Verdict on the OnePlus 15T
The OnePlus 15T smartphone looks stylish, feels high-quality, and leaves a strong impression in everyday use. Thanks to a great ultrasonic sensor, a high-end chipset that is beyond reproach and a really beautiful OLED panel, the mini flagship from OnePlus makes the hearts of fans of compact smartphones beat faster.
The battery run times are also phenomenally good for this handy form factor.
Are there possible deal breakers with the OnePlus 15T? Unfortunately, yes. Due to lack of availability outside of China, certain limitations have to be accepted with the software — such as eSIM or WearOS support — although ColorOS with its multi-language package and Google integration is also quite easy to use in Europe unlike Xiaomi phones from the Far East.
The OnePlus phone cannot deny its origins when it comes to cellular frequency support either.
However, the disadvantages of importing the OnePlus 15T are sweetened by the low price. For less than €600, the overall package is really good for the compact class and therefore an interesting alternative to a Galaxy S26 or Pixel 10 Pro.
Pros
Cons
Price and availability of the OnePlus 15T
The OnePlus 15T has so far been launched exclusively for the Chinese market at an RRP of ¥4,300 or around €550. As an import from Trading Shenzhen, prices start at around €570. A global launch currently seems unlikely.

Specifications of the OnePlus 15T
Build and features: Handy Android phone with IP69 and thin edges
OnePlus relies on the same design as the flagship 15 for its 15T model. Thanks to the metal frame and glass back, the housing, which is water-resistant to IP69, feels premium in the hands.
The dimensions and weight are similar to an Apple iPhone 17, but the OnePlus 15T sports more than twice the battery capacity. It is all the more impressive that OnePlus has managed to make the display edges super-thin, with a screen-to-body ratio of nearly 91%.
In contrast to the OnePlus 15, the T model only has one USB 2.0 port. Otherwise, the compact Android phone is very well equipped with NFC, infrared port, and dual-band GNSS as well as UFS 4.1 flash and LPDDR5X Ultra RAM.
Communication and operation: OnePlus 15T with Wi-Fi 7 and ultrasonic fingerprint sensor
In addition to Bluetooth 6.0, the OnePlus 15T also supports the modern Wi-Fi 7 standard. Transmission speeds including in the 6 GHz channel are high, but the consistency is only average.
The compact Android phone shows weaknesses for use in Europe when it comes to LTE frequencies. Neither band 20 nor band 32 can be used with the OnePlus 15T.
In the 5G network, however, there are no restrictions for German-speaking countries.
When it comes to operation, the strengths of the little brother of the OnePlus 15 come to the fore. The touchscreen feels very responsive and fast.
Thanks to an ultrasonic finger pressure sensor, the compact OnePlus phone unlocks very quickly and reliably. The vibration motor (X-axis) also provides high-quality haptic feedback.

Software and sustainability: OnePlus gives Android 16 for its top-of-the-range phone
ColorOS comes pre-installed on the OnePlus 15T instead of the global OxygenOS. However, the differences are rather minor overall. German language and Android Auto are supported, but WearOS watches or eSIMs are not supported.
There are question marks over the duration of the updates provided. The manufacturer does not usually provide any information on this for China. Typically, a OnePlus 15 should receive security updates for six years.
As the OnePlus 15T is not officially coming to Europe, repairability is significantly limited and, as is usual for Chinese devices, we cannot find out any information on the CO2 footprint or details of the recycled materials contained.
Cameras: OnePlus 15T offers telephoto and OIS
The compactness and price range of the OnePlus 15T have the most negative impact on the camera system. The cooperation with Hasselblad is now Oppo-exclusive and OnePlus' built-in image sensors are quite small and therefore not very bright.
The 50 MP main camera only comes with a 1/1.56-inch sensor, although good photos are possible in daylight as well as in the dark but top quality looks different. It lacks sharpness and dynamics. As our comparison photos show, the compact smartphone from OnePlus is still a class above the handy iPhone 17 from Apple.
The OnePlus 15T does not have an ultra-wide-angle camera, but it can zoom 3.5x optically thanks to the 50 MP telephoto lens.
Since the main camera takes relatively wide-angle photos at 24 mm, the addition of a telephoto lens with OIS makes much more sense in our opinion.
Display: OnePlus 15T with a 165 Hz OLED panel
The 6.32-inch 165 Hz AMOLED panel achieves a very good pixel density of 460 ppi with a resolution of 1,216 pixels. We achieved the advertised maximum brightness of 1,800 nits fairly accurately in our APL18 measurement.
However, the measured values for the HDR peak brightness (3,600 nits) are a good deal lower, but 3,125 cd/m² is also easily sufficient for good HDR effects.
OnePlus advertises an extremely high-frequency PWM dimming (3,840 Hz) below 70 cd/m² to control the brightness.
At higher brightness levels, the 15T switches to a DC-like dimming mode. We measured a base frequency of only 120 Hz and an amplitude of 18 percent — neither of which are optimal values for PWM-sensitive people, despite the high-frequency dimming modes.

Performance, emissions, and battery life: Compact Android smartphone with large battery and high-end SoC
There is no need to compromise on the chipset with the compact Android phone. The OnePlus 15T uses a powerful Snapdragon 8 Elite Gen 5 that, thanks to its Adreno 840, achieves very high scores not only in the CPU benchmarks but also in the graphics benchmarks.
In the 3DMark stress tests, however, the OnePlus 15T shows a sharp drop in performance of over 50%, which significantly lowers our rating.
OnePlus relies on a silicon-carbon-based battery with a large capacity of 7,500 mAh for its mini flagship smartphones. The energy storage can be charged with a maximum of 100 W or 50 W wirelessly. In our practical battery test with an adjusted display brightness of 150 cd/m², the OnePlus 15T achieved an excellent battery life of nearly 1.5 days.
