realme C75x will be suitable for users who are students, students or ordinary workers, need a product with a fashionable appearance but still ensure high durability and can be used in many different conditions. At the same time, the device also has long battery life and supports fast charging.

However, this product line still has some limitations such as the camera system is not equipped with a wide-angle lens and a telephoto lens. In addition, the screen display quality is only at a basic level, enough to meet the needs of normal use.

Design and display

The overall appearance of the realme C75x is almost unchanged from the realme C75 version launched in late 2024. The product has a square design, with a flat back and beveled edges while the corners are curved for a firm grip.

The back of the device is also finished in a matte finish, which helps to limit fingerprints during use. The overall quality of this product is relatively good and sturdy, with no creaking on the back or frame.

realme C75x is one of the few smartphones in the popular segment equipped with water and dust resistance that meets all three standards IP66, IP68 and IP69. Normally, other manufacturers will choose to cut down on water resistance to save production costs, especially for popular devices.

The above equipment allows the device to pass the 60-hour water immersion test at a depth of 2m. In addition, realme also integrates this product with technology to push water out of the SonicWave speaker.

Specifically, when the phone gets wet due to falling into water, the speaker on the realme C75x can vibrate at a special frequency to remove excess water and help the sound come out clearly, without any feeling of distortion or muffled sound.

In addition, the device is also integrated with ArmorShell protection layer that meets the US military durability standard MIL-STD-810H. However, it should be noted that the above technologies are integrated to increase the experience and durability of the device. Users should not rely too much on or test the device in dangerous conditions to avoid risks.

realme C75x is equipped with a 6.67-inch LCD screen with a hole-punch design containing the selfie camera. This screen has a wide viewing angle, soft colors, and a brightness of 500 nits (maximum 625 nits), which is not too high but enough to observe and use outdoors. In addition, this screen also supports Eye Comfort Display technology to reduce blue light, limiting eye strain when used for a long time.

The most notable feature of this screen is the support for a 120Hz refresh rate, higher than the 60-90Hz of most competitors in the same segment. This feature makes swiping and touching smoother, especially when playing games or surfing the web.

However, the device's screen only has a resolution of HD+ (720 x 1,604 pixels), while some competitors in the same segment have been upgraded to Full HD+ screen resolution. This makes the displayed image not really sharp, especially when watching videos or reading small text.

In addition, the screen bezel at the bottom edge is significantly thicker than the remaining edges. This makes the overall front design of the device unbalanced.

Performance and battery

realme C75x is equipped with MediaTek Helio G81-Ultra processor, 6/8GB RAM (supports 16GB RAM expansion) and 128/256GB internal memory options. Evaluated through Antutu Benchmark performance scoring software, the device achieved more than 270,000 points.

A quick comparison with some competitors in the same segment, OPPO A3 with Snapdragon 6s Gen 1 chip reached about 240,000 points, Honor X7c using Snapdragon 685 chip reached about 320,000 points, while Samsung Galaxy A16 using MediaTek Helio G99 chip reached 390,000 points.

In real-life experience with some popular games like PUBG Mobile or Lien Quan Mobile, the device can achieve 50-60fps with medium graphics settings.

During more than 2 hours of continuous gaming, the device provides a stable user experience, with moderate heat output, mainly concentrated in the area below the camera but does not cause discomfort.

However, it should be noted that this device will not be suitable for multitasking needs, running heavy tasks such as playing high-graphic games or editing videos. Users should only use the device for common tasks such as watching videos, browsing the web or entertaining with some light games.

The device is equipped with a 5,600mAh battery, supporting fast charging at 45W. realme said the device uses new battery materials to help maintain over 80% of its life after 1,000 charging cycles. In addition, the device also supports reverse charging for other devices.

With mixed usage of many tasks such as calling, texting, web browsing, playing games, watching videos and using 4G connection, this model can meet the needs of 1-1.5 days.

Camera and other features

realme C75x is equipped with a main camera with a resolution of 50MP. In bright enough environmental conditions, the image quality taken from this camera system has good details, natural colors, suitable for everyday use.

However, when used in low light conditions, image quality drops significantly, prone to noise and reduced detail. Another limitation is that the device does not support ultra-wide-angle and telephoto lenses. This makes creativity in photography more limited than competitors with more versatile camera clusters.

In return, the realme C75x is equipped with a number of AI features that allow users to quickly edit images or use the camera system more effectively.

For example, the Circle to Search AI feature allows quick search by circling content on the screen, helping to improve work efficiency. The device's selfie camera has a resolution of 5MP, supporting the AI ​​Clear Face feature to gently beautify the face while still retaining natural lines.

In the low-cost segment alone, the realme C75x is one of the few smartphones equipped with AI features. Of course, these features are still not as diverse as products in the higher segment, but they are enough for users to experience.

Despite being a budget device, the Realme C75x still supports NFC connectivity. This is one of the standard features that is required nowadays, but is often removed by smartphone manufacturers to reduce the selling price.

NFC support makes it easier for users to use the device, allowing them to scan their ID cards or identify their bank accounts right on the device. At the same time, this technology also allows the phone to use one-touch payment applications such as Google Pay.

Summary

realme C75x is sold in the Vietnamese market with prices starting from 4.69 million VND. The device competes with a number of rivals in the same segment such as Samsung Galaxy A16, Xiaomi Redmi Note 14, OPPO A3 or Honor X7c.

The device will be suitable for users who are students, students or ordinary workers, need a product with a fashionable appearance but still ensure high durability and can be used in many different conditions. At the same time, the device also has long battery life and supports fast charging.

However, this product line still has some limitations such as the camera system does not support wide-angle and telephoto lenses. In addition, the screen display quality is only at a basic level, enough to meet normal usage needs.
