If you have a wireless charging case and are using a charger compatible with the Qi standard, place the side of the case with the status indicator facing up. The status indicator should light up for a few seconds, then turn off and continue charging. If the indicator light is not on, reinstall the charging case. If the charging case is still not charged, try charging it using the cable that came with the case.
