CMF Phone 2 Pro vs OPPO K13 vs Realme Narzo 80 Pro: Which is the Best Smartphone Under Rs 20,000 in India?

The CMF Phone 2 Pro recently made its debut in India with considerable upgrades over the CMF Phone 1. However, India's sub-20K segment is saturated with competition, although its two primary challengers remain the Realme Narzo 80 Pro 5G and OPPO K13 5G. So without any further delays, let's find out which of these phones you should consider in India's sub-20K segment.

CMF Phone 2 Pro vs OPPO K13 vs Realme Narzo 80 Pro: Comparison

Design

Unlike traditional smartphones in this price range, the CMF Phone 2 Pro incorporates bold design elements, including a minimalist finish and a modular back panel. On the other hand, the Realme Narzo 80 Pro 5G and OPPO K13 feature standard rear panels, although the K13 5G and CMF Phone 2 Pro's edges are less round compared to the Narzo 80 Pro.

Moreover, all three phones feature plastic backs, glass protection on the front, and plastic frames. The OPPO K13 5G and Realme Narzo 80 Pro also feature an IP65 rating for resistance against dust and water, while the Realme Narzo 80 Pro offers flagship-grade resistance to dust and water with its IP68+IP69 ratings. Overall, there's only one standout phone here in terms of overall design and that's the Phone 2 Pro.

Display

All three smartphones feature 120Hz OLED displays, although the screen on the CMF Phone 2 Pro and iQOO Z10 feature higher peak and HBM levels of brightness. Moreover, the CMF Phone 2 Pro's panel also supports HDR10+, while the Realme Narzo 80 Pro 5G supports HDR formats.

Performance

In terms of performance, both the OPPO K13 5G and CMF Phone 2 Pro are evenly matched on paper. Both phones also feature several tweaks to ensure you experience the best gaming experience in the price tag. However, the Realme Narzo 80 Pro and its MediaTek Dimensity 7400 SoC does give it a leg up over the competition. But given the two chips use the same CPU cluster, GPU, NPU, and ISP, don't expect any major differences.

Battery and Charging

In terms of battery capacity, the OPPO K13 emerges as the clear winner, courtesy of its 7,000 mAh cell. Moreover, the Realme Narzo 80 Pro 5G also packs a massive battery, although the CMF Phone 2 Pro's 5,000 mAh cell is still sizeable and easily passed our all-day battery test.

It is worth noting that both Realme and OPPO use silicon carbon battery technology for better long-term viability. Additionally, the Narzo 80 Pro and K13 5G also support faster charging than the CMF Phone 2 Pro.

Software

All three smartphones run on Android 15 with their custom skins on top. However, the similarities between Realme UI and ColorOS are few and far between. Both operating systems offer decent levels of customization but also come with their fair share of bloatware.

On the other hand, NothingOS on the CMF Phone 2 Pro offers a clean and minimalist experience, while offering a plethora of useful features. Additionally, the CMF Phone 2 Pro also offers significantly better software support than the competition.

Cameras

Both the Realme Narzo 80 Pro and OPPO K13 feature similar dual-camera setups, with a 50MP primary sensor and a 2MP depth sensor. Moreover, the two phones also come with 16MP front cameras. However, this is where the CMF Phone 2 Pro blows the competition out of the water.

Nothing has equipped its latest CMF smartphone with a 50MP primary sensor, a 50MP telephoto shooter, and an 8MP ultrawide lens. Moreover, the main sensor on the Phone 2 Pro is larger than those on the K13 5G and Narzo 80 Pro. The Nothing CMF Phone 2 Pro also opts for a 16MP selfie camera.

While all three phones support 4K video recording at 30fps on the rear cameras, the Realme Narzo 80 Pro 5G also brings OIS support on its main lens. However, in terms of optics, the CMF Phone 2 Pro blows the competition out of the water, offering some of the best optics in the sub-20K segment.

CMF Phone 2 Pro vs OPPO K13 vs Realme Narzo 80 Pro: Conclusion

In India's fiercely competitive sub ₹20,000 segment, each handset brings distinct advantages. The Realme Narzo 80 Pro 5G impresses with its flagship grade IP68/69 water dust resistance and slightly faster charging, making it a reliable all rounder. The OPPO K13 5G stands out for its enormous 7,000 mAh battery, delivering unrivalled endurance for heavy users.

However, the Nothing CMF Phone 2 Pro ultimately claims victory: its bold, modular design breaks the monotony of this price band, its triple camera array (50 MP primary, 50 MP telephoto, 8 MP ultrawide) eclipses the dual camera setups of its rivals, and its clean NothingOS atop Android 15 offers smoother, less bloated software with longer update promises.

While the Narzo 80 Pro's marginal performance edge and the K13's battery might sway specific users, the CMF Phone 2 Pro's combination of standout styling, versatile optics, and superior software support makes it the best pick in this segment.
