Is this the ultimate budget endurance champion? We dive deep into the Realme Narzo 90X to see if it lives up to the hype.
In the crowded world of budget smartphones, standing out is tough. Manufacturers often juggle between performance, battery, and display quality, usually dropping the ball on one to save costs on the other. Enter the Realme Narzo 90X, a device that seems to have thrown caution to the wind by packing a massive 7000mAh battery and a buttery-smooth 144Hz display into an affordable package.
Designed for the power user on a budget, this phone promises to keep you connected, entertained, and gaming for longer than almost anything else in its class. But does the real-world experience match the impressive spec sheet? Let’s find out in this in-depth review.

Before we get into the nitty-gritty, here is a quick snapshot of what makes this phone tick and where it might fall short.
| The Good | The Not-So-Good |
|---|---|
| ✅ Massive 7000mAh Battery | ❌ No NFC Support |
| ✅ Ultra-smooth 144Hz Refresh Rate | ❌ HD+ Resolution (not FHD+) |
| ✅ IP68/IP69 Dust & Water Resistance | ❌ Mono Speaker |
| ✅ Fast Charging included | ❌ Low-light camera struggles |
Realme has a reputation for being generous with their box contents, and the Narzo 90X is no exception. In an era where flagship phones are ditching chargers, Realme includes everything you need to get started.
What’s in the box:
It’s refreshing to unbox a phone and not have to immediately hunt for a charging brick. The included case is a nice touch, ensuring your new investment is protected from day one.

When you hold the Narzo 90X, the first thing you notice is its solid build. Available in Flash Blue and Nitro Blue, the design borrows cues from premium devices. We tested the Flash Blue variant, and the faux leather-like finish on the back is fantastic. It not only looks premium but also provides a great grip and resists fingerprints—a common annoyance with glossy plastic backs.
Despite housing a gargantuan battery, the phone maintains a manageable profile at 8.28mm thickness, though it does weigh 212 grams. It feels substantial but not overly heavy.
One of the standout features here is the IP68/IP69 rating. This level of dust and water resistance is virtually unheard of in this price segment. Whether it’s a splash of rain or an accidental drop in the sink, the Narzo 90X is built to survive.

The display is where Realme made a clear choice: speed. The phone sports a massive 6.8-inch IPS LCD panel with a jaw-dropping 144Hz refresh rate.
The Experience: Scrolling through social media feeds, browsing the web, and navigating the UI feels incredibly fluid. If you are coming from a standard 60Hz screen, this will feel like a massive upgrade. The peak brightness of 1,200 nits is excellent, making outdoor visibility a breeze.
The Trade-off: To achieve this refresh rate at this price point, the resolution is capped at HD+ (720 x 1570 pixels). While text and images are sharp enough for daily use, pixel peepers might miss the crispness of a Full HD+ panel. However, for gaming and video streaming, the sheer size and smoothness make up for it.

Under the hood, the Narzo 90X is powered by the MediaTek Dimensity 6300 5G chipset. Built on a 6nm process, this processor is designed to balance performance with power efficiency.
Paired with up to 8GB of RAM (plus virtual RAM expansion) and 128GB of storage, the phone handles multitasking with ease. Apps launch quickly, and switching between tasks is snappy, thanks in part to the optimized Realme UI 6.0 based on Android 15.
Gaming Test: Casual games like Subway Surfers or Candy Crush run flawlessly at high frame rates. For heavier titles like PUBG or Call of Duty Mobile, the Mali-G57 MC2 GPU holds its own at medium settings. You might notice some frame drops at max settings, but for a budget device, it performs admirably.
Benchmarks: The synthetic benchmarks back up our real-world findings.
With an AnTuTu score hovering around 458,821, it sits comfortably in the mid-range performance bracket, capable of handling everything the average user throws at it.

The camera module features a stylish circular design housing a 50MP primary sensor (f/1.8 aperture).
In good lighting, the main camera shines. Images are crisp, with natural colors that don’t look artificially oversaturated. The dynamic range is decent, handling shadows and highlights well for this segment.
As the sun goes down, the camera struggles a bit more. While the Night Mode helps to brighten up scenes, you will notice some noise and a loss of fine detail in darker areas. It’s perfectly usable for social media, but don’t expect flagship-level nightography.
Selfies: The 8MP front camera is adequate for video calls and casual selfies. The beauty mode smoothens skin textures effectively, though it can sometimes be a bit aggressive with the processing.

This is the main event. The 7,000mAh battery is simply monstrous.
Real-World Usage:
When you finally do run out of juice, the 60W fast charging gets you back in the game quickly, charging the massive cell to 100% in just over an hour. It even supports reverse wired charging, turning your phone into a power bank for your earbuds or other devices.

Q: Can I play PUBG/Free Fire on this phone? A: Absolutely. The Dimensity 6300 chipset and 144Hz screen provide a smooth gaming experience at medium to high settings.
Q: How long does the battery last? A: With a 7000mAh battery, you can expect nearly 2 days of moderate usage.
Q: Does it support 5G? A: Yes, the MediaTek Dimensity 6300 is a 5G-enabled chipset, ensuring you are future-proofed for high-speed networks.

If you prioritize battery life, durability, and smooth performance over having the sharpest screen or the best night camera, the Narzo 90X is an unbeatable choice in the budget segment.
