Samsung is set to continue utilizing a 5, 000mAh battery for its upcoming Galaxy S26 Ultra model. This decision indicates the company’s focus on harnessing more efficient hardware and optimizing software to enhance overall battery life compared to its predecessor, the Galaxy S25 Ultra. A noteworthy update is that Samsung will finally remove the restrictive fast charging access that has persisted in their flagship devices for years, as recent leaks suggest an exciting change for the Galaxy S26 Ultra.
Galaxy S26 Ultra Expected to Feature 60W Charging: A Major Upgrade Amid Battery Capacity Concerns
While Samsung has been investigating silicon-carbon technology to potentially enlarge battery sizes in future devices, reports indicate that the Galaxy S26 Ultra will maintain the same 5, 000mAh battery capacity as seen in previous models. Fortunately, a promising rumor has surfaced: instead of offering the standard 45W charging capability, the Galaxy S26 Ultra is anticipated to support impressive 60W fast charging, significantly reducing the time needed for battery replenishment.
Although rumors may lack substantiation without solid evidence, leaked code shared by tech enthusiast Erencan Yılmaz on X confirms the arrival of 60W charging for the Galaxy S26 Ultra. In a recent post, two lines highlight ’60W, ’ providing strong evidence that this sought-after specification enhancement is on the horizon for early next year.

As for the remaining models in Samsung’s Galaxy S26 lineup, details regarding their maximum charging capabilities have yet to be disclosed. Nonetheless, this development represents a promising improvement. Regarding how Samsung plans to enhance battery longevity with unchanged capacity, an executive previously mentioned that the company utilized AI technology in the Galaxy S25 Edge to increase efficiency. A similar strategy may be applied to the Galaxy S26 Ultra.
That said, there are limits to what software innovation can achieve, particularly if hardware remains static. It is crucial for Samsung to embrace silicon-carbon technology soon to remain competitive with its Chinese counterparts in the smartphone market.
