NeoTeo's verdict
Which of the two is the better buy
The Tecno Spark 40C is the better fit for buyers who want more battery and a smoother display; the Spark Go 1S stands out for its AnTuTu result and NFC. Their overall scores are close.
The Spark 40C pairs a 6,000 mAh battery with 18W charging, versus 5,000 mAh and 15W on the Go 1S. It also has a 120Hz display instead of 90Hz, 8GB of RAM instead of 3GB, and IP64 rather than IP54 resistance. The Go 1S, meanwhile, scores 375,000 in AnTuTu against 250,000 and adds NFC, which the 40C lacks.
Both have a 6.67-inch IPS LCD display with 720 × 1,600 px resolution and 263 ppi, plus expandable eMMC 5.1 storage. The 40C runs Android 15 and the Go 1S Android 14; both include a 3.5mm headphone jack and stereo speakers.
