vivo X300
- Exceptional battery life (52:15h endurance)
- Brighter display (1930 nits)
- Longer battery lifespan (1200 cycles)
- Slower charging speed (90W)
- Potentially lower peak performance compared to Snapdragon
vivo iQOO 12 Pro
- Faster charging (120W wired, 50W wireless)
- Superior processing power (Snapdragon 8 Gen 3)
- Optimized for gaming
- Likely shorter battery life
- Potentially more thermal throttling under sustained load
Display Comparison
The vivo X300 boasts a display capable of reaching a measured 1930 nits of peak brightness, providing excellent visibility in direct sunlight. While the iQOO 12 Pro’s display specs aren’t provided, iQOO typically prioritizes high refresh rates. The X300’s brightness advantage is significant, and the absence of LTPO information for the iQOO 12 Pro suggests it may not be as dynamically power-efficient in varying content. This impacts overall battery consumption.
Camera Comparison
Without detailed camera specifications, a direct comparison is difficult. However, both phones likely feature high-resolution main sensors. The iQOO series often emphasizes computational photography for vibrant, social media-ready images, while the X-series tends towards more natural color reproduction. The absence of information on OIS and aperture sizes prevents a deeper analysis, but the chipset’s ISP capabilities will play a crucial role in image processing speed and quality.
Performance
The core difference lies in the chipsets. The iQOO 12 Pro’s Snapdragon 8 Gen 3 (4nm) is a proven performer, utilizing a 1x3.3 GHz Cortex-X4 prime core. The vivo X300’s Dimensity 9500 (3nm) employs a more complex core configuration – 1x4.21 GHz C1-Ultra, 3x3.5 GHz C1-Premium, and 4x2.7 GHz C1-Pro. The 3nm process of the Dimensity 9500 *should* offer better power efficiency, but the Snapdragon 8 Gen 3’s architecture is optimized for sustained performance. The iQOO 12 Pro will likely excel in demanding tasks and gaming, while the X300 aims for a smoother, more efficient experience.
Battery Life
The vivo X300’s 52:15h endurance is a standout feature, indicating exceptional battery life. This is coupled with a 1200 cycle lifespan, promising longevity. The iQOO 12 Pro compensates for potentially lower endurance with significantly faster charging: 120W wired versus 90W on the X300. This translates to a much quicker 0-100% charge time. The iQOO 12 Pro also offers 50W wireless charging compared to the X300’s 40W, further reducing top-up times. The X300’s reverse wired charging is a convenient addition.
Buying Guide
Buy the vivo X300 if you need exceptional battery life, a brighter screen for outdoor visibility, and a more balanced, refined user experience. Buy the iQOO 12 Pro if you prioritize maximum gaming performance, the fastest possible charging speeds, and are willing to trade some battery endurance for that extra power.
