Xiaomi Redmi Note 9 Pro: Cheap mid-range smartphone with a 5020-mAh battery

With a capacity of 5020 mAh, the battery of the Xiaomi Redmi Note 9 Pro is decidedly large and unmatched in size by most current smartphones. However, Redmi's own Note 9S contains the same battery, making it a competitor in this aspect.

The Redmi Note 9 Pro shows a seemingly unlimited amount of stamina in our reivew. With almost 20 hours, the smartphone reaches an excellent runtime in our Wi-Fi test (display brightness set to 150 nits, loading a web page every 30 seconds). When playing a H.264 video, it lasts fairly long as well. Even under maximum load, it still achieves almost 5 hours of battery life. This should translate to real-world runtimes of at least one day or even multiple days.

This may fill those who have already purchased its sibling Redmi Note 9S with regret. While the Redmi Note 9 Pro is physically almost identical, it offers a few higher-end features for a rather small premium. The main differences: 6 GB of RAM regardless of the storage configuration, a 64-MP instead of a 48-MP camera, a more powerful quick charger (33 watts vs. 22.5 watts) and, perhaps the most important difference, an NFC module.
