OnePlus 15 and 13s Get March Security Patch with New Features

OnePlus has started rolling out the OxygenOS 16.0.5.700 update for the OnePlus 15 and OnePlus 13s in India. The update is delivered in phases via an incremental over-the-air rollout, with initial batches reaching a limited number of users before broader availability in the coming days.

For the OnePlus 15, the new firmware version is CPH2745_16.0.5.700(EX01), while the OnePlus 13s receives version CPH2723_16.0.5.700(EX01). This update includes the March 2026 security patch along with improvements and new tools designed to enhance device performance and user experience.

Users are advised to check for updates manually via the settings menu if the OTA notification has not yet appeared. The update ensures better security, bug fixes, and optimized system performance for both smartphones.

The incremental rollout approach helps OnePlus identify and resolve potential issues before wider deployment, minimizing risks for users. Early adopters report improved stability and smoother interactions following the update.
