2. Design and Display
Build and Feel
The OnePlus 16 features a premium glass-and-aluminum construction, with Crystal Shield Glass protecting the front and back. Buyers can also choose a glass-fiber-reinforced plastic back variant. Its IP68/IP69K certification provides additional protection against dust and water, making it a practical choice for users who need better durability. The Xiaomi 18 Pro uses Dragon Crystal Glass 3 and an aluminum frame, with IP68 protection and water resistance up to 6 meters. Its compact design makes one-handed operation more convenient.
Display Quality
The OnePlus 16 features a 6.78-inch LTPO AMOLED display with a 185Hz refresh rate, Dolby Vision and HDR10+ support. Its exceptionally high refresh rate makes it particularly appealing for gaming and fluid navigation. The Xiaomi 18 Pro counters with a 6.4-inch LTPO AMOLED panel, 120Hz refresh rate and an impressive 4000-nit peak brightness. It also includes a 2.7-inch secondary rear display for notifications and camera previews.
Verdict
OnePlus wins for smoother visuals and durability, while Xiaomi offers better outdoor brightness and a useful secondary screen. The choice depends on display priorities.
3. Specifications Including Battery
Performance
The OnePlus 16 runs on the Snapdragon 8 Elite Extreme Gen 6, while the Xiaomi 18 Pro uses the Snapdragon 8 Elite Gen 6. Both chipsets are manufactured using a 2nm process and promise flagship-grade performance. However, OnePlus has an advantage on paper with its higher-tier chipset and Adreno 850 GPU. Both phones offer up to 16GB RAM and 1TB UFS 4.1 storage, providing plenty of room for demanding applications, multitasking and large files. OxygenOS 17 and HyperOS 4 bring Android 17 experiences with different software approaches.
Battery and Charging
Battery capacity is a major advantage for OnePlus. Its 9000mAh silicon-carbon battery comfortably exceeds the Xiaomi 18 Pro’s 7000mAh unit. Both support 100W wired and 50W wireless charging, but OnePlus adds 5W reverse wired charging, reverse wireless charging and bypass charging. Xiaomi offers 27W reverse wireless charging, which is particularly useful for powering accessories. The OnePlus 16 is clearly better equipped for extended gaming sessions and heavy daily usage.
Verdict
OnePlus takes the performance and battery categories with its higher-tier processor, larger battery and additional charging features. Xiaomi remains powerful but cannot match its endurance advantage.
4. Camera
Main and Secondary Lenses
The Xiaomi 18 Pro has a stronger photography-focused camera setup, featuring a 200MP main sensor with a larger 1/1.28-inch sensor size and a 200MP periscope telephoto camera with 3.2x optical zoom. Leica lens technology further strengthens its photography credentials. The OnePlus 16 also features a 200MP main camera, but pairs it with a 50MP telephoto lens offering 3x optical zoom and a 50MP ultrawide camera. Xiaomi’s higher-resolution periscope camera should offer greater flexibility for detailed zoom photography. Both phones support 8K recording and 4K video at up to 120fps.
Selfie Camera
Both smartphones feature 50MP front cameras with autofocus and 4K video recording at 60fps. However, their approaches differ slightly. The OnePlus 16 uses an ultrawide selfie camera, making it more suitable for group selfies and wider compositions. Xiaomi opts for a standard wide-angle camera with PDAF, alongside HDR10+ video support. Its front camera should appeal to users who prioritise detailed portraits and video recording. Neither phone makes significant compromises in selfie hardware, although OnePlus offers a wider perspective.
Verdict
Xiaomi wins the camera category with its larger main sensor, 200MP periscope camera and Leica tuning. OnePlus remains versatile, but Xiaomi offers more advanced photography hardware.
5. Pricing
The OnePlus 16 is priced around $900 (approximately ₹86,000), positioning it as the more affordable flagship. The Xiaomi 18 Pro is priced around $1,000 (approximately ₹1,20,000), carrying a noticeable premium. Both smartphones offer up to 16GB RAM and 1TB storage, so the difference is not simply about memory configurations. Instead, Xiaomi’s higher asking price reflects its advanced camera hardware, secondary rear display and premium photography features. OnePlus offers a more aggressive combination of processing power, battery capacity and display technology at a lower entry price.
Verdict
OnePlus offers better value with its lower price, larger battery and powerful hardware. Xiaomi justifies its premium mainly through superior camera capabilities.

6. Conclusion
The OnePlus 16 stands out with its 185Hz LTPO AMOLED display, Snapdragon 8 Elite Extreme Gen 6 processor and massive 9000mAh battery. Its IP68/IP69K protection and extensive charging options also make it a compelling everyday flagship. The Xiaomi 18 Pro brings a different set of advantages, including a 200MP periscope camera, Leica photography features, a brighter 4000-nit display and a secondary rear screen.

Both devices offer premium software experiences, fast storage and capable front cameras.
Verdict
OnePlus 16 is the overall winner for its stronger performance positioning, exceptional battery capacity, smoother display and better value for money. It is the more practical flagship for most users. However, the Xiaomi 18 Pro is the better choice for photography enthusiasts who want advanced zoom capabilities, Leica tuning and a distinctive secondary display.
