There's no way around the daily charging of smartphones, as those devices simply draw too much power to be able to function for much longer than a day at a time (especially for heavy users), so the TicWatch Pro from Mobvoi is aiming to reduce the amount of charging for another device. The smartwatch uses a clever display layout to draw far less power than competitors, allowing to to run for longer on a single charge.
The trick with the TicWatch Pro is that it makes use of two screens. While one might think that two screens would lead to more powering being used, the opposite is in fact true. The outermost screen is actually a transparent FSTN LCD display, like the kind used on cheap digital watches.
