Infinix Note 50 Pro 4G review

Android 15 with XOS 15

The Note 50 Pro 4G runs Android 15 with Infinix's XOS (also v15) layered on top. The company isn't particularly generous with its software support promises, but it has committed to 2 OS upgrades and 3 years of security updates, which is probably enough for most potential owners.

The fundamentals of the UI aren't too different from competing Android overlays, so there won't be any major adjustments needed.

That said, there's an extra twist to the Large folder implementation that we don't remember seeing before - you can have it in a 1x3 icon form factor in addition to the usual 3x3. We asked around, and at least one person at the office found that useful.

The Note 50 Pro is packed with AI features and just listing them would take a while. It's nice then that there's an Infinix AI menu item in settings where they're all neatly organized. Each feature is detailed, and there are tutorials for most of them right there.

There's an in-house system-wide assistant called Folax, now closely integrated with DeepSeek R1. You can easily switch that to Google Gemini (or alternate between the two if you're into that).

AI stuff

There's text recognition and extraction, audio recording and call summary and translation, wallpaper generation, document assistance (summary, translation, generation) - pretty much everything you can think of. There's also Circle to search, of course.

More AI stuff

The phone allows you to flip a toggle, download the AI model for most of these things and have the processing done on-device. If you're worried about your data going back and forth to the cloud, maybe that's your toggle.

Yet more AI stuff

You can use Ai in the gallery for subject extraction or object eraser, of course.

With all those AI capabilities on board, you'd think that there would be a bunch of image editing functionality as well, but there's little beyond basic AI object erasing - no reflection removal, or sky enhancement, or anything else.

There's also a quick menu for controlling the Active Halo lighting. You can use it for notifications, charging progress or timer indication, among other things.

The heart rate and blood oxygen level sensor inside the halo, meanwhile, can be used for keeping track on your vitals.

Welife is the app that utilizes the IR emitter. And Health is where you can use the onboard heart-rate/SpO2 sensor.

Performance and benchmarks

The Infinix Note 50 Pro 4G utilizes the Helio G100 Ultimate chipset (6nm). It contains an octa-core processor with 2x2.2 GHz Cortex-A76 & 6x2.0 GHz Cortex-A55 and the Mali-G57 MC2 GPU. The phone is available in two configurations with LPDDR4X + UFS2.2 storage - 8GB + 256GB and 12GB + 256GB (ours).

This SoC offers the same processor as the Note 40 Pro's Dimensity 7020, but the GPU here should be more powerful. On the other hand, the Dimensity 7020 has a 5G modem, while the new Note 50 Pro maxes out at 4G connectivity.

And now, let's see some benchmark scores.

Unfortunately, the scores of the Note 50 Pro 4G are uninspiring. The phone matches the performance of the most current Redmi Note 14 Pro 4G, which uses the same chipset, which is not an achievement to brag with.

The Infinix Note 50 Pro 4G is trailing behind the competition even of it offers adequate performance and smooth UI experience even at 144Hz refresh rate. It can do basic gaming, but that's it. AI tasks run well, too, but they do take at least 15 seconds.

On a positive note, there is no CPU or GPU throttling happening even after long stress tests, which is good.
