Body & Design

This model features a sleek, curved-edge AMOLED display and a slim profile. The body is about 6.9 mm thick and weighs approximately 163 grams, making it relatively lightweight for its feature set. The device is offered in multiple colours including Bromo Black, Meteor Titanium and Komodo Ocean. The back panel includes an accent “ring” around the camera module, and the finish gives a premium look despite the affordable price tier.

Display

The phone has a 6.78-inch AMOLED screen with a resolution of 1080 × 2436 pixels, yielding about ~393 ppi. The display supports a 120 Hz refresh rate, ensuring smooth transitions and animations. It is protected by Corning Gorilla Glass 7i and in some listings offers peak brightness up to around 1400 nits for good outdoor visibility.

Performance (Hardware & Software)

Under the hood the S25 Ultra is powered by a Unisoc Tiger T620 chipset, built on a 12 nm process. The CPU comprises 2 × Cortex‐A75 cores (up to ~2.2 GHz) and 6 × Cortex‐A55 cores (up to ~1.8 GHz), with a Mali-G57 MP1 GPU handling graphics. With 8 GB RAM and 256 GB internal storage, the device offers solid performance for day-to-day use. It runs Android 14 with itel’s custom UI (itel OS 14.5). Virtual RAM extension features are also present in many markets.

Memory & Storage

This variant includes 256 GB of built-in storage, giving generous space for apps, photos, videos and offline media. External storage expansion via microSD is supported in many regions, so users can add further storage for large files if needed. Dual SIM support (Nano-SIM + Nano-SIM) is standard.

Camera System

On the rear the S25 Ultra features a 50-megapixel main camera (wide-angle) along with a very small auxiliary sensor (depth or macro assist) in some markets. The camera system supports a variety of modes including Super Night Mode, AI Scene Recognition, HDR, Panorama, and up to 1440p video recording at 30 fps, as well as 1080p video recording. On the front the selfie camera is a 32-megapixel sensor, allowing high-resolution selfies and 1080p/1440p video capture.

Battery & Charging

The device is powered by a 5,000 mAh non-removable battery, designed to deliver a full day of mixed usage. It supports 18 W wired fast charging via USB-C, enabling fairly quick top-ups and less time tethered to a charger.

Connectivity & Additional Features

Connectivity includes dual 4G LTE support, Wi-Fi (dual-band), Bluetooth (version 5.x), GPS/GLONASS/BeiDou positioning, USB-C port and in many regions a 3.5 mm headphone jack. The phone also features an under-display fingerprint sensor, face unlock, and an RGB notification ring around the rear camera module (in select models). The device carries an IP64 rating for basic dust and splash resistance in some markets.

Summary

The itel S25 Ultra (256 GB + 8 GB) offers an impressive combination of features for its price: a large, smooth high-refresh AMOLED display, generous RAM and storage, a capable camera system, up-to-date Android version, and a slim, lightweight design. While it lacks 5G connectivity and ultra-premium materials found in high-end phones, for many users—especially those in budget-sensitive markets—it offers excellent value.
