The
Xiaomi 15 Ultra is a flagship smartphone that aims to redefine mobile
photography while delivering top-tier performance and a premium design. As the
successor to the highly acclaimed Xiaomi 14 Ultra, this device carries forward
the brand’s partnership with Leica and introduces notable upgrades,
particularly in its camera system. After exploring its features, performance,
and quirks, here’s a detailed review of the Xiaomi 15 Ultra, based on insights
from various sources and critical analysis
Xiaomi 15 ultra
Design
and Build: Premium but PolarizingThe Xiaomi 15 Ultra sports a robust and
premium build, featuring a high-strength aluminum frame, IP68 dust and water
resistance, and a choice of glass-fiber or eco-leather back. The Silver Chrome
variant, with its retro camera-inspired aesthetic, is particularly striking,
evoking Leica’s classic design language. However, the massive circular camera
module on the back is a double-edged sword: it’s a bold statement for
photographers but makes the phone top-heavy and prone to catching on pockets.
At 226-229 grams and 9.4mm thick, it’s heftier than competitors like the
Samsung Galaxy S25 Ultra, which might feel cumbersome for some users.The
6.73-inch LTPO AMOLED display is a standout, offering QHD+ resolution (3200 x
1440), a 120Hz refresh rate, and a peak brightness of 3200 nits. Protected by
Xiaomi’s Shield Glass 2.0, it’s durable and vibrant, supporting Dolby Vision
and HDR10+ for an immersive viewing experience. However, the thick bezels and
slight curvature may not feel as modern as some rivals, and the display’s PWM
dimming at 120Hz could cause eye strain for sensitive users.
camera : A Photographer’s Dream (with Caveats)The Xiaomi 15 Ultra’s
Leica-co-engineered quad-camera system is its crown jewel, designed to rival
dedicated cameras. The setup includes:50MP Main (1-inch LYT-900, f/1.6):
Delivers exceptional dynamic range, detail, and low-light performance, though
it lacks the variable aperture of the 14 Ultra, limiting creative control for
effects like starbursts.50MP Ultrawide (f/2.2, 115°): A slight downgrade from
the 14 Ultra’s f/1.8, resulting in weaker low-light performance and less detail
compared to competitors.50MP 3x Telephoto (70mm, f/1.8): Offers sharp,
consistent shots with macro capabilities, ideal for portraits.200MP 4.3x
Periscope (100mm, f/2.6): The star of the show, providing industry-leading zoom
performance with stunning detail, even at long ranges. It’s a game-changer for
telephoto photography.The camera excels in most scenarios, producing vibrant,
natural images with Leica’s signature color tuning. It’s particularly
impressive in low light, with minimal noise and warm white balance, though some
oversaturation and color casts can occur. The 200MP telephoto sets a new
benchmark for zoom, outshining rivals like the iPhone 16 Pro Max and Samsung
Galaxy S25 Ultra in long-range shots. However, the shallow depth of field on
the main camera can blur background subjects in group shots or 8K video, which
may disappoint users needing sharp focus across the frame.Video performance is
strong, with 8K@30fps, 4K@60fps, and LOG capture, but it lags behind the iPhone
16 Pro Max and Huawei Pura 70 Ultra in stabilization, exposure adaptation, and
detail
The 32MP selfie camera is a weak link, lacking autofocus and
producing mediocre results compared to flagship rivals.
Performance: A Beast Under the HoodPowered by Qualcomm’s
Snapdragon 8 Elite chipset, paired with up to 16GB of RAM and 1TB of UFS 4.1
storage, the Xiaomi 15 Ultra is a performance juggernaut. It handles
multitasking, gaming, and demanding apps with ease, staying cool thanks to a 3D
Dual-Channel Iceloop cooling system. Benchmarks show it competes with the best,
though some throttling under sustained loads has been noted.Running HyperOS 2.0
on Android 15, the software experience is smooth and customizable, with AI
tools like text summarization, translation, and photo editing. However,
bloatware and inconsistent AI features (e.g., the Mi Browser’s AI summary often
fails) detract from the experience. The integration of Google Gemini and six
years of software support are welcome, but the lack of offline AI capabilities
and occasional bugs may frustrate users.
Battery and Charging: Solid but Not GroundbreakingThe Xiaomi
15 Ultra’s 5,410mAh battery (smaller than the 6,000mAh in the Chinese variant
due to EU regulations) offers good endurance, lasting a full day with heavy
use, including photography and gaming. However, real-world tests suggest it’s
not as impressive as claimed, with some users reporting faster drain under
intensive tasks.Charging is a highlight, with 90W wired HyperCharge (full
charge in ~40 minutes) and 80W wireless charging, though the lack of a charger
in the box (only a USB-A-to-C cable included) is a letdown at this price. The
absence of Qi2 support limits compatibility with magnetic accessories, unlike
some Android competitors.
Pros:Exceptional Leica quad-camera system, especially the
200MP telephoto for zoom.Powerful Snapdragon 8 Elite with smooth multitasking
and gaming.Vibrant 6.73-inch AMOLED display with strong brightness and HDR
support.Premium build with IP68 rating and durable Shield Glass 2.0.Fast 90W
wired and 80W wireless charging.
