YotaPhone 2

With their large, power-hungry displays and small batteries, most smartphones struggle to run for more than a day on one charge. The Android-running YotaPhone 2 takes a different route to extending battery life, instead combining both a traditional LCD screen with a power-sipping Electronic Paper Display, or EPD, on the flip side. This touchscreen-capable EPD makes possible 5 days of reading time on a charge and also doubles as a customizable dashboard to show you your email, music, calendar, stocks, twitter feed, and more at a quick glance. YotaPhone 2 also comes unlocked, includes all expected modern connectivity and features (plus GLONASS), and sports durable Corning Gorilla Glass 3 on both sides.
