First details about Samsung’s highly anticipated new flagship series are beginning to emerge. Although not yet officially announced, the latest reports have revealed crucial clues about the Galaxy S26 battery specs and charging capabilities. Battery life and charging speed, two of the most critical features for users, appear to vary significantly across the Galaxy S26 lineup. Notably, the rumored 60W charging support for the Galaxy S26 Ultra, expected to be the most powerful model, could signal Samsung’s intent to step up its game in the competitive charging market.

Leaked Galaxy S26 Battery Specs Revealed

According to reliable sources, the Samsung Galaxy S26 family will consist of three models, each with distinct battery capacities and charging speeds. These leaks highlight Samsung’s segmentation strategy, offering different solutions for various user profiles. While the upgrade for the Ultra model is particularly noteworthy, the information about the standard model slightly contradicts earlier rumors. Here are the expected specifications for each model:

• Samsung Galaxy S26: The entry-level model is projected to feature a 4,300 mAh battery. Contrary to previous claims of 45W, this model is now expected to come with 25W fast charging support, which means it will retain the same charging speed as the S25 model.
• Samsung Galaxy S26 Plus: The mid-range Plus model is rumored to have a very competitive 4,900 mAh battery capacity and will support 45W fast charging technology. This promises a balanced user experience in terms of both capacity and speed.
• Samsung Galaxy S26 Ultra: The top-tier Ultra model is expected to keep its massive 5,000 mAh battery but will make a significant leap in charging speed. Leaks suggest the Galaxy S26 Ultra will offer 60W fast charging support, which would be the highest charging speed ever for a Samsung flagship phone.

These specifications also highlight the progress Samsung has made compared to the Galaxy S25 series. As a reminder, the Galaxy S25 featured 25W charging, while the S25 Plus and S25 Ultra models had 45W support. Therefore, the most significant advancement is undoubtedly expected in the new Ultra model.

Samsung is known for its more conservative approach to charging speeds compared to its rivals. In a market where some manufacturers have reached 100W and beyond, Samsung’s move to 60W represents a slow but steady step forward. This approach is likely rooted in the company’s strategy of prioritizing safety and long-term battery health. A 60W charging speed could allow users to charge their devices from 0% to around 70% in approximately 30-35 minutes, providing a major advantage for those with a busy lifestyle.

Processor Differences: Exynos vs. Snapdragon

The innovations in the Galaxy S26 series will not be limited to the battery. Leaks also provide important information about the processors that will power these devices. Samsung is expected to continue its traditional dual-processor strategy, which considers factors like performance-efficiency balance, regional variations, and cost optimization.

According to the rumors, the Galaxy S26 and Galaxy S26 Plus models will be powered by Samsung’s in-house Exynos 2600 processor, developed using a 2-nanometer (nm) manufacturing process. A smaller nanometer value theoretically translates to higher performance and lower power consumption. In addition, this could ensure that the 4,300 mAh and 4,900 mAh batteries last comfortably throughout the day.

In contrast, the top-of-the-line Galaxy S26 Ultra is said to use the Snapdragon Elite Gen 5 chipset, manufactured with 3nm technology, in the global market. As Qualcomm’s latest and most powerful processor, this chip is expected to offer groundbreaking features not only in raw processing power but also in AI capabilities and energy efficiency. The 3nm technology will enable more efficient use of the 5,000 mAh battery, potentially taking the Ultra’s battery life to the next level compared to its predecessor.
