I have a USB charger plugged directly to the wall outlet without my phone plugged in. I remove the charger from the outlet and then connect the charging end to my phone. My iPhone makes the charging sound and shows that it’s charging for a second, then stops charging. Why does this happen?
PS. I noticed this in Europe since I’m currently traveling. I don’t believe I’ve seen this happen back home (US). Does it have to do with the higher voltage in Europe?

There is a capacitor inside the charger. It holds electricity, and take a few seconds to bleed down to zero. The phone sees the residual power in the charger, then it’s gone.
