Samsung’s upcoming flagship, the Galaxy S26 Ultra, continues to make headlines as new leaks shed light on one of its most anticipated upgrades — the battery.
While earlier reports were conflicting, a fresh leak from China now suggests that the Galaxy S26 Ultra will indeed offer a modest boost in battery capacity.
According to the latest leak, the Samsung Galaxy S26 Ultra will come equipped with a 5,200mAh battery. Although this isn’t a major jump from the 5,000mAh battery used in several previous Ultra models, it still represents a meaningful improvement that could help extend daily usage, especially for power-hungry users.
However, this new claim doesn’t align with information revealed through a Chinese certification listing back in August. That certification stated the Galaxy S26 Ultra would feature a battery with a rated capacity of 4,855mAh, which typically corresponds to an advertised 5,000mAh typical capacity. With two opposing reports now in circulation, Samsung enthusiasts may need to wait for additional certifications or more reliable leaks to confirm the final battery size.
Leaked renders of the Galaxy S26 Ultra, shared by OnLeaks and AndroidHeadlines, have also surfaced alongside the battery news, giving fans an early glimpse at Samsung’s 2026 premium flagship. The design appears familiar yet refined, hinting at Samsung’s continued focus on durability and sleek aesthetics.
Beyond battery capacity, charging speed is another area expected to see a significant upgrade. Previous reports indicate that the Galaxy S26 Ultra may support 60W wired charging and 25W wireless charging.
This would mark a noticeable improvement over the Galaxy S25 Ultra, which offers 45W wired and 15W wireless charging. If accurate, these enhancements could reduce charging times considerably, making the S26 Ultra more convenient for users who rely heavily on fast power top-ups.
As always, with the launch still months away, these details remain unofficial. More leaks and certifications will likely emerge soon, helping paint a clearer picture of what Samsung has in store for its next-generation Ultra smartphone. For now, fans can look forward to a slightly larger battery and faster charging — upgrades that could make a meaningful difference in everyday performance.
