About the Xiaomi Redmi Note 9 5G

The Redmi Note 9 5G is the Chinese-market model Xiaomi launched in late 2020 to bring 5G to its cheapest Redmi Note, and it is worth knowing exactly what that means before buying one in the UK. The same MediaTek Dimensity 800U chip, 6.53-inch 1080p LCD, 5,000mAh battery and 48MP main camera were sold in Europe as the Redmi Note 9T, but the two are not identical. This Chinese model has an 8MP ultrawide camera the 9T lacks, yet it has no NFC for contactless payments and does not support 4G band 20, the 800MHz frequency UK networks use for indoor and rural coverage. The basics are sound for an old budget phone: the battery comfortably lasts a day, and there is a headphone jack, a dedicated microSD slot, stereo speakers and an infrared blaster. The screen is a standard LCD without a high refresh rate, charging is a slow 18W, and at 199g it is heavy. It launched on Android 10, and its European twin is already on Xiaomi's official end-of-support list. For a UK buyer it only makes sense as a cheap spare.

Frequently asked questions

Is the Xiaomi Redmi Note 9 5G worth buying?

Only as a cheap spare, and only once you know which version you are getting. The Chinese Redmi Note 9 5G has no NFC and lacks the 800MHz 4G band UK networks rely on for coverage, and its European twin is already on Xiaomi's end-of-support list. The European Redmi Note 9T shares its chip and battery and suits the UK better, while a current model such as the Redmi Note 15 is the better buy for a main phone.

Is the Xiaomi Redmi Note 9 5G the same as the Redmi Note 9T?

They are close but not identical. Both use the Dimensity 800U, a 6.53-inch 1080p LCD, a 5,000mAh battery with 18W charging and a 48MP main camera. The Chinese Redmi Note 9 5G has an 8MP ultrawide camera where the 9T has only a depth sensor, but the European Redmi Note 9T adds NFC and supports the 800MHz 4G band that UK networks use.

Will the Xiaomi Redmi Note 9 5G work in the UK?

It will connect, but with limits. The Chinese model supports 5G on the n78 band that carries most UK 5G and common 4G bands such as 3 and 7, but not 4G band 20 at 800MHz, which UK networks use for indoor and rural coverage, so signal may be weaker in some places. It also has no NFC, so it cannot be used for contactless payments.

Does the Xiaomi Redmi Note 9 5G still get software updates?

Treat it as unsupported. It launched in late 2020 running Android 10 with MIUI 12, Xiaomi's general policy only commits to security updates for at least two years after a model first ships, and its European twin, the Redmi Note 9T, is on Xiaomi's official end-of-support list. That makes it a poor choice as a main phone for banking and payments.

Does the Xiaomi Redmi Note 9 5G have a headphone jack and microSD slot?

Yes to both. There is a 3.5mm headphone jack and a dedicated microSD slot, so you can add storage without giving up the second SIM. It also has stereo speakers and an infrared blaster for controlling a TV.

Should I buy the Xiaomi Redmi Note 9 5G or the Redmi Note 15?

The Redmi Note 15 is ahead in every area that matters day to day: a faster Snapdragon 6 Gen 3, a 6.77-inch 120Hz AMOLED screen, a 108MP stabilised main camera, a 5,520mAh battery with 45W charging, IP66 dust and water resistance and a launch promise of up to four major Android updates. It is also lighter at 178g against 199g. The Redmi Note 9 5G's only advantages are a headphone jack and a dedicated microSD slot, so it only makes sense if price is the deciding factor.

Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. 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. Where DXOMARK has lab-tested the phone, its measured score replaces this estimate.

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.
