Galaxy S26 Ultra Leak Confirms Battery Reality: Same 5,000mAh Cell, Same 31-Hour Life

Even with 60W fast charging, the S26 Ultra will reportedly charge up to 75% in 30 minutes. Pictured: a leaked promo image of the phone.

Just days before Samsung’s highly anticipated Galaxy Unpacked event, a new leak has pulled back the curtain on the Galaxy S26 series—and it comes with a dose of reality for power users. While rumors have swirled for months about faster charging speeds and potential battery bumps, newly surfaced promotional materials confirm that the Galaxy S26 Ultra isn't budging from the status quo when it comes to endurance.

According to official-looking promo images shared by reliable tipster 🌟 너때문 🌟 on X, the Galaxy S26 Ultra will offer up to 31 hours of battery life. That figure is a carbon copy of what the Galaxy S25 Ultra promised last year, strongly suggesting that the new flagship will retain the familiar 5,000mAh battery capacity.

The 60W Charging Paradox

Perhaps the most confusing aspect of the leak revolves around charging speeds. The leaked promo material explicitly states that the Galaxy S26 Ultra can go from 0% to 75% in just 30 minutes. Interestingly, this is the exact same metric advertised for the previous generation.

This stagnation comes despite months of speculation suggesting a hardware upgrade. Earlier reports from leakers like Ice Universe claimed that Samsung was internally testing 60W fast charging for the Ultra model . If Samsung is indeed upgrading the internal hardware to support 60W (up from 45W), these leaked numbers imply that the real-world speed bump might be negligible—or that Samsung is being incredibly conservative with its marketing to prioritize battery health and thermal management.

For users still using older chargers, the difference might be minimal. If you are looking to upgrade your charging kit without breaking the bank, a reliable option like the 45W Iniu 10K power bank is currently available for just $19.98 on Amazon.

Camera Specs Finally Locked In

Aside from the battery debate, the leaked promo pictures reiterate the full camera specifications for the Ultra, putting months of speculation to rest. The Galaxy S26 Ultra appears to be sticking with a familiar yet refined setup:

  • Front: 12 MP selfie shooter
  • Rear (Wide): 200 MP primary sensor (rumored to feature a brighter f/1.4 aperture for improved low-light performance) 
  • Rear (Telephoto): 10 MP (3x optical zoom)
  • Rear (Periscope): 50 MP (5x optical zoom)
  • Rear (Ultrawide): 50 MP sensor

While the megapixel count on the primary sensor matches the S25 Ultra, the real upgrade is expected to come from software processing and the new, brighter aperture, which should allow the sensor to capture more light .

What’s Actually New?

If the battery and charging haven't changed, what has? The leaked materials and accompanying reports suggest that the Galaxy S26 Ultra will focus on display technology and AI.

The device is expected to debut with a new "Flex Magic Pixel" OLED display, which includes an AI-powered privacy feature that dims the content when viewed from an angle, preventing others from snooping on your screen in public . Additionally, the phone will be powered by the latest Snapdragon 8 Elite Gen 5 processor, which is built on a more efficient 3nm process. This chip efficiency might be Samsung's justification for sticking with the 5,000mAh cell, as the processor alone could extend daily usage despite the identical capacity rating .

Design and Pre-Orders

The leaked images also provide another look at the phone's design, showcasing a refined unibody look alongside the rumored Galaxy Buds 4 and Buds 4 Pro.

For those ready to upgrade, Samsung has already opened the reservation books. The official unveiling is set for February 25, 2026 in San Francisco . Customers who reserve a device now can unlock a $30 pre-order credit to use on Samsung.com.

The Verdict

It seems that Samsung is playing it safe with the S26 Ultra. While rivals push for 80W or even 100W charging and larger silicon-carbon batteries, Samsung appears to be doubling down on optimization and AI efficiency. Whether fans will accept the same battery specs for a third generation remains to be seen, but for now, the leaks suggest that the Ultra model remains a refinement, rather than a revolution.
