Get ready for a major Galaxy S26 Ultra battery disappointment

If that listing is authentic, and there’s no reason to believe it isn’t, it means the Galaxy S26 Ultra may feature the same 5,000 mAh battery as every top-tier Samsung flagship since 2020. Yeah, that’s not a typo – the Galaxy S20 Ultra, S21 Ultra, S22 Ultra, S23 Ultra, S24 Ultra, and S25 Ultra all had the same 5,000 mAh battery capacity.

While that may disappoint many Samsung fans, it’s not all bad news about the S26 Ultra battery. Earlier reports suggested that the device would support 60W fast charging, which would be a notable improvement over the 45W supported since the release of the S22 Ultra.

Samsung’s excuse for sticking with the same capacity for six years might be a combination of design concerns and optimizations. Just like every year, the combination of more efficient software and hardware could allow Samsung to squeeze more endurance from the same battery. On the other hand, the company might use a physically smaller battery with higher energy density and make the S26 Ultra much slimmer than previous models. All that’s just a speculation, but considering the company’s push to thin flagships with the S25 Edge, it makes sense.

I am firmly in the group of people who prefer a thicker device with a larger battery, and I believe we are a majority. However, providing a full day of autonomous work is what I need from my smartphone, and if Samsung can secure that with just 5,000 mAh, I’m down for a slimmer device. After all, Apple manages to squeeze fantastic endurance from the iPhone 16 Pro Max, and its battery is even smaller. So, Samsung needs to focus on efficiency and really deliver outstanding results or risk losing the trust of its most loyal fans.
