Samsung Galaxy Watch 9: Why are Users Resorting to Extreme Measures for Charging? (2026)

The Galaxy Watch 9 and Watch Ultra 2, Samsung's latest wearable devices, have caused excitement among enthusiasts, but a growing number of early adopters are facing a frustrating issue: slow charging speeds. Despite Samsung's claims of quick top-ups, users are reporting charging times that far exceed the advertised 80-90 minutes. This has led to a heated discussion on Reddit and official forums, with users sharing their experiences and finding creative solutions.

The Slow Charging Conundrum

A 40mm Watch 9 owner documented a full charge taking over two hours, while a Watch Ultra 2 user reported a staggering four-hour wait under normal conditions. These experiences are drastically different from Samsung's official figures. The primary culprit appears to be aggressive thermal throttling, where the watches repeatedly throttle charging power as heat builds up, dropping from 5.5W to 3.5W or lower.

Compatibility and Cooling Hacks

The problems don't end with heat management. Users are also reporting issues with charger compatibility. Several reports indicate that backwards compatibility with Galaxy Watch 8 chargers and third-party charging docks is likely broken, with devices displaying 'slow charging' alerts or outright rejecting the power source. Interestingly, some owners found that using an older Watch 6 puck delivered faster results than the included fast-charging cable, suggesting a possible firmware handshake issue.

Samsung's Response and User Solutions

While the problem doesn't affect every user, the consistent complaints are concerning. Samsung has been contacted for an official comment, but the company has yet to address the issue directly. In the meantime, users are resorting to creative solutions, such as using fans and ice baths to cool their devices, highlighting the need for a software fix.

Broader Implications and Future Developments

This issue raises questions about Samsung's software optimization and the potential impact on user experience. It also highlights the importance of thorough testing and compatibility checks. As the number of affected users grows, it will be crucial for Samsung to address this issue promptly to maintain customer satisfaction.

In conclusion, the slow charging speeds on the Galaxy Watch 9 and Watch Ultra 2 are a significant concern for early adopters. While some users are finding creative solutions, a software fix is desperately needed. Samsung must act quickly to resolve this issue and ensure a positive user experience.
