Qi2 25W (Qi2.2) Wireless Charging: What You Should Know

In April 2025, the Wireless Power Consortium (WPC) introduced a major upgrade to the Qi standard—Qi2 25W, also known as Qi2.2. It’s so popular because it’s faster, more stable, efficient, and safer.

In this guide, we’ll break down what Qi2 25W (Qi2.2) actually changes, how it compares to earlier Qi2 generations, and which devices can truly take advantage of the faster charging.

Key Takeaways

• Qi2 25W (Qi2.2) increases the maximum power output of the universal wireless charging standard from 15W to 25W.
• To achieve full 25W wireless charging speeds, users must utilize a certified Qi2 25W (Qi2.2) charger paired with a USB-C Power Delivery (PD) wall adapter rated at 30W or higher.
• The standard utilizes the Magnetic Power Profile (MPP) 2.0 to ensure precise alignment, which reduces energy loss and allows compatible devices to reach a 50% charge in approximately 30 minutes under optimal conditions.
• Compatibility for the 25W "fast lane" is limited to the iPhone 16 series (excluding iPhone 16e) and select 2026 flagship Android devices from Samsung and Google.
• Qi2 25W (Qi2.2) hardware is fully backward compatible, allowing older Qi and Qi2 devices to charge safely at their original maximum supported speeds.

What is Qi2 25W (Qi2.2)?

Qi2 25W (Qi2.2) is the latest upgrade to the Qi wireless charging standard from the Wireless Power Consortium (WPC). Its biggest improvement is that it builds on Qi2 by increasing the maximum wireless charging power to 25W. 

In terms of how it works, Qi2 25W (Qi2.2) is still based on inductive wireless charging, but adds magnetic alignment to keep the phone perfectly positioned on the charger. This improves efficiency and stability, allowing power to scale up to 25W when supported by both the phone and the charger.

Qi2 25W (Qi2.2) vs. Qi2: What’s the Difference?

WPC has defined several major Qi wireless charging standards, including Qi, Qi (EPP), Qi2, and Qi2 25W (Qi2.2). Among them, Qi2 and Qi2 25W (Qi2.2) are the most popular in recent years and also the easiest to confuse. The table below highlights the key technical differences between the two:

Increased Power Output (15W to 25W)

Real-world testing shows a Qi2 25W (Qi2.2) charger can push a smartphone from 0% to 50% in roughly 30 minutes, compared to what could be 45-50 minutes with the older 15W standard. That means Qi2 25W (Qi2.2) delivers nearly 70% more charging power for quick top-ups.

Refined Magnetic Power Profile (MPP)

Stronger magnetic alignment keeps the connection stable and delivers the full 25W efficiently, whether your phone is mounted for navigation or shifting on a desk. The improved lock prevents power drops and reduces heat loss.

Better Efficiency and Thermal Management

Qi2 25W (Qi2.2) wireless chargers benefit from upgraded communication protocols that dynamically adjust power levels instead of pushing maximum output at all times. As a result, many next-generation wireless chargers run cooler than earlier 15W models, helping protect long-term battery health while still delivering fast and reliable charging speeds.

Which Devices Support Qi2 25W (Qi2.2)?

Not all devices support Qi2 25W (Qi2.2), so before upgrading your charger or reworking your desk setup, it’s worth confirming that your phone can actually take advantage of the 25W fast lane. 

The quickest way to check is in your phone’s Battery or Charging settings, or by looking at the spec sheet on the manufacturer’s website. If you see references to Qi2 25W (Qi2.2) wireless, or the Qi2 logo, you’re likely good to go.

Below are two examples of devices that support Qi2 25W (Qi2.2).

1. Apple Devices with Qi2 25W (Qi2.2) Support

Apple helped set the foundation for this standard with MagSafe, and the iPhone 16 lineup (when updated to iOS 26 and excluding the iPhone 16e) fully supports Qi2 25W (Qi2.2) when paired with a certified charger and a strong enough wall adapter. While Apple still uses the MagSafe name, under the hood, these phones work seamlessly with the Qi2 25W (Qi2.2) protocol.

2. Android Phones with Qi2 25W (Qi2.2) Support

Qi2 25W (Qi2.2) support on Android remains limited to select premium models. As of early 2026, only flagship devices from Samsung’s S-series and Google’s Pixel lineup include the Magnetic Power Profile (MPP). While these high-end phones now match iPhone charging speeds, adoption across the broader Android ecosystem is still in its early stages.

Notes: Your phone is only part of the equation. To actually hit 25W, you’ll need a USB-C Power Delivery (PD) adapter rated at 30W or higher. Older 5W or 12W wall bricks simply don’t have enough overhead to support fast wireless charging, so the system will automatically fall back to slower speeds if the adapter can’t keep up.

How Do You Unlock Qi2 25W (Qi2.2) On Your Phone?

Hitting the full 25W wireless charging speed isn’t just about owning a new phone, it’s about making sure your entire charging chain is dialed in. If any part of that chain is underpowered or misaligned, your phone will automatically fall back to 15W or even 7.5W. Here’s how to make sure you’re actually getting peak Qi2 25W (Qi2.2) performance.

Step 1: Verify Device Compatibility

Start with the basics: the phone itself. In 2026, the iPhones are the main drivers of Qi2 25W (Qi2.2), along with several flagship Android phones that support the Magnetic Power Profile (MPP). If you’re still on an iPhone 15 or an early Qi2 Android model, you’ll get the magnetic snap and stability, but charging speed will be capped at 15W.

Step 2: Use a 30W+ USB-C PD Power Adapter

This is where a lot of setups fall short. A 20W wall charger might seem fine, but once wireless conversion losses are factored in, it can’t sustain a full 25W output. To unlock Qi2 25W (Qi2.2) speeds, you’ll need a 30W or 45W USB-C Power Delivery (PD) adapter. A higher capacity PD adapter provides the stable power flow needed for fast wireless charging while keeping temperatures under control.

Step 3: Mind Your Magnetic Case (The 2 mm Rule)

Cases can quietly kill fast charging. Thick or non-magnetic cases increase the gap between your phone and the charger, which leads to extra heat and automatic throttling. To maintain 25W charging, your case should be under 2 mm thick and include a built-in magnetic ring. For the best snap-on alignment and consistent top speeds, stick with cases that are officially Qi2 or MagSafe compatible.
