TL;DR The Galaxy S26 Ultra supports faster 25W wireless charging, but users report difficulty reaching these speeds even with official accessories.
Case manufacturer dbrand claims a “proprietary handshake” related to Qi2.2 may be preventing third-party and even Samsung’s own magnet cases from hitting the 25W ceiling.
While 15W wireless charging remains reliable, the requirement for a specific wireless charger, 45W brick, and compatible Qi2 case is creating consumer confusion.
One of the bigger highlights on the Galaxy S26 Ultra is its faster 25W wireless charging speeds. To get these speeds on your Galaxy S26 Ultra, you’ll need the new $50 Samsung Magnet Wireless charger, a compatible 45W power brick, and a Qi2-compatible case for perfect alignment. However, there’s some peculiar behavior at play here: it seems the Galaxy S26 Ultra can’t reach its peak 25W wireless charging speeds with Samsung’s official first-party cases, and the oddity extends to third-party cases as well.

Reddit user Time-Credit43 mentioned that they weren’t getting 25W wireless charging speeds on the Galaxy S26 Ultra when using with popular case maker dbrand’s Ghost case (h/t Piunikaweb).
In response, dbrand told the user that not only do they need the new Samsung Magnet Wireless charger, a 45W power brick, and a case with magnets, but also that the case should have “proprietary Qi2.2 magnets.”
Expanding on this, dbrand tested a bunch of first-party Samsung magnet cases with Samsung’s Magnet Wireless Charger and 45W Travel Adapter. The tested cases for the Galaxy S26 Ultra include the Silicone Magnet case ($55), Clear Magnet case ($50), Rugged Magnet case ($80), and Slim Magnet case ($70). Ironically, none of these cases can hit 25W in wireless charging speeds, though 15W was reliably achieved across them.
