## Product: SAMSUNG Galaxy S25 Ultra Cell Phone, 512GB, AI Smartphone, Unlocked Android, AI Camera, Fast Processor, Long Battery Life, 2025, Titanium Black
**Brand:** SAMSUNG

The Galaxy S25 Ultra supports 45W wired fast charging and 15W Qi2.1 wireless charging, though there's an important consideration for wireless users.

**Wired charging speeds:**
- 0 to 70%: ~30 minutes
- Full charge: ~1 hour

This significantly outpaces the iPhone 16 Pro Max, which needs about 2 hours for a full charge. For best results, use the [Samsung 45W Super Fast Charger](https://www.amazon.com/dp/B0DGXLM4FT?tag=shopsavvy-20) or any USB-PD 3.0 charger supporting 45W.

**Wireless charging (Qi2) catch:**

The S25 Ultra is the first Android phone to support Qi2.1, but Samsung didn't include built-in magnets because they affected display and S Pen performance. Without magnets, you lose Qi2's magnetic alignment feature.

**The solution:** Use a [Qi2-compatible magnetic case](https://www.amazon.com/dp/B0DT87SNJR?tag=shopsavvy-20) to get proper alignment and stable 15W wireless charging.

**Charger recommendations:**

For wired charging, ensure your charger actually supports 45W. Many chargers cap at 25W-30W and won't deliver maximum speed.

For wireless, Samsung's official [wireless chargers](https://www.amazon.com/dp/B0DGY3NKMS?tag=shopsavvy-20) work well. Third-party Qi2 pads work best with a magnetic case.

**Perspective on charging speeds:**

Samsung's 45W is good but not industry-leading. Some competitors offer 65W-120W charging. Samsung prioritizes battery longevity over extreme speed, which may extend your battery's lifespan over years of use.
