Samsung is already teasing the upcoming Galaxy S26 Ultra, which won’t launch until 2026, but some details have surfaced that have caught the attention of enthusiasts. While Samsung’s S25 Ultra model debuted with a 5,000 mAh battery, it seems the Galaxy S26 Ultra will stick to the same capacity. However, there’s a twist: the energy density is reportedly being increased, making the battery more efficient and smaller than its predecessor. 
Although the battery remains the same size, it may be able to store more power in a compact form.
The change in battery technology could also allow for faster charging, though exact details are still under wraps. The S25 Ultra supported a charging speed of up to 45W, so it’s possible the S26 Ultra will see an improvement in this area too, but we’ll have to wait for more official information.
When it comes to the camera, the Galaxy S26 Ultra is expected to keep the same 200MP resolution as the previous model. The question remains, though: will it use a new sensor, or will Samsung rely on the existing one? This has yet to be confirmed. With Samsung’s reluctance to fully change its core hardware with each release, fans may be wondering if they’ll see any groundbreaking new features with the S26 Ultra, or if it will be a repeat of past designs.
Samsung’s Galaxy S26 series won’t be unveiled until January 2026, but as we get closer to that date, expect more rumors and leaks to surface. For now, these initial details suggest that while the battery might get more efficient, the camera may be a more familiar offering. Whether or not that’s enough to keep Samsung competitive in a rapidly evolving market remains to be seen.
