## What reviewers say

**OnePlus 13** — Four whitelisted testers (Notebookcheck, GSMArena, Tom's Guide, Engadget) all lab-benchmarked the OnePlus 13 and rate it a top-value flagship: class-leading 6,000mAh battery life, fast Snapdragon 8 Elite performance, and quick charging. Shared knocks: real-world brightness falls short of the 4,500-nit claim, heavy GPU throttling, and merely good low-light cameras. (4 sourced reviews.)
