The itel S25 is part of the S Series lineup that launched in November 2024, and while it sits in the mid-range category, the display is one area where it clearly tries to punch above its class. The phone carries a large 6.78-inch AMOLED panel running at 1080 × 2436 pixels, which translates to a sharp, vibrant screen that makes streaming, social media, and everyday browsing genuinely enjoyable on the S681LN. Smooth 120Hz refresh rate means the whole experience feels responsive and fluid something that was largely a premium feature not too long ago. Where it really stands out though is brightness a 1800 nits peak means the screen stays fully readable even in harsh outdoor sunlight, and the 1200 nits high brightness mode handles most real-world lighting situations with ease. Running Android 14 out of the box on a dual SIM 4G setup, and slipping into a slim 6.9mm frame, the S25 manages to offer a premium-feeling display experience without the premium price tag. For a mid-range phone, that screen alone gives it a strong first impression.
The itel S25 runs on the Unisoc T620, an octa-core chip built on a 12nm process that splits its workload between two faster Cortex-A75 cores topping out at 2.2GHz and six efficiency-focused Cortex-A55 cores a configuration that works well enough for daily tasks like browsing, messaging, and light app usage. The AnTuTu score of around 440K and a boot time of roughly 30 seconds are both reasonable figures, and paired with the ARM Mali-G57 GPU, the phone can handle casual gaming without breaking a sweat. That said, it’s worth being upfront the T620 is not a 2024 chip, and anyone expecting smooth performance on graphically demanding games or heavy multitasking will feel its limits fairly quickly.
The itel S25 comes in two variants a base 6GB option and a more capable 8GB configuration, both paired with 128GB of internal storage giving buyers a straightforward choice based on how much multitasking they expect to do. The 8GB LPDDR4X RAM handles everyday app switching and background processes without much complaint, and most users running social media, streaming apps, and messaging simultaneously will find things stay reasonably smooth. Storage runs on UFS 2.2.
The itel S25 keeps things simple on the camera front with a single 50MP rear shooter, but the choice of sensor here is worth noting. it uses the Samsung ISOCELL JN1, a well-regarded sensor that does a solid job capturing detail and managing colors in decent lighting conditions, producing images at a generous 8160 × 6144 pixel resolution that gives you real flexibility when cropping or editing shots after the fact. A 10x digital zoom is on board for reaching distant subjects, though as with most digital zoom implementations, quality drops off noticeably beyond the first few steps so it’s best used sparingly. Video tops out at 1080p at 30fps, which covers everyday recording needs comfortably think family moments, travel clips, and social content even if it doesn’t offer the 2K option found on the Ultra model. The ring-LED flash on the rear is a practical addition for low-light shots, giving more even illumination compared to a standard single LED. On the selfie side, the 32MP front camera powered by the Samsung ISOCELL GD2 sensor is genuinely one of the stronger points of this phone, resolving fine detail at 6528 × 4896 pixels and producing portraits and video calls that look natural and well-exposed.
The itel S25 carries a 5000mAh Li-Polymer with 18W wired fast charging brings it back up at a functional pace, though it’s worth being honest that 18W is on the slower end of what the market offers in 2024 and heavier users will notice the wait. At 185 grams the phone is a touch heavier than the Ultra model, though the plastic frame and back keep production costs down and help explain the accessible price point. Connectivity is well covered with Wi-Fi 5, Bluetooth 5.0, and NFC on board the NFC support is a genuine plus for a phone at this level, making contactless payments a practical daily option. The front-mounted fingerprint sensor is quick and reliable for unlocking, the single mono speaker handles casual audio adequately without impressing, and the RGB ring notification light adds a bit of visual character that makes the S25 feel a little more distinct on a crowded shelf.
