Editorial report
Xiaomi Redmi Note 9 4G 4 GB / 128 GB / China technical sheet
The Xiaomi Redmi Note 9 4G suits buyers who put battery capacity first and can accept a dim display capped at 60 Hz. Its 6000 mAh battery capacity is among the highest for phones launched around the same time, while 18 W fast charging is average. Reverse charging is also included.
The 6.53-inch IPS LCD display has a 1080 × 2340 px resolution and 395 ppi pixel density, slightly above average. Its 400 nits of brightness and 60 Hz refresh rate are weak points among phones of its time. Performance is also below average: the Snapdragon 662 records 184,000 in AnTuTu v8. This configuration has 4 GB of RAM and 128 GB of storage; the Redmi Note 9 4G is also sold with 6 GB or 8 GB of RAM and 128 GB of storage.
The camera setup is better than that of most phones launched around the same time. A 48 MP main camera is joined by an 8 MP ultrawide and a 2 MP depth camera. Connectivity, by contrast, is below average. With a NeoScore of 5.0, this is a phone for buyers who value battery capacity more than the display and performance.
