2-minute Review [Positives]
  • Looks sleek and eye-catching with its iridescent finish - the plastic back has this rainbow-like effect
  • The front looks trendy with minimal screen bezels and an unobtrusive hole-punch in the top-left corner
  • Samsung has gotten the software part on point with its recent launches, with it's new One UI, that's now one of the better, more streamlined Android skins around - it's especially well suited for big displays like this, packs an intuitive gesture navigation system, and other useful things like a convenient 'dark mode'
  • Good quadruple-camera array - a primary 48MP lens, supported by an 8MP ultra-wide angle unit, 2MP macro camera and a 2MP depth sensor
  • The Galaxy A21s manages to take a pretty good picture from the primary camera - it produces wonderfully detail-rich images with plenty of vibrancy
  • Live Focus mode (portrait mode) allows adjusting the level of blur either before, or after, you press the shutter button, and the results are good
  • Macro mode is also a lot of fun - it captures some crisp closeups
  • Excellent battery life with the 5000 mAh cell - combined with a low-res screen and a power-efficient CPU, it would easily last you for 2 days of moderate use
  • Supports 15W fast charging
  • Pleasant, refreshing design - back is textured similar to other budget realme phones, there is a square-shape camera module similar to the realme C11
  • Front has a similar affair with a dew-drop notch and thin bezels
  • The patterned back almost completely eliminates the chances of getting fingerprints or smudges - it also adds a lot of grip and gives the phone a very solid, sturdy feel
  • Face recognition and fingerprint sensor are quick to unlock the smartphone
  • Large, 6.5 inch IPS display with HD+ resolution - the colors are vibrant with a decent amount of sharpness
  • Sunlight legibility is also good - the display gets bright enough for comfortable outdoor use
  • The Realme C15 comes with Realme UI based on Android 10 which is much more streamlined and clean compared to previous realme phones - it still packs a lot of useful features like Dark mode, Focus mode, Game Space and Personal Information Protection
  • Good quad camera setup for the price - a 13MP primary shooter, an 8MP ultra-wide, a 2MP depth sensor and a 2MP Macro camera
  • The main camera can click photos with good details in bright light - photos have a lot of details, colours have a punch, they come out well even when shot against a direct light source, thanks to the HDR and chroma boost
  • The ultra-wide camera captures a wider perspective (though the details are on the weaker side)
  • The macro camera produces fun, usable photos as long as you give it a lot of light and the correct focal distance
  • The portrait shots look good, and the edge detection is decent as well
  • The 8MP front camera can shoot decent selfies - the portrait mode works for the front camera as well, bringing out a more aggressive bokeh effect than the one produced by the dedicated sensor at the back
  • Decent video recording quality, with a option to shoot slow motion videos
  • Monster 6000mAh battery delivers an incredible 2-3 days of usage easily, making for one of the largest battery life smartphones currently available
  • Supports 18W Fast charging with an included fast charger
  • Realme C15 is worth buying as long as your usage is basic - it has a good display that produces bright colours, cameras manage to deliver beautiful shots and the battery the can last days
2-minute Review [Negatives]
  • Average 6.5-inch TFT LCD - the HD resolution is rather low for a phone at this price, and the colour reproduction isn't great
  • The Galaxy A21s is powered by Samsung's new Exynos 850 chipset, which gets things done and that's about it - it doesn't compete with the powerful processor other phones offer and heavy games are a no go
  • Overall, the Galaxy A21s has quite capable cameras, though they aren't the class-leading
  • On the whole, while the Galaxy A21s is a fashionable choice for the price bracket, and does exceptionally well with battery life and a decent set of cameras - however, it falls a bit behind in terms of performance and display - you will find better all-round options from the likes of Xiaomi, Realme and Motorola
  • Quite hefty, at 209g weight and 9.8 thickness
  • There is no Widevine L1 certification which means that you cannot enjoy HD content on Netflix and Amazon Prime
  • There's still some bloatware that comes pre-installed
  • Performance of the realme C15 is strictly average - the apps begin to lag when you try browsing the internet and running apps in the background simultaneously - as far as gaming is concerned, it is capable of handling light games only such as Temple Run, Candy Crush etc
  • Low light photos are average, as expected, they lack detail and aren't very sharp
  • Uses the old MicroUSB plug, while the competition has started offering USB Type-C in the budget segment
  • If you're looking for a good performing phone with all other bells and whistles, there's the realme Narzo 10 as alternative at similar price
