Xiaomi 15T Pro review: A “flagship killer” that’s priced like a flagship

Xiaomi’s new 15T lineup has arrived. This series is traditionally supposed to be the “slightly cut-down but still powerful” alternative to Xiaomi’s true flagships — and this year we get two models: the regular Xiaomi 15T and the higher-end Xiaomi 15T Pro.

We’re focusing on the Pro version, because on paper it absolutely earns that label. You’re getting:

• a huge 6.83-inch display running at 144Hz, capable of hitting 3,200 nits peak brightness,
• a 5x periscope telephoto camera,
• and a 5,500 mAh battery with support for 90W fast charging.

All of that sounds impressive… but there’s a catch.
The Xiaomi 15T Pro also arrives with premium pricing. The base model with 12GB RAM and 256GB storage starts at €799 (which is over $900 USD). At that price, you’re directly competing with “real” flagships from Google, Samsung, and Apple. So calling it “affordable” doesn’t really work anymore.

Still, this phone is interesting. It absolutely dominates in a couple of key areas (including battery life), so let’s dig in.

Xiaomi 15T Pro — Highlights

What’s great

• Excellent, super-bright 144Hz display
• Outstanding battery life
• Strong long-range telephoto camera

What’s not great

• Expensive for what the “T” series used to be
• Chipset doesn’t always match top Snapdragon numbers in synthetic tests
• Only 4 years of major Android updates promised

Overall rating: 7.6 / 10
That’s slightly above the average for phones in this price tier, which also includes devices like the Motorola Edge 60 Pro, Pixel 10, and OPPO Find X8 Pro.

Specs

Premium hardware… and premium price

Before anything else, here’s the basic profile of the Xiaomi 15T Pro:

• Dimensity 9400+ processor
• Up to 1TB storage
• 5,500 mAh battery with 90W wired / 50W wireless charging
• Triple rear camera system with 5x optical zoom
• 6.83″ 144Hz AMOLED panel, 3,200-nit peak brightness

So yeah, it’s loaded.

Design and Display

Blinding brightness and a very grown-up build

Visually, the Xiaomi 15T Pro follows the general direction of the main Xiaomi 15 series (and before that, the 14T), but there are tweaks. The camera block is still a square, but the edges are beveled and softened, and the camera island matches the phone’s body color. It’s cleaner and looks more intentional than just “stuck on top.”

The frame uses a 6M13 aluminum alloy — a hardened aluminum blend with magnesium, silicon, copper, manganese, iron, zinc, chromium, and titanium. In the hand it still feels like aluminum, not steel or titanium, but it’s meant to be tougher.

On the back, Xiaomi is using glass fiber, and the screen on the front is protected by Gorilla Glass 7i. The phone is physically big — that 6.83-inch panel demands it — and it’s not light. It’s over 200 grams, so you definitely feel it in the hand.

Color options:

• Black
• Gray
• Mocha Gold (the standout one, which has a bronze-like finish)

Build quality is genuinely premium, which it should be at this price.

One note we don’t love: Xiaomi seems to be following the rest of the industry toward “eco packaging.” Unlike older Xiaomi flagships that came with a full retail kit, the 15T Pro box doesn’t include a charger. You still get a pre-applied screen protector, a silicone case, and a USB-C cable, but to take advantage of the 90W fast charging, you’ll need to buy the charger separately.

Display

Now for the good part.

The Xiaomi 15T Pro’s screen is a 6.83-inch AMOLED with:

• 144Hz refresh rate,
• 2772 x 1280 resolution (~477 ppi),
• and a claimed 3,200-nit peak brightness.

We measured it at just over 3,190 nits in 20% APL tests, which is insanely bright. It actually beats the regular Xiaomi 15 in those conditions and ranks among the brightest displays we’ve ever tested. In direct sunlight, this thing is extremely readable — not just “okay,” but “wow.”

Minimum brightness, around 2 nits, isn’t the absolute lowest we’ve seen for night use, but still usable.

The under-display fingerprint reader is optical (not ultrasonic like on some higher-end Xiaomi models), but it works reliably enough. There’s also face unlock, though it’s just camera-based, so it’s less secure.

Verdict on hardware and screen:

• Build: premium, big, and a little heavy
• Display: fantastic — sharp, fast, and incredibly bright
• Ergonomics: not for small hands

Camera

Especially impressive at 5x zoom

The Xiaomi 15T Pro uses a triple-camera setup:

• 50MP main camera (same main sensor as the Xiaomi 15), 1/1.31″ sensor, f/1.6 lens, OIS, PDAF
• 50MP periscope telephoto with 5x optical zoom (115mm equivalent, f/3.0)
• 12MP ultrawide

The main camera delivers exactly what you’d expect at this level: solid exposure, good detail, and wide dynamic range. Colors look natural instead of overly punched-up.

The ultrawide is fine, but clearly weaker than the main shooter. You start to lose detail, especially in low light, and shadow handling isn’t as strong. Dynamic range narrows. This is the one part of the camera setup that feels more “midrange.”

The surprise win is the 5x periscope telephoto. It’s legitimately good — sharp, stable, and completely usable for portraits as well as distant detail. Image quality from that 5x lens is much closer to the main camera’s standard than we usually see at this price (or even higher).

Yes, you can crop the main sensor for a 2x shot, but the 5x periscope is where this phone feels special.

Video

Video capture supports a wide range of formats:

• Up to 8K at 30fps
• 4K at 120fps
  We found 4K at 60fps to be the sweet spot for stabilization vs clarity.

So, overall camera takeaways:

• Main camera: strong and reliable
• Ultrawide: decent but clearly a step down
• Telephoto: excellent, one of the best reasons to buy this phone

Performance

Fast in real use, but not a benchmark monster

Inside the Xiaomi 15T Pro is the MediaTek Dimensity 9400+. It’s an octa-core chip designed to go toe-to-toe with Snapdragon 8 Elite. You also get 12GB of RAM by default, and storage options up to 1TB.

In day-to-day use, the phone feels smooth and responsive. Apps open quickly, animations are snappy, and multitasking isn’t a struggle. But when we stress-tested it, the story got more complicated.

In CPU benchmarks like Geekbench, and in GPU stress tests like 3DMark, the Dimensity 9400+ can spike high at first — even close to Snapdragon 8 Elite territory — but it tends to heat up and then throttle down. Sustained performance drops off once the phone starts running hot.

In other words:

• Burst performance: very good
• Sustained heavy load: not as good as the latest Snapdragon flagships
• Thermal control: could be better

It’s still fast, but it’s not the undisputed performance king.

Software

HyperOS 2.0, with AI seasoning

The Xiaomi 15T Pro ships with HyperOS 2.0 on top of Android 15. The overall experience feels almost identical to Xiaomi’s true flagships — clean visuals, some customization flexibility, not a ton of bloat.

AI features are sprinkled in: AI writing helpers, AI editing tools in the gallery, live translation / interpreter features, and Gemini access via the power button. Xiaomi is clearly pushing its own AI layer, but it’s also leaning on Google’s ecosystem.

Software support:

• 4 years of major OS updates
• 6 years of security patches

That’s… acceptable, but not amazing for this price bracket in 2025. Samsung is doing six years of OS updates on some cheaper lines, and Google is now promising seven years of support on certain mid-priced Pixels. Xiaomi is behind there.

Battery

This is where the phone absolutely destroys most rivals

Here’s the headline: the Xiaomi 15T Pro is a battery monster.

With its 5,500 mAh battery and the Dimensity 9400+ on a 3nm process, the phone posted incredible endurance numbers in testing:

• Overall battery score around 9h 37m screen-on equivalent, which ranks near the very top of anything we’ve tested in the last couple of years.
• Web browsing time of nearly 25 hours straight.
• Video playback and gaming times that are also way above average.

In normal use, this is realistically a two-day phone for most people.

Charging:

• Up to 90W wired (but you’ll need to buy the charger separately)
• Up to 50W wireless, using Xiaomi’s proprietary high-speed wireless chargers
• Full charge in about 40 minutes over wired fast charging

Even with the slight downgrade from last year’s 120W wired charging on the 14T Pro, the 15T Pro still charges dramatically faster than almost all mainstream phones from Samsung or Apple.

Battery summary:

• Elite stamina
• Very fast top-ups
• Real-world “don’t worry about it” energy

This is one of the main selling points.

Audio and Haptics

Audio comes from a stereo setup (earpiece + bottom speaker). It gets loud enough that you won’t miss calls or alerts. At maximum volume there’s some harshness in the treble — that “hissy” edge in high frequencies — so for long movie sessions, headphones are better.

Haptics are solid: strong, reasonably tight, and not mushy.

Should you buy the Xiaomi 15T Pro?

Here’s where it gets complicated.

The “T” series used to be the smart buy — almost flagship performance for noticeably less money. But that gap has been closing for a couple of generations, and now the Xiaomi 15T Pro starts at €799. That’s flagship territory. Yes, it’s still cheaper than a €999 Xiaomi 15, but it’s more expensive than phones like the Pixel 10, Galaxy S25, or iPhone 17 base model.

So is it worth it?

Why you’d want it:

• One of the brightest, smoothest displays on any phone right now
• Incredible battery life — genuinely class-leading
• A versatile camera setup with a shockingly good 5x periscope lens
• Fast wired and wireless charging

Why you might skip it:

• It’s no longer “budget flagship” pricing
• The Dimensity chip runs hot and can’t keep peak performance for long
• Software support (4 OS versions) lags behind what Google and Samsung now promise
• No charger in the box, even at this cost

Final take:
The Xiaomi 15T Pro absolutely delivers in display quality, zoom camera, and battery life. Those parts feel top tier. The problem is that at €799+, those strengths aren’t exciting “for the price” anymore — they’re just what we expect from anything this expensive.
