Samsung is expanding its upcoming Galaxy S27 smartphone family to include a new Pro variant alongside the standard, Plus, and Ultra models. Leaked specifications suggest the high-end Ultra version will undergo a significant design overhaul to integrate native magnetic charging and a high-density battery.
The Addition of the Galaxy S27 Pro to the Four-Device Lineup
According to the report, Samsung plans to shift from a three-tier to a four-tier product strategy next year. The lineup will consist of the Galaxy S27, S27 Plus,S27 Pro, and S27 Ultra. This expansion allows Samsung to create a more nuanced price and feature gap between the affordable base model and the premium Ultra.
Industry insider Ice Universe has provided drawings comparing the Galaxy S26 Ultra and the Galaxy S27 Ultra, noting that while the front profiles remain similar with slightly more curved edges on the newer model, the rear designs differ wildly. The base Galaxy S27 is expected to remain nearly identical in size to its predecessor, measuring 149.75 x 71.88 x 7.25mm, suggesting that the most aggressive innovation is reserved for the hihger-end Pro and Ultra tiers.
A 5,700mAh Leap via Silicon-Carbon Technology
The most significant internal upgrade is the transition to silicon-carbon battery technology, which allows for higher energy density without increasing the physical footprint of the device. As reported by the source, the Galaxy S27 Ultra is expected to feature a battery approaching 5,700mAh, a substantial jump from the 5,000mAh capacity found in the Galaxy S26 Ultra. The Galaxy S27 Pro is rumored to utilize the same technology with a capacity of approximately 5,200mAh.
This move follows a successful test run with the Galaxy Z Fold 8, which debuted silicon-carbon cells in July to fit a 4,800mAh battery into a slimmer chassis. By migrating this technology to the mainstream S-series, Samsung is positioning itself to outperform the iPhone 18, which is not expected to adopt silicon-carbon batteries in its primary flagship lineup this year.
How the Horizontal Camera Bar Enables Native Qi2 Magnets
To implement built-in Qi2 magnetic charging—similar to Apple's MagSafe—Samsung must move its camera hardware. The Galaxy S27 Ultra will reportedly replace its traditional vertical camera column with a large rectangular horizontal camera island. This design shift clears the center of the back panel, allowing for the installation of native magnets that enable accessories to snap directly to the phone without a case.
This architectural change validates a prediction made in April by insider Lanzuk, who suggested a camera redesign was imminent. While the Galaxy S26 relied on official cases to provide magnetic functonality for its Qi2 battery packs, the Galaxy S27 Ultra appears to be the first flagship to integrate this hardware natively into the chassis.
Which Specific Sensors Will Fill the S27 Ultra's New Camera Island?
Despite the detailed leaks regarding dimensions and battery capacity, several critical questions remain. The source describes a "large rectangular camera island" for the Galaxy S27 Ultra, but it does not specify if this redesign accompanies new sensor hardware or simply a new arrangement of existing lenses. Furthermore, it remains unclear if the native Qi2 magnets will be extended to the Galaxy S27 Pro and S27 Plus, or if they will remain exclusive to the Ultra.
There is also a lack of clarity regarding the software integration for these magnets. While the hardware allows for accessories to attach,it is unknown if Samsung will introduce new software-level features to manage the power delivery and heat dissipation associated with the 5,700mAh silicon-carbon battery during high-speed magnetic charging.
