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?
In: Technology
One of two things is happening:
1) The phone charger may have a capacitor inside it that’s storing a small amount of electrical charge, even after you’ve pulled it from the wall.
2) The motion of inserting the charger into your phone may be inducing a slight current, causing your phone to think it’s being charged. This is much more unlikely, since it requires there to be a magnet somewhere in the mix.
