How long will the Apple Watch’s battery last? An entire day, according to The Telegraph, who recently interviewed Apple CEO Tim Cook. The battery life has been a subject of speculation since the Apple Watch was announced in September, with some saying it could be as short as 2.5 hours. Cook also told The Telegraph that the Apple Watch would charge more quickly than the iPhone. NBC News reached out to Apple but the company has not responded. The gadget will also be able to unlock some car doors, The Telegraph reported, possibly referring to already announced apps from companies like BMW. Cook also told The Telegraph that the watch would let people buy things with Apple Pay. The company is expected to launch the Apple Watch during an event on March 9.
