Oppo K12x 5G: Things are getting interesting in the mid-range smartphone category in India, and Oppo’s newest K-series offering — the Oppo K12x 5G — is here to spice things up.
Starting at an attractive price and packing features that skew above its paygrade, this phone is aimed at young users seeking punchy performance, good looks and 5G future-proofing without costing the earth.
Rocket scienceThe Oppo K-series has always had a tricky balancing act between value and high-end performance, and the K12x 5G offers up a similar-clear blend of design flair, long battery life, smooth performance and a spartan, junk-free experience.
So let’s take a deep dive into what this phone offers, and whether it’s worth your hard-earned cash.
Design: It’s Basic, It’s Smooth, But It’s Nice And Comfortable
The Oppo K12x is overall very modern and sleek looking at first glance. It doesn’t overdo anything with flashy bits of design but it feels premium for its pricetag.
Its flat edges, matte finish back panel and slim design provide clean, modern styling. The camera module is big in size, yet looks stylish and sits snugly within a dual-ring arrangement.
It comes in fun color options that will attract a younger audience too and, because it weighs under 190g, doesn’t feel burdensome during long periods of one-handed use.
It has a side-mounted fingerprint sensor, which is a fuss-free scanning method, and generally feels well built.
Screen: Large, Crisp and Smooth
The K12x comes with a Full HD+ AMOLED display measuring 6.67-inches and equipped with a 120Hz refresh rate — a rarity in this price range.
The display is crisp, colours are vibrant and even the brightness is good enough to use outdoors.
Whether you’re binging, gaming or just scrolling through social media, do it all in high definition on the FHD model’s 1080p display.
Oppo’s also put some eye comfort features in and given it always-on-display functionality to help win you over.
Performance: Does the Trick — Smoothly
Under the hood, it is powered by the Qualcomm Snapdragon 695 5G processor and paired with up to 12GB of RAM and 256GB of UFS 2.2 storage.
This combination ensures smooth operation for day-to-day work, including app switch, multitasking, and moderate gaming.
The Snapdragon 695 isn’t the most powerful chipset you can get, but it works well here, and the phone has been fluid and lag-free during our testing.
Gaming is decent for games like BGMI and Call of Duty Mobile at medium settings and heat is well-managed.
The phone is powered by ColorOS 14 running on Android 14 It features a clean UI with less bloatware, more privacy controls and snappier animations.
Camera: A Useful Shooter, Not a Game-Changer
In terms of photography, the Oppo K12x features a 50MP primary sensor and a 2MP depth sensor.
The rear cameras do a good job in daylight — colors are bright, and dynamic range is good for the class. The low-light image quality is fine, and the Night mode helps bring out some usable shots.
For selfies and video calls, the 16MP front camera does a perfectly decent job, though skin tones can occasionally look over-processed.
Video recording is limited to 1080p, and though it’s nothing to write home about, it is more than acceptable for casual social media content.
Battery Life & Charging: Designed For Power Users
The Oppo K12x is a mean powerhouse that will outlast even the most demanding of media consumption binge thanks to an impressive 5500mAh battery.
Even after constantly streaming video, gaming and using the camera the phone comfortably lasts for a day and more.
But the clincher is the 80W SUPERVOOC fast charging, which gives you 0-100% in less than 45 minutes. That’s flagship-class charging speed in a budget phone.
