General Overview
This model is positioned within itel’s S-series as a premium budget smartphone offering. It ships with 8 GB of RAM and 128 GB of internal storage, giving ample space for apps and media. It runs a recent version of Android (Android 15 in some markets) with itel’s custom interface.

Body & Design
The phone features a large 6.78-inch curved AMOLED display, and uses premium materials such as a 3D-curved glass front protected by Corning Gorilla Glass 7i. The build is remarkably slim for the battery and feature set, measuring approximately 6.8–7.0 mm in thickness and weighing around 218 g according to one spec sheet. It also boasts an IP65 rating for dust and splash resistance.
Colour options include Beige, Blue, Gold, and Gray, giving users some style flexibility.

Display
The display is 6.78 inches in diagonal, using AMOLED technology with a “1.5K” resolution (around 1080 × 2436 pixels in some listings) and a very high refresh rate of 144 Hz. The screen is described as having curved edges (on the longer sides) for an immersive look, and a peak brightness claimed to be high (4500 nits in some listings).

Performance (Hardware & Software)
Inside, the S26 Ultra is powered by the Unisoc T7300 chipset built on a 6 nm process, delivering an octa-core CPU and Mali-G57 GPU for graphics. With 8 GB RAM (plus possible memory expansion) and 128 GB ROM (some markets offer 256 GB as an option), the phone handles everyday tasks comfortably. It runs Android 15 (in some regions), giving both modern features and expected longevity.

Memory & Storage
The internal storage is 128 GB in this variant, providing plenty of space out of the box. While some spec-sheets list no microSD expansion (depending on region), others mention support for external storage depending on market. Users wanting maximum media capacity should verify local variant details.

Camera System
The rear camera setup features a 50-megapixel primary sensor with wide-angle lens. Some sources list a 2-megapixel auxiliary depth sensor (or similar lens) as part of the rear system. The front camera is a 32-megapixel selfie unit. Video recording on the rear camera supports up to 1080p and in some listings up to 1440p (2K) at 30 fps.

Battery & Charging
Battery capacity is listed as 6,000 mAh in most sources, enabling a full day of mixed use. The phone supports 18 W fast wired charging through USB-C. Given the slim body and large battery, it provides a strong endurance profile.

Connectivity & Features
The device supports dual nano-SIM cards with LTE support (no confirmed 5G in all markets). Wireless connectivity includes Wi-Fi (dual band), Bluetooth (version 5.x in listings), GPS with A-GPS/GLONASS, and NFC in some regions. The phone includes a USB-C port, and retains a 3.5 mm headphone jack in many markets (though verify local release variant).
Security features include an in-display optical fingerprint sensor and face unlock. Additional features such as “six-year fluency guarantee” (promised software/firmware support), an AI assistant, rain-proof touch when the screen is wet, and IP65 splash/dust resistance are part of the marketing package.
