Xiaomi Redmi Note 14 4G review

HyperOS + Android 14

The Redmi Note 14 4G runs on HyperOS based on Android 14 - a combination we've already seen numerous times on current Xiaomi phones and unfortunately, only a handful of those newly released devices run on the latest Android 15 version with HyperOS 2.0 even though Android 15 came around in early Q4 last year.

Surprisingly, Xiaomi promises 4 major OS updates and 6 years of software patches, meaning twice as many major OS upgrades compared to the 5G version. That's quite generous for a low-end device, even though it's launching one version late for the Western markets.

We've already reviewed this specific HyperOS 1.0 + Android 14 combo in a dedicated article, so we suggest you check that one out. Keep in mind that some higher-end features are not available on this Redmi.

In addition to the already-known features, the incremental HyperOS 1.02 upgrade brings some AI-powered features, which aren't all available right away and are expected to come soon via an OTA update.

The features available on the Redmi Note 14 5G and 14 4G are AI Erase, AI Sky and AI Beautify - all Gallery-related functionalities. The phone also supports Google's Gemini AI and all of its plugins that should work with select apps.

In contrast, the Pro and Pro+ models also offer Circle to Search on top of the above features. The Pro+ even has AI Interpreter, AI Notes, AI Recorder, AI Subtitles and AI Film.

It's perhaps noteworthy that we found quite a bit of ads in system apps, even in Europe. You can disable them for each app, but it's rather annoying and takes time.

Benchmark performance

The Redmi Note 14 4G runs on a Helio G99 Ultra based on TSMC's 6nm manufacturing process. This is probably the fifth iteration, or refresh, of the same Helio G99 SoC, but we struggle to decode what the "Ultra" designation stands for. It's practically the same chipset as before.

From what we can tell from a combination of spec sheets and the review unit, the Helio G99 Ultra still uses a 6nm TSMC manufacturing process. It is also still rocking two ARM Cortex-A76 "big" cores, clocked at up to 2.2GHz and another six "small" Cortex-A55 CPU cores, working at up to 2.0 GHz. Nothing has seemingly been hanged on the GPU front either, where the chipset gets a modest Mali-G57 MC2 GPU.

The Redmi Note 14 4G comes in 6/128GB, 8/128GB, and 8/256GB storage trims, all of which use UFS 2.2 type of storage. Our review unit is the highest 8/256GB tier.

As you can see, the Redmi Note 14 4G with its Helio G99 Ultra isn't the best performer in its class. Still, it shows a significant improvement in overall performance compared to its predecessor.

Sustained performance

It's perhaps no surprise that the Redmi Note 14 4G can keep the Helio G99's CPU running at almost 100% for long periods without any thermal throttling as the chipset itself isn't very demanding.
