The Galaxy Watch 7 and Ultra include new features such as improved health tracking with a redesigned BioActive sensor, Galaxy AI integration powering Energy Score and Wellness Tips, sleep apnea detection technology, and a Quick Button for various inputs during a workout. The Galaxy Watch Ultra also has an emergency siren and enhanced durability with a titanium body.

The Galaxy Watch 7 and Ultra don't support Wireless PowerShare due to the redesigned BioActive sensor and back glass shape, which improves health and fitness tracking accuracy3. However, this new shape conflicts with and prevents Wireless PowerShare from working, so Samsung decided to drop support for it in these new smartwatches.

Wireless PowerShare technology is a feature in Samsung Galaxy smartphones that allows users to turn their devices into wireless power banks, enabling them to charge other devices such as Galaxy Watches, earbuds, and smartphones2. The technology uses Qi wireless charging, and while not the most efficient method, it provides a convenient way to charge devices when traditional charging methods are unavailable.
