OnePlus 13s review: specs, battery & used prices

Summary

The OnePlus 13s is OnePlus's 2025 compact flagship: a Snapdragon 8 Elite, a 6.32-inch 120 Hz OLED, and a 5,850 mAh battery in a 185 g body with an IP65 rating. The 12/256 GB tier lists at $650 new, and the 12/512 GB tier trades around $577 used across two sales — a meaningful early discount for a current-generation platform with three OS-update years declared.

Display and design

The 6.32-inch OLED refreshes at 120 Hz with 1,600 nits of peak brightness; screen quality is 72/100. Compactness is the defining axis at 89/100 — a true one-hand flagship in a market of 6.7-inch normals. IP65 covers dust and water jets, short of submersion.

Performance

The Snapdragon 8 Elite posts everyday responsiveness 89/100 and gaming 79/100 — a 2025 flagship platform one step below the newer Elite Gen 5, still without a practical ceiling for anything on the market.

Camera

The camera pairs a 50 MP main sensor with optical stabilization and a 50 MP ultrawide; there is no telephoto, and video tops out at 8K30. Camera score is 40/100 — the axis where the compact format costs: no zoom stage, and the processing is a tier below the full-size 13 series.

Battery and charging

Battery life scores 57/100 on the 5,850 mAh cell — silicon-carbon density lets a compact body carry flagship endurance — while 80 W charging scores 61/100. Compactness and battery are simultaneously above average, which is rare.

Verdict

At $650 new or around $577 used, the OnePlus 13s is the compact-flagship pick of its generation: one-hand size, flagship platform, large battery — paid for with the missing telephoto. The OnePlus 13 is the full-size sibling with the complete camera set, and the OnePlus 13R is the value rung below.
