Best Realme C12 and Realme C15 Full Review

Realme C12 and Realme C15  : Can massive batteries make up for a lack of raw power?

Realme’s budget lineup is beginning to get overcrowded, but the business continues to release new versions with minor changes, even if prices stinks.  

Last month, Realme declared the C12 and C15, priced between Rs. 9,000 and Rs. 11,000.  The big characteristic, very literally, is the 6,000mAh battery that both models share.

Considering both smartphones are very similar, except for a couple of differences, I thought it would make sense to review them together.  Most of what I will be referring to applies to both versions.  So, are Realme’s recent budget phones worth purchasing?  Let’s find out.

The Realme C12 and C15 have the exact same design and dimensions.  Both weigh 209g and are rather chunky phones.

The frames and backs are constructed of plastic, but equally phones feel sturdy and nicely put-together.  Both possess a tray on the left for 2 Nano-SIMs along with a microSD card.  In the bottom, we have a headset jack, Micro-USB interface speaker.

There is a’trapezium gradient’ layout on the backs of both models.  This looks nice and does not bring in a great deal of fingerprints.

The Realme C12 and C15 are believed to have fire-resistant back covers and are also splash resistant.

The Realme C12 and Realme C15 both have capacitive rear fingerprint sensors, which worked well in my experience.

Face recognition also functioned just as quickly.  There is a squariish camera module on both phones that sits flush with the body.

 You obtain a water-drop notch for your selfie camera, and in typical budget telephone fashion, there are fairly thick bezels, especially the chin in the base.

The colours on both phones’ displays looked decent for me, however, the quality of the panels is fairly average.  Whites have a tendency to look somewhat murky and viewing angles aren’t so broad.

Neither of these phones includes a case in the box.  One difference between both is that the Realme C12 comes with a 10W charger although the Realme C15 comes with an 18W charger in the box.

Realme C12 and Realme C15 performance: A bit of a battle

Realme has used the MediaTek Helio G35 SoC, that’s the same entry-level chip that we saw from the Realme C11.

It is not the most effective processor in this price segment, especially considering that competing phones like the Narzo 10A and Redmi 9 Prime (Review) have stronger options.

Realme delivered me the 4GB version of this C15, which conducted Realme UI quite well.

The animations were somewhat choppy, and opening certain program menus and loading programs did take a little longer than usual, but casual use was not too bad.

The Realme C12 on the other hand felt markedly slower.  Little things like awaiting the computer keyboard to pop up before I could start typing a message, and maybe simply loading an app, felt a beat slower than on the C15.

Games ran decently, as long as I stuck into simple titles or lowered the graphics quality.  On the Realme C15, I discovered that names such as Need for Speed: No Limits ran fine but in low quality settings.  Videos looked decent but these phones do not offer you the very best viewing experience due to the narrow viewing angles and normal quality of the panels used.

Both phones support Wi-Fi n, Bluetooth 5, and also the simple satellite navigation systems.  You receive Realme UI according to Android 10 on the Realme C12 and C15, featuring the very same shortcuts and gestures that we have seen on most of the organization’s recent offerings.

You will find a lot of preloaded programs too, but most of them are able to be uninstalled.

Realme C12 and Realme C15 battery life: As good as it gets

The major selling point of both phones is their big batteries.  The Realme C12 and C15 both comprise 6,000mAh batteries, which easily delivered a day and half to two full days on a single charge.

These phones smashed all previous records set by Realme telephones in our battery loop evaluation, running for about 32 hours.

If it comes to charging the batteries, the Realme C15 has an advantage thanks to its service for 18W speedy charging.  It still takes about 2 hours to fully control it, however, you can get up to a 45 percent fee in an hour.

The Realme C12 requires a great deal longer to control as it doesn’t support rapid charging, even if you use a high wattage charger.

Realme C12 and Realme C15 cameras: Mediocre at best

The Realme C12 has three back cameras, whereas the Realme C15 includes four.  Both have the same 13-megapixel primary camera, but the others are slightly different.

Another difference is that the C12 has a 5-megapixel front camera whereas the C15 comes with an 8-megapixel one.

The retro camera on the Realme C15 can be used when you pick the’07’ filter in Portrait shooting mode, whereas the monochrome camera is used if you select the’06’ filter.

The Realme C12 does not have the option for blockers in Portrait mode, so it is uncertain whether its monochrome camera is used at all, other than to compute depth.

 During the day, photographs were normally underexposed, with feeble dynamic selection and poor details.  The C15’s wide-angle camera sounds like a wonderful touch, but picture quality is once again quite bad.  Close-ups often fare a bit better with both phones, but you need to have steady hands as autofocus is not the quickest.

Portrait manner worked tirelessly on both phones.  The Realme C15’s retro camera adds an old-style filter to your photos, while the monochrome camera captures vintage-looking black-and-white photos.

I wasn’t expecting much from low profile photos, and sure enough, the Realme C12 and C15 perform very badly when shooting at night.

Shots had feeble particulars, and Night mode did not seem to make any huge difference on each phone.  The autofocus was much slower in low light.

The Realme C12 and C15 could record video up to 1080p, but without any stabilisation.  Footage was usable when shooting at the daylight, but below average during the night.

The Realme C15 does a slightly better job using selfies, thanks to its higher-resolution front sensor.  Even the Realme C12 still manages to hold its own when shooting inside, but it’s not great.


The Realme C12 and Realme C15’s primary redeeming attribute is strong battery life, however they both fall short in pretty much every other location.  We’d have been a bit happier had they’re priced lower, such as the Realme C11.

However at almost Rs. 9,000 for your C12 and Rs. 11,000 for the C15, we think you’d be better off with phones that strive to become better all-rounders.

You do not even have to look too much: Realme’s own Narzo 10A feels just like a better choice than the C12 overall, since it has a more potent SoC and is priced beginning at Rs. 8,999.

There’s also the Narzo 20 and Narzo 20A, which we’re testing right now and could be good choices to the C12 and C15.

For everyone else, any of the choices mentioned previously will offer a much better mixture of battery life and performance.
