The iQOO 12 5G recently entered the market in November 2023, featuring the Snapdragon 8 Gen 3 processor.

Additionally, this new handset has a triple rear camera system with a 50MP main sensor, a 50MP ultra-wide sensor, and a 64MP periscope telephoto sensor, along with a 16MP front-facing camera.

Design and build

Starting with the positive aspect, the iQOO 12 5G has a sleek and modern design, especially the glossy porcelain enamel glass back that catches the light and turns heads. It is available in either a bold tri-colour BMW M Motorsport stripe or a minimalist Alpha colourway. However, this attractive design has also brought about some problems that people are facing in real life. These problems are as follows:

  • The glossy finish can make the phone difficult to grip, increasing the risk of drops and accidents.
  • Such a design is more prone to scratches and scuffs, especially without a case.
  • Because of the glossy finish, the phone readily attracts fingerprints and smudges, requiring frequent cleaning.
  • Some users have expressed the opinion that the phone’s durability is compromised due to this design.


There is no doubt that the iQOO 12 5G is a true beast, packed with raw power to handle the most demanding tasks. It is equipped with the Snapdragon 8 Gen 3 processor, which is currently the king of mobile CPUs. It provides ultra-responsive visuals, supports 120W charging, and offers 5G connectivity. However, despite having such power, there are a few downsides that users have observed, as listed below:

  • Although the phone has a 6K VC Four-Zone Cooling system to manage heat, some users have experienced thermal throttling during intense gaming sessions.
  • While the phone has a 5000mAh battery, some users have reported fluctuations in battery life, with some experiencing faster drain than expected.
  • Even though the iQOO 5G has decent software support, a few occasional stutters, glitches, and bugs have been reported on this new release.

Battery life

The iQOO 12 5G has a reputed 5000mAh battery life that promises long-lasting endurance for even the most hungry users. And talking about charging response, the phone supports 120W, which can charge your phone from 0% to 100% in just 15 minutes. Additionally, it has some focused charging modes that suit every user’s needs. However, some users have faced difficulties that are listed below:

  • Users are of the view that frequent use of 120W charging can potentially shorten the battery’s lifespan over time.
  • Some users claimed that the phone experienced higher-than-expected battery drain when it was not in active use.
  • While playing games or charging, the phone can get warm, potentially impacting battery performance.

Camera Quality

The iQOO 12 5G has a versatile camera setup equipped with a triple camera system that comprises 50 MP (main sensor), 50 MP (ultrawide sensor), and 64 MP (periscope telephoto sensor). Not only that, the phone has multiple features such as gimbal stabilisation, AI scene recognition, night mode, portrait mode, and so on. Meanwhile, that camera setup caters to both casual and enthusiast photographers. But here are some difficulties that people find with the camera:

  • Some people complain that photos appear overly processed, with artificial sharpening and smoothing.
  • The colours in photos and videos can sometimes appear oversaturated or inaccurate.
  • Autofocus issues have been reported in certain scenarios, like low-light conditions.
  • Although video quality is decent, some users wish for higher frame rate options for smoother slow-motion footage.

Software and the User Interface

As you are well aware from the phone specs, the iQOO 12 5G runs on iQOO UI 13, which is based on Android 13. It is built with a focus on providing accessibility through clean design, rich customisation options, gaming-centric features, and pre-installed apps that can be uninstalled. However, people have found a few issues with the software and UI mentioned below:
