NeoTeo's verdict
Which of the two is the better buy
The Tecno Spark 40C is the stronger all-round buy for anyone prioritizing battery, memory and storage: it offers 6,000 mAh, 8 GB of RAM and 256 GB. The Tecno Spark Go 3 suits anyone seeking higher measured performance, with 310,000 AnTuTu points versus 250,000. Their overall scores are close at 4.7 and 4.6.
The Spark 40C leads on battery with 6,000 mAh versus 5,000 mAh and charges at 18 W versus 15 W, although both charging figures are below typical market levels. It also adds reverse charging. Its 8 GB of RAM and 256 GB beat the Go 3’s 4 GB and 128 GB, but eMMC 5.1 storage is slower than the Go model’s UFS 2.2.
The Spark Go 3 answers with 310,000 AnTuTu points versus 250,000 and Bluetooth 5.4 versus Bluetooth 5.3. Its IP64, IP67 and MIL-STD-810H protection is more comprehensive than the Spark 40C’s IP64. Both share a 720 × 1,600 IPS LCD at 120 Hz, Android 15, expandable storage, stereo speakers and a 3.5 mm jack.
