Realme 9 Pro+

  • More power-efficient chipset (Dimensity 920)
  • Slightly longer battery endurance rating
  • Potentially better sustained performance under heavy load

  • Dimmer display, difficult to see in sunlight
  • Slower charging speed (60W vs 67W)

Xiaomi Poco F4

  • Significantly brighter display (1003 nits)
  • Faster charging (67W, 38 minutes to full)
  • Stronger GPU performance (Snapdragon 870)
  • Generally more refined image processing

  • Slightly lower battery endurance rating
  • Potentially more thermal throttling under extreme load

Display Comparison

The Poco F4’s display is the clear winner here, boasting a measured peak brightness of 1003 nits compared to the Realme 9 Pro+’s 613 nits. This difference is immediately noticeable outdoors, where the Poco F4 remains easily readable in direct sunlight. While both feature similar resolutions, the Poco F4’s higher brightness and infinite contrast ratio (nominal) translate to a more immersive viewing experience. The Realme 9 Pro+’s display, while adequate, feels comparatively dim and lacks the vibrancy of the Poco F4.

Camera Comparison

Both devices offer capable camera systems, but detailed sensor information is limited. Given the market positioning, it’s reasonable to assume both rely on similar primary sensors. However, the Poco F4’s image processing is generally regarded as more refined, producing more natural-looking photos with better dynamic range. The Realme 9 Pro+’s camera likely leans towards more saturated colors, a common trait of Realme’s image processing. Without specific sensor details, it’s difficult to definitively declare a winner, but the Poco F4’s software advantage gives it a slight edge.

Performance

Both phones are equipped with capable chipsets, but they differ in architecture and efficiency. The Poco F4’s Snapdragon 870 (7nm) features a Kryo 585 core configuration with a peak clock speed of 3.2 GHz, offering strong single-core and multi-core performance. The Realme 9 Pro+’s Dimensity 920 (6nm) utilizes a dual-cluster architecture with Cortex-A78 and Cortex-A55 cores, peaking at 2.5 GHz. While the Dimensity 920’s 6nm process offers theoretical efficiency gains, the Snapdragon 870’s superior GPU and optimized software integration often result in smoother gaming performance. The Poco F4 is likely to exhibit less thermal throttling during prolonged gaming sessions.

Battery Life

The Realme 9 Pro+ has an endurance rating of 117 hours, while the Poco F4 scores 101 hours. However, this doesn’t tell the whole story. The Poco F4 compensates for its slightly smaller battery with significantly faster 67W charging, achieving a full charge in just 38 minutes, compared to the Realme 9 Pro+’s 44 minutes. This faster charging speed is a significant convenience factor. The Dimensity 920’s 6nm process contributes to slightly better battery efficiency, but the difference is unlikely to be substantial in real-world usage.

Buying Guide

Buy the Realme 9 Pro+ if you prioritize sustained performance under load and value a slightly more power-efficient chipset for extended gaming sessions. Buy the Xiaomi Poco F4 if you demand a vibrant, easily visible display, faster charging speeds, and a generally more responsive user experience, even if it means slightly higher power consumption.

Frequently Asked Questions

❓ Does the Snapdragon 870 in the Poco F4 exhibit noticeable thermal throttling during extended gaming sessions?
While the Snapdragon 870 is a capable chip, it can experience some thermal throttling under sustained heavy load. However, the Poco F4’s cooling system is generally effective at mitigating this, and throttling is unlikely to be severe enough to significantly impact gameplay. The Realme 9 Pro+'s Dimensity 920 may maintain slightly cooler temperatures, but the Poco F4's GPU performance advantage often outweighs this.
❓ How does the 67W charging on the Poco F4 compare to other fast charging solutions in terms of heat generation?
67W charging is relatively fast, but Xiaomi has implemented safeguards to minimize heat generation during the charging process. While the phone will warm up during charging, it shouldn't become uncomfortably hot. The Poco F4’s charging speed is significantly faster than the Realme 9 Pro+'s 60W charging, reducing the overall time the phone spends at higher temperatures.
❓ Is the difference in display brightness between the Poco F4 and Realme 9 Pro+ noticeable in everyday use, or only in direct sunlight?
The difference is noticeable even in indoor environments. The Poco F4’s brighter display makes colors appear more vibrant and images more punchy. In direct sunlight, the difference is dramatic, with the Poco F4 remaining easily readable while the Realme 9 Pro+ becomes washed out.
