[Problem] Slow charging & No charging indication
I am on a trip to Hong Kong and the Voltage here is different. As the iphone charger works on different voltage I connected it for charging. But it not showing the charging indication of the battery in the locked screen or the charging icon on the top. I left it on charger over night and after about 8 hours, it was charged by 70%. But there was no indication on phone that it was charging.
Any idea what could be wrong? Any way to fix the indicator or slow charging problem? Is there any chance of voltage difference damaging the iphone/battery or charger?
