NeoTeo's verdict
Which of the two is the better buy
The Tecno Spark Slim is the choice for higher performance, a lighter body, and newer connectivity. The Spark 40 Pro is only the better buy if it costs less: it offers no decisive advantage over its rival.
The Spark Slim uses the MediaTek Helio G200 and reaches 445,000 AnTuTu points, versus 410,000 for the Spark 40 Pro. It is also thinner at 5.9 mm versus 6.7 mm and lighter at 156 g versus 170 g; both sit below the usual level for these measurements. Both share a 6.78-inch AMOLED display, 144 Hz refresh rate, 4,500 nits, and 440 ppi, so the screen format does not decide the choice.
For connectivity, the Spark Slim has Bluetooth 5.4 versus Bluetooth 5.3; both include NFC, infrared, and a 3.5 mm audio jack. Both use Li-Polymer batteries and offer 45 W fast charging plus reverse charging. The Spark 40 Pro retains an f/2.2 front camera versus f/2 and IP64 with drop resistance up to 2 m, while the Slim combines IP64 with MIL-STD-810H, but neither difference changes the main recommendation.
