Magnetic wireless chargers are loved by a large user group for their charging convenience! However, their charging speed has never met people’s expectations. In December 2024, the WPC Wireless Power Consortium launched the new Qi2.2 standard, which increased the wireless charging speed from 15W in Qi2.1 to 25W, bringing a new breakthrough to the field of wireless charging. So, what are the significant improvements of Qi2.2 compared to Qi2.1? Brands that want to customize magnetic wireless power banks may wish to learn more about it!
1 What is the Qi2.2 wireless charging protocol?
The Qi2.2 wireless charging protocol is an upgrade based on the Qi2.1 wireless charging protocol. It increases the charging power from the original 15W to 25W. It was launched by the WPC in December 2024 and officially released in July 2025!
Versions of Qi Wireless Charging Protocols Through the Ages
| Version | Release time | Maximum power | Core features | Magnetic alignment | Application scenarios | Compatibility with older versions |
| Qi1 | 2010 | 7.5W(BPP)
15W(EPP) |
First-generation inductive wireless charging | No | Mobile phones, earphones | No need for compatibility |
| Qi2.0 | 2023 | 15W | Introduce magnetic attraction features | Yes | Mobile phones, magnetic accessories | Yes |
| Qi2.1 | 2024 | 15W | Add magnetic shell support and vehicle-mounted alignment | Yes | Mobile phone + case, vehicle-mounted scenario | Yes |
| Qi2.2 | 2024 | 25W | High-power magnetic attraction | Yes | High-power mobile phone devices | Yes |
2 What are the significant improvements of Qi2.2 compared to Qi2.1?
The Qi2.2 wireless charging protocol has been optimized mainly in terms of charging power, magnetic attraction stability, and temperature control management, with the specific improvements as follows:
1） Improvement in charging power（15W → 25W）
| Version | Maximum power | Applicable scenarios |
| Qi2.1 | 15W | mobile phone |
| Qi2.2 | 25W | Mobile phones, tablets, foldable screen devices |
Qi2.2 supports 25W wireless fast charging, which is a 66% increase compared to Qi2.1’s 15W, approaching the speed of some wired fast charging (such as iPhone’s 20W PD fast charging).
2） Enhanced magnetic alignment and adsorption force
| Version | Magnetic attraction requirements | Alignment accuracy |
| Qi2.1 | ≥9N | A deviation of ±2mm may affect charging efficiency. |
| Qi2.2 | ≥12N（Some manufacturers reach 15N.） | ±1mm high-precision alignment |
Stronger adsorption force: Prevents disconnection of charging when the phone shakes (such as in vehicle-mounted scenarios).
Automatic fine-tuning alignment: Some high-end chargers support dynamic adjustment of coil positions to improve energy transmission efficiency.
3） Optimization of temperature control management (reducing overheating-induced frequency reduction)
| Version | Temperature control mechanism | Actual performance |
| Qi2.1 | Basic temperature control, prone to power reduction due to high temperature | It may drop to below 10W during long-term charging. |
| Qi2.2 | Dynamic temperature control + heat dissipation optimization | The 25W full power lasts longer, reducing heat-induced frequency reduction. |
Improvement points:
Adopt a more accurate temperature sensor to avoid false triggering of power reduction.
Optimize the coil heat dissipation design to reduce the surface temperature of the wireless charger.
4） Compatibility expansion (supporting more types of devices)
Qi2.1: Mainly targets small devices such as mobile phones (e.g., iPhone 12-16 /HMD/Samsung), headphones, phone cases, and speakers. Qi2.2: Newly added support for tablets and foldable screen mobile phones (e.g., iPad Pro may be compatible in the future).
5） Safety upgrade (optimization of foreign object detection)
The FOD (Foreign Object Detection) of Qi2.2 has a faster response, avoiding the risk of overheating caused by accidental contact with metal objects (such as keys). A new camera/sensor interference test has been added to prevent magnetic charging from affecting mobile phone functions (such as compatibility with Samsung S Pen).
Summary: Core advantages of Qi2.2
| Comparison Dimension | Qi2.1 | Qi2.2 |
| Power | 15W | 25W (66% faster) |
| Magnetic Force | 9N | 12N+ (more stable adsorption) |
| Temperature Control | Basic management | Dynamic adjustment + efficient heat dissipation |
| Compatibility | Phones/headphones/phone cases | Phones/tablets/foldable screens |
| Safety | Standard FOD | Enhanced foreign object detection |
3 Which devices will be compatible with the Qi2.2 wireless charging protocol?
According to relevant sources, the entire iPhone 17 series, Samsung Galaxy S26 and other flagship models will support the Qi2.2 wireless charging protocol; the Google Pixel 10 series (expected to be released in October 2025) will directly integrate magnetic components, supporting a maximum hardware power of 60W (the actual charging power will be set by Google), and will launch a supporting magnetic ecosystem “Pixelsnap” (including chargers, brackets and other accessories). It is expected that more electronic devices will support the Qi2.2 wireless charging protocol in the future! This is undoubtedly a huge business opportunity for electronic device accessory suppliers!
