Summary

Samsung's S26 Ultra promises 25W wireless charging but often hits 15W.
Accessory cases may prevent the phone from reaching top charging speeds.
A 'proprietary handshake' or new standard issues might be the cause.

Samsung's latest Galaxy S26 Ultra offers an enhanced 25W wireless charging capability, a step up from the 15W supported by its predecessor. However, owners are encountering difficulties achieving these advertised speeds.

Reports indicate that third-party cases and even some official Samsung accessories are limiting charging to 15W. Accessory makers like Dbrand point to a potential "proprietary handshake" or issues with the newer Qi2.2 standard as the culprits, rather than the older Qi2.0.

These limitations are causing confusion for consumers trying to ensure they get the fastest possible wireless charging. While some users report success with official Samsung accessories, the inconsistency suggests a complex accessory ecosystem. It is recommended that users opt for official Samsung charging tools and test their speeds to confirm optimal performance.
