Xiaomi Redmi Note 9 Pro: Cheap mid-range smartphone with a 5020-mAh battery
The mid-range smartphone Xiaomi Redmi Note 9 Pro offers an exciting price-performance ratio. For 250 Euros (~$282), buyers receive a phone with a 6.67-inch IPS display, 6 GB of RAM, 64 or 128 GB of internal storage, the octa-core Qualcomm Snapdragon 720G SoC and 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.
My fascination for computers started with the C64. Since then, I’ve put everything that comes my way in terms of hardware through its paces. From the C64 to the Amiga 500 and the first PC with an 8088 CPU, my list of projects has grown increasingly longer. For more than 20 years now I have also turned my hobby into my profession and have been active in the mobile section of Notebookcheck since 2021. Before that, I worked as a hardware editor for IDG Media (tecChannel.de) and VNU Business Publications (PC professional), among others.

Even in my youth I was already very enthusiastic about technology, and as a result I started building PCs, optimizing them, and writing programs while I was still in school. When dealing with the inevitable hardware and software problems associated with computers, I was always relentless in my search for the necessary solutions. The compact forms of laptops and smartphones introduced further challenges in this regard. In my reviews for Notebookcheck I try to communicate as objectively as possible how well a device copes with these hurdles.
