Can an iPhone charger kill a battery?
So I heard this story from a customer. He bought a charger for his iPhone 5s and plugged it in, first it charged, later it stopped and the phone wouldn't charge anymore. Later, the battery died and he bought another charger, but nothing happened when he plugged it in.
So I looked like a few days ago and the charging port works fine when I connect the old battery, but when I connect the new one, it doesn't charge and it doesn't turn on.
Now I don't want to be a jerk and say, it's your fault because it's probably a really bad charger.
So my question is, is it possible that the charger killed the entire battery.
By the way, the battery was new and fresh from iFixit.
Is this a good question?
