We are collecting more pieces about the Galaxy S26 Ultra. The manufacturer will bet on a completely different approach than the competition

  • According to leaks, the Galaxy S26 Ultra will feature a battery with the same 5000 mAh capacity but higher energy density
  • The main camera is expected to retain the 200 Mpx resolution, but it is unclear whether it will be a new sensor
  • Samsung will likely implement faster charging and a thinner body thanks to a more space-efficient battery design

Although there is still more than half a year until the presentation of the Samsung Galaxy S26 series, the first credible information leaks are already appearing online. This time, we learn details about two key specifications of the upcoming top model Galaxy S26 Ultra – its battery and main camera. While at first glance it may seem that Samsung is preparing more of an evolution than a revolution, the details suggest interesting improvements in the area of energy efficiency.

Battery: same capacity, higher density

According to information from reputable leakers, the battery capacity in the Galaxy S26 Ultra will remain at the same value of 5000 mAh, which we already know from several generations of top models, including the current S25 Ultra. However, this does not mean that nothing will change in the area of power. IceUniverse claims that the new battery will have significantly higher energy density, which in practice means that while maintaining the same capacity, it will take up less space in the device’s body.

Samsung will likely not use this gained space to increase capacity, but rather to further slim down the phone’s body. This is a completely different approach than that of Chinese competitors and suggests that the Korean manufacturer considers the current 5000 mAh sufficient for all-day endurance and prefers to focus on design.

The positive news is that the S26 Ultra could finally offer faster charging. Although the leaker did not provide specific values, they mention that Samsung will likely implement a new technology that will enable faster charging thanks to better thermal management. The current S25 Ultra supports charging up to 45 W, which is still a relatively conservative value compared to competitors from China.

Camera: 200 Mpx remains the standard

Regarding the camera, a source from GalaxyClub states that the main sensor will retain the 200 Mpx resolution, just like the Galaxy S25 Ultra. However, it is not clear whether Samsung will deploy a completely new sensor or an improved version of the existing one. For users, it would naturally be more beneficial if the manufacturer implemented a newer generation sensor with better light and detail processing.

It is important to remember that the same resolution does not mean the same photo quality – Samsung can improve image processing at the software level or add new features using artificial intelligence. In recent years, we have seen that software and AI play an increasingly important role in photography than the hardware specifications themselves, although they naturally also have their limitations.

Information about the other cameras is still missing. We can only speculate whether Samsung will retain four sensors, including a pair of telephoto lenses, or come up with some surprise; personally, I would appreciate, for example, an improved ultrawide sensor.

We will wait for other specifications

Given that there are more than six months left until the presentation of the Galaxy S26 series (expected in January 2026), it is natural that most specifications remain shrouded in mystery. In the coming months, we will certainly learn more about the processor used, the display, RAM, and other key parameters.

From the leaks so far, it seems that Samsung is betting on a proven strategy of gradual improvements for its flagship model rather than radical changes. From a certain perspective, this makes sense, as the Galaxy S25 Ultra is already an excellent phone that in many respects does not have significant shortcomings that would need urgent addressing.

For those who do not want to wait for the S26 series, Samsung will introduce new foldable phones next week, the Galaxy Z Fold 7 and Galaxy Z Flip 7, where significant innovations are expected, especially for the Fold, which will be thinner and offer a more pleasant aspect ratio for the front display.

What would you improve on Samsung’s current TOP flagship?
