Samsung Galaxy S27 Pro Rumors Point to Ultra Features in a Smaller Phone

A fourth Galaxy S27 could change the choice for buyers

Samsung is reportedly preparing a Galaxy S27 Pro with a 6.47-inch display, potentially giving buyers many of the Ultra model's features without its larger screen or S Pen. The proposed phone would join the Galaxy S27, S27 Plus and S27 Ultra in a lineup expected in early 2027.

Production plans reportedly shared with suppliers include four flagship projects, identified as ON1 through ON4, with initial assembly scheduled for December 2026 and continuing into January 2027 and beyond. Samsung Display is also reportedly producing OLED panels for the phones.

The Pro would introduce a different choice within Samsung's flagship range: a smaller premium phone rather than another model defined mainly by its screen size. Rumored specifications include cameras shared with the Ultra, Privacy Display technology and a battery with an estimated typical capacity of about 5,200 mAh.

Samsung has not announced the four models, their specifications, prices or release dates. The emerging picture combines supplier planning, reported battery certifications and claims from people who publish information about unreleased devices. Several details remain unsettled, particularly processors, memory and the exact launch schedule.

For buyers, the central change would be straightforward. Someone seeking Samsung's most advanced cameras and display features might gain an alternative to the largest Galaxy S phone. For Samsung, adding a second expensive model could help bring in more revenue per handset as memory and other components become more costly.

Where the Pro would fit

The reported screen sizes place the Pro between the standard S27 and the Plus, even though its expected features put it closer to the Ultra. The proposed lineup looks like this:

• Galaxy S27: a 6.27-inch display, the smallest of the four.
• Galaxy S27 Pro: a 6.47-inch OLED display, with many Ultra features but no S Pen.
• Galaxy S27 Plus: a display reported at 6.66 inches, with another account giving 6.6 inches.
• Galaxy S27 Ultra: a 6.89-inch display, retaining the largest format.

The Pro's reported screen diagonal is just 0.20 inches longer than the standard model's and 0.42 inches shorter than the Ultra's. Screen diagonals alone do not tell buyers how wide or heavy a phone will be, but these figures explain the intended position: premium hardware in a smaller format.

Samsung has built its main Galaxy S range around standard, Plus and Ultra models since the Galaxy S20 generation in 2020. It also tried a different fourth option with the Galaxy S25 Edge in 2025, focusing on a thin, lightweight design. Demand for that device was reportedly weak, and Samsung did not follow it with another Edge model in 2026.

The proposed Pro takes a different approach. Rather than making thinness the main attraction, it would offer buyers a smaller way to obtain features usually associated with the Ultra.

Ultra cameras, without the S Pen

The Galaxy S27 Pro and Ultra are rumored to share a rear camera system comprising a 200MP main camera, a 50MP ultrawide camera and a 50MP telephoto camera with 5x optical zoom.

An ultrawide camera fits more of a scene into the frame, while a telephoto camera brings distant subjects closer. Optical zoom uses the camera's lens system to achieve that closer view. Megapixel figures describe image resolution; the final photographs also depend on the sensor, lenses and image processing.

The Pro is also tipped to receive Samsung's Privacy Display technology. This feature is intended to make the screen harder to view from the side, helping keep nearby people from reading its contents. Its inclusion would make the Pro's display features another reason to choose it over the standard or Plus model.

The S Pen would remain a major dividing line. The Pro is expected to leave out Samsung's stylus, giving buyers who do not use pen input a smaller premium option. Battery capacity and display size would also separate it from the Ultra.

Processor claims are less consistent. One expectation is that the Pro would share the Ultra's next generation Snapdragon chip. Another suggests the Pro could use either Exynos 2700 or Snapdragon 8 Elite Extreme Gen 6 depending on the market, while the Ultra would use Qualcomm chips exclusively. Under that second account, most standard and Plus models outside China and North America would use Exynos 2700.

Battery listings provide more specific clues

Reported Safety Korea certification listings identify batteries associated with the S27 Ultra and Pro as EB-BS958DBY and EB-BS957CBY, respectively. Their certification numbers are YU10899-26034 and YU10899-26036. Both batteries are reportedly manufactured by Zhuhai CosMX Power Jinwan Subsidiary in China.

The capacities in the accompanying photographs are difficult to read. Reported Chinese 3C certification details give rated capacities of 5,534 mAh for the Ultra and 5,087 mAh for the Pro. Estimated typical capacities are about 5,700 mAh and 5,200 mAh.

Rated capacity is a specified battery value, while typical capacity describes the representative value commonly used in marketing. Keeping those categories separate matters when comparing the two devices.

Using the estimated typical figures, the Ultra would have 500 mAh more capacity than the Pro. Its proposed 5,700 mAh battery would also be 700 mAh, or 14%, larger than the 5,000 mAh battery attributed to the Galaxy S26 Ultra. Actual time between charges would depend on the screen, processor, software and how the phone is used.

The reported 3C filing lists 60 W wired charging for both models, matching the S26 Ultra's reported charging specification. The certified batteries are samples made before commercial production, so retail versions may change. Separate rumors describe the new batteries as using silicon and carbon, a technology intended to fit more capacity into a given space.

A familiar front and a different back

Leaked screen protector images cover the S27, S27 Plus and S27 Ultra, showing rounded corners and centered openings for their front cameras. The Ultra appears to retain the softer corner shape associated with the Galaxy S26 Ultra. The Pro is absent from those images.

Claims about the Ultra's screen borders are less settled. Some descriptions suggest slightly slimmer bezels than the S26 Ultra, while another assessment says the protector images leave bezel thickness unclear. Accessory makers can work from preliminary dimensions, leaving the final front design uncertain.

Images of alleged cases shared by tipster Ice Universe suggest a more visible change at the back. The standard and Plus cases have tall camera openings near an upper corner, while the Pro and Ultra cases have wide horizontal openings across the upper rear.

The premium pair could also receive built-in Qi2 magnets. These would let compatible magnetic accessories and battery packs attach directly to the phones, without requiring a case that supplies the magnets. Rumors connect the horizontal camera arrangement with making room for that hardware.

The Pro and Ultra are tipped to use Samsung Display's M16 OLED materials, while the standard and Plus could use M14 materials. Those names refer to generations of materials used in the display. Brightness, efficiency and other differences would need to be assessed from the finished panels.

Memory choices could affect both speed and price

Tipster @kro_roe has described possible configurations that Samsung is reportedly still evaluating as component costs rise. The standard S27 and Plus could offer 8GB or 12GB of RAM and 256GB or 512GB of storage. The Pro is tipped to have 12GB of RAM with either 256GB or 512GB of storage.

The Ultra could offer 12GB of RAM with 256GB or 512GB of storage, plus a version with 16GB of RAM and 1TB of storage. A configuration combining 16GB and 1TB has also been mentioned for the Pro, although the same set of claims expects 1TB to remain exclusive to the Ultra. The Pro's highest capacity option is therefore unresolved.

RAM is the phone's working memory, used by running apps. Storage holds photographs, videos, downloaded files and installed apps. A phone can have more of one without having more of the other.

Samsung is reportedly considering LPDDR6 RAM and UFS 5.0 storage for the premium models. These are generations of memory and storage technology that could affect performance, power use and manufacturing costs. Different UFS versions may be used across the range.

Samsung may also reuse components left over from Galaxy S26 production, according to the initial claims. No particular parts or quantities have been identified, leaving their possible effect on the new phones unclear.

Why a more expensive Pro could appeal to Samsung

Rising memory prices create pressure on the business selling the finished phone. Samsung's semiconductor operations may benefit from higher chip prices, while its mobile operations face higher costs when obtaining those components.

The production planning account puts the combined operating loss for Samsung's Mobile eXperience and Networks businesses at about 700 billion won in the second quarter of 2026. It also cites securities market estimates of a loss around 1 trillion won in the third quarter. The third quarter figure is an estimate, and these amounts concern the combined businesses rather than the Galaxy S range alone.

A Pro could help Samsung raise its average selling price, meaning the average amount earned from each phone sold. A standard or Plus buyer moving to a more expensive Pro would increase that figure. An Ultra buyer choosing a cheaper Pro would have the opposite effect on the amount received from that purchase.

That makes the differences between models commercially important. Samsung would need to make the Pro attractive enough to encourage buyers to spend more, while preserving reasons to choose the Ultra, including its larger screen and S Pen.

Price increases are also being discussed. The Galaxy S26 Ultra's US price reportedly rose to $1,399.99 on October 1, 2026. No S27 price has been announced, so buyers do not yet have a firm figure for either the proposed Pro or its larger sibling.

January is possible, but the schedule is unsettled

Reported supplier plans point to December assembly, while launch predictions range from early January to February 2027. Tipster Lanzuk has suggested an early January launch, potentially several weeks ahead of the S26 generation's schedule.

Accounts of hardware readiness differ. One says Samsung has finalized all major components. Others say the standard and Plus are largely complete, while memory and storage decisions remain pending for the Pro and Ultra. The reported sequence is:

• 2025: Samsung introduced the Galaxy S25 Edge, whose demand was reportedly weak.
• February 25, 2026: Samsung announced the Galaxy S26 series, according to the launch chronology cited in the reports.
• March 6, 2026: The S26 series went on sale.
• October 20, 2026: A report described leaked S27 screen protector images covering three models.
• December 2026: Initial assembly of four reported flagship projects is scheduled to begin.
• January or February 2027: The expected S27 introduction window, with early January among the predictions.

An early January introduction would bring the announcement forward from the S26's late February event. The exact interval between announcement and retail availability has not been given.

Launch benefits may change alongside the phones

The Galaxy S27 range is reportedly expected to arrive with One UI 9.5, Samsung's phone software interface. Buyers may also see familiar purchase incentives, including discounts on Galaxy Buds and Galaxy Watch devices, charger coupons and Google service subscriptions lasting six to 12 months.

Free storage upgrades could become less generous. If Samsung reduces those promotions, a buyer seeking 512GB might have to pay more even if the advertised starting price changes little. The practical cost comparison will depend on the storage capacity and benefits included with each offer.

Samsung's smart glasses are separately expected to become available in November, with software controlled by Google. Details about their price and their connection to the proposed S27 range have not been given.

The S27 rumors point toward a range split by features as well as size: standard and Plus models as the less expensive choices, and Pro and Ultra models carrying more advanced cameras, displays and accessory support. The proposed Pro is the key addition because it could make those premium features available in a phone smaller than either the Plus or Ultra.
