Xiaomi 15T Professional Assessment

In my view, the T sequence from Xiaomi has been persistently probably the greatest telephones of the 12 months, offering patrons with an virtually flagship expertise with out the related premium value.

The one different competing mannequin I can consider is the Honor x00 Professional sequence, with the 200 Professional launching at a cheaper price level than the Xiaomi 14T Professional. However the Honor 400 Professional, which launched again in Might, launched at a better value level of £700.

Xiaomi has now launched its newest T mannequin, the Xiaomi 15T Professional, which I’ve been utilizing for the previous few weeks.

Associated Critiques

Specification

Unboxing / Design

The Xiaomi 15T Professional incorporates a unified glass fibre again and battery cowl, offering a single-piece really feel. I used to be despatched the 15T Professional in Black, which is a bit boring, however seems to be good; it is usually accessible in Gray and Mocha Gold, with a refined flat-frame aesthetic that’s noticeably slimmer than older fashions at 7.96mm, weighing in at a smart 210g (1g heavier than its predecessor).

The telephone additionally has an IP68 score with 3-metre freshwater immersion, which is nice and one thing I all the time discovered vital in a telephone as a result of inclement UK climate, however the actuality is that I haven’t had a telephone die as a result of water ingress because the Google Nexus 6P.

The aluminium alloy body is meant so as to add further drop resistance, paired with Corning Gorilla Glass 7i for double the scratch resistance, a welcome shift in comparison with typical mid-range flagships that lack this grade of safety.

At 6.83 inches, that is the biggest show Xiaomi has ever put in a T-series telephone. The 1.5K decision (2772 x 1280) delivers 447 ppi, which is sharp sufficient for many makes use of. The 144Hz refresh fee and 480Hz contact sampling ought to make interactions really feel fluid, although I query whether or not most customers can genuinely profit from refresh charges above 120Hz.

The 3200-nit peak brightness is spectacular, albeit a downgrade from the 4000 nits on the earlier mannequin, however that’s brighter than many premium telephones such because the Pixel 10 Professional XL and will imply glorious outside visibility.

The 1.5mm bezels are genuinely slim and create a extra immersive viewing expertise, although some could discover this will increase mistouches.

Notable consolation options are inbuilt too, together with DC dimming, flicker-free certification, and TV Rheinland low blue mild accreditation, which I discovered is more and more vital throughout longer session utilization. HDR10 and Dolby Imaginative and prescient assist spherical out the visible expertise, positioning the show near the highest finish of what’s on provide at this value level.

Digicam

Xiaomi continues its partnership with Leica, delivering a triple digicam array that includes a 50MP predominant sensor with a Summilux lens, a 12MP ultra-wide with a 120-degree area of view. Then there’s a a 50MP 5x optical telephoto able to as much as 10x optical-level zoom, which is an enormous improve from the two.6x optical zoom on the earlier mannequin.

The primary digicam makes use of a big f/1.62 aperture and OIS, designed to tug in additional mild for improved readability and dynamic vary. The press launch doesn’t point out the sensor dimension, however does state that it’s a Mild Fusion 900 picture sensor, and the specs seem like equivalent to the Xiaomi 15 and 14T Professional, so it’s going to seemingly be a 1/1.31″ sensor.

The telephoto lens presents detailed photographs of distant topics, splendid for wildlife or occasions, whereas the vast lens is tuned for expansive group scenes or structure.

There’s additionally a front-facing 32MP sensor offering a large 90-degree area for group selfies. The suite of capturing modes consists of superior bokeh results, customisable portrait settings, and Leica avenue pictures mode, which permits on the spot seize from the lock display, a function which may enchantment to anybody involved about quick-shoot situations.

The 12MP ultrawide is likely one of the few giveaways that this isn’t a flagship telephone. It takes sufficient photographs, however I might solely use it when completely needed.

Video capabilities have been significantly stepped up, too. 8K at 30fps is supported, in addition to a number of 4K choices, together with 120fps and professional-grade 10-bit Log recording for editors who need extra color flexibility. HDR10 recording is offered throughout focal lengths, so content material creation expectations are real looking: this can be a machine constructed for individuals who really want these options at a top quality above primary smartphone shooters.

Efficiency

The Xiaomi 15T Professional continues to be powered by MediaTek’s flagship chipset, this 12 months it’s the Dimensity 9400 chipset constructed with a 3nm course of. The telephone guarantees a wholesome step up in each CPU and graphics efficiency over its predecessor.

It’s accessible with 12GB RAM and storage variants overlaying 256GB, 512GB and even 1TB. LPDDR5X reminiscence and UFS 4.1 storage are current, which, first-hand, I can affirm, present noticeably snappier app launches and knowledge transfers.

Xiaomi’s 3D IceLoop cooling system is supposed to deal with thermal considerations, however in my expertise, these advertising and marketing phrases typically don’t translate to dramatically higher real-world thermal administration. Nevertheless, any enchancment in thermals is welcome, regardless of how small it’s.

Benchmarks

Just like my earlier Xiaomi opinions, I haven’t had a lot luck operating in style benchmarks. As common, I’m unable to obtain the information required to run any of the 3Dmark benchmarks, and this 12 months I’m unable to get Antutu to show outcomes, with it stating it received’t present the consequence except it’s verified on-line. The telephone had Web, so the add will need to have been blocked, that is presumably as a result of it’s unreleased on the time of testing, or maybe a block by Xiaomi.  

That being mentioned, Geekbench reported some spectacular outcomes with 2690 for a single core and 8300 for multi-core, which isn’t removed from the Xiaomi 15T, which has the flagship Qualcomm chipset for 2025

• Geekbench 6
  • Xiaomi 15T Professional: 2690 / 8300
  • Xiaomi 15: 3052 / 9335
  • Xiaomi 14T Professional: 2182 / 7205
  • Pixel 9 Professional XL: 1917 / 4600
  • Pixel 8 Professional: 1763 /  4409
  • Samsung Galaxy S24 Extremely: 2103 / 6640
  • Honor Magic6 Professional: 2220 / 6897

Connectivity

5G, Wi-Fi 7, NFC, and Bluetooth 6.0 (an improve from 5.4) are all included, overlaying trendy community expectations for 2025. The machine helps twin SIM, together with eSIM choices, and boasts Xiaomi’s Astral Communication options, which now add offline device-to-device voice calls with a spread of as much as 1.9km between handsets, impartial of the community, probably helpful for area of interest situations like climbing or festivals.

Battery Life / Charging

Battery capability is quoted at 5500mAh, supporting each 90W wired HyperCharge and 50W wi-fi charging.

The wired charging is definitely a downgrade from the 120W that was succesful on the 14T Professional, however I believe the ten% improve in battery capability makes up for this downgrade.

Like most trendy telephones, there isn’t a bundled charger and you’ll seemingly want to purchase a Xiaomi HyperCharger to benefit from it.

Wi-fi charging speeds are excessive, though you’ll have to finances for Xiaomi’s personal charger or a appropriate Qi equal.

Battery life is said as as much as simply over fifteen hours of fixed use, which, on spec, seems to be aggressive towards most present flagships.

Android OS / Xiaomi HyperOS 3

The telephone is shipped with Xiaomi HyperOS 3, which is predicated on Android 15.

The telephone will get widget, lock display and notification upgrades, together with improved multitasking and faster app transitions.

Xiaomi HyperAI options are additionally energetic, geared toward bettering productiveness, although the specifics range by area. The UI aligns carefully with the aesthetic modifications most will discover as recent, fairly than revolutionary.

Whereas I don’t thoughts Xiaomi HyperOS, I might say it’s my least favorite of the varied Android skins. Maybe as a result of I’ve extra expertise with it, however I might give Honor MagicOS a slight edge over HyperOS, and naturally, the inventory Pixel Android OS is arguably the most effective (by a snug margin).

Worth / Alternate options

On the time of writing, I’ve not been offered the official value. Nevertheless, it has not too long ago been leaked that the telephone will launch with a beginning value of €899 (round £785), which incorporates 512 GB of storage and 12 GB of RAM. An earlier leak indicated it could be €799 (round £700) for the 256GB mannequin.

Some folks have instructed this can be a value hike, however my overview of the Xiaomi 14T Professional, which launched at €799 as properly. Going additional again, the Xiaomi Mi 10T Professional had an RRP of £600, so I don’t really feel like the value has elevated excessively over time.

Xiaomi didn’t launch the 15 Professional in Western markets, and the 15 is a a lot smaller telephone, so there isn’t a clear step up from the 15T Professional. In case you needed a very flagship expertise, you’d have to get the £1300 Xiaomi 15 Extremely.

As beforehand said, the Honor 400 Professional is probably going the most effective various possibility. This has an RRP of £700 for 12GB RAM and 512GB storage, however is at present discounted to £540 on Amazon. This makes use of the Qualcomm Snapdragon 8 Gen 3 (4 nm), which scores fairly a bit decrease on Geekbench, however I’m unable to check with different in style assessments, particularly gaming.

OnePlus is like the opposite finest various. The OnePlus 13 is nearly a 12 months outdated now,, which suggests you may choose it up with a little bit of a reduction, priced at £789  (£999 RRP) and has principally higher specs throughout, together with 16GB RAM and 512GB storage.

Or, the OnePlus 13R, which launched in January, is offered for £527, which makes use of the identical Snapdragon 8 Gen 3  chipset because the Honor 400 Professional. The digicam spec is just not fairly pretty much as good because the others, and it has a decrease IP score, however you may’t actually criticise it an excessive amount of as a result of enticing pricing.

In case you had been to take a look at Google and its Pixel telephones, the closest in value is the Pixel 10 at £799, which has inferior {hardware} throughout (although the software program expertise goes some solution to make up for its shortcomings).

Total

The Xiaomi 15T Professional is one other implausible telephone from Xiaomi, and possibly my favorite mannequin of their vary as a result of comparatively enticing pricing, however just a few compromises on flagship options.

Like most trendy telephone launches, there may be solely an incremental improve from the earlier era. You’ve gotten the standard chipset improve, then the telephoto lens has a formidable improve, a bigger (however much less shiny) show, and a bigger (however slower-charging) battery. So, it wouldn’t be value upgrading from the 14T Professional.

Nevertheless, there are only a few different telephones that compete with this at this value level, and I’m nonetheless adamant that that is the most effective value level for Android telephones. Each this and the Honor 400 Professional are wonderful telephones at affordable costs, then the OnePlus 13 at a better value however higher specs, or the OnePlus 13R if you wish to keep beneath £600.
