Samsung's next software update, One UI 8.5, hints at a meaningful boost to wireless charging for the Galaxy S26 family. Leaked firmware references point to a new "Super Fast Wireless Charging" mode that could narrow the gap between wired and wireless speeds.
What the leak actually shows
Code found in One UI 8.5 firmware references a feature labeled "Super Fast Wireless Charging." That language lines up with earlier rumors that the Galaxy S26 Ultra may support up to 25W wireless charging, while the S26 and S26+ could land with 20W wireless charging. These changes would mark one of the biggest wireless-speed upgrades Samsung has made in years.
How fast could it be in real life?
If the S26 Ultra ships with a 5,200mAh battery and 25W wireless charging, expect roughly a full charge in about an hour under optimal conditions — bringing wireless charging close to the 45W wired speeds seen on Samsung's recent flagship wired chargers. That’s a big step for convenience: imagine less tethering to cables and faster top-ups on compatible charging pads.
Built-in magnets and Qi2 compatibility — convenience matters
Beyond pure wattage, the leaks suggest Samsung will add built-in magnets across the S26 line to help automatic alignment with compatible wireless chargers. That also paves the way for native Qi2 support and accessories like magnetic wallets, charging stands, car mounts, and power bands — improving day-to-day usability, not just headline charging numbers.
Where Samsung sits compared to rivals
Some Chinese manufacturers already advertise 50W (and higher) wireless charging, but they typically rely on proprietary technologies and chargers. Samsung, like Apple and Google, prefers to stick with the Qi standard. If Samsung raises wireless speeds to ~25W while keeping Qi compatibility, it could offer a pragmatic blend of safety, accessory ecosystem support, and faster charging without fragmenting standards.
Will wireless charging finally feel as snappy as wired? Not quite at the highest proprietary bracket, but One UI 8.5's hints suggest Samsung is closing the gap — and making wireless top-ups more convenient through magnets and Qi2 support. Keep an eye on firmware teardowns and official Samsung announcements as we get closer to the S26 launch.
