Highlights
- The Galaxy S26 Ultra is likely to retain its 5,000mAh battery, but may upgrade to 60W fast charging.
- The device is expected to be under 8mm thick, making it slimmer than previous Ultra models.
- Samsung may replace the floating lens layout with a unified camera island, enabling hardware upgrades to both sensors.

The rumours around the Samsung Galaxy S26 Ultra have been buzzing for months. Some leaks have previously suggested that the flagship model might finally get a bigger battery than Samsung’s usual 5,000mAh cell. However, the latest evidence indicates that Samsung may not be increasing the battery capacity after all. Here’s what we know so far.
Galaxy S26 Ultra – Hints About Possible Battery Specs

According to documentation spotted by SamMobile on China’s Quality Certification Centre, a battery with model number EB-BS948ABY has been listed with the standard 5,000mAh capacity. While the filing doesn’t explicitly confirm it belongs to the Galaxy S26 Ultra, the timing strongly suggests it.
This aligns with reports from some leakers who have insisted Samsung would stick with its tried-and-tested battery size rather than move to a larger 5,500mAh unit.
While the unchanged battery capacity might disappoint some fans, the Galaxy S26 Ultra is still expected to deliver an important upgrade. Several leaks point toward a bump in charging speeds from 45W to 60W, ending years of stagnation in this department. Notably, tipster Ice Universe has repeatedly dismissed rumours of a 5,500mAh cell, while confirming that Samsung is preparing faster charging for its Ultra model.
Keeping the 5,000mAh battery could also benefit the design. Reports suggest that the Galaxy S26 Ultra will measure under 8mm in thickness, making it slimmer compared to previous Ultra models. Meanwhile, Samsung is also expected to bring improved batteries to other models in the S26 lineup, with the Galaxy S26 Edge getting a 4,200mAh cell and the rumoured Galaxy S26 Pro equipped with a 4,300mAh battery.
Galaxy S26 Ultra Might Get New Camera Island Design

Meanwhile, design leaks suggest Samsung might revamp the camera module on the Galaxy S26 Ultra.
Samsung is reportedly considering an approach somewhat similar to what we have been hearing about Apple’s upcoming iPhone 17 Pro’s camera island. Instead of the separate floating lenses seen since the Galaxy S22 Ultra, the S26 Ultra may reintroduce a unified camera island design. This change could allow for hardware improvements to both the main and telephoto sensors.
In short, while the Galaxy S26 Ultra may not deliver the bigger battery many were hoping for, it could offer faster charging, a slimmer build and major camera island upgrades, making it one of Samsung’s most refined Ultra flagships yet.
