Samsung Galaxy S26 Ultra to Feature Bigger Battery and Breakthrough 65W Charging
Samsung is preparing to raise the bar once again with the upcoming Galaxy S26 Ultra, rumored to arrive early next year. While the competition, particularly from Chinese brands, is pushing boundaries with larger batteries and ultra-fast charging, Samsung appears ready to respond.
According to a recent leak, the Galaxy S26 Ultra is set to pack a 5,500mAh battery, a modest yet meaningful upgrade over the 5,000mAh cell in the S25 Ultra. This 10% increase could translate to longer screen time, especially when paired with Samsung’s software optimization and energy-efficient display technologies.
But the real headline lies in the charging capabilities. For the first time, a Samsung smartphone is expected to support 65W wired fast charging, moving beyond the long-standing 45W limit that has capped recent Galaxy models. This is a significant step forward for the brand, placing it closer to rivals that offer 80W or even 100W charging in flagship phones.
In addition to wired improvements, the S26 Ultra is also rumored to support 25W wireless charging via the new Qi2 standard. If accurate, this would mark the fastest wireless charging ever on a Samsung smartphone, offering faster top-ups even without cables.
Surprisingly, despite the larger battery, the S26 Ultra is expected to be thinner than the S25 Ultra, which measured 8.2mm in thickness. If true, this speaks to Samsung’s design advancements, delivering more power in a sleeker body.
Key Rumored Upgrades for the Galaxy S26 Ultra:
Battery: 5,500mAh (vs. 5,000mAh in S25 Ultra)
Wired Charging: 65W Fast Charging (first-ever for Samsung)
Wireless Charging: 25W Qi2 support
Design: Thinner than 8.2mm
While these are early leaks and subject to change, the improvements signal Samsung’s intent to stay competitive in the rapidly evolving flagship market.
Conclusion:
The Galaxy S26 Ultra could be the power upgrade Samsung fans have been waiting for. With a larger battery, significantly faster charging speeds, and a slimmer design, it’s shaping up to be a major leap over its predecessor. As we await its official reveal, all eyes are on how these rumored specs will translate into real-world performance.
