Xiaomi 15 Ultra – A New Flagship in the Making
The most recent attempt by Xiaomi to conquer the high-end smartphone market, which is dominated by cameras, is the Xiaomi 15 Ultra. with a powerful Leica-tuned camera system, superior internals, bold design, and cutting-edge features for those who care as much about performance as they do about photography.
The Launch & Positioning:
Xiaomi officially unveiled the Xiaomi 15 Ultra on February 27, 2025 in China. Rumors and leaks had sparked interest in its camera upgrades and core hardware prior to the global unveiling. It later made its global debut around the Mobile World Congress (MWC) 2025.
Pricing & Market Strategy:
The lowest specification of the base variant costs 6,499 yuan, or approximately $1,400.49 USD, in China. Meanwhile, in markets like the U.K., the 16 GB / 512 GB model is priced at £1,299, with the 1 TB version at £1,499. Additionally, for an additional fee of CNY 999 (USD 137), Xiaomi offers an optional Photography Kit with hardware controls and filters.
Design & Build Quality:
The Xiaomi 15 Ultra is about 229 grams in weight and measures 161.3 x 75.3 x 9.48 mm. The large camera hardware makes the device heavier and thicker than a typical flagship. Materials: a metal frame with vegan leather paneling and metal surfaces gives the impression of being of high quality.
Camera Module & Aesthetic Theme
The back is dominated by a circular “camera island” reminiscent of a traditional camera lens layout. Its boldness and symmetry serve to visually convey its photographic intent. Leica’s insignia and brand name “Ultra” emphasize the company’s identity even more.
Durability & Water Resistance
It carries an IP68 rating for dust and water resistance. Xiaomi uses Shield Glass 2.0 to protect the back glass and display, aiming for better drop resistance.
Display & Visual Experience:
It has an AMOLED (LTPO) display that is 6.73 inches wide. It is effectively QHD+ with a resolution of 3,200 x 1,440 pixels.
Refresh Rate & Edge Behavior
It has a peak brightness rating of 3,200 nits, making it one of the brightest displays available. The LTPO panel’s variable refresh rate maintains balance between smoothness and battery efficiency. The display has a slight curved edge, which makes it easier to hold but can also lead to some accidental touches. In testing, it remains responsive and well-behaved.
Performance & Internal Hardware:
The Qualcomm Snapdragon 8 Elite chipset is housed inside. This is the most prominent chip in the 3 nm class, designed for top-tier competition. Utilizing UFS 4.1 technology, Xiaomi 15 Ultra is paired with 16 GB of LPDDR5X RAM and offers 512 GB or 1 TB of storage. These hardware specs ensure snappy app loading, multitasking, and data throughput.
Cooling System & Thermal Management
A “two-way design” cooling architecture is utilized by Xiaomi. According to Xiaomi, the design enables the phone to stay about 6.6°C cooler under heavy load versus an iPhone 16 Pro Max in comparable scenarios. In practice, reviewers observed that it becomes warm but not unbearably so during prolonged gaming.
Battery, Charging & Endurance:
The battery in the global version is 5,410 mAh. In the Chinese variant, reports suggest a 6,000 mAh pack. Xiaomi 15 Ultra has wired charging support for 90W HyperCharge, which is fast but not the fastest in the industry. Up to 80W of wireless charging is supported. Although less talked about, reverse wireless charging is a possibility (typical for flagship models).
Real-World Usage & Longevity
It easily lasts a day and a half in moderate daily use, sometimes two, depending on settings and usage, according to reviewers. Battery drain is greater during heavy usage with a high refresh rate and camera work, but overall endurance is strong.
Camera System:
Xiaomi 15 Ultra features a quad rear camera system:
- 50 MP main (Sony LYT-900)
- 50 MP ultra-wide (Samsung JN5)
- 50 MP telephoto, ~3× optical zoom (Sony IMX858)
- 200 MP periscope telephoto, ~4.3× zoom (Samsung HP9)
Additionally, the front (selfie) camera is 32 MP.
Main Sensor & Low-Light Capability
The 50 MP main sensor of the Xiaomi 14 Ultra’s predecessor was the same one-inch Sony LYT-900. Due to its large size and optics, Xiaomi 15 Ultra is able to capture a lot of light and preserve detail in low-light scenes. Night shots demonstrated controlled grain and excellent clarity in tests.
Ultra-Wide & Telephoto Sensors
The Samsung JN5’s 50 MP ultra-wide sensor has a good color and exposure consistency and a wide field of view (115°). Portrait and mid-range zoom are made easier by the 50 MP telephoto (3). However, reviewers discovered that the color, contrast, and punchiness of 3’s images are frequently off.
Video Recording & Stabilization
The Xiaomi 15 Ultra supports high-end video capture, up to 4K at 120 fps, with stabilization (OIS + EIS) and advanced modes to aid creative videography. Dynamic range and low-light video are made easier by the large sensor.
Software, Features & UI:
HyperOS 2 is installed on top of Android 15 on the Xiaomi 15 Ultra. In place of MIUI, Xiaomi has rebranded its software platform as HyperOS.
Features & Customizations
There are numerous built-in camera features, themes, and customizations. However, this also implies complexity. The user interface may be overpowering or cluttered for some users. Reviewers noted quirks: split notification shade is confusing; notification reliability issues early on; and some apps failing to refresh correctly (e.g. Teams) independently
Updates & Optimizations
Software bugs, incorrect notification behavior, and app compatibility issues are among the new features. Xiaomi will need to support updates and patches to fix these over time.
Connectivity & Extra Features:
The most recent version of Bluetooth, NFC, and 5G are all supported by the phone. Both connectivity and signal strength were satisfactory in reviews.
Sensors and Biometrics
Sensors include gyroscope, accelerometer, proximity, compass, etc. Although not the fastest, the fingerprint sensor built into the display works reliably. Face unlock covers a wide field of view. The haptics have been improved to meet flagship expectations.
Speakers & Sound:
The sound is powerful and rich through stereo speakers. Most likely, spatial audio tuning or Dolby Atmos is integrated. The audio quality was clean for calls, media, etc., according to reviewers.
Ports, USB, Expansion
Xiaomi 15 Ultra has USB 3.2 Gen 2 support and a USB-C port. The storage is fixed and there is no microSD slot.

- Less ideal for those looking for compact, lightweight, or budget-friendly phones
