NeoTeo's verdict
Which of the two is the better buy
The Tecno Spark 50 4G is the more complete buy for battery, storage, and camera, while the Spark 40C suits buyers who value measured performance and a lighter body. The Spark 50 4G has 7,000 mAh versus 6,000 mAh, UFS 2.2 versus eMMC 5.1, and Android 16 versus Android 15. The Spark 40C keeps the AnTuTu lead at 250,000 versus 235,000 and weighs 196 g versus 210 g.
The main camera creates a clear split: the Spark 50 4G offers 50 MP versus 13 MP, while the Spark 40C counters with an f/1.8 aperture versus f/1.9 and Dual LED versus LED flash. Both use a 720 × 1600 px IPS LCD display at 120Hz. The Spark 40C adds reverse charging, and both support 18 W fast charging.
Connectivity is very similar, but the Spark 50 4G adds NFC; both retain a 3.5 mm audio jack, infrared, and FM radio. Their overall scores are 4.7 and 4.9: the Spark 50 4G earns the stronger recommendation through its battery, storage, software, and camera, while the Spark 40C remains the alternative when lower weight and AnTuTu matter more.
