The battery life of the Apple Watch may last through about 2.5 hours of heavy use, 3.5 hours of standard use, and between two and three days of standby or low-power use.
So says a news report today, citing sources close to the development of the Apple Watch.
Previously the only information we had on this was a statement by Apple chief Tim Cook that Watch users would need to charge the device every day.
Mark Gurman of 9to5Mac cites “people with knowledge of the Apple Watch’s development,” which, he says, provided the specific performance targets Apple wants to hit for the Apple Watch battery. The actual numbers may fall short of those targets, he adds.
Gurman’s sources says that Apple decided to use a powerful processor and a high quality screen in the Watch, both of which can soak up a lot of battery power. The processor will be close, performance-wise, to that of the A5 battery used in the current generation of iPod Touch, the report claims. And the Retina-class display can update at 60 frames per second.
The Watch will also run a stripped down version of iOS called “SkiHill,” Gurman writes.
