Tecno Spark 50s Specifications, Features and Performance

The Tecno Spark 50s features a 6.78-inch display with a 120Hz refresh rate, a MediaTek Dimensity 6400 chipset and a 6,500mAh battery. The smartphone also supports 5G connectivity, 45W wired charging and runs on Android 16 with HiOS 16.

It comes with a 50MP rear camera, an 8MP front camera and 128GB of internal storage, with either 6GB or 8GB of RAM. Other features include expandable storage, dual-SIM support and an IP64 rating for dust and water splash resistance.

Design And Build

The Tecno Spark 50s measures 167.9 x 79.3 x 8.2mm and weighs 210g. Its dimensions accommodate the large display and battery, although the weight may be noticeable during extended use.

The phone supports two Nano-SIM cards, allowing users to operate two mobile numbers on the same device. It is available in Burgundy Red and Breeze Blue.

For protection, the Tecno Spark 50s has an IP64 rating, which provides dust protection and resistance to water splashes under specified test conditions. It is also listed as drop-resistant from heights of up to 1.5 metres and compliant with MIL-STD-810H.

However, MIL-STD-810H compliance does not automatically make the phone fully rugged or suitable for extreme conditions. Users should still take care to protect it from severe impacts and excessive exposure to water.

Display

The Tecno Spark 50s features a 6.78-inch IPS LCD with a 120Hz refresh rate and a listed brightness of 560 nits.

The 120Hz refresh rate allows the screen to refresh more frequently than a conventional 60Hz display. This can make supported animations, scrolling and navigation appear smoother.

The display has a resolution of 720 x 1576 pixels, a 19.5:9 aspect ratio and a pixel density of approximately 256 pixels per inch. Although the screen provides a large viewing area for videos, web pages and social media, its resolution is below Full HD.

The screen-to-body ratio is approximately 84.2 per cent, giving the display a substantial presence on the front of the device.

Performance

The Tecno Spark 50s is powered by the MediaTek Dimensity 6400 chipset, built using a 6nm process. Its octa-core CPU consists of two Cortex-A76 cores running at up to 2.5GHz and six Cortex-A55 cores running at up to 2.0GHz.

Graphics processing is handled by the Mali-G57 MC2 GPU. This hardware provides the foundation for everyday activities such as messaging, web browsing, video streaming and social media use.

The chipset also supports 5G connectivity, allowing users to access compatible fifth-generation mobile networks where available. Actual network speeds depend on coverage, the mobile operator and other network conditions.

The phone runs Android 16 with Tecno’s HiOS 16 interface. Actual performance will depend on the apps being used, software optimisation and the phone’s memory configuration.

Memory And Storage

The Tecno Spark 50s comes in two listed memory configurations:

• 128GB storage with 6GB RAM
• 128GB storage with 8GB RAM

Both configurations use UFS 2.2 storage. The 8GB RAM version provides more physical memory for managing multiple apps, although multitasking performance also depends on software optimisation and usage patterns.

The phone includes a dedicated microSDXC card slot for expandable storage. This allows users to add space for photos, videos, documents and other files without relying solely on the built-in 128GB.

The maximum supported microSD card capacity is not specified in the supplied details.

Camera

The Tecno Spark 50s has a single 50MP rear camera with an f/1.8 aperture and autofocus. It also includes an LED flash for situations where additional light is needed.

The supplied specifications confirm video recording support but do not state the maximum recording resolution or frame rate. These details should not be assumed without further confirmation.

For selfies and video calls, the phone features an 8MP front camera with an f/2.0 aperture. Video recording is also supported by the front camera.

Actual photo and video quality will depend on lighting conditions, subject movement, camera settings and software processing. The megapixel count alone does not determine the overall quality of images.

Battery And Charging

The Tecno Spark 50s packs a 6,500mAh battery, giving it a substantial battery capacity for smartphone use.

Battery life will vary according to screen brightness, network coverage, gaming, video playback and the apps running on the phone. The 120Hz display and 5G connectivity can also affect power consumption depending on how they are used.

The device supports 45W wired charging. Its charging time will depend on the starting battery level, temperature and charging conditions.

Another listed feature is bypass charging. This can direct power to the phone’s system during supported activities rather than routing all incoming power through the battery. When supported and enabled, it can help manage battery heat during certain demanding tasks.

Software And Features

The Tecno Spark 50s runs Android 16 with HiOS 16, Tecno’s customised Android interface.

The phone has a side-mounted fingerprint sensor for biometric unlocking. Other sensors are listed in the supplied specifications, but their individual types have not been specified.

For audio, the device includes a loudspeaker and a 3.5mm headphone jack. The headphone jack allows users to connect compatible wired earphones without needing a USB-C adapter.

Connectivity

The Tecno Spark 50s supports GSM, HSPA, LTE and 5G networks. Its listed 5G compatibility includes standalone (SA) and non-standalone (NSA) modes.

Its network specifications include the following bands:

• 2G: GSM 850, 900, 1800 and 1900
• 3G: HSDPA 850, 900 and 2100
• 4G: LTE
• 5G: SA and NSA

The phone supports dual-band Wi-Fi 802.11 a/b/g/n/ac and Bluetooth 5.3, including A2DP and Low Energy support.

For location services, it supports GPS, Galileo, GLONASS, BeiDou and QZSS. Charging and data connectivity are handled through a USB Type-C port.

NFC is not available according to the supplied specifications. The radio feature is listed as unspecified, so its availability has not been confirmed.
