The Realme C21 is another such phone — one that is designed to deliver the basics, and not pretend to be a phone that it’s not.
Aimed at being the first smartphone for rookies, students and for those who simply want a reliable second phone, the Realme C21 offers good performance, impressive battery life and a rugged design — and remains highly affordable too.
But is it worth buying in 2025’s crowded budget market? Let’s break it down.
DESIGN & BUILD/Rough, Random and Minimal
The Realme C21 is reasonably sturdy, for a budget phone, at least. It has a textured plastic back, which resists fingerprints and helps you keep a grip — effects which can be appreciated from those with a disdain for phone cases.
There is a geometric pattern on the back panel, which adds a little flash, but the square-shaped camera module gives it a modern look.
The phone is roughly 190 grams and has a 6.5-inch HD+ display, and it feels just right in the hand — not too big, not too small.
Realme also says that the phone is also TÜV Rheinland certified for quality, durability, which gives it more weight when it comes to build strength.
Presentation: No-frills, but It Works
The Realme C21 offers a 6.5-inch IPS LCD display that has an HD+ resolution (720 x 1600 pixels). It isn’t going to win any awards for sharpness or colour accuracy, but it’ll do.
The screen is bright for indoor use and also works under sunlight, but is not the best for binge-watching or reading in sunny environments.
That said, it’s more than fine for casual YouTube watching, internet browsing and Twitter scrolling.
Performance: Good for the Basics Only
The C21 is powered by MediaTek Helio G35 SoC ticking alongside 3GB or 4GB RAM and 32GB or 64GB onboard storage. Performance is also ok for daily use such as calling, texting, social media and light app usage.
But it’s not the device for you, if you’re hoping to play heavy games or run taxing apps.
You can multitask, and you’ll find there’s the occasional pause or slow response as you move between apps.
Yet for newcomers or feature phone converts, it gets the job done OK.
The phone does offer a separate microSD card slot, so you can easily expand storage.
Battery Life: The Real MVP
Battery life is where the C21 shines. It comes with a 5000mAh battery, so normal usage can take you a day and much more.
In practice, lighter users will get almost two full days out of it before requiring a charge.
It charges using a micro-USB port, a detail that feels particularly dated in 2025, and the 10W charger it’s packaged with is far from fast. That said, the long battery life more than compensates for the slow rate of recharging.
Camera Setup: Standard, With a Few Surprises
The phone comes with 13MP main camera at the back, and it is paired with two 2MP shooters for macro shots and depth information. The main camera does well for detail and natural colours in daylight.
Performance in lowlight, though, is middling at best with both noise and blur quite visible.
The 5MP front camera does do an okay job at video calls and selfies, but it’s nothing to boast about. Though, at this price, the expectations must be kept realistic.
Software Experience
Realme C21 is based on Android 10 (Go Edition) with Realme UI out of the box. The UI is quite minimal, fairly clean and is easy to use.
However, being an older Android version, it also misses out on some new features and may not be updated for as long.

Realme C21 Final Verdict
The Realme C21 is an archetypal example of what we mean by a budget phone done right — not too flashy, not too powerful, but reliable in the areas where it counts.
It’s sturdy, has a great battery life and does basic things without much fuss.
It’s no power user or gaming phone, but it makes for a great starter phone for those looking to have the basics in a phone that works — and works reliably.
If you need something affordable under ₹9,000 for your Android phone, the Realme C21 makes sense, provided you know what to expect
