Galaxy S25 Qi2 Wireless Charging: The Catch

The Galaxy S25 series supports Qi2 wireless charging, but with a significant catch: it does not include the magnetic alignment ring that defines the Qi2 standard. This means you get the faster 15W charging speed of Qi2, but you lose the automatic snap-on alignment that makes magnetic accessories work seamlessly.

What Qi2 Actually Promises

Qi2 is the latest wireless charging standard from the Wireless Power Consortium (WPC), introduced in 2023. Its headline feature is the Magnetic Power Profile (MPP), which uses a ring of magnets to align the phone perfectly with the charging coil. This alignment reduces energy loss and allows for consistent 15W charging across devices, regardless of brand. The standard was designed to bring the convenience of Apple’s MagSafe to the wider Android ecosystem.

For a phone to be officially Qi2-certified, it must include both the magnetic ring and the required charging hardware. The Galaxy S25 series, however, is not Qi2-certified. Instead, Samsung implemented the underlying charging technology without the magnets, likely to save cost and keep the device thin. This means the S25 can charge at Qi2 speeds with compatible chargers, but it won’t stick to magnetic accessories like wallets, car mounts, or battery packs.

The Catch: No Magnets Inside

The absence of magnets is the core issue. Without them, the phone won’t snap into place on a Qi2 charger. You’ll need to manually position it, and even then, the alignment may not be perfect, which can lead to slower charging or intermittent connection. More importantly, all the magnetic accessories that make Qi2 appealing—like pop sockets, magnetic car vents, and detachable power banks—simply won’t attach to the S25’s back. You’ll need to buy a separate magnetic case to add that functionality, which adds bulk and cost.

Samsung’s decision is a notable departure from its own Galaxy S24 series, which also lacked magnets but was marketed as supporting “Qi2 Ready” via cases. The S25 follows a similar pattern, but the company has been quieter about it this time, likely because consumers and reviewers have become more aware of the distinction.

How Qi2 Charging Works on the S25

When you place a Galaxy S25 on a Qi2-certified charger, it will charge at up to 15W, the same speed as the official Qi2 spec. The phone’s charging coil is positioned in the center, so you’ll need to align it manually. In practice, most Qi2 chargers have a flat surface with a visible coil indicator, making alignment easier than with older Qi chargers. However, if you use a case, especially a thick one, the alignment becomes more finicky.

To get the magnetic experience, you have two options: buy a magnetic case (like those from Spigen or ESR) or stick a magnetic adapter ring onto your existing case. Both add a layer between the phone and the charger, which can slightly reduce charging efficiency and generate a bit more heat. The phone will still charge at 15W, but the convenience of “it just snaps on” is gone.

What This Means for Accessories

The accessory ecosystem is where the lack of magnets hurts most. Qi2 was supposed to unify Android accessories, but with the S25 not having magnets, you’re back to the old problem: each phone needs its own case to work with magnetic gear. Here’s a quick breakdown of what works and what doesn’t:

• Qi2 chargers (pads and stands): Work fine, but you must align the phone manually. Charging speed is 15W.
• Magnetic car mounts: Won’t hold the phone unless you add a magnetic case or adapter.
• Magnetic battery packs (like Anker’s MagGo series): Won’t attach to the phone directly. You’ll need a case with magnets.
• Magnetic wallets or pop sockets: Won’t stick to the bare phone.

In short, the S25 is Qi2-compatible for charging, but not Qi2-compliant for magnetic attachment. This is a subtle but crucial difference that most consumers won’t realize until they try to use a magnetic accessory.

Comparison: S25 vs. Other Qi2 Phones

To understand the catch, compare the S25 to phones that fully embrace Qi2. The Google Pixel 9 series, for example, includes the magnetic ring and is Qi2-certified. When you place a Pixel 9 on a Qi2 charger, it snaps into place automatically, and all magnetic accessories work without a case. The iPhone 15 and 16 are also fully Qi2-compliant. Samsung’s decision to skip the magnets puts the S25 at a disadvantage in this regard.

However, Samsung’s approach isn’t without merit. By omitting the magnets, the S25 is slightly thinner and lighter than it would be otherwise. The magnets also add cost, and Samsung may have chosen to pass those savings to consumers. But for a flagship phone that costs over $800, the absence of a core feature of the latest standard feels like a cost-cutting measure that undermines the user experience.

Common Problems and Misconceptions

One common misconception is that the S25 will charge slower without magnets. That’s not true—the charging speed is determined by the coil and the charger, not the magnets. The magnets only affect alignment and accessory compatibility. Another misconception is that you can just buy a Qi2 charger and it will work perfectly. It will work, but you’ll need to place the phone precisely, and if you move it slightly, charging may stop and restart.

Another issue is heat. Without perfect alignment, the charging coil may not be fully covered, leading to more energy lost as heat. Over time, this can degrade battery health faster than with perfect alignment. Samsung’s own wireless charging pads have a small LED that indicates proper alignment, but third-party chargers may not.

If you’re coming from a MagSafe iPhone, you’ll notice the difference immediately. The S25 won’t “click” onto chargers, and your existing magnetic accessories won’t work without a case. If you’re new to wireless charging, you might not care about the magnets, but you’ll still need to be careful with placement.

Should You Buy a Magnetic Case?

If you want the full Qi2 experience, a magnetic case is the only practical solution. Most major case brands now offer MagSafe-compatible cases for the S25, with the magnets built into the case. These cases are typically 1-2 mm thicker than standard cases, but they restore the snap-on functionality. You’ll also need to ensure the case is compatible with the S25’s camera module and button placement.

When choosing a magnetic case, consider the strength of the magnets. Some cheaper cases have weak magnets that can’t hold the phone securely on a car mount. Look for cases with at least 1,200 g of magnetic holding force, which is the standard for MagSafe accessories. Also, check that the case doesn’t interfere with the S25’s own wireless charging coil—most reputable brands test for this.

If you don’t want a case, you can buy a magnetic adapter ring (a thin metal ring with adhesive) and stick it to the back of your existing case. This is a cheaper option, but the ring may not be perfectly aligned with the charging coil, leading to slower charging or overheating. It’s a workaround, not a solution.

Frequently Asked Questions

Will the Galaxy S25 charge at 15W on a Qi2 charger?

Yes, the S25 supports 15W wireless charging, which matches the Qi2 spec. It will charge at that speed on any Qi2-certified charger, but you must align the phone manually since there are no magnets to guide you.

Does the S25 have a magnetic ring inside?

No, the S25 does not include the magnetic ring that is part of the Qi2 standard. This is the “catch”—it charges at Qi2 speeds but lacks the magnetic alignment feature.

Can I use MagSafe accessories with the S25?

Not directly. MagSafe accessories rely on magnets, and the S25 doesn’t have them. You’ll need a magnetic case or a magnetic adapter ring to use items like MagSafe wallets, car mounts, or battery packs.

Is the S25 Qi2-certified?

No, Samsung has not sought Qi2 certification for the S25 series. It uses the same charging technology but omits the magnetic profile, so it cannot be certified as Qi2-compliant.

Will a magnetic case reduce charging speed?

Generally, no. A well-designed magnetic case will not significantly reduce charging speed, but it may add a small amount of heat. Ensure the case is Qi2-compatible and doesn’t have a thick metal plate that could interfere with the coil.

Should I wait for the S25 Ultra or buy a different phone for Qi2?

If magnetic accessories are a priority, consider a phone like the Pixel 9 or iPhone, which have built-in magnets. If you prefer Samsung’s ecosystem and don’t mind buying a case, the S25 is still a great phone, but you’ll be making a compromise.
