Samsung's Galaxy S27 Ultra is expected to launch in early 2027 with several major hardware changes, including a 5,700mAh silicon-carbon battery that ends a seven-generation run at 5,000mAh on the Ultra line, built-in Qi2 magnetic charging magnets, and a possible self-healing Gorilla Armor coating developed with Corning. Wired charging is expected to stay at 60W, unchanged from the Galaxy S26 Ultra. The device is rumored to use Qualcomm's Snapdragon 8 Elite Extreme Gen 6 chip, enabling 8K video at 60fps and 4K slow-motion at 240fps. Samsung is also expanding the lineup to four models with a new Galaxy S27 Pro positioned between the Plus and Ultra. The series is expected to debut One UI 9.5 with advanced AI features based on Google's Gemini 4.0. Pricing is likely to stay in the mid-2 million won range at the top end, undercutting Apple's iPhone 18 Pro Max.
Samsung Electronics is preparing one of its most substantial flagship overhauls in years with the Galaxy S27 Ultra, as a wave of early leaks points to a larger silicon-carbon battery, a potential self-healing display coating, built-in magnetic charging magnets, and a new high-performance chip from Qualcomm that could double the frame rate of 8K video recording. The device, expected to be unveiled in early 2027, is shaping up as Samsung's answer to Apple's recently launched iPhone 18 Pro lineup. While the South Korean company has not confirmed any specifications, regulatory filings and supply-chain reports are beginning to fill in a picture of a phone that breaks from several long-standing hardware traditions. Battery and Charging: Breaking the 5,000mAh Ceiling The most concrete change may be in the battery. Samsung has kept its Ultra models at a 5,000mAh capacity for multiple generations, but recent 3C certification filings suggest the Galaxy S27 Ultra will jump to a 5,700mAh typical capacity, with a rated figure of roughly 5,534mAh. The increase is made possible by a shift to silicon-carbon battery technology, which offers higher energy density than conventional lithium-ion cells and allows manufacturers to pack more capacity into a similar physical footprint. That would end one of the longest runs of stagnation in the premium segment. Samsung has shipped a 5,000mAh cell in every Ultra model since the Galaxy S20 Ultra in 2020, through seven consecutive generations.
Wired charging, by contrast, is not expected to move. The same 3C listings rate the Galaxy S27 Ultra at 60W, matching the Galaxy S26 Ultra, which raised the Ultra line from its long-standing 45W ceiling when it launched in February. The Galaxy S27 and S27 Plus were certified separately at 25W and 45W, leaving the faster tier to the Pro and Ultra. The device is additionally rumored to support native magnetic Qi2 alignment, which would bring the Galaxy ecosystem closer to the magnetic accessory experience Apple popularized with MagSafe. That would be a first for the Ultra. Samsung shipped the Galaxy S26 series without magnets inside the chassis, a decision the company defended at launch, so magnetic chargers and mounts have required a magnet-equipped case until now. A Self-Healing Display Coating Perhaps the most unusual rumor circulating is that Samsung and Corning are jointly developing a self-healing version of Gorilla Armor for the next-generation flagship. Unlike conventional scratch-resistant glass, the reported coating would allow the surface to recover from minor micro-scratches accumulated through everyday use, such as contact with sand or grit trapped in a pocket. The technology would not repair a shattered display or remove deep gouges. Instead, it appears aimed at the fine surface marks that gradually accumulate on even highly scratch-resistant glass. Neither Samsung nor Corning has confirmed the development, and the mechanism remains unknown. Self-healing materials typically rely on polymers or other compounds that return toward their original structure after minor damage, sometimes with the help of heat or simply over time. It is also unclear where Samsung might apply the coating. The original report refers generally to a new generation of Gorilla Armor, meaning it could appear on the front display, the rear panel, or both. The Galaxy S26 Ultra uses Gorilla Armor 2 on its front glass. LG experimented with a similar concept more than a decade ago on the G Flex series, but bringing a substantially more advanced version to the front of a modern flagship would represent a far more significant step. A New Chip and a Big Video Leap Performance upgrades are expected to center on Qualcomm's Snapdragon 8 Elite Gen 6 family, which the chipmaker unveiled on Sept. 22. The standard Snapdragon 8 Elite Gen 6 delivers a 10% CPU improvement, a 35% GPU gain, and a 14% NPU boost over its predecessor, along with roughly 40% better power efficiency. For the Ultra and a new Pro model, Samsung is widely expected to use the higher-tier Snapdragon 8 Elite Extreme Gen 6. Both chips are built on TSMC's 2nm process and are the first smartphone processors to run at 5GHz. Qualcomm rates the Extreme variant's CPU 13% faster than the previous generation and its GPU 44% faster, against 10% and 35% for the standard part. That Extreme variant could unlock a significant leap in mobile videography. The chip supports 8K video recording at 60 frames per second, double the 30fps ceiling of the current Galaxy S26 Ultra, as well as 4K slow-motion at 240fps. Qualcomm's upgraded Spectra image signal processor and Advanced Pixel Video codec are designed to handle the enormous data loads these formats generate. Samsung will need to solve several engineering challenges to make those features reliable, including thermal management for sustained 8K recording, storage efficiency for very large files, and battery optimization under heavy processing loads. Software integration, including real-time subject tracking and noise reduction, will also determine how well the hardware performs in practice. Samsung's own Exynos 2700 processor is also in the mix. Early benchmark scores indicate a substantial performance improvement over previous Exynos chips, and industry watchers expect the base Galaxy S27 to use either Snapdragon or Exynos depending on region, as in prior generations. Some reports even raise the possibility that the Ultra could use Exynos in certain markets for the first time.
