Evidence found in a preliminary version of the Samsung operating system suggests a significant evolution in wireless charging technology for the brand’s future generation of smartphones. Análises detailed code for One UI 8.5, software that should debut with the Galaxy S26 line, points to the implementation of wireless charging with a power of 25 watts, a notable advance over the 15 watts offered in current models.
The discovery, made by software analysts who investigated the firmware, raises expectations for devices expected in early 2026. Essa update would put the South Korean manufacturer in a more competitive position in the premium device market, where charging speed has become a decisive factor for many consumers.
In addition to the power increase, the code also references the adoption of the Qi 2.2 standard, a new specification that uses magnetic alignment to optimize energy transfer. The technology promises not only faster recharges, but also more efficient and safer ones, minimizing heating and preserving battery life.
Details revealed in the system code
The most concrete evidence about technological advancement was located in specific lines of code in the firmware. Desenvolvedores identified direct mentions of a new charging category, called “Super fast wireless charging”, which would join the charging modes already existing in the brand’s devices.
This new speed rating suggests that future Samsung devices will be able to differentiate between standard wireless charging, 15-watt fast, and the new 25-watt super-fast mode. The presence of these references natively in the operating system indicates that the resource is in an advanced stage of development to be integrated into the final hardware.
Code analysis also reinforces compatibility with the Qi 2.2 standard, a protocol that relies on magnets to ensure perfect alignment between the smartphone and the charging base. Isso suggests that the Galaxy S26 line could be the first of the Samsung to incorporate a magnetic system similar to the Apple’s MagSafe, opening doors to a new ecosystem of accessories.
Segmentation strategy for the S26 line
The leaked information points to a clear differentiation of resources within the Galaxy S26 family. The Ultra model should be the main beneficiary, receiving exclusively 25-watt wireless charging technology, which will work together with a battery whose capacity is estimated at 5,000 mAh.
This combination has the potential to drastically reduce the time of a full wireless charge, possibly to less than an hour and a half, offering unprecedented convenience for the brand’s users.
For models Galaxy S26 and Galaxy S26 Plus, Samsung must promote a more contained upgrade. The expectation is that both devices will support wireless charging of up to 20 watts, an improvement over the 15 watts of the previous generation, but still below the most expensive model.
This strategy allows the company to balance the offer of new technologies with the production costs of each device, reinforcing the positioning of the Ultra model as the product aimed at consumers seeking maximum performance and innovation.
The importance of adopting the Qi 2.2 standard
The transition to the Qi 2.2 standard represents much more than a simple increase in reload speed. Essa technology is designed to improve energy efficiency by up to 20% when compared to previous standards, as precise magnetic alignment minimizes energy losses during the transfer process. The practical result is the generation of less heat, which contributes to a safer recharging process and preserves the integrity of the battery in the long term, delaying its natural degradation.
For this technology to be implemented, Samsung will need to integrate magnetic rings into the chassis of devices in the Galaxy S26 line. Essa structural change will allow smartphones to firmly connect to compatible chargers and accessories, such as car mounts, magnetic wallets and power banks. The measure significantly expands functionality and convenience for the user, creating a robust and interconnected ecosystem of accessories, similar to what is already seen in other brands on the market.
Advances also in wired charging
In addition to notable improvements in wireless charging, the Galaxy S26 series is expected to bring significant advances in cable charging, with a special focus on the Ultra model. Consistent Rumores indicate the implementation of Super Fast Charging 3.0 technology, which would increase maximum power to 60 watts. Este system uses the PPS (Programmable Power Supply) protocol to dynamically adjust voltage and electrical current, intelligently optimizing power delivery and controlling the device temperature to prevent overheating. Testes preliminary prototypes suggest that this power would be capable of charging around 50% of the battery in approximately 20 minutes, an extremely competitive mark in the current scenario of high-end smartphones. While some rival manufacturers already offer speeds in excess of 80 watts, the Samsung’s approach has historically been more conservative, prioritizing safety and battery durability. The company seeks a balance between recharging performance and component longevity, avoiding excessive thermal stress that can degrade battery capacity over time. The jump to 60 watts, combined with the innovation of the Qi 2.2, demonstrates a calculated strategy to innovate without compromising the reliability that is the hallmark of the Galaxy line.
What else to expect from the Galaxy S26 Ultra
The Galaxy S26 Ultra must maintain the line’s established visual identity, but with important refinements in its design and construction. Vazamentos of renders indicate a thinner titanium chassis, with a thickness of 8.2 mm, without sacrificing the IP68 certification for water and dust resistance.
The rear camera array will continue to be one of the main attractions, possibly with an improved 200-megapixel main sensor and a new 50-megapixel telephoto lens for high-quality zoom.
End of a long period of stagnation
The decision to increase wireless charging power is a milestone for Samsung, which has maintained a 15-watt limit on its high-end models since the launch of the Galaxy S20 in 2020. For years, the company has taken a cautious stance, focusing on longevity and safety testing to avoid overheating issues.
This stagnation, however, generated criticism from consumers and experts, who saw the South Korean manufacturer falling behind competitors that already offered much faster recharging technologies. With the maturity and standardization of Qi 2.2, Samsung appears to have found a safe path forward.
New ecosystem of magnetic accessories
The introduction of 25-watt charging and the Qi 2.2 standard in the Galaxy S26 line is expected to boost the entire ecosystem of accessories from Samsung and partner companies, creating new market opportunities and greater convenience for users.
