Realme C100x vs Narzo 100x 5G: Which to Choose

The Realme C100x and Narzo 100x 5G are two budget-friendly smartphones that target different priorities: the C100x focuses on everyday reliability and battery life, while the Narzo 100x 5G emphasizes faster connectivity and a smoother display. If you want 5G support and a higher refresh rate for gaming or streaming, choose the Narzo 100x 5G; if you prefer a simpler, more affordable device for basic tasks, the C100x is the better pick.

Background: Where These Phones Fit

Realme’s C-series has long been its entry-level line, designed for first-time smartphone users or as a secondary device. The Narzo series, on the other hand, was created to appeal to younger users who want gaming features and modern connectivity at a low price. The C100x and Narzo 100x 5G both sit in the sub-$150 range, but they are not direct successors—they serve different buyer profiles within the same brand.

The Narzo 100x 5G was released in 2024 as part of Realme’s push to bring 5G to budget phones. The C100x is an older model, launched around 2021, and it lacks 5G entirely. This age difference explains most of the spec gap between them, from the processor to the display quality.

Key Specifications Compared

• Display: Narzo 100x 5G has a 6.67-inch IPS LCD with a 120Hz refresh rate; C100x has a 6.5-inch IPS LCD with a standard 60Hz refresh.
• Processor: Narzo 100x 5G runs on a MediaTek Dimensity 6100+ chip; C100x uses a MediaTek Helio G35.
• RAM and Storage: Narzo 100x 5G offers 4GB/64GB or 6GB/128GB; C100x comes with 2GB/32GB or 4GB/64GB.
• Camera: Both have dual rear cameras, but the Narzo 100x 5G has a 50MP main sensor, while the C100x has a 13MP main sensor.
• Battery: Narzo 100x 5G packs a 5000mAh battery with 15W charging; C100x has a 5000mAh battery with 10W charging.
• 5G: Narzo 100x 5G supports 5G; C100x is 4G LTE only.

How the Hardware Affects Daily Use

The processor and display are the biggest differences in everyday experience. The Helio G35 in the C100x is a budget chip from 2020, fine for calls, messaging, and light web browsing, but it stutters with heavy apps or multitasking. The Dimensity 6100+ in the Narzo 100x 5G is much more capable—it handles social media, video calls, and even casual gaming without lag.

The 120Hz screen on the Narzo 100x 5G makes scrolling feel smoother and more responsive. This is noticeable when browsing Instagram or reading articles, and it also helps with gaming. The C100x’s 60Hz panel is standard for the price, but it can feel slightly less fluid if you’re used to a higher refresh rate.

Battery life is similar on paper, but the C100x’s less power-hungry chip and lower refresh rate mean it can last longer on a single charge—often a day and a half with moderate use. The Narzo 100x 5G’s faster processor and 120Hz screen drain faster, though it still typically gets through a full day.

Camera Performance: What to Expect

Neither phone is a camera champion, but the Narzo 100x 5G’s 50MP sensor produces noticeably sharper daylight shots than the C100x’s 13MP camera. The extra resolution allows for better cropping and more detail in good light. In low light, both struggle with noise and softness, but the Narzo 100x 5G’s larger sensor helps it capture slightly brighter images.

The C100x’s camera is adequate for basic documentation—scanning documents, taking photos of notes, or casual social media posts. If photography is a priority, the Narzo 100x 5G is the better choice, but neither will replace a dedicated camera.

Software and Updates

Both phones run Realme UI, which is based on Android. The Narzo 100x 5G launched with Android 14 and is likely to receive at least one major update, while the C100x launched with Android 11 and has already received its final update (Android 12). This means the C100x will not get future Android versions or security patches, which is a significant consideration for long-term use.

If you plan to keep your phone for more than two years, the Narzo 100x 5G is the safer bet because it will receive security updates for longer. The C100x’s software is frozen, so it may become vulnerable to security issues over time.

How to Choose: A Simple Decision Guide

• Choose the Narzo 100x 5G if: you want 5G connectivity, a smoother display, better performance for gaming or multitasking, and a more capable camera. It’s also the better choice if you plan to keep the phone for several years.
• Choose the C100x if: your budget is very tight, you only need basic functions like calls, messaging, and light web browsing, and you don’t mind the older software. Its longer battery life on a single charge can be a plus.

If you’re buying new, the price difference between the two is often small (around $20–$30), so the Narzo 100x 5G usually offers better value. However, if you find a heavily discounted C100x, it can still serve as a reliable backup phone or a first phone for a child.

Common Problems and Misconceptions

A common misconception is that the C100x is a “5G version” of the Narzo 100x, but that’s wrong—they are separate models with different chips and features. Another issue is that some users expect the C100x to receive Android 13 or 14 updates, but it won’t, so don’t buy it expecting future software support.

Battery drain on the Narzo 100x 5G can be higher than expected if you leave the refresh rate at 120Hz all the time; switching to 60Hz in settings can extend battery life significantly. On the C100x, users sometimes complain about slow charging (10W), which takes about 3 hours for a full charge—plan accordingly.

Alternatives to Consider

If you’re open to other brands, the Samsung Galaxy A05s, Xiaomi Redmi 12, and Motorola Moto G14 offer similar specs in the same price range. The Galaxy A05s has a 90Hz display and a 50MP camera, while the Redmi 12 offers a larger 6.79-inch screen and a 5000mAh battery. The Moto G14 is a good option if you prefer near-stock Android software.

Within Realme itself, the Narzo 60x 5G is a slightly upgraded version of the Narzo 100x 5G with a 108MP camera, but it costs a bit more. If 5G isn’t essential, the Realme C55 is a solid alternative with a 64MP camera and a 90Hz display.

Frequently Asked Questions

Is the Narzo 100x 5G worth the extra money over the C100x?

Yes, in most cases. The Narzo 100x 5G offers a faster processor, a 120Hz screen, better camera, and 5G support for a modest price increase. The only reason to choose the C100x is if you’re on an extremely tight budget and don’t need any of those features.

Which phone has a better battery life?

The C100x generally lasts longer on a single charge because its weaker processor and 60Hz screen consume less power. However, the Narzo 100x 5G’s battery is still good for a full day of typical use, and it charges faster (15W vs 10W).

Will the C100x get Android 14?

No. The C100x launched with Android 11 and received Android 12, which is its final update. It will not receive Android 13 or 14.

Can the Narzo 100x 5G handle gaming?

Yes, it can handle casual and mid-level games like PUBG Mobile at smooth settings and Call of Duty Mobile at medium graphics. Heavy games like Genshin Impact will run but with lower frame rates and reduced graphics quality.

Does the C100x support 5G?

No, the C100x is a 4G LTE phone. If you need 5G, you must choose the Narzo 100x 5G or another 5G-capable device.

Which phone has a better camera for low light?

The Narzo 100x 5G is better in low light due to its larger 50MP sensor, but both phones produce noisy, soft images in dim conditions. For low-light photography, consider a phone with a dedicated night mode, like the Redmi 12.
