Tecno Spark 40C vs Tecno Spark Go
Comparison between Tecno Spark 40C and Tecno Spark Go: camera, battery, fast charging, display, performance and colors, side by side. More phones from Tecno.
NeoTeo's verdict
Which of the two is the better buy
Tecno Spark Go is the pick for anyone seeking more performance and mobile connectivity: its MediaTek Dimensity 6400, UFS 2.2 storage and 5G separate it from the Spark 40C’s Helio G81, eMMC 5.1 and LTE. The Spark 40C stays close overall, but its strengths serve different priorities.
The Spark 40C suits buyers who value battery features, audio and selfies. Both phones have 6,000 mAh batteries and 18 W charging, but the 40C adds reverse charging and stereo speakers with DTS and DTS:X; the Go includes a charger and has a single loudspeaker. The Go brings a 50 MP rear camera and 1440p video, while the 40C pairs a 13 MP rear camera with an 8 MP front camera versus 5 MP on the Go.
Their displays are almost equivalent: both use IPS LCD panels with 720 × 1,600 px resolution, 120 Hz and Android 15. The Spark Go adds 5G and Bluetooth 5.4, against LTE and Bluetooth 5.3 on the 40C, while the 40C keeps its edge in reverse charging, stereo sound and slightly broader navigation support. Spark Go is the better fit for performance and mobile networks; Spark 40C for multimedia and battery features.
