June 13, 2025

Speaking on Saturday, Jonney Shih, chairman ofAsus, stated that this would be the year the company focuses on pushing its low-costZenFone smartphone rangeto the global market. He also let slip a few thoughts about the company’s successor to the excellentZenWatch.

Shih hinted that ASUS’ next smartwatch could be designed to last up to seven days on a single charge of its battery, a notable improvement over the current ZenWatch’s maximum of two days.

This battery saving likely won’t just come from a larger battery capacity, ASUS may be planning to opt for a more energy efficient, lower performance processor next time and might be prepared to cut down or even ditch Android Wear in favour of a more efficient, simplified operating system. Exact hardware details weren’t given, but ASUS looks to want to further differentiate itself from other high-end smartwatches by offering additional battery life.

With ASUS talking about a simplified OS, Samsung looking to push Tizen more heavily this year and LG rumored to be preparing its ownWebOS powered smartwatch, Google’s Android Wear platform could end up being sidelined by custom built smartwatch operating systems in the future.

Back at the launch of the ASUS ZenWatch last year, Shen also let slip that the second-generation ZenWatch is planned for Q3 2015. The smartwatch is said to feature SIM-card funcationality, allowing it to take calls without being tethered to a smartphone. ASUS also has plans for two lost-cost “wrist-band like” devices targeted at the health and fitness market.
