Samsung is gearing up to launch the Galaxy Tab S11 Ultra, and leaks suggest it will feature a slightly larger battery than its predecessor, the Tab S10 Ultra. 
Though the upgrade isn’t dramatic, it marks the first bump in battery capacity since the introduction of Samsung’s Ultra tablet series, starting with the Tab S8 Ultra.
According to new certification info, the Tab S11 Ultra will come with a rated battery capacity of 11,374 mAh, which translates to a typical (advertised) capacity of around 11,700–11,900 mAh. For comparison, the Tab S10 Ultra’s battery is rated at 10,880 mAh (typical: 11,200 mAh). It’s a modest increase, but in the world of high-performance tablets, even a few extra minutes of screen time can make a difference—especially for power users.
Why does it matter? Because high-end tablets are increasingly being used by artists, designers, students, and even gamers. While a powerful phone and laptop combo may cover most needs, a premium tablet can serve as a productivity and creativity tool, especially when paired with a stylus for drawing or note-taking. Casual users may find budget options under $200 sufficient for media consumption, but the Ultra series targets a more demanding audience.
That said, many users are hoping Samsung doesn’t stop at the battery. One consistent complaint about the Tab S10 Ultra was its display brightness, particularly in HDR mode. Competing devices like Xiaomi’s Pad Ultra and the iPad Pro M4 can reach HDR brightness levels of 1600 nits, while the S10 Ultra tops out at around 800 nits. If Samsung wants to remain competitive, an OLED panel upgrade is due.
Another eyebrow-raiser: the Tab S11 Ultra is rumored to be powered by MediaTek’s Dimensity 9400 chipset. While MediaTek has made major strides in performance, some fans expected a Qualcomm Snapdragon Elite platform for an ‘Ultra’ device. Still, Dimensity chips are known for efficiency, which might be part of the reason for the improved battery life.
In the end, the Tab S11 Ultra seems to be a step forward—just not a giant leap. More details should emerge as we get closer to the official launch, likely following Samsung’s typical fall release schedule.
And yes, the jump from Tab S10 to S11 may feel odd if you’re used to the Galaxy phone lineup skipping straight from S10 to S20. But tablet naming conventions play by different rules.

Was confused by the name-thought they skipped from S10 to S20 like phones lol
I don’t get the need for tablets tbh. Got a flagship phone + laptop already. 🤷
As long as it’s not over $1,200 and has a better display, I’m in
I use mine for drawing and note-taking mostly. Can’t imagine doing that with just a phone or laptop
Why they still using Dimensity in an Ultra model?? Snapdragon Elite would’ve made more sense. 🤔
OLED burn-in is real. 800 nits is fine for a 15” tablet you barely take outdoors
Not interested unless they bump the OLED brightness. Xiaomi and Apple are way ahead
