Display Technology Advancements
Display excellence remains a consistent strength across the Xiaomi 15 Series, with all models featuring LTPO AMOLED technology that enables variable refresh rates.
The standard model offers FHD+ resolution with 1-120Hz adaptation, while both Pro and Ultra variants implement QHD+ panels with more advanced 1-144Hz variable refresh capabilities.
| Model | Display Size | Resolution | Refresh Rate | Peak Brightness | Special Features |
|---|---|---|---|---|---|
| Xiaomi 15 | 6.36″ | 2670 x 1200 | 1-120Hz | 2000 nits | Flat panel design |
| Xiaomi 15 Pro | 6.73″ | 3200 x 1440 | 1-144Hz | 2500 nits | Micro-curved edges |
| Xiaomi 15 Ultra | 6.73″ | 3200 x 1440 | 1-144Hz | 3000 nits | Under-display camera |
Common across all variants are HDR10+ and Dolby Vision certification, 10-bit color depth, and Xiaomi’s ProXDR enhancement algorithm that dynamically optimizes content for improved dynamic range.
The Ultra model introduces the most significant innovation with an under-display selfie camera that eliminates notches entirely, while the standard and Pro models utilize minimal punch-hole implementations.
Color accuracy represents another shared strength, with all models achieving Delta E < 1 performance and 100% DCI-P3 coverage, ensuring precise reproduction for both content creation and consumption.
Advanced eye protection features including DC dimming and high-frequency PWM drive further enhance the user experience during extended viewing sessions.
Performance Architecture
The entire Xiaomi 15 Series is powered by Qualcomm’s Snapdragon 8 Gen 3 platform, with the Pro and Ultra models featuring the enhanced “Leading Version” with higher clock speeds.
This unified approach to processing architecture ensures consistent performance characteristics across the lineup, with differentiation occurring primarily through cooling systems, memory configurations, and storage allocations.
| Model | Chipset | RAM Options | Storage Options | Cooling System |
|---|---|---|---|---|
| Xiaomi 15 | SD 8 Gen 3 | 8/12GB LPDDR5X | 256/512GB UFS 4.0 | VC 3,600mm² |
| Xiaomi 15 Pro | SD 8 Gen 3 LV | 12/16GB LPDDR5X | 256/512GB/1TB UFS 4.0 | VC 5,000mm² |
| Xiaomi 15 Ultra | SD 8 Gen 3 LV | 16GB LPDDR5X | 512GB/1TB UFS 4.0 | VC 5,500mm² with graphene |
Thermal management represents a key differentiator between models, with progressively more sophisticated vapor chamber implementations as the series ascends.
The Ultra model’s advanced cooling system enables sustained performance during intensive tasks like mobile gaming or computational photography, maintaining peak processing capabilities for extended periods without throttling.
Benchmark performance across the series places all models at the pinnacle of Android capabilities, with AnTuTu scores ranging from 1.8 million for the standard model to over 2 million for the Ultra variant.
These figures translate to essentially flawless performance across all usage scenarios, with differences becoming apparent only during the most demanding sustained workloads.
Camera System Innovation
Imaging capabilities showcase Xiaomi’s most significant technological advancements, with the entire series benefiting from the company’s partnership with Leica.
This collaboration influences both optical design and image processing, creating a distinctive photographic identity across the lineup.
