Motorola Moto G66j 5G

The Motorola Moto G66j 5G has a non-folding, non-rugged form factor with dimensions of 165.8 mm in height, 76.3 mm in width, and a thickness of 8.5 mm, with a total volume of approximately 107.53 cm³ and a weight of 200 g. A standout aspect of its build is the IP68 rating, which certifies the device as fully waterproof and capable of withstanding submersion at depths of up to 1.5 metres.

The Motorola Moto G66j 5G features a 6.7″ IPS LCD touchscreen with a resolution of 1080 x 2400 px and a pixel density of 391 ppi, delivering a reasonably sharp image across its single screen — there is no secondary display. The panel runs at a 120Hz refresh rate and reaches a typical brightness of 1000 nits, while an Always-On Display mode keeps glanceable information visible at all times. It is protected by Gorilla Glass 7i for added scratch and impact resistance. HDR10, HDR10+, and Dolby Vision are not supported.

The Motorola Moto G66j 5G is driven by the Mediatek Dimensity 7060 chipset, built on a 6 nm process with a 5W TDP and an octa-core CPU configured as 2 cores at 2.6 GHz and 6 cores at 2 GHz, supporting 8 threads, 64-bit processing, big.LITTLE technology, and Heterogeneous Multi-Processing. It comes with 8 GB of LPDDR5 RAM running at 3200 MHz across 4 memory channels, delivering a maximum bandwidth of 51.2 GB/s, while internal storage stands at 128 GB with expandability up to 2 TB via external memory. Graphics are handled by the integrated IMG BXM-8-256 GPU, which features 4 execution units, 64 shading units, and a clock speed of 900 MHz, with support for DirectX 12, OpenGL ES 3.2, and OpenCL 2.0. The chipset also integrates LTE, and includes security features such as NX bit and TrustZone, alongside a 2 MB L3 cache and a maximum supported memory ceiling of 16 GB.

The Motorola Moto G66j 5G has a dual-lens rear camera system pairing a 50 MP primary sensor at f/1.8 with an 8 MP secondary lens at f/2.2, both using CMOS technology without a back-illuminated sensor. Autofocus is handled via phase detection and touch AF, with continuous autofocus available during video recording, though laser autofocus is absent. The rear setup includes a single LED flash — not dual-tone or RGB — and there is no optical image stabilization or optical zoom. Manual controls cover exposure, ISO, focus, and white balance, while burst mode, HDR, slow-motion video, timelapse, and in-camera panoramas are all supported; 360-degree panorama, RAW capture, manual shutter speed, HDR10 recording, Dolby Vision recording, and 3D recording are not available. On the front, a 32 MP single-lens camera sits at f/2.2 in a standard position above the display — not under it — and has no dedicated flash.

The Motorola Moto G66j 5G runs Android 15, a free and open-source platform that supports multi-user operation, split-screen multitasking, Picture-in-Picture, widgets, sharing intents, and the ability to play games while they download. Privacy is addressed through location controls, camera and microphone access management, clipboard warnings, and app tracking blocking, though cross-site tracking blocking and Mail Privacy Protection are absent. Personalization options include dark mode, dynamic theming, theme customization, and customizable notifications, while practical tools such as full-page screenshots, a media picker, Live Text, extra dim mode, battery health check, offline voice recognition, voice commands, app offloading, child lock, and device tracking are all present. OS updates do not arrive directly from the vendor, and the device does not support focus modes, Wi-Fi password sharing, or Quick Start.

The Motorola Moto G66j 5G is equipped with a 5200 mAh rechargeable battery that is non-removable and supports 30W wired fast charging. Wireless charging is not available. The device includes a battery level indicator, giving users a clear read on remaining charge at a glance.

The Motorola Moto G66j 5G includes a 3.5 mm headphone jack and stereo speakers for audio output. On the wireless audio side, none of the advanced Bluetooth codec options — aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC — are supported.

The Motorola Moto G66j 5G supports 5G cellular connectivity alongside Wi-Fi 4 and Wi-Fi 5, Bluetooth 5.3, and NFC, with SIM options comprising one physical SIM and one eSIM. Wired connectivity is handled via a USB Type-C port running USB 2.0, and there is no HDMI output. Download speeds reach up to 2770 Mbits/s and upload speeds up to 1250 Mbits/s. The device includes a fingerprint scanner for biometric authentication, while 3D facial recognition and an iris scanner are not present. Location is covered by GPS and Galileo satellite support, and onboard sensors include a gyroscope, accelerometer, and compass — a barometer, infrared sensor, heart rate monitor, and ANT+ support are all absent. An external memory slot is available for storage expansion, and the device does not include a built-in projector, stylus, motion tracking, optical tracking, crash detection, satellite SOS, or DLNA certification.

The Motorola Moto G66j 5G includes a video light to assist with recording in low-light conditions. The display is flat rather than curved, uses no e-paper technology, and is not protected by sapphire glass.
