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 Infinix Note 40, which lacks published brightness data. While both likely utilize similar LCD or AMOLED panels (market segment suggests AMOLED for the Redmi), the Redmi’s higher peak brightness translates to a superior viewing experience in direct sunlight. Bezels are expected to be comparable, given the similar price points, but color accuracy data is unavailable for either device, making a definitive judgment impossible.
Camera Comparison
Detailed camera specifications are limited, but both phones are expected to feature multi-camera systems. The Redmi Note 13 Pro 4G likely benefits from Xiaomi’s established image processing algorithms, potentially delivering more refined photos. Without sensor size or aperture information, it’s difficult to assess low-light performance. The presence of a 2MP macro camera on both devices is largely a marketing tactic, offering limited practical value due to the small sensor size and low resolution. Focus should be on the main camera performance, which remains largely unknown.
Performance
Both the Infinix Note 40 and Xiaomi Redmi Note 13 Pro 4G are powered by the MediaTek Helio G99 Ultra chipset, featuring an identical CPU configuration: an octa-core setup with 2x2.2 GHz Cortex-A76 cores and 6x2.0 GHz Cortex-A55 cores. This means CPU performance will be virtually indistinguishable between the two. The real-world performance difference will likely hinge on RAM configuration (not specified) and thermal management, which is unknown for both devices. The G99 Ultra’s efficiency is good for its class, but sustained gaming will likely result in some throttling.
Battery Life
The Redmi Note 13 Pro 4G demonstrates a clear advantage in charging speed, achieving a 50% charge in just 16 minutes and a full charge in 46 minutes with its 67W wired charging. The Infinix Note 40, with its 45W wired charging, takes 26 minutes to reach 50%. The Redmi Note 13 Pro 4G also boasts a strong active use battery score of 11:36h, suggesting excellent battery life. The Infinix Note 40 counters with 20W MagCharge wireless charging and reverse charging capabilities, offering flexibility for users invested in the wireless charging ecosystem.
Buying Guide
Buy the Infinix Note 40 if you heavily value wireless charging convenience and the MagCharge ecosystem, potentially owning other compatible accessories. Buy the Xiaomi Redmi Note 13 Pro 4G if you prioritize faster wired charging speeds, a brighter and more visible display in outdoor conditions, and longer sustained battery life during active use.
