Samsung was one of the first Android smartphone brands to add wireless charging for high-end devices. After increasing Wireless charging speed up to 15Wit didn’t improve it much.
The company is now trying to make wireless charging faster for everyone by joining the Wireless Power Consortium (WPC) and participating in the development of Qi 2.2.
Samsung’s PMIC chip, S2MIW06, is future-proof and enables fast wireless charging up to 50W.
System LSI, a division of Samsung that develops semiconductor chips and sensors, announced new integrated power management chip (PMIC). It’s called S2MIW06 and it controls wireless charging. This chip allows for much faster charging – up to 50W in receiver mode.
It supports all Qi extensions including Basic Power Profile (BPP), Extended Power Profile (EPP) and Magnetic Power Profile (MPP).
BPP supports wireless charging up to 5W, and EPP increases wireless charging power to 15W. EPP is used in most of the high-end Galaxy phones released in the last few years.
MPP is required for the Qi2 badge (which is different from Qi2 Ready) and supports up to 25W wireless charging. The MPP features a magnetic alignment mechanism that allows the phone to perfectly align with the wireless charger using strong magnets. This technology was developed by Applewhat then donated it to WPC.
Samsung says the S2MIW06 chip has been extensively tested to ensure compatibility with hundreds of Qi-certified wireless chargers and chargers. Moreover, it has also been tested with hundreds of non-certified chargers. It provides stable wireless charging on a wide range of chargers.
In transmit mode, the company’s new PMIC supports wireless power sharing. This is the same feature that allows Samsung Galaxy phones to wirelessly charge other devices such as smartwatches, wireless headphone cases, and even other phones.
Samsung is developing Qi v2.2 together with other brands
The South Korean firm reports the latest version of Qi 2.2, which WPC recently mentioned. Like Google, System LSI is actively working on implementing Qi v2.2. Thus, future Samsung devices may have Qi v2.2 for faster wireless charging.
Recently it became known that Samsung will sell cases from its own manufacturers with the Qi2 Ready badge for the Galaxy S25 series. This likely means that phones may not have the magnets needed for the MPP profile, and cases may help the phone with magnetic alignment.
Let’s hope future Samsung phones will have a full implementation of Qi v2.2 for fast wireless charging at 25W or even 50W. In any case, it’s good to know that Samsung is working with WPC on the Qi v2.2 system and is thinking about introducing faster wireless charging throughout the ecosystem.
