Galaxy S26 Ultra magnetic wireless charging speed doesn't reach 25W even with Samsung's case, says dbrand

A few hours ago, we reported on the controversy surrounding dbrand’s cases for the Galaxy S26 Ultra, which reportedly don’t support the phone’s advertised 25W ‘Super Fast Wireless Charging.‘ Now, the accessory maker claims the issue may not be limited to third-party cases.

In a Reddit thread, a Galaxy S26 Ultra user said they contacted dbrand regarding its Ghost case not supporting the device’s 25W wireless charging. The company responded with a detailed explanation—one we covered earlier—but later added further clarification in the same discussion.

According to dbrand, the case maker conducted its own tests on the matter following the complaints. The company says it used Samsung’s official 45W travel adapter, 25W magnetic wireless charger, and Samsung-branded cases, including Silicone Magnet Case, Clear Magnet Case, Rugged Magnet Case, and Slim Magnet Case, to evaluate the phone’s charging performance.

Based on these tests, dbrand claims that the Galaxy S26 Ultra's wireless charging speed does not reach the advertised 25W mark—even with Samsung’s own accessories (read Samsung's case). Instead, the charging speed reportedly remains consistent at around 15W. It’s worth noting that these findings are based on dbrand’s internal testing and user reports, and have not been independently verified.

In the comments, many people have pointed out that the Galaxy S26 Ultra shows Super Fast Wireless Charging when they used magnetic cases from brands like ESR and Spigen and wireless chargers from brands like Belkin. At this point, it's not clear what's going on. We need more reports on the matter to get a clear idea of the issue. Until then, you may want to get a cheap case to protect the device temporarily.
