Recent updates surrounding the upcoming Samsung Galaxy S27 series highlight significant hardware divergence across the four planned models, driven by massive new battery integrations for the Pro and Ultra variants.

Fresh accessory casing designs shared by trusted tipster Ice Universe illustrate how Samsung intends to visually separate its higher-end devices from the standard editions. Meanwhile, independent industry reports indicate that these premium handsets are the primary factor behind Samsung's delayed official launch schedule.

Galaxy S27 Cases Reveal Two Very Different Designs

Protective shells designed for the S27 and S27+ feature a familiar tall, rounded corner cutout tailored for a vertical camera column, mirroring the layout seen on the current Galaxy S26. In contrast, cases destined for the Pro and Ultra editions replace this setup with an expansive horizontal window stretching across the entire back panel.

The leaked imagery also underscores the remarkably compact form factor of the Pro model. Its housing measures noticeably shorter than the S27+, accommodating a 6.47-inch display as outlined by ET News, compared to the 6.66-inch screen on the Plus. At 6.89 inches, the Ultra remains the largest device in the quartet.

What Paying More For A Galaxy S27 Gets You

The sprawling camera bar serves a functional engineering purpose beyond aesthetics. Shifting the camera sensors away from the central chassis creates interior room for integrated Qi2 magnets, enabling magnetic accessories and battery packs to snap directly onto the phone without requiring a case. This capability is expected to remain exclusive to the Pro and Ultra.

Furthermore, the Pro and Ultra tiers are heavily tipped to incorporate Samsung Display’s advanced M16 OLED panels, whereas the more affordable sibling models will likely utilize the older M14 material. Galaxy Club previously indicated that the Pro and Ultra will leverage silicon-carbon batteries with approximate capacities of 5,200mAh and 5,700mAh, though integration plans for the base and Plus units remain unconfirmed.

Given that Samsung’s current foldable generation—including the cost-effective Galaxy Z Flip 8—relies entirely on silicon-carbon technology, it is plausible the entry-level S27 devices will adopt the same power cells.

Galaxy S27 Release Date: The Pro And Ultra Are Holding Things Up

According to insights shared by Korean insider Lanzuk on Naver, development on the S27 and S27+ is essentially finalized. Conversely, the Pro and Ultra models remain in flux as executives debate the final bill of materials. The primary deliberation involves transitioning to faster UFS 5.0 storage, alongside cost considerations surrounding cutting-edge LPDDR6 memory. Despite these internal discussions, Lanzuk maintains expectations for a reveal no later than February, with a January debut still possible.

Lanzuk cautions that the Pro and Ultra are already slated for high price points that could climb even further. Following Samsung's decision to raise the U.S. base price of the Galaxy S26 Ultra to $1,399.99 on October 1st, an even higher price tag for the S27 Ultra is entirely plausible.

Samsung may rely on advanced battery engineering, next-generation display tech, and overhauled styling within the Galaxy S27 Pro and Ultra to justify increased consumer costs, echoing the strategy used for the privacy screen on the Galaxy S26 Ultra. For mainstream buyers, the baseline S27 and S27 Plus will serve as accessible gateways into the 2027 flagship ecosystem.

Update October 23rd: Galaxy S27 Pro and Ultra Batteries Pictured For The First Time

First visual evidence of the power cells slated for Samsung's premier Galaxy S27 models has officially surfaced. Both components successfully cleared compliance checks with Safety Korea, the nation's primary regulatory body, complete with published photographs of each cell as highlighted by Notebookcheck.

Carrying model numbers EB-BS958DBY and EB-BS957CBY, the units correspond to the S27 Ultra and S27 Pro respectively, manufactured by China's Zhuhai CosMX Power. While exact ratings are obscured in the documentation imagery, prior leaks cited by Galaxy Club peg the rated metrics at 5,534mAh for the Ultra and 5,087mAh for the Pro. This points toward advertised commercial capacities near 5,700mAh and 5,200mAh—marking the first instance an Ultra-tier Galaxy smartphone has surpassed the 5,000mAh threshold. Charging speeds are projected to hold steady at 60W.

Notebookcheck emphasizes that these items represent pre-production hardware, leaving room for minor adjustments before mass manufacturing begins. Even so, while executive teams continue evaluating memory and storage configurations for the top-tier devices, the power architecture appears locked in. Securing safety approvals at this juncture aligns neatly with a projected Q1 launch window for the broader Galaxy S27 family.
