Qi2 (pronounced "chee-two") is the next-generation wireless charging standard developed by the Wireless Power Consortium (WPC). Unlike traditional Qi charging, Qi2 integrates a magnetic alignment system, inspired by Apple’s MagSafe technology, to improve charging efficiency and positioning.
With Qi2, you get:
Up to 15W charging speed
Less heat, better battery health
Stronger connection, reduced energy loss
2. Does Samsung S25 Ultra Have Qi2?
Yes, theS25 Ultra supports Qi2 wireless charging at 15W. The official say is "Qi2 Ready". However, unlike MagSafe-enabled iPhones, it does not have built-in magnets.
What Does That Mean?
Without magnets, your phone won’t automatically snap into place on a Qi2 charger. If it's misaligned, charging could be slower or less efficient.
✅ Solution: Use a Qi2-compatible magnetic phone case to align your phone with the charger properly.
Qi2 delivers up to 15W, which is better than standard Qi (10W) but still slower than wired charging (45W).

4. Does Qi2 Work with MagSafe Chargers?
Some MagSafe chargers will work with Qi2, but since the S25 Ultra lacks built-in magnets, it may not align properly. A Qi2-compatible case ensures the best experience.
Should You Use Qi2 on the S25 Ultra?
Use Qi2 if you prefer wireless convenience with improved efficiency. Use wired charging if speed is your priority.
With the right accessories, Qi2 can be a great upgrade for your S25 Ultra. Just don’t forget the magnetic case.
