New Galaxy S26 leaks reveal bigger battery but no 25W charging upgrade
Recent information from the mobile technology industry indicates that Samsung plans to equip the entry-level model of the Galaxy S26 with a higher capacity battery, jumping to 4,300 mAh. Este represents a notable increase compared to the 4,000 mAh present in its predecessor, the Galaxy S25, promising superior autonomy for daily use.
Despite the improvement in battery capacity, wired charging speed for the base model will remain limited to 25 W. The expectation of an upgrade to 45 W, which would bring the device in line with its more powerful brothers, was discarded by reliable sources, who corrected the initial rumors circulating in specialized forums.
Samsung’s strategy appears to focus on software optimizations and processor energy efficiency to maximize charge durability, rather than betting on a drastic increase in recharge power for its most affordable model in the flagship line. The official launch of the new series is expected for an Unpacked event in February 2026.
Battery details across the entire S26 lineup
The differentiation between the Galaxy S26 series models will be clearly marked by battery and charging specifications. Enquanto the standard model will have 4,300 mAh and 25 W, the Galaxy S26+ should hit the market with a 4,900 mAh cell, maintaining support for 45 W fast charging, a configuration that seeks to balance performance with the need for a larger screen and more resources. Essa intermediate capacity is designed to ensure that the device can withstand a full day of intense use without difficulty, with the advantage of a significantly shorter recharge time compared to the entry-level model, completing the cycle in approximately one hour.

The big highlight is the Galaxy S26 Ultra, the top of the line in the family. Vazamentos point out that it will be equipped with a robust 5,000 mAh battery and, for the first time in the series, a 60 W fast charging system. Testes Preliminaries suggest that the device could reach around 75% of its charge in just 30 minutes, a crucial advance for the premium segment.

Samsung’s conservative charging strategy
Samsung’s decision to maintain the 25W charging speed on the base Galaxy S26, even in the face of an increase in battery capacity, reflects a calculated and conservative approach that prioritizes long-term component health and longevity. Engenheiros from the South Korean company believe that higher charging speeds can accelerate battery degradation over time due to the increase in temperature during the process. By limiting power, the company seeks to ensure that the battery maintains a charge retention capacity closer to ideal for more cycles, offering a more consistent user experience throughout the device’s useful life. Essa philosophy directly contrasts with that of many Chinese manufacturers, which already offer speeds above 100 W in their devices, but which may face questions about the durability of the components. The Samsung opts for a balance between convenience and reliability, positioning itself in a similar way to other market giants, such as the Apple and Google, which also adopt more moderate recharging powers in their flagships.
Rumor corrections and market dynamics
The first information that emerged about the Galaxy S26 line generated great expectations by suggesting that the entire series, including the entry-level model, would be standardized with 45 W charging. Essa news excited consumers who expected a complete technological alignment between the variants.
However, more recent sources with a history of success in the industry have corrected this information, confirming that the 25 W technology will be maintained for the standard S26. Essa change of route is common in the product development cycle, reflecting internal adjustments.
Such adjustments may be related to several factors, such as controlling production costs to maintain the entry model competitive, thermal management of the device to avoid overheating or simply a strategic decision to better segment the line’s products.
Advances in processors and the impact on autonomy
To compensate for the more modest charging speed in the base model, the Samsung invests heavily in the energy efficiency of the new processors. Especula It is expected that the Galaxy S26 and S26+ models will be equipped with the Exynos 2600 chip, built on the 2 nanometer process, which promises a significant reduction in energy consumption.

On the other hand, the Galaxy S26 Ultra must exclusively use an optimized version of the Snapdragon 8 Gen 5, focused on sustained performance and intelligent power management. The combination of more efficient hardware and larger batteries aims to extend actual usage time, making recharges less frequent.
