TL;DR
- Qi2 boosts wireless charging with 15W speed, magnetic alignment, and improved efficiency over the original Qi standard.
- “Qi2 Ready” means a device can use Qi2 charging but lacks built-in magnets, requiring a special case for proper alignment. This means any phone with wireless charging and a magnetic case is Qi2 Ready.
- The Samsung Galaxy S25 Series and the OnePlus 13 support Qi2 Ready via magnetic cases, but they aren’t true Qi2 devices like iPhones.
- Spigen, ESR, and others offer Qi2 cases, making it work for any phone. Samsung also offers its official Qi2 Ready cases for the S25 series.
Wireless charging has revolutionized the way we power our smart devices. It eliminates the inconvenience of tangled cables and the need to consciously plug in your charger. With wireless charging, you can simply place your device on a charging pad to recharge it. The first generation of this technology, known as Qi1, was introduced to smartphones in 2012, starting with the Nokia Lumia 920.
The subsequent version, Qi2, enhances the wireless charging experience with several advancements. Initially, Qi charging was primarily available for iPhones and other Apple products, but it is now gradually being adopted by Android smartphones as well. This article will explore Qi2 charging, explain what it means for a device to be Qi2-ready, and highlight the best Qi2 cases for the newly launched Galaxy S25 Series.

Qi 2 Charging: What is it?
Qi 2, pronounced Chee-2, is a wireless charging standard created by the Wireless Power Consortium, marking a notable progression in wireless charging technology. Announced in 2023, it integrates features influenced by Apple’s MagSafe technology.
The Qi system operates on a principle similar to that of radio and television, where substantial power is transmitted through a wire, allowing it to transfer energy to another wire. Within the charging pad, a broadcasting coil generates an electromagnetic field, which is captured by a receiving coil in the device, directing the energy to the battery. The effectiveness of this process increases with the size of the coil.
Qi2 Vs Qi: How is Qi2 better?
1. Enhanced Charging Speeds – Qi 2 provides charging capabilities of up to 15W, compared to the 7.5W maximum offered by the original Qi standard.
2. Improved Safety and Efficiency – Qi 2 incorporates a Magnetic Power Field Profile, utilizing a ring of magnets to ensure precise alignment of charging coils. This design guarantees optimal positioning for maximum power transfer while minimizing the risk of overheating. Users benefit from the convenience of Qi 2 chargers, as the magnetic alignment simplifies the placement of devices.
3. Greater Sustainability and Future Readiness – The elimination of cables reduces mechanical stress on charging ports, contributing to a decrease in electronic waste. Additionally, Qi 2 is designed to accommodate the increasing power requirements of future devices.

Smartphones supporting Qi Charging in India
Most of the iPhones and Apple devices support wireless Qi charging in India. However, in the past year, various Android devices have been made Qi-ready.
- Google has confirmed that its future Pixel devices will be Qi2-ready.
- OnePlus 13 is Qi2 ready with the help of a Qi2 charging case.
- The recently launched Samsung Galaxy S25 Series is Qi2 ready with the help of Qi 2 charging case.
However, does being Qi2 ready mean Android phones support Qi2 charging or is there a catch? Let’s find out by talking about how Samsung Galaxy S25 Series is being called Qi2-ready.
What does being Qi2 Ready mean?
Samsung revealed at Unpacked 2025 that the Galaxy S25 Series is now compatible with Qi2 technology. This compatibility allows all three smartphones to utilize Qi 2.1 wireless charging speeds. However, these devices do not feature built-in magnets for aligning with wireless chargers, unlike Apple’s MagSafe system found in iPhones. Instead, the Qi2 compatibility is designed to work with specific magnetic wireless charging cases that can be purchased as accessories.
Users can attach compatible magnetic covers from Samsung or third-party brands like Spigen to take advantage of the magnetic charging capabilities. Therefore, fully integrated Qi2 charging solutions are still a future development for Samsung. Paul Golden, Director of Marketing at the Wireless Power Consortium, stated, “It’s a faster way, an easier way, for a company to offer a Qi2 experience without having to make that big change.”
OnePlus has equipped the OnePlus 13 with Qi2 readiness through a charging case that facilitates magnetic wireless charging. This method is a traditional way of incorporating magnetic charging into phones that support Qi, but it does not convert your devices into Qi2-compatible units. While it may provide a similar experience, it will not enable fast charging speeds and lacks energy efficiency. Additionally, Otterbox and Spigen have introduced magnetic cases designed to support Qi2 charging for the Samsung Galaxy S25 Series.
