How smart watch works without a battery

Samsung Gear S3: how smartwatch works without a battery. Is this it?

This is how a smartwatch that doesn't need a battery works.

Smartwatches come in many different shapes and sizes. The screens are big. The bands are decorative. Some have touchscreens and others don't. But they all have one thing in common: they need a battery to power them.

This is because, as smartphones have become ubiquitous in the last few years, smartwatches have suffered from a critical lack of relevance. That is starting to change with the new wearables being launched from Apple and others.

But no matter how smart the watch, the battery is always the first casualty. That's why Samsung has been thinking about the smartwatch battery conundrum for a long time and is finally ready to introduce a new way to power its flagship wearable: the Galaxy Gear S3.

Samsung Galaxy Gear S3 and the Gear S2 before it have kept a feature that is absolutely critical to powering a smartwatch: the small, removable battery.

At first glance the S3 looks identical to its predecessor, the Gear S2. But one key difference is the S3 has incorporated a small solid-state battery into its case that keeps the entire watch up and running for as long as 24 hours.

In addition to the battery, the watch has a 400MHz Exynos processor for the watch-to-watch connectivity and an X8 LTE modem for an overall smartwatch functionality. It runs Android Wear 2.0 with a revamped interface and the Samsung Pay mobile payment system.

The Gear S3 includes 4GB of storage so there's always music stored to listen to and a 5-megapixel camera so you can take selfies and capture video.

This is what a small, removable battery inside a smartwatch looks like. Samsung has added a battery into the Galaxy Gear S3.
