Infinix Note 50x 5G+ review: Gets the basics right

Rating: 3.5/5


Infinix Note 50x 5G+ is one of its latest additions to the brand’s Note 50 series and is a contender in the affordable mid-range smartphone category. The phone, which succeeds last year’s Infinix Note 40x, comes in a 6 GB + 128 GB version that starts at Rs 11,499, while the 8 GB + 128 GB variant is available for Rs 12,999 on Flipkart. The company claims this to be the first phone to come powered by MediaTek’s Dimensity 7300 Ultimate chipset, as the device aims to provide strong performance for both gaming and seamless multitasking.



The Note 50x also features hardware that looks capable on paper to stand up to the claim. This includes a 6.67-inch HD+ display with a 120 Hz refresh rate for smooth visuals, complemented by a 5,500 mAh battery, paired with 45W fast charging. The phone also promises an improved software experience with smoother navigation and better animations in the new XOS 15.

But can the smartphone persist through challenges in real-life situations? We have put the X variant of Note 50x in Titanium Grey colour to the test in various situations over the days, and here’s what we think about the phone:


Design and display

The Infinix Note 50x greets you with a matte-finish rear panel that feels surprisingly premium in hand, thanks to its special coating. The rectangular camera module (which the company calls Gem Cut) sits flush with the back, creating minimal wobble when placed on a table—something that we noticed while tapping its screen on the desk.


At just under 200 grams and bearing an IP64 dust- and splash-resistance rating plus MIL-STD-810H certification, it strikes a smart balance between sturdiness and comfort.

On the right edge, you’ll find the power button (which doubles as a snappy side-mounted fingerprint sensor) and volume rocker, while the SIM tray, USB-C charging port and speaker grille sits on at the bottom.


Flip it around and you’re met with a 6.67-inch HD+ IPS display running at a 120 Hz refresh rate. Colours look vibrant indoors, and the Ultra Touch mode boosted responsiveness when we frantically tapped through my morning news feed.

The phone’s peak brightness is good enough that we could still make out navigation prompts under harsh midday sun, though fine text and UI elements do appear a bit soft at this resolution.


Despite the 720p resolution, when we binge-watched Game of Thrones during a long flight, the visuals remained immersive; only the tiniest text in the end credits appeared fuzzy. Playing BGMI on the phone proved smooth: the display captured the smallest gestures, and the movements stayed crisp.


Performance and gaming

Under the hood sits MediaTek’s Dimensity 7300 Ultimate chipset paired with up to 8 GB of LPDDR4X RAM and 128 GB of UFS 2.2 storage. Everyday tasks—from scrolling through social feeds to juggling multiple browser tabs—were handled effortlessly. On a recent road trip, we were able to edit photos, stream music, and hop between messaging apps without any noticeable slowdown.


When it comes to gaming, the Note 50x truly shines for its class. Battling it out in BGMI at medium settings felt smooth, with frame rates holding steady even in heated gunfights. We even squeezed in a quick Call of Duty: Mobile session during a long train ride—graphics stayed crisp and input lag was minimal, though the phone did grow slightly warm after about half an hour. For gamers on a budget, the Note 50x delivers reliable, responsive performance well beyond its price tag.

The Infinix Note 50x runs Android 15-based XOS 15 skin, with just a handful of pre-installed apps that can be ditched if not required. The result is a clean, fluid UI that never feels bogged down, and Infinix backs it with two years of OS updates plus three years of security patches.


The Note 50x’s AI suite in XOS 15 adds genuine everyday value without feeling gimmicky. The Gallery’s AI Cutout tool allowed us to long-press on a photo of a dining table to isolate and share a picture of a morning espresso in seconds—no manual cropping needed—and the Text Extract feature pulled ingredients straight from a receipt snap for easy grocery list creation.


During a cross-country video call, we tested Live Call Translation between English and Hindi in WhatsApp—while not flawless, it smoothed over language gaps when discussing dinner plans with family. Google’s Circle to Search tool also shines on the Note 50x: circle-selecting a restaurant logo in a screenshot pulled up reviews instantly.



Other handy tools include the Dynamic Bar for quick shortcuts, an AI-powered Wallpaper Generator that matches our home-screen aesthetic, and Smart Translation gestures for on-the-fly text conversion. Together, these features made the Note 50x feel smarter with every tap.

Camera
The Infinix Note 50x sports a 50 MP AI primary sensor alongside a 2 MP depth lens. The camera app is straightforward, with key modes—Photo, Video, Night, Portrait—easily accessible on the viewfinder.



In bright daylight, the main camera delivers crisp shots with balanced colours and good dynamic range. We tested this by capturing a sunset over our office building; the subtle gradient and reflections held up beautifully. Digital zoom up to 2x retains reasonable clarity, but pushing beyond that softens details and blurs edges.

When ambient light falls, Night mode kicks in automatically. While taking photos at night, we found images adequately exposed but were marked by noticeable noise and a slight loss of fine texture.

The Note 50x handles portraits decently. As we snapped a friend in front of a leafy wall and the subject-background separation was generally accurate, though stray hairs were occasionally blurred.

Here are some camera samples:







The 8MP front camera also produces natural-looking selfies in daylight. We took one under neon club lights—colours were vivid, but as the lighting dropped, grain appeared in shadow areas.

The Infinix Note 50x’s video suite is surprisingly versatile for its class. With the rear camera, we were able to shoot up to 4K at 30 fps or dial down to 1080p with high-frame-rate options of 120 fps and 240 fps for smooth slow-mo clips. Resolution and frame-rate toggles are right in the viewfinder, so we were able to switch on the fly.

In bright conditions, 4K footage is crisp with natural colours—we filmed fireworks in 4K, and each spark shimmered vividly. The 1080p@240 fps mode allowed us to capture our ultra-slow detail, good enough for sharing on social media.

The 8MP front-facing camera records at up to 1440 p@30 fps (or 1080 p@30 fps), making it handy for vlogging. During a video call at a rooftop café, our faces stayed clear even against the sky’s glare.

Low-light video holds up decently at 1080p, though noise creeps in once the sun goes down, and the output gets a bit grainy. Digital stabilisation does a decent job of smoothing handheld pans, though rapid moves introduce slight judder.

Battery

As far as battery is concerned, the Infinix Note 50x houses a 5,500 mAh cell—500 mAh more than its predecessor—ensuring we easily made it through a full day of 5G browsing, BGMI sessions, and video calls with around 25 per cent left by bedtime. On a recent weekend road trip, we streamed Avengers: Endgame on the highway’s shaky network and still had juice to spare for late-night messages.

Charging is fast thanks to the 45 W wired charger: a flat battery reached 100% in roughly 40 minutes. We once topped up to 50% during breakfast in just 15 minutes, and it was enough to power us through the morning commute.

The inclusion of bypass charging keeps the device cooler under heavy gaming loads, while 10W reverse charging allows us to lend power to the earbuds when needed.


Verdict

At a price under Rs 15,000, the Infinix Note 50x delivers a sturdy, splash-resistant design with MIL-STD-810H certification and an IP64 rating. Its 6.67-inch HD+ 120 Hz display ensures smooth scrolling, even if finer details lack the sharpness of higher-res screens.

Under the hood, the MediaTek Dimensity 7300 Ultimate chipset and up to 8 GB of RAM handle daily tasks and casual gaming with ease. A 5,500 mAh battery paired with 45 W fast charging—and bypass charging for cooler gaming—easily lasts a full day. XOS 15’s AI features add thoughtful conveniences without weighing down the UI.

Daylight camera performance is reliable, though low-light shots and the HD resolution are minor compromises. Overall, the Note 50x is a well-rounded budget contender that balances performance, battery life, and useful extras for value-minded users.
