Why Some Galaxy Phones Fail to Charge Samsung Watches

Samsung’s newest smartwatches cannot charge from a phone. The Galaxy Watch 7 and Galaxy Watch Ultra lack reverse wireless charging support. This feature was available on some older models. The change is a permanent design decision.

Samsung confirmed the shift to multiple tech outlets. The removal is due to hardware improvements. These upgrades enhance health tracking but disable phone-based charging.

Design Upgrades Halt Reverse Charging

The new BioActive Sensor is the main reason. Samsung redesigned this crucial health component. It now offers better accuracy for heart rate and sleep tracking.

This improved sensor array changes the watch’s back panel. The new design disrupts the energy transfer needed for reverse charging. According to reports, the technology is simply no longer compatible.

Strap Design Presents a Practical Problem

Bands also caused issues on previous models. The Galaxy Watch 5 Pro technically supported the feature. However, its large strap often blocked the connection.

Users frequently had to remove the strap to charge. This made the process inconvenient for daily use. Newer watches continue this band design, making the feature impractical even if it worked.

Trade-Off: Niche Feature for Core Improvements

Samsung prioritized core health functions. The company decided advanced fitness tracking was more valuable. Reverse charging was rarely used as a primary power source.

This trade-off benefits the majority of users. They gain more reliable health data and new metrics. They lose a backup charging method that few relied on regularly.

The removal of Wireless PowerShare for the latest Samsung Galaxy Watch models highlights a clear choice. Samsung favored advanced health technology over a niche convenience feature. This decision ultimately strengthens the core purpose of a modern smartwatch.
