OnePlus has officially launched its new slim 5G smartphone for 2025, setting a new benchmark in minimalist design and performance engineering. Known for its clean aesthetics and lightning-fast software, OnePlus has once again captured attention with a phone that’s not only powerful but also incredibly slim, elegant, and premium. With a sleek build, advanced camera system, and refined OxygenOS experience, this phone aims to deliver an ideal blend of sophistication and performance for modern Indian consumers.
Slim and Sleek Design Philosophy
The OnePlus Slim 5G (2025) is a design marvel — just 7.2mm thick, it’s one of the thinnest OnePlus smartphones ever built. The brand has crafted the frame using aircraft-grade aluminum alloy, ensuring durability without adding extra weight. The phone’s back panel features nano-textured matte glass, providing a satin-smooth feel and fingerprint resistance.
The new camera module design follows a clean dual-ring layout, giving it a minimalist aesthetic while maintaining a symmetrical appeal. Despite its ultra-slim profile, the device feels sturdy and premium. The weight is kept at just 176 grams, making it exceptionally lightweight for daily use.
Available in three elegant finishes — Frosted Silver, Midnight Violet, and Obsidian Black — the OnePlus Slim 5G is clearly designed for those who value craftsmanship. Every detail, from the curved edges to the polished aluminum buttons, showcases OnePlus’s dedication to refined industrial design.
Display: A Feast for the Eyes
The smartphone features a 6.73-inch Full HD+ Fluid AMOLED display with a 120Hz adaptive refresh rate and HDR10+ certification, offering buttery-smooth visuals and excellent contrast levels. The screen supports 1.07 billion colors and achieves a peak brightness of 1,800 nits, ensuring vibrant clarity even under harsh sunlight.
The panel offers LTPO 3.0 technology, automatically adjusting refresh rates between 1Hz and 120Hz for optimal performance and battery efficiency. The narrow bezels and centrally aligned punch-hole camera enhance the immersive feel, providing a 93% screen-to-body ratio.
Color accuracy is calibrated to near perfection, making it ideal for both content consumption and professional editing tasks. OnePlus’s AI Display Optimizer also enhances brightness and sharpness dynamically, while Eye Comfort Shield reduces blue light strain for prolonged use.
Camera System: Designed for Precision
The OnePlus Slim 5G comes with a powerful triple rear camera setup, tuned with the brand’s Hasselblad Color Science 3.0 for realistic tones and superior balance. The camera array consists of a 50MP Sony IMX890 primary sensor with OIS, a 32MP telephoto lens with 2x optical zoom, and a 48MP ultra-wide lens with a 115° field of view.
The main sensor captures stunning detail with deep contrast and natural colors. The Pro HDR Engine ensures accurate lighting even in complex environments, while the AI Portrait Mode refines edge detection and background blur for DSLR-like results. The Nightscape Pro Mode improves low-light shots, producing bright and clear images with minimal noise.
On the front, a 32MP selfie camera captures crisp, natural-looking images with AI Beautify and Smart Exposure Control, making it perfect for both social media content and professional portraits.
The camera system also supports 8K video recording at 30fps and 4K at 60fps, with advanced stabilization via Ultra Steady Mode 2.0. New creative tools like Cinematic Filters and Dual View Video allow users to experiment with unique styles and perspectives.
Performance and Power
Under the hood, the OnePlus Slim 5G runs on the latest Qualcomm Snapdragon 8s Gen 3 chipset, built on a 4nm architecture for exceptional power efficiency and high performance. The CPU delivers blazing-fast speeds for gaming, multitasking, and creative workloads, supported by the Adreno 735 GPU for next-level graphics rendering.
The phone comes in two variants — 8GB/128GB and 12GB/256GB — using LPDDR5X RAM and UFS 4.0 storage, ensuring fast app launches and smooth multitasking.
It runs OxygenOS 15 based on Android 15, providing a lightweight, clean, and responsive experience. The software integrates AI Smart Mode, which optimizes performance based on user habits, and Game Mode 3.0, which ensures lag-free gaming with advanced cooling.
To handle heat dissipation in its slim frame, OnePlus has implemented a nano-graphene cooling system — a newly engineered design that efficiently manages temperature while maintaining consistent performance even during extended gaming or 4K video recording.
Battery and Charging
Despite its ultra-slim body, the OnePlus Slim 5G houses a 4,700mAh battery, optimized through AI-assisted energy management. The phone supports 100W SuperVOOC fast charging, capable of charging from 0% to 100% in just 25 minutes.
OnePlus’s Battery Health Engine extends long-term battery durability, maintaining 80% capacity even after 1,000 charging cycles. The device also supports 30W wireless charging and reverse wireless charging for accessories.
For light users, the battery easily lasts a full day, while moderate users can expect around 8–9 hours of continuous screen time. The intelligent Sleep Charging Mode prevents overcharging overnight, ensuring stable battery health.
Connectivity and Features
The OnePlus Slim 5G is loaded with the latest connectivity options, including Dual 5G SIM, Wi-Fi 7, Bluetooth 5.4, NFC, and USB 3.2 Type-C. It also features Dolby Atmos stereo speakers with Hi-Res certification, offering powerful sound for music and movies.
Security is handled by an in-display ultrasonic fingerprint sensor and AI-based face unlock, both extremely fast and reliable. The device is IP68 rated, providing water and dust resistance.
Other useful additions include multi-device sync, AI Call Noise Cancellation, Always-On Display 3.0, and OnePlus File Share, which allows fast transfers between OnePlus and OPPO ecosystem devices.

Why the OnePlus Slim 5G Stands Out
The OnePlus Slim New Phone (2025) is more than just a slimmer device — it’s an expression of design precision and practical innovation. It blends an ultra-thin body with premium build quality, top-tier performance, and reliable battery optimization, making it one of the most balanced smartphones of the year.
This model is ideal for users who prefer elegance and comfort without sacrificing performance. The lightweight structure, 100W charging, and Hasselblad-tuned camera make it both a performance powerhouse and a lifestyle statement.
In 2025, OnePlus has truly proved that thin doesn’t mean compromise — the Slim 5G combines form, function, and finesse in perfect proportion, cementing its place among the best premium smartphones in India.
