Samsung is poised to break its long-standing 5,000 mAh battery barrier on its flagship Galaxy series. New leaks suggest that the upcoming Galaxy S26 Ultra will ship with a larger 5,200 mAh battery, marking the biggest battery capacity in a mainstream Samsung phone in recent years.
Galaxy S26 Ultra Packs 5,200 mAh Battery and 60W Fast Charging
According to translated leaks, the Galaxy S26 Ultra will continue the trend of becoming slimmer and lighter than its predecessors, but with a notable upgrade in battery capacity. The phone will feature a 5,200 mAh battery instead of the 5,000 mAh unit that has been standard in Samsung’s high-end devices for several generations.
In addition to the bigger battery, the Galaxy S26 Ultra is expected to support faster charging speeds of up to 60W, which is a significant enhancement and very much welcomed by users who demand quicker top-ups.
These upgrades come as Samsung aims to better compete with rival Apple’s iPhone 17 Pro Max, which continues pushing benchmark performance and battery efficiency.
Competition with iPhone 17 Pro Max Driving Improvements
The decision to increase the battery capacity on the Galaxy S26 Ultra appears to be closely tied to market competition, especially against Apple. The iPhone 17 Pro Max remains a strong competitor, and Samsung seems determined to maintain an edge by offering not just comparable but improved battery performance and charging capabilities.
Insights from Galaxy S26 Edge May Influence Design
Leaked information also points to the Galaxy S26 Edge – a model rumored to have been cancelled – as a developmental influence. Samsung reportedly encountered limits with lithium-ion battery technology during the design of the S26 Edge but has likely applied these learnings to optimize the S26 Ultra’s design. This explains how Samsung managed to slim down the device's profile while increasing battery capacity.
Industry trends show a growing emphasis on balancing slimmer phone designs with more robust hardware and longer-lasting batteries. Samsung's push toward better battery technology reflects this shift and shows promise for consumers seeking a more powerful yet sleek smartphone experience.
