The Major Highlights of Realme C21:

Design:

The Realme C21 presents a modern body outlook in Cross Blue and Cross Black colours. Realme has made this mobile’s body with plastic and included a display of glass. The phone looks great; it is comfortable to grip and not feels cheap at hand. Its shape dimensions are- 165.2 mm x 76.4 x 8.9 mm, and its weight is nearly 190 grams.

Display: 

The C21 has got a 6.5-inch IPS LCD display with a resolution of 720 x 1600p. The pixel density of the panel is 270 PPI, and it offers a wide 20:9 aspect ratio. Regarding the price, this HD plus panel perfectly exhibits natural colours and contrast. Display’s viewing angle, outdoor brightness is okay, and you won’t face any kind of negativity problems in your daily usage.

Chipset and Memory:

Realme has established a MediaTek Helio G55 SoC for the C21. The G35 has eight cores with a PowerVR GE8320 GPU. (8 cores, clocked at 2.3 GHz, based on Cortex A53). Ram and Internal Storage: The smartphone features a 3/4 Gb of Ram with 32/64 GB of inner memory option. 

With the combination of fast Ram and enough storage, the MediaTek Helio G35 will let you complete your daily tasks with ease. Also, you can play games like ‘Free Fire’ without issues. Though it’s not a heavy gaming chip, you will get a stable performance from it.

Camera:

The C21 brings three cameras on the rear function. Emphasizing- a 13 MP primary + 2 MP macro + 2 MP B&W lens. And it only has a 5MP single camera for the selfie.

Camera Performance: You will get an average camera performance with its 13 MP rear and 5 MP front-facing camera. The 13 MP back camera is good enough to click your moments. But when you zoom in on the picture, you may find some lack of details. Same for the 5 MP selfie camera. We expect that after getting a system update, its camera performance- will be improved.

Network and Connectivity, Sensors:

To connect you with the world- Realme packed the device with- 4G LTE, 3G, and 2G networks. And the C21 more brings Micro-USB 2.0, FM radio, Bluetooth version 5.0, Wi-Fi 802.11, mobile hotspot support, GPS with A-GPS, Reverse charging support, and a 3.5mm earphone jack.

Sensors: All the mandatory sensors you will get- an accelerometer, a proximity sensor, a light sensor, a Magnetic induction sensor and a gyroscope sensor. To keep your files safe- the device established a back-mounted fingerprint scanner, which is secure, reliable and fast.

Battery Backup and Operating System:

The C21 proffers a heavy-duty 5000 mAh fixed battery with a 10W regular adapter. The brand has asserted that this massive battery will provide up to 2 days of charge backup in formal usage, and 6 hours of continuous gaming. And its 10W normal charger can regain 100% charge within 2 hours approximately. It has no USB C Type support.

OS: Go through the latest Android Ten with Realme UI. It is (Realme UI) almost like a stock version of Android with some additional features. 

Final Opinion:

The ‘C’ series of Realme is a budget series. Now, this phone gets the power from the MediaTek Helio G35 chip. Having a 4GB of ram is not a poor deal at this price. So the hack is if you need a device for basic gaming like ‘Free-Fire’ and every day’s multitasking with long battery life, then you can choose this phone. Otherwise not.
