After The Apple Watch Dies, This Is What Happens
Based on Apple’s “Spring Forward” it has been suggested that the Apple Watch battery life can last up to 18 hours. Apple has come up with an interesting feature for such times that the Apple Watch battery dies is that the Apple Watch goes into Power Reserve. This “Power Reserve” feature makes it seem like when the device is placed into this mode, all functionality of the Apple Watch will be eliminated. This would include syncing with the iPhone for notifications and data, and serves up the most important functionality of a watch, instead.
Recommended: Apple Watch battery can be replaced
In fact, if you should only check the time on the device and do nothing else, the device should be good enough to last up to five days, according to Apple’s official estimates.
The Apple Watch goes on pre-order beginning April 10 and is scheduled to ship in the United States, Australia, Canada, China, France, Germany, Hong Kong, Japan and United Kingdom on April 24.
