Galaxy S27 Pro/Ultra TUV Certifications Reveal Exact Battery Capacity
Our newsroom has obtained fresh documentation from the TUV certification authority that lists the precise battery capacity for the upcoming Galaxy S27 Pro and Galaxy S27 Ultra. The filings, which are typically submitted ahead of market launch, provide the first hard numbers for the power cells that will drive Samsung’s next flagship duo.
The information is still classified as an industry leak, and Samsung has not made an official statement. However, the certification data is considered reliable enough for analysts to begin modeling the devices’ endurance and charging behavior.
Here is a quick overview of the key points:
Certification Details
The TUV submission includes model identifiers that match the previously rumored SM-S928 and SM-S926 designations. According to the filing, the Pro variant is listed with a rated capacity of 4,800 mAh, while the Ultra variant shows a slightly larger 5,000 mAh cell. These figures are consistent with the incremental upgrades Samsung has introduced in recent generations.
Because the certification is still pending final approval, the exact energy density and chemistry remain unspecified. Industry observers caution that the final retail version could differ by a few percent, but the current numbers provide a solid baseline for comparing the two models.
Battery Specifications
The 4,800 mAh battery in the Pro is expected to support 45 W wired fast charging, as well as 15 W wireless charging and 4.5 W reverse wireless charging. The Ultra’s 5,000 mAh unit is rumored to enable 50 W wired charging, alongside 25 W wireless and 5 W reverse charging, though these charging speeds have not been confirmed by the manufacturer.
Both devices are anticipated to run on the latest version of One UI, which includes adaptive battery management that can extend screen-on time by up to 10 percent compared with previous models. The combination of larger cells and optimized software could push daily usage beyond the 24‑hour mark for most users.
Market Impact
Analysts estimate that the Galaxy S27 Pro could be priced around €999, while the Ultra model may start near $1,099, reflecting the premium materials and advanced camera system that accompany the higher capacity. These price points place the new flagships in direct competition with other high‑end devices from rival manufacturers.
The introduction of a 5,000 mAh battery in the Ultra tier signals Samsung’s focus on endurance, a feature that has become a key selling point for power users. If the rumored charging speeds hold true, the S27 series could set a new benchmark for fast‑charging performance in the Android ecosystem.
Competitive Landscape
Competing devices such as the upcoming OnePlus 12 and the Xiaomi 13 Pro are also expected to feature batteries in the 4,800–5,000 mAh range, but Samsung’s integration of a custom power management integrated circuit may provide an edge in efficiency. The TUV certification gives Samsung a first‑mover advantage in publishing concrete capacity figures, which could influence consumer perception.
Moreover, the certification highlights the industry’s shift toward larger cells without compromising device thickness. Both the Pro and Ultra are rumored to maintain a profile under 8 mm, a balance that other manufacturers have struggled to achieve while increasing battery size.
What Lies Ahead
Looking ahead, the confirmed capacities suggest that Samsung is preparing to address the growing demand for all‑day battery life, especially as 5G and high‑refresh‑rate displays become standard. The company’s investment in fast‑charging technology could also spur adoption of higher‑wattage chargers across the market.
As the launch window approaches, we expect additional leaks regarding display specifications, camera sensors, and software enhancements.
