Samsung Galaxy S27 Ultra Leak: 5,700mAh Battery and 60W Charging Tipped

The Samsung Galaxy S27 Ultra leak has started attracting attention after tipster Gadgetsdata shared a concept render and claims about the upcoming flagship’s design on X. At the same time, a reported 3C certification listing has revealed battery and charging details for the Galaxy S27 Ultra and Galaxy S27 Pro. However, all these details are still at the leak stage, and Samsung has announced nothing about the Galaxy S27 series.

According to the reported certification information, the Galaxy S27 Ultra could feature a 5,534mAh rated battery, which would likely be advertised as around 5,700mAh typical capacity. The listing also points to 60W wired charging. If these details turn out to be accurate, the battery capacity would be higher than the 5,000mAh battery used in the Galaxy S26 Ultra, while the charging speed would remain unchanged.

Samsung Galaxy S27 Ultra Leak Points to a Bigger Battery

The biggest detail from the reported listing is the battery capacity. The Galaxy S27 Ultra is said to have a 5,534mAh rated battery. In smartphone specifications, the rated capacity can be lower than the typical capacity used in marketing, so this figure is expected to translate to around 5,700mAh when advertised.

For comparison, the Galaxy S26 Ultra has a 5,000mAh battery. That means the leaked Galaxy S27 Ultra figure would represent a noticeable increase in battery capacity if it eventually reaches the final commercial device.

This would also put Samsung’s next Ultra flagship closer to the direction already being followed by several Android rivals, which are increasingly launching smartphones with batteries above 6,000mAh. However, battery capacity alone does not determine real-world battery life, so it would be too early to draw conclusions about how long the Galaxy S27 Ultra could actually last.

Galaxy S27 Ultra Could Retain 60W Charging

The same reported 3C certification listing points to 60W wired charging for the Galaxy S27 Ultra. Interestingly, this is the same charging speed listed for the Galaxy S26 Ultra, meaning the leaked information does not suggest a charging-speed increase for Samsung’s next Ultra model.

If the certification information is accurate, Samsung could be increasing the battery capacity without increasing the wired charging rating. A larger battery combined with the same 60W charging speed would make charging performance an important area to watch when more reliable information becomes available.

For context, MobileTelco has previously covered the Galaxy S26 series and its early reports. The current Galaxy S27 Ultra information should be treated separately because the S27 series has not been officially announced by Samsung.

Galaxy S27 Pro Battery and Charging Details Also Leaked

The reported certification information also mentions the Galaxy S27 Pro. This model is listed with a 5,087mAh rated battery, which would work out to around 5,200mAh typical capacity when advertised. The Galaxy S27 Pro is also listed with 60W charging.

These figures suggest that the reported battery increase may not be limited to the Ultra model. However, the Galaxy S27 Pro details are also unconfirmed, and Samsung has not announced the model or provided official specifications.

What the Galaxy S27 Ultra Design Leak Says

Alongside the battery-related information, tipster Gadgetsdata has shared a concept render of the Galaxy S27 Ultra and claims about its design. The render is not an official Samsung image, and the design information should therefore be viewed as an early indication rather than a confirmed look at the final phone.

At this stage, there are no confirmed design specifications from Samsung for the Galaxy S27 Ultra. The concept render can give readers an idea of what the reported design direction may look like, but Samsung could change the design before the phone is officially announced.

How the Leaked Galaxy S27 Ultra Battery Compares

Model	Reported/Rated Battery	Expected Typical Capacity	Wired Charging
Galaxy S26 Ultra	5,000mAh	5,000mAh	60W
Galaxy S27 Ultra	5,534mAh	Around 5,700mAh	60W
Galaxy S27 Pro	5,087mAh	Around 5,200mAh	60W

The table shows the main battery and charging figures currently associated with the leaked models. The Galaxy S27 Ultra’s reported rated capacity is higher than the Galaxy S26 Ultra’s 5,000mAh battery, while the reported charging speed remains at 60W.

Samsung Galaxy S27 Ultra Leak: What Is Confirmed So Far?

Nothing has been officially confirmed by Samsung at this stage. The Galaxy S27 Ultra design information comes from a tipster’s concept render and claims, while the battery and charging information is based on a reported 3C certification listing.

• Gadgetsdata has shared a Galaxy S27 Ultra concept render and design claims.
• The reported 3C listing shows a 5,534mAh rated battery for the Galaxy S27 Ultra.
• The Ultra model is reportedly listed with 60W wired charging.
• The Galaxy S27 Pro is reportedly listed with a 5,087mAh rated battery and 60W charging.
• Samsung has not announced the Galaxy S27 Ultra or officially confirmed these specifications.

Conclusion

The Samsung Galaxy S27 Ultra leak currently points to a larger 5,534mAh rated battery, around 5,700mAh typical capacity and 60W wired charging. The Galaxy S27 Pro is also reportedly listed with a 5,087mAh rated battery and 60W charging. The reported Ultra battery would be larger than the Galaxy S26 Ultra’s 5,000mAh battery, while the charging speed would remain the same.

For now, these details should remain firmly in the leak category. Gadgetsdata’s concept render and claims, along with the reported 3C certification information, do not represent an official Samsung announcement. More reliable information will be needed before the Galaxy S27 Ultra’s final design, battery capacity or charging specifications can be treated as confirmed.
