Infinix Smart 9 Review: Budget Phone with Smooth Display and Surprising Features



In a market where budget smartphones often feel like a compromise, the Infinix Smart 9 tries to flip the narrative. At first glance, it's sleek, comes in fun colors, and even offers a 120Hz refresh rate something we rarely see in this price range.

But does the real life experience match the marketing promise? Let’s dive into what this affordable smartphone brings to the table and where it falls a bit short.

A Display That Outshines Its Price Tag

When you first pick up the Infinix Smart 9, the 6.7 inch HD+ display grabs your attention right away. It’s not just big it’s also surprisingly smooth, thanks to the 120Hz refresh rate. Scrolling through social media feels more fluid than you’d expect at this price.

Yes, the resolution caps at 720 × 1600 pixels, so don’t expect razor sharp images, but for day to day tasks like browsing, watching videos, or replying to messages, the screen delivers more than enough clarity.

And with a 240Hz touch sampling rate, it responds swiftly ideal for casual gamers and fast texters alike.

Powered for Everyday Use

Under the hood, the Smart 9 is powered by the MediaTek Helio G81 chipset, paired with 3GB or 4GB of RAM (plus up to 4GB virtual RAM). While this setup won’t rival high end phones, it's capable enough for essential tasks think YouTube, WhatsApp, Instagram, and even light gaming.

The phone runs Android 14 Go Edition, a lighter version of the OS designed to be faster on low spec devices. And it shows apps launch fairly quickly, and system animations are smooth.

One trade off, though: some full apps may not be compatible with Android Go, and multitasking has its limits.

All Day Battery With Fast Charging

One of the strongest features of the Infinix Smart 9 is its 5000mAh battery. Whether you're streaming, scrolling, or just keeping up with messages, the phone comfortably lasts a full day or even two with moderate use.

Charging isn’t lightning fast, but it does support 18W XCharge via USB-C, which is a nice touch at this price point.

Cameras: Basic But Capable

The Smart 9 comes with a 13MP rear camera and an 8MP front facing shooter, both equipped with dual LED flash. For quick social media snaps or video calls, it performs reasonably well, especially in good lighting.

No, you won’t get pro level portrait shots or crisp night photography, but for a budget phone, it holds its own. Video recording maxes out at 1080p, and that’s more than enough for casual use.

Extras That Add Value

Despite its price, the Infinix Smart 9 doesn’t skimp on the little things:
  • Side mounted fingerprint sensor for fast unlocking
  • 3.5mm headphone jack (yes, it's still useful)
  • Dedicated microSD card slot (expandable up to 2TB)
  • FM Radio for offline entertainment
  • Dual SIM support
  • Bluetooth 5.0, and splash resistance (IP54)
For users upgrading from older phones or looking for a reliable secondary device, these additions make a big difference.

Real World Performance: What Users Are Saying

Early user reviews are mostly positive, especially praising the phone’s battery life, smooth display, and clean interface. However, some common concerns include:
  • Sluggish performance when switching between apps or running games like Genshin Impact
  • Call quality issues a few users noted the microphone volume can be weak
  • Limited internal performance over time, especially with heavier use

In short: it’s a phone that performs well within its lane but doesn’t pretend to be more than it is.

Alternatives Worth Considering

If you're willing to stretch your budget a bit, you might want to consider:
  • Infinix Hot 50 Pro – for slightly better gaming performance
  • Redmi A3 or Note 13 – for a stronger app ecosystem and regular updates
  • realme Narzo series – good blend of style and battery life
Still, for under $100–$120 (depending on market), the Infinix Smart 9 is hard to beat in terms of features.

Final Verdict: Should You Buy the Infinix Smart 9?

If you're looking for a basic smartphone with modern touches, the Infinix Smart 9 hits the sweet spot. The smooth display, long battery life, and Android Go optimizations make it a solid option for students, first time smartphone users, or anyone who needs a reliable backup device.

Just don’t expect it to handle heavy gaming or advanced multitasking like a champ.
