- Ultra-fast 120W wired charging
- Higher peak display brightness
- Potentially better sustained performance due to cooling
- Lower battery cycle life (800 cycles)
- No wireless charging
Display Comparison
The Realme GT 7 Pro’s display is the clear winner in terms of peak brightness, reaching a measured 2336 nits compared to the Xiaomi 15’s 1517 nits. This translates to significantly better visibility under direct sunlight. While both likely utilize LTPO technology for adaptive refresh rates (not specified in the data, but standard for this class), the Realme’s brightness advantage is undeniable. The Xiaomi 15 may offer superior color accuracy or calibration, but without specific data, this remains speculative. The higher brightness of the GT 7 Pro will be particularly beneficial for users who frequently use their phones outdoors or consume HDR content.
Camera Comparison
The provided data lacks camera specifications, making a direct comparison impossible. However, given the Realme GT series’ history, it’s reasonable to expect a focus on high-resolution sensors and versatile camera systems. The Xiaomi 15, traditionally, emphasizes computational photography and image processing. Without sensor size, aperture, or OIS details, we can only speculate. The absence of any mention of a telephoto lens on either device suggests a potential weakness in zoom capabilities compared to competitors.
Performance
Both devices are powered by the Qualcomm SM8750-AB Snapdragon 8 Elite (3 nm) with the same CPU configuration: an octa-core setup featuring 2x4.32 GHz Oryon V2 Phoenix L cores and 6x3.53 GHz Oryon V2 Phoenix M cores. This means raw processing power will be virtually identical. Performance differences will likely stem from thermal management and sustained performance. While not specified, Realme’s GT series often prioritizes aggressive cooling solutions, potentially allowing for longer peak performance during demanding tasks like gaming. Both devices utilize LPDDR5x RAM, ensuring fast memory access speeds.
Battery Life
The Realme GT 7 Pro dominates in battery performance. Its 75:23h endurance rating significantly surpasses the Xiaomi 15’s 63:26h. This translates to a real-world difference of over an hour in active use (17:31h vs 16:28h). Crucially, the GT 7 Pro’s 120W wired charging is a game-changer, achieving a 50% charge in just 13 minutes and a full charge in 30-37 minutes (depending on region). The Xiaomi 15’s 90W wired charging is respectable, but considerably slower. The inclusion of 50W wireless charging and 10W reverse wireless charging on the Xiaomi 15 adds convenience, but doesn’t compensate for the slower wired charging speed or lower overall endurance. The GT 7 Pro also has a slightly higher battery cycle count (800 vs 1000), which may indicate a slightly faster degradation rate over the long term.
Buying Guide
Buy the Xiaomi 15 if you prioritize a stunningly bright display for outdoor visibility and content consumption, and are comfortable with a more frequent charging schedule. Buy the Realme GT 7 Pro if you demand exceptional battery life, need the fastest possible charging speeds, and value long-term usability without constantly seeking a power outlet.
