Performance & Gaming: Powered by Snapdragon 8 Gen 3
Both phones house the powerful Snapdragon 8 Gen 3 processor, which means ultra-smooth multitasking, top-tier gaming, and efficient thermal management. Benchmarks place them neck-to-neck, but OnePlus edges out slightly with its optimized OxygenOS and cooling tech.
Gamers will appreciate the responsive touch sampling rate, HDR gaming support, and vapor chamber cooling on both models. If you’re playing BGMI, Genshin Impact, or Call of Duty Mobile — expect flawless performance.
Battery & Charging: Long-Lasting Flagships
When it comes to battery life, OnePlus takes the upper hand with a bigger 5400mAh battery and super-fast 100W wired charging. Xiaomi counters with its own 90W fast charge but slightly smaller 5000mAh battery.
Both support 50W wireless charging, which is a plus for users on the go or using wireless charging pads. Real-world battery life should easily stretch to a full day with moderate to heavy use.
Software & User Experience: OxygenOS vs HyperOS
OnePlus continues to refine its clean and responsive OxygenOS, delivering near-stock Android vibes with a few added features. On the other hand, Xiaomi’s HyperOS is a new evolution of MIUI — faster, more secure, and optimized for flagship hardware.
However, OnePlus users often prefer its bloatware-free interface and timely updates. Xiaomi is catching up fast, but software preference will largely depend on the user.
Pricing & Value for Money
In terms of price-to-performance, OnePlus 12 Pro could be the better value at a slightly lower price point, without compromising on quality. Xiaomi, however, throws in a superior camera and more sensor features, justifying its higher price for photography and tech enthusiasts.
