Xiaomi Poco F3

  • Excellent value for money
  • Efficient Snapdragon 870 processor
  • Solid battery endurance (114h)

  • Slower 33W charging
  • Potentially less advanced camera system

OnePlus 9RT 5G

  • More powerful Snapdragon 888 processor
  • Blazing-fast 65W charging (29 min)
  • Likely superior camera image processing

  • Potentially higher price
  • Snapdragon 888 can run hotter under sustained load

Display Comparison

Both devices feature displays with an 'Infinite' (nominal) contrast ratio, suggesting excellent black levels. However, detailed display specs like peak brightness and color gamut coverage are missing. Given OnePlus’s history, the 9RT likely boasts a slightly more color-accurate panel. The Poco F3’s display is known for its 120Hz refresh rate, providing a fluid visual experience, but without LTPO technology, it won't dynamically adjust for power savings like some higher-end displays.

Camera Comparison

Both phones list 'Photo / Video' capabilities, lacking specific details. Given the market positioning, the OnePlus 9RT likely features a more sophisticated camera system. While megapixel counts are unknown, the 9RT benefits from OnePlus’s image processing expertise. The Snapdragon 888’s ISP (Image Signal Processor) is also more advanced, enabling better noise reduction and dynamic range. The Poco F3’s camera is competent, but likely prioritizes value over outright image quality. We can assume both phones will offer standard features like HDR and night mode.

Performance

The core difference lies in the chipsets. The OnePlus 9RT 5G’s Snapdragon 888 (5nm) is a step up from the Poco F3’s Snapdragon 870 (7nm). The 888’s Cortex-X1 prime core, clocked at 2.84 GHz, provides a significant boost in single-core performance, beneficial for tasks like app loading and responsiveness. The 870’s Kryo 585 cores are still very capable, but the 888’s Adreno 660 GPU offers superior graphics performance. However, the 5nm process of the 888 is crucial; the 7nm 870 is more thermally efficient, potentially leading to less throttling during extended gaming sessions. The 9RT’s performance advantage will be most noticeable in graphically intensive games and demanding applications.

Battery Life

The Poco F3 boasts an endurance rating of 114 hours, indicating solid battery life. However, the OnePlus 9RT 5G compensates for any potential battery capacity difference with its significantly faster 65W wired charging, achieving a 100% charge in just 29 minutes. The Poco F3’s 33W charging takes 52 minutes. This difference is substantial for users who prioritize minimizing downtime. While the Poco F3’s endurance rating suggests good efficiency, the 9RT’s charging speed is a game-changer.

Buying Guide

Buy the Xiaomi Poco F3 if you prioritize maximizing performance per dollar and are comfortable with slightly slower charging speeds. It’s ideal for budget-conscious gamers and everyday users. Buy the OnePlus 9RT 5G if you demand the fastest possible charging, a more powerful processor for demanding tasks, and are willing to spend a bit more for a smoother, more refined experience.

Frequently Asked Questions

❓ Will the Snapdragon 888 in the OnePlus 9RT 5G overheat during prolonged gaming sessions?
The Snapdragon 888 is known to generate more heat than the 870. However, OnePlus typically implements effective thermal management solutions. While some throttling is possible during extended, graphically demanding games, it shouldn't be a major issue for most users. The 9RT’s cooling system is likely more robust than the Poco F3’s.
❓ Is the difference in charging speed between 33W and 65W really that noticeable?
Absolutely. The OnePlus 9RT 5G’s 65W charging is a game-changer. Going from 0% to 100% in 29 minutes versus 52 minutes with the Poco F3 is a significant time saving, especially for users who frequently find themselves needing a quick top-up.
❓ Does the Poco F3 support high refresh rate gaming?
Yes, the Poco F3’s 120Hz display supports high refresh rate gaming, but the Snapdragon 870 may struggle to consistently maintain high frame rates in the most demanding titles at maximum settings. Expect to make some graphical compromises for smoother gameplay.
