Why my Battery drains so Fast?!
I have an iPhone 5S which I traded a broken Galaxy S6E for.The phone looks good, problem is that the battery drains a bit quicker than expected. It gets a bit warm but very little. It continues to drain overnight or in my pocket, Wien 20/30/40% randomly shuts down and it doesen’t accept all the cables. He gave me the original cable which seems to work for now.I’ve read on the Internet that it may be iOS 11.2.1 that causes issues, but not sure.
Is dit een goede vraag?
