Xiaomi 12S
- Superior chipset performance (Snapdragon 8+ Gen 1)
- Improved thermal management
- Efficient power consumption
- Slower wired charging compared to X80 Pro
- Missing reverse wireless charging
vivo X80 Pro
- Faster wired charging (80W)
- Potentially brighter display
- Dimensity 9000 option for alternative performance
- Snapdragon 8 Gen 1 can throttle under sustained load
- Potentially less efficient power consumption
Display Comparison
The vivo X80 Pro boasts a display capable of reaching 1014 nits of peak brightness, suggesting superior visibility in direct sunlight compared to the Xiaomi 12S (brightness data unavailable). Both displays feature an infinite contrast ratio, typical of OLED panels. However, without PWM dimming rate data for the 12S, it’s difficult to assess potential flicker-related eye strain. The X80 Pro’s larger display size (assumed, based on typical X80 Pro dimensions) may be preferable for media consumption, while the 12S likely aims for a more compact form factor.
Camera Comparison
Both phones are marketed as camera-centric, but detailed sensor information is limited. The X80 Pro likely features a larger main sensor, given vivo’s emphasis on camera technology. Both devices offer photo and video capabilities, but the X80 Pro’s image processing style is known for vibrant colors and strong contrast, while Xiaomi typically aims for a more natural look. Without specific aperture and OIS details, it’s difficult to definitively assess low-light performance, but the larger sensor on the X80 Pro would likely provide an advantage. The inclusion of a 2MP macro camera on either device is largely inconsequential.
Performance
The Xiaomi 12S’s Snapdragon 8+ Gen 1 (4nm) represents a significant architectural improvement over the Snapdragon 8 Gen 1 (4nm) found in the vivo X80 Pro. The ‘+’ variant features a redesigned CPU core configuration – 1x3.19 GHz Cortex-X2, 3x2.75 GHz Cortex-A710, and 4x1.80 GHz Cortex-A510 – offering higher clock speeds and improved efficiency. The X80 Pro offers a Dimensity 9000 option, with a similar core configuration (1x3.05 GHz Cortex-X2, 3x2.85 GHz Cortex-A710, and 4x1.80 GHz Cortex-A510), but the Snapdragon 8+ Gen 1 generally exhibits superior GPU performance and thermal management. This translates to less throttling during extended gaming sessions on the 12S.
Battery Life
Both the Xiaomi 12S and vivo X80 Pro achieve a similar endurance rating of 79 hours, suggesting comparable real-world battery life despite differing battery capacities (data unavailable for 12S). However, the X80 Pro’s 80W wired charging (0-100% in 38 minutes) is significantly faster than the 12S’s 67W charging (0-100% in 42 minutes). The X80 Pro also supports 50W wireless charging (0-100% in 50 minutes), matching the 12S’s 50W wireless charging (0-100% in 57 minutes). The X80 Pro also offers reverse wired charging, a feature absent on the 12S.
Buying Guide
Buy the Xiaomi 12S if you prioritize sustained gaming performance, efficient power usage, and a more responsive user experience. It’s ideal for power users and mobile gamers who demand consistent performance. Buy the vivo X80 Pro if you value camera versatility, exceptionally fast charging (80W wired vs 67W), and potentially a brighter display, and are willing to potentially trade some sustained performance for those features. The X80 Pro’s Dimensity 9000 variant may appeal to those seeking an alternative to Qualcomm’s silicon.
