About the Xiaomi Redmi Note 9

The Redmi Note 9 was built around one idea: give budget buyers a battery that simply does not run out. The 5,020mAh cell paired with a modest MediaTek Helio G85 chip means two days of light use is realistic, and that endurance is still the main reason anyone picks one up today. Xiaomi also kept the practical extras that disappeared from more expensive phones years ago, including a 3.5mm headphone jack, a microSD slot for cheap storage expansion and an infrared blaster for controlling a TV. The screen is a 6.53-inch LCD rather than AMOLED, so blacks look grey next to a Samsung A-series rival, and at 199g the phone is chunky. The 48MP main camera is fine in daylight and struggles once the light drops, with the 2MP macro and depth sensors adding almost nothing. It is a 4G-only phone, launched on Android 10 with MIUI 11 and reached Android 12 before support ended, so it is now best suited to a first phone, a work handset or a spare.

Frequently asked questions

Is the Xiaomi Redmi Note 9 worth buying?
It is worth considering as a cheap, long-lasting backup or first phone. The 5,020mAh battery is its standout feature and the headphone jack and microSD slot are genuinely useful. But it is 4G only, the LCD screen and camera are basic, and it no longer receives Android or security updates.
Does the Xiaomi Redmi Note 9 support 5G?
No. The standard Redmi Note 9 with the Helio G85 is a 4G-only phone. Xiaomi sold separate Redmi Note 9 5G and Redmi Note 9 Pro 5G models later in 2020 if 5G matters to you.
How long does the Xiaomi Redmi Note 9 battery last?
The 5,020mAh battery is the phone's strongest feature and will comfortably clear a full day, often stretching into a second on light use, helped by the power-efficient Helio G85 and the 1080p LCD screen. It charges at up to 18W, which is slow by modern standards.
How does the Xiaomi Redmi Note 9 compare to the Redmi Note 9 Pro?
The Pro is the meaningful step up. It swaps the Helio G85 for a faster Snapdragon 720G, upgrades the main camera from 48MP to 64MP, moves to a larger 6.67-inch screen and charges at 30W instead of 18W. Both share the same 5,020mAh battery.
Does the Xiaomi Redmi Note 9 have a headphone jack and microSD slot?
Yes to both. There is a 3.5mm headphone jack and a microSDXC card slot that supports cards up to 256GB, so you can add storage cheaply. It also has an infrared blaster for controlling a TV or set-top box.
How good is the Xiaomi Redmi Note 9 camera?
Acceptable in good light and weak in anything else. The 48MP main sensor produces usable daylight photos and the 8MP ultrawide is fine for landscapes, but the 2MP macro and 2MP depth sensors contribute little and low-light shots are noisy.

Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
