vivo iQOO 12

  • Superior battery life (13:30h active use)
  • High peak display brightness (1425 nits)
  • Potentially better thermal management due to larger chassis

  • Camera details are currently unknown
  • Software experience may not appeal to all users

Xiaomi Redmi K70 Pro

  • Fastest charging speed (100% in 18 min)
  • Wider charger compatibility (PD3.0, QC3+)
  • MIUI software ecosystem

  • Shorter battery life compared to iQOO 12
  • Potential for more aggressive throttling under sustained load

Display Comparison

Both devices are expected to feature high-refresh-rate displays, but the iQOO 12 boasts a measured peak brightness of 1425 nits. This translates to superior visibility in direct sunlight compared to the Redmi K70 Pro, which lacks a published brightness figure. While both likely utilize AMOLED technology, the iQOO 12’s higher peak brightness is a significant advantage for outdoor users. The absence of LTPO information for either device suggests potential for higher power consumption at lower refresh rates, impacting battery life.

Camera Comparison

Context data is limited regarding camera capabilities. However, given the market positioning of both brands, we can infer a focus on versatile camera systems. The absence of sensor size or megapixel counts necessitates caution. The Redmi K70 Pro, historically, has leaned towards computational photography, while iQOO often prioritizes natural image processing. Without detailed specifications, it’s difficult to definitively declare a winner, but the presence of OIS (Optical Image Stabilization) on the main sensor would be a crucial differentiator, favoring the device that includes it.

Performance

The core of both phones is the Qualcomm SM8650-AB Snapdragon 8 Gen 3 (4nm). Critically, both share the *exact same* CPU configuration: 1x3.3 GHz Cortex-X4, 3x3.2 GHz Cortex-A720, 2x3.0 GHz Cortex-A720, and 2x2.3 GHz Cortex-A520. This means CPU-bound tasks will perform nearly identically. Performance differences will likely stem from thermal management and sustained clock speeds. While both utilize a 4nm process, the iQOO 12’s larger chassis *may* allow for a more effective cooling solution, potentially mitigating throttling during prolonged gaming sessions. RAM specifications are not provided, but both are expected to offer LPDDR5x options for fast memory access.

Battery Life

The iQOO 12’s 13:30-hour active use score is a key differentiator. While the Redmi K70 Pro shares the same 120W wired charging capability, achieving a full charge in a claimed 18 minutes, the iQOO 12’s longer battery life provides a more substantial benefit for users who don’t want to constantly top up. The inclusion of PD3.0 and QC3+ on the Redmi K70 Pro offers broader charger compatibility, but the iQOO 12’s endurance is a more impactful real-world advantage.

Buying Guide

Buy the vivo iQOO 12 if you need exceptional battery life for demanding daily use, including extended gaming or video consumption. Buy the Xiaomi Redmi K70 Pro if you prioritize the fastest possible charging speeds and appreciate Xiaomi’s MIUI software ecosystem, and are comfortable with potentially slightly shorter battery runtimes.

Frequently Asked Questions

❓ Does the 120W charging on the Redmi K70 Pro significantly degrade battery health over time?
While 120W charging is incredibly fast, Xiaomi employs battery protection technologies to mitigate degradation. However, consistently using extremely fast charging *can* contribute to slightly faster battery wear compared to slower charging methods. The Redmi K70 Pro's charging system includes multiple safeguards, but long-term battery health will still depend on usage patterns.
❓ How does the thermal performance of the Redmi K70 Pro hold up during extended gaming sessions of titles like Genshin Impact?
Given the shared Snapdragon 8 Gen 3 chipset, both phones will experience heat generation during intensive gaming. The Redmi K70 Pro’s thermal solution, while likely effective, may be constrained by its form factor. Expect some degree of throttling after prolonged gaming, potentially leading to slightly reduced frame rates. Monitoring CPU and GPU temperatures during gameplay is recommended.
❓ Is the iQOO 12's battery life impacted significantly when using the 120W charging frequently?
The iQOO 12's robust 13:30-hour active use score suggests a large enough battery capacity to absorb the impact of frequent fast charging. While all batteries degrade over time, the iQOO 12's larger battery reserve provides a buffer, meaning you can utilize the 120W charging without immediately noticing a substantial drop in overall battery health.
