Samsung Galaxy S27 Ultra: Everything You Need to Know in December 2025
The Samsung Galaxy S27 Ultra arrived with a bang in early 2025, immediately positioning itself as one of the most talked‑about flagships of the year. Five months after its launch, the device has weathered real‑world use, earned a raft of reviews, and even seen a few price adjustments. Whether you’re considering a upgrade from a S26 Ultra or simply curious about Samsung’s latest powerhouse, this guide breaks down the phone’s release timeline, design, hardware, camera, battery, pricing, and how it stacks up against its predecessor—all as of December 2025.
When Did the Samsung Galaxy S27 Ultra Launch?
Samsung’s Galaxy Unpacked event on February 12, 2025, unveiled the S27 Ultra, with pre‑orders opening the same day and worldwide availability beginning February 28, 2025. By December 2025 the phone is no longer a “new release” but a mature product that has received several software updates and minor price tweaks. carriers such as Verizon, AT&T, and T‑Mobile have kept the device in their portfolios, while Samsung’s own online store continues to offer direct purchases.
Design and Display
Exterior Build and Materials
The S27 Ultra keeps the familiar “infinity‑display” front with a centered punch‑hole selfie camera, but Samsung refined the chassis this generation. The phone measures 163.8 mm × 78.3 mm × 7.9 mm (excluding the camera module) and weighs 228 g, making it slightly slimmer than the S26 Ultra despite the larger screen. A premium aluminum frame and Gorilla Glass Victus 2 on both front and back give it a sturdy feel, while the camera bump is now more integrated, featuring a subtle matte finish that reduces glare.
Display Specifications
The star of the show is a 6.9‑inch Dynamic AMOLED 2X panel with a 3200 × 1440 resolution, 120 Hz adaptive refresh rate, and peak brightness of 2000 nits (HDR). Samsung introduced a new “Eye‑Comfort” mode in the December 2025 software update, which reduces blue light without sacrificing color accuracy. The display has received praise for its vivid colors, deep blacks, and smooth scrolling, making it a benchmark for media consumption and gaming.
Key Hardware Specs
Under the hood, the S27 Ultra is powered by Qualcomm’s Snapdragon 8 Gen 3 (SM8450) processor, built on a 4 nm process, paired with 12 GB of LPDDR5X RAM. Samsung also offers an Exynos 2700 variant for select markets, though the Snapdragon version dominates global sales. Storage options remain unchanged from the S26 Ultra: 256 GB, 512 GB, and a 1 TB model, all using UFS 4.0. The phone supports 5G Sub‑6 and mmWave, Wi‑Fi 7, Bluetooth 5.3, and includes an NFC chip for mobile payments.
Camera System
The S27 Ultra features a refined triple‑camera setup that drops the previous quadruple arrangement for a more streamlined look. The system includes:
- 200 MP (1/1.3″) ISOCELL HP1 main sensor with OIS and 8K video capture.
- 50 MP (1/2.5″) telephoto lens with 3× optical zoom, OIS, and Leica‑branded processing.
- 50 MP (1/2.5″) ultrawide lens with 123° field of view and autofocus for macro shots.
- 12 MP (1/3.24″) selfie camera with autofocus and Dual Pixel technology.
Samsung’s “ProVisual 2.0” software, updated in the October 2025 patch, adds AI‑driven scene optimization, improved night photography, and a new “Lens‑Blend” mode for seamless portrait backgrounds. Early reviews from TechRadar and The Verge highlighted the ultra‑sharp main sensor and the natural-looking zoom quality, calling the system “the best overall camera package in its class.”
“The S27 Ultra’s camera delivers stunning detail in daylight and handles low‑light scenarios far better than its predecessor, thanks to larger pixel sizes and smarter AI processing.” – TechRadar, December 2025
Battery Life and Charging
A 5,700 mAh battery powers the S27 Ultra, a modest increase over the S26 Ultra’s 5,500 mAh cell. In real‑world testing, the device easily survived a full day of mixed usage—web browsing, streaming, gaming, and photography—returning 12‑13 hours of screen‑on time. The December 2025 firmware tweak introduced a more aggressive power‑management algorithm, extending typical battery life by roughly 10 %.
Charging remains fast: 60 W wired charging tops the battery to 50 % in about 15 minutes and reaches 100 % in 30 minutes. Wireless charging at 30 W is also supported, and reverse wireless charging at 10 W allows the phone to power accessories.
Pricing, Availability, and Software
At launch the S27 Ultra commanded a $1,399 MSRP, positioned just below the S26 Ultra’s pre‑price‑increase $1,399 figure. By December 2025, the phone has seen modest price drops; major retailers such as Amazon, Best Buy, and Samsung’s online store now list it around $1,199, with carrier subsidies often bringing the effective cost below $900 for trade‑in customers.
The device ships with Android 15 and Samsung’s One UI 7 out of the box. Samsung has released three major OS updates and monthly security patches through December 2025, with plans to support the phone until early 2027. New features added in the latest update include enhanced AI photography controls, a redesigned Quick Settings panel, and deeper integration with Samsung’s ecosystem (SmartThings, Galaxy Wearables, and the upcoming Galaxy AI services).
How the S27 Ultra Compares to the S26 Ultra
Performance
In head‑to‑head benchmarks, the S27 Ultra edges out the S26 Ultra by roughly 8 % in synthetic tests, thanks to the newer Snapdragon 8 Gen 3 core architecture. Real‑world tasks—such as multitasking, gaming at high frame rates, and AI‑driven photo processing—show a smoother experience with fewer thermal throttling incidents. The S27 Ultra also benefits from an improved cooling system, keeping temperatures lower during intensive sessions.
Camera Quality
Camera comparisons reveal the most noticeable gains on the ultra‑wide and telephoto lenses. The S27 Ultra’s 50 MP telephoto sensor offers a more natural zoom range and better distortion correction, while the ultrawide lens captures richer colors and less vignetting. The main 200 MP sensor’s larger pixel size improves low‑light performance, delivering cleaner images at higher ISO settings.
In terms of software, the S27 Ultra receives more frequent AI‑enhancements and smoother UI animations, whereas the S26 Ultra’s One UI 6 felt more static after two major updates.
“If you’re upgrading from an S26 Ultra, the S27 Ultra’s improvements in speed, battery life, and camera versatility are substantial enough to justify the modest price premium.” – The Verge, December 2025
Overall, the S27 Ultra solidifies Samsung’s position at the top of the Android flagship market, offering a balanced mix of display brilliance, robust performance, and versatile imaging capabilities. Its continued software support and occasional price reductions make it an attractive option for both new buyers and those looking to upgrade from the previous generation.
