Xiaomi 15T review

6. Final words, our verdict, pros and cons

The competition

The Xiaomi 15T launched with an official MSRP of €649, but just a couple of weeks after release, it can already be found for around €480 - €500 at online stores across Europe. Or if you are paying full price, Xiaomi usually throws in some bonus (like a free tablet in Spain).

This pricing puts 15T in a very competitive segment, rubbing shoulders with both premium mid-rangers and slightly discounted flagships from late 2024 and early 2025. With its Leica-branded triple-camera setup, premium design, IP68 rating, and bright 120Hz AMOLED display, the 15T aims to bring many flagship traits to a more attainable price - but the competition in this price range is intense.

The most obvious rival comes from inside the family - last year's Xiaomi 14T Pro. It costs roughly the same today, yet it features the more powerful Dimensity 9300+ chipset, which yields higher benchmark scores. It also adds faster 120 W wired charging and wireless charging, features the 15T omits. Its main camera has a slightly larger sensor, and the build quality benefits from an aluminum frame instead of a plastic one. Still, the 15T fights back with a larger 6.83-inch panel, a bigger 5,500 mAh battery, and a slimmer, lighter chassis. For users who value comfort, endurance, and thermal efficiency over raw horsepower, the 15T might be the more balanced pick - especially since display brightness and color quality are effectively on par.

Xiaomi 14T Pro • Samsung Galaxy S25 FE • Xiaomi Poco F7 • OnePlus Nord 5

The Samsung Galaxy S25 FE is another major rival and perhaps the most balanced alternative from outside Xiaomi’s ecosystem. Priced around €550, it sits slightly above the 15T but justifies that premium with longer software support — seven years of major Android updates — and a more polished ecosystem. The Exynos 2400 chip performs on par with the Dimensity 8400 Ultra in day-to-day use and even pulls slightly ahead in GPU-bound tasks, while the LTPO Dynamic AMOLED 2X display offers variable refresh down to 1 Hz for better efficiency. The S25 FE also supports Qi2 wireless charging, reverse charging, and faster 45 W wired speeds, all features missing on the 15T. However, Xiaomi counters with a larger 5,500 mAh battery, a brighter and sharper screen, and Leica-tuned cameras that deliver richer photo and video output, especially in HDR. The Galaxy has better quality materials, such as an aluminum frame and Gorilla Glass Victus+ panels on both sides, but the 15T arguably offers more value for the money with higher endurance, faster charging, and a more premium multimedia experience overall.

From Xiaomi's own stable, the Poco F7 is the performance-focused alternative. For about €365, it undercuts the 15T significantly while offering a Snapdragon 8s Gen 4 chip that actually outperforms the Dimensity 8400 Ultra in synthetic benchmarks. It also has a much larger 6,500 mAh battery and 90W fast charging. The trade-offs include the simpler dual-camera setup, a heavier build, and the absence of Leica tuning or flagship-grade imaging features. If you're primarily concerned with gaming power and battery longevity, the Poco F7 is the better value due to its lower retail price.

Finally, the OnePlus Nord 5 sits close in both price and positioning. It costs around €459 and packs the Snapdragon 8s Gen 3, which lags slightly behind Xiaomi's Dimensity 8400 Ultra but still ensures flagship-level responsiveness. The Nord 5's 5200mAh battery in Europe didn't score so hot in battery life but the phone is available with a 6800 mAh battery elsewhere making it a true endurance champ, and its lighter OxygenOS skin will appeal to those preferring a cleaner software experience. Still, the 15T offers a more refined camera setup with a telephoto lens, improved HDR video capture, IP68 water resistance (versus IP65), and a brighter, higher-quality display panel.

Overall, the Xiaomi 15T manages to hold its ground in this crowded mid-flagship field. It's not the outright performance leader, nor the fastest to charge, but it offers one of the most balanced packages around - combining a large and premium display, versatile Leica-tuned cameras, flagship-grade waterproofing, and solid battery life at a fair post-launch price.

Our verdict

The Xiaomi 15T stays true to the T-series mission - to deliver an experience that comes impressively close to Xiaomi's true flagships while keeping the price in check. It's a phone that feels premium through and through, without trying to overreach.

We came away quite impressed with how cohesive and well-rounded the package feels. The design may be understated, but the build quality is excellent. The IP68 rating (now rated for up to 3m submersion) adds real peace of mind, and despite the plastic mid-frame, the handset feels rigid and pleasant to the touch.

The large 6.83-inch AMOLED display is a highlight - bright and smooth at 120 Hz. It's easily flagship-grade in all but the refresh-rate flexibility, which remains LTPS-based. Still, visibility outdoors is superb thanks to the 1500+ nit measured brightness.

Performance is another area where the 15T holds its ground. The Dimensity 8400 Ultra delivers more than enough power for everyday use and gaming, and Xiaomi's IceLoop cooling system maintains sustained performance. Paired with LPDDR5X RAM and UFS 4.1 storage, the phone feels fast, fluid, and future-proof enough for its class.

Battery life is also solid - a 5,500 mAh cell that comfortably lasts a full day and beyond. The 67 W charging isn't class-leading anymore, but it's consistent and safe, refilling the battery in just over 50 minutes.

Xiaomi's latest HyperOS 2, built on top of Android 15, feels mature and fast, with six years of security coverage and four major OS upgrades promised. The interface remains rich in features, and the new AI suite and Google Gemini integration make it feel modern and flexible.

The triple Leica-tuned camera setup performs very well for the class. The main 50MP sensor excels in daylight and performs well in low light as well. The 2x telephoto produces sharp, natural-looking shots, while the ultrawide camera is decent even if it's unsurprisingly behind the other two. Video capture is excellent at 4K@60 HDR10+, with reliable stabilization. The 32 MP selfie camera also delivers detailed and nicely toned results, though the fixed focus can sometimes miss ideal sharpness.

So, where does it fall short? The frame and back are made of plastic, and wireless charging is notably absent, especially given that cheaper rivals are now starting to include it. Charging speeds, while good, are no longer chart-topping. The 2x zoom camera lacks OIS, the ultrawide camera could use autofocus, and the software proximity sensor remains a bit of a compromise. A true stereo balance and slightly more vivid mid-range in the speakers would have been nice too.

But honestly, that's nitpicking. The Xiaomi 15T delivers a polished, powerful, and dependable experience that covers all the important bases and falls short. If you can live without wireless charging and the fastest charging speeds, you'll find the Xiaomi 15T to be one of the most balanced and feature-complete smartphones in its price segment. It's easy to recommend and absolutely deserves a place on your shortlist.
