My phone will be plugged in all night and when I unplug it in the morning and start to use it it shuts off. I have to restart it and it shows the battery went from 100% to 0%. So I plug it back in and it boots up eventually and says 10% battery life how the !&&* can I go for 100% to 10% in seconds I don’t understand it something is not communicating I think it happened with my last iPhone update it’s just a way for these ##&&%#@ to make us buy a new phone be damned
