Realme C21Y Price in Pakistan & Specs
Realme C21Y — Full Specifications, Features & Price in Pakistan
The Realme C21Y was Realme's battery-first budget phone: a 5,000mAh cell, a 6.5-inch screen, and a triple camera at one of the lowest prices in its lineup. It is no longer sold new, so Pakistan's market is used units — where the C21Y still appeals as a cheap, long-lasting second phone. This guide lists its verified specifications and what to check before buying one.

Design and Build Quality
The C21Y measures 164.5 x 76 x 9.1 mm and weighs 200 g — chunky, but that is the price of a 5,000mAh battery. The build is glass front with a plastic back and frame, finished in Cross Black and Cross Blue with a textured crosshatch pattern that hides fingerprints and adds grip. A rear-mounted fingerprint sensor sits on the back panel. It is a practical, no-frills design built to survive daily knocks rather than win beauty contests.
Display Features
The 6.5-inch IPS LCD delivers 720 x 1600 resolution (~269 ppi) with a waterdrop notch and 400 nits of typical brightness. It is a basic HD+ panel: adequate for YouTube, WhatsApp, and browsing, but not sharp by modern standards, and 400 nits means you will squint a little in harsh midday sun. No high refresh rate here — 60Hz only.
Processor and Performance
The Unisoc T610 (12 nm) is an entry-level octa-core chip: two Cortex-A75 cores and six Cortex-A55 cores at 1.8 GHz, with a Mali-G52 GPU. These are manufacturer specifications, not tested performance. Unisoc chips are less common than Snapdragon or MediaTek in Pakistan, which mainly matters for repair shops and custom ROM support — for everyday use it performs like other budget chips of its era: fine for calls, social apps, and video, not for demanding games.
RAM and Storage
The main listed configuration is 4GB RAM + 64GB built-in storage, with a 3GB + 32GB variant also listed in some markets. 4GB/64GB is the minimum sensible buy in 2026 — the 3GB/32GB version will feel cramped fast. A dedicated microSD slot means storage expansion never costs a SIM slot.
Camera Features
The triple rear camera combines a 13MP main sensor (f/2.2, PDAF) with 2MP macro and 2MP depth helpers, plus LED flash, recording 1080p video at 30fps. Daylight photos from the main sensor are serviceable for the price; the macro and depth lenses are basic. The front camera is a modest 5MP (f/2.2) — fine for video calls, not for detailed selfies.
Battery and Charging
The 5,000mAh battery is the C21Y's headline feature — two-day light use was realistic when new, and it remains the main reason to consider this phone. WhatMobile also lists reverse charging, so the phone can top up accessories in a pinch. No fast-charging wattage was confirmed in the spec table, and charging happens over microUSB, so full refills take a while. On a used unit, check real-world drain before buying. No wireless charging.
Software and Updates
The C21Y launched on Android 11 with Realme UI. Realme's update support for this budget model has ended, so a used C21Y runs an old Android version with no further security patches confirmed. Verify that your essential apps — especially banking apps — still support Android 11 before paying.
Connectivity and Additional Features
4G LTE (no 5G), Wi-Fi 802.11 b/g/n, Bluetooth 5.0, GPS with A-GPS/GLONASS/BDS, FM radio, microUSB 2.0 with OTG, and a 3.5mm headphone jack. NFC is not supported. Sensors include accelerometer, compass, proximity, and the rear fingerprint reader.
Variants, Colours and Availability
The verified main variant is 4GB + 64GB in Cross Black and Cross Blue; a 3GB + 32GB configuration appears in some market listings and was not confirmed for Pakistan. The C21Y is discontinued, so only used units are available — and do not confuse it with the Realme C21 (a different model with a different chipset).
Price in Pakistan and PTA Information
No verified current (2026) price exists — the C21Y is discontinued. WhatMobile lists Rs. 24,999 for the 4GB + 64GB configuration, but that is a historical retail figure, not today's used-market value. Confirm the current price with Zohaan Mobile Gallery before buying.
PTA: PTA approval applies per device and IMEI, not per model. Before paying, send the phone's IMEI to 8484 and confirm "Compliant" status. How to check PTA approval.

Final Verdict
The Realme C21Y does one thing well: it keeps going. The 5,000mAh battery with reverse charging remains its entire pitch, and as a cheap used phone for calls, WhatsApp, and video, it still delivers that. Everything else — the Unisoc chip, Android 11, microUSB, basic cameras — is firmly dated. Buy it for the battery at a low price, after checking battery health and app compatibility, and it will serve its purpose.
