Infinix Note 40 Pro 4G specifications and in-depth review

Infinix Note 40 Pro 4G

Manufacturer: Infinix

The Infinix Note 40 Pro 4G is a 6.78-inch Android 14 smartphone built around an OLED panel with a 1080 x 2436 pixel resolution, 393 ppi pixel density, and a 120Hz refresh rate. The display reaches a typical brightness of 1300 nits and is protected by Gorilla Glass 5, with a curved profile adding to its overall form. At 190 g and 7.8 mm thick, the phone carries an IP54 rating for water and dust resistance.

Under the hood sits the Mediatek Helio G99 chipset built on a 6nm process, paired with 12GB of DDR4 RAM and 256GB of eMMC 5.2 storage. The rear camera system leads with a 108MP main sensor with optical image stabilization, complemented by two additional lenses, a four-LED dual-tone flash, and manual controls covering ISO, exposure, focus, and white balance. Video recording reaches 1440p at 30fps with slow-motion and timelapse support. Battery capacity stands at 5000 mAh with 70W wired fast charging, 20W wireless charging, and 5W reverse wireless charging, all with a charger included. Connectivity covers Wi-Fi 5, Bluetooth with LDAC, NFC, GPS with Galileo, a gyroscope, compass, infrared sensor, and 3D facial recognition, though 5G is not supported.

Who is this for?

The Infinix Note 40 Pro 4G is well suited to users who want a versatile everyday smartphone with strong charging flexibility, as the combination of 70W wired fast charging, 20W wireless charging, and 5W reverse wireless charging covers a wide range of power needs in a single device. The 120Hz OLED display with 1300 nits brightness, Gorilla Glass 5 protection, and IP54 water resistance make it a capable daily driver for those who use their phone heavily in varying environments. Users who value camera control and flexibility will also find the 108MP main sensor with OIS, extensive manual controls, slow-motion, timelapse, and 1440p video recording a practical fit for casual to enthusiast-level photography.

Who is this NOT for?

Users who require 5G connectivity will find this phone unsuitable, as cellular support is limited to LTE. Those looking for a device that integrates smoothly into a wired audio setup will be hampered by the absence of a 3.5mm headset jack, and without aptX or its variants, wireless audio options are limited to LDAC only. The lack of HDR10 or Dolby Vision display support makes it a weaker fit for users who prioritize HDR content consumption, and the absence of direct OS vendor updates may be a concern for anyone who places importance on timely long-term software security and feature updates.

The 12GB of RAM, broad sensor suite, and timelapse and slow-motion video support further strengthen its case as a capable daily device. Its gaps — namely the absence of 5G, HDR display support, a headset jack, and direct vendor OS updates — set some boundaries on who will get the most out of it. For users who prioritize charging versatility, display quality, and camera flexibility within an LTE-only ecosystem, the Note 40 Pro 4G delivers a coherent and feature-rich package that holds up well across a broad range of everyday use cases.
