Design & Build

Tecno Spark 40 features a cutting-edge DECO design with a fashion-first approach. Its ultra-thin 7.67mm profile and 188g weight make it one of the slimmest devices in its segment. The color lineup—Ink Black, Titanium Grey, Veil White, Mirage Blue, and Sunlight Orange—caters to both minimalists and vibrant-style users.

Display

The Spark 40 includes a 6.67-inch 120Hz hole-punch display. Although it runs at a 720×1600 resolution, the high refresh rate improves fluidity for gaming, scrolling, and animations. Outdoor readability is boosted with Wet Touch support, allowing interaction even when the screen or fingers are slightly wet.

Performance

Powered by either the MediaTek Helio G81 or G91 (NFC version), the Spark 40 handles daily multitasking smoothly. With RAM options up to 16GB (including extended memory), the device benefits from TDV-certified 4-year fluency, ensuring long-term usability without noticeable slowdowns.

Camera System

A 50MP ultra-clear main camera captures detailed shots across lighting conditions. Tecno's FlashSnap algorithm enhances moving subject photography, preserving clarity even during motion. The 8MP front camera with dual flash supports well-lit selfies and AI-enhanced portrait processing.

Battery Life

The 5200mAh battery offers excellent endurance, supported by 45W Super Charging capable of reaching full charge in approximately 55 minutes. The battery is rated for over 2,000 charge cycles, retaining more than 80% capacity even after 5 years—unusual longevity in its class.

Durability

The Spark 40 offers IP64 dust and water resistance, making it safe in rain, splashes, or dusty environments. A reinforced chassis built with high-strength materials provides drop resistance up to 1.5 meters.

FreeLink enables two-way voice calls and message exchange in environments without cellular coverage using Bluetooth-based device-to-device connectivity. It supports a communication range of up to 500 meters in open environments, ideal for hiking, concerts, parking lots, or disaster scenarios.
