Galaxy S27 Ultra could impress Samsung fans if the silicon-carbon battery rumor turns out to be accurate. The company used the new battery solution in its foldable phones, and an expansion is reportedly planned for the flagship models.

Battery capacity has always remained the aspect Samsung has never gone aggressive on. While rivals aggressively adopted higher battery capacities, Samsung restrained and kept the size unchanged over the years.

Galaxy S27 Ultra to get silicon-carbon battery upgrade

A highly credible media outlet reported this week the potential battery capacities of the Galaxy S27 Pro and Galaxy S27 Ultra. The former is reportedly getting a 5,200mAh battery, while the latter is getting a 5,700mAh battery.

Samsung’s Galaxy S27 Pro could come compact, with the display reportedly measuring under 6.5 inches. Galaxy S27 Ultra may retain the size, and thickness could be improved further, yet a 5,700mAh battery is rumored.

Such upgrades can’t be made easily. That’s what indicates that the Korean tech giant may have decided to bring a silicon-carbon battery upgrade to next year’s Galaxy S27 Pro and Galaxy S27 Ultra flagship phones.

700mAh will be a big boost to Samsung’s top-tier flagship phone. If true, it’s going to be the first change in seven generations, starting with the Galaxy S20 Ultra. Seems like it took Samsung seven years to ramp up the battery by 700mAh.

Samsung’s silicon carbon battery has no durability concerns

Durability and long-term reliability have always been the primary concern with silicon-carbon battery solutions. The difference in internal architecture and elements renders the new battery tech less reliable than lithium-ion cells.

That said, Samsung took a different approach to eliminate that concern. Rather than just swapping in silicon, engineers redesigned the cathode, electrolyte, and separator alongside the new anode to keep that expansion in check.

July 2026 brought a flood of leaks and rumors of the Samsung Galaxy S26 FE. Through a combination of regulatory certifications, insider reports, and case leaks, we now have a nearly complete picture of what to expect from the next FE device.

Here is a complete breakdown of all major leaks and rumors of the Galaxy S26 FE that surfaced over the month.

Design, Cases, and Colors

The Galaxy S26 FE is expected to closely follow the design language of the mainline Galaxy S26 series, featuring an Armor Aluminum frame, an IP68 rating, and a vertically aligned triple-camera module.

Color Palette: A leak from Dealabs suggests the phone will be available in Graphite, Aqua Green, and a unique blue-purple blend.

Case Renders: Capping off the month’s news cycle on August 1, Android Headlines published an exclusive look at upcoming official accessories.

The leak showcased a “Clear Magnet Case” and a “Silicon Magnetic Case,” strongly hinting at magnetic charging support. The renders also showed off “Cobalt Violet” and “Mint” colorways and confirmed the phone will feature a silver frame.

Performance and Core Specs

Samsung appears to be positioning the S26 FE as a highly capable device, matching some of the hardware found in its premium 2025 foldables.

Processor: Industry rumors consistently point to the Exynos 2500 chip powering the device. This is the same 3nm architecture used in last year’s Galaxy Z Flip 7.

Display: Expect a 6.7-inch Dynamic AMOLED 2X screen with a 120Hz adaptive refresh rate and up to 2,600 nits of peak brightness.

Storage options: Unlike the mainline S26 series, which dropped its lowest storage tier, the S26 FE will reportedly still start at 128GB, alongside 256GB and 512GB configurations.

Camera setup

If you were hoping for a massive camera overhaul, July’s leaks might be slightly disappointing. The S26 FE is heavily rumored to reuse the exact same camera array as its predecessor:

• 50MP primary camera with OIS
• 12MP ultrawide camera
• 8MP telephoto lens with 3x optical zoom
• 12MP front-facing selfie camera

Battery, charging, and certifications

Late July saw the S26 FE pass through several key regulatory bodies, solidifying its hardware footprint:

FCC Certification: A July 31st FCC listing (model SM-S741U) confirmed the device is moving closer to launch and will retain 45W fast wired charging.

Battery Capacity: The phone is expected to house a 4,900mAh battery, a slight upgrade designed to easily last a full day of heavy use.

Qi2 Readiness: The Wireless Power Consortium (WPC) listing confirmed wireless charging capabilities and gave the public its first real-world glimpse of the device.

Combined with the magnetic cases leaked by Android Headlines, this strongly suggests the phone will support the magnetic Qi2 standard.

Pricing and release window

The Fan Edition is historically a budget-conscious alternative to Samsung’s flagships, but this year’s model might sting the wallet a bit more.

Price hike: A major leak regarding European pricing indicates a €50 increase across the board. The 128GB base model is slated to start at €749, the 256GB at €809, and the 512GB at €929.

While US pricing hasn’t been confirmed, a proportional hike could push the starting price to around $700 (up from the S25 FE’s $649 starting point).

Launch date: Multiple reports state that Samsung is targeting a release date around September 1, 2026, which would align perfectly with the IFA technology trade show in Berlin.

SammyFans Poll: Samsung’s One UI 9 software chapter has officially begun, but is it generating the usual excitement, or has update fatigue quietly set in among the fanbase?

One UI 9, built on top of Android 17, went official on July 22, 2026, arriving alongside the new Galaxy Z Fold 8 and Z Flip 8 lineup. That launch was really just the opening move, as the real test starts now, as Samsung shifts from “new phones get it first” mode into the much bigger job of pushing the update out to the rest of its device lineup.

The Galaxy Z Fold 8 series will see the full experience build land around August 7, and if past patterns hold, that will set the tone for how aggressively Samsung tackles the rest of the schedule.

Beta testing widens the net

Not everyone wants to wait for a new foldable to try new software, and Samsung knows that. The One UI 9 beta program is already active for the Galaxy S26 series in select markets, giving current flagship owners early access.

Galaxy S25 users should not feel left out for long either, with Beta access on the way soon. Once that happens, last year’s flagship buyers get their own hands on the latest software advancements and newly added AI features.

Even owners of the Galaxy S24 and S23 series aren’t being ignored. Internal testing is said to be progressing well behind the scenes, and a stable release for those devices could realistically show up as early as September.

One UI 9 brings refinement, not reinvention

What stands out about One UI 9 so far isn’t a dramatic redesign. It leans more toward Android 17 optimizations, smoother performance, and small but meaningful UI adjustments rather than anything that reshapes how the interface looks and feels.

So, where do you stand?

Are you genuinely looking forward to One UI 9, or has the excitement worn thin after years of iterative updates? Are you refreshing the Beta news daily, content to wait for the stable release, or simply happy running what you already have?

Samsung and Netflix are marking the launch of the Galaxy Z Fold 8 Ultra, Fold 8, and Flip 8 with a special event built around The East Palace.

Users of Samsung devices, both new and existing, can download five free themes and wallpapers along with matching icons that capture the mood of The East Palace.

The East Palace pack goes live through the Galaxy Store starting at 10:00 AM local time on July 30 and will remain available until September 10.

Free of charge, users can download five themes and wallpapers, along with icons, capturing the atmosphere of the East Palace and its signature pond, including Kkeomeoksari, the fan-favorite character often dubbed the “Joseon-era Groot.”

Samsung and Netflix have collaborated since 2019, and this isn’t their first theme drop. Past promotions tied to Stranger Things and KPop Demon Hunters gave fans similar ways to bring their favorite shows into daily use on their devices.

Samsung’s Galaxy Z Fold 8 series is designed with Netflix streaming as a priority. The inner display’s aspect ratio shifts from 10:9 to 4:3, cutting down the black bars above and below video so content fills more of the screen.

AI integration goes further too; Now Brief can surface Netflix recommendations or show exactly where a user left off based on schedule and usage patterns, even suggesting “Travel Ready” picks ahead of a trip.

Additionally, Samsung Finder lets users search for a title and pull up related content without opening the Netflix app. These upgrades come as part of the One UI 9 full experience, which is tailor-made for the new foldable phones.

Samsung officially introduced One UI 9 full experience on July 22 and the rollout is set to begin on August 7, but what about users of older Galaxy devices?

At Unpacked, Samsung didn’t talk about the One UI 9 rollout to existing users. We had high hopes from the press release, which, disappointingly, had nothing. Samsung mentioned something in footnotes, but that too lacked a timeline or window.

One UI 9 official launch and release

Samsung says One UI 9 official rollout begins on August 7. The newest foldable phones, Z Flip 8, Z Fold 8, and Z Fold 8 Ultra, will ship with the latest software.

Meanwhile, users rocking older Samsung flagship and mid-range phones have to wait. The company is unlikely to begin expansion of the software perks immediately after the foldables go on sale.

A look at One UI 7, One UI 8 and One UI 9 rollouts

Samsung’s Android 15-based One UI 7 was introduced in January 2025. The Galaxy S25 series flagships were shipped with the Stable version, but expansion to older devices started in April 2025.

Android 16-based One UI 8 was launched in July 2025. Galaxy Z Flip 7 and Z Fold 7 were the first to launch with the new software. However, Samsung kept the update restricted to the foldables until late September 2025.

One UI 8.5 also had a Beta Program, which was one of the longest-running Beta Programs. Beta launched in December 2025, the official debut happened in February 2026, but rollout to older devices commenced in May 2026.

The latest One UI 9, based on Android 17, landed in the Beta Program in May 2026. Since then, the company has been testing the software on the Galaxy S26 series, and there’s no solid information on expansion to older models.

When will your Samsung phone get One UI 9 update

For One UI 7 (Android 15) and One UI 8.5 (Android 16), the gap between official debut and stable rollout was about 75 days. Samsung took a similar duration of about 60 to 70 days to kickoff Stable One UI 8 rollout.

In the past three major rollouts, the company took more than two months. If Samsung maintains a familiar strategy, the One UI 9 update rollout may begin in mid to late September.

Galaxy S26 series, as anticipated, will be the first to receive the official update. At the same time, Samsung will run Beta testing activity on a wide range of devices before the stable rollout.

Disclaimer: Samsung has not shared the One UI 9 rollout timeline or roadmap. We expect the update to be available in September, but it is not certain. Update rollout depends on various aspects, including testing and verification.
