OnePlus started rolling out OxygenOS 16.0.3.501 (CPH2649_16.0.3.501 EX01) for the OnePlus 13 in India. The update brings several useful features focused on photos, battery life, and security.

Photos and Battery
The Photos app can now edit images up to 50 million pixels without losing quality. The update adds bypass charging, which works during gaming, streaming, video watching, and navigation. When you plug in your charger during these activities, power goes directly to the phone instead of the battery. This protects battery health and reduces overheating while you use the device.
Organization and Security
Drawer mode now includes “Office” and “Finance” categories to help you find apps faster. The update also includes the January 2026 Android security patch.
Private Safe Updates
Private Safe got three new features. You can browse files using a side slider, search for files inside folders, and share files stored in Private Safe.
Calling Feature
A new “Reply with SMS” switch lets you hide the SMS reply option when calls come in. Find it in Contacts, then Settings, then Answer/End calls, then Reply with SMS.

The update rolls out in batches. A small group gets it first, then more users receive it over the next few days.
