6,700mAh battery, 120Hz screen, NFC and 50MP camera but only using HD+ screen with Helio G81, will TECNO SPARK 50 be enough to put pressure on the popular smartphone group that is competing increasingly fiercely?
TECNO has included SPARK 50 in its official product list in Vietnam. According to the product page and specification sheet of TECNO Vietnam, the version for the Vietnamese market is equipped with a 6,700mAh battery, 18W fast charging, 6.78 inch screen with 120Hz refresh rate, 50MP main camera, NFC, infrared control and IP64 dust and water resistance standard.
A special point to note is that SPARK 50 parameters vary by market. The image being shared shows a 6,700mAh configuration and advertised memory of 128GB ROM and 12GB RAM, of which 8GB is expandable RAM. However, TECNO Vietnam confirmed that the Vietnamese version is 128GB and 8GB advertised, including 4GB of expandable RAM, and the battery is 6,700mAh. Meanwhile, the TECNO Nepal website now announces the SPARK 50 with a 7,000mAh battery and other memory configurations. Therefore, you should not take all the parameters on a market's advertisement to apply to machines sold in Vietnam.

The parameters in the table above are published directly by TECNO Vietnam on the SPARK 50 technical specifications page.
The 6,700mAh battery becomes the biggest highlight. TECNO said the device uses a 6,700mAh battery combined with 18W fast charging. This is a remarkable capacity for a popular smartphone, aimed at users who prioritize long usage time rather than extremely high charging speed. However, the 18W charging rate also means that buyers should not expect fast recharging capabilities commensurate with the large battery capacity.
120Hz screen but only HD+ resolution. SPARK 50 uses a 6.78-inch perforated screen with a maximum refresh rate of 120Hz, while the resolution announced by TECNO is 720 × 1600 pixels. This configuration prioritizes page scrolling smoothness and energy efficiency, but sharpness cannot be considered an advantage if placed next to smartphones in the same segment using Full HD+ screens.
50MP AI camera and FlashSnap are the points TECNO emphasizes. The rear camera has a resolution of 50MP. TECNO introduces FlashSnap using a high-speed shutter combined with the BestMoment AI algorithm to support recording moving subjects and selecting the appropriate frame. The 8MP front camera is also equipped with its own flash.
Helio G81 clearly identifies SPARK 50 as a popular 4G smartphone. MediaTek Helio G81 processor comes with Android 16 and connectivityMaximum 4G. This is also an important point to avoid confusing SPARK 50 with SPARK 50 5G. The 5G version is a different device, using Dimensity 6400 5G+, 6,500mAh battery and 45W charging according to TECNO's published specifications.
In addition to the basic configuration, SPARK 50 also has NFC, infrared device control, GPS, Wi-Fi, Bluetooth, FM, OTG, side fingerprint sensor, dual speakers and DTS. TECNO also promotes fall protection from a height of up to 1.8m with IP64 standard. IP64 is meant to protect the device against dust and water splashing from many directions, but does not mean the device can be submerged in water like devices reaching IP67 or IP68.
Another notable detail is that SPARK 50 in Nepal is not exactly the same as SPARK 50 in Vietnam. The TECNO Nepal page currently records a 7,000mAh battery, while TECNO Vietnam records 6,700mAh. A technology source in Nepal also noted that 6GB RAM and 128GB versions are sold in the country with a 7,000mAh battery. This difference shows that TECNO is implementing a regional configuration, so the exact parameters need to be reconciled according to the distribution market.
Overall, TECNO SPARK 50 Vietnam version focuses quite clearly on four factors including large capacity battery, 120Hz screen, 50MP camera and IP64 durability, while adding NFC and infrared which are useful in daily use. The trade-off is the HD+ screen, the Helio G81 platform only supports 4G and 18W charging capacity. These are the factors that will determine the actual competitiveness of SPARK 50 when the official selling price and distribution programs in Vietnam are placed next to smartphones of the same price.happy song.
