OnePlus India is rolling out OxygenOS 16.0.3.501 for the OnePlus 13s. The update introduces bypass charging, a feature designed for gaming or streaming that lets the phone draw power directly from the charger, bypassing the battery to reduce heat and wear. It also enables 50MP photo editing within the OnePlus Photos app.

Bypass charging is a practical addition for power users who frequently charge while using demanding apps. The high-resolution photo editor targets mobile photographers who want more control without sacrificing quality. These features align with OnePlus's focus on performance and imaging, a competitive edge in the crowded Indian smartphone market.

The update also includes the January 2026 Android security patch, improved app categorization, and new Private Safe file management options. Incremental rollouts are standard, so not all users will receive it immediately. This release keeps the 13s relevant as OnePlus prepares for its next flagship cycle.
