Samsung Prepares Long‑Awaited Wireless Charging Boost
Samsung may finally be ready to overhaul its wireless charging technology with the upcoming Galaxy S26 series, according to new findings from early One UI 8.5 builds. Strings referencing “Super fast wireless charging” have been discovered, hinting at a significant leap forward for the company’s next flagship lineup.
The discovery arrives amid years of criticism from users who have long pushed Samsung to modernize its wireless charging speeds, which have remained unchanged since 2020.
Rumored Charging Speeds for the S26 Lineup
Based on the leaked information, Samsung appears to be preparing its biggest wireless charging upgrade in half a decade:
- Galaxy S26 Ultra: Up to 25W wireless charging
- Galaxy S26 / S26+: Up to 20W wireless charging
This would mark a notable improvement over the 15W limit on the Galaxy S25 series and earlier models.
If accurate, the upgrade could deliver up to 40% faster charging, significantly reducing the time users spend tethered to a charging pad.
New Branding Signals a UI Refresh
The One UI 8.5 code includes a new system label for “Super fast wireless charging,” suggesting Samsung may introduce clearer distinctions between charging tiers:
- Super fast wireless charging (new, higher speeds)
- Fast wireless charging (current 15W standard)
- Wireless charging (low‑power chargers)
This branding shift indicates Samsung may actively promote the enhanced speeds as a key feature of the S26 lineup.
Samsung’s Position in the Charging Race
While Samsung has maintained conservative charging speeds for years, competitors—particularly Chinese manufacturers—have surged ahead with 50W to 80W wireless charging solutions.
If Samsung adopts the rumored upgrades, the Galaxy S26 series could help narrow the gap and strengthen the company’s position in the premium smartphone market.
What Happens Next?
As with all leaks derived from APK teardowns, these findings reflect potential features rather than confirmed specifications. Samsung may adjust or remove the functionality before launch.
However, if the upgrades move forward, the Galaxy S26 series could mark a turning point in Samsung’s charging strategy, offering users faster, more competitive wireless performance.
More details are expected to surface as development continues and the S26 lineup approaches its 2026 reveal cycle.
