Display Comparison

The Realme 9 Pro+ boasts an 'Infinite' (nominal) contrast ratio, suggesting a vibrant display experience, though specific brightness nits are not provided. The Redmi 20X lacks detailed display specifications, implying a more standard LCD panel. While both likely feature similar resolutions, the Realme’s potential for higher contrast and color accuracy gives it an edge for media consumption. The absence of refresh rate data for the Redmi 20X suggests it may be limited to 60Hz, while the 9 Pro+ is likely to offer a smoother experience with a higher refresh rate (though not specified in the provided data).

Camera Comparison

Detailed camera specifications are limited. However, the Realme 9 Pro+ likely benefits from a more advanced image signal processor (ISP) integrated within the Dimensity 920, leading to better image processing and potentially improved low-light performance. Without sensor size or aperture data for either device, it’s difficult to make definitive claims. The Redmi 20X likely relies on more basic image processing, while the 9 Pro+ could offer features like improved dynamic range and noise reduction. The absence of details suggests neither phone will be a standout camera performer, but the Realme has the potential for better results.

Performance

The core difference lies in the chipsets. The Realme 9 Pro+’s Dimensity 920 (6nm) is a substantial upgrade over the Redmi 20X’s Dimensity 700 (7nm). The 920 features faster Cortex-A78 cores (2.5 GHz vs 2.2 GHz) and a more efficient 6nm process, translating to noticeably improved CPU and GPU performance. This means smoother multitasking, faster app loading times, and a better gaming experience on the Realme. While both utilize the same Cortex-A55 efficiency cores, the 920’s architecture and process node provide a clear advantage. The Redmi 20X will handle everyday tasks adequately, but will struggle with demanding applications.

Battery Life

The Realme 9 Pro+’s 60W charging is a game-changer, advertised to reach 100% in just 44 minutes. This significantly reduces downtime compared to the Redmi 20X’s 18W charging. While the Redmi 20X’s battery capacity isn’t specified, the Realme 9 Pro+ boasts an endurance rating of 117 hours, suggesting a large battery capacity coupled with efficient power management. The faster charging of the 9 Pro+ effectively mitigates any potential battery capacity disadvantage, making it the more convenient option for users who frequently need to top up their phone.

Buying Guide

Buy the Xiaomi Redmi 20X if you need a reliable, everyday smartphone with decent performance for basic tasks and prioritize value above all else. It’s ideal for users who don’t heavily game or require extremely fast charging. Buy the Realme 9 Pro+ if you prefer a smoother, more responsive experience, especially for gaming and multitasking, and value the convenience of incredibly fast 60W charging. This phone is geared towards users who demand more from their device and are willing to pay a premium for it.

Frequently Asked Questions

❓ Will the Realme 9 Pro+ get noticeably hotter than the Redmi 20X during extended gaming sessions?
The Dimensity 920 in the Realme 9 Pro+ is a more powerful chip, and therefore generates more heat under sustained load. While Realme likely incorporates thermal management solutions, it's reasonable to expect some degree of warming during prolonged gaming. The Redmi 20X’s Dimensity 700 will likely remain cooler, but at the cost of performance.
❓ Is the 60W charging on the Realme 9 Pro+ compatible with all USB-C chargers?
The Realme 9 Pro+ supports PD3.0, meaning it *should* work with many USB-C Power Delivery chargers. However, to achieve the full 60W charging speed, you'll need a charger specifically rated for that wattage and supporting the PD3.0 protocol. Using a standard charger will still charge the phone, but at a slower rate.
❓ How does the Dimensity 700 in the Redmi 20X perform with popular apps like TikTok and Instagram?
The Dimensity 700 is perfectly capable of handling social media apps like TikTok and Instagram without issue. You shouldn't experience any lag or slowdowns during normal usage. However, if you frequently edit and upload videos directly from the phone, the Realme 9 Pro+'s more powerful processor will offer a smoother experience.
