Realme 12 5G

The Realme 12 5G has a conventional, non-folding form factor standing 165.6mm tall, 76.1mm wide, and 7.7mm thick, with a total volume of around 97cm³ and a weight of 188g. It carries an IP54 rating, meaning it offers a degree of protection against dust and water splashing from any direction, though it does not have a rugged build. A noteworthy aspect of its design credentials is a French Repairability Index score of 8.2 out of 10, indicating that the device is relatively straightforward to repair by standard assessment criteria.

The Realme 12 5G features a 6.72″ IPS LCD touchscreen with a 1080 x 2400 px resolution and a pixel density of 392 ppi, producing a reasonably sharp image across its large panel. It runs at a 120Hz refresh rate, which helps keep on-screen motion smooth during scrolling and general interaction, and reaches a typical brightness of 800 nits. The display does not include branded damage-resistant glass, an Always-On Display mode, a secondary screen, or support for HDR10, HDR10+, or Dolby Vision.

The Realme 12 5G is driven by the MediaTek Dimensity 6100 Plus chipset, manufactured on a 6nm process and configured with eight CPU threads split across two performance cores at 2.2GHz and six efficiency cores at 2GHz, making use of big.LITTLE architecture and Heterogeneous Multi-Processing for workload distribution. Graphics are handled by the integrated Mali G57 MC2 GPU running at 950MHz, which supports DirectX 12, while the SoC also integrates LTE. The device ships with 8GB of LPDDR4 RAM operating at 2133MHz alongside 256GB of internal storage, and the platform supports a maximum memory configuration of 12GB; multithreading and 64-bit processing are both supported. In benchmark testing, the chipset achieves an AnTuTu score of 442,599.

The Realme 12 5G uses a dual-lens rear camera system led by a 108MP primary sensor with an f/1.8 aperture alongside a 2MP secondary lens at f/2.4, both using a CMOS sensor type without back-side illumination. Autofocus options include phase-detection and touch autofocus as well as continuous autofocus during video recording, though laser autofocus is not present, and there is no optical image stabilization or optical zoom. Video capture tops out at 1080p at 30fps, with slow-motion recording supported but no HDR10 or Dolby Vision recording. Manual controls cover exposure, ISO, focus, and white balance, while shooting modes include burst, panorama, timelapse, and HDR, though raw capture and manual shutter speed are not available. A single LED flash is fitted at the rear — not dual-tone or RGB — and there is no front-facing flash. The 8MP front camera sits at f/2.0, operates as a single lens, and is positioned in the standard location rather than under the display.

The Realme 12 5G runs Android 14 and comes with a broad set of privacy and usability features. On the privacy side, it offers clipboard warnings, location privacy options, camera and microphone access controls, and the ability to block app tracking, though Mail Privacy Protection and cross-site tracking blocking are not included. The interface supports theme customization, dynamic theming, dark mode, and an extra dim mode, while productivity is aided by split-screen multitasking, Picture-in-Picture, full-page screenshots, a media picker, customizable notifications, widgets, sharing intents, and the ability to play games while they download. The device also includes on-device machine learning, offline voice recognition, voice commands, Live Text, phone tracking, a child lock, battery health check, and multi-user support. Features absent from the software include Wi-Fi password sharing, focus modes, app offloading, direct OS vendor updates, Quick Start, and the ability to function as a PC.

The Realme 12 5G is equipped with a 5000mAh rechargeable, non-removable battery that supports 45W fast charging, and a compatible charger is included in the box. A battery level indicator is present, making it straightforward to monitor remaining charge at a glance. Wireless charging is not supported.

The Realme 12 5G includes a 3.5mm headphone jack and stereo speakers, covering the basics for both wired listening and on-device audio output. However, it does not support any high-resolution Bluetooth audio codecs — aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC are all absent — and there is no built-in radio.

The Realme 12 5G supports 5G connectivity alongside Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), and accommodates two SIM cards with a maximum download speed of 3300 MBits/s. Bluetooth 5.2 and NFC are both present, and the device connects via USB Type-C, though the USB standard is version 2. An external memory slot is available for expandable storage. On the sensor and navigation side, the phone includes GPS with Galileo support, a compass, gyroscope, and accelerometer, while a fingerprint scanner handles biometric authentication — 3D facial recognition and an iris scanner are not featured. Features absent from this model include HDMI output, an infrared sensor, a barometer, a heart rate monitor, ANT+ support, DLNA certification, crash detection, emergency SOS via satellite, a stylus, motion tracking, optical tracking, and a built-in projector.

The Realme 12 5G includes a video light, which can be used to illuminate subjects during video recording. The display is flat rather than curved, uses neither sapphire glass nor an e-paper panel.
