Samsung’s Galaxy S25 Ultra is making headlines for many reasons, and one of the most talked-about features is its support for Qi2 wireless charging. But what exactly is Qi2, and how does it improve your charging experience, if at all? Let’s find out.
What is Qi2 Charging on the Galaxy S25 Ultra?
Qi2 is the next generation of wireless charging technology, developed by the Wireless Power Consortium (WPC). It’s an evolution of the widely-used Qi standard and introduces key improvements, including better efficiency, compatibility, and reliability. Most notably, Qi2 includes Magnetic Power Profile, which ensures perfect alignment between your phone and the charger.
This eliminates energy loss during charging and delivers a more consistent and faster charge. For Galaxy S25 Ultra users, this means fewer interruptions and better performance compared to older wireless charging methods. Qi2 minimizes energy wastage and reduces heat generation, effectively helping extend your phone’s battery lifespan over time.
While the official Qi2 specification limits wireless charging to 15W, the Galaxy S25 Ultra is rumored to support 25W wireless charging. The company has probably implemented a proprietary solution to push the speed to 25W. But this also means you will require a compatible charger. Most Qi2 chargers may not charge the devices at full speed.
MagSafe compatibility via a protective case
With Qi2’s magnetic alignment, Galaxy S25 Ultra users can now benefit from features similar to Apple’s MagSafe ecosystem. Samsung is expected to launch Qi2-compatible cases for the Galaxy S25 series, enabling users to attach magnetic accessories like wallets, stands, and battery packs seamlessly. The phones may not offer built-in magnets though, so you need a supported case to benefit from this upgrade.
Long story short, Qi2 enables faster and more efficient wireless charging on your Galaxy S25 Ultra. It also extends the battery life and allows you to attach magnetic accessories. To take full advantage of this feature, you’ll need a Qi2-certified wireless charger capable of 25W charging and a Qi2-compatible case.
If you’re planning to upgrade to the Galaxy S25 Ultra, investing in these two additional accessories could be a great way to make the most of this new feature — the Galaxy S25 and S25+ should also support Qi2 wireless charging. Samsung has already opened pre-reservations for the upcoming flagships.
