Display Comparison
The Xiaomi Redmi Note 13 Pro 4G boasts a notably brighter display, reaching a measured peak brightness of 1047 nits. This is a significant advantage for outdoor visibility compared to the Oppo A3x, which lacks published brightness data. While both likely utilize AMOLED panels given the market segment, the Redmi’s higher peak brightness translates to a more usable experience in direct sunlight. Bezels are expected to be similar, but the Redmi’s brightness is a clear differentiator. Color accuracy is unknown for both, but typical for this price range.
Camera Comparison
Detailed camera analysis is hampered by a lack of specific sensor information for both devices. However, the Redmi Note 13 Pro 4G is likely to feature a more sophisticated camera system, given Xiaomi’s emphasis on camera technology. While both phones likely include a primary camera, the Redmi’s marketing often highlights higher megapixel counts and features like optical image stabilization (OIS), which are absent from the Oppo A3x’s specifications. The inclusion of a 2MP macro camera on both devices is largely a marketing tactic and offers limited practical benefit.
Performance
The Oppo A3x’s Mediatek Dimensity 6300 (6nm) holds a slight architectural advantage over the Redmi Note 13 Pro 4G’s Helio G99 Ultra. The Dimensity 6300 utilizes two Cortex-A76 cores clocked at 2.4 GHz, compared to the G99 Ultra’s 2.2 GHz Cortex-A76 cores. However, the real-world performance difference will likely be minimal for most users. The 6nm process node of the Dimensity 6300 *should* offer slightly better power efficiency, but the Redmi’s optimized software and potentially larger battery capacity could offset this. Both phones feature a similar core configuration (6x Cortex-A55) for efficiency tasks.
Battery Life
The Xiaomi Redmi Note 13 Pro 4G shines in the battery and charging department. Its active use score of 11:36h demonstrates excellent endurance. Crucially, the 67W wired charging capability allows for a 50% charge in just 16 minutes and a full charge in 46 minutes. The Oppo A3x, with its 45W charging, takes 30 minutes to reach 50%, indicating a slower overall charging experience. While the A3x’s battery capacity is unknown, the Redmi’s combination of capacity and charging speed provides a significant advantage for users who prioritize minimizing downtime.
Buying Guide
Buy the Oppo A3x (China) if you prioritize raw CPU performance for tasks like app switching and light multitasking, and are comfortable with a slower charging speed. Buy the Xiaomi Redmi Note 13 Pro 4G if you value a brighter, more visible display in sunlight, significantly faster charging, and a longer-lasting battery in real-world usage scenarios.
Frequently Asked Questions
