You can't. The maximum charging power the iPhone XR can support is 15W, and using a 65W fast-charge adapter can damage the device because the power the device can support is not enough to use the higher power charger to its maximum performance. Apple officially recommends using an Apple-branded charger with 12W or higher power (such as the Apple 18W USB-C power adapter) for faster charging speeds.
1. Do not use 65W fast charge. 2. Because the maximum charging power of Apple XR is 18W, and the 65W fast charge exceeds its maximum charging power, it cannot be used. 3. Using 65W fast charge may cause damage to the battery of the Apple XR, so it is recommended to use the maximum power range of the adapter to charge to ensure battery life and safety.
Cannot support up to 18w
