Motorola Moto G31 review: specs, battery & used prices

Summary

The Motorola Moto G31 is Motorola's 2021 budget-AMOLED model: a 6.4-inch OLED, a Helio G85, and a 50 MP main camera at a $200 launch price. Used 4/64 GB units sell for around $113 with a deep sixteen-sale sample — the cheapest OLED phone in this comparison and a long-standing entry-level favourite.

Display and design

The 6.4-inch OLED runs at 60 Hz with a 700-nit peak — screen quality 38/100 on our axis, with OLED contrast doing the heavy lifting — in a 181 g body with compactness at 91/100 and IP52 splash protection.

Performance

The Helio G85 is a modest platform: gaming 0/100 and everyday responsiveness 26/100 on our axes. Daily communication apps run at a patient, steady pace; gaming is outside the envelope entirely.

Camera

The camera pairs a 50 MP main sensor with an 8 MP ultrawide and a 2 MP close-up lens. Our camera score of 19/100 is budget-honest: main-sensor daylight shots are the entire case, and they are adequate.

Battery and charging

The 5,000 mAh battery scores 40/100 on battery life, a genuine multi-day cell at this workload, while 20 W charging scores 2/100 — overnight rhythm is the contract. OLED contrast at this price was the reason the G31 stood out in its launch class, and the slim 181 g body keeps the multi-day phone carryable.

Verdict

At around $113 used with sixteen sales of depth, the Moto G31 is the entry-level OLED pick: real contrast, multi-day battery, and near-invisible price, with resale confidence at 100/100 confirming constant demand. Slow charging and the entry platform are the open secrets. The Moto G22 is the LCD sibling; the Galaxy A12 is the same-tier brand alternative.
