Samsung Galaxy Watch9 misses a key convenience feature with the Fold 8 Ultra
The Samsung Galaxy Watch9 brings updated health tracking, a refined design, and the latest wearable features, but one everyday limitation continues to stand out: it cannot charge wirelessly on the back of the Galaxy Fold 8 Ultra using Wireless PowerShare.
For users who rely on Samsung’s ecosystem, this is a frustrating gap. Wireless PowerShare is designed to make life easier by allowing a Galaxy phone to share battery power with accessories like earbuds, smartwatches, and other compatible devices. In theory, it should be the perfect backup when your smartwatch battery is running low and you are away from a charger. In practice, Galaxy Watch9 owners do not get that benefit with the Fold 8 Ultra.
The issue is not entirely new. This charging incompatibility started with the Galaxy Watch 7 generation, largely because of changes to the watch’s internal design. Samsung’s newer BioActive sensor increased the distance between the charging coil and the back of the watch case. That extra space makes it difficult for the phone’s wireless charging system to create a reliable connection.
From a technical standpoint, there is a reason why many wireless charging accessories do not work universally across every device. Charging standards, coil alignment, heat management, and power delivery all matter. However, the disappointment here comes from the fact that both devices belong to Samsung’s own premium lineup. When a flagship Galaxy smartphone cannot charge a flagship Galaxy smartwatch, the ecosystem feels less complete than it should.
This matters even more because battery life remains one of the more noticeable weaknesses of the Galaxy Watch9. Smartwatches are meant to be worn all day for notifications, health tracking, workouts, sleep monitoring, and navigation. If the battery runs out while traveling, commuting, hiking, or spending a long day away from home, the watch loses much of its purpose. Most users are unlikely to carry a dedicated charging puck everywhere they go, which makes Wireless PowerShare especially useful as an emergency feature.
The Fold 8 Ultra has the size, battery capacity, and premium positioning to serve as a practical power backup for smaller accessories. Being able to place the Galaxy Watch9 on the back of the phone for a quick top-up would add real everyday value. Instead, users are left with a feature that works for some devices but not one of the most important wearables in Samsung’s own product family.
Samsung has built a strong Galaxy ecosystem around phones, watches, tablets, and earbuds. The appeal is convenience: devices that connect quickly, share data smoothly, and support each other when needed. The lack of Wireless PowerShare support for the Galaxy Watch9 weakens that experience.
For future Galaxy Watch models, restoring compatibility with reverse wireless charging should be a priority. Even if charging speeds remain slow, having the option available could prevent a dead smartwatch at the worst possible moment. A simple emergency top-up from a Galaxy phone would make the Galaxy Watch feel more reliable and better integrated into Samsung’s premium ecosystem.
The Galaxy Watch9 is still a capable smartwatch, but this missing feature is a reminder that hardware improvements should not come at the cost of practical daily convenience. For many users, a smartwatch that can be rescued by their phone’s battery is not just a bonus. It is exactly the kind of smart ecosystem feature they expect from high-end Samsung devices.
