There is no way to reset or recalibrate the power adapter.
Probably just a coincidence that the power adapter has failed after charging the android phone, or maybe that had something to do with it.
All package contents are included with the iPhone's warranty. If the iPhone remains under warranty, make an appointment at an Apple store if there's one nearby to have the power adapter checked and exchange under warranty if needed.
