Security and usability features include an under-display optical fingerprint sensor, accelerometer, gyro, proximity, compass, and Circle to Search.

For connectivity, Xiaomi 15T offers USB Type-C 2.0 with OTG, an infrared port, NFC (region-dependent), and a wide array of positioning systems: GPS (L1+L5), BDS, GALILEO, QZSS, NavIC, and GLONASS. Wireless options include Wi-Fi 6e with dual-band and Wi-Fi Direct, plus Bluetooth 6.0.

Audio is handled by stereo speakers with Dolby Atmos, alongside 24-bit/192kHz Hi-Res wired and wireless audio support, though it lacks a 3.5mm headphone jack. On the camera front, the device sports a triple rear setup with Leica lenses: a 50MP wide sensor with OIS, a 50MP telephoto lens (2x optical zoom), and a 12MP ultrawide camera (120° FOV).

Photography is enhanced with Ultra HDR, HDR, panorama, color spectrum sensor, and LED flash. Video recording supports 4K@30/60fps, 1080p up to 960fps, with gyro-EIS, HDR10+, and 10-bit Rec.2020. The 32MP front camera records 4K@30fps and 1080p@30/60fps, with HDR and HDR10+ support.

Performance is powered by the MediaTek Dimensity 8400 Ultra (4nm) chipset, featuring an octa-core CPU and Mali-G720 MC7 GPU. It runs on Android 15 with HyperOS 2. Memory options include 256GB or 512GB UFS 4.1 storage with 12GB RAM, though there’s no card slot.

The 6.83-inch AMOLED display offers 68B colors, HDR10+, Dolby Vision, 3840Hz PWM, 120Hz refresh rate, and 3200 nits peak brightness, protected by Corning Gorilla Glass 7i (Mohs level 6). The device measures 163.2 x 78 x 7.5 mm, weighs 194g, and is IP68 water and dust resistant.

Display Colors Display Colors is refers to the number of different shades of colors that the screen is capable of displaying => 64K colors, 256K colors and 16 million colors, Obviously 16M is highest available range of colors and better than others.

68B colors
Pixel Density Pixel Density (PPI) is refers to the concentration of pixels on a particular display, measured in pixels per inch (ppi). Pixel density is calculated by dividing the diagonal pixel resolution of a display by its diagonal size, higher pixel density better display quality.

447 ppi (pixels per inch)
Touch Screen

Yes
Display Protection Display Protection => Gorilla Glass is a special alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use, It is always better to go for a smartphone with Gorilla Glass for that added protection and peace of mind.

Hardware

CPU The main chipset of the device.

Mediatek Dimensity 8400 Ultra (4 nm) Octa-core (1x3.25 GHz Cortex-A725 & 3x3.0 GHz Cortex-A725 & 4x2.1 GHz Cortex-A725)
GPU GPU (Graphics Processing Unit) is a single-chip processor designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display, This includes things such as lighting effects, object transformations, and 3D motion.

Mali-G720 MC7
RAM (Memory) RAM (Random Access Memory) is a type of computer memory that can be accessed randomly, any byte of memory can be accessed without touching the preceding bytes that allows information to be stored and accessed quickly from random locations. RAM is the most common type of memory found in computer systems, smartphones, tablets and other electronic devices.

12 GB
Internal Storage Internal Storage is a data storage space (flash memory) mostly used in smartphones, tablets and other electronic devices where operating system, apps, music, photos, videos, files and other user data Is stored.

256 GB, 512 GB
Memory Card Slot Memory Card Slot is a special slot for inserting a memory card. Memory cards allow you to expand the phone's built-in memory, A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote computing devices such as mobile phones, mp3 players, digital cameras.

No
Sensors Sensors are electronic components that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure and location, The output is generally a signal that is converted to use in computing systems, a location sensor, such as a GPS receiver is able to detect current location of your electronic device.

Fingerprint (under display, optical), accelerometer, gyro, proximity, compass

Software

Operating System OS => Every computer system run on a base software called Operating System (OS). Operating System controls all basic operations of the computer (such as smartphone, PDAs, tablet computers and other handheld devices). The Operating System allows the user to install and run third party applications (apps), apps are used to add new functionality to the device.

Android 15
User Interface UI or user interface of a device is the look and feel of the on-screen menu system. How it works, its color scheme, how it responds to button presses, all of these things are part of the user interface.

Network

SIM SIM (Subscriber Identity Module) is a small card that contains mobile network subscriber's account information. This allows the phone using the card to attach to a mobile network. The SIM card is most commonly associated with GSM and UMTS mobile networks. Moving a SIM card from one phone to another allows a subscriber to switch mobile phones without having to contact their mobile network carrier. SIM cards can also be used by a phone to store limited amounts of data, such as phone numbers and text messages.

GPS GPS The Global Positioning System is a satellite-based radio navigation system, GPS permits users to determine their position, velocity and the time 24 hours a day, in all weather, anywhere in the world, In order to locate your position, your device or GPS receiver must have a clear view of the sky.

Yes
NFC NFC (Near field communication) is a set of standards for smartphones and similar devices to establish peer-to-peer radio communications with each other by touching them together or bringing them into proximity, usually no more than a few inches.

Yes (market/region dependent)
Wireless Charging Wireless Charging (Inductive Charging) uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
