ASUS Pushing For One-Week Battery Life In Its Future Smartwatches

One of the challenges smartwatch designers face is that of battery life. Understanding that users don't want to be bothered with frequent recharges, companies are devoting a lot of time and R&D into figuring out how to extend battery life. Looking to up the ante, ASUS over the weekend hinted that its next smartwatch might be able to run for up to seven days before needing a recharge.

That's in stark contrast to Apple's goal, which is to get its Apple Watch to last all of 19 hours before needing a charge. Active use would be far shorter -- Apple is aiming for 2.5 hours to 4 hours when running an application nonstop.


How will ASUS be able to offer dramatically improved battery life compared to Apple? The trick is in using a simplified chipset and mobile operating system designs..

"The ZenWatch is defined by us as a companion of a smartphone, and we think it still has a lot of room for improvement," ASUS chairman Jonney Shih recently told reporters. "As a companion device, its central processing unit and operating system should be more simplified than the current version, so that I can use it for up to seven days on one charge, rather than for just two days."

ASUS is referring to its first generation ZenWatch that it launched in Taiwan a month ago. It sports a 1.63-inch AMOLED touchscreen display, curved cover glass, Qualcomm Snapdragon 400 processor clocked at 1.2GHz, 512MB of RAM, 4GB of internal memory, and a battery life of up to two days.
