The first official day of CES 2018 is all wrapped up, and things were quite busy at the Engadget CES stage. Along with people like GoPro CEO Nick Woodman joining us at the show, we had other companies from the tech industry there as well. In one of our chats, we talked to executives from Fitbit, Fossil and Samsung about where they see wearables going in 2018, and what will be the biggest challenges ahead for the category. A main point of emphasis was that moving battery life from days to months is key to the success of wearables in the long term, which may seem obvious but will continue to be a main topic of discussion until there's a major breakthrough.
