New Galaxy S26 Ultra leak busts 7,000mAh battery rumor

Earlier this week, we learned that Samsung will use the silicon-carbon chemistry for the battery of its non-foldable flagship smartphone for 2026, the Galaxy S26 Ultra, to pack it with a capacity between 6,000mAh and 7,000mAh. While it put a huge smile on the faces of Samsung fans, it sounded too good to be true and a new leak suggests that is what it was, too good to be true.

On X, @PandaFlashPro claims that Galaxy S26 Ultra’s battery will definitely not have a capacity between 6,000mAh and 7,000mAh. Instead, its battery will have a maximum/typical capacity of 5,500mAh and a rated capacity of 5,396mAh.

While the news shatters the happiness that the previous leak had given to people, a 5,500mAh battery is a respectable 10% larger than that of the Galaxy S25 Ultra. The current model already offers better battery backup than most of its rivals that have a larger battery. It means that the upcoming model with a 10% larger battery pack should help it gain the top position on the chart.

Here's what we know about the Galaxy S26 Ultra so far

According to previous leaks, the Galaxy S26 Ultra will feature a Qualcomm Snapdragon SoC (most likely the successor to the Snapdragon 8 Elite). Its display will be brighter and more efficient than the one on the current model and it will have an under-display camera too.
