Finally Changed: Galaxy S26 Ultra Receives Major Wireless Charging Upgrade

KOMPAS.com - Samsung has finally delivered a long-awaited upgrade for users of the Galaxy S26 Ultra. The flagship successor to the S25 Ultra now supports wireless charging at 25 watts with Qi2.2 technology. With that figure, the Galaxy S26 Ultra’s wireless charging speed is finally on a par with MagSafe on the iPhone 17 Pro Max. Previously, according to KompasTekno’s investigations, for six years since the Galaxy S20 Ultra launched in 2020, the wireless charging speed in the Ultra line had never changed. From the Galaxy S21 Ultra to the Galaxy S25 Ultra, Samsung consistently stuck at 15 watts. Yet in the same period, the camera jumped to 200 MP, the chipset changed generation after generation, and the design became thinner. However, wireless charging remained stagnant. Qi2.2 is the latest wireless charging standard developed by the Wireless Power Consortium as the successor to Qi2. This technology still uses a magnetic system to ensure precise charging positioning, but delivers higher power up to 25 watts. Thus, wireless charging becomes faster, more efficient, and stable, without compromising cross-brand compatibility. However, a little different from the iPhone, which already has MagSafe magnetic system built into its body, the Samsung S26 Ultra does not yet have it. So, users still need a magnetic case compatible with Qi2. This is because the 25-watt power profile in the Qi standard typically requires active magnetic alignment. Clearly, with the support of 25-watt Qi2.2 wireless charging, Samsung S26 Ultra users will be quicker and more efficient when charging wirelessly. This is especially useful for users who rely on wireless power banks when travelling or wireless pads on the desk or beside the bed. The power upgrade to 25 watts is not just a number increase. According to ETNews, Samsung has partnered with component supplier Witz for the RX wireless charging module in the Galaxy S26 Ultra. Witz redesigned the RX module structure to improve thermal management and power stability. The two main issues with high-power wireless charging, overheating, and unstable power supply, are claimed to have been addressed. Interestingly, the changes also help keep the design slim. The Galaxy S26 Ultra is said to have a thickness of only 7.9 mm, about 0.3 mm thinner than its predecessor.
