Xiaomi Redmi 9 review: specs, battery & used prices
Hands-on-style overview of the Xiaomi Redmi 9 with MediaTek Helio G80: screen, cameras, battery, performance and what it costs used.
Summary
The Xiaomi Redmi 9 is a 2020 entry phone on the MediaTek Helio G80, with a 6.53-inch 60 Hz IPS panel, a 5020 mAh battery with 18 W charging, and a 198-gram body. Our catalog scores it 81 on compactness, with the 3/32 GB trim listed new near $130 and a single used example around $100. A 13-megapixel main camera is joined by an 8-megapixel ultrawide and a 5-megapixel auxiliary module. The Xiaomi Redmi 13C is the later entry model, and the Xiaomi Redmi 15 4G continues the entry line.
Display and design
The 6.53-inch IPS panel refreshes at 60 Hz with peak brightness listed at 400 nits in our records, baseline for the entry class of the year. The 198-gram body uses plain plastic with the era's circular camera block, and the build is honest rather than refined. Our compactness score of 81 marks ordinary large-phone proportions; our records list no ingress rating.
Performance
The Helio G80 earns an everyday axis of 26 and a gaming axis of 0 in our model: messaging, calls and light apps are the working envelope, heavier apps load slowly, and 3D gaming stays at puzzle level. Tracked trims span 3 to 6 GB of RAM, and the 4 GB trims are the sensible choice given the platform. Our records do not list a software window for this model.
Camera
A 13-megapixel main sensor leads a quad-style rear array, joined by an 8-megapixel ultrawide and a 5-megapixel auxiliary module, without optical stabilization, and our records track no video ceiling for this model. The camera axis of 14 is entry-level: the versatile four-lens layout was the selling point at the price, while detail and low light are basic. Documentation-grade photography.
Battery and charging
The 5020 mAh battery scores 40 on our battery axis, a full day easily and often two at light use, and the 18 W charger scores 0 in our records, meaning multi-hour refills. Endurance is the reliable strength of the package; refill speed is the entry-class compromise. Overnight charging is the practical habit.
Verdict
The Redmi 9 is the four-camera entry phone of 2020 at about $100 used per our single tracked listing: a big screen, a two-day battery and an unusually versatile lens layout for the price. The 60 Hz panel, the entry platform and the undocumented update horizon are the limits. It suits light users and secondary duty, with the Redmi 13C as the newer entry point of the family.
