Samsung Galaxy S27 Ultra to Surpass Longstanding 5,000 mAh Barrier
The forthcoming Samsung Galaxy S27 Ultra may finally transcend the longstanding 5,000 mAh limitation that the company has adhered to for years.
Recent government documents indicate a noteworthy battery capacity of 5,534 mAh, which could be marketed as a 5,700 mAh unit.
Additionally, sources suggest that the Galaxy S27 Pro is poised to feature a battery rated at 5,087 mAh, with a potential marketing figure of approximately 5,200 mAh. Reports also indicate that both flagship devices will incorporate support for 60W wired charging.
The Galaxy S27 Ultra’s Battery: Anticipating 5,700 mAh
Information from China’s 3C certification records and other battery listings suggests that the Galaxy S27 Ultra, bearing the model number SM-S958, is equipped with a battery rated at 5,534 mAh.
If accurate, this could imply an effective capacity close to 5,700 mAh. As of yet, Samsung has not officially verified this particular number.
In contrast, the current Galaxy S26 Ultra is outfitted with an advertised 5,000 mAh battery.
Should these leaked figures hold true, it would signify an enhancement of approximately 700 mAh, equating to a 14% increase.
The Galaxy S27 Pro: A Leap to a 5,200 mAh Battery
Furthermore, the Galaxy S27 Pro appears set for a substantial upgrade as well. Tentatively linked to the model number SM-S957, this device could feature a nominal battery capacity of 5,087 mAh, which is expected to be marketed as around 5,200 mAh.
This improvement becomes particularly striking if the Pro model maintains its relatively compact dimensions.
At this juncture, Samsung has not formally acknowledged either the Galaxy S27 Pro’s existence or its battery specifications.
Both Models Expected to Support 60W Charging
The same 3C certification records indicate that both the Galaxy S27 Pro and the Galaxy S27 Ultra will support 60W wired charging.
Consequently, the Ultra model will maintain the 60W charging capability first introduced with the Galaxy S26 Ultra, without any further enhancements.
Interestingly, for the Pro variant, this 60W charging capability denotes a new development based on current leaks.
Nonetheless, the certification does not elucidate the actual charging speeds consumers can expect during everyday use; charging performance, including rates and sustainability, will only be discerned through empirical testing.
Is Samsung Transitioning to Silicon-Carbon Technology?
This matter introduces a fascinating dimension to the story. Samsung is reportedly exploring silicon-carbon battery technology for the Galaxy S27 series, following indications of this technology being utilized in its latest lineup of foldable devices.
Silicon-carbon cells hold the potential for superior energy densities compared to traditional lithium-ion batteries.
This innovation allows manufacturers to augment power without significantly increasing device thickness.
However, the 3C certification does not confirm the chemical composition of the batteries, which means associations between the S27 series and silicon-carbon technology remain speculative until ratified by Samsung.
Is 5,700 mAh Sufficient?
This raises a pivotal question for Samsung. A 5,700 mAh battery would indeed represent a significant advancement over the 5,000 mAh cells used in the Galaxy S26 Ultra; yet, many Android competitors are now eclipsing the 6,000 mAh threshold.
There have even been speculations that Samsung trialed a Galaxy S27 Ultra prototype featuring a staggering 7,000 mAh capacity, although this configuration may not be reflected in the final model.
Moreover, certain flagship devices from rival companies are expected to sport batteries approaching or exceeding the 7,000 mAh mark.
Thus, while a 5,700 mAh battery signifies a notable increase for the Galaxy S Ultra line, mere enhancements in battery size do not guarantee prolonged longevity.
Several factors, including screen efficiency, processor power consumption, software optimization, and camera usage frequency, will dictate overall battery life.
For the moment, leaked figures suggest that Samsung is indeed progressing beyond the 5,000 mAh threshold.

Yet, until the official launch of the Galaxy S27 Ultra and comprehensive lab testing, the true adequacy of this additional capacity in closing the performance gap with its Chinese Android competitors remains unverified.
