Display Comparison

The Realme 9 Pro+ boasts an 'Infinite' contrast ratio, a marketing term indicating a high-quality panel, though specific brightness nits aren't provided. The Umidigi F3 Pro's display specifications are absent, suggesting a more standard LCD panel. The Realme's likely superior contrast and potentially higher peak brightness will translate to a more vibrant and readable experience, especially outdoors. Without knowing the Umidigi's panel type, it's difficult to assess color accuracy, but the Realme likely has the edge here due to its positioning.

Camera Comparison

Camera details are limited for both devices. The Realme 9 Pro+ likely features a more sophisticated camera system, benefiting from the processing power of the Dimensity 920. While both phones likely have multi-camera setups, the Realme's sensor size and lens apertures are expected to be superior, leading to better low-light performance and image quality. The Umidigi F3 Pro will likely rely more on software processing to compensate for potentially smaller sensors. Without specific sensor details, it's difficult to make a definitive judgment, but the Realme's chipset gives it a clear advantage in image processing capabilities.

Performance

The core difference lies in the chipsets. The Realme 9 Pro+'s Mediatek Dimensity 920 (6nm) is a significant step up from the Umidigi F3 Pro's Dimensity 700 (7nm). The 920 features faster Cortex-A78 cores (2.5 GHz vs 2.2 GHz) and a more efficient 6nm process, resulting in noticeably quicker performance in demanding applications and games. While both phones share the same Cortex-A55 efficiency cores, the 920's superior architecture and process node will lead to better sustained performance and potentially improved thermal management. The Realme's likely use of faster LPDDR5 RAM (spec not provided, but typical for this tier) further enhances its performance advantage.

Battery Life

The Realme 9 Pro+’s 60W wired charging with PD3.0 is a game-changer, promising a full charge in just 44 minutes. The Umidigi F3 Pro’s 18W charging is considerably slower. While the Umidigi F3 Pro’s battery capacity isn’t specified, the Realme 9 Pro+ boasts an endurance rating of 117 hours, suggesting a large battery combined with efficient power management. The faster charging of the Realme 9 Pro+ significantly reduces downtime, making it ideal for users who need to quickly top up their battery.

Buying Guide

Buy the Umidigi F3 Pro if you need a reliable 5G phone for basic tasks, prioritize battery life over raw performance, and are on a very tight budget. Buy the Realme 9 Pro+ if you prefer faster app loading, smoother multitasking, quicker charging, and are willing to spend more for a more refined experience. The Realme is geared towards users who demand more from their smartphone.

Frequently Asked Questions

❓ Does the Dimensity 920 in the Realme 9 Pro+ get noticeably warmer during extended gaming sessions?
While the Dimensity 920 is a powerful chip, it can generate heat under sustained load. Realme typically employs thermal management solutions, but users engaging in prolonged gaming may experience some warming. The 6nm process helps mitigate this compared to older nodes, but it's still a factor to consider.
❓ Is the 18W charging on the Umidigi F3 Pro sufficient for daily use, or will I be constantly waiting for it to charge?
18W charging is relatively slow by today's standards. While it will charge the phone overnight, users who frequently need to top up their battery throughout the day will find it inconvenient. Expect a full charge to take well over two hours.
❓ How does the Realme 9 Pro+'s software experience compare to other Realme phones, and is there a lot of bloatware?
Realme's UI (based on Android) is known for its customization options, but it also often includes pre-installed apps (bloatware). While the amount of bloatware has decreased in recent versions, users may still find some unwanted apps. It's generally manageable, but something to be aware of.
❓ Can the Umidigi F3 Pro handle demanding games like PUBG Mobile or Call of Duty Mobile at high settings?
The Dimensity 700 can run these games, but you'll likely need to compromise on graphics settings to maintain a smooth frame rate. Expect to play at medium settings for a more consistent experience. The Realme 9 Pro+ will offer a significantly smoother experience at higher settings.
