A Guide to Qi vs Qi2 Wireless Charging

Wireless charging has become easier to use, but the standards behind it have become more layered. Qi remains the established baseline, Qi2 introduced magnetic alignment and more consistent charging, and Qi2 25W now raises the performance ceiling for compatible hardware.

Qi2 is especially relevant to newer iPhone models and a growing range of Android devices, although support and maximum charging speeds still vary by model. Developed by the Wireless Power Consortium, these standards determine how the charger and device align, communicate, and transfer power. This guide explains Qi vs Qi2 charging, where MagSafe fits in, and what the latest 25W standard means for your phone.

What Are Qi and Qi2?

What is Qi? Qi is a wireless charging standard developed by the Wireless Power Consortium (WPC). It transfers energy through electromagnetic induction, using a coil in the charger to generate a magnetic field that transfers power to a compatible receiver coil in the device. Early Qi charging commonly operated at up to 5W, while later versions added optional higher-power profiles, including support for up to 15W.

Qi2 is the newer generation of the standard. Made available in 2024, it added the Magnetic Power Profile (MPP), which uses magnets to align the phone and charger more precisely. Apple contributed technology based on MagSafe to the Wireless Power Consortium for the development of this magnetic power profile.

MagSafe and Qi2 are therefore related, but they are not the same. MagSafe is Apple's technology and accessory ecosystem, while Qi2 is an industry standard available to participating manufacturers.

The key difference is therefore less about wireless charging itself and more about how reliably the charger and device connect, align, and deliver their supported power.

What About Qi2 25W?

Qi2 has already moved beyond its original up to 15W limit. The Wireless Power Consortium launched Qi2 25W in July 2025 as part of Qi v2.2.1, increasing standardized wireless charging power to 25W for compatible devices. The WPC describes this as nearly 70% more charging power than the first version of Qi2.

A Qi2 25W charger can only provide 25W charging to a phone that also supports Qi2 25W. Otherwise, the phone charges at the maximum rate it supports.

For buyers, the key question is whether their phone supports Qi2 25W, not simply whether the charger carries the newer rating.

The Role of Magnetic Alignment

Traditional Qi works best when the transmitting and receiving coils are positioned closely together. If your phone sits off-center on the pad, the connection can become less efficient, potentially reducing charging performance or creating additional heat.

With Qi2 onward, magnetic alignment positions the coils automatically. The charger and device remain in a more consistent position, making wireless charging easier to start and maintain. The WPC identifies magnetic attachment and alignment as defining features introduced with Qi v2.0.

Some Android phones may also use a magnetic case to provide the required attachment system. Either way, the practical benefit is simple: less repositioning on the charging pad.

Is Qi2 Faster Than Qi?

It can be, although the answer depends on the specific charger and phone.

The Qi standard has technically supported up to 15W since Qi 1.2, but manufacturers and devices have not always used the full rate. Different phones can therefore charge at different speeds even when placed on chargers advertising the same maximum output.

Original Qi2 standardized magnetic charging at up to 15W. Qi2 25W raises that maximum to 25W, provided both the charger and receiving device support it.

Actual charging speed can still vary because of battery temperature, current charge level, the connected power adapter, and the device's own charging controls. A 25W charger indicates its maximum capability rather than a constant 25W delivery rate.

Which Devices Work With Qi2?

Qi2 is increasingly the more relevant standard for newer smartphones. It supports compatible iPhones and a growing range of Android devices, while Qi2 25W extends faster magnetic charging to newer hardware from both ecosystems. Samsung, for example, now offers Qi2-compatible charging across recent Galaxy models.

Traditional Qi still matters for older phones, earbuds, vehicles, and accessories, so backward compatibility remains useful. Many Qi2 chargers can also charge Qi devices, although at the lower rate supported by the device.

For buyers in 2026, Qi is best viewed as the compatibility baseline, while Qi2 is the standard to prioritize when choosing new wireless charging hardware. Qi2 25W is also worth considering if your phone supports it and you want access to the newer higher-power charging tier.

Finally, What About Safety?

Both Qi and Qi2 include built-in safety requirements, so Qi2 should not be treated as the first safe wireless charging standard. The main progression is in how those protections have been refined as charging technology has advanced.

• Foreign object detection: Qi already includes checks designed to detect metal objects that could heat up during charging.

• Thermal and power controls: Later Qi revisions expanded safeguards around temperature, authentication, and power management.

• Improved alignment: Qi2’s magnetic positioning helps keep the charging coils properly aligned, reducing avoidable losses caused by poor placement.

• Higher-power safeguards: Newer Qi2 specifications add refinements to power-loss monitoring and foreign object detection as output increases to 25W.

• Certification applies to both: Qi and Qi2 products must meet WPC requirements to be listed as certified. Qi2 certification additionally verifies the newer magnetic alignment and power-profile requirements, so it gives buyers confidence that those Qi2-specific features have been implemented to the standard.

Qi vs Qi2 Charging: Which Should You Choose?

The right choice still starts with Qi vs Qi2. For an older device that supports standard Qi, a good Qi wireless charger may be all you need. Qi2 is more relevant for newer compatible phones because it adds magnetic alignment and standardized charging up to 15W.

There is also a newer option within the Qi2 family: Qi2 25W. If your phone supports it, a matching charger can provide access to higher wireless charging speeds without changing the basic Qi2 experience.

Explore Energea’s wireless chargers and start with the standard your device supports, then consider whether the extra speed of Qi2 25W is useful for your routine.

The best wireless charger is the one that matches what your phone can fully use today, with enough headroom for what comes next.
