Samsung’s penchant for sticking to a ‘safer’ approach for its flagship smartphones is undoubtedly one of the reasons why the company has fallen out of favor with consumers, losing its top spot to Apple. Even now, the Korean giant has limited the Galaxy S26 Ultra’s battery capacity to 5,000mAh, a figure that has been retained since the Galaxy S20 Ultra launch that happened six years ago. Naturally, we don’t expect the device to flaunt impressive runtimes, but one tipster says that we’re in for a pleasant surprise. Then again, the latest battery life comparison doesn’t put us at ease.
Battery life comparison between Galaxy S25 Ultra and Galaxy S26 Ultra reveals no change in video playback endurance
Prior to the Galaxy Unpacked announcement, the promo material for the Galaxy S26 Ultra shows that it will ship with the same 5,000mAh battery, which delivers the same 31-hour runtime in video playback as the Galaxy S25 Ultra. However, Weibo tipster Ice Universe (or Momentary Digital) makes a sketchy claim that there’s going to be a difference in the battery life, though he doesn’t highlight the changes that Samsung will make to ensure that customers are satisfied with their flagship purchase.
Some of the ways that the Galaxy S26 Ultra could reduce its power consumption are with its new M14 10-bit display, with the more efficient Snapdragon 8 Elite Gen 5 for Galaxy providing some decent breathing room. One thing to keep in mind is that when Qualcomm’s flagship chipset is stressed hard, it can get pretty toasty, and higher temperatures in a congested space can reduce the battery’s life and increase its discharge rate.
Fortunately, Samsung is rumored to utilize a larger vapor chamber to compensate for the Snapdragon 8 Elite Gen 5’s increased power draw. We also believe that Samsung’s continuous improvements to Galaxy AI will make battery management more intelligent.
Companies always boast legendary runtimes of their devices, but those results are obtained in highly controlled environments
It isn’t uncommon for companies like Samsung to make questionable claims about their devices’ battery life, and the majority of the time, flagship smartphones never make it close to the marketed endurance. The 31-hour video playback runtimes shared by the Galaxy S25 Ultra and Galaxy S26 Ultra shouldn’t necessarily highlight the lack of an upgrade; it could mean that Samsung is providing actual, real-world statistics that aren’t as far-fetched as the models that arrived previously.
Then again, we will wait for proper results to come through, then provide our verdict on whether the Galaxy S26 Ultra provides a meaningful upgrade in battery life compared to the Galaxy S25 Ultra.
