Apple is working hard on improving this, according to a re/code report, not happy with the current battery life.
During it’s early Wednesday morning launch this week, one aspect of the Apple Watch was not discussed – battery life. No specific or detailed comment on battery life during the onstage debut of the Apple Watch, or during the demos that followed. 9to5mac also pointed out that throughout the unveiling of the Apple Watch, there was no battery indicator present in the interface.
While the once-per-day charging would be about par with other smart watches in the market, Apple is working hard on extending the performance beyond a day.
Re/code asked Apple for confirmation on the expected battery life, but the spokeswoman Nat Kerris declined to provide any specific information, simply saying that Apple anticipates people will charge their Apple Watch nightly.
