Based on a review by TechTalkTV (accessed 2026-07-26).
Based on this review alone: skip it — the dedicated 3x telephoto camera is reportedly being removed, unless expected larger battery capacity (silicon-carbon) without increasing phone thickness is your only priority.
The reviewer concludes that the Galaxy S27 Ultra has become "a lot more interesting" due to the revealed updates. They also confidently state that concerns about silicon-carbon batteries degrading faster are unfounded, believing there's "no real evidence" for this in everyday use.
This video from TechTalkTV discusses leaked information and rumors about the upcoming Samsung Galaxy S27 Ultra. It covers anticipated features such as silicon-carbon batteries and significant changes to the camera system, alongside an expected S27 Pro model and software enhancements like Privacy Display in One UI 9.
The anticipated Galaxy S27 Ultra is shaping up to be a compelling flagship with rumored advancements in battery and camera technology. Samsung is expected to integrate silicon-carbon batteries, enabling a larger capacity without increasing the phone's thickness, a significant improvement after years of stagnant battery size. However, the report of a removed 3x telephoto camera could be a drawback for users who frequently utilize that specific focal length. These expected changes position the S27 Ultra as a strong contender for those prioritizing cutting-edge battery innovation and versatile camera hardware. If you value a slim phone with extended battery life and updated sensors, these leaks suggest a worthwhile upgrade; however, consider alternatives if a dedicated 3x telephoto lens is essential for your use.

Samsung surprised everyone at Unpacked by revealing that the entire Galaxy Z Fold 8 lineup uses silicon-carbon batteries, which was impressive as it stayed under wraps.

It's almost definite that the Galaxy S27 Ultra will also get silicon-carbon batteries, supporting earlier rumors of an increased battery capacity for the device.
reviewer_claimpositivet=1:07–1:25
The biggest advantage of silicon-carbon batteries is their ability to pack more battery into the same amount of space, potentially allowing the S27 Ultra to be thinner while still getting a larger battery.

Some articles claim silicon-carbon batteries wear out faster, citing new EU battery labels rating phones like the Z Fold 8 for 1,200 charge cycles, down from a previous 2,000 cycles.

The S26 Ultra, which doesn't use a silicon-carbon battery, also dropped from 2,000 to 1,200 cycles under the new EU rating, suggesting the change is not solely due to silicon-carbon technology.

The more likely explanation for the battery cycle rating change is a new standardized EU battery testing system that became mandatory in July 2025, making older and newer numbers not directly comparable.

There is currently no real evidence that Samsung's silicon-carbon batteries degrade any faster in everyday use.

The S27 Ultra's ultrawide camera will get a new Sony sensor, the main camera a new in-house 200MP sensor, and the dedicated 3x telephoto camera will be removed, retaining the 50MP 5x periscope.

The S27 Ultra is expected to feature a new 16MP square selfie camera, similar to Apple's latest iPhones, allowing automatic switching between portrait and landscape selfies.

Due to camera changes, both the S27 Pro and S27 Ultra are expected to feature a new horizontal camera layout, based on concept images from current leaks.

Samsung is extending the Privacy Display feature to all four S27 models, making it no longer exclusive to the Ultra lineup.

With One UI 9, Privacy Display will only protect the floating Picture-in-Picture window, allowing the rest of the screen to remain normal, which makes the feature more practical.
The reviewer states that after the surprise reveal of silicon-carbon batteries in the Z Fold 8 lineup, it's "almost definitely yes" for the S27 Ultra to also receive them. This change is linked to Samsung's plan to increase battery capacity on the Ultra model.
While some articles claim faster wear based on new EU battery labels (1,200 cycles vs. old 2,000), the reviewer explains this is likely due to a new standardized testing system. The S26 Ultra, which lacks silicon-carbon, also received the 1,200-cycle rating, supporting the idea of a testing change rather than battery quality drop.
The S27 Ultra is expected to feature a new Sony sensor for the ultrawide camera and a new in-house 200MP sensor for the main camera. The dedicated 3x telephoto camera is reportedly being removed, while the 50MP 5x periscope camera will remain.
The S27 Ultra is expected to feature a new 16MP selfie camera with a square sensor, similar to Apple's latest iPhones, which enables automatic switching between portrait and landscape modes without manual rotation.
Samsung is extending the Privacy Display feature, which was previously exclusive to the Ultra, to all models in the S27 lineup. This indicates a wider availability of the privacy-enhancing feature.
With One UI 9, the Privacy Display feature is improved so that if it's enabled for an app like YouTube and the video is minimized to Picture-in-Picture (PiP) mode, only the PiP window remains protected. The rest of the screen returns to normal brightness, making the feature more practical and less intrusive on overall phone usage.
