With just days to go before Samsung’s next Unpacked event, a fresh batch of leaked promotional images has seemingly confirmed what many were wondering about the Galaxy S26 Ultra: battery life and charging may not see a meaningful upgrade in 2026.
The leak, shared on X by tipster @ya_sking12767, includes official-looking marketing slides for the Galaxy S26 lineup, including the base model, S26+, and Galaxy S26 Ultra, alongside the new Galaxy Buds 4 series. And while there is plenty of Galaxy AI branding and camera hype, the battery story looks very familiar.
Here’s what the leaked promo materials reveal.
Galaxy S26 Ultra battery still 5,000mAh
According to the leaked spec breakdown, the Galaxy S26 Ultra retains the same 5,000mAh battery capacity as its predecessor.
Samsung reportedly claims up to 31 hours of battery life, which is also unchanged year over year. If accurate, this suggests that while efficiency gains may come from the new chipset, there’s no increase in raw battery capacity.
For a flagship in 2026, that might disappoint some users hoping for a bump to 5,500mAh or higher, especially as competitors continue pushing battery innovation.
That said, real-world endurance will ultimately depend on software tuning, AI workload optimization, and display efficiency.

Charging speed: 75% in 30 minutes
The leaked promo slide also claims that the Galaxy S26 Ultra can charge to 75% in 30 minutes.
If that sounds familiar, it’s because it mirrors last year’s figures. While there have been rumors suggesting a possible shift to 60W charging, the marketing numbers do not suggest a dramatic improvement in real-world charging time.
If Samsung has increased peak wattage, it may not translate into noticeably faster top-ups, at least based on these promotional claims.
In short, battery and charging appear steady rather than revolutionary.
Privacy Display shown in more detail
One of the more visually interesting parts of the leak highlights the new Privacy Display feature.
The promo image shows the entire screen darkened when viewed from an off-angle, suggesting a full-screen privacy mode. However, earlier leaks hinted at more granular control, potentially allowing users to apply privacy shielding to specific areas like notifications.
Whether Privacy Display is all-or-nothing or selectively configurable remains unclear, but Samsung appears to be positioning it as a key differentiator in 2026.
Camera hardware remains familiar
The Galaxy S26 Ultra’s camera layout appears unchanged on paper:
- 200MP primary sensor
- 50MP 5x telephoto
- 50MP ultrawide
- 10MP 3x telephoto
- 12MP front-facing camera
Samsung is instead leaning heavily into AI enhancements. Promotional materials emphasize Galaxy AI branding and showcase prompt-based image editing through Photo Assist. Samsung previously teased that editing tools would feel more integrated directly within the camera experience this year, rather than existing as separate post-processing steps.
The hardware may be familiar, but the computational layer is clearly the focus.
Snapdragon upgrade under the hood
As expected, the Galaxy S26 Ultra will ship with the latest Snapdragon chipset, promising improved performance and efficiency. While the leak does not specify benchmark numbers, performance gains are a given in each annual refresh cycle.

The key question will be whether efficiency improvements meaningfully extend battery endurance beyond Samsung’s advertised 31-hour figure.
Galaxy S26 launch date confirmed
Samsung has officially confirmed that the Galaxy S26 series will launch on February 25, so we won’t have to wait long to see how these leaks hold up.
If these promotional materials are accurate, the Galaxy S26 Ultra looks like a refinement year rather than a dramatic leap, especially in battery and charging.
For power users, the lack of battery growth may be the most notable takeaway.
