Realme C31 Review: Price Insights, Full Features, Performance & Alternatives

Realme C31: Budget-friendly brilliance for Bangladeshi users

Realme C31, launched in global markets on March 20, 2022 is a smartphone that offers a great value for money. This phone was designed with Bangladeshi users' budgets in mind. It features a stylish, Unisoc processor T612, triple camera setup and a large 5000mAh power supply. It will still be a good daily smartphone in 2025 for first-time and student users. Realme C31 is gaining popularity in Bangladesh due to its sturdy build, Realme UI improvements, and the support of popular local applications. This review will explore the Realme C31's price, specs, performance in the real world, and whether you should buy it in the current market.

Unboxing: A Minimalist, Practical Design for Bangladeshi Users

The Realme C31 is a simple, straightforward phone. In the yellow signature box you will find the Realme C31, the micro-USB cable, the 10W charger and SIM ejector, as well as the standard documentation. The phone comes without a silicone case and earphones, as is to be expected for a device at this price.

This phone is surprisingly high-end for its price range. The Dynamic Texture design and the curved body provide a great grip, ideal for everyday commuting in Bangladesh and heavy use. Its 6.5-inch screen is large, vibrant and a great value for its price. The Realme UI is based on Android 11 and looks clean when you boot up the phone.

Realme C31 is a great choice for first-time buyers, students or those looking to upgrade their phone in Bangladesh. It has a solid build quality, dependable software and slick design. The Realme C31 clearly targets to provide essential smartphone features for an ultra-budget.

The design and build quality: lightweight, durable, and stylish for everyday Bangladeshi use

Realme C31 is a budget device that impresses thanks to its thin 8.4mm thickness and featherweight 197g, which makes it comfortable enough for daily use. Realme's Dynamic Texture Design gives it a high-end, premium finish despite being on a budget. The vertical stripe design on the rear resists fingerprints, and gives it a fashionable touch.

The C31 is made of durable polycarbonate and feels solid in the hand. It's built to withstand everyday use in Bangladesh, whether it be in a backpack or on a busy local commute. It is offered in two stylish color choices: Light Silver or Dark Green. This phone will appeal to users of all ages.

This is a great addition for this price. The phone's button placement is ergonomic and it has a three-slot SIM slot for dual SIM and microSD.

Realme has always paid attention to design and functionality, and the Realme C31 is no exception. It's a great option for Bangladeshi consumers who want style, comfort, and affordability on a budget.

The display is large and vivid for the price, but with some limitations

Realme C31 has a 6.5" IPS LCD screen with a resolution of 720 x 1660 pixels. This results in a pixel density of 270 PPI. The screen is not Full HD but the combination of size and resolution works for most basic tasks like video playing, browsing and messaging. This 20:9 aspect and screen-to body ratio of 88.7% makes content immersive on YouTube, Facebook or other apps.

The screen is bright enough to be used indoors, and can also remain visible outdoors in sunlight. Realme boasts a maximum brightness of 400 Nits, which in Bangladeshi conditions is impressive for a device at this price point. The colors are accurate but lean slightly cooler. The viewing angles are good but not outstanding--typical of this price range.

Realme UI optimizers help to ensure a consistent touch response. It's expected that the display will not have a high refresh rate. (60Hz is all it has) This may be noticeable to those who are used to a more fluid screen. The lack of Widevine L1 certifies video to SD on Netflix and other platforms.

The Realme C31 is a good display for Bangladeshi users. This includes students and casual content consumers. It won't please heavy gamers or media enthusiasts, but it does strike the perfect balance of size, brightness and usability for the ultra-budget market segment.

Performance: Efficient and modest for daily tasks, but powerful for power users

Realme C31 runs on the Unisoc T612 Chipset, which is built using a 12nm Process. It has an octacore CPU that features 2x Cortex A75 cores running at 1.8GHz, and 6x Cortex A55 cores operating at 1.8GHz. It offers an entry-level experience for users who are budget-conscious in Bangladesh.

Real-life usage shows that the Realme C31 is able to perform basic tasks like calling, texting, browsing web, scrolling Facebook, and using light apps. Realme UI R Edition is a lightweight version of the Realme UI that removes unnecessary background services and heavy animations.

AnTuTu scores it at around 210.000, which puts it in the same league as rivals such as Redmi 10A and Infinix Smart 7 The Mali-G57 GPU is capable of handling casual games like Subway Surfers and Clash of Clans at low settings. Heavy games such as Asphalt 9 and PUBG Mobile run with frame drop and lag during action scenes.

The thermal management of the device is good. It stays cool even when used for extended periods. Multitasking is possible, particularly with the 4GB variant.

At this price point, the inclusion of UFS storage rather than eMMC allows for faster loading times of apps and smoother handling of data. Power users and mobile gamers, however, may eventually find that the performance is limited.

Realme C31 is a good choice for Bangladeshi students or first-time users of smartphones. It's also a great option for secondary phones. The Realme C31 has optimum performance for Bangladeshi ultra-budget expectations.

The Realme UI R Edition is a lightweight operating system and UI designed for speed.

Realme C31 is powered by Realme UI R Edition, a version optimized and simplified of Realme UI. The OS was designed for lower-end phones and offers smoother performance through the elimination of heavy animations.

It has a clean interface and minimal bloatware. Only a handful of pre-installed applications can be removed if necessary. Even with 3GB of RAM, the navigation is quick and apps launch quickly. Dark Mode, App Cloner and Optimized Notification Control are among the small, but very useful, features that users will enjoy.

Realme does not confirm a major OS update for this device. The security patch update is released quarterly but less frequently than with midrange devices.

Realme UI R Edition is a software solution for Bangladeshi users that prioritizes speed over aesthetics. It lacks the customization options and Android's new features but delivers a solid performance for users on a budget who are looking to get reliable daily use without excessive complexity.

Limitations in low light for the camera: It is only capable of capturing daylight.

Realme C31 has a triple-camera setup at the rear, including a 13MP sensor with f/2.2, a macro 2MP lens and a depth monochrome sensor. This may seem impressive on paper for a smartphone in the sub-Rs15k segment but results can vary.

The 13MP camera can produce decent photos in well-lit conditions outdoors, with natural colors and a good dynamic range. The autofocus works well during daylight hours, and shutter speed is fast. Fine details can be softened, particularly when zooming. Although the macro sensor provides average shots of close-ups, its use is limited by inconsistent focus and poor resolution.

The depth sensor is a great asset to portrait mode, but the edge detection can be a problem. Background blur can look unnatural in difficult lighting situations.

The C31's performance in low-light conditions is its biggest weakness. The images are grainy and noisy, with reduced sharpness. Without proper lighting and a dedicated night mode the results can be poor.

It is ideal for video calling and casual selfies. The front 5MP camera has a f/2.2 aperture. Skin tones are good in bright light, but the details lack. The front-facing sensor takes noisy and washed out photos in low lighting.

The maximum video recording resolution is 1080p@30fps, for front and back cameras. There's no image stabilization. It is possible to use the footage, but it will be shaky when taken by hand.

Realme C31 is a decent option for Bangladeshi users who are looking for an entry-level camera to use in daylight and for social media postings. However, if photography--especially in low light--is a priority, better alternatives exist in the same price range.

All-day Power and Slower Charging

Realme C31 has a large 5000mAh capacity battery. This is one of the strongest features for this device in its price range. The battery easily lasts for a day and half with regular use, such as browsing the web, using social media and light games, or streaming YouTube. It can last up to 2 days for lighter users. This is ideal for Bangladeshi students or rural users who do not have access to charging stations.

Battery drain during standby is minimized thanks to the energy-efficient Unisoc T612 processor and Realme UI R Edition. The battery is reliable even during prolonged mobile data use or gaming.

The 10W charge speed is a major drawback, as it feels outdated in 2025. It takes almost 2.5 hours to charge from zero to 100 percent, which is inconvenient for users that need frequent top-ups.

Realme has not included fast charging on this model. This is a lost opportunity, as some competitors now offer 18W and even 33W charging within the same market segment.

The Realme C31 is a great battery phone for Bangladeshi users. However, its old charging technology may not be ideal for those who need to recharge their phones faster.

Bangladeshi Networks: Connectivity and Networks: Reliable and Practical

Realme C31 offers a good set of connectivity features that are suitable for most Bangladeshi users. The Realme C31 supports dual Nano SIM cards, with 4G VoLTE in both slots. This ensures reliable calls and steady data speeds across all Bangladeshi major networks, such as Grameenphone and Robi. VoWiFi support is available, which can be a great bonus to users who live in an area with poor signal coverage.

The device has Wi-Fi 802.11b/g/n for wireless connectivity. It is not dual-band (5GHz). Bluetooth 5.0 allows for fast, stable, and reliable pairing of accessories such as wireless earbuds and Bluetooth speakers.

With GPS, GLONASS and BDS support, navigation is precise, which makes it ideal for Google Maps or ride-sharing apps, as well as food delivery services, widely used across Bangladesh.

The micro-USB connector is a major drawback, as it feels out-of-date in 2025 with most phones moving to USB Type C. The phone does support USB OTG which allows users to attach flash drives and other USB accessories.

Realme C31 is a reliable device that offers dependable connectivity. It meets the needs of Bangladeshi consumers, but dual-band WiFI and more modern ports would be welcome.

Storage Options: Flexible and Expandable for Bangladeshi Users

Realme C31 comes in two different storage options: 4GB of RAM and 32GB of storage. Both use UFS 2.2 for faster access to data compared with traditional eMMC. The 4GB version offers smoother multitasking and faster app launch.

The C31 comes with a microSD slot that supports expansions up to 1TB for users who need more storage space. Bangladeshi users, who are heavily reliant on media from their country and like to store data off-line, will find this feature particularly useful.

Triple-card slots allow simultaneous usage of dual SIM and microSD cards, eliminating the necessity to decide between storage expansion and dual SIM functionality. The feature will be especially helpful for those who manage both their personal and business contacts.

The Realme C31 offers a good balance between performance and flexibility. It is able to meet the needs of Bangladeshi customers.

sound quality is good for everyday use, but not for audiophiles

Realme C31 has a rear-mounted single speaker. This is common for smartphones in the budget range. The placement of the speaker can cause muffled sound when held or laid flat. The speaker is loud enough for notifications and calls, but it's not clear or deep for video playback.

Users may prefer to use the 3.5mm jack for a richer audio experience. This jack supports both wired and wireless headphones, an important feature for Bangladeshi users, who are accustomed to using traditional audio accessories. Bluetooth 5.0 offers wireless audio connectivity, allowing for a variety of listening styles.

The Realme C31 audio system is adequate for daily tasks, but it may not be sufficient to satisfy those who are looking for high-quality music for entertainment.

Unique Features: Practical Innovations for Budget-Conscious Bangladeshi Users

Realme C31 is a budget-friendly smartphone with a number of features that are designed for everyday use. The TUV Rheinland smartphone High Reliability Certificate ensures its durability and makes it ideal for everyday use in Bangladeshi environments.

Dynamic Texture Design enhances the device's aesthetic appeal and provides a more comfortable grip. This reduces the risk of an accidental drop. The side-mounted finger print sensor provides quick access and security to the device. This feature is usually reserved for high-end devices.

The triple card slot allows users to have multiple SIMs, and also add additional storage. It can accommodate two Nano SIMs, and one microSD at the same time, with a maximum expansion of 1TB. The Bangladeshi user can store extensive media collections or manage personal and business contacts with this flexibility.

The Ultra Saving Mode also extends the battery life, and allows users to remain connected with only a minimal amount of charge. This is incredibly useful in places with little access to electricity.

Realme C31 is a budget smartphone that offers a lot of features, but also focuses on reliability and usability. This makes it an excellent choice for consumers who are looking to save money without having to compromise essential comforts.
