OnePlus 13R Battery Replacement
Compatible model: OnePlus 13R.
The OnePlus 13R houses a large 6000mAh battery, giving it strong daily range when healthy. The combination of a high-refresh-rate AMOLED display, 5G connectivity and an active camera system means the battery works continuously under normal use. As the cell ages, range reduces and the phone may struggle to reach the end of a typical day. Replacing the battery restores the full daily range the 13R was designed to deliver.
- Turnaround: Book ahead, parts sourced to order, typically 1 working day
- 6-month warranty on the replacement battery
- Walk-in near Liverpool Street Station or use our UK mail-in service
Signs your OnePlus 13R battery may need replacing
The 120Hz display and 5G radio are the two biggest continuous draws on the 13R battery. Heavy camera use and frequent fast charging also contribute to capacity fade over time.

- Device shutting down unexpectedly, particularly below 20 to 30 per cent charge
- Only reliable when plugged in for significant parts of the day
- Battery percentage dropping suddenly or behaving inconsistently
- Phone getting warm during normal use rather than only under load
- Screen lifting at the edges, this may indicate a swollen battery requiring urgent attention
- Check battery health by going to Settings, then Battery, then Battery Health on the OnePlus 13R
