A new TUV certification has revealed the battery specifications for the upcoming Samsung Galaxy S26 Plus. The listing shows a rated capacity of 4,755mAh, identical to its predecessor, the Galaxy S25 Plus. Additionally, the phone will support 45W wired charging, again mirroring last year’s model. This news may disappoint users hoping for a battery boost in the new midsize flagship.
Certification Details and Model Identification
The certification entry, spotted by The Tech Outlook, lists model number SM-S947B/DS. Previous leaks confirm this corresponds to the Galaxy S26 Plus. The document specifies a lithium-ion battery with the 4,755mAh rating. Samsung typically markets a slightly higher “typical” capacity; therefore, we can expect an advertised capacity around 4,900mAh, just like the S25 Plus.
Charging Speeds: Wired Confirmed, Wireless Unclear
The TUV certification confirms the 45W maximum wired charging speed. However, it does not detail wireless charging capabilities. Rumors suggest the entire S26 series could introduce magnetic Qi2 wireless charging support. A separate certification in December 2025 for a “Samsung Magnet Wireless Battery Pack” hints at this move. It remains unclear whether the S26 Plus would support the standard Qi2 15W or faster Qi2 25W charging.
Context and Market Expectations
With an expected launch as soon as February, this certification provides concrete hardware details. The lack of progression in battery capacity or wired charging suggests Samsung may be focusing upgrades elsewhere—potentially on display efficiency, chipset performance, or software optimization. For users, this means battery life will likely rely more on the efficiency of the new Snapdragon 8 Elite Gen 4 or Exynos 2600 processor rather than a larger cell.
The Potential for Qi2: A Silver Lining
The possible addition of Qi2 magnetic wireless charging would be a notable quality-of-life improvement. It would offer more reliable alignment and potentially faster wireless speeds than standard Qi. This could partially offset the disappointment of unchanged wired charging and battery capacity.
Iterative Battery Specs, Potential for Efficiency Gains
The TUV certification paints a picture of battery and charging continuity for the Galaxy S26 Plus. While the specs show no increase, real-world battery life could still improve through more efficient components. The potential inclusion of Qi2 wireless charging remains the most exciting unknown. As more certifications emerge, we will gain a clearer picture of whether Samsung is playing it safe or hiding more significant upgrades under the hood.
