Display Comparison

The Poco M4 Pro boasts a significantly brighter display, reaching a measured 737 nits, compared to an unspecified brightness for the Realme 9i. This difference is crucial for outdoor visibility. Both devices feature an 'infinite' (nominal) contrast ratio, typical for IPS LCD panels. While neither utilizes advanced panel technology like LTPO, the Poco M4 Pro’s higher peak brightness makes it the clear winner for users who frequently consume content in bright environments.

Camera Comparison

Both phones feature 'Photo / Video' capabilities, but detailed sensor information is lacking. Without specifics, it’s difficult to make a definitive judgment. However, the market segment suggests both will rely on primary sensors around the 50MP mark. The absence of details regarding Optical Image Stabilization (OIS) or lens apertures makes a detailed comparison impossible. We can assume both will include standard 2MP macro/depth sensors, which offer limited practical value.

Performance

The Realme 9i’s Qualcomm Snapdragon 680 (6nm) focuses on efficiency with its octa-core configuration (4x2.4 GHz Kryo 265 Gold & 4x1.9 GHz Kryo 265 Silver). The Poco M4 Pro’s MediaTek Helio G96 (12nm) prioritizes performance with its octa-core setup (2x2.05 GHz Cortex-A76 & 6x2.0 GHz Cortex-A55). The 6nm process of the Snapdragon 680 should translate to better thermal management and power efficiency, but the Helio G96’s Cortex-A76 cores offer a slight advantage in CPU-intensive tasks. The larger process node of the Helio G96 may lead to more noticeable throttling under sustained load.

Battery Life

Both the Realme 9i and Poco M4 Pro achieve an endurance rating of 126 hours, suggesting comparable real-world battery life. However, the Poco M4 Pro’s 33W charging with PD3.0 and QC3 support allows for a full charge in 58 minutes, while the Realme 9i takes 70 minutes. This 12-minute difference, while not massive, provides a convenience advantage to the Poco M4 Pro. The efficiency of the Snapdragon 680 in the Realme 9i may partially offset the slightly slower charging speed.

Buying Guide

Buy the Realme 9i if you prioritize long-term software support and a consistently smooth, if not blazing-fast, experience. Its Snapdragon 680 chipset is known for its stability. Buy the Xiaomi Poco M4 Pro if you value a brighter, more vibrant display for media consumption and a slightly quicker charging time, and are comfortable with Xiaomi’s MIUI software.

Frequently Asked Questions

❓ Does the MediaTek Helio G96 in the Poco M4 Pro get noticeably hot during extended gaming sessions?
The Helio G96, built on a 12nm process, is more prone to thermal throttling than the Snapdragon 680’s 6nm process. While it offers a performance edge, expect some heat buildup and potential frame rate drops during prolonged gaming. The Poco M4 Pro’s thermal design will mitigate this, but it’s a factor to consider.
❓ Is the 33W charging on either phone truly 'fast charging' compared to other devices?
33W charging is considered moderate fast charging in 2024. While it’s faster than standard 15W or 18W charging, it’s significantly slower than the 65W or 120W charging found on higher-end devices. The Poco M4 Pro’s support for PD3.0 and QC3 ensures compatibility with a wider range of chargers.
❓ How does Xiaomi's MIUI software compare to Realme UI in terms of bloatware and updates?
MIUI is known for including more pre-installed apps (bloatware) than Realme UI. However, Xiaomi has been improving in this area. Realme UI generally offers a cleaner experience and a reputation for faster software updates, though both brands have varying update schedules depending on the region.
