Battery life
My battery just started this last night on my iPhone 7 Plus. It was reading 65% charged and I picked it up and took a picture and it suddenly powered off. I turned back on while plugged in and it came back on reading 65% and then suddenly dropped to 10%. This keeps happening over and over. When I plug it in it starts charging up pretty fast, faster than normal. 1st time having this issue. Is it time for an upgrade or is this fixable?
iPhone 7 Plus, iOS 14
