Realme P3 Ultra
- Exceptional battery life (16:47h active use)
- Incredibly fast 80W wired charging
- Very bright display (1862 nits)
- Less powerful processor than the Snapdragon 8 Gen 2
- Limited camera details suggest a potentially weaker camera system
Xiaomi 13 Pro
- Top-tier performance with Snapdragon 8 Gen 2
- Faster 120W wired charging
- Wireless and reverse wireless charging capabilities
- Significantly shorter battery life (10:55h active use)
- Lower peak display brightness
Display Comparison
The Realme P3 Ultra boasts a significantly brighter display, reaching a measured 1862 nits compared to the Xiaomi 13 Pro’s 1253 nits. This translates to superior visibility under direct sunlight. While both utilize 4nm chipsets, the display brightness difference is a key advantage for the P3 Ultra. The Xiaomi 13 Pro’s ‘Infinite’ contrast ratio suggests a high-quality OLED panel, but without specific details on panel technology (LTPO or not), it’s difficult to assess its power efficiency compared to the P3 Ultra.
Camera Comparison
Both devices are listed as having Photo/Video capabilities, but detailed camera specifications are absent. Given the Xiaomi 13 Pro’s positioning as a flagship, it likely features a more sophisticated camera system with larger sensors and advanced image processing. The absence of specific sensor details for the P3 Ultra suggests a more mid-range camera experience. Without knowing aperture sizes or OIS implementation, it’s difficult to make a definitive judgment, but the Xiaomi 13 Pro is expected to deliver superior image quality, particularly in low-light conditions.
Performance
The Xiaomi 13 Pro’s Snapdragon 8 Gen 2 (Octa-core, 3.2 GHz Cortex-X3) is architecturally superior to the Realme P3 Ultra’s Dimensity 8350 Ultra. The Cortex-X3 core in the Snapdragon provides a performance edge in single-core tasks and demanding applications. However, the Dimensity 8350 Ultra’s configuration (1x3.35 GHz Cortex-A715 & 3x3.20 GHz Cortex-A715) is still very capable. The 4nm fabrication process is shared between both chipsets, but Qualcomm’s optimizations generally lead to better sustained performance and thermal management, potentially reducing throttling during extended gaming sessions. The Xiaomi 13 Pro also benefits from faster RAM speeds (likely LPDDR5x) which further enhances responsiveness.
Battery Life
The Realme P3 Ultra dominates in battery endurance, achieving an impressive 16:47h of active use, compared to the Xiaomi 13 Pro’s 10:55h. While the Xiaomi 13 Pro has an ‘Endurance Rating’ of 115h, this is a lab-based metric and doesn’t directly translate to real-world usage. The P3 Ultra’s 80W wired charging (47 minutes to 100%) is also faster than the 13 Pro’s 120W (19 minutes). However, the Xiaomi 13 Pro offers 50W wireless charging (36 minutes) and 10W reverse wireless charging, features absent on the P3 Ultra, which only offers 5W reverse *wired* charging. The faster wired charging of the Xiaomi 13 Pro is notable, but the P3 Ultra’s significantly longer battery life is a more impactful benefit for most users.
Buying Guide
Buy the Realme P3 Ultra if you need exceptional battery life, incredibly fast charging, and a bright display for outdoor use. This phone is ideal for power users, travelers, or anyone who dislikes battery anxiety. Buy the Xiaomi 13 Pro if you prioritize top-tier performance for gaming, video editing, or other resource-intensive applications, and value a premium build quality and potentially a more refined software experience.
