Design and Build Quality
Certainly, the Xiaomi 14 and OnePlus 12 are two absolutely gorgeous smartphones, but they have their own personalities. The OnePlus 12 is a bit of a chunky boy, thanks to 220 grams while the Xiaomi 14 has cut the tabs to be a weighty 193 grams. Besides, both phones are rocking some serious protection in Gorilla Glass, but there is more on the OnePlus 12 with the IP68 rating. This means immersing within 1.5 meters of water will be a shock to the phone for about 30 minutes.
The Xiaomi 14 however sits lower and has an IP65 rating hence not much water immersion is expected except for light splashes. Both are “dust resistant therefore no sweat for pocket fuzz!
Looking at the comprehensive design, although both usages will be apparent, the OnePlus 12 has a more rounded screen and feels more elegant whereas the Xiaomi 14 rather has a flat panel design. Turns out, it’s really a matter of personal preference here – some folks love the curved look, others find it a bit… extra.
Display
In terms of display, the OnePlus 12 is flexing hard with its 6.82-inch ProXDR LTPO curved display. It sports a jaw-dropping 1440×3168 px resolution (or QHD+, if you can’t quite bear to jump into the high-res mobile bandwagon) and pixel density of 510 ppi. The layman’s devices went mild with their 6.36 inches LTPO AMOLED display in the case of the Xiaomi 14. A 1200×2670 px resolution (FHD+) and 460 ppi on the other hand.
Not too shabby, but the OnePlus 12 definitely has the edge in pure pixel pushing power. Both phones have a buttery smooth 120Hz refresh rate, which means you get that scrolling we all love as it is very fluid. But let’s be real – If you are not a heavy mobile gamer or a pixel-peeping nut like some people, there simply isn’t going to be much of a difference in every day use.
Performance
Under the hood, both these bad boys are powered by Qualcomm’s beastly Snapdragon 8 Gen 3 chipset. When it comes to benchmark tests, the OnePlus 12 mostly manages to outperform the Xiaomi 14 by a very slim margin, but we are talking of milliseconds here. In regular use, there is little to no difference that you would notice. Both phones easily perform multitasking, gaming, editing and heavy apps.
Where they differ is in their approach to software. OnePlus’s OxygenOS has gained attention for its clean, streamlined interface that resonates deeply with users who prioritize efficiency and convenience. Xiaomi’s MIUI, while feature-packed, can feel a bit cluttered with what some might consider superfluous features.
Charging and Battery Life
The OnePlus 12 is packing a beefy 5400 mAh Li-Polymer battery, while the Xiaomi 14 keeps it tight with a 4610 mAh cell. But size isn’t everything, right?
Both phones support wireless charging, but OnePlus takes the cake with its 100W SUPERVOOC charging. It’ll juice up your phone from 0 to 100% in a mind-blowing 26 minutes! Xiaomi’s no slouch either, with its 90W HyperCharge getting you to full in 31 minutes.
In real-world use, the OnePlus 12 is a beast, lasting about 20 hours and 27 minutes of always-on up-time with mixed workloads. The Xiaomi 14 puts up a good fight, clocking in at almost 14 hours.
Camera Capabilities
Both phones are endowed with potent camera equipment. The Xiaomi 14 is equipped with triple rear cameras: the main 50-megapixel camera is availed with a bigger image sensor and a wide aperture of f/1.6, a 48-megapixel ultrawide, and a 64-megapixel telephoto that has 3x optical zoom.
On the other hand, the OnePlus 12 certainly does not joke around with a concept of three 50MP sensors that looks impressive. It has two JN1 main camera sensors that are utilized for its ultra-wide and telephoto making it really appealing to your Instagram feeds. Such configuration provides a flexible coverage from 14 to 75 mm which is suitable for both distant landscape photography and tight portraits.
Comparing the photographs produced by both phones, they will give you great photos in their own, however, the bonus point would go to the OnePlus 12 in terms of all-round ability.
Xiaomi 14 vs OnePlus 12 – Which One To Buy?
If aesthetic aspects are not so important for you and you need a pretty decent device, then Xiaomi 14 is just for you. It certainly costs you a fortune but there is a great display, responsive chipset, and camera setup to make all your friends envious.
But if you want the best of the best, OnePlus 12 is difficult to beat. The bigger and similar-looking curvy display is a sight to behold. That camera system is too good; it can capture anything and everything given to it. And, with its wider battery, more powerful chipset, and ridiculously fast charging, there is less time wasted on the wall.
Conclusion – Final Verdict!
Well look, I can safely say that whichever of these monsters you decide to go up against, One Plus 12 or Xiaomi 14, you cannot go wrong. They are both high-end handsets and are capable of handling all tasks without gleaming inappropriately. If I had to state a winner when regarding performance and features as well as overall value for money, the OnePlus 12 would be the winner. It has a comprehensive camera, a longer battery time, and that crazy 100W charge is just icing on the cake. Plus, its OxygenOS tends to feel snappier and more user-friendly than Xiaomi’s MIUI.
