Design
At first glance, the Itel S25 Ultra’s design immediately evokes the aesthetic of high-end devices, with subtle cues that bring to mind the Samsung Galaxy S24 Ultra. This resemblance is particularly noticeable in its sleek lines and the prominent camera ring arrangement, giving the device a polished, modern look.
The itel S25 Ultra stands out as a stunning budget-friendly phone, offering a slim and lightweight profile that makes it easy to handle and use throughout the day. It has a thickness of just 6.9mm and a weight of 163 grams; thus, it feels remarkably slim and well-balanced in the hand. Its curved plastic frame, finished with a matte surface, not only enhances durability but also provides a solid grip, ensuring the phone feels comfortable and secure during use.
The front of the device is dominated by a stunning 6.78-inch display with 3D curved edges, surrounded by ultra-thin bezels for a nearly borderless, immersive viewing experience. A small punch-hole at the top-center houses the front camera, seamlessly blending into the design and providing an uninterrupted display for an engaging, modern touch.
Moreover, the itel S25 Ultra boasts an IP64 rating, making it resistant to dust and light splashes, adding an extra layer of reliability for users in various environments.
On the rear, the device features a clean, minimalist look, with the ‘Itel’ branding subtly placed at the bottom. The camera module, located at the top left, houses three camera lenses, accompanied by an LED flash and an auxiliary lens, which together create a well-balanced and sophisticated design. The matte plastic rear panel contributes to the phone’s elegant appearance while helping to reduce fingerprints and smudges, though light marks can still accumulate over time.
This smartphone is available in three eye-catching colors: Bromo Black, Komodo Ocean, and Meteor Titanium. The Meteor Titanium variant, in particular, shines with its sophisticated matte-finished back panel. While this finish adds a premium touch, it is prone to collecting fingerprints and smudges, so regular cleaning or the use of a protective case is recommended to maintain its pristine look.
The button placement on the itel S25 Ultra is thoughtfully designed for ease of use and accessibility. The power button, integrated with a fingerprint sensor, is conveniently located on the right side, offering quick and secure access to the device.
Just above it, the volume rocker is positioned for effortless control of sound while holding the Android phone. On the left side, the SIM card tray allows for dual SIM cards and expandable storage. At the bottom, the USB-C port is centrally placed for charging and data transfer, accompanied by a speaker grille and microphone.
