Realme Narzo 100x Vs Realme Narzo 90x? Here’s The One You Should Actually Buy

When two smartphones have the same processor, similar cameras, and nearly identical displays, choosing between them isn’t as simple as it seems. That’s exactly the case with the Realme Narzo 100x vs Realme Narzo 90x.

Instead of comparing every specification line by line, you should focus on the features that actually affect your daily experience. Do you need a phone that lasts longer on a single charge? Would faster charging save you more time? Or are you looking for the best value without overspending?

This comparison breaks down the key differences in a way that’s easy to understand, so you can confidently decide which Narzo smartphone deserves your money. Let’s get started.

Realme Narzo 100x Vs Realme Narzo 90x: Specs At A Glance

Looking at the table, it’s clear that Realme Narzo 100x vs Realme Narzo 90x have more similarities than differences. 

However, the differences they do have are meaningful enough to influence your buying decision.

Design And Display: You Won’t Notice Much Difference

If you’re expecting one phone to look significantly better than the other, you’ll probably be disappointed.

The Realme Narzo 100x sports a 6.81-inch HD+ IPS LCD, while the Narzo 90x features a 6.8-inch HD+ LCD. The size difference is so small that it’s practically impossible to notice during daily use.

Both displays also support a 144Hz refresh rate, which is one of the biggest highlights of the Realme Narzo 100x vs Realme Narzo 90x. Whether you’re scrolling through Instagram, switching between apps, or playing supported games, animations feel smoother than they do on a standard 60Hz display.

That said, both phones use an HD+ resolution (1570 × 720 pixels). If you’re upgrading from an older budget smartphone, the display will still feel smooth and enjoyable. However, if you’ve previously used a Full HD+ AMOLED panel, you’ll notice that text isn’t quite as sharp and colours aren’t as vibrant.

For streaming YouTube videos, browsing social media, reading articles, or casual gaming, both displays perform similarly. Since the refresh rate, screen size, and resolution are nearly identical, the display isn’t a deciding factor between these two smartphones.

Performance: The Same Chip Means The Same Experience

Many buyers assume that the newer phone in a lineup automatically performs better.

That’s not true here.

Both the Realme Narzo 100x vs Realme Narzo 90x run on the MediaTek Dimensity 6300, so you’re getting the same processing power regardless of which phone you choose.

In everyday use, you can expect smooth performance while browsing the web, watching videos, attending online classes, replying to messages, and switching between your favourite apps. Tasks like scrolling through social media, editing documents, or making video calls won’t feel any different on either device.

Gaming performance is also expected to remain almost identical. Since the chipset is the same, popular games should deliver similar frame rates and graphics settings on both phones.

In other words, if raw performance is your biggest concern, you don’t need to spend extra on one model over the other. The processor simply isn’t where these two phones differ.

RAM And Storage: Think About How You Use Your Phone

Although the processor remains unchanged, the memory configurations tell a different story.

The Realme Narzo 100x offers three variants:

• 4GB RAM + 128GB Storage
• 6GB RAM + 128GB Storage
• 6GB RAM + 256GB Storage

Meanwhile, the Narzo 90x comes with:

• 6GB RAM + 128GB Storage
• 8GB RAM + 128GB Storage

At first, you might think that the Narzo 90x is the better option because it offers an 8GB RAM model. But that isn’t necessarily true.

If your phone is filled with high-resolution photos, downloaded movies, offline music playlists, and large games, storage usually becomes a bigger problem than RAM. Constantly deleting files to make room for new ones can quickly become frustrating. In that case, the 256GB storage option on the Narzo 100x is far more practical.

On the other hand, if you’re someone who frequently jumps between multiple apps, edits photos while listening to music, or keeps dozens of browser tabs open, the additional RAM on the Realme Narzo 90x helps the phone keep more apps active in the background.

Neither option is universally better. It simply depends on whether you need more storage or better multitasking.

Battery And Charging: Here’s Where The Real Difference Begins

Battery life is one of the biggest reasons someone would choose the Realme Narzo 100x.

It comes with an 8000mAh battery, which is significantly larger than the 7000mAh battery inside the Narzo 90x.

While a difference of 1000mAh may not sound dramatic on paper, it can make a noticeable difference in real life.

If you’re a college student attending classes all day, someone who travels frequently, or a user who spends hours watching videos, gaming, or using GPS, the larger battery means fewer charging breaks. Instead of worrying about your battery percentage by evening, you’ll likely still have plenty of charge left.

Many users may even find that the phone comfortably lasts into the second day with moderate usage.

However, there’s another side to this Realme Narzo 100x vs Realme Narzo 90x comparison.

A bigger battery naturally takes longer to recharge.

To balance this, Realme has equipped the Narzo 90x with 60W fast charging, while the Narzo 100x supports 45W fast charging.

This creates an interesting trade-off.

If you usually charge your phone overnight, the larger battery on the Narzo 100x makes more sense because charging speed isn’t a major concern.

But if your routine involves plugging in your phone for just 20 or 30 minutes before heading out, the Narzo 90x’s faster charging becomes much more valuable.

Instead of asking which phone is better, ask yourself a different question.

Would you rather charge your phone less often, or would you rather finish charging much faster?

Your answer will probably tell you which model suits your lifestyle better.

Software Experience: The Newer Android Version Matters More Than You Think

Software often gets overlooked during smartphone comparisons, but it plays a big role in how long your phone stays relevant.

The Realme Narzo 100x ships with Android 16, while the Narzo 90x runs Android 15.

You probably won’t notice a huge difference on the first day. Both Realme Narzo 100x vs Realme Narzo 90x feel modern and offer a smooth user experience. The real advantage becomes apparent over time.

Starting with Android 16 means the Narzo 100x is better positioned for future software updates, security improvements, and new Android features. If you plan to keep your phone for three or four years instead of upgrading frequently, starting with the latest operating system is a practical advantage.

For buyers who think long term, this gives the Narzo 100x another point in its favour.

Camera Comparison: Don’t Expect a Major Difference

If you’re hoping one of these phones takes noticeably better photos than the other, you’ll probably be disappointed. Realme has used the same camera setup on both devices, so the photography experience remains almost identical.

Both the Realme Narzo 100x vs Realme Narzo 90x feature a 50MP primary camera paired with a 2MP depth sensor, while the front houses an 8MP selfie camera.

In daylight, you can expect clear and detailed photos with decent colours. Landscapes, portraits, and everyday shots should look good enough for sharing on Instagram or WhatsApp without needing much editing. The primary sensor also captures enough detail for casual photography, making it suitable for family events, travel, or everyday moments.

Portrait mode should produce a pleasing background blur, although edge detection may occasionally struggle with complex subjects like hair or multiple people in the frame. That’s fairly common in this price segment and isn’t unique to either device.

Selfies from the 8MP front camera should be more than sufficient for video calls and social media. Skin tones and facial details are likely to remain consistent across both models since the camera hardware is identical.

Low-light photography is where you’ll notice the limitations. While both phones can capture usable images in dim conditions, don’t expect flagship-level night photography. Photos may show some noise, and finer details could be lost when lighting isn’t ideal.

The bottom line is simple: camera quality shouldn’t influence your decision because both phones are expected to deliver almost the same results.

Price Comparison: Does ₹500 Change the Equation?

Price is often the deciding factor when two smartphones offer similar features.

The Realme Narzo 100x starts at ₹20,999, while the Realme Narzo 90x starts at ₹21,499.

That means there’s only a ₹500 difference between the two.

Although the gap is small, the value each phone offers is quite different.

For a lower starting price, the Narzo 100x gives you:

• An 8000mAh battery
• Android 16 out of the box
• A 256GB storage option
• The same processor and cameras as the Narzo 90x

The Narzo 90x justifies its slightly higher price with:

• Faster 60W charging
• An 8GB RAM variant for heavier multitasking

When the price difference is only ₹500, your buying decision comes down to which features you’ll actually use every day.

If battery life and software longevity matter more, the Narzo 100x offers stronger overall value.

If you regularly multitask and prefer faster charging, the Narzo 90x remains a solid alternative.

Realme Narzo 100x Vs Realme Narzo 90x: Which One Should You Buy?

Now that you’ve seen the complete comparison, choosing between Realme Narzo 100x vs Realme Narzo 90x becomes much easier.

• Keep your phone for several years and prefer the latest Android version.

Which Phone Offers Better Value?

When you compare Realme Narzo 100x vs Realme Narzo 90x side by side, it’s clear that Realme has taken two different approaches.

The Narzo 100x focuses on giving you more runtime, newer software, and greater storage flexibility without increasing the price.

The Narzo 90x, meanwhile, focuses on reducing downtime by charging faster and offering more memory for demanding users.

For most people, the Realme Narzo 100x is likely to be the smarter purchase. The combination of an 8000mAh battery, Android 16, optional 256GB storage, and a lower starting price makes it a well-rounded smartphone that delivers excellent value.

However, if you know that you often run many apps simultaneously and can’t wait long for your phone to recharge, the Narzo 90x is still worth considering.
