The Realme C11 2021's case is made of plastic, its surface is lightly ribbed. Thus, the device lies stably in the palm and hardly collects fingerprint marks. On its rear panel there is a camera unit and flash - a completely traditional solution. On the front, we see a satisfyingly large screen, which has a large teardrop-shaped notch for the front camera.

The Realme C11 2021 feels nice in the hand. It is easy to handle with one hand. Its low weight - only 190 grams - also contributes to the positive impressions. The device is available in two colours - blue and grey.


The smartphone features a 6.52-inch screen with IPS matrix and 90% sRGB color space range. The images are colour saturated, bright and have enough contrast. They are visible from any angle. You'll also love the maximum brightness of 480 nits. This means you can comfortably use the Realme C11 2021 outdoors on a sunny day. You won't feel any discomfort in the dark either, as there is an automatic brightness adjustment.

The screen resolution of the Realme C11 2021 is 1600 x 720 with a density of 269 pixels per inch. It's not a record-breaking figure, but it's standard for cheap smartphones. The touch layer distinguishes up to 10 touches simultaneously. From the settings, you can choose a dark theme, adjust the color temperature, or turn on vision protection mode. Impressively, the screen takes up almost 90% of the front panel.

The manufacturer has also offered an auto power-on feature for the device. Thus, when you take the Realme C11 2021 in your hands, it will turn on. This feature blends well with the facial recognition.


The smartphone is based on a 28nm UniSoC SC9863 chip platform, which is a typical solution for budget models. The processor includes a total of 8 cores, of which four are Cortex-A55 clocked at 1.6 GHz and another four Cortex-A55 clocked at 1.2 GHz. The graphics is a PowerVR GE8322. Under load, you won't feel any heating or slowdown in the processes.

Realme C11 2021 is available in one modification - with 2 GB of LPDDR4X RAM and 32 GB of eMMC 5.1 storage, which you can expand using a microSD card.

From the smartphone you can hang smooth operation and no problems when playing games with low settings. Its communication capabilities are standard, and there is support for NFC module for contactless payments.

The factory operating system has been lightened - Android 11 Go.


One of the serious downsides of the Realme C11 2021 will be found in its photo capabilities. Its rear camera is single, which is rare in 2021. In enough light, however, you can count on decent shots - with acceptable detail and beautiful colors. The more complex the shooting conditions become, the more challenging it will be to produce good videos and photos. You'll encounter noise, blur, and other unpleasant effects. HDR mode is not always up to the task.

The selfie camera in turn is also single, barely 5-megapixel. The manufacturer has stated that it uses artificial intelligence algorithms, but don't expect miracles from them. As for video recording, with the Realme C11 2021 in hand you can count on a maximum of 1080 pixels at 30 frames per second.

The modest features of the rear and front cameras is complemented by a simplified interface that you'll easily get used to. Various modes are available to control the bokeh effect, burst, interval, panorama and manual modes.

Autonomous operation

An important trump up the Realme C11 2021's sleeve is good autonomous operation. This feature is one of the important ones in the budget class. The battery capacity is 5000 mAh and you can count on a day and a half of operation while actively saving charge. If you enter superfrugal mode, i.e. turn the device into a phone call-only device, you will have a whole week available. However, this is unlikely to happen.

At comfortable brightness, you'll need a charger after 22 hours of watching videos or 10 hours of gaming.

Since the Realme C11 2021's battery capacity is large and the smartphone doesn't support fast charging technology, you'll need to spend more time recharging. At least 3 hours. In the first hour, you will recover about 40%, which is a good indicator.

An advantage of the Realme C11 2021 is that it can be used as an external battery. So you will be able to recharge your other devices with it. In Stand By mode, its battery can last for 43 days.

Interesting functions and features

More and more manufacturers are responding to consumers' need for security that they won't be left without a smartphone. In the Realme C11 2021, you get Ultra Saving Mode - it guarantees you a longer run with the device before its battery resets.


This model is good enough for its price. It's an excellent choice for kids and people who don't have big demands on their smartphone. For them, the most important thing is to be able to make full use of various apps, watch videos, videos and surf the web. The battery is actually high capacity, which is good considering the economical charge consumption.
