Samsung Confirms 45W Super Fast Charging for Galaxy Tab S11 Ultra

Samsung has officially confirmed the charging capabilities of its upcoming flagship tablet, the Galaxy Tab S11 Ultra. The device, part of the 2025 Galaxy Tab S11 lineup, continues the brand’s tradition of combining large battery capacity with efficient fast-charging technology. The confirmation of a 45W charging speed puts to rest months of speculation about whether Samsung would finally adopt a faster wattage for its ultra-premium tablet.

The Galaxy Tab S11 Ultra features an enormous 11,600mAh battery, designed to power its expansive 14.6-inch Dynamic AMOLED 2X display and powerful MediaTek Dimensity 9400+ chipset. Samsung has officially stated that the tablet supports 45W Super Fast Charging, the same standard found in previous models like the Tab S9 Ultra and the Galaxy S24 Ultra smartphones. While some users were expecting an upgrade to 65W or 80W charging, Samsung has chosen to retain the tried-and-tested 45W system, prioritizing safety, battery longevity, and heat efficiency over raw charging speed.

In practical terms, the 45W charger allows the Galaxy Tab S11 Ultra to charge from 0% to around 50% in approximately 40 minutes and to full capacity in about two hours, depending on usage and conditions. For a battery of this size, these times are reasonable, especially considering that Samsung’s adaptive power management optimizes the charge cycle to prevent degradation over long-term use. The company has consistently emphasized that its Super Fast Charging 2.0 technology balances power delivery and temperature control to enhance user safety and battery health.

The Galaxy Tab S11 Ultra’s massive battery is designed to handle high-demand activities such as multitasking, video editing, and extended media consumption. With its 14.6-inch display running at a 120Hz refresh rate, the tablet consumes significant power during intensive use. However, early reports suggest that the power efficiency of the Dimensity 9400+ processor and Samsung’s One UI 8 optimizations on Android 16 help maintain strong endurance. Users can expect up to 12–14 hours of mixed-use time, depending on brightness levels and app load.

Samsung has also continued its approach of not including a charger in the box, a decision consistent with the company’s sustainability initiatives. Users will need to purchase the 45W charger separately if they don’t already own one. This policy aligns with Samsung’s push to reduce electronic waste and carbon emissions, although it remains a topic of debate among consumers. For those who already use Samsung devices with 45W charging support, the same adapter can be used seamlessly with the Galaxy Tab S11 Ultra.

The charging port remains a USB-C 3.2 Gen 2 interface, which supports fast data transfer and external display connectivity via Samsung DeX. This allows users to quickly switch between tablet and desktop modes, making the device suitable for both productivity and entertainment. The tablet’s charging system also supports reverse charging, enabling it to power accessories like Galaxy Buds or smartwatches through the USB-C connection.

Samsung’s decision to retain the 45W charging speed is based on a balance between performance and reliability. While competitors such as Xiaomi, OnePlus, and Realme have introduced tablets with 65W to 100W fast charging, Samsung continues to emphasize safety standards and consistent charging performance. The company’s advanced battery protection algorithms prevent overheating and voltage spikes, which can affect long-term battery health. This conservative approach ensures that the Galaxy Tab S11 Ultra remains dependable for years of heavy use, which is a key factor for professional users.

Another notable feature is the tablet’s ability to maintain cool temperatures during charging, even when multitasking or using high-performance modes. The internal vapor chamber cooling system works in tandem with the power management chip to distribute heat evenly. This thermal control ensures stable performance during intensive workloads like 3D rendering, video playback, or gaming, even while charging.

For productivity users, the combination of a large battery and consistent fast charging makes the Galaxy Tab S11 Ultra a reliable companion for work and travel. It can power through a full day of meetings, creative work, or content streaming without frequent recharging. The inclusion of 45W Super Fast Charging ensures that even short charging sessions can provide several hours of use, which is ideal for users who are often on the move.

In conclusion, the Samsung Galaxy Tab S11 Ultra’s confirmed 45W charging speed reflects the company’s focus on balance rather than sheer speed. While it may not boast the highest wattage in the tablet market, the charging system is optimized for long-term performance, safety, and efficiency. Combined with its large 11,600mAh battery, advanced cooling system, and efficient chipset, the Tab S11 Ultra promises to deliver a dependable power experience for both professionals and entertainment enthusiasts. Samsung’s emphasis on stability and user protection continues to define its premium devices, and the Tab S11 Ultra stands as a prime example of this philosophy in 2025.
