OnePlus has started rolling out a new OxygenOS update for the OnePlus 13, delivering two highly anticipated features—bypass charging support and native 50MP photo editing—alongside the January 2026 Android security patch. The update is currently rolling out in India in phases and is expected to reach more users in the coming days.
The firmware, labeled OxygenOS 16.0.3.501, brings meaningful improvements aimed at gamers, power users, and mobile photography enthusiasts, reinforcing OnePlus’ focus on performance and long-term battery health.
Bypass Charging Comes to OnePlus 13
One of the headline additions in this OnePlus 13 OxygenOS update is bypass charging, a feature previously introduced on the OnePlus 15. When enabled, bypass charging allows the phone to draw power directly from the charger instead of routing it through the battery during high-load activities.
This is especially useful for:
- Mobile gaming
- Live streaming
- Navigation
- Video playback
- Extended screen-on usage
By reducing battery stress and heat generation, OnePlus bypass charging helps preserve battery longevity while maintaining stable performance—something mobile gamers have been actively requesting.
Full-Resolution 50MP Photo Editing Without Quality Loss
The update also significantly upgrades the Photos app. Users can now edit images up to 50 megapixels directly on the device without compromising image quality. This enhancement makes the OnePlus camera update particularly appealing to creators who rely on detailed, high-resolution shots.
Whether cropping, adjusting exposure, or applying enhancements, edits now retain original clarity—bringing the OnePlus 13 closer to professional-grade mobile photography workflows.
Additional Improvements and Security Enhancements
Beyond battery and camera upgrades, OxygenOS 16.0.3.501 introduces several quality-of-life improvements:
- New app categories (“Office” and “Finance”) in the app drawer for better organization
- Enhanced Private Safe controls, including file search, sharing, and slider-based access
- January 2026 Android security patch for improved system protection
- A new “Reply with SMS” toggle to customize incoming call behavior
Rollout Details
- Device: OnePlus 13
- Firmware version: CPH2649_16.0.3.501 (EX01)
- Region: India (initial batch rollout)
As with most OxygenOS updates, this release is being pushed incrementally. OnePlus recommends users wait a few days if the update hasn’t appeared yet.
Why This Update Matters
This OnePlus 13 OxygenOS update stands out because it focuses on real-world usability rather than cosmetic changes. With bypass charging addressing long-standing battery concerns and 50MP photo editing enhancing creative freedom, OnePlus continues to deliver updates that resonate strongly with its loyal user base.
For gamers, photographers, and power users alike, this update makes the OnePlus 13 an even more compelling flagship in early 2026.
