The Realme C21Y arrived in Bangladesh as an upgraded, higher-performance successor to the popular C21, replacing the entry-tier Helio G35 chipset with the significantly faster 12nm Unisoc Tiger T610 processor featuring Cortex-A75 performance cores. Designed with a cross-hatch geometric art micro-texture that resists fingerprint smudges and light water splashes, measuring 164.5 x 76.0 x 9.1 mm and weighing 200 grams, the smartphone is available in Cross Blue and Cross Black. Dominating the front is an expansive 6.5-inch HD+ (720 x 1600 pixels) IPS LCD mini-drop display boasting an 81.59% screen-to-body ratio, 270 ppi pixel density, 420 nits brightness, and scratch protection provided by Corning Gorilla Glass. Under the hood, it is powered by the 12nm Unisoc Tiger T610 octa-core processor (2x1.8 GHz Cortex-A75 & 6x1.8 GHz Cortex-A55) paired with an ARM Mali-G52 GPU, coupled with up to 4GB of LPDDR4X RAM and up to 64GB of eMMC 5.1 internal storage, expandable up to 256GB via a dedicated 3-card microSD slot. Mobile photography is driven by an AI triple rear camera array headlined by a 13MP primary sensor (f/2.2) with PDAF and Super NightScape, accompanied by a 2MP dedicated macro lens (4cm focus) and a 2MP portrait depth sensor, complemented by a 5MP front selfie camera. Powered by a heavy-duty 5000 mAh battery with 10W charging, Super Power Saving Mode, and reverse wired charging capability via microUSB 2.0, an ultra-fast rear-mounted physical fingerprint scanner, a 3.5mm headphone jack, FM Radio, and TÜV Rheinland Smartphone High Reliability Certification, the Realme C21Y delivers an outstanding balance of responsive processing speed, battery longevity, and proven everyday durability.
