Samsung plans to introduce a new smartwatch this week to compete with the popular Apple Watch and others entering the emerging market. The South Korean company is expected to unveil its new round-faced Gear S2 at the IFA trade show in Berlin tomorrow. According to The Wall Street Journal, the watch will “come in two styles: a sporty flagship version and a more understated version dubbed the Gear S2 Classic,” both featuring “3G connectivity, which means they can also work as a standalone phone — something most current smartwatches can’t do.” Samsung also says its models will tout battery life of 2-3 days, more than most other current smartwatches.
