a nightly charge.
