OnePlus 12 Review: The 2023 Flagship Killer with Snapdragon 8 Gen 3

The OnePlus 12, launched in December 2023, is the company’s most ambitious flagship yet. Packed with the latest Snapdragon 8 Gen 3 processor, a stunning 6.82-inch AMOLED display, Hasselblad-powered cameras, and super-fast 100W wired + 50W wireless charging, the OnePlus 12 promises to deliver an ultra-premium experience without the extreme price tag of other flagships.

But does it truly live up to expectations? Let’s take a deep dive into its design, performance, camera, battery life, pros & cons, and real-world usage to find out.

🌈 Design & Display

OnePlus has always focused on premium aesthetics, and the OnePlus 12 takes it to another level. Sporting a 6.82-inch AMOLED panel with 1440×3216 pixel resolution, 120Hz refresh rate, and HDR10+, this display is among the best in its segment.

With LTPO technology, the screen can dynamically switch between 1Hz and 120Hz, optimizing both battery and smoothness. What truly stands out is its peak brightness of up to 4,500 nits, making it one of the brightest displays on any smartphone to date.

Protected by Corning Gorilla Glass Victus 2 and rated IP65 for dust and splash resistance, the phone is durable enough for everyday use. The design comes in Flowy Emerald, Silky Black, and Silver, offering elegance with a solid 220g build.

⚙️ Performance & Hardware

At the heart of the OnePlus 12 is the Qualcomm Snapdragon 8 Gen 3 (4nm) chipset paired with the Adreno 750 GPU. This powerful combo ensures top-class performance whether you’re multitasking, gaming, or using heavy productivity apps.

Its octa-core CPU structure includes:

• 1x Cortex-X3 @ 3.3GHz (Prime core)

• 3x Cortex-A710 @ 3.2GHz

• 2x Cortex-A710 @ 3.0GHz

• 2x Cortex-A510 @ 3.0GHz

This setup delivers AI-driven efficiency, blazing fast speeds, and strong gaming capabilities. Benchmarks show its dominance:

• AnTuTu v10 Score: 1,821,801+

• Geekbench 6 Single-Core: ~2180

• Geekbench 6 Multi-Core: ~6735

The OnePlus 12 runs on OxygenOS 14 based on Android 14, offering a clean and fluid interface with 4 years of major updates and 5 years of security patches.

💾 Memory & Storage

The device comes in multiple RAM and storage options, catering to both casual and power users:

• 12GB RAM + 256GB storage

• 16GB RAM + 256GB storage

• 16GB RAM + 512GB storage

• 16GB RAM + 1TB storage

• 24GB RAM + 1TB storage

With UFS 4.0 storage, users enjoy lightning-fast app launches and transfer speeds. The downside? No microSD card slot, so storage cannot be expanded.

📷 Camera Performance

OnePlus has partnered with Hasselblad to fine-tune the camera system, and it shows. The triple rear camera setup includes:

• 50MP Main sensor (OIS, HDR)

• 64MP Telephoto with 3x zoom

• 48MP Ultrawide / Macro sensor

Daytime shots are sharp with natural colors, while nighttime performance is impressive thanks to improved algorithms and OIS. The telephoto lens does a decent job, but it still lags slightly behind some ultra-flagships like Samsung Galaxy S Ultra.

For video, the phone supports 8K at 24fps, 4K at 60fps, and 1080p slow-motion at 480fps with Gyro-EIS stabilization.

The 32MP front camera delivers detailed selfies and supports 4K video recording, making it ideal for vloggers and video calls.

🔋 Battery & Charging

Powering the OnePlus 12 is a 5110mAh battery that offers all-day endurance. The highlight is its 100W wired charging, capable of filling the battery in just ~26 minutes.

Additionally, the phone supports 50W wireless charging and 10W reverse wireless charging, making it one of the most versatile charging systems available today.

📡 Connectivity & Audio

The OnePlus 12 covers all modern connectivity standards, including:

• 5G, 4G LTE, Dual SIM

• Wi-Fi 802.11

• Bluetooth 5.3

• NFC + Infrared port

• USB Type-C 3.0 with OTG

On the audio side, stereo speakers with Dolby Atmos deliver immersive sound. However, there’s no 3.5mm headphone jack, pushing users towards wireless or Type-C audio solutions.

🧪 Gaming & Real-World Performance

Gamers will love the Snapdragon 8 Gen 3 + Adreno 750 GPU combination. Games like Genshin Impact, BGMI, and Call of Duty run flawlessly on max graphics settings with consistent frame rates.

That said, during extended gaming sessions, the phone tends to get warm, though it manages thermal throttling well compared to older generations.
