If you were expecting a big battery in Samsung’s next flagship, then prepare to go down. The Galaxy S26 Ultra, South Korean tech veteran’s upcoming next-round flagship, is glued to the same 5,000mAh battery that has been used for the last six years. This is correct, there is no upgrade in capacity, even in 2025. But do not remove your pitchforce yet. While the number has not changed, what can happen inside that number. According to the reliable tipster Universe Ice, Samsung may have found a clever workaround: instead of increasing the size, they have possibly improving the energy density of the battery. In simple terms, this means that the same power in more compact package.

Benefit? A phone that is both thin and light, without compromising on battery life. This can be a welcome change for those who have felt the ultra model growing over the years. S26 Ultra can be just a smooth, more pocket-friendly powerhouse.

Samsung Galaxy S26 Ultra: Battery Leakes

But perhaps the real head-ender is rumored about charging speed. Samsung is known to be conservative when it comes to rapid charging, then it may finally be ready to pursue the boundaries. Tipster, Universe ice, suggests that the company is testing a new charging technology that keeps the phone cooler during power-up, one of the major obstacles to enabling rapid charging without affecting the battery damage or without affecting the performance.

If leaks are accurate, this new system can see Samsung a leap from its current 45W standard, which can make at least 65W fast charging on the Galaxy S26 Ultra. It is a major jump for Samsung, it has been kept close to rivals such as OnePlus and Xiaomi, which have moved forward in the charge department for a long time.

To keep things in perspective, the Samsung Galaxy S25 Ultra 45W packs 5000mAh battery with fast charging support. While the capacity of the battery cannot change for the upcoming Galaxy S26 Ultra, the charging speed may increase to 65W. Overall, it will charge the upgrade device very rapidly and can provide a sharp power top-up than its predecessor.

If the leak is accurate, the Galaxy S26 Ultra can be one of the best balanced Samsung flagships, offering power, portability and speed in a streamlined package. It may be that the upgrade fans were dreaming, but it is still getting excited.

Samsung Galaxy S26 Ultra Camera Bump

We talked about how Samsung Galaxy S26 is working to make ultra slimmer. But this is not only due to the battery, the camera collision is also expected to change, and for better.

Samsung may be ready to deal with one of the most complained designs Quirks-Chunky Camera Bump. Word is, the Galaxy S26 Ultra will feature a new inkjet-printed anti-ending layer instead of the general thin cover movies between the lenses. This clever swap allows Samsung to dilute the camera module without renouncing image quality.

Result? A smooth, more streamlined phone that does not stagger on flat surfaces or feels heavy in the hand. This is a win for both form and function.

Interestingly, Samsung patented this technology back in 2018, and it seems that it is finally ready for prime time. If true, it can be one of the most subtle but impressive upgrades that the ultra series has seen over the years.
