Most Wear OS-based smartwatches require charging after a single day, but Mobvoi is attempting to buck the trend with its new $249 TicWatch Pro, which it claims can last between five to thirty days on a single charge, thanks to a layered display and a special power-saving mode.

The TicWatch Pro’s screen, housed in a large 45mm case, includes an OLED display, as well as a more basic Film compensated Super Twisted Nematic (FSTN) LCD display.
