Apple CEO Tim Cook, speaking at the first ever WSJD conference by The Wall Street Journal, discussed several topics that includes Apple Pay, Apple TV and more.

One of the topics that Cook discussed is the much-anticipated Apple Watch, with Cook saying that the company is "excited" on the device's upcoming launch.

Cook also said that he was impressed with the foresight of Jony Ive, Apple's senior vice president of design, and his team in understanding that "something you wear has to be personal," and that the device should not be "geeky."

Cook revealed information regarding the battery of the Apple Watch, which has previously been kept secret by Apple.

According to Cook, the users of the Apple Watch will find themselves using the device so much that the Apple Watch will have to be recharged daily. Cook, however, declined to specify an expected battery life for the device, stating that the company is still testing the smartwatch's usage and how long its battery will last on standard usage activities.

Even before the Apple Watch was unveiled and launched, several questions have already been posed on the battery of the device. Early reports, in fact, revealed that Apple was finding it challenging to make the battery of the smartwatch to last more than 24 hours.

While Apple initially targeted a battery life that will last up to four days, it seems that the Apple Watch will have a battery that will be similar to that of the iPhone, which usually requires charging daily for a standard user.

Cook's comments come in line with earlier reports that estimated the one-day battery life of the Apple Watch.

"There's a lot of new technology packed into Apple Watch and we think people will love using it throughout the day," said Apple spokeswoman Nat Kerris. "We anticipate that people will charge nightly, which is why we designed an innovative charging solution that combines our MagSafe technology and inductive charging."

The charger for the Apple Watch creates a magnetic field that attaches it to the back of the Apple Watch, through which the charger replenishes the smartwatch's battery. While the charging between the smartwatch and the charger is inductive charging, the charger still requires to be connected to a power outlet through an electrical cable.

Reports have also claimed that high-end models of the Apple Watch will come in luxury boxes that will also serve as the device's charging stand.

More details on the Apple Watch and its battery will likely be revealed as the official launch date of the device in early 2015 comes closer.
