Samsung might finally be answering years of feedback from its most loyal Galaxy Ultra users. If the latest leaks are accurate, the upcoming Galaxy S26 Ultra 5G could see its first major power upgrade since the Ultra series debuted in 2020.
Alongside expected performance and camera improvements, the real highlight this time might just be a bigger battery and faster charging — something fans have long demanded.
Battery
Samsung has been playing it safe with battery capacity and charging speeds on its flagship Ultra devices for a while now. From the Galaxy S21 Ultra through to the S25 Ultra, we’ve seen the same 5000mAh battery paired with 45W fast charging — no major changes year after year.
That could change with the Galaxy S26 Ultra 5G. According to a trusted tipster on X (formerly Twitter), @chunvn8888, Samsung might finally give the Ultra a power bump with:
- 5500mAh battery
- 65W fast charging
If true, that’s a 10 percent boost in battery capacity and an impressive 45 percent increase in charging speed over the current model.
This would bring Samsung more in line with what competitors like Xiaomi and OnePlus have been offering in the premium segment.
| Galaxy Ultra Model | Battery | Charging Speed |
|---|---|---|
| Galaxy S21 Ultra | 5000mAh | 45W |
| Galaxy S22 Ultra | 5000mAh | 45W |
| Galaxy S23 Ultra | 5000mAh | 45W |
| Galaxy S25 Ultra | 5000mAh | 45W |
| Galaxy S26 Ultra (Leak) | 5500mAh | 65W |
Camera
The S26 Ultra is also rumored to receive some camera hardware upgrades. While the 200MP primary sensor is expected to stay, it might come with a new Sony 1/1.1-inch sensor, which could significantly boost image quality and low-light performance.
Other expected camera improvements include:
- Telephoto lens upgrade from 10MP to 12MP
- Enhanced zoom clarity
- Better image processing with AI features
Samsung might continue refining its photography game, which has become a strong selling point for its Ultra models in recent years.
Performance
On the performance front, the Galaxy S26 Ultra is expected to be powered by the Snapdragon 8 Gen 2 Elite chipset — a newer, more efficient variant that will likely bring better thermal performance and battery efficiency.
Key expected specs:
- Snapdragon 8 Gen 2 Elite
- Up to 16GB RAM
- UFS 4.0 storage for faster read/write speeds
These upgrades should ensure a smoother multitasking and gaming experience.
Design
Some leaks also hint at design changes. The Galaxy S26 Ultra 5G could be:
- Slimmer and lighter than the previous Ultra models
- Possibly using a new material blend to reduce weight
- Minor tweaks to the frame and camera layout
While design hasn’t drastically changed in recent Ultra models, Samsung might be taking steps to improve the feel in hand without sacrificing battery size.
Final Word
If these leaks are to be believed, the Galaxy S26 Ultra 5G may finally bring meaningful upgrades to the battery and charging — two areas that have seen little progress over the years.
Add in solid camera and performance enhancements, and Samsung could be setting up a strong flagship for 2025.
However, as with all pre-launch leaks, it’s best to take the information with a pinch of salt. The S26 Ultra is still months away from an official reveal, and Samsung has yet to confirm any of these changes.
