What Makes the Xiaomi 12 Worth Buying?

The Xiaomi 12 delivers flagship performance in a surprisingly compact package. At just 152.7mm tall and weighing under 180g, it’s one of the most pocket-friendly premium phones available. The Snapdragon 8 Gen 1 processor ensures snappy performance whether you’re gaming, multitasking, or editing photos.

The display stands out with its 120Hz AMOLED panel that peaks at 1100 nits, making outdoor visibility excellent even in direct sunlight. Dolby Vision and HDR10+ support means streaming content looks stunning with vibrant colors and deep contrasts. The phone charges remarkably fast too—67W wired charging fills the 4500mAh battery completely in just 39 minutes, while 50W wireless charging gets you to 100% in 53 minutes.

Build quality doesn’t disappoint either. Gorilla Glass Victus protects the front, Gorilla Glass 5 guards the back, and an aluminum frame holds everything together. The 50MP main camera with optical image stabilization captures sharp photos even in challenging lighting, and the ability to shoot 8K video gives content creators professional-grade flexibility.

Things to Know Before Choosing the Xiaomi 12

Storage options are fixed—there’s no microSD card slot for expansion. You’ll need to choose wisely between the 128GB or 256GB variants based on how many photos, videos, and apps you typically store. Heavy users who download lots of games or shoot extensive 4K/8K footage might find the base storage limiting.

The 4500mAh battery capacity is decent but not exceptional by 2024 standards. With the power-hungry Snapdragon 8 Gen 1 and high-refresh display, you’ll likely need to charge daily with moderate to heavy use. The phone does get warm during extended gaming sessions or when recording 8K video, which is common for this generation of Snapdragon processors.

MIUI 13 based on Android 12 comes with extensive customization options, but it also includes pre-installed apps that some users find unnecessary. The interface takes time to learn if you’re switching from stock Android. The lack of a headphone jack means you’ll need USB-C or wireless earbuds—something to consider if you prefer wired audio gear.

NFC availability varies by market, so confirm this feature is included in your region if you rely on contactless payments. The 5MP telephoto macro camera is specialized for extreme close-ups rather than traditional zoom photography, which might not suit everyone’s shooting style.

Is the Xiaomi 12 Right for You?

Mobile Gamers will appreciate the smooth 120Hz display and powerful Adreno 730 GPU. The stereo speakers tuned by Harman Kardon deliver immersive audio, though you’ll want to manage your expectations for extended gaming sessions due to thermal considerations.

Photography Enthusiasts get a versatile triple camera setup with the main 50MP sensor handling most scenarios beautifully. The optical stabilization helps with low-light shots and video recording. The 13MP ultrawide captures expansive scenes, while the 5MP macro lens opens creative possibilities for extreme close-up photography.

Content Creators can shoot professional-quality footage with 8K recording at 24fps or 4K at up to 60fps with HDR10+. The front-facing 32MP camera delivers crisp selfies and supports 1080p video at 60fps for vlogging. Gyro-EIS keeps footage stable even when shooting handheld.

Compact Phone Seekers will love the manageable size. It fits comfortably in one hand and slips easily into pockets, something rare among flagship devices. Despite the smaller footprint, you’re not sacrificing screen real estate—the 6.28-inch display offers plenty of space for productivity and entertainment.

Busy Professionals benefit from the rapid charging speeds. A quick 20-minute charge can provide several hours of use, perfect when you’re rushing between meetings. The reverse wireless charging lets you top up wireless earbuds or a smartwatch in a pinch.

Budget-Conscious Buyers might want to wait for price drops or consider whether flagship specs are necessary for their daily use. The phone launched at premium pricing, though deals become more common as newer models release.

Best Alternatives to the Xiaomi 12

The Samsung Galaxy S22 offers similar compact dimensions with comparable specs, longer software support, and a more refined camera experience. Samsung’s One UI provides a cleaner interface than MIUI for those who prefer less aggressive customization.

OnePlus 10 Pro delivers comparable performance with a larger battery and faster 80W charging. The OxygenOS experience sits closer to stock Android, though the phone itself is noticeably larger.

iPhone 13 presents an alternative for those in Apple’s ecosystem. You’ll get superior video recording, longer battery life, and extended software updates, though at a higher price point and without the flexibility of Android.

Realme GT 2 Pro provides similar Snapdragon 8 Gen 1 performance at a lower price. You’ll sacrifice some build quality and camera refinement, but it’s worth considering if budget is the primary concern.

Xiaomi 12 Frequently Asked Questions

Does the Xiaomi 12 support expandable storage?

No, the Xiaomi 12 does not include a microSD card slot. You’ll need to choose between the available internal storage options of 128GB or 256GB at purchase. Cloud storage services can supplement your space if you need additional room for photos and videos.

How long does the battery last on a full charge?

Battery life varies based on usage patterns, but expect a full day with moderate use. The 4500mAh capacity combined with the efficient 4nm Snapdragon 8 Gen 1 processor provides roughly 6-8 hours of screen-on time. Heavy gaming or 8K video recording will drain the battery faster, though the 67W fast charging quickly tops you up.

Can the Xiaomi 12 record in 8K resolution?

Yes, the main 50MP rear camera supports 8K video recording at 24fps with HDR. You can also shoot 4K video at 30fps or 60fps with HDR10+ support. The front camera maxes out at 1080p resolution at 60fps, which is still excellent for selfie videos and video calls.

Is the Xiaomi 12 waterproof?

The specifications don’t mention an official IP rating for water resistance. While the phone features quality build materials including Gorilla Glass protection front and back, it’s best to avoid exposing it to water or moisture. Consider a protective case if you frequently use your phone in wet environments.

Does the phone come with a charger in the box?

Box contents vary by region and purchase time. Many markets included the 67W fast charger with the phone at launch, but packaging policies have evolved. Check with your retailer or the product listing to confirm what accessories are included with your specific purchase.
