Infinix Smart 9 HD

The Infinix Smart 9 HD has a standard, non-folding form factor measuring 165.7 mm tall, 77.1 mm wide, and 8.4 mm thick, with a total volume of approximately 107.31 cm³ and a weight of 188 g. It carries an IP54 ingress protection rating, meaning it offers a degree of water resistance against splashing from any direction, though it is not built to a rugged standard.

The Infinix Smart 9 HD features a 6.7″ IPS LCD touchscreen with a resolution of 720 x 1600 px and a pixel density of 262 ppi, paired with a 90Hz refresh rate for smoother on-screen motion. The display does not include branded damage-resistant glass, and it lacks support for HDR10, HDR10+, Dolby Vision, and Always-On Display functionality, nor does it have a secondary screen.

The Infinix Smart 9 HD is powered by the Mediatek Helio G95 chipset, built on a 12 nm process with an octa-core CPU running at 2 x 2.05 GHz and 6 x 2 GHz using big.LITTLE architecture with HMP support, and a Mali G76 MP4 GPU clocked at 900 MHz with 4 execution units and 64 shading units. The device comes with 4GB of DDR4 RAM at 2133 MHz across 2 memory channels with a maximum bandwidth of 10 GB/s, paired with 64GB of eMMC 5.1 internal storage, a 5W TDP, and a maximum supported memory amount of 10GB, though ECC memory is not supported. On the graphics side, it supports DirectX 12, OpenGL ES 3.2, and OpenCL 2, and benchmark results place it at an AnTuTu score of 141,654, a Geekbench 6 multi-core score of 1,738 with a single-core score of 636, and Geekbench 5 results of 1,592 multi-core and 511 single-core, with integrated LTE, TrustZone security, and full 64-bit support rounding out the platform.

The Infinix Smart 9 HD features a single-lens 13 MP rear camera with an f/1.9 aperture and a CMOS sensor, capable of recording video at 1080p and 30 fps, with support for slow-motion recording, though optical image stabilization and optical zoom are not available. Autofocus options include phase-detection autofocus for photos, continuous autofocus during video, and touch autofocus, while laser autofocus is absent. Manual controls cover exposure, ISO, focus, and white balance, and the camera also supports HDR mode, burst shooting, panoramas, and timelapse, though RAW capture and manual shutter speed are not included. Flash is handled by two LED units, though the setup is neither dual-tone nor RGB. On the front, there is an 8 MP camera with an f/2.0 aperture — a single-lens setup without a front-facing flash, an under-display placement, or support for HDR10 or Dolby Vision recording.

The Infinix Smart 9 HD runs Android 14 and includes a broad set of privacy and usability features, such as location privacy options, camera and microphone access controls, clipboard warnings, and the ability to block app tracking, though cross-site tracking blocking, Mail Privacy Protection, and Wi-Fi password sharing are not available. Customization options include dynamic theming, theme customization, dark mode, an extra dim mode, widgets, and customizable notifications, while focus modes and app offloading are not supported. On the productivity side, the OS supports split-screen multitasking, Picture-in-Picture, full-page screenshots, sharing intents, a media picker, Live Text, and the ability to play games while they download, though it cannot be used as a PC and does not offer Quick Start. Additional capabilities include on-device machine learning, offline voice recognition, voice commands, multi-user support, a child lock, battery health check, and device position tracking, though direct OS updates from the vendor are not provided.

The Infinix Smart 9 HD is equipped with a 5000 mAh rechargeable battery that supports 10W fast charging, and includes a battery level indicator for monitoring charge status. The battery is non-removable, and wireless charging is not supported.

The Infinix Smart 9 HD includes a 3.5 mm headphone jack and stereo speakers, along with a built-in radio. On the wireless audio side, the device does not support aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC codecs.

The Infinix Smart 9 HD supports dual-SIM operation with a cellular module, Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), and a USB Type-C port running USB 2.0, with download speeds of up to 600 Mbit/s and upload speeds of up to 150 Mbit/s, though 5G is not available. For navigation, it includes GPS with Galileo support alongside a compass, while NFC, HDMI output, and DLNA certification are absent. Security and biometrics are handled by a fingerprint scanner, with no iris scanner, 3D facial recognition, or stylus included. Onboard sensors cover an accelerometer and an infrared sensor, but the device lacks a gyroscope, barometer, heart rate monitor, and motion or optical tracking, and features such as crash detection, emergency SOS via satellite, ANT+, and a built-in projector are also not present. External memory expansion is supported via a dedicated slot.

The Infinix Smart 9 HD includes a video light, while the display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
