A
total battery drain is commonly overlooked, yet it could be the p
rimary cause of your phone's black screen. With that in mind, try
charging your iPhone for at least
30 minutes by plugging it into the charger. Use the charger that came with our smartphone or the original charger. Otherwise, charge your iPhone using an alternative charger that is compatible with it.
If the charging indicator does not appear after plugging your iPhone into the charger, force a restart while the phone is attached to the charger. To force a restart on your iPhone, simply follow the steps outlined above.
If the black screen problem was caused by an error, this should resolve it.
