Samsung's Galaxy S26 Ultra promises 25W wireless charging, but most users struggle to achieve those speeds consistently. The company requires specific chargers and magnetic cases, as the phone lacks built-in Qi2 magnets. Tests show even official Samsung cases often cap charging speeds around 15W instead of 25W.

This limitation stems from Samsung's decision to skip integrated Qi2 magnets, instead relying on proprietary magnetic alignment similar to the Galaxy S25 Ultra. For optimal performance, Samsung recommends its first-party magnetic wireless charger with a 45W travel adapter and official magnetic cases. However, even this combination frequently fails to reach advertised speeds.

Reddit user reports and testing by case maker dbrand confirm the issue isn't limited to third-party accessories. Their tests with Samsung's own Silicone Magnet, Clear Magnet, Rugged Magnet, and Slim Magnet cases alongside the official 45W charger couldn't exceed 15W charging speeds. The situation creates unnecessary confusion, especially since Samsung labels both 15W and 25W as 'Super Fast Wireless Charging,' making it difficult for users to know their actual charging speeds.
