Xiaomi Redmi Note 9S review: specs, battery & used prices

Summary

The Xiaomi Redmi Note 9S is the 2020 large-format mid-ranger of the Note 9 family, running the Snapdragon 720G with a 6.67-inch 60 Hz IPS panel and a 5020 mAh battery in a 210-gram body. Our catalog scores it 31 on everyday use, 74 on compactness and 20 on screen. A 48-megapixel main camera records 4K30 video, and the 4/64 GB trim was tracked at about $200 new. The Redmi Note 9 is the global base, and the Redmi Note 9 Pro the camera upgrade.

Display and design

The 6.67-inch IPS panel runs at 60 Hz and scores 20 on our screen axis, with a 628-nit figure that is genuinely bright for the class. No ingress rating is documented. At 210 grams the body earns the compactness score of 74 — a large, heavy slab even for 2020, the price of the big cell and big screen.

Performance

The Snapdragon 720G posts an everyday axis of 31 and a gaming axis of 4: solid mid-range pace that aged gracefully, with casual gaming comfortable and demanding titles outside reach. Tracked trims run from 4 to 6 GB of RAM, and no software-window figure is documented for this model.

Camera

The camera axis of 29 rests on a 48-megapixel main sensor with supporting companion sensors, recording 4K30 video. Daylight detail from the main sensor was class-appropriate and consistent; the companions are framing-only, and night shots stay at the bracket's floor.

Battery and charging

The 5020 mAh battery scores 40 on our battery axis — two days at mid-range pace were realistic — while 18 W charging scores 0, the slow refill that became the family's standard compromise. Endurance first; patience at the outlet second.

Verdict

At about $200 new for 4/64 GB, the Redmi Note 9S packed a 628-nit screen, a 5020 mAh cell and reliable mid-range pace into an unmistakably large frame. Used market data is sparse. The Note 9 trims the size, and the Note 9 Pro adds the higher-resolution camera and faster refill.
