NeoTeo's verdict

Which of the two is the better buy

The Tecno Spark 40 Pro is the stronger choice for display and battery priorities, with 4500-nit peak brightness and a 144 Hz refresh rate versus 1700 nits and 120 Hz on the Spark 30 Pro. Their overall scores are nearly even, while the 30 Pro has the clearer main-camera advantage.

The 40 Pro also raises resolution from 1080 × 2436 px to 1224 × 2720 px and pixel density from 393 to 440 ppi. Its 5200 mAh battery and 45 W charging beat the 30 Pro’s 5000 mAh and 33 W; it also supports reverse charging. The body is thinner and lighter at 6.7 mm and 170 g, versus 7.4 mm and 185 g.

For the main camera, the Spark 30 Pro pairs 108 MP with a larger 1/1.67″ sensor; the Spark 40 Pro has 50 MP and a 1/2.8″ sensor. In return, the 40 Pro runs Android 15 rather than Android 14 and is rated for drops up to 2 m. The choice comes down to camera priority versus the brighter display and larger battery.
