Galaxy S26 Ultra Slashes Wireless Charging Time with 25W Boost

After six years, Samsung finally upgrades wireless charging on the Galaxy S26 series, with the Ultra model slashing charging time by nearly half.

A Long-Awaited Wireless Charging Boost

Samsung is finally stepping up its wireless charging game with the Galaxy S26 series, breaking a six-year stagnation. Starting with the Galaxy S20 in 2020, Samsung offered 15W wireless charging across its flagships—until now.

• The Galaxy S26, S26 Plus, and especially the S26 Ultra are set to receive significant wireless charging upgrades.
• This marks a major shift for users who’ve long desired faster, more efficient wireless power delivery.

Galaxy S26 and S26 Plus: Up to 20W Wireless Charging

The standard and Plus models of the Galaxy S26 lineup will see an upgrade from 15W to 20W wireless charging.

• This 33% improvement will shorten charge times and enhance overall user convenience.
• It’s a notable step up for users sticking with the non-Ultra variants, especially those relying on wireless pads or docks daily.

Galaxy S26 Ultra: Supercharged with 25W Wireless

The Galaxy S26 Ultra is taking the biggest leap yet—supporting 25W wireless charging, which is a 40% improvement over its predecessor.

• This slashes the full wireless charge time from 100 minutes (S25 Ultra) to just 60 minutes (S26 Ultra).
• It places Samsung closer to competitors who have already embraced higher wireless speeds.
• Users can expect faster top-ups, especially valuable for professionals and power users.

The Engineering Behind the Speed

To support this faster wireless performance, Samsung made hardware-level enhancements.

• The wireless charging coil has been enlarged, allowing for greater current flow and heat management.
• The company has also adopted the Qi2 standard, a magnetic alignment technology that ensures efficient, reliable wireless charging.
• With Qi2 magnets now built directly into the back panel, there’s no need for special accessories or magnetic cases.

A Milestone Since Galaxy S20

This is Samsung’s first major wireless charging speed upgrade since 2020, when 15W wireless charging debuted on the Galaxy S20 series.

• The same speed persisted through the S25, Z Fold 7, and Z Flip 7, creating a long-standing limitation.
• With the S26 series breaking the cycle, the upcoming foldables may finally follow, potentially receiving at least 20W wireless charging.

What This Means for Users

The upgrade represents a major quality-of-life improvement, especially for users who depend on cable-free charging.

• Faster, reliable wireless charging without overheating issues is becoming a necessity with larger batteries and AI-driven tasks.
• The use of Qi2 also improves compatibility across devices and third-party chargers, making this update more accessible and future-proof.

Samsung is finally upgrading wireless charging in the Galaxy S26 lineup. The S26 Ultra leads with 25W wireless support, cutting charge time by 40%. Base models get 20W support, and all models adopt the Qi2 standard with enhanced coils for faster, more efficient power delivery.
