Coolpad Cool 40i

The Coolpad Cool 40i has a non-folding, fixed-form design measuring 166.2 mm tall, 77 mm wide, and 8.3 mm thin, with a total volume of 106.22 cm³. It weighs 202 g, which sits on the heavier side for a device of its dimensions. The phone offers no water resistance of any kind and does not feature a rugged build, meaning it lacks protection against dust, moisture, or physical stress beyond standard handling.

The Coolpad Cool 40i features a 6.56″ IPS LCD touchscreen with a resolution of 720 x 1612 pixels and a pixel density of 269 ppi. It supports a 90Hz refresh rate, which allows for smoother on-screen motion during everyday use. The display does not include branded damage-resistant glass, and it lacks support for HDR10, HDR10+, Dolby Vision, and Always-On Display functionality. There is no secondary screen, keeping the device to a single-panel layout.

The Coolpad Cool 40i is powered by the MediaTek Helio G37 chipset, built on a 12 nm process and configured with an octa-core CPU running at 4 x 2.3 GHz and 4 x 1.8 GHz using big.LITTLE technology, alongside a PowerVR GE8320 GPU clocked at 650 MHz with a turbo ceiling of 680 MHz. The device comes with 6GB of DDR4 RAM running at 1600 MHz across two memory channels, offering a maximum memory bandwidth of 13.9 GB/s and a maximum supported memory amount of 8GB, while 256GB of eMMC 5.1 internal storage handles local data. The SoC supports 64-bit processing, multithreading, integrated LTE, integrated graphics, DirectX 12, OpenGL ES 3.2, and OpenCL 1.2, and includes hardware-level security features such as NX bit and TrustZone. In Geekbench 6 testing, the chipset scores 205 in single-core and 911 in multi-core workloads.

The Coolpad Cool 40i features a dual-lens rear camera system led by a 50 MP primary sensor paired with a 0.3 MP secondary lens, both using a CMOS sensor without back-side illumination. The main camera supports phase-detection autofocus for stills, continuous autofocus during video, touch autofocus, and manual controls for focus, exposure, ISO, and white balance, along with HDR mode, burst shooting, in-camera panoramas, and slow-motion video recording. Video capture tops out at 1080p at 30 fps, with no optical zoom, no optical image stabilization, and no support for HDR10 or Dolby Vision recording. A single LED flash is present on the rear, while a dual-tone or RGB flash is absent, and there is no front-facing flash. The 8 MP front camera has an aperture of f/2 and is a single-lens setup positioned conventionally — not under the display — and does not shoot in RAW format or capture 360-degree panoramas.

The Coolpad Cool 40i runs Android 14 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, camera and microphone access management, and the ability to block app tracking, though cross-site tracking blocking and Mail Privacy Protection are not present. On the usability side, the OS supports dark mode, dynamic and manual theme customization, customizable notifications, a media picker, notification permission controls, split-screen multitasking, Picture-in-Picture, full-page scrolling screenshots, widgets, sharing intents, a child lock, and an extra dim mode for the display. It also offers on-device machine learning, offline voice recognition, voice commands, phone tracking, multi-user support, a battery health check tool, and the ability to play games while they are still downloading. Features not included are focus modes, app offloading, Wi-Fi password sharing, Quick Start, and the ability to function as a PC. Direct OS updates from the vendor are not supported, and the platform is noted as free and open source.

The Coolpad Cool 40i is equipped with a 4500 mAh rechargeable, non-removable battery that supports fast charging at up to 10W via cable. A battery level indicator is present, giving users a clear read on remaining charge. Wireless charging is not supported, so the device relies entirely on wired connections for power replenishment.

The Coolpad Cool 40i has a notably limited audio profile. It does not feature stereo speakers, relying instead on a single-channel output. On the wireless audio side, none of the high-quality Bluetooth codec standards are supported, including aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC, which restricts the options for lossless or enhanced wireless audio playback. A built-in radio is also absent.

The Coolpad Cool 40i covers the core connectivity bases with Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), Bluetooth 5.0, NFC, and a USB Type-C port running on USB 2.0. It accepts a single SIM card and does not support 5G, keeping it to LTE cellular connectivity. For navigation, the device includes GPS with Galileo support, a compass, a gyroscope, and an accelerometer, while a barometer, infrared sensor, heart rate monitor, ANT+, motion tracking, and optical tracking are all absent. The fingerprint scanner provides biometric security, though 3D facial recognition and an iris scanner are not available. Storage can be expanded via an external memory slot. Features such as satellite emergency SOS, crash detection, DLNA certification, HDMI output, a built-in projector, and a stylus are not part of the package.

The Coolpad Cool 40i includes a video light, allowing it to illuminate scenes during video recording. The display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
