What you need to know
- The Galaxy S26 Ultra supports wireless charging up to 25W, but most users struggle to reliably achieve these speeds.
- The phone does not have Qi2 magnets, as Samsung requires special chargers and magnetic cases.
- Tests show that even official Samsung cases limit the wireless charging speed to around 15W instead of 25W.
Next to it wireless charging upgrade to 60W On the Galaxy S26 Ultra, Samsung has also increased the wireless charging speed to 25W. However, it seems that most users will not be able to reliably achieve these speeds.
Samsung again skipped adding internal Qi2 magnets On the Galaxy S26 Ultra. Instead, it continues to rely on the same approach as the Galaxy S25 Ultra, asking users to use a compatible magnetic case for “Super Fast Wireless Charging” up to 25W. Even so, these speeds do not appear to be reliably achievable in many cases.
For this faster wireless charging, Samsung recommends using a first-party magnetic wireless charger with a 45W travel adapter and official magnetic cases for a proper fit. If you use other accessories, it seems unlikely that you will consistently reach the advertised 25W speed.

A user Reddit reached out case maker noted to dbrand that their Grip case only delivers 15W of power instead of the expected 25W. The company responded that it cannot achieve 25W wireless charging in all cases, citing that Samsung uses “proprietary Qi2.2 magnets” in first-party cases that third-party brands cannot fully replicate.
Dbrand he also said Tested a few cases with Samsung’s own Silicon Magnet, Clean Magnet, Strong Magnet, and Slim Magnet cases, along with the official 45W charger.
Even with these connections, they couldn’t beat the 15W charging speed. This suggests the issue isn’t limited to third-party accessories, as even Samsung’s own boxes struggle to hit the claimed speeds.
Android Central’s Take
This situation seems unnecessarily complicated. Samsung could have avoided a lot of this confusion by incorporating built-in Qi2 magnets into the phone itself. Instead, the current approach creates inconsistency and frustration around something as basic as charging.
What makes things more confusing is that Samsung labels both the 15W and 25W as “Super Fast Wireless Charging”. This makes it difficult for users to know how fast their phone is actually charging. We will contact Samsung for clarification and update once we have more details.
