NeoTeo's verdict
Which of the two is the better buy
Tecno Spark Slim is the pick for buyers who value a sharper display and a light body: AMOLED, 144Hz, and 440 ppi versus the Tecno Spark 50's IPS LCD, 120Hz, and 256 ppi. It also leads overall at 5.5 versus 5.1, while the Spark 50 answers with a larger battery and 5G.
The Slim is easier to carry, weighing 156 g and measuring 5.9 mm thick versus 210 g and 8.2 mm for the Spark 50. Its display also delivers 1,224 × 2,720 px versus 720 × 1,576 px, with 89.1% usable surface versus 84.2%. The Spark 50 counters with Android 16 instead of Android 15 and 5G, which the Slim lacks.
The Tecno Spark 50 is the alternative for buyers who prioritize capacity: 6,500 mAh versus 5,160 mAh, although both support 45 W charging. The Slim adds reverse and bypass charging, plus Bluetooth 5.4 versus Bluetooth 5.3 and NFC; the Spark 50 retains a 3.5 mm audio jack. Its trade-off is the lower resolution and a considerably heavier design.
Tecno Spark Slim
The Tecno Spark Slim is the better buy for buyers seeking a 144Hz AMOLED display and a 156g body.
Tecno Spark 50
The Tecno Spark 50 is the better buy only when its 6,500mAh battery and 5G matter more than a superior display.
