Google Pixel 4a review: specs, battery & used prices

Summary

The Google Pixel 4a is Google's 2020 compact mid-ranger: a Snapdragon 730G, a 5.81-inch OLED, and a 3,140 mAh battery in a 143 g body. At $350 new it was the affordable entry to Pixel cameras; used 6/128 GB units now sell around $88 across a twelve-sale sample. Software support length was not declared in our data — for a 2020 Pixel this is the central risk of buying one today.

Display and design

The 5.81-inch OLED runs at 60 Hz with 700 nits of peak brightness; screen quality is 38/100. The 143 g body is the most compact in this wave — compactness 100/100 — and remains the whole reason some buyers seek this model out. No formal IP rating.

Performance

The Snapdragon 730G posts everyday responsiveness 32/100 and gaming 5/100. The daily workload of 2026 still runs on it — messaging, browsing, streaming — though app launches and heavy web pages expose the age.

Camera

The camera is a single 12 MP main sensor with optical stabilization, recording 4K30; camera score 10/100 on raw hardware, which understates what Google's processing extracted from it — this was the budget camera phone of its year. There is no ultrawide on board.

Battery and charging

Battery life is the model's structural weakness at 3/100 — the 3,140 mAh cell was small in 2020 and is small now, meaning a day of light use at best. 18 W charging scores 0/100. Resale is 100/100, the strongest value-retention on our scale.

Verdict

Around $88 used, the Pixel 4a is a compact-and-camera play with a battery that demands realistic expectations; as a secondary device it still works. The Pixel 6a is the direct successor with a faster chip and bigger battery, and the Pixel 5 is the same-year flagship-adjacent option with water resistance.
