Tecno Spark Slim review: specs, battery & used prices

Summary

The Tecno Spark Slim lives up to its name at 156 g — among the lightest phones in the catalog — while carrying a 6.78-inch 144 Hz AMOLED and a 5,160 mAh battery for $190 new in the 8/256 configuration. The Helio G200 is budget silicon (6/100 gaming), but the combination of an OLED panel, high refresh, and flagship-class thinness at this price is genuinely uncommon. US availability is limited, and secondhand pricing is untracked.

Display and design

The 6.78-inch AMOLED at 144 Hz is the standout: our screen score of 100/100 for the tier-leading combination of OLED technology, high refresh, and the 4,500-nit-rated peak (a laboratory figure; everyday brightness is far lower, but outdoor legibility is strong). The 156 g chassis with IP64 sealing earns a matching 100/100 compactness — together the best display-and-handling pairing under $200 we track.

Performance

The Helio G200 scores 41/100 everyday — competent for the interface and media — and 6/100 gaming, in line with the segment. No OS-update commitment is published for this model; software longevity should be assumed brief, which the price already implies.

Camera

A 50 MP main sensor carries the imaging alone: no ultrawide, no telephoto, and no published video spec. The 10/100 score reflects the hardware reality — daylight snapshots are acceptable, and that is the entire brief.

Battery and charging

The 5,160 mAh battery scores 43/100 on endurance despite the thin chassis — a real engineering point in its favor — and 45 W charging (26/100) is generous for the class. The slim body does not tax the battery as much as the spec sheet suggests it might.

Verdict

The Spark Slim is the most coherent Tecno in the catalog: it spends its budget on exactly the things a $190 phone should — OLED, refresh rate, weight, battery — and concedes the rest without apology. Buyers wanting more capability should look at the Nothing Phone (3a) Lite tier; buyers wanting a light, pleasant screen on a budget can stop here.
