Comparing two 2025 giants built for power and prestige

The OnePlus 15 and Vivo X110 Pro are two of the most ambitious Android flagships of 2025, each pushing the limits of smartphone performance and design. Both brands share a reputation for innovation, but their approach to delivering the “ultimate flagship” experience differs significantly. For UK buyers, this matchup highlights the balance between raw power, camera performance, and real-world usability.

Starting with the display, the OnePlus 15 features a 6.78-inch LTPO AMOLED screen with 1.5K resolution and an ultra-smooth 165Hz refresh rate. It supports HDR10+ and boasts brightness levels reaching nearly 1,800 nits, making it ideal for outdoor use and gaming. The Vivo X110 Pro counters with a slightly larger 6.82-inch AMOLED panel at 144Hz. While it’s equally vibrant and sharp, the OnePlus display wins for its adaptive refresh range, which can scale as low as 1Hz to save power during idle use.

Under the hood, the OnePlus 15 is powered by Qualcomm’s Snapdragon 8 Elite Gen 5 — the most advanced chip in the Android ecosystem. It delivers faster AI processing, superior gaming stability, and improved energy efficiency. The Vivo X110 Pro, on the other hand, is expected to run on MediaTek’s Dimensity 9400 chip. While also built on a 3nm process and strong in CPU performance, Qualcomm’s integrated GPU and AI engine give the OnePlus a slight advantage in raw performance and long-term optimisation.

When it comes to cameras, both brands are flexing their strengths. The OnePlus 15 continues its partnership with Hasselblad, featuring a triple 50MP setup with wide, ultra-wide, and telephoto lenses. Its image processing is tuned for realistic colours and strong dynamic range. The Vivo X110 Pro also features a triple 50MP array, but Vivo’s reputation for imaging is even stronger, especially in portrait and low-light photography. The X110 Pro’s new sensor, co-engineered with Zeiss, captures richer tones and improved depth-of-field, putting it neck-and-neck with the OnePlus in camera versatility.

Battery performance is another area of stark contrast. The OnePlus 15 packs a 7,300 mAh silicon-carbon dual-cell battery — the largest of any flagship this year. It supports 120W wired and 50W wireless charging, offering exceptional endurance and convenience. The Vivo X110 Pro’s smaller 5,500 mAh battery charges faster at up to 200W wired, but shorter lifespan and heat management could affect long-term durability. For users who value reliability over speed, the OnePlus 15’s balance of capacity and cooling gives it a clear edge.

In terms of build and materials, the OnePlus 15’s “Sand Storm” edition stands out with an aerospace-grade Micro-Arc Oxidation (MAO) coating and fibreglass composite back. It’s tougher than glass, more resistant to scratches, and visually striking. The Vivo X110 Pro takes a more classic route with curved glass panels and a metal frame, offering a sleek but traditional look. Both devices are IP68-rated, ensuring water and dust resistance for everyday durability.

Software is where philosophies diverge. The OnePlus 15 runs OxygenOS 16, based on Android 15, offering a clean, fast, and highly responsive interface with minimal bloatware. The Vivo X110 Pro runs Funtouch OS 15, also built on Android 15, which is feature-rich but slightly heavier. OnePlus promises five years of updates compared to Vivo’s expected four, making it a stronger choice for long-term users.

Audio, connectivity, and extras are competitive across both. Each features dual stereo speakers, advanced haptic motors, 5G, Wi-Fi 7, and NFC. However, the OnePlus 15 includes an upgraded X-Axis haptic feedback engine and a refined vibration tuning system, enhancing its gaming and typing experience. The X110 Pro counters with better in-display audio enhancement and slightly superior mic quality for video recording.

Pricing will likely determine the winner for many UK buyers. The OnePlus 15 is expected to launch around £850–£900, positioning it as a premium flagship, while the Vivo X110 Pro is rumoured to start closer to £750. That price difference could make the Vivo more tempting for those who prioritise camera performance and fast charging over sheer endurance.

In conclusion, the OnePlus 15 edges out the Vivo X110 Pro in overall balance — offering superior battery life, display fluidity, and long-term reliability. Vivo’s X110 Pro, meanwhile, takes the crown for camera sophistication and value. The real winner depends on your priorities: the OnePlus 15 is the powerhouse for performance purists, while the Vivo X110 Pro is the artistic choice for camera lovers seeking flagship-level quality at a slightly lower price.
