Most smartwatches struggle to last 24 hours on a single charge.

But the newly-releasedOnePlus Watch 2boasts a maximum 100-hour battery life.

One major change was the introduction of a dual-chipset architecture.

A developer-facing “hybrid interface” chooses when to utilize the AP or MCU.

This gives manufacturers and developers the ability to tailor battery optimizations to certain tasks.

Still, the Pixel Watch needs to be recharged every day.

This “expanded” hybrid interface is responsible for the OnePlus Watch 2’s extreme battery life.

This is in addition to the power-efficient health tracking capabilities that previously debuted on the Pixel Watch.

Google took the time to explain its “expanded” hybrid interface in aDevelopers Blogpost.

Frustratingly, this post makes no mention ofexistingsmartwatches.

However, Google says that “future devices” will leverage the hybrid interface for extreme battery life improvements.

Just know that the 100-hour landmark isn’t a guarantee.

The question, unfortunately, is whether Google or Samsung will take the plunge.
