Other improvements brought by QI2 include wider device compatibility (from tablets to wearables), adaptive charging so that the charger can talk to the device to provide the power needed without having to have a fixed power output, and enhanced security with better thermal management and foreign object detection.
What is QI2 25W?
The first major update to the QI2 standard is QI2.2.1, which WPC calls QI2 25W. While it won’t do anything to shed light on the wireless charging scenario, it can achieve many improvements:
- Faster charging speeds up to 50 wattsalthough it seems that 25 watts will be the norm now.
- Improved magnetic alignmentso the phone can be charged with maximum efficiency and speed, and different devices will be compatible with all QI2 25W accessories.
- Backward compatiblewhich means that the QI2 25W device will still be used with the QI2 and QI chargers, albeit slower.
WPC says 14 products have been certified so far, including 3-in-1 chargers, power banks and car racks from Anker, Aukey, Aukey, Baseus, Belkin, Ugreen and Scosche, and hundreds of them in the certification queue. Most interestingly, WPC said, “The main Android smartphones will join the QI2 ecosystem for the first time, except for Apple iPhones.” But we don’t know what iPhone model or Android phone it refers to.
The complete list of QI2 phones
Sadly, there are not many QI2 certified phones. Here is the full list:
Complete list of QI2 ready phones
A QI2-ready phone is able to charge at QI2 speed, but lacks a magnetic array, so it must be paired with a QI2-ready situation where the magnets in the magnet act as the QI2 phone. Here is the list:
Expected delay waves for Qi2 devices
Before the device can carry the QI2 or QI2 25W logo, the Wireless Power Alliance must authenticate it in its independent lab. MPP QI2 specifications include charging rate, magnet strength and device compatibility. The QI2 logo promises that the device complies with strict WPC standards. However, like the original QI standard, there are also available devices that have not yet passed the official QI2 certification process.
Apple’s iPhone 12 to 16 series supports QI2, as well as accessories manufacturers such as Anker, Belkin, Nomad, Mophie, Baseus, and many others have released QI2 wireless chargers and power libraries. You can expect a wave of QI2 25W accessories and phones to be launched next, and we hope some Android manufacturers will join in full later this year or early 2026. Phones usually have two years of delivery, so delays in adopting QI2 may be delayed. WPC hopes that QI2 will unify wireless charging and ultimately provide the universal global standard we have been waiting for, but we are no longer very optimistic.
