The highly anticipated Samsung Galaxy S26 Ultra is expected to launch globally, including in India, in January 2026. Over the past few months, several leaks have surfaced online regarding its specifications and features. One of the most discussed aspects has been its battery capacity. While earlier reports suggested that Samsung might increase the size of the battery, a recent certification listing indicates otherwise.
Samsung Galaxy S26 Ultra Battery Capacity Leaks
According to a listing spotted on the China Quality Certification Centre (CQCC) website, the Samsung Galaxy S26 Ultra battery capacity will reportedly remain at 5,000mAh, the same as its predecessor, the Galaxy S25 Ultra. This contradicts earlier claims that Samsung might equip the device with a 5,500mAh battery.
This is not the first time the battery details have leaked online, but the CQCC listing adds more weight to the possibility that Samsung is sticking to the same capacity.
No Major Battery Upgrade Since Galaxy S20 Ultra
Interestingly, since the launch of the Galaxy S20 Ultra, Samsung has not increased the battery capacity of its flagship “Ultra” lineup. Instead, the company has been focusing on software improvements and energy-efficient processors to provide solid battery performance. The Samsung Galaxy S25 Ultra, for example, offered good endurance despite carrying the same 5,000mAh battery.
Expected Charging and Performance Upgrades
While the Samsung Galaxy S26 Ultra battery capacity may not see a boost, charging speed might get a big upgrade. Reports suggest that the device could support 60W or even 65W wired fast charging, compared to the Galaxy S25 Ultra’s 45W charging. Wireless charging may also remain at 25W.
In addition, the smartphone is rumored to be powered by the upcoming Snapdragon 8 Elite 2 chipset, paired with up to 16GB of RAM, ensuring smooth performance for demanding users.
Other Expected Features of Samsung Galaxy S26 Ultra
- A 6.9-inch AMOLED display with high refresh rate
- IP68 rating for dust and water resistance
- A powerful camera setup including:
- 200MP ISOCELL HP2 primary sensor
- 50MP ultra-wide-angle lens
- 12MP telephoto sensor
- 50MP periscope lens
Final Thoughts
Although the Samsung Galaxy S26 Ultra battery capacity might stay the same at 5,000mAh, the improvements in charging speed and chipset efficiency could still deliver a better overall experience. Fans of the Galaxy Ultra lineup can look forward to more details as the official launch date in January 2026 gets closer.
