Premium Samsung tablet leaks with display and battery details

The Galaxy Tab S series is Samsung's flagship lineup of tablets. The Galaxy Tab S11 series launched in September 2025 with two models: the Galaxy Tab S11 and the Galaxy Tab S11 Ultra.

A previous leak revealed that Samsung may not release the standard Galaxy Tab S12 this year. Instead, the company may reportedly launch the Galaxy Tab S12+ and the Galaxy Tab S12 Ultra with model numbers SM-X846 and SM-X946, respectively.

Now, a leak from GalaxyClub.nl has revealed additional details about the Tab S12 Ultra. The publication notes that the next-generation Tab S12 Ultra may retain a similar battery capacity to its predecessor. The source hints that the charging speed could also remain unchanged at 45W. For context, the Tab S11 Ultra (curr. $1,120 on Amazon) features an 11,600mAh battery. 

The leak also suggests that the Galaxy Tab S12 Ultra may retain the 14.6-inch display size of the Tab S11 Ultra. The Galaxy Tab S12 Ultra may use a flagship MediaTek Dimensity chipset, potentially the Dimensity 9500.

Samsung is expected to release the Galaxy Tab S12 series in September 2026. Since all the above information is based on a leak, it should be treated with caution.
