Posters that surfaced online ahead of the February 25 Unpacked event show Samsung claiming up to 31 hours of video playback on a single charge. That’s the exact same figure the company advertised for the Galaxy S25 Ultra.
While advertised playback time doesn’t technically confirm the battery capacity, it does make a larger cell unlikely. The new Snapdragon 8 Elite Gen 5 is rated for notable efficiency gains, with improvements in CPU and GPU power efficiency, better sustained SoC power savings, and stronger performance per watt for AI tasks. In theory, that means the chip should draw less power for everyday workloads compared to last year’s model.
Video playback in particular is a relatively light, steady task that doesn’t push peak performance limits. If the processor is indeed more efficient, matching last year’s 31-hour figure strongly suggests the battery capacity remains at 5,000mAh.
Charging doesn’t look dramatically different either
The posters highlight 0 to 75 percent in 30 minutes, which again mirrors last year’s Ultra. There have been whispers of a move to 60W wired charging, up from 45W on the S25 Ultra, but if the real-world time to 75 percent hasn’t changed, the difference may be more technical than practical. Thermal limits and battery longevity tuning often cap the visible gains from higher wattage. In other words, if you were expecting a major battery leap, this may not be it.
That said, the leaked materials do confirm a few other details. The rear camera setup appears largely unchanged on paper: a 200MP main sensor, 50MP ultrawide, 50MP 5x periscope telephoto, and a 10MP 3x telephoto. The front camera is listed at 12MP with autofocus.
Samsung is also promoting a new “Privacy Display” feature, which reportedly reduces screen visibility from side angles. It’s one of the few new additions being highlighted in the early marketing material.
On paper, the S26 Ultra looks more like a refinement than a dramatic overhaul. Whether optimization in One UI 8.5 makes up for the lack of bigger numbers is something we’ll find out once real-world testing begins.
